Why do major companies all use aging testing equipment?

In the fields of power supply manufacturing, electronic equipment production and quality control, aging test equipment is the core equipment that ensures product reliability, eliminates early failures, and realizes the closed-loop of factory quality. Taking the CPET series of computer monitoring type electronic load temperature-controlled aging test equipment as an example, these devices simulate harsh conditions such as high temperature, high load and long-term operation to allow products to complete "extreme trials" before leaving the factory. This reduces the failure rate during after-sales service and improves the stability of the product throughout its entire life cycle. This is the core logic why major manufacturers are increasingly introducing aging test equipment. As a national-level specialized, innovative "little giant" enterprise, a national-level high-tech enterprise, a Guangdong Province Engineering Technology Research Center for New Energy Power Electronic Intelligent Testing Technology and Complete Equipment, a Shenzhen High-tech Enterprise, and a Shenzhen Double-Soft Enterprise, CPET Kexing Yuan has been deeply engaged in the field of power electronic testing for over a decade. With its fully independent core technologies and mature solutions, it has become a long-term testing partner for over 4000 industry leaders worldwide, including Huawei, BYD, Philips, Optibar, Samsung, and Luxeon Lighting. The stability and professionalism of its equipment have been fully verified in the aging verification of products with billions of units. I. The core value of aging testing equipment: Why is aging testing necessary? Taking power supply products as an example (server power supplies, PC power supplies, industrial power supplies, consumer electronic power supplies, special and military power supplies, adapters, chargers, LED driving power supplies, etc.), during the early usage stage of these products, hidden faults such as poor soldering, component deterioration, and parameter drift are prone to occur - these faults are difficult to detect through conventional testing, but will gradually manifest in the later daily use, directly affecting the product reputation and enterprise credibility. The aging test equipment uses accelerated stress testing to concentrate the problems that may be exposed during long-term use of the products within a short period of time for inspection. Its core value mainly lies in the following three points:●  Eliminate early failure products: Through continuous operation under extreme pressure loads, quickly eliminate products with process defects and poor components, avoiding substandard products from entering the market, significantly reducing after-sales maintenance costs and brand damage.●  Stabilize product performance: Let the power supply complete "acclimatization" under high-temperature and full-load conditions, optimize the stability of output parameters, ensure that the product meets performance standards and operates stably for a long time, and reduce the probability of faults during use.●  Data-based quality traceability: Accurately record core test data such as voltage, current, power, and efficiency throughout the process, automatically generate traceable reports, perfectly adapting to various quality management system requirements, and achieving traceability, traceability, and controllability of quality. II.

It strikes a balance between versatility and professionalism, and can flexibly adapt to the testing requirements of different types and specifications of power supplies, precisely matching the large-scale production and refined testing needs of major manufacturers. 1. Power Supply, Wiring and Precautionary Measures (Safety Foundation)●  Equipment Power Supply: Utilize three-phase AC380V/50Hz or single-phase AC220V/50Hz power supply, with mandatory grounding (equipped with 6mm² dedicated ground wire), and an additional leakage switch is installed at the front end. This approach aims to prevent electrical shock and equipment damage from the source, thereby eliminating safety risks such as electric shock and equipment failure.●  Wire Selection Standards: Strictly require the use of national standard multi-core copper wires, and prohibit the use of non-standard or damaged wires. This fundamentally eliminates potential safety hazards such as electric shock, short circuits, and fires, ensuring the safety of testing.●  Smoke Detection Protection: Both the product area and the load area are equipped with smoke sensors. Once abnormal situations such as smoke or fire are detected, the equipment will automatically cut off the main power supply, preventing the occurrence of fire accidents at the front end and safeguarding the safety of equipment, products, and personnel. 2. Electronic Load Module (Test Core)The equipment can select dozens of load modules such as CP8102, CP8104, and CP8108, which are fully self-owned intellectual property and independently developed and produced, based on the voltage, current and power requirements of the tested power supply. This enables it to fully meet the diverse testing needs of its partners. The load modules support 5 load modes, covering the vast majority of power supply testing scenarios and enabling precise testing of different types of power supplies.●  CC (Constant Current) mode: Compatible with constant voltage power supplies, it can maintain a constant pulling current, accurately testing the load capacity and stability of the constant voltage power supply.●  CV (Constant Voltage) mode: Compatible with constant current power supplies, it can stably output the test voltage, ensuring the accuracy and reliability of the constant current power supply testing.●  CR (Constant Resistance) / CP (Constant Power) mode: Simulates the impedance and power consumption of real electrical devices, reproducing the actual usage conditions of the product, making the test results more valuable for reference. ●  LED Load Mode: Specifically designed for the LED lighting industry, it can precisely simulate the Volt-Ampere characteristics of LED bulbs, matching the actual working scenarios of LED driver power supplies. The test is more targeted and professional.In addition, the load module supports multi-channel parallel connection, allowing for flexible expansion of high-power testing scenarios； at the same time, it comes with three protection mechanisms for over-temperature, over-current, and over-power, providing comprehensive safety protection during the testing process, avoiding damage to the equipment and the tested products, and meeting the testing requirements of large-scale and high-load production. 3.

It is user-friendly, comprehensive in function, and meets the requirements for efficient production line operation and refined management. It can significantly reduce labor costs:●  Simple operation process: Login → Parameter editing → Parameter import → Start aging. The steps are clear and easy to understand, and one can get started without professional training; each model only needs to be learned once, and later one can directly import aging parameters with a single click to improve the testing efficiency of the production line.●  Full coverage of core functions: Supports custom aging duration, time sequence switching, and can flexibly set voltage/current upper and lower limit judgment standards; real-time curve monitoring of the testing status, abnormal situations trigger automatic alarms, and at the same time, generate Excel reports and conduct SPC process capability analysis to achieve visualized, traceable, and analyzable testing data.●  Hierarchical permission management: Sets up administrator, engineer, and technician three-level user permissions, precisely adapting to the operation needs of different positions in the production line. It not only ensures operational safety but also prevents test parameter leakage or accidental operation, and is suitable for the requirements of large-scale factory standardized management. III. Standard Aging Process: Comprehensive Guide from Installation to OperationTaking the aging test of a 12V/1A adapter as an example, the complete operation process of the CPET Kexing Computer Monitoring Type Electronic Load Aging Test Equipment is clear and efficient, with standardized steps. It meets the batch testing requirements of the production line. The details are as follows:●  Equipment placement: Place it in an indoor area with dry and ventilated conditions, with the environmental temperature not exceeding 35℃. Leave at least 0.5m of space around the equipment for heat dissipation to avoid affecting the test accuracy and the service life of the equipment.●  Wiring connection: Complete the power-on of the equipment → Insert the product into the aging cabinet (using various methods such as plugs, sockets, terminals, or wire bundles) → Confirm the grounding situation. Ensure that the wiring is secure and the grounding is good throughout the process, and eliminate potential hazards such as poor contact and electric shock.●  Software settings: Log in to the system → Edit test parameters (select CC mode, set current 1A, voltage range 11.4–12.6V) → Set the aging time → Import parameters → Start the aging program. The entire process can be operated with one click, without the need for manual intervention.●  Operation monitoring: Real-time determine the test status through the channel indicator lights - green = normal operation, red = product failure, black = empty position; When the equipment detects an abnormality, it will automatically alarm and simultaneously record the abnormal data, facilitating later traceability analysis and process optimization. IV. Safety Operating Procedures: The "Red Line" for the Aging Test Equipment The aging test equipment involves dangerous factors such as high temperature, high pressure, and high current. During the operation, the following safety guidelines must be strictly followed to prevent any safety incidents and ensure the safety of personnel, equipment, and products:● Non-professionals are strictly prohibited from disassembling or repairing the equipment. There are risks of high-voltage electric shock and high-temperature burns inside the machine.

The working principle of the intelligent equipment for aging test of the CPET vehicle power supply assembly

The on-board power assembly is the core "energy hub" of an electric vehicle, integrating three key components: the on-board charger (OBC), the DC/DC converter, and the high-voltage distribution box (PDU). It can be designed as an independent unit or a two-in-one/three-in-one/multi-in-one integrated unit according to application requirements. As the core module of the vehicle's "electronic control assembly", it undertakes the core functions of electric energy conversion, transmission, and management between the external power grid and the battery power supply, the high-voltage system and the low-voltage system. It directly determines the charging speed, power efficiency, and operational stability of the electric vehicle. Product reliability is also an important guarantee for the safety and core performance of the entire vehicle. Therefore, conducting accelerated durability and lifespan tests on the on-board power assembly during the finished product stage is a key section for product quality verification, and professional aging testing equipment is the core technical support for this process.   The CPET new energy vehicle power supply assembly temperature control liquid cooling integrated aging test intelligent equipment is specially developed and designed for vehicle power supply assemblies (three-in-one/multi-in-one). It can conduct long-term aging, reliability verification, thermal management matching, and extreme condition simulation tests. It precisely resolves the industry pain points of traditional air-cooling aging equipment, such as uneven temperature distribution, low temperature control accuracy, insufficient heat dissipation capacity, and inability to replicate the actual vehicle liquid cooling conditions. It provides professional and efficient testing solutions for improving the reliability of vehicle power supply assembly products.   This equipment simulates, accelerates and strengthens the electrical, thermal, mechanical and environmental combined stresses that the on-board power assembly may encounter during actual use. It can expose the potential design flaws, performance degradation patterns and failure modes of the product in a much shorter period of time than the actual product lifespan. This provides scientific and precise experimental data basis for product design optimization, process improvement and reliability enhancement. The equipment adopts the core working logic of "maximum power pressure loading + liquid cooling temperature control cycle + ultra-high temperature ambient temperature control + multi-parameter full-dimensional monitoring + intelligent closed-loop collaborative control" to accurately replicate the real working scenarios of the on-board power assembly. The core working principle is as follows: When the tested on-board power assembly operates continuously under full power or variable power conditions, the internal OBC, DC/DC power components, inductors, capacitors and other core components will generate a large amount of heat loss. The equipment uses a dedicated liquid cooling circuit to precisely deliver the coolant to the internal flow channels of the power assembly, forcing the heat generated to be discharged, and through precise temperature control technology, stabilizes the temperature of the core components at the set range of 85℃ to 125℃.   At the same time, the system simultaneously collects key parameters such as temperature, flow rate, pressure, voltage, current, efficiency, insulation, etc. from all dimensions, and feeds them back to the central control unit in real time. It dynamically adjusts the cooling efficiency of the liquid cooling system and the intensity of power loading, establishing a "thermal-electric-fluid" multi-closed-loop collaborative control system. It precisely simulates extreme working conditions such as high and low temperature cycles, thermal shock, continuous full load, and start-stop shock of the entire vehicle, achieving efficient acceleration of the product aging process and precise exposure of early failure issues.   To achieve high-precision replication of the actual temperature conditions of the entire vehicle, the equipment is equipped with two core temperature control units: the liquid cooling temperature control circulation system and the ambient temperature control circulation system. It integrates the classic PID control algorithm and the AI intelligent algorithm to construct the temperature control logic. It can flexibly adjust according to the testing requirements and efficiently reproduce the temperature environment of the vehicle power supply assembly in the actual operation of the entire vehicle, ensuring the authenticity and accuracy of the testing scenario.   The equipment is equipped with a complete extreme power pressure loading system, which can fully replicate the actual power environment of the product's operation: The AC input end can provide 220V/380V three-phase/single-phase AC power supply, accurately simulating the actual input scenarios of household sockets and public AC charging piles, supporting ±20% voltage fluctuation, frequency fluctuation and harmonic injection, and capable of reproducing abnormal working conditions such as unstable grid voltage and harmonic interference; The DC high-voltage end can output a 300V~1200V high-voltage DC source, accurately simulating different working states of power batteries such as full charge, depleted charge, and dynamic voltage, supporting voltage step changes and ripple superimposition, and covering all kinds of power working scenarios of the vehicle power system during vehicle operation.   At the same time, the equipment is equipped with a high-performance multi-parameter monitoring and data acquisition system, which enables precise capture, efficient storage and intelligent management of all-dimensional data during the testing process. It can complete the detection and precise control of ambient temperature, as well as the detection of flow, pressure, liquid level, medium temperature and leakage status of the liquid path system, high-precision detection of electrical parameters such as voltage, current, power, insulation resistance, leakage current, etc., and full-dimensional detection of product functions including OBC charging status, DC/DC output voltage stabilization performance, PDU on-off and protection functions, CAN/LIN communication status, and fault code reading. The system supports high-speed data acquisition with customizable sampling frequency, enabling local secure storage of aging test data, and also supports seamless connection with the enterprise MES system for data cloud upload. It has functions such as viewing of test history curves, automatic generation of aging test reports, and intelligent analysis of product failure modes, providing comprehensive and precise data support for product design optimization and process improvement.   Intelligent control and all-scenario security protection are the core competitive advantages of this device: The system adopts a highly stable architecture of industrial PLC + upper computer software, is equipped with professional aging test software for computer monitoring, supports users to customize the aging test process, can flexibly set key parameters such as aging duration, power curve, temperature curve, and cycle times, and realizes the automatic and intelligent multi-closed-loop collaborative control of the "power loading → heat generation → liquid cooling cooling → temperature feedback → dynamic adjustment of loading/cooling" test process flow.   In terms of safety protection, the system adopts a comprehensive scenario-enhanced design. It can respond quickly within milliseconds and trigger emergency shutdown protection for various abnormal situations that may occur during the equipment operation, such as overheating, overvoltage, overcurrent, undervoltage, leakage in the liquid path, insulation failure, etc., ensuring the safety of the testing equipment and the tested products. At the same time, the equipment supports multiple industrial communication methods such as CAN3.0, CANFD, RS485, and TCP/IP, enabling remote real-time monitoring of the testing process and full-process traceability of the test data, significantly improving the efficiency and operational convenience of aging tests. In summary, the CPET Zhongyuan New Energy Vehicle Power Supply Assembly Temperature Control Liquid Cooling Integrated Aging Test Intelligent Equipment is essentially a professional reliability verification platform for vehicle power supply assemblies, integrating time acceleration and pressure simulation. It achieves "short-term advance" of product service life in the laboratory environment through precise multi-physical field coupling control and accelerated stress technology. It compresses the risks of vehicle power supply assembly usage on the road for months or even years into a few days, enabling early detection and resolution, providing crucial engineering technical support for enhancing the reliability and safety of new energy electric vehicles. At the same time, it also provides core technical support for the rapid iterative upgrade and continuous quality improvement of vehicle power supply assembly products.

Mobile power supply aging test process

Aging tests are a crucial quality inspection step in the production process of mobile power supplies. The core purpose is to verify the stability, safety and performance reliability of the products during long-term use, to identify potential faulty products, and to strengthen the quality defense line before leaving the factory.To ensure the accuracy of the test results and the standardization of the process, the specific test procedures are as follows: 1. Initial state check Place the mobile power bank to be tested (in its bare or semi-finished state) at the designated testing workstation. Complete the following comprehensive checks one by one to ensure that the initial state of the product complies with the testing standards: The appearance should be free of damage, scratches, deformation and obvious color differences; The buttons should press smoothly, have sensitive rebound, and there should be no sticking, malfunction or abnormal pressing feedback.The TYPE-C input/output interface is free from looseness, oxidation, or damage. The insertion and removal feel smooth. The pins of the interface show no bending, deformation, or damage. Only when all the initial conditions are met can the subsequent automatic aging test be carried out, to prevent the test results from being affected by initial defects. 2. Discharge test First, fully charge the mobile power bank to be tested. Then connect it to the Zhongyu Aging Test System. The system will discharge the battery at a constant current according to the preset standards until the cell triggers the protection voltage (the conventional standard is 3.0V per cell). The test system will automatically stop the discharge. The entire testing process is precisely recorded by the system for the discharge duration, and the actual output energy of the mobile power bank is calculated. This data directly determines the number of times it can charge devices such as mobile phones and tablets, and is one of the core indicators for evaluating the product performance. 3. Charging test After the discharge test was completed, the aging test system of Zhongkongyuan automatically connected the mobile power supply to the charging module. It was compatible with mainstream fast charging protocols such as UFCS integrated fast charging, USB-PD, FCP, SCP, Super VOOC, Mi Turbo Charge, Flash Charge, QC5, etc., precisely simulating the daily charging scenarios. During the test, the system monitored the entire charging process in real time, focusing on recording the curves of voltage and current changes, to verify whether the product could switch to constant current charging (during the fast charging stage) or constant voltage charging (during the trickle charging stage) modes, ensuring a stable charging process without abnormal fluctuations in voltage or current, or situations such as premature stopping of charging, overcharging, or insufficient charging. Ultimately, it could fully charge the battery without any abnormal issues such as premature stopping of charging, overcharging, or insufficient charging. 4. Cyclic charging and discharging test For mobile power supplies with high-quality standards, the "charging-discharging" complete process needs to be repeated for 3 to 5 cycles for testing. Through multiple cycle tests, the cycle life and capacity degradation rate of the battery cells, as well as the long-term thermal stability of the circuit board and the reliability of the charge-discharge protection mechanism are further verified. Precisely identify potential faults that may occur in the product during long-term repeated use, and ensure that the product meets the requirements for long-term use. 5. Data recording and exception handling The computer-monitored aging equipment provided by Zhongke Yuan's aging testing system can collect and automatically record the key parameters of each mobile power supply during the entire testing process in real time, including charging/discharging voltage, current, cell temperature, test duration, etc. This ensures that the data is traceable and verifiable. Before the test, the staff preset the safety thresholds for each parameter. Once the system detects that a certain parameter exceeds the threshold (such as excessively high cell temperature, abnormal voltage fluctuations, sudden increase or decrease in current, etc.), it will immediately send an alarm signal and automatically cut off the testing channel to prevent the expansion of the fault. At the same time, it marks the abnormal products to facilitate the subsequent technicians in identifying the cause of the fault and implementing corrective measures. Summary The Zhongyuanyuan aging test system is the core support for quality control of mobile power supplies - for manufacturers, it can effectively screen out faulty products, strengthen brand reputation, and reduce the rate of after-sales faults; for consumers, it is the last important line of defense to ensure daily usage safety, guarantee product performance compliance, and enhance the usage experience. It is both the "passport" for product manufacturing and the "pillar of confidence" for consumers to use the product with peace of mind.
