Intelligent equipment for aging tests of energy storage power supplies

On the track where household energy storage power supplies, industrial and commercial energy storage power supplies, portable energy storage power supplies, as well as UPS and EPS products are steadily moving towards "ten-year reliable operation", accelerated aging tests are the core for verifying product lifespan, intercepting early failures, and fulfilling quality commitments.

I.Why does the "ten-year agreement" for energy storage power sources necessarily involve accelerated aging tests?

Energy storage power supplies are constantly exposed to harsh conditions such as high temperatures, heavy industrial loads, and frequent charging and discharging. There are potential risks such as cell degradation, component aging, and system stability decline, which tend to emerge gradually over time during long-term use. Traditional short-term functional tests can only verify the basic operational capabilities of the product and cannot predict its long-term reliability; while accelerated aging tests precisely simulate extreme environments and extreme working conditions, compressing the natural usage wear and tear over several years or even decades into a few weeks or months, enabling efficient and precise exposure of potential defects in the product and laying a pre-emptive defense line for the long-term stable operation of the product.

II. CPET: Three Core Technologies, Establishing an Efficient and Accurate Acceleration Testing System

CPET focuses on the testing requirements for energy storage power supplies in all scenarios. It is supported by three core technologies: high-temperature environment simulation, extreme power load, and efficient power feedback. Based on these technologies, it has established an intelligent aging test scheme covering all types of energy storage power supplies, achieving breakthroughs in test accuracy, efficiency, and economy, and perfectly meeting the needs of all stages of research and production.

Wide temperature range high-temperature test, precisely replicating extreme application scenarios

The equipment supports precise temperature control within the range of 65℃ ± 3℃, and can perfectly replicate various harsh working conditions such as outdoor exposure of energy storage power supplies, high temperatures in industrial and commercial energy storage rooms, and extreme environments of portable energy storage devices. Through high-temperature steady-state and cycling tests, it accelerates the assessment of the thermal stability and aging rate of battery cells, PCB boards, and power devices, effectively preventing performance drift and protection mis-triggering in high-temperature environments, ensuring stable operation of the product within the full temperature range and adapting to diverse application scenarios.

2. Maximum power load test, to comprehensively verify the reliability under all operating conditions

To address the core performance issues of energy storage power supplies, comprehensive tests including voltage, current, power limit pressure tests and multi-mode charging and discharging cycle tests are carried out, covering all operational scenarios throughout the product's entire life cycle:

● It can simulate extreme working conditions such as full load, overload, and transient sudden changes, accurately verifying the load-carrying capacity and protection mechanism of the energy storage power supply under peak power, and eliminating the failure risks in extreme conditions.

● Supports custom test programs such as constant current/constant voltage charging and discharging, and pulse charging and discharging. It comprehensively covers all scenarios including daily cycle of household energy storage, heavy-load discharging of industrial and commercial energy storage, and emergency switching of UPS/EPS. It is compatible with different product testing standards.

● The testing accuracy has reached the industry-leading level. The voltage/current measurement error is ≤ ±0.1%, ensuring the accuracy and reliability of the data used for product lifespan prediction and performance assessment, and providing a solid scientific basis for research and development optimization as well as quality control.

3. Efficient power feedback, achieving green testing, cost reduction and efficiency improvement

Unlike the severe energy waste in traditional resistance-based load testing, the intelligent equipment for CPET energy storage power supply aging test adopts advanced power energy feedback technology, efficiently recovering the electricity generated during discharge back to the power grid. Compared with traditional testing methods, the comprehensive energy consumption is reduced by more than 80%, significantly reducing the long-term testing costs of enterprises; at the same time, the equipment supports continuous and stable operation 24/7, meeting the large-scale aging testing requirements of production lines, and balancing green environmental protection and production efficiency, deeply aligning with the green development concept of the energy storage industry.

III. Comprehensive category coverage + intelligent control, suitable for diverse testing requirements

The intelligent equipment for aging tests of CPET energy storage power supplies comprehensively covers all types of products such as household energy storage power supplies, portable energy storage power supplies, industrial and commercial energy storage power supplies, UPS, EPS, etc. It adopts a multi-channel and modular design, and can flexibly customize the number of workstations and test schemes according to the production line scale and testing requirements of customers, suitable for different scenarios such as R&D samples, small batch verification, and large-scale production.

The system is equipped with an intelligent control system, enabling the entire testing process to be automated, significantly reducing the cost of manual intervention.

● One-click setting of test parameters, automatic execution of charge-discharge cycles, real-time monitoring of core data such as temperature, input and output voltage/current, and achieving full-process visual control.

● It has the functions of abnormal automatic warning and precise fault location. It can quickly identify potential problems such as internal resistance abnormalities and pre-warning signs of thermal runaway, and intercept non-compliant products in advance.

● Automatically generate standardized test reports, fully presenting core indicators such as cycle life, thermal stability, and load capacity. It can directly connect with the R&D optimization and quality certification processes, significantly improving work efficiency.
