The key role of lithium battery aging cabinets in the field of power batteries

As the new energy vehicle industry booms, power batteries, as the core power source, have a significant impact on the market competitiveness and user experience of electric vehicles due to their performance and safety. As a key testing device, lithium battery aging cabinets provide a full-lifecycle performance evaluation solution for power battery R&D, production, and maintenance by simulating actual charge and discharge cycles. These cabinets play an indispensable role in the industry.

The core value of a lithium battery aging cabinet lies in its high-precision environmental control capabilities and multi-parameter real-time monitoring system. The equipment can be set to operate within a temperature range of -40°C to 80°C and a humidity range of 10%-95% RH. It supports various charging and discharging modes, including constant current and constant voltage charging and constant current and discharge. For example, to simulate the operation of new energy vehicle batteries in low-temperature environments, the equipment can precisely control the temperature to -20°C and simulate rapid charging scenarios under these conditions, thereby verifying the battery's capacity retention and thermal runaway risk under extreme conditions.

During testing, the equipment continuously collects key parameters such as voltage, current, and temperature using built-in high-precision sensors. This data is integrated and analyzed to generate a detailed battery aging curve. For example, during testing at a leading power battery company, after 1,000 consecutive charge and discharge cycles, the aging cabinet accurately captured the point at which battery capacity decayed to 80% of its initial value, providing crucial data support for battery life prediction. This precise analysis, based on real-world data, helps companies gain a deeper understanding of battery performance variations under different operating conditions, thereby providing guidance for optimized battery design.
