30V 10A Charge 10A Discharge 40 Channel Battery Pack Testing Equipment&Aging Cabinet with Energy-Saving Function

1.1 Host Computer: The host computer software serves as the primary human-machine interaction tool, enabling functions such as device startup, shutdown, pause, and resumption. The host computer is responsible for collecting and processing battery aging data, and outputs the test results required by the client.

1.2 Central Control Unit (CCU): The CCU serves as the central control management software for the device, performing calculations on battery parameters such as capacity and charge level.

1.3 Bidirectional ACDC+LLC Isolated DCDC: During charging, this module draws power from the grid, which is then regulated by the bidirectional DCDC to charge the battery. During discharging, it feeds back the energy transmitted by the bidirectional DCDC to the grid.

1.4 Bidirectional DCDC (Buck/Boost): This non-isolated DCDC module provides all required current and voltage outputs for battery charging and discharging, including constant current charging, constant voltage charging, and constant current discharging.

II. Scope of Application

The system is designed for integrated cycle testing of lithium battery packs, including charging, discharging, functional testing, and data monitoring, and is applied to electric tools, solar energy storage, toy cars, scooters, electric bicycles, electric motorcycles, and home energy storage systems.
