The tester features an energy return type design. The discharge energy from one channel can supply other charging channels or feed back into the power grid, yielding a charging energy-saving efficiency of up to 92% and discharge feedback efficiency up to 95%.
The equipment comes as a single unit with 4 channels. It supports parallel connection of up to 4 channels to accommodate different capacity expansion and testing requirements.
The voltage and current control/measurement accuracy is better than 0.1% (±0.1%RD + 0.1%FS), and data recording frequency goes down to 1 second per record.
The tester features industry-standard RJ45 and RS485 communication interfaces, making it convenient for integration with external factory network environments and systems.
It features data storage recovery for power failures, as well as comprehensive protections for communication abnormalities, grid abnormalities, temperature limits, battery reverse connections, over/under voltage, over/under current, and overcapacity.
Charging supports constant current (CC), constant voltage (CV), and constant current-constant voltage (CC-CV) modes. Discharging supports constant current (CC) mode, with multiple configurable cut-off conditions including voltage, current, time, and capacity.
