Application Area
Mainly used for testing battery modules such as pure electric engineering vehicles and energy storage power station batteries.
Functional Features
(1) High efficiency, low energy consumption, and electricity feedback to the grid;
(2) Using modular design, with clear structure and easy maintenance;
(3) Adopting a common DC bus design, automatic cycling of charging and discharging energy between different channels is achieved on the DC side;
(4) Using a multi-stage multi-point calibration method to achieve high-precision sampling across the entire range;
(5) Each channel is equipped with one CAN communication channel, which can read real-time information such as battery voltage, temperature, SOC, etc. inside the BMS;
(6) Constant current and constant voltage charging with seamless switching, no voltage or current surge;
(7) Scan the code to automatically bind the testing process, start the test automatically, and determine the test results based on the testing conditions.
(8) Powerful working condition simulation function, supporting the import function of road spectrum data and working condition files;
(9) Support DBC file import function, real-time display of custom variables such as battery voltage and SOC.
