1. Laboratory-level performance: 24-bit ADC/DAC high resolution, low voltage can be as low as 10V, voltage accuracy 2/10,000, current accuracy 5/10,000, current response time less than 5ms, sampling frequency 10ms, high-speed pulse, do A necessary function for working conditions, with a pulse width of 100ms, which can truly simulate the actual performance of the battery pack under working conditions. 2. Each channel is equipped with a communication function, and the aging process monitors the battery pressure difference, temperature, etc., and for this function, our company will provide customers with different BMS communication docking services. 3. According to the performance of different battery packs of customers, our company will provide the design of the test plan in the future.
