Abstract: In view of the high precision requirements for energy storage battery cell voltage sampling and battery cluster voltage, current, and insulation detection, this paper presented a liquid cooled battery management system based on ADBMS6830, which uses ADI's advanced AFE ADBMS6830 and TI's precision ADC ADS1120 to achieve accurate measurement of battery voltage information, cluster voltage, cluster current, and system insulation impedance detection. The test results show that the battery voltage acquisition can achieve measurement errors within±2 mV within the full temperature range of standard voltage 3.3 V, cluster voltage acquisition can achieve testing accuracy of±0.06%, cluster current acquisition can achieve testing accuracy of ±0.06%, and insulation detection can achieve testing accuracy of ±5%. The proposed liquid cooled battery management system has been applied in a series 5 MWh liquid cooled energy storage system, verifying the feasibility of the system.
