The PBTS series multi-function BMS board testing machine is mainly used to testing the BMS board specifications is within the parameters which declared by the BMS board supplier, so as to provide a set of testing standards for the staff. It is suitable for power battery BMS board manufacturers and power battery pack manufacturers. The test functions are: 1) overcharge protection voltage 2) overcharge recovery voltage 3) over discharge protection voltage 4) over discharge recovery voltage 5) over discharge current protection 6) short circuit protection performance test 7) charging current protection 9) equalization opening voltage 10) equalization real-time current 11) BMS board total consumption 12) single section self consumption current 13) overcharge protection delay 14) over discharge protection delay 15) overcurrent protection delay 16) internal resistance
