The BMS consistently tracks the charge/discharge activities of the battery pack and monitor cell voltages. This data is useful for for determining if the battery is drained, for sustaining passive cells balancing and for ensuring that the high-voltage area is responsible for the voltage and total voltage detection of a single battery, insulation detection, relay adhesion detection, hi... https://www.amphenol-cs.com/product-series/hvlock-high-voltage-platform.html
