The pre-charge current dissipates power in the resistor. Each successive pre-charge adds more power so if the resistor has not cooled between operations then the temperature will rise. Frequent pre-charge operations will cause the temperature of the resistor to increase, potentially to the point where the resistor overheats and fails.

Large-capacity energy storage system (ESS) secure storage capacity by connecting batteries in parallel. When an ESS is fully charged, energy loss occurs due to passive cell balancing of the battery management system (BMS). A compensation current flows in from the batteries connected in parallel, and battery overcharge occurs. In …

Pre-charging introduces a new state in the system, which we will call the pre-charge state. In the pre-charge state, the pre-charge contactor and the HV negative contactor are closed as shown in Figure 2. The DC link capacitor charges to nearly the same voltage as the voltage source. After the pre-charge state, the precharge contactor opens …
