High voltage battery pack discharge current exceeds limit
Battery Charging and Discharging Parameters
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is ...

age limits for both charge and discharge. These charge and discharge current limits are then transmit-ted to other external devices digitally via CANBUS, via 0 to 5 volt analog signals, or via on/off outputs. The BMS also calculates the state of charge of the battery pack and monitors the state of health of the individual cells and battery pack.
