| 摘要 |
Implementations of the present disclosure involve a method and/or system for charge balancing across one or more modules or cells of a large battery system. In one embodiment to balance the modules, the battery management system may monitor the voltage output of the one or more modules of the battery system during recharging of the modules and compare the measured voltages to a set cutoff voltage. When one or more of the modules meets or exceeds the cutoff voltage, the battery system may activate an energy dissipating device associated with the one or more modules that meets or exceeds the cutoff voltage to reduce the voltage output from those modules below the cutoff voltage before the recharging signal is reapplied to the modules. Through multiple iterations of monitoring, charging and reducing the energy from the modules above the target, the SOC of each module becomes balanced near or at the cutoff voltage.
