Abstract
A power system may perform charge balancing for a vehicle. The power system may include a battery including a plurality of modules, each module including a cell and associated resistive circuitry. The system may also include at least one controller configured to, in response to a cell achieving a threshold voltage and/or SOC, activate the associated resistive circuitry for the cell and reduce a charge current applied to the battery to prevent the cell from acquiring additional charge.
