When battery or cell imbalance occurs, there are several ways to address the issue, either using specialized tools or manual methods. Here are some effective solutions: A Battery Management System (BMS) is designed to monitor and balance the voltage across individual cells in a battery pack.
The imbalance in the cells can be averted through maintenance and monitoring that reveal how to prolong the life of the battery pack you have for your EV. Driven by the above-discussed factors, it is recommended that battery balancing should be done once a year or after each 10000 to 15000 miles.
Here's why battery balancing is so important: Variations among battery cells in series and parallel setups reduce the system's usable capacity. For example, in a 500 kWh system with 50 series cells, each storing 10 kWh, if one cell reaches only 85% state of charge (SoC) while others are at 100%, the pack's stored energy drops to 495 kWh.
