In an electric vehicle, the battery management system receives circuit current signal changes returned from the CCS, reflecting the temperature changes in the batteries/cells. It then analyses and controls the work status of the battery pack to prevent the batteries from overheating and overcooling.
When it does, the BMS should turn off the battery pack to stop it from further charging and getting even hotter. Once the battery cells cool down and return to a temperature within the SOA, the BMS should allow charging to resume.
Connectors: To link the batteries together. They maintain the electrical flow and balance the load across all cells. Housing/Casing: This protects the internal components from physical damage and environmental factors. Battery packs work by connecting multiple individual cells in series or parallel to increase voltage or capacity.
Just as it measures the temperature, the BMS regularly measures the voltage of the battery pack's cells. If the cells are charged or discharged beyond the voltage SOA, the BMS should turn off the battery pack. The current SOA defines the range of positive and negative currents between which the battery pack must operate.
