摘要： A battery module for an electric vehicle is provided. The battery module includes a case, multiple sodium-ion rechargeable battery cells, and an overcharge protection circuit. The sodium-ion rechargeable battery cells are stored inside the case and are connected in series. Each of the multiple sodium-ion rechargeable battery cells has a nominal voltage and a maximum voltage. The overcharge protection circuit has a voltage threshold for preventing an overcharging of each of the sodium-ion rechargeable battery cells. The voltage threshold is larger than the nominal voltage and smaller than the maximum voltage.

摘要： A battery module for an electric vehicle includes a case and a plurality of rechargeable battery cells stored inside the case and connected in series, wherein the plurality of rechargeable battery cells is stored in a parallel configuration inside the case in a plurality of rows, and at least one of the plurality of rechargeable battery cells is stored in each of the plurality of rows. The battery module further includes an overcharge protection circuit having a voltage threshold for each of the plurality of rechargeable battery cells to prevent overcharging. Each of the plurality of rechargeable battery cells has a nominal voltage and a maximum voltage. The voltage threshold is larger than the nominal voltage and smaller than the maximum voltage. All of the plurality of rechargeable battery cells are comprised of lithium iron phosphate LiFePO4, and a number of the plurality of rechargeable battery cells is five.
