In any electric vehicle, the battery is a strategic component. All electric vehicles (EVs) are equipped with a Battery Management System (BMS), which intelligently controls battery charging and prevents battery operation from exceeding safety limits. BMS can continuously monitor the battery pack during charging and discharging, and optimize performance by balancing the batteries within the battery pack, thereby improving battery life and capacity. While maintaining safety standards, the accuracy, performance, and reliability of BMS will depend on the components used in the system. The Yangtze River connector provides a series of compact and flexible high-performance vehicle grade connectors for these power circuit designs
