Improving EV efficiency and safety hinges on an effective Battery Management System (BMS).
For automotive BMS, it’s important to note that the battery pack is not directly connected to the motor.

Instead, it interfaces through relays and fuses. Any disconnection or abnormal connection between these components can lead to unexpected increases in impedance. Since the voltage and current flowing from the battery to the motor are substantial and fluctuate frequently, increased impedance can cause system temperatures to rise and become unstable.
