Overview of Battery Management Systems in Electric Vehicles
These parametric circuits regularly counter files the resistance between the high-voltage system and, therefore, the chassis. Typical guidance denotes the value must be greater than 100 Ω/volt for electricity (DC) systems (ISO 2011) . Thus, system should maintain a resistance above 35 kΩ between the high voltage system and the chassis.
