The Design of Insulation Monitoring Device for Electric Vehicle's Battery Pack

Abstract

A novel insulation monitoring method which can monitor the insulation resistance between both the positive and the negative electrode of the electric vehicle's battery pack and the vehicle's body is proposed. The insulation monitoring method proposed in this paper is deduced theoretically, and the hardware and software design of an insulation monitoring device based on this method is given. The experimental results prove the correctness of the insulation monitoring method and the practicability of the insulation monitoring device.
