Problems solved by technology
[0002] At present, the voltage of the battery power system on electric vehicles usually exceeds the safe voltage that the human body can withstand, and objective factors such as insulation aging, wading, and rain will further reduce the original insulation resistance, so that in the process of use or maintenance, It brings danger of electric shock to users and maintenance personnel. Therefore, it is necessary to develop a vehicle-mounted real-time, high-efficiency, and low-cost electric vehicle power battery system insulation detection and control device.
