Abstract

The invention provides an insulation device method and device for vehicle. The method comprises the following steps: adjusting the capacitance of a Y capacitor connected to a position between a high tension loop and a chassis ground; detecting the insulation situation of the high tension loop through an insulation monitor connected with the high tension loop of the vehicle after each adjustment; determining the allowable value of the Y capacitor corresponding to the insulation monitor according to the insulation situation of the high tension loop. The method can effectively reduce the problemtroubleshoot cost and part rectification cost after vehicle insulation problems occur.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle insulation design method and a vehicle insulation design device. Background technique [0002] As the country pays more and more attention to environmental issues and vigorously advocates energy conservation and emission reduction to reduce environmental pollution, the automobile industry has created new energy vehicles in response to the country's environmental protection policies. [0003] Compared with traditional vehicles, the typical feature of new energy vehicles is the addition of high-voltage circuits for the entire vehicle. The existence of high-voltage circuits requires new energy vehicles to meet the safety of vehicle electricity consumption, that is, they must have the function of vehicle insulation monitoring. When new energy vehicles When there is a vehicle insulation failure alarm problem, there will be a problem of high cost of troubleshooting and probl...
