Abstract

The invention discloses a program controlled resistance coupling capacitance simulator. The program controlled resistance coupling capacitance simulator comprises a microcontroller, a multi-channel relay driver and a resistance coupling capacitance module, wherein the resistance coupling capacitance module comprises a multi-resistance adjustable resistance module and a multi-capacitance adjustable capacitance module connected in parallel, and the multi-channel relay driver drives a switching device in the resistance coupling capacitance module.

Description

technical field [0001] The present invention relates to the field of new energy vehicles; more specifically, the present invention relates to the high voltage safety of new energy vehicles. Background technique [0002] With the rapid development of new energy vehicles, the safety problems brought by new energy vehicles are becoming more and more serious, including high voltage safety. [0003] New energy vehicles generally have a high-voltage battery pack inside, and the battery pack and the car body are isolated from each other to ensure that passengers will not get an electric shock. In order to monitor the insulation between the high-voltage battery pack and the vehicle body, the OEM will add an insulation detector to the new energy vehicle. This insulation tester measures the insulation resistance of the vehicle in a high-voltage environment. [0004] As we all know, for high-voltage systems, there is inevitably a coupling capacitance between the high-voltage battery ...
