Abstract

The invention provides a connecting structure of a high-voltage electrical apparatus interlocking circuit of a pure electric vehicle. The connecting structure comprises a whole vehicle controller, an MSD maintaining switch, a motor controller positive electrode pluggable unit, a motor controller negative electrode pluggable unit, a battery pack positive electrode pluggable unit, a battery pack negative electrode pluggable unit, a converter pluggable unit, a battery charger pluggable unit, an air conditioner pluggable unit, a high-voltage steering pluggable unit, an electric warmer pluggable unit, a converter device, a battery charger device and an air conditioner device, and a main interlocking loop and an auxiliary interlocking loop are formed. The invention further provides a control method of the high-voltage electrical apparatus interlocking circuit of the pure electric vehicle. According to the connecting structure and the control method of the high-voltage electrical apparatus interlocking circuit of the pure electric vehicle, under the premise that I/O detection interfaces of the whole vehicle controller are limited, the connecting reliability of high-voltage harnesses can be monitored, and the user safety of the pure electric vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a connection structure and a control method of a high-voltage electrical interlock circuit of a pure electric vehicle. Background technique [0002] A pure electric vehicle refers to a vehicle powered by an on-board power supply, driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. It involves many high-voltage and high-current components, and its safety is the most important thing people pay attention to. At present, many pure electric vehicles do not have the high-voltage interlock protection function. When high-voltage connectors are disconnected or in poor contact, it is easy to cause high-voltage line leakage or cause the entire vehicle to be charged with high-voltage electricity. On the other hand, there will be a danger of personnel operating with electricity. Therefore, the high-voltage wiring harness and plug-in c...
