Abstract

A pure electric vehicle high-voltage distribution box cover opening monitoring system, including: a proximity switch installed between the high-voltage distribution box body and the box cover for detecting the opening state of the box cover and connected to a power supply, and one end connected to the proximity switch , the other end is grounded to the instrument panel display device, one end is grounded, the other end is connected to the buzzer alarm of the proximity switch and the vehicle controller connected to the proximity switch through the high-voltage maintenance switch, and the vehicle power unit is connected to the vehicle controller. When the proximity switch detects that the box cover is in the open state, the signal fed back is used as the input signal of the instrument panel display device, the vehicle controller and the buzzer alarm. The status is displayed, and at the same time, after receiving the signal input, the vehicle controller limits the power output of the vehicle power unit to achieve the reminder function that the maintenance switch is not disconnected.

Description

technical field [0001] The invention relates to a monitoring system for opening a cover of a high-voltage distribution box of a pure electric vehicle. Background technique [0002] At present, the high-voltage distribution boxes of pure electric buses are mostly arranged at the rear of the vehicle. When the vehicle is being unpacked for maintenance and other operations, some maintenance personnel forget to turn off the maintenance switch, or the driver cannot find the maintenance personnel behind in time. Starting the vehicle directly will cause electric shock or casualties, and there is a huge potential safety hazard. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a monitoring system for opening and monitoring the cover of the high-voltage distribution box of pure electric vehicles, which is simple in structure, easy to assemble, strong in reliability and high in safety. [0004] The tech...
