The present invention provides a battery pack high-voltage isolation device, a control method and an electric vehicle. The battery pack high-voltage isolation device includes: a battery pack and a first maintenance module connected to the battery pack; the first maintenance module includes: a housing surrounded by a Form an accommodating space; a positive switch, a fuse, a locking bolt, a first positive connection terminal, a second positive connection terminal, a first negative connection terminal and a second negative connection terminal arranged in the accommodating space; when the positive switch moves Drive the fuse to turn on or disconnect the connection between the first positive connection terminal and the second positive connection terminal; so as to achieve the purpose of isolating the high-voltage system of the electric vehicle and prevent the voltage output by the battery pack from causing harm to maintenance personnel.
Description
technical field [0001] The invention relates to the field of high-voltage isolation of electric vehicles, in particular to a high-voltage isolation device for a battery pack, a control method and an electric vehicle. Background technique [0002] As the pollution of the environment becomes more and more serious, the use of traditional fuel vehicles begins to decrease gradually, and electric vehicles using clean energy have gradually become the focus of people's attention. [0003] Electric vehicles use battery packs to store electrical energy to power the vehicle. In order to make the electric vehicle have better power performance, not only the battery pack needs to have a larger capacity, but also the battery pack needs to be able to provide a higher voltage. [0004] While the high-voltage output of the battery pack provides power for the vehicle, there is a risk of electric shock for personnel; usually, during maintenance of electric vehicles, it is necessary to isolate ...
