[0002] Electric vehicles are one of the most popular car models among urban office workers at present, especially two-wheeled electric vehicles, which are energy-saving, environmentally friendly, easy to charge, safe at low speed, economical and affordable, small in size and light in weight, and can freely shuttle through streets and alleys. In congested urban roads, electric vehicles are not afraid of traffic jams, and parking is convenient without occupying too much public space. Electric vehicles have become the best choice for going out to work and buying groceries.

[0003] At present, due to the rapid development of society, the brands of electric vehicles are also increasing, and due to the rapid development of take-out and express delivery, the batteries of electric vehicles have also undergone rich changes.
