Description

Technical Field

[0001] The utility model relates to the technical field of battery-swap electric vehicles, and in particular to a battery compartment system for preventing live plugging and unplugging of battery-swap electric vehicles. Background Art

[0002] Electric vehicles use electricity as energy and are green means of transportation. Specifically, electric vehicles are equipped with battery packs, which provide power energy for electric vehicles. Since the electric energy stored in the battery pack of an electric vehicle is limited, the distance that an electric vehicle can travel without charging is limited. In order to enable electric vehicles to travel longer distances, there are currently some charging stations set up on the side of the road that are specifically designed to charge electric vehicles. The charging stations are similar to gas stations for ordinary cars. When the battery of an electric vehicle is exhausted or about to be exhausted, the electric vehicle can charge the battery in the charging station; when the battery is fully charged, the electric vehicle can continue to travel. However, when an electric vehicle is charged in a charging station, it takes at least one or two hours, and at most seven or eight hours. Long-term parking for charging will delay the normal use of the electric vehicle, especially for logistics electric vehicles, which will cause logistics work to be unable to proceed normally. Therefore, many logistics electric vehicles will choose to replace batteries to carry out endurance operations. Since the battery pack is detachably electrically connected in the battery compartment, the battery compartment door may suddenly open during vehicle driving, resulting in the live plugging and unplugging of the battery pack, which may cause burning of the battery connector and pose a certain safety hazard. Therefore, a battery compartment system that can prevent live plugging and unplugging of battery packs is provided for battery-swap vehicles to solve the above problem. Utility Model Content
