A kind of spare battery case of electric vehicle and electric vehicle

Abstract

The invention provides a spare battery box for an electric vehicle and the electric vehicle. The spare battery box for the electric vehicle is installed between the frame and the seat of the electric vehicle, and includes a box shell, which houses a lithium battery. The box housing includes a top cover and a bottom cover that are arranged oppositely, the bottom cover is provided with a number of box fixing feet that can be fixed to the vehicle frame, and the top cover is provided with a number of fixing grooves for the vehicle seat. The seat fixing feet of the electric vehicle are inserted and fixed, and a charging and discharging interface is also provided on the box shell, and the lithium battery is connected to the electric vehicle's in-vehicle circuit through the charging and discharging interface to supply power for the electric vehicle, or through the The charging and discharging interface is connected to an external power source to charge the lithium battery. The beneficial effect of the invention is that the running distance of the electric vehicle can be effectively extended, and the height of the seat can be raised, and the structure is simple and easy to use.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle spare battery box and the electric vehicle. Background technique [0002] Electric vehicles are a commonly used means of transportation. Because of their low cost, small footprint, energy saving and environmental protection, they are deeply loved by consumers. However, due to the limited capacity of batteries carried by electric vehicles at present, the driving distance of electric vehicles is limited, which is generally not long, so when the electric vehicle is out of power, the rider needs to find a charging point for charging, which is not only inconvenient, but also wasteful. time. [0003] Electric cars are usually smaller and lighter, and their seat heights are generally non-adjustable, so they are suitable for small people. For larger people, the use of electric cars will feel restrained, so the use of electric cars is limited. Contents of ...
