Abstract

The invention relates to the technical field of electric vehicles and discloses an electric automobile. The electric automobile comprises a frame and wheels arranged on the frame, the electric automobile further comprises a driving motor, a motor controller, a power battery and a vehicle control unit which are arranged on the frame, the motor controller is connected with the driving motor and controls the output of the torque and the rotation speed of the driving motor, and a motor overload protection module and a motor overheating protection module are further arranged in the motor controller; the power battery is connected with the motor controller, and the motor controller outputs the electric energy of the power battery to the driving motor; the vehicle control unit is connected with the motor controller and the power battery respectively and outputs control signals to the motor controller, and the motor controller controls rotation of the driving motor. According to the electric automobile, the battery changing manner is simple, the battery can be pulled out from the side surface directly, manual operation of parking is eliminated completely, operation convenience and comfort are improved, a wheel frame is adopted so that the initial position of the bottom surface of a warehouse is reduced to be below the center positions of tires, and the whole vehicle controllability and the stability are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle. Background technique [0002] Compared with internal combustion engine vehicles, electric vehicles consume less energy and have lower pollution. It is the industry's technological development trend and an industry direction strongly encouraged by the state. However, the vast majority of electric vehicles currently on the market are developed based on the body of an internal combustion engine vehicle, with heavy weight, large battery, high cost, low energy efficiency ratio, and inconvenient charging and discharging. Contents of the invention [0003] Aiming at the disadvantages of high cost, low energy efficiency ratio and inconvenient charging in the prior art, the invention provides an electric vehicle with low cost, high energy efficiency ratio and convenient charging. [0004] In order to solve the above technical problems, the present inventi...
