Abstract

The invention provides an electric vehicle and a charging control method and relates to the technical field of batteries, wherein the electric vehicle includes a motor, a control device, a plurality of single batteries and a plurality of acquisition actuators. The control device is used for acquiring a voltage value of motor-output electricity when a braking request is received, determining a certain amount of the single batteries among the multiple single batteries according to the voltage value, and transmitting a control signal to the acquisition actuators corresponding to the determined single batteries such that the acquisition actuators control the determined single batteries to be charged by the motor-output electricity after their serial connection. Through the above arrangement, the problem of the prior art that charging for a whole power supply system via electricity generated by motor braking has poor effect can be solved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an electric vehicle and a charging control method. Background technique [0002] In order to achieve higher energy saving and emission reduction, pure electric vehicles or hybrid electric vehicles are widely used. Among them, the power supply system is the power source of electric vehicles, and its performance affects the performance of electric vehicles to a large extent. Generally, a power supply system is formed by combining multiple single cells in series and parallel. [0003] The inventors have found through research that in the prior art, in order to improve the utilization rate of energy, a method of converting kinetic energy into electric energy is adopted to consume the kinetic energy of the electric vehicle, thereby achieving the purpose of braking. However, there is a problem that the charging effect is poor because the electric energy generated by braking charges...
