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.
