Abstract

The invention provides a control method and device of the electric quantity of a power battery and an automobile. The control method of the electric quantity of the power battery comprises the steps that the real-time state information and a real-time working command of the automobile are obtained; when the automobile is in the first state and the working command is a preset command, the output power of the power battery and the maximum output power of a range extender are obtained, specifically, the preset command is used for controlling the residual electric quantity of the power battery to be larger than the preset electric quantity range; when the output power of the power battery meets the first preset condition, the residual electric quantity of the power battery is obtained; and when the residual electric quantity of the power battery meets the second preset condition, the range extender is controlled to charge the power battery or stop charging the power battery. By the adoption of the control method of the electric quantity of the power battery, the situation that the residual electric quantity of the power battery is larger than the preset electric quantity in the long-term traveling state can be guaranteed, and accordingly the service life of the power battery is prolonged.

Description

technical field [0001] The invention relates to the field of charging electric power of a power battery of an automobile, in particular to a method for controlling the electric power of a power battery, a control device and an automobile. Background technique [0002] Extended-range electric vehicles have realized short-distance electricity consumption and long-distance oil-driven driving methods. Whether it is self-driving travel or work commuting, extended-range electric vehicles are one of the very good choices. However, it is inevitable that the range-extending system will not start for a long time during work and commuting. As we all know, the long-term non-starting of the range-extending system will reduce the life of the range-extending system; and when the power battery is fully charged or relatively low for a long time, the battery The lifespan will also be relatively reduced. During long-distance self-driving trips, the battery power of the car will inevitably be ...
