Abstract

The invention discloses an electricity protection method of a vehicle-mounted battery, a vehicle and a readable storage medium. The method comprises the following steps: monitoring the speed of the vehicle in real time, and judging whether the speed of the vehicle meets a first preset condition or not; if the speed of the vehicle meets the first preset condition, acquiring the charge state of the vehicle-mounted battery; judging whether the charge state of the vehicle-mounted battery meets a second preset condition or not; and if the charge state of the vehicle-mounted battery meets a second preset condition, performing operating in a high-speed power supply keeping mode. According to the invention, under the condition that the power of the engine and the driving motor is not increased, the high-speed running power protection capability of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method for maintaining power of a vehicle battery, a vehicle and a readable storage medium. Background technique [0002] In general, there are two sources of driving force for a hybrid vehicle: one is the drive motor and the other is the engine. In the prior art, there are three working modes of the engine: 1. Cooperate with the generator, the whole torque is used to generate electricity; 2. The whole torque is used to drive the vehicle; 3. Part of the torque is used to generate electricity; the other part of the torque is used to drive the vehicle. In order to improve fuel efficiency, the engine generally adopts the above-mentioned second working mode when driving at high speed. However, if it is in this working mode for a long time, it is impossible to ensure that the charge of the vehicle power battery is at a usable value, and if it is necessary to ensure the ...
