Abstract

The invention relates to the technical field of battery protection, and discloses an idle-speed-based lithium battery protection method, device and equipment and a storage medium, and the method comprises the steps: calculating the current rotating speed of a BSG motor through a preset power calculation strategy when the current driving working condition of a target vehicle is idle speed; when the first output current of the target lithium battery is larger than a preset current threshold value and the electric quantity SOC of the target storage battery is smaller than a preset safety threshold value, the current rotating speed of the target engine is adjusted through the target output power based on the generated power; when the current driving working condition is the idle speed, the first output current of the target lithium battery is larger than the preset current threshold value, and the electric quantity SOC is smaller than the preset safety threshold value, the target lithium battery is protected by adjusting the current rotating speed of the target engine; compared with the prior art, a BSG motor is replaced by a motor with higher power, so that the lithium battery is prevented from discharging, the risk of power shortage of the lithium battery can be effectively reduced, and the improvement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of battery protection, in particular to an idle speed-based lithium battery protection method, device, equipment and storage medium. Background technique [0002] With the continuous development of lithium battery technology, lithium batteries as a new type of green energy have been more and more widely used, and have gradually replaced batteries such as lead-acid batteries as the power source of vehicles. The reasons for the replacement of lead-acid batteries are: lead Acid batteries contain harmful heavy metal substances such as cadmium, lead, mercury, large volume, heavy weight, short service life of lead-acid batteries, and large power attenuation under low temperature conditions, so that lead-acid batteries have to be eliminated, and lithium batteries have to be eliminated. The battery solves these disadvantages of lead-acid batteries very well, but with the extensive use of lithium batteries, the probl...
