Abstract

The invention provides a battery charging control method and device and an automobile. The method includes: acquiring a status parameter of a battery, and according to the status parameter, acquiring an actual relationship curve for internal resistance and number of charging-discharging times of the battery within a preset time, which is a time interval from an automobile startup moment to a preset moment; comparing the actual relationship curve and a preset relationship curve; if the actual relationship curve is not in a preset range of the preset relationship curve, updating a preset charging quantity threshold of the battery; according to the status parameter, acquiring a quantity value of the battery; comparing the quantity value of the battery to the preset charging quantity threshold; according to comparison results, determining whether or not a generator charges the battery. The battery charging control method and device has the advantages that the preset charging quantity threshold of the battery is flexibly adjusted according to the status features of the battery, deep discharging of the battery is effectively avoided, the battery is kept running in the optimal state and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to battery technology, in particular to a storage battery charging control method, device and automobile. Background technique [0002] At present, with the development of energy technology, there are more and more types and models of on-board batteries available to car owners to choose from. [0003] Due to the wide variety of batteries, such as lead-acid batteries and AGM batteries, users will replace different types of batteries at will during use, which causes compatibility problems between the battery charging system and different types of batteries, resulting in deep discharge of the battery. Thereby affecting the working efficiency and service life of the battery. Contents of the invention [0004] The invention provides a storage battery charging control method, device and automobile, which can flexibly adjust the preset charging power threshold of the storage battery according to the characteristics of the storage batt...
