Embodiment Construction

[0039] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0040] The charging characteristics of batteries are related to temperature. For example, when charging at low temperature, the battery is prone to cracking, which leads to battery safety problems, battery capacity increases with temperature, and the probability of thermal runaway is higher when charging at high temperature than at low temperature. Therefore, when charging the battery, not only the charging rate and charging safety need to be considered, but also the damage to the battery needs to be ensured to be small. Based on this, the present disclosure provides a battery charging method, device, medium, battery management system and vehicle.

Abstract

The present disclosure relates to a battery charging method, device, medium, battery management system and vehicle. The method includes: obtaining the current voltage, current temperature and current capacity of the battery in real time; determining the target charging rate of the battery according to the current voltage, the current temperature and the current capacity; The battery is charged. Since not only the current voltage of the battery, but also the current temperature and current capacity of the battery are taken into account when determining the target charging rate of the battery, the battery can be charged at a charging rate suitable for the current temperature and current capacity. In this way, the damage to the lithium battery can be reduced, the battery life can be prolonged, and the charging safety can be improved while ensuring the charging rate of the battery.
