The invention provides a battery module charging method and device, charging equipment and a readable storage medium. The battery module charging method comprises the following steps of: acquiring current charging information of a target battery module; determining a target three-dimensional matrix corresponding to the current charging information according to a corresponding relation between the charging information and the three-dimensional matrix, wherein the target three-dimensional matrix is obtained based on the temperature, the charging boundary value and the SOC value of the target battery module; and charging the target battery module based on the current charging information and the target three-dimensional matrix. In the battery module charging method, the target three-dimensional matrix comprises the charging boundary values of the target battery module at different temperatures and SOC values, so that the target battery module is dynamically charged based on the charging boundary values, and the charging efficiency is improved under the condition that the service life of the target battery module is not damaged.
Description
technical field [0001] The present application relates to the field of battery charging, and in particular, to a battery module charging method, device, charging device, and readable storage medium. Background technique [0002] As the application scenarios of new energy batteries become wider and wider, the demand for new energy batteries is increasing. At present, when charging the battery, if a high current is used to charge the battery, although the charging time can be shortened, it may cause damage to the battery and affect the service life of the battery. If the battery is charged with a small current in a conservative manner, the charging time will be too long and the charging efficiency will be low. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a battery module charging method, device, charging device and readable storage medium, which can realize fast charging without affecting the service life of the b...
