Abstract

The invention provides a battery charging method and device and a computer readable storage medium, and relates to the field of a battery. The battery charging method comprises the step of performing constant-power charging on the battery with a preset power to a charging ending voltage, wherein the charging ending voltage is higher than an ending voltage of the battery which is charged in constant current and constant voltage and is lower than an upper limit of the highest safety rechargeable voltage of the battery. With the battery charging method and device and the computer readable storage medium, provided by the embodiment of the invention, the lifetime of the battery for charging in constant power can be prolonged.

Description

Technical field [0001] The present invention relates to the field of batteries, and in particular to a battery charging method, device and computer-readable storage medium. Background technique [0002] In the current energy shortage situation, renewable resources such as wind and solar energy have been widely used in various fields as new energy sources. With the widespread use of new energy sources, batteries are also used in various fields as energy storage devices and power sources. [0003] Since the current converted from renewable resources such as wind energy and solar energy is often unstable, it is necessary to stabilize the current and voltage through the energy storage system before inputting electrical energy into the grid. At present, the electric energy converted into wind energy and solar energy can be stored in the battery, and then the battery outputs a stable current to the grid. In order to increase the service life of the battery, the battery can generally be...
