Abstract

The embodiment of the invention discloses a charging method and device, a charger, a battery and a storage medium, and the charging method comprises the steps: obtaining an overcurrent protection threshold value of a second battery when a pre-shutdown instruction sent by a first battery is received, and the second battery is a battery, except the first battery, in the batteries charged by the charger; determining a target charging current value of the charger according to the overcurrent protection threshold value; and setting the target charging current value as an output current value of the charger. According to the embodiment of the invention, the battery can send the pre-shutdown instruction to the charger, and the charger can set the output current value according to the overcurrent protection threshold value of the remaining second battery, so that the current value output by the charger before the first battery is shut down is smaller than the overcurrent protection threshold value of the remaining second battery. After the first battery is shut down, the situation that the second battery stops charging due to overcurrent protection is avoided, and it is guaranteed that the remaining second battery can be normally charged.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of charging, and in particular to a charging method, device, charger, battery and storage medium. Background technique [0002] As a common power source, batteries are widely used in plant protection equipment such as drones and unmanned vehicles. The batteries need to be charged with a charger. In order to improve the charging efficiency of the charger, the charger generally charges multiple batteries at the same time. [0003] When one-to-many charging is performed, multiple batteries are connected in parallel at the current output terminal of the charger. If one of the multiple batteries stops charging, the battery will be shut down directly. The charging current will be applied to other batteries, which may cause the charging current of other batteries to exceed the overcurrent protection threshold, triggering other batteries to stop charging, and continue charging other batteri...
