1results about How to "Protect the charging process" patented technology

The application relates to a charging method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: after determining that a charging interface of a backup battery establishes a connection, determining whether the backup battery can be charged according to a vehicle initial ignition state, an initial temperature of the backup battery and a pre-configured temperature condition range; in the case of determining that the backup battery can be charged, acquiring a voltage of the backup battery and a duration of the vehicle ignition state; determining a charging mode of the backup battery according to the voltage of the backup battery, a pre-configured voltage condition threshold and the duration of the vehicle ignition state, and controlling the charging of the backup battery according to the charging mode, wherein the charging mode comprises a constant current mode or a trickle current mode; and determining whether to stop charging the backup battery according to the charging mode and the pre-configured temperature condition range. The method can reduce the performance loss of the backup battery and is beneficial to improving the service life of the backup battery.
