Abstract

The invention provides a charging control method and device, and relates to the technical field of automobile electronics. The method comprises the steps: obtaining a first control instruction, switching on a first power switch, and controlling a charging module to be pre-charged to a first target voltage value according to preset first time; obtaining a second control instruction, switching on asecond power switch, controlling a DC conversion module to convert the first target voltage value of the charging module into a second target voltage value of the battery, enabling the charging moduleto be pre-charged to the first target voltage value firstly, and then increasing the voltage of the charging module to the second target voltage value through the direct current conversion module, sothe current surge at the moment of charging and switching on the battery can be effectively suppressed.

Description

technical field [0001] The present application relates to the technical field of automotive electronics, in particular to a charging control method and device. Background technique [0002] At present, in a vehicle hybrid system, a power converter is usually used to convert the voltage and current of the input terminal and the output terminal, so as to meet the power supply requirements of conventional electrical loads in the vehicle. [0003] In the prior art, during the conversion process of the power converter, the 12V DC power is generally converted into 48V DC power first, and then used to charge the 48V battery, but the moment the battery is connected, the battery will output a large charge. current, it is easy to cause damage to the battery or power converter. Contents of the invention [0004] The present application provides a charging control method and device, which are used to effectively suppress the current surge at the instant when the battery is charged wh...
