Abstract
A vehicle charging switching method. When a first charging circuit is used to perform direct current charging on a power battery, before switching to a second charging circuit to perform boost charging on the power battery, a charging controller controls the first charging circuit to pre-charge a pre-charging unit in the second charging circuit, and upon detecting that a voltage of the pre-charging unit matches a voltage of the power battery, controls the second charging circuit to perform boost charging on the power battery. A vehicle charging switching system, a computer-readable storage medium, a charging controller, and a vehicle.
Claims13
A vehicle charging switching method, wherein a vehicle comprises a power battery, a first charging circuit, and a second charging circuit;
- the first charging circuit is suitable for direct current charging on the power battery;
- the second charging circuit is suitable for boost charging on the power battery;
- the method comprising:
- when the first charging circuit is used to perform direct current charging on the power battery, if determining that it is needed to switch to the second charging circuit to perform boost charging on the power battery, controlling the first charging circuit to pre-charge a pre-charging unit in the second charging circuit;
- and
- upon detecting that a voltage of the pre-charging unit matches a voltage of the power battery, controlling the second charging circuit to perform boost charging on the power battery.
A vehicle charging switching system, comprising:
- a first charging circuit and a second charging circuit, wherein the first charging circuit is suitable for direct current charging on a power battery in a vehicle, and the second charging circuit is suitable for boost charging on the power battery;
