Abstract

The invention provides a charging device of a hybrid car. The charging device is suitable for being electrically connected with a first electric appliance and a second electric appliance. The charging device comprises a low-voltage storage battery, a high-voltage battery pack, a starting switch, a second charge control module and a first charge control module, wherein the starting switch is used for conducting the low-voltage storage battery at the first state to provide power for the first electric appliance, and conducting the low-voltage storage battery at the second state to provide the power for the first electric appliance and the second electric appliance; and the high-voltage battery pack is conducted to charge the low-voltage storage battery when the conditions that the voltage of the low-voltage storage battery is lower than the voltage of the pre-set battery, and the starting switch is at the first state or the second state are detected by the first charge control module, and the condition that the electricity of the batteries of the high-voltage battery pack is not lower than the electricity of the pre-set batteries is judged by the second charge control module. The invention further provides a charging method of the hybrid car. With the adoption of the charging device and the charging method provided by the invention, the excess use of the low-voltage storage battery can be prevented, and the non-recoverable damage can be prevented.

Description

technical field [0001] The invention relates to a car charging device and a charging method thereof, in particular to a hybrid electric car charging device and a charging method thereof. Background technique [0002] When the vehicle is locked and stationary, the controllers still operate, and the required dark current can be provided by the low-voltage battery. The battery capacity of the low-voltage battery of a traditional car is generally larger. This is because the car needs a low-voltage battery to provide current to start the engine during the starting process. As the model becomes larger, the engine displacement is also larger, so the current required by the low-voltage battery is also larger. , taking the 12V lead-acid battery as an example for the low-voltage battery, the battery capacity of the general mini-car is between 32-45Ah, that of a small car is between 42-60Ah, that of a medium-to-high-end large-displacement car is generally between 60-90Ah, and that of a...
