Abstract

A vehicle charging system comprises a power battery, a first battery manager, a direct current converter, a whole vehicle controller and a storage battery component. The whole vehicle controller controls connecting or disconnecting of the direct current converter, so that a power battery starts to charge the storage battery component or stops charging the storage battery component. The storage battery component comprises a battery pack, a charging DC / DC and a second battery manager. During the process that the power battery charges the storage battery component, the whole vehicle controller controls connecting or disconnecting of the direct current converter according to battery state information uploaded by the first battery manager and the second battery manager, so that a power battery starts to charge the storage battery component or stops charging the storage battery component, the second battery manager monitors the state of the battery pack, the charging DC / DC is controlled to charge the battery pack, accordingly, the vehicle charging system can monitor the state of the storage battery component in real time, and effective management can be carried out on charging of the storage battery component.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a vehicle charging system and a charging method thereof. Background technique [0002] The battery is a very important component in the vehicle field. The battery directly affects whether the vehicle can be started normally and supplies power to the electrical equipment. When the vehicle is running, it will consume part of the battery power. If the battery is over-discharged, it will cause The battery is out of power, and the remaining power of the battery is lower than the starting power, which will directly cause the vehicle to fail to start next time, so the on-board battery needs to be charged. [0003] In the prior art, the storage battery does not have the function of battery management. During the charging process of the storage battery by an external power source, the storage battery may be overcharged or even damaged. Contents of the invention [0004] The tech...
