Abstract

The invention belongs to the technical field of electric vehicles, and discloses a vehicle-mounted charging system and method. The system comprises a vehicle charging interface, a vehicle-mounted charger, a power battery and a vehicle control unit, when electric energy is accessed into the vehicle charging interface, a charging signal is sent to the vehicle-mounted charger; the vehicle-mounted charger sends a charging awakening signal to the vehicle control unit according to the charging signal; the vehicle control unit detects the state of the electric driving system when receiving the charging awakening signal, and sends a charging allowing command to the vehicle-mounted charger when the state of the electric driving system is a closed state; the vehicle-mounted charger outputs electricenergy to the power battery according to the charging allowing command; and the power battery receives the electric energy and charges according to the electric energy. By means of the mode, it is ensured that a vehicle cannot enter a drivable state in the charging process or when a charging cable is connected, and damage to the vehicle-mounted charging device or electric shock danger is avoided.The technical problem that potential safety hazards exist in an existing alternating current charging device is solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle charging system and method. Background technique [0002] With the expansion of the pure electric car market, the use of pure electric cars has become more and more frequent. An electric vehicle charging device is a device specially designed for charging the vehicle battery of an electric vehicle, and is a power conversion device with specific functions used to charge the battery. Electric vehicle chargers can be divided into DC charging devices and AC charging devices. [0003] The existing AC charging device is designed to meet the charging needs of the battery under different power levels by responding to the signal of the vehicle control system; the existing vehicle AC charging device has the disadvantage that the functions of the current vehicle charging device generally do not consider the user's usage habits, Charging safety cannot be guaranteed. For...
