Title:
ELECTRIC VEHICLE DUAL-MODE CHARGING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/179289
Kind Code:
A1
Abstract:
Provided are an electric vehicle dual-mode charging system and method, comprising a DC wired charging loop and a wireless charging loop, wherein, the DC wired charging loop comprises a charging connector (1), a ground auxiliary power supply (2), an AC/DC module (3) and a ground communication control unit (CSU) (4); the wireless charging loop comprises a transmitting device (5), a receiving device (6), a ground transparent transmission module (7), a vehicle-mounted transparent transmission module (8), a vehicle-mounted communication control unit (IVU) (9), a vehicle-mounted auxiliary power supply (10), the AC/DC module (3) shared with the DC wired charging loop, and the ground communication control unit (CSU) (4). During the wireless charging process, the vehicle-mounted communication control unit (IVU) (9) simulates the wired charging process to supply power to a battery management system (BMS) and transmit a charging connection signal, and the battery management system (BMS) communicates with the ground communication control unit (CSU) (4) in a transparent transmission mode. Since the communication data is not processed in the transparent transmission mode, communication of the wireless charging mode can be implemented by using the communication protocol standard of the wired charging mode, thereby solving the problem of compatibility between wireless charging and wired charging, simplifying the communication mode, and reducing the difficulty and cost of implementing the dual-mode charging system.
