The invention provides a charging control system and method for an electric vehicle and the electric vehicle. The charging control system comprises a first wheel motor secondary side resonant network,a second wheel motor secondary side resonant network and a wheel motor power supply control device, wherein the first wheel motor secondary side resonant network is used for receiving battery power supply information provided by a vehicle-mounted primary side resonant network in an overground vehicle-mounted battery wireless charging system, and / or the second wheel motor secondary side resonant network is used for receiving power grid power supply information provided by a ground primary side resonant network in an underground power grid wireless charging system; the wheel motor power supplycontrol device is used for performing conversion processing based on the battery power supply information and / or the power grid power supply information to obtain a working power source required by awheel motor of the electric vehicle. Through the four-wheeled wireless power supply drive, the wireless charging during the running process of the electric vehicle is realized, and the vehicle controlsafety is increased.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to a charging control system and method for the electric vehicle and the electric vehicle. Background technique [0002] As people pay more attention to environmental protection, energy-saving and environment-friendly electric vehicles are getting more and more attention and recognition. With the continuous development of the electric vehicle industry, more and higher requirements are put forward for the energy supply of electric vehicles. [0003] Currently, the main modes of charging electric vehicles are wired charging and wireless charging. However, the wired charging method has difficulty in daily maintenance, poor flexibility and safety. With the development of wireless power transmission technology, the wireless charging mode has gradually been applied to the field of electric vehicles, showing better flexibility and stability, and improving the safety of the charging syste...
