Wireless Charging System
Simple, smart technology that changes the concept of charging and parking
This system frees an electric vehicle (EV) of the need for a cable when charging, further advancing the convenience of EVs for charging at home or work. As the car can be parked always in a designated location, the steering can be operated automatically, greatly reducing the hassle of parking.
Technology Functionality
Parking misalignment is minimized by combining the Advanced Parking Assist with the EV Wireless Charging System, which changes the efficiency of charging as per the parking location. An EV can always be charged at maximum efficiency.
Wireless Charging System
When charging an EV there is no need for a charging cable, with the vehicle charged just by parking at a predetermined location.
Advanced Parking System
The steering operates automatically in conjunction with designating the parking location on the screen of the navigation system (Around View Monitor), and giving guidance on moving forward or reversing. The driver can park the vehicle in the target location just by operating the accelerator, brakes or shift according to the guidance.
Technology Configuration
Magnetic flux is generated vertically from the ground when electricity passes through the Ground Transmission Unit’s primary coil, which is installed on the surface of the parking place. Electrical pressure is generated by overlapping with the secondary coil in the Vehicle Receiver Unit in the vehicle, and electricity is supplied from the first coil to the second one (electromagnetic induction). The unique technology achieves a charging efficiency of 80-90%, equivalent to that of cable charging.
The Advanced Parking Assist harnesses the technology of the Around View Monitor. It understands the situation of the vehicle surroundings and sets a target position using four high-definition cameras to the front, back, left and right of the car, calculating the necessary processes until parking is complete. Along with displaying guidance on moving forward and reversing that matches the calculated processes, and then prompting the driver’s operation of the vehicle, it automatically controls the steering using the actuator.
