WIRELESS CHARGING

| 2014-02-14 | 0 Comments

Toyota has announced verification testing is to begin later this month of a new wireless battery charging system it has developed for vehicles that use an electric powertrain.

The new technology allows a vehicle to be charged simply by parking it in alignment with a coil set into the surface of the ground. This makes the process simpler and easier, dispensing with cables and connectors. The charging system transmits electricity using magnetic resonance created by changes in magnetic field intensity between a transmitting coil in the ground and a receiving coil in the car. It is designed so that it can reduce any loss in power transmission efficiency caused by misalignment or height differences between the coils. To help the driver align the car correctly, Toyota has developed a function for its Intelligent Parking Assist system that shows the position of the transmitting coil in a parking space.

It will assess user satisfaction, the system’s ease of use, misalignment rates and charging behaviour. Toyota will use the test results to develop the technology further, with the ultimate aim of bringing the system to market. To help the driver align the car correctly, Toyota has developed a function for its Intelligent Parking Assist system that shows the position of the transmitting coil in a parking space. Toyota believes its commercialisation will help promote the use of electrified vehicles and mobility options that are smarter, easier to use and kinder to the environment.
