Tesla effect heating car wireless charging program at a glance

Tesla (TSLA) said that the German Federal Automobile Transport Agency had completed an investigation into the fire on the Tesla Model S car and found no problems related to the manufacturer. Tesla shares soared 16.53%. Investment bank Jeffrey believes that Germany’s positive findings mean that Tesla can also avoid cars being recalled for Security reasons in the United States.

Car wireless charging is still the focus of everyone's attention.

Although plug-in electric vehicles still have their advantages, some technology suppliers still believe that not all electric vehicles like plug-in charging solutions, and some car manufacturers want wireless charging technology. Lacy Heiberger, marketing manager for Evatran, a provider of automotive wireless charging solutions, said: "We are currently negotiating with many car manufacturers interested in wireless charging technology."

At present, the market for wireless charging for vehicles is still very small and progress is slow. A few car manufacturers are still conducting internal research and development, and some car manufacturers are still discussing cooperation with technology suppliers. According to a prediction made by RnRMarketResearch.com, the car wireless charging market will be approximately $4.6 billion by 2019.

The following is a series of wireless charging solutions developed for electric vehicle (EV) applications, and some are wireless charging solutions developed for in-vehicle consumer devices; let's see if they have potential for growth!

Evatran socket-free vehicle charging system

Developed by American manufacturer Evatran, the Plugless wireless charging system uses inductive technology to wirelessly charge vehicles; their solution is to use the vehicle adapter Vehicle Adaptor on the vehicle chassis and the platform on the ground. When aligned, the entire system is woken up and automatically transmits energy through an air gap equivalent to the Level 2 charger.

Evatran's Plugless system provides guidance so that the driver can more quickly align with the charging device while parked, and the system is also compatible with the vehicle's existing software; therefore, although it is wirelessly charged, the vehicle actually thinks it is "plugged in" Electricity". The system has been tested with partners through actual testing and is immediately available to consumers for installation on electric vehicles such as the Nissan Leaf or Chevy Volt.

HEVO Power on-road vehicle charging station

HEVO Power, also from the United States, plans to install wireless charging stations on the roads, allowing electric trucks and electric mass transit vehicles to wirelessly charge at certain parking spots.

The road wireless charging station device developed by HEVO is a bit like a manhole cover on the road; the electric car is loaded with a receiver that can be charged at 10 kW, even higher than some wired charging solutions.

Bosch's car wireless charging system

Automotive electronics supplier Bosch also has a car wireless charging solution from Evatran; the system includes an in-vehicle control panel with electronic components and hardwired to a dedicated 240V cable. The system also includes a Vehicle Adaptor with a receiving coil and a parking pad that delivers power.

Rail type electric vehicle charging system

In 2012, Stanford University proposed an idea to use electric coils mounted on rails to power electric vehicles in motion.

Wireless charging solution for in-vehicle devices

Also used in cars, Delphi Automotive has developed a wireless charging system for in-vehicle mobile devices. The system (Wireless Charging System for Consumer Devices) has no wiring or plugs, but a magnetic field that is transmitted through a resonant source. To provide power, you can charge wireless headsets, smart phones, tablets and other devices.

In cooperation with Powermat Technologies, General Motors (GM) is also developing wireless charging systems for mobile devices used in the car; GM's Chevrolet, Buick, Cadillac and other brands can use the system.
