The Era Of Car Wireless Charging Is Coming Soon? US Ventures Develop Magnetic Resonance Charging Pads

- Oct 23, 2018-

According to the Smithsonian Institution magazine, sharing unmanned vehicles in the future can quickly transport passengers in cities without the need for parking lots, garages or even private vehicles. But how can these cars get the energy they need to work if there is no place to charge? Who will charge the robot car?

Alex Gruzen, chief executive of WiTricity, a US wireless charging startup, said: "There are no drivers in the car, and no one helps the driverless cars plug in the wires. They need to be able to be on demand, in the battery. Charge yourself when the battery is low.


Grussen received a patent for charging electric products using magnetic resonance technology in 2010. In the past 8 years, WiTricity's answer to the question of how to shift its business from developing consumer electronics and mobile phone chargers to powering cars is that the answer to the above question is that electricity can be transmitted through the air through a charging system integrated into the urban landscape.


To achieve its goals, WiTricity has partnered with BMW to launch the first consumer-oriented remote charging system for the BMW 530e iPerformance.


But Dominique Bonte, an automotive industry analyst at ABI Research, points out that the 530e is a hybrid. With a battery capacity of only 9.2 kWh, it can be recharged in a few hours using WiTricity technology, but with a cruising range of only 25 km.


Even though WiTricity is 90% efficient, wireless charging is still relatively slow, and the Tesla Model S with 100 kW or 75 kWh battery can take up to a full day with WiTricity's system. However, Gruson pointed out that the vast majority of electric vehicles do not need to be fully charged every night.
