Engineers of the Occirrian laboratory conducted a demonstration of a 120 kW electric vehicle charging system, in which, thanks to the new design and adding a device with silicone carbide, 97% of energy transmission efficiency were able to achieve.
The new technology made it possible to increase the power of the energy flow of six times, compared to their past development. In parallel, they could achieve an indicator of efficiency comparable to traditional chargers. The tests were carried out with a 15 cm air gap between magnetic coils and battery power system.
In the process of operation, the system does not heat up and is completely safe, which reduces the loss of charge to a minimum. The device takes energy from the network and converts it into a high-frequency alternating electric current generating a magnetic field that can transmit power through a significant air gap. Immediately the field of how energy enters the battery, it becomes a constant current and accumulates.
Researchers seek to increase the capacity of the device in 350 kW and improve the technology of wireless charging electric vehicles while driving. The dynamic power system will automatically charge vehicles through lining installed under the road. However, this requires an increase in the power of such systems.
