Inductive charging is taking off, with various carmakers and startups making it a reality. Swiss company Brusa Elektronik is one of the developers forging the way. After a successful series production with BMW, the company is determined to take it further.
Last July, BMW and Brusa teamed up to provide wireless charging for the 530e iPerformance. The charger’s capacity was 3.2 kW, allowing a 9.2 kWh battery to be charged in about 3.5 hours. Now, Brusa is working on what is technically a second generation series, learning from its first go round and expanding the division and team to improve its design.
Brusa’s second generation wireless charging is a modular system called ‘Frame’. This system will be able to charge electric vehicles with powers ranging from 3.7 to 11 kW, using only the one base plate and an adapted coil. The Frame system has improved electromagnetic capabilities and improved allowances for the integration of power electronics both inside the ground pad and the vehicle module, which saves both money and space.
The company’s first generation wireless charging, created in collaboration with BMW in 2018, was certified by TÜV Rheinland for its compliance with Wireless Power Transfer Norm IEC61980. But at the moment, it’s too early to tell when or if Brusa’s new Frame technology will make it to the market. Brusa’s main objective is to make convenient charging a reality, and we hope it succeeds.
