Electra Meccanica’s SOLO EV to offer wireless charging capability

ABR Staff Writer Published 16 February 2018

British engineering consultancy Ricardo has been selected to assist Electra Meccanica with the integration of the Qualcomm Halo wireless electric vehicle (EV) charging system on the SOLO vehicle.

The Hybrid and Electronic Systems team at the Ricardo Santa Clara Technical Center will integrate the SOLO EV with a wireless EV charging (WEVC) system from Qualcomm. 

Qualcomm Halo WEVC technology utilizes resonant magnetic induction for transferring energy wirelessly from a ground-based pad to a second pad integrated within the vehicle.

The energy will then used for recharging the vehicle’s battery with no user interaction with infrastructure or cables.

Electra Meccanica general manager Ed Theobald said: “At Electra Meccanica, we believe the future of mobility will include autonomous driving options, so we felt that it was important to start engineering those capabilities for SOLO now.

“Induction charging is also a new technology we want to provide, and Ricardo has helped drive the integration of the Qualcomm Halo system for SOLO.”

Electra Meccanica's SOLO single passenger all-electric vehicle is a three-wheeled, highway capable commuter car with a 100-mile range provided by its 17.3 kWh Li-ion battery pack. 

At present, recharging is done by wire through a J1772 Universal Connector using a standard North American 110V or 220V AC electrical supply.

Electra Meccanica plans to include Qualcomm Halo WEVC technology because it is claimed to have a high misalignment tolerance, both vertically and horizontally. This enables it to support vehicles with high and low road clearance including SUVs and roadsters.

It is also claimed that the charging will work even if the ground-based pads are installed on top of the road, flush mounted or even buried beneath the surface.

The EV-maker stated that the new technology has the potential to revolutionize electric, plug-in and hybrid vehicle ownership experience and can reduce the inconvenience of plugging and unplugging on a daily basis.

Ricardo president Paul Rivera said: “Wireless charging of electric vehicles brings considerable benefits in terms of user convenience, avoiding the need to use cables or plug-in to recharge. We wish Electra Meccanica every success with the SOLO vehicle and its new wireless charging capability.”
