Canadian-based Electra Meccanica (EM) has selected 5606 Ricardo to integrate a wireless electric vehicle charging system from 213 Qualcomm into a planned autonomous version of its one-seater Solo electric vehicle (EV). The project aims to enable self-driving vehicles to be an option for future mobility services.


Qualcomm's Halo system uses resonant magnetic induction to transfer energy wirelessly from a ground-based pad to one integrated within the vehicle. It is then used to recharge the battery while aiming to remove the need for user interaction with infrastructure or cables.

Halo features a high misalignment tolerance, allowing it to support high and low road clearance vehicles such as sports utility vehicles and roadsters, with the pad installed either on the road, flush mounted or buried beneath the surface. In addition, the proper alignment of the charging pads is indicated through a positioning system, which is said to remove the need for precise parking.

EM is currently developing its Solo EV. The highway capable commuter car will come with three wheels and a 100-mile range via its 7.3 kWh Li-ion battery pack.

Paul Rivera, Ricardo's president, said: “Ricardo is pleased to have been asked to assist Electra Meccanica with the integration of the Qualcomm Halo wireless EV charging system on the Solo vehicle. 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.”

    Options abound for road weather sensing
    Meteorological organisations invest millions in super-computers to crunch data for ever-more accurate forecasts but inherent unpredictability means that other methods of alerting drivers and road authorities to fast-changing weather and highway conditions are essential. For years, static weather sensors to measure factors such as surface water, ice or high roadway temperatures have been embedded in highways to provide such data. But that is changing.
