Wireless Charging Moving Forward
Wireless charging will contribute to mass-market production of electric vehicles by automakers and their suppliers, according to a webinar presented by Qualcomm Halo. Keith Malinson, an industry analyst with WiseHarbor, and Anthony Thomson, vice president of development and marketing, Qualcomm Halo, gave a presentation on the technology innovations bringing wireless electric vehicle charging (WEVC) to market.
While wireless charging has been in application since the 1990s, technology barriers for acceptance by OEMs are being resolved, the speakers said. Improvements including Double-D and BiPolar coil topologies have significantly increased power transfer, better positioning tolerance, less mass and size, and have dropped down in costs.
Concerns over the safety of using wireless charging are being addressed by Foreign Object Detection (FOD) and Living Object Protection (LOP) systems. That can come through an animal, such as a dog, being under the electric car during charging. Excessive heating of stray objects which are energized by the inductive power transfer between the base and vehicle pads run the risk of causing skin burns or fire. The best FOD and LOP systems now conform to regulations which make WEVC safe, and are reliable including minimizing false alarms and missed detections, Malinson said
Timetable on WEVC
Automakers are seeking proposals from technology suppliers on wireless charging systems for their electric vehicles, Thomson said. Advanced engineering departments are examining offerings on the market and their costs in manufacturing production cycles. It’s likely that WEVC will be offered by automaker electric vehicles as a charging option in late 2017 for the 2018 model year, he said.
Automakers and charging suppliers are looking at the benefits WEVC can bring to mass-market adoptions of EVs. “It’s all about the user experience. A plug in can be a hassle when plugging in to charge and later having to unplug,” Thomsan said.
In the next few years, technology innovations may be integrated with using WEVC, Malinson said. Automated charging in carsharing programs and with self-driving cars could assist in acceptance of WEVC and EVs.
