Qualcomm Halo Wireless Electric Vehicle Charging No fuss, just wirelessElectric Vehicles set for growthThe use and acceptance of Electric Vehicles (EVs) amongstbusinesses and consumers will become more prevalent, drivenby investment from the automotive and infrastructure industries.Behind this growth, total cost of ownershipQualcomm Halo believes that wirelesswill be one of the key purchasing criteria, ascharging, which is simple and convenient, willwill the simplicity of charging. Qualcommeventually become the preferred chargingbelieves that the improved user experiencemethod for all EVs. That is why we aredelivered by wireless charging will enhancedeveloping our universal wireless chargingEV growth. Plug-in charging is far from simple;technology that can be deployed in allit is cumbersome, brings potential health,geographic areas. Simplicity and minimumsafety and reliability issues, especially atdriver intervention are key features that winstreet level, while public charging equipmentout time-and-time again, and we believeis open to damage from the environment,when these features are coupled with highvandalism, and is visually unappealing.power transfer efficiency, wireless chargingis a winning combination.“ It is relatively easy to muscle power across a gapwithout any consideration of the consequences.The real achievement is to understand the parametersat play and transfer that power effortlessly.”Nigel P.
