Charging Electric Vehicle Batteries: Wired and Wireless Power Transfer
Due to the environmental concerns about CO2-caused global warming, policymakers are pushing electrified vehicles (EVs) to reduce these emissions. For passenger vehicles only, the electrified fleet is forecasted to reach 80 million in the U.S. and 500 million globally by 2040. Key enablers for such rapid EV adoption include the improvement of battery energy density, lifespan and … [Read more...] about Charging Electric Vehicle Batteries: Wired and Wireless Power Transfer
