A telling benchmark for electric vehicles is how inventors and investors approach the challenges around battery charging. On two legs of the Electric Road Trip, our reporter Peter Behr called on two ventures that are aimed at advancing how EVs are "refueled" with electrons.
Rhombus Energy Solutions, in Dearborn, Mich., is turning out high-voltage chargers for bus and truck fleets. This is the story of engineer Kent Harmon and his colleagues, who persisted for a quarter-century to build charging technology for big fleets. See the full-length story in Energywire.
And in Bozeman, Mont., our EV was refueled at a charger created by entrepreneur Bill Clem, whose industrial designs span surgical devices and snowmobiles. His custom-designed public charging units are going into hotel and retail outlets, and into two Harley-Davidson dealerships that are offering the LiveWire electric motorcycle.
