PSDcast – What's Holding EVs Back from the Mainstream?

Co-CEO of NexGen Power Systems, Dinesh Ramanathan.

­Numerous factors are holding EVs back, namely range anxiety, lack of infrastructure, and adjusting to new norms, like possibly having to at least partially plan your day around a recharge (or not, if quick charge systems mature quickly). And on the line to discuss these matters is the Co-CEO of NexGen Power Sy
