You have to remember the law of conservation of energy. An 80% charge in 5 minutes of a 75 kWh battery (regardless of battery type or chemistry), would require a 720 kw charger. At residential 240Volt that is 3,000 amps. Further down the article it mentions a 10-minute version with a 400kW charger.. That's 1,667 amps. Anybody on here have 1,700 amp service at their house? Trust me I'm all for more electric cars being sold (I'm the plant manager of a coal-fired power plant), but the misinformation being thrown out there about battery life, charging times and the practicality of a nationwide charging system in just a few years is abject nonsense. Personally, I would indeed like to get one, then I can put a bumper sticker on the back that says "this car is coal powered" |
