I just read that Mercedes Benz has a new electric vehicle, the AMG GT, which is capable of charging at a rate of 600 kilowatts (KW). To put that in perspective, a typical home with a 200 amp. 240 volt electric service, is 48 KW. The equipment required to charge a vehicle at that rate costs between $120,000 and $150,000, and installation costs another $200,000. Assuming the charger is supplied with 3 phase 480 volts, it would require more than 720 amps. The cable used to connect the charger to the vehicle must have a recirculating liquid cooling system to prevent it from overheating. Just that cable can cost $10,000. At $0.15 per kilowatt hour it would cost $90 to operate that charger for one hour.
