Charging at home is the least worrisome of all charging situations, because you can charge while you sleep and not care about how long it takes. Same with charging at shopping centres, restaurants, parks, hotels, etc., because you're going to spend the time doing the thing you went there to do anyway, regardless of whether you're charging or not.
The only time charging speed actually matters is when you're on a long road trip and need to keep moving. That's when you need a fast charging solution, like CHAdeMO or Tesla's Superchargers.
- graycat 9y agoCharging time: In the US, houses commonly have from the grid 100 A at 230 V. So, that is 100 x 230 = 23,000 W (Watts) or 23 KW (kilowatts). For an electric car with a 75 KWh battery, the charging time using all the house power would be 75 / 23 = 3.26 hours. Maybe the house needs also to use an electric stove, electric clothes dryer, air conditioning, a water pump, a microwave oven, some lights, etc. so wants to use only half the house power for the car charging in which case the charging time would be 75 / (23 / 2) = 6.52 hours. From a Google search, supposedly at https://www.tesla.com/models https://www.tesla.com/models is "With unparalleled performance delivered through Tesla's unique, all-electric .... will achieve the maximum charge rate of 11.5 kW for 75 kWh configured vehicles." Then the minimum charging time would be 75 / 11.5 = 6.52 hours. So, net, for an electric car, I'd be concerned about charging time. With a gasoline powered car, can fill up in a few minutes.
