Question: how much electricity to charge bmw i3?
Answer: For example if you drive 10,000 miles per year, and an average i3 driver gets 3.9 miles per kWh that is 2,564kWh per year or an average of 7kWh per day. Make that 7.7kWh to allow for charging losses again and your average daily i3 charge is 7.7 times your unit price.
