2. How much does it cost to charge an electric car at home?
As one would expect, not only is charging of an electric vehicle extremely more convenient than a conventional fuel powered vehicle, Electric Cars are also much cheaper compared to the cost of petrol or diesel.
To calculate the cost of charging an electric car, you must first know, 1) the rate of fuel consumption for your electric vehicle in kilowatt-hours (kWh) per 100 miles, and, 2) the cost of electricity per kWh. For instance, if the cost of electricity is £0.1 per kWh and the vehicle consumes 30 kWh to travel 100 miles, the average cost would be about £0.03 per mile. However, the exact cost of charging an electric car also depends on the size of the battery which is being charged.
According to the national average of the United Kingdom, fully charging an electric vehicle would only cost about the same as it would cost running a central air conditioner continuously for five or six hours. Estimates released by General Motors indicate that the annual energy consumption of a Chevy Volt is about 2,500 kWh, which is even less than what the energy required for running a typical water heater for a year.
Another factor which determines the cost of charging your vehicle at home is the time of day you choose for charging. In certain parts of the world, that are special off-peak rates for electricity consumption during a certain time of the day, usually at night. If you have this facility at home, you should charge your vehicle during the specified off-peak hours, so that your costs for charging is further reduced. Some electric power supply companies also offer special discounted rates for electric car charging. You should check with your local electric power supply agent for details of any such offer which might be available in your area.
