# The Cost Of Charging An Electric Car

It is hard to figure out the exact charging cost of an electric car. You have to calculate quite a complex number to get a real idea of the charging cost of an electric vehicle. Here we are explaining how to work it out.

**Figure out the pence per kWh**

While calculating the cost of charging an electric car, first of all, you have to consider the pence per kilowatt-hour (kWh) likewise pence per liter for a traditional fuel car. It will help you to identify the electricity costs used to fill up your vehicle. The energy supplier will use kWh as a standard measurement to bill you. For example, if you utilize 1,000 watts of electricity for 1 hour, you have to pay for this. Usually, our home electricity bills are calculated in this way. On average the home electricity bill stays between 10-14 pence. If the petrol is 128p per liter, the electricity bill will be between 10-14 pence per kWh.

**Identifying the size of the battery**

The next step is to consider the size of the battery which indicates the measurement of capacity. If you compare it with a petrol car, we can understand it easily. If a petrol car has a 40-liter tank, the cost to fill it up is £51.20. Because per liter petrol rate is £1.28. Similarly, the size of the battery of an electric car indicates how many kWh of energy it can store. The larger the capacity the bigger the charging cost. The Tesla model s 100d is the largest battery size currently available in the market. The cost to the charge of this 100-size battery would be £10.00 assuming the price per kWh is 10 pence.

**Calculating per mile cost**

Furthermore, the cost to charge for Nissan Leaf 30 size battery at 10 pence per kWh would be £3.00 while it is £0.70 for BMW i8 battery size 7 and £0.70for Mitsubishi Outlander battery size 12 would be £1.20.

Till now we have calculated the pence per mile cost. If we want to identify the cost per mile, we have to divide the cost by distance. If the real-life range is 120 miles for Nissan Leaf 30kWh, the cost per mile would be £0.025 for this particular model.
