-
Energy price: Check your electricity bill for the current energy price, which is usually listed in cents per kWh. For example, if your rate is 15 cents per kWh, you would use 0.15 for calculation.
-
Cost calculation: Substitute the values into the cost formula. Using our example, if the battery capacity is 1.2 kWh and the energy price is $0.15 per kWh, the calculation would be:
– Cost = 1.2 kWh × $0.15 = $0.18.
This means it would cost approximately 18 cents to fully recharge the battery from empty. -
Efficiency factor: Consider an efficiency factor for the charging process. Charging is not 100% efficient due to energy loss in heat. Typically, charging losses range from 10% to 20%. To accommodate for this, you would adjust your capacity. For example, for a 1.2 kWh battery and a 15% efficiency loss, the required energy would be 1.2 kWh / (1 – 0.15) = 1.41 kWh. The new cost would then be:
– Cost = 1.41 kWh × $0.15 = $0.22.
By considering battery capacity, energy price, and efficiency, you can accurately calculate the cost of recharging a battery.
