# Does charging a car battery use a lot of electricity?

Contents

If electricity costs \$0.13 per kWh and the vehicle consumes 33 kWh to travel 100 miles, the cost per mile is about \$0.04. If electricity costs \$0.13 per kilowatt-hour, charging an EV with a 200-mile range (assuming a fully depleted 66 kWh battery) will cost about \$9 to reach a full charge.

## Does a car battery charger use a lot of electricity?

Compared to a cell phone charger they use a lot. They use whatever they are designed to use. A12v 4 amp charger uses around 50 watts (12 x 4 = 48, plus a bit for the electronics). My 16 amp 12 v multistage battery charger uses UP TO about 200 watts, but only whilst it’s using its constant current mode.

## How much electricity does it take to charge a battery?

## Does it take more energy to charge a battery?

Generally speaking, your EV may use 12 to 15 percent more energy than what you add to your battery. That number could be lower or higher depending on charging conditions. There are a number of reasons for this.

## How does a charger know when a battery is full?

There are two criteria for determining when a battery is fully charged: (1) the final current level and (2) the peak charging voltage while this current flows. Typical sealed lead acid battery charge characteristics for cycle service where charging is non-continuous and peak voltage can be higher.

## Are car battery chargers worth it?
