Those switching from gasoline to electric vehicles can find savings, especially with home charging.

Fundamentals of Electric Car Charging

Electric car charging involves more than just plugging in a vehicle. Key elements include understanding kilowatts and kilowatt-hours, the basics of EV batteries, the types of EV chargers, and the overall charging process.

Understanding Kilowatts and Kilowatt-Hours

Kilowatts (kW) measure power, indicating how much energy an electric vehicle (EV) uses or how fast it can charge. Kilowatt-hours (kWh) measure energy use over time, showing the total electricity consumed.

For example, if an EV charges at a rate of 7 kW for one hour, it consumes 7 kWh of energy. Understanding these units helps calculate charging costs. If electricity costs $0.17 per kWh, charging with 40 kWh would cost $6.80.

Electric Vehicle Battery Basics

Electric vehicle batteries store energy to power the car. The capacity of an EV battery is measured in kWh, which determines how far the car can travel. Battery size varies by model, with typical capacities ranging from 40 kWh to 100 kWh.

Usable energy is important, as not all stored energy can be used due to safety buffers. For instance, a battery with a 100 kWh capacity might have 95 kWh of usable energy. Battery health affects range and charging speed over time.

Types of EV Chargers

EV chargers come in three levels. Level 1 chargers use a standard 120-volt outlet, providing about 2-5 miles of range per hour. Level 2 chargers, using a 240-volt outlet, are common for home charging and public stations, offering 10-60 miles of range per hour.

DC Fast Chargers (Level 3) are the fastest, using high power to deliver up to 350 kW. These can charge an EV to 80% in 20-30 minutes. Each type suits different needs, from overnight home charging to quick top-ups on long trips.

The Charging Process

Charging an electric vehicle involves connecting it to an EV charging station using a charging cable. The car’s charging system manages the flow of electricity to the battery. Charging times depend on the battery size, charger type, and current battery level.

At home, a Level 2 charger can fully charge a typical EV in 8-12 hours. Public charging stations vary, with DC Fast Chargers providing rapid charges but potentially costing more. Battery health is best maintained by regular, moderate charges rather than frequent rapid charging.
