A Guide to Home EV Charging

Looking to charge your electric vehicle (EV) at home? Want to maximize value and minimize expense on home EV Charging? Home EV charger or wall connector is a convenient and cost-effective way to ensure a fully charged battery every morning when you wake up.

This comprehensive guide will walk you through the essential steps, cost, and key considerations to set up an efficient home charging station for your EV.

Home EV Charging Benefits

Imagine never have to stop by a gas station during rush hour again, instead, having unlimited power supply available at home, wherever and whenever you park, make better use of your time. For many EV drivers, this is coming true.

Fully charge an electric car takes more time than refilling gasoline. However, the gap is shrinking with the time. Remember, the EV world is versatile – and evolving fast.

Saving Money on Home Charging

Driving an EV was already 65% cheaper per mile. Take advantage of lower residential electricity rates by home charging, especially during off-peak hours compared to public charging stations.

Sustainability

Install once, charge whenever. Home EV charging makes “refill” more predictable and sustainable. EV owners can recharge on their own schedule, ensure your EV is always ready for the next trip.

Charge Smarter

Smart control and preset your charging plan to extend battery life. Pick charging speed, schedule charging, and get reminders to plug in.

DC Fast charging

Better for EV Battery

Research shows frequent DC (240V) fast charging can degrade battery capacity faster than AC (120V) charging. Using level 2 home charging station to protect your battery and meets day-to-day needs.

No More Range Anxiety

No fear of running out of power before reaching the next charging point. No more time spent on route planning and foresight. Rely on the flexibility of home charging.

Options to Charge EV at Home

Level 1 EV Charger

Level 1 EV charging, also known as a portable EV charger, is the simplest and most accessible charging option. It typically comes with your electric vehicle and plugs into a standard household outlet (120 volts).

While level 1 chargers are slower than other options, they are ideal for overnight charging at home, especially for shorter daily commutes.

Level 2 EV Charger

Level 2 EV chargers (Dryer Plug) offer faster charging speeds than level 1, making them perfect for longer commutes, frequent driving, or quick recharges during the day. Used in homes, workplaces, and public charging networks, they provide flexibility and can fully charge an EV battery in 4-8 hours.

Choose a home EV charger for on-the-go ease or invest in a level 2 charger for home charging convenience.

How to charge EV at home?

Electric vehicles (EVs) become increasingly popular, most EV drivers charge their car at home a majority of the time. After all, it is the most cost-effective and efficient way to charge an electric car, plug in when you get home from work and wake up to a fully charged car in the morning. This means no more gas station visits.

And yes, there are portable EV chargers available. These Level 1/Level 2 EV chargers are compact and allow you to charge your EV from a standard electrical outlet.

Do I need to install home charging station?

Most EVs can charge via a standard 120-volt outlet, so you may be able to use an existing outlet. However, the charge speed is relatively slow, a rate of 3-6 miles per hour.

If you’re looking for a faster charging method, installing a 240-volt Level 2 charging station can provide charging speeds of 20-30 miles per hour which is 4-8 times faster.

In most cases, you will not need permit to install a home EV charging station into an existing 240V outlet, such as NEMA 14-50P (a common outlet for electric stoves) or a NEMA 6-50P (a common outlet for welder plugs), which makes it easy to match! If not, you’ll need a professional electrician to add wiring to your home or upgrade the electrical panel.

How can I charge my EV car at home?

You can charge your electric car at home using either standard 120-volt (V) home outlets (Level 1) or 208-240V outlets (Level 2) similar to those used for dryers.

The charging time and speed depend on the kilowatt-hour (kWh) rating of EV charger and the size of the battery. Below example valid for any EV models:

EV battery capacity – 42kWh
EV charger energy delivery – 7.2kW
Total hours to charge = 42kWh / 7.2kW = 5.83 hours

How long does it take to charge EV at home?

EVSE Level 1 chargers will take 40+ hours to charge a BEV to 80% from empty and 5-8 hours for a PHEV.

The extended charging time is why EV charger Level 2 have become the preferred choice for most EV owners. Level 2 EV chargers offer a faster charging speed in 4-8hours to 80%, more practical and convenient to charging an EV overnight at home.

Buying Portable EV Charger

Charging at Home Considerations

It’s necessary to buy a portable EV charger in addition to other charging options on the road, as you don’t need to frantically search for a charger when battery is running low. There are two EV levels of portable charger: Level 1 and Level 2.

A Level 1 EV charger plugs into a standard NEMA 5-15 wall outlet and provides up to 120V and 16A of power. Meanwhile, a Level 2 portable EV charger plugs into a high-powered outlet (usually a NEMA 14-50) and provides up to 240V and 48A of power.

Understand Your Charging Needs

  • Determine your daily mileage and charging habits. If you primarily charge at home or have easy access to charging stations on regular routes.
  • Identify your EV’s battery capacity and home’s power level to gauge how long it will take for a full charge.

  • How fast you need the charging speed to be and your price range – Factor in the upfront cost, maintenance, and potential installation requirements.

Choose the Right Home Charger

  • Ensure your electrical panel’s capacity to handle the additional load of a portable EV charger or charging station. Engage a qualified electrician to install the home charging station and ensure compliance with local electrical codes.
  • EV chargers need to be UL or TUV certified. It’s important to ensure they are safe for home charging and have passed all the mandatory guidelines.
  • Research and select a Level 1 or Level 2 charging station suitable for your EV model. Consider features like scheduling, energy monitoring, and integration with smart home systems to optimize your charging efficiency.

Cost Considerations

  • Understand the installation costs, which may include equipment, labor, permits, and potential electrical upgrades.
  • Estimate the cost of electricity based on your utility rates and the energy consumption of your EV.
  • Consider potential savings compared to traditional gasoline costs and explore time-of-use (TOU) electricity plans for reduced rates during off-peak hours.

Government Incentives and Rebates

  • Research local, state, and federal incentives, grants, and tax credits available for EV charging station installations.
  • Take advantage of financial support programs that can help offset installation costs.
