The vast majority of owners of electric cars (EVs), which may be either fully electric or plug-in hybrids, charge their vehicles at home overnight using AC Level 1 or AC Level 2 chargers. While garages are a common location for charging electric cars at home, installing and using the equipment outside is also OK. Equipment intended for use in the outdoors must be rated for use in the outdoors. Charging in a multifamily dwelling may be more similar to public charging due to the extra factors involved.
Establishing a Domestic Charging Infrastructure
As long as a power outlet on a dedicated branch circuit is available close to their parking site, many EV owners may satisfy their daily driving range needs by charging overnight using Level 1 equipment, at no extra expense and with no installation required. For drivers with irregular schedules, lengthier journeys, or electric vehicles with huge batteries that need more than a single night’s stay (or the normal dwell period) to completely charge, level 2 charging infrastructure is an option. It’s possible to get financial aid for charging infrastructure from the state and the power company.
Status indicators and fail-safes are usually included in Level 2 goods. Level 2 goods are more complex and “smart,” with features including data collecting, user interface systems, improved displays, charging timers, communication capabilities, and keypads. We advise hiring a licenced electrician and only using goods that have been evaluated for safety, such as those with the ENERGY STAR designation.
If a home’s electrical system is suitable for charging a car, an electrician may let the owner know. Electricity availability in certain households may be inadequate for Level 2 devices. However, if you don’t have enough circuits for Level 2 charging, a licenced electrician can easily install them.
San Jose, California, was one of the first places to establish regulations for the installation of car charging systems in detached and attached dwellings; here, the permission procedure and strategic placement of a home charging unit are laid out. Many other cities, including Seattle, have released guides for installing EV charging stations, either at homes or in businesses, in recent years.

Observing Statutory Requirements
Installations of charging equipment must adhere to all applicable regional, state, and federal laws. The local planning and zoning board may demand proper approvals.
On the page titled “Codes and Standards Resources,” you may find further information on relevant codes and standards. According to the National Electrical Code, EV charging stations must be designed to handle a continuous demand (NEC). If you want an installation that is both safe and up to code, be sure your electrician is familiar with the relevant NEC. Most of the pertinent information regarding charging equipment is found in Article 625 of the NEC. Before acquiring charging equipment or electrical services, it is recommended to follow manufacturer guidelines for information on the necessary charging equipment.
Before work can begin on a site, in many places, a detailed plan must be submitted to the relevant regulatory body for review and approval.
Charging Expenses in Terms of Electricity
Electric vehicles’ energy efficiency is often expressed in terms of kilowatt-hours (kWh) per one hundred kilometres driven. The price of energy (in dollars per kWh) and the efficiency of the vehicle (how much power is consumed to drive 100 miles) are required in order to compute the cost per mile of an EV. Using the above numbers, the cost per mile is around $0.03 if power costs 10.7 per kWh and the car uses 27 kWh to drive 100 miles.
