Charging at Home

Charging Electric Vehicles Where You Live


Charging electric vehicles is easy and convenient.   There are three primary means of charging electric vehicles ranging from the common household outlet to high power fast charging stations.  The choice of charging method depends on daily driving needs and the capacity of the electrical system at the residence.

Installation of Charging Connections.   Any licensed electrician can install outlets or charging stations.  Check with your city or county to find out about requirements for building permits.   Two electrical contractors who have worked with GGEVA are:

Standard Household Outlet.   Nearly all electric vehicles - cars, motorcycles, and bicycles can be charged by plugging in to a standard 120 volt household outlet (NEMA 5-15).  The amount of time required for a full charge varies by the capacity of the vehicle’s battery.   Most electric cars will store enough energy to travel about 4 to 5 miles for each hour that the car is plugged in.  If you drive less than 40 miles per day this may be all you need.

240 Volt Charging Connections.  Electric cars can be charged more quickly with a 240 volt connection from a charging station or using an outlet similar to the circuit for a clothes dryer or an oven.    The 240 volt charging stations are usually referred to as EVSE (electric vehicle supply equipment).  Depending on the car and the capacity fo the connection, EVs can store enough energy to travel up to 62 miles for each hour that the car is plugged in to a 240 volt connection.  Most EV drivers with garages or dedicated parking spaces will install a J1772 charging station (EVSE) or Tesla High Power Wall Connector, but several types of 240 volt connections can also be used and adapters for these connections are available for most cars.  Charging stations can be permanently wired or some can be plugged in to special outlets.

Condominiums & Apartments.   California law prohibits condominium associations from prohibiting members from installing electric vehicle charging statements and establishes some requirements for the condo owners who wish to install EV charging stations.   Section 4745 of the Davis-Stirling Act specifies the EV charging station provisions for condominiums.  http://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=4745.&lawCode=CIV

Installing Wireless Charging.  Wireless charging can be installed for some EVs.  The driver simply parks the specially equipped EV over a small charging pad in the parking space and the car is charged without the use of a cable.  Go to  https://www.pluglesspower.com for more information about purchase and installation.

Residential Charging Stations.  Residential charging stations are available online, from car dealers, and home improvement stores. Some sources are:

Electricity Rates.  PG&E, MCE Clean Energy, and CleanPowerSF offer special rates for electric vehicle drivers.  These rates can apply to all of the household electricity use as well.  Switching to these rates can result in savings for EV drivers.
