The majority of EV charging occurs at home overnight so cars are fully charged and ready to go in the morning. The PUD encourages customers to charge EVs during off-peak hours, beginning at 10 p.m.
Any EV can plug into a standard wall socket to charge. Charging for short trips can be done through a standard wall socket (Level 1 charging) while charging for long trips can be supported by installing a faster charger (Level 2 charging).
When considering home charging alternatives, customers should consider the distance they will be driving and their preferences about charging time. Charging time depends on the EV, how "full" the battery is and the charger type.
LEVEL 1: Home Charging
Voltage Required: 120V (standard wall socket)
1-hour Charging: 2-6 miles driving distance
LEVEL 2: Home, Workplace & Public Charging
Voltage Required: 240V
1-hour Charging: 10-25 miles driving distance
LEVEL 3: Fast Charging is only available at public charging stations and can fully charge an EV in under an hour, giving EV drivers an extra boost if needed. (CLICK FOR MAP OF PUBLIC CHARGING STATIONS)
EV drivers who live in an apartment, condo, or townhome should talk to their building manager or homeowner’s association about charging options for EVs. Some workplaces also offer charging stations as a resource for their employees, which can serve as an effective alternative to home charging.
Charging time depends on the electric vehicle, how “full” the battery is, and the charger type. In general, Level 1 will provide 2-6 miles per hour of charging, and Level 2 will provide 10-25 miles per hour of charging. Level 3 is only available at public chargers and can fully charge an EV in under an hour giving EV drivers an extra boost if needed.
Tips for installing Level 2 charging at home:
- It is recommended that you charge on a dedicated circuit (and some cars even require a dedicated circuit). Customers can work with an electrician to assess the electrical load of the vehicle they might buy and determine if an upgrade is needed at their homes.
- Customers purchasing an EV need to contact their local city planning department to obtain any required permits if an electrical upgrade is needed. The state has developed model ordinances for municipal governments to help guide this process.
- The PUD recommends EV owners follow the safe operating procedures defined in the car's owner manual.
- The PUD asks customers to fill out our New Service Questionnaire & Application Form and contact the utility if they’re considering the purchase of an electric vehicle so that the utility can plan appropriately for electrical needs in their neighborhood.
