Charging while at home.
Most of you will primarily be charging your electric vehicle at home. Here are a couple things you will need to know. For starters, there are two types of chargers, a standard 120-volt and a 240-volt (like your clothes dryer). The 240-volt charger will need to be professionally installed. The key difference here is really about speed. 240-volts will charge your vehicle significantly faster.
The second thing to be very aware of is charging time. Simply put, charge at night and early in the morning and you will save money on your electric bill. Midnight to 5am is the sweet spot – that’s when homes are using virtually no electricity. In San Diego you can get a special EV time-of-use rate and either opt to charge your car on the same meter as your home or to actually install a separate meter that will track your specific EV usage.
