Topic: Charge time has increased by nearly 50 percent
I have been using a JuiceBox to charge my Prius Prime for 5 years. Until about a week ago, a full charge took about 2 hours. Today, it is taking 2 hours and 50 minutes. As a troubleshooter, I'm wondering how to determine whether it's a problem with the car, a problem with my JuiceBox, or a problem with my 240-volt, 30 amp circuit. The only other thing that runs on that circuit is my clothes dryer (I never charge while it is running), and it is running normally.
The increased charge time is creating an expensive problem for me when I take two trips in a row because I either have to wait a much longer time to recharge (usually not possible) or else run partially charged and thus using gasoline.
