When connected to WiFi, you can track energy usage and view your charging history. If you have more than one EV, you can set up your two (or more) JuiceBox Pro units to share one electrical circuit. For example, say you have only 40A capacity in your panel but have two vehicles charging simultaneously. You can program your JuiceBox Pro units to never exceed 40A combined draw. If only one car is charging, it gets the full 40A of current. When the second car plugs in, the current gets shared 20A / 20A between the two vehicles. When one of the cars finishes charging, the remaining car ramps back up to 40A.
Additionally, WiFi enabled chargers may be eligible for demand response and other energy programs that pay users financial incentives to modulate their chargers in certain utility territories.
