Two electric vehicles can share one home charger, but a single charger can only charge one car at a time. Sharing works well when the two cars have different driving patterns, when you can schedule sessions around each other, or when you accept that one car may wait a few hours. Planning ahead makes the difference between a smooth routine and a daily argument over the plug.
Understanding the limit
A charger delivers power to one connected vehicle at a time. If a second car is plugged in while the first is charging, the second car will not charge until the first session ends. Moving a plug-in cable between cars is possible only if it reaches both parking spaces, and it means someone has to unplug one car and plug in the other every time.
Stagger the charging schedule
The simplest approach is to divide the overnight window. Suppose you have an eight-hour off-peak window and each car needs about 13 kWh per day. At 9.6 kW, each car needs about 1.5 hours before losses. Both cars can charge one after the other within the same night. Set the first car to start at 11 p.m. and the second to start after the first has finished, using each car's scheduling feature, so that both are ready by morning.
Plan around different needs
- Give priority to the car with the longer drive the next day.
- Treat the lower-mileage car as the flexible one that can charge on a different night.
- Keep both cars plugged in when they are parked at home, so each is ready when needed.
- Agree on a simple rule with everyone in the household about who gets the charger first.
Check the circuit before you share
Sharing a charger does not increase the power it can deliver. The charger and its circuit must be rated for the load, and the outlet or hardwired connection must match the charger's specification. Adding a second charger on the same circuit may exceed that circuit's rating, so ask a licensed electrician about adding a circuit or using a load management device. Local permits and inspections may apply, so check with your local building department before any installation.
How this applies to EVIQO chargers
EVIQO chargers are 240V units with a 25 ft cable. The 40A (9.6 kW) and 48A (11.5 kW) options add about 38 and about 46 miles of range per hour, so two daily top-ups can often fit into one night when they are scheduled one after the other. Before you choose between a plug-in and a hardwired installation, consider where each parking space sits relative to the charger and how far the 25 ft cable will reach. Every EVIQO charger comes with a 3-year warranty.
