Charging Multiple EVs at Home: What You Need to Know
With many households now having two or more EVs, here's how to handle charging multiple vehicles at home.
The Challenge
As EV adoption grows, many households now have two or more electric vehicles. This creates challenges around electrical capacity and charging logistics.
Option 1: Two Separate Chargers
Installing two independent chargers requires:
- Sufficient electrical capacity (usually limits both to lower power)
- Two circuits from consumer unit
- Potentially a main fuse upgrade
- Load management for simultaneous charging
Cost: £1,500-3,000 total
Option 2: Load Balancing
Many modern chargers support dynamic load balancing, automatically sharing available power between multiple chargers. When one car is charging, it gets full power; when both charge, they share.
Brands with good load balancing:
- Easee (Easee Link)
- Wallbox (Power Sharing)
- Zaptec (Pro system)
- myenergi (with hub)
Option 3: Scheduled Charging
If your cars don't need to charge simultaneously, you can:
- Schedule different charging times via apps
- Charge one car overnight, one during day (if working from home)
- Use a single charger for both (moving cable between cars)
What About Three-Phase?
If you have three-phase supply, you have more capacity to play with. A 22kW three-phase charger could theoretically charge two cars at 11kW each, or you could install multiple 7kW chargers without power constraints.
Our Recommendation
For most households with two EVs, installing two chargers with load balancing from the same manufacturer offers the best balance of convenience and cost.
