Two levels, one goal: a full enough battery by morning
Every electric vehicle sold in Canada can charge from a home electrical system. The question is how fast. Home charging comes in two flavours, Level 1 and Level 2, and the difference is mostly about voltage and the circuit behind the plug.
Level 1 uses a standard 120 V household receptacle and the portable cord set that usually comes with the car. Level 2 uses 240 V, the same voltage your dryer or range uses, delivered through a dedicated circuit to a wall-mounted charger (properly called EV supply equipment, or EVSE).
Neither level is the DC fast charging you see at highway stations. That equipment needs large commercial services and is not something a house is built for.
How much range each one really adds
Level 1 is slow. As a rough guide it adds somewhere around 5 to 8 km of range per hour of charging, depending on the vehicle. Over a 10 to 12 hour night that can be enough for a short commute, but not much more.
Level 2 is several times faster. The exact rate depends on three things: the size of the circuit, the charger's setting, and the car's onboard charger, which sets a ceiling no matter how big the circuit is. Most households find a Level 2 unit refills a typical day of driving in a few hours.
In an Edmonton January the car spends some energy warming its battery before it charges at full speed. Level 1 feels this the most, because there is so little power to spare. See charging in Edmonton winters.
When Level 1 is enough
Level 1 can work well for some households. It is worth trying first if most of these are true:
- You drive a plug-in hybrid with a small battery.
- Your daily driving is short and predictable.
- The car sits plugged in for 10 hours or more most nights.
- You park in a heated or attached garage, so winter losses are smaller.
- There is a suitable receptacle near the parking spot that is not shared with a freezer, block heater or shop tools.
That last point matters. A portable cord set draws a steady load for hours. If the receptacle is on a circuit with other things, or the receptacle is worn, you can get nuisance tripping or a warm plug. Never run a charger through an extension cord.
If the plug or receptacle feels hot, looks discoloured or smells like burning plastic, unplug the car and stop using that outlet. Call a licensed electrician to check it before you charge there again.
When Level 2 makes sense
For a fully electric vehicle, Level 2 is what most owners end up with. It is the right call if you drive longer distances, share one car between two drivers, have two EVs, or park outside where winter cuts into charging speed.
It also gives you flexibility. With a few hours of charging you can top up in the evening after a long day instead of waiting overnight. Most Level 2 units also connect to an app, so you can schedule charging and see how much energy the car used.
What goes into a Level 2 installation
A Level 2 charger is a continuous load, so the circuit, wire and breaker must be sized for that duty under the Canadian Electrical Code. Section 86 of the code deals specifically with electric vehicle charging systems. The installation needs an electrical permit: in Edmonton that comes from the City, elsewhere in Alberta from your municipality or its accredited agency.
What drives the cost of the job is mostly site-specific:
- Panel capacity. Whether your existing service can carry the extra load. See can my panel handle an EV charger.
- Distance. How far the charger is from the panel, and whether the wire runs through a finished basement, an attic or underground to a detached garage.
- Space in the panel. A 2-pole breaker needs two spaces.
- Load management. If the service is tight, a load management device can avoid a service upgrade.
- Outdoor work. Exterior mounting, weatherproof fittings and protection from snow and vehicles.

Our honest recommendation
If you are not sure, start by tracking how far you actually drive in a week. Many people overestimate it. Try the Level 1 cord for a couple of weeks in the shoulder season. If you are running short, or winter arrives and the battery is not recovering overnight, it is time for Level 2.
Also think about the next ten years, not just the next car. Many Edmonton households that start with one EV add a second within a few years. If you are opening walls or trenching to a detached garage anyway, it often makes sense to run a circuit sized for the future, even if you set the charger lower today.
If you already know you want Level 2, have the electrician check your panel before you buy a charger. The right charger setting depends on what your service can spare, and some chargers have load management features built in.
Common questions
Can I plug my EV into the outdoor outlet on my house?
Only if it is in good condition, on a circuit that is not shared with heavy loads, and protected as the code requires for outdoor receptacles. Many older outdoor outlets are shared and worn. Have an electrician look at it before you rely on it every night.
Do I need a permit for a Level 2 charger?
Yes. Adding a new circuit for an EV charger requires an electrical permit. In Edmonton the City issues it; elsewhere in Alberta it comes from the municipality or an accredited agency.
Will a bigger charger always charge faster?
No. The car's onboard charger sets the limit. If your car can only accept a certain amount of power, a larger circuit will not speed it up.
Is a plug-in Level 2 charger better than a hardwired one?
A plug-in unit is easier to take with you if you move, but the receptacle must be rated for the continuous load and it is one more connection that can wear. For daily use and outdoor locations we usually recommend hardwiring.
Codes and permit rules change and every building is different. For work on your system, talk to a licensed electrician and your local permit authority.
