Can I share one EV charger between two parking spots?

Yes, you can share one EV charger between two parking spots, but it requires careful planning for the installation and daily use coordination. This setup is becoming increasingly popular for households with multiple EVs or properties with adjacent parking spaces.

Physical Installation Options

The most common approach is installing the charger on a post or wall-mounted bracket positioned between the two parking spots. The charging cable needs to reach both vehicles comfortably - most Level 2 chargers come with 18-25 foot cables, which typically works well for adjacent spots. You'll want to ensure the charger location allows easy access without the cable stretching across walkways or creating trip hazards.

Some homeowners opt for a pedestal-mounted charger centrally located between spots, while others choose a wall-mounted unit if there's a garage wall or fence that serves both spaces. The key is positioning it so both vehicles can connect without moving the charger itself.

Electrical Requirements in Ottawa

Under the Ontario Electrical Safety Code, you'll need a dedicated 40-amp circuit for most Level 2 chargers (which output 32 amps). This single circuit can power one charger that serves both spots - you don't need separate electrical feeds. However, an ESA permit is required for the installation, and the work must be completed by a licensed electrician.

Your electrical panel needs adequate capacity for the 40-amp circuit. If you're already near your panel's limit, you might need a panel upgrade before installing the EV charger. Most modern 200-amp panels can handle this addition, but older 100-amp services often require upgrading.

Usage Coordination

The main consideration is that only one vehicle can charge at a time. This works well for many households where charging happens overnight and vehicles have different schedules. You might charge one car from 6 PM to midnight, then switch to the second vehicle overnight. Most EVs don't need charging every single night, so alternating typically works fine.

Some families establish charging schedules or use smart chargers with scheduling features to automate the process. The key is ensuring both vehicles get adequate charging time based on your driving patterns.

Cost Considerations

Sharing one charger between two spots costs significantly less than installing two separate units. In Ottawa, expect to pay $1,200-$1,800 for a single Level 2 charger installation if your panel has adequate capacity. Installing two separate chargers would cost $2,000-$3,000 plus potentially requiring a larger electrical service.
