How to use this calculator

Enter six values and the calculator returns charge time, kWh drawn, and the cost both with and without rooftop solar offset:

  1. Battery capacity (kWh) — your EV’s usable battery. 2026 Canadian volume: Tesla Model Y LR 75, Tesla Model 3 LR 75, Hyundai Ioniq 5 84, Ford Mustang Mach-E ER 91, Chevrolet Equinox EV 85, Polestar 2 LR 82, Volkswagen ID.4 82.
  2. Charger power (kW) — most Canadian homes have 100-200 A service on single-phase 240 V, supporting Level 2 chargers up to 19.2 kW (80 A). Mainstream installations: 7.7 kW (32 A) or 11.5 kW (48 A on a 60 A breaker). Brands: FLO, Ovo, JuiceBox, Wallbox, Tesla Wall Connector, ChargePoint Home Flex.
  3. Starting and target state of charge (%) — 20→80% daily for battery longevity. Tesla, Ford, GM, and Hyundai all converge on 80% as the daily ceiling.
  4. Electricity tariff per kWh — your provincial rate in CAD/kWh. Hydro Quebec D: 6.5-10.0¢. Hydro Ontario TOU mid-peak: 12.2¢, off-peak 8.7¢. Hydro Ontario ULO overnight: 2.8¢. BC Hydro Step 1: 11.0¢. EPCOR Energy (Edmonton): 11-13¢. SaskPower: 18¢. NB Power: 13.4¢.
  5. Share covered by solar PV (%) — fraction of charging energy from your panels. 30-50% is realistic for a commuter (overnight charging dominant); higher for retirees and remote workers charging midday.
  6. Charging efficiency (%) — wall-to-battery. 90% in mild conditions, drops to 75-80% in -20°C. Default 90%; adjust downward for winter modelling.

How the math works

The calculation is a direct energy balance:

energy_to_battery (kWh) = battery_kwh × (target% - start%) / 100
energy_drawn (kWh)      = energy_to_battery / efficiency
charge_time (hours)     = energy_drawn / charger_kw
grid_cost ($)           = energy_drawn × tariff
solar_savings ($)       = grid_cost × (solar_pct / 100)
final_cost ($)          = grid_cost - solar_savings

Worked example for the en-ca defaults (75 kWh, 20→80%, 11.5 kW, 13¢/kWh, 40% solar, 90% efficiency):

  • Energy to battery = 75 × 0.6 = 45 kWh
  • Energy drawn = 45 / 0.90 = 50 kWh
  • Charge time = 50 / 11.5 = 4.35 h ≈ 4 h 21 min
  • Grid cost = 50 × $0.13 = $6.50
  • Solar saving = $6.50 × 0.40 = $2.60
  • Final cost = $3.90 per session

A Canadian driver doing 20,000 km/year on a 4 km/kWh EV draws 5,000 kWh of charging. At 13¢ that’s $650/yr; on Hydro Ontario ULO overnight it drops to $140/yr; with 40% solar offset on blended rate $390/yr. Vs. a 9 L/100km petrol car at $1.65/L ($2,970/yr fuel), even modest charging arrangements save $2,300-2,800/yr.

Canadian charger types — Level 1, Level 2, and DC fast

Level 1 (120 V, 1.4 kW): Standard household outlet. Adds ~8 km/hour at +20°C, drops to negative-net in deep winter. Fine for plug-in hybrids and short-commute (under 40 km/day).

Level 2 (240 V, 7.7-19.2 kW): Canadian mainstream. 240 V split-phase from a dedicated 40 A or 60 A breaker. CSA C22.1 Section 86 governs installation; CSA C22.2 No. 280 covers EV supply equipment. Common 2026 hardware-only retail (CAD): FLO Home X8 $899, Ovo Smart Home $799, JuiceBox 40 $799, Wallbox Pulsar Plus 48A $899, Tesla Wall Connector $550, ChargePoint Home Flex $899.

DC Fast (50-350 kW): Public networks: Electrify Canada, FLO, Petro-Canada, Tesla Supercharger, ChargePoint, Ivy. 2026 typical rates: 35-65¢/kWh. A 20→80% charge on 75 kWh costs $17-30 vs. $1.40-6.50 at home.

Solar PV in Canadian conditions

Canadian PV potential is better than most realise: Ottawa rivals Berlin, Calgary outperforms Hamburg, and southern BC matches Madrid. NRCan’s PV potential atlas shows annual yields of 1,200-1,400 kWh/kWp in Ontario, Quebec south, BC south coast, and southern Prairies — comfortably enough to cover EV consumption with a typical 8 kW residential array.

Net metering rules vary: Ontario annual true-up at retail rate (highest value), Alberta retailer-credit (variable, often 80% of energy charge), BC variable export, Quebec annual true-up. The Canada Greener Homes Loan provides 0% interest up to $40,000 over 10 years for solar + EV charging installations.

What changes the math

Lowers the cost (good)

  • TOU/ULO plans in Ontario — overnight EV charging at 2.8-8.7¢/kWh
  • Solar PV with smart wallbox running solar-divert mode for daytime self-consumption
  • Greener Homes Loan — 0% interest financing for solar + EV charger up to $40,000
  • Provincial rebates (Ontario EV ChargeON, BC SCRAP-IT/EV, Quebec Roulez Vert) — variable but ongoing
  • Hydro Quebec D rate — among the cheapest residential electricity in North America

Raises the cost (bad)

  • DC fast charging as a daily habit — 4-7× home cost
  • Cold-weather efficiency loss — 15-25% more energy needed below -10°C; pre-condition the battery while plugged in
  • Off-grid or non-net-metered solar — full self-consumption only, no export credit

Pair this with the output calculator, savings calculator, and cost calculator

Output gives provincial annual yield from NRCan models, savings translates into bill offset, cost shows installed price for a typical 8-12 kW Canadian residential system.

Frequently asked questions

How long does a Level 2 charger take to charge an EV in Canada?
On an 11.5 kW (48 A / 240 V) Level 2 home charger — the most common Canadian residential setup — going from 20% to 80% on a 75 kWh battery (Tesla Model Y, Hyundai Ioniq 5, Ford Mustang Mach-E) takes about 4 hours 20 minutes accounting for ~10% AC losses. A 7.7 kW (32 A) unit stretches the same charge to 6.5 hours. Cold weather matters in Canada — winter battery preconditioning and cabin heat add 15-25% to charging energy in -20°C conditions, which the calculator can be adjusted for via the efficiency input.
How much does it cost to charge an EV at home in Canada?
Canadian residential electricity is among the cheapest in the OECD. Hydro Quebec residential D rate: 6.5¢/kWh first 40 kWh/day, 10.0¢ above. Hydro Ontario time-of-use off-peak: 8.7¢/kWh, on-peak 18.2¢. BC Hydro Step 1: 11.0¢/kWh. Manitoba Hydro: 10.5¢/kWh. At an average ~13¢ blended rate, a 20-80% charge on 75 kWh costs about $6.50 from grid. Ontario ULO (Ultra-Low Overnight) plan drops 23:00-07:00 to 2.8¢/kWh — same charge for $1.40.
Are home solar panels worth it for charging an EV in Canada?
Yes for Ontario, Alberta, Saskatchewan, and BC where retail rates and solar irradiance combine favourably. A typical 8 kW Canadian rooftop array generates 9,500-11,000 kWh/yr in southern Ontario or BC (NRCan PV potential atlas), enough for 35,000+ EV km annually. Net metering exists in every province (rules vary): Ontario allows annual true-up at retail rate, Alberta credits at retailer's energy charge, BC at variable export rate. The Greener Homes Loan offers 0% interest up to $40,000 for solar + EV charger installs, repayable over 10 years.
Do I need a Level 2 home charger or is Level 1 enough for Canadian winters?
Level 1 (120 V, 1.4 kW) is borderline in Canadian winters — battery thermal management and cabin preconditioning can consume 1-2 kWh/hour overnight in -20°C, leaving Level 1 unable to net-positive charge. Level 2 (240 V, 7.7-11.5 kW) is essentially required for any commuter doing more than 30-40 km/day in winter. Common 2026 Canadian Level 2 hardware: FLO Home X8 ($899), Ovo Smart Home ($799), JuiceBox 40 ($799), Wallbox Pulsar Plus ($899), Tesla Wall Connector ($550).
What standards apply to home EV charger installation in Canada?
Installations must follow CSA C22.1 Canadian Electrical Code Part I, Section 86 (Electric Vehicle Energy Management Systems) and Section 26 (general installation). All work must be performed by a licensed electrician and inspected by the provincial electrical safety authority (ESA in Ontario, BC Safety Authority in BC, Hydro-Québec in QC). The charger needs Class A GFCI per CSA C22.2 No. 280. Federal Greener Homes Grant (closed to new applicants in 2024) and the ongoing Canada Greener Homes Loan still cover up to $5,000 of EV charger installation.
