Tip: Use Level 1 for overnight charging, Level 2 for daily use, and DC Fast Charging for long trips.
Power Output (kW), Voltage, and Amperage
You can think of voltage as water pressure and amperage as the flow of water. Power output, measured in kilowatts (kW), is the product of voltage and amperage. Higher voltage or amperage means more power and faster charging, but only if your car can handle it.
| Specification Type | Description |
|---|---|
| Power Output (kW) | Total power delivered during charging. Higher kW means faster charging. |
| Voltage (V) | Like water pressure. Higher voltage can speed up charging. |
| Amperage (A) | Like water flow. More amperage delivers more power. |
Charging time drops as power output rises. For example, if your car has a 60 kWh battery and you use a 10 kW charger, you can estimate charging time as 60 kWh ÷ 10 kW = 6 hours.
Onboard Charger Limits and Efficiency
Your car’s onboard charger sets the maximum speed for AC charging. Most onboard chargers range from 3.3 kW to 22 kW. Even if you plug into a powerful station, your car may only accept what its onboard charger allows. For example, a 19.2 kW charger will not charge your car faster if your onboard charger only supports 7.4 kW. Manufacturers now offer higher-capacity onboard chargers, which can reduce charging times at home.
- Onboard chargers control the voltage and current your battery can accept.
- High-power charging creates heat, so cooling systems help keep charging efficient.
