One of the first questions people ask when considering an 11kW EV charger station is: How fast will my vehicle charge? The charging speed can vary depending on the capacity of your electric vehicle’s battery and the state of charge when you plug in.

How Fast Can an 11kW EV Charger Charge My Car?

An 11kW EV charger can typically add about 40-60 km of range to an EV per hour of charging. For example:

• A car with a 40kWh battery can be fully charged in about 4 to 5 hours with an 11kW charger.
• A larger battery, such as a 60kWh or 100kWh battery, will take longer but can still charge significantly faster than with a lower-powered charger.

The charging time will depend not only on the power output of the charger but also on the onboard charger capacity of your EV. If your vehicle can only accept 7kW, an 11kW charger will only charge it at 7kW, meaning the charger’s maximum output will not be fully utilized.

3. Compatibility with Your EV

When choosing an 11kW EV charger station, compatibility is a critical consideration. Not all electric vehicles can support charging at 11kW speeds, so it’s important to verify whether your vehicle is compatible with this charging power.

Onboard Charger Capacity

Every EV has an onboard charger that determines the maximum charging speed it can handle. If your EV’s onboard charger supports up to 7kW or 22kW, using an 11kW charger would only charge it at the maximum rate supported by the vehicle.

Tip: Always check your vehicle’s specifications to ensure that it can take advantage of an 11kW charger.

Connector Type

The 11kW EV charger typically uses the Type 2 connector (also called the Mennekes connector) in most countries, including Europe and many parts of Asia. However, some regions, particularly North America, may use different standards (e.g., J1772 connectors). Ensure that the connector type of the charger is compatible with your car’s charging port.

Charging Standard

Make sure that the 11kW charger supports the correct charging standards for your EV. For example, some cars may only be compatible with a specific type of charger, and others may support multiple types (e.g., Type 1 and Type 2).
