Choosing an 11 kW Type 2 EV charger: what to consider for home charging

An 11 kW Type 2 EV charger can be a practical solution if you want to charge your electric car or plug-in hybrid faster at home than you can from a standard socket. However, there’s a bigger difference between a suitable three-phase EV charger and an unsuitable purchase than the wattage on the packaging might suggest.

Look out for these three common pitfalls:

  • 11 kW without a suitable connection: an 11 kW charger typically uses a 400 V three-phase connection and a maximum of 16 A per phase. A standard 230 V circuit isn’t suitable.
  • Mistaking a Type 2 plug for a complete charging solution: Type 2 describes the vehicle connector. It doesn’t automatically tell you about charging power, safety features, controls or installation.
  • Smart features that depend on the internet: app control can be handy, but check whether RFID or a local start function will still work if your Wi-Fi goes down.

Key specifications of an 11 kW electric car charger

1. Check the voltage, phases and vehicle compatibility

A 400 V EV charger uses three phases. For the TDC ENERGY RAC11, the product specifications state 400 V, three-phase, maximum 16 A at 11 kW. The supplied five-pin 16 A CEE plug is only suitable for a compatible electrical installation.

Check in advance:

  1. Whether your home or business premises has a suitable three-phase connection.
  2. Whether the circuit, wiring and safety features can handle the charging power.
  3. Whether your car’s onboard charger can actually accept 11 kW AC.

Not every EV or plug-in hybrid charges at 11 kW. Some models, for example, limit AC charging power to 3.7 or 7.4 kW. According to the product information, the actual charging speed depends on the vehicle’s onboard charger and the electrical installation.

2. Look beyond the Type 2 label

A Type 2 charging station uses the IEC 62196-2 connector standard, which is common among European electric cars and plug-in hybrids. This makes the charger suitable for vehicles with a Type 2 charging socket, but always check your car’s manual.

A 5-metre cable gives you more flexibility if the charging station can’t be installed right next to the charging port. Also check how the cable is stored. A holder and protective cap help protect the connector from dirt and moisture.

3. Safety features and outdoor use

An AC home charging station should do more than simply supply power. According to the TDC ENERGY RAC11 product specifications, its safety features include:

  • overvoltage and undervoltage protection;
  • overload and overheat protection;
  • earth continuity monitoring;
  • Type A RCBO, 30 mA AC plus 6 mA DC leakage detection;
  • emergency stop protection.

According to the product specifications, the connector is rated IP54 when in the holder and IP65 with the protective cap fitted. This doesn’t mean the entire charging station is waterproof in all conditions. If you’re mounting it outdoors, it’s a good idea to install it in a sheltered spot, fit it correctly and protect it from direct rain. Don’t use a pressure washer or immerse the unit in water.

App, RFID and everyday use

An RFID EV charger can be useful when several people use the same charging station. The TDC ENERGY RAC11 comes with two RFID cards. According to the product information, RFID control can also work without a network connection. App features use Wi-Fi or Bluetooth and may require a compatible network connection.

A display makes it easier to monitor the charging process. This model’s 3-inch segment LCD shows the charging status and key operating information. That’s useful if you don’t want to keep opening the app.

Be wary of features that aren’t listed in the product specifications, such as dynamic load balancing, automatic electricity cost calculations or solar panel integration. If you need these features, check explicitly that they’re supported. Don’t rely on the word “smart” alone.

Installation and maintenance

Have a qualified electrician install and commission a fixed 11 kW Type 2 EV charger. They can assess whether your consumer unit, residual current protection, earthing and cable cross-section are suitable. Also check whether using household appliances at the same time could cause an overload.

To help your charger last longer:

  • inspect the cable, plug and connector regularly;
  • use the protective cap when the connector isn’t in the holder;
  • don’t pull the cable tight, and only coil it up once charging has stopped;
  • don’t use the charging station if any parts are damaged or unusually hot;
  • don’t open or repair the unit yourself.

Frequently asked questions about an 11 kW Type 2 EV charger

Do I always need a three-phase connection for 11 kW?

A suitable 400 V three-phase connection is needed for 11 kW at 16 A. Ask an electrician to check whether your existing installation supports this and whether sufficient capacity is available.

How long does an 11 kW EV charger last?

Its lifespan depends on installation, use, weather conditions and maintenance. Protect the connector, avoid physical damage and, if possible, install an outdoor charger in a sheltered spot. The TDC ENERGY RAC11 comes with a two-year warranty; your statutory warranty rights may also apply.

How much does it cost to charge at home at 11 kW?

The cost depends on your electricity tariff, your car’s energy consumption and any installation costs. An 11 kW charging rate reduces charging time, but it doesn’t make electricity cheaper per kilowatt-hour. So check your energy tariff and your car’s actual AC charging power too.
