Units are either untethered or have tethered cables
Fast chargers are typically rated at either 7.4 kW or 22/11 kW (single- or three-phase 32A). The vast majority of fast chargers provide AC charging, though some networks are installing 25 kW DC chargers with CCS or CHAdeMO connectors.
Charging times vary on unit speed and the vehicle, but a 7.4 kW charger will recharge a compatible EV with a 40 kWh battery in 4-6 hours, and a 22 kW charger in 1-2 hours. Fast chargers tend to be found at destinations such as car parks, supermarkets, or leisure centres, where you are likely to be parked at for an hour or more.
Should a cable be tethered to the device, only models compatible with that connector type will be able to use it; e.g. a Type 1 tethered cable could be used by a first-generation Nissan Leaf, but not a second-generation Leaf, which has a Type 2 inlet. Untethered units are therefore more flexible and can be used by any EV with the correct cable.
Charging rates when using a fast charger will depend on the car’s on-board charger, with not all models able to accept 7 kW or more.
These models can still be plugged into the charge point, but will only draw the maximum power accepted by the on-board charger. For example, a Nissan Leaf with a 3.3 kW onboard charger will only draw a maximum of 3.3 kW, even if the fast charge point is 7.4 kW or 22 kW.
Almost all EVs and PHEVs are able to charge on a Type 2 units, with the correct cable at least. It is by far the most common public charge point standard around, and most plug-in car owners will have a cable with a Type 2 connector charger-side.
