MORE INFORMATION ABOUT HENLEY’S CHARGING POINTS

 

Having been asked to provide more information on this installation [Chargemaster] Vicky Mumford, Transport & Highways, WCC, has kindly provided the following information, more nationally based data can be found on Zap-Map site –

Henley Chargemaster Installation –  Consist of 7KWh chargers which will provide approximately 60 miles from a 2 hour charge. Give the location of the charge points in Henley and the parking restrictions during the day, it enables users to obtain a ‘top up’ charge when visiting Henley.

In General:

Fast chargers are typically rated at either 7 kW or 22 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 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 be parked at for an hour or more.

The majority of fast chargers are 7 kW and untethered, though some home and workplace based units have cables attached.

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 in to 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 on-board charger will only draw a maximum of 3.3 kW, even if the fast charge point is 7 kW or 22 kW.

Tesla’s ‘destination’ chargers provide 11 kW or 22 kW of power but, like the Supercharger network, are intended only or use by Tesla models. Tesla does provide some standard Type 2 chargers at many of its destination locations, and these are compatible with any plug-in model using the compatible connector.

Type 2 –
7-22 kW AC

Type 1 –
7 kW AC

Commando –
7-22 kW AC

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.

The JPC would remind drivers that the same restrictions apply to parking at these and all other road parking spaces in Henley, and the 2 hour stay must be observed in order to avoid penalties.
