Electric Vehicle Charging Points

We are registered with OLEV for the installation of OLEV compliant charge points.

It used to be the case that we also had to be registered with each manufacturer so
as to install a compliant charge point. This is no longer (Oct20) the case and we can
now install any manufacturer.

We can also install any other chargepoint, whether OLEV compliant or not.

OLEV Grant

Some information about the OLEV grant.

The grant is a maximum of 350 pounds, at most 75% of installation cost.
You must already have, or have ordered an electric vehicle.
The charge point must be on the OLEV list of compliant charge points.
Simply, this means that it must be a "smart" chargepoint (uses an app).
Which pretty much eliminates all of the cheaper charge points.
And eats into the usefulness of the grant.
The grant must be applied for by the registered installer.
AFTER the event.
There's lots of paperwork, taking time and hence more cost.

Smart Chargers

To be OLEV compliant it has to be Smart chager.
Which means it has to be able to be controlled by your phone.
Some chargers have both manual and app controls.
Some ONLY have app controls.

Charging Times

Obviously varies depending upon the car, bigger means longer.
Via a 13amp socket, supplying 2kw, typically 24 hours.
Via 7kw EV chargepoint, typically 8 hours.

Electric Supply to Chargepoint

A 7kw chargepoint is supplied by a 6mm cable direct from the fusebox.
A dedicated circuit.
Hence the cost of installation is varies upon the awkwardness of
getting this cable in place.

Earth Spike

Many of the EV chargers specify the need for their own earth spike.
It must be installed at least a couple of metres away from any underground
An "interesting" requirement which can prove time consuming, if not
impossible to achieve.

or No Earth Spike

Conversely, some EV chargers include PEN Fault protection negating the
earth spike requirement. eg Zappi, WallBox Pulsar, PodPoint.
The extra cost balances against the spike installation cost.
An alternative is a special consumer unit, eg GARO.
Putting the protection at the fusebox end.
A fifty fifty cost between the two options.

Electrical Safety

The mains is AC, the car battery is DC.
There can be a tiny DC leakage back into the system during charging.
EITHER the charger has built circuitry to trap and handle it.
OR the fusebox end of the circuit has to have a special (type-f) RCBO.
Sometimes supplied with the charger, maybe not.
It pays to do the research.
Some chargers have both the RCBO and the DC handling built in, making them
"appear" to be a more expensive option. Debatable.
