What is a battery electric vehicle?

A battery electric vehicle (BEV) is a vehicle that uses an electric motor to convert chemical energy stored in rechargeable batteries into forward or reverse motion. Pure BEVs have no on-board internal combustion engine.


What is an electric vehicle?

An electric vehicle (EV) is sometimes used to refer to any form of electrification on a vehicle. Most commonly, an EV\ is a vehicle that runs exclusively on electricity.


What is a hybrid electric vehicle?

A hybrid electric vehicle (HEV) is fully powered by fossil fuels, a small battery is recharged using regenerative braking alongside the combustion engine. All energy created originates from fossil fuel.


What is an EVSE / 3-pin cable?

An EVSE (electric vehicle supply equipment) is a 3-pin plug cable, otherwise known as an occasional use cable or granny cable. 


What is charge curve?

The charge curve is a curve of which the power consumed goes through during vehicle charging. This begins with the vehicle communicating to the charging point and picking the best charging speed (this will alter depending on the temperature of the battery and the speed of charge the charging point can provide, among some of the many variables). Once the vehicle is taking the chosen charge rate, both the car and charging unit will try to sustain this charge rate until the battery reaches 80%. After the battery has charged to 80% the charge rate will slow in order to protect the battery.


Who are the Office for Low Emission Vehicles?

The Office for Low Emission Vehicles (OLEV) is a team working across government to support the early market for ultra-low emission vehicles (ULEV).


What is a type 1 connector?

A type 1 connector is a five pin plug that also features a clip, this connector is common in the US and is typically found on EVs manufactured by Asian and US brands (e.g. Nissan, Mitsubishi and GM/Vauxhall/Opel). However its prominence is fading as we see a move to Type 2.


What is a type 2 connector?

A seven pin plug with one flat edge, this connector was originally favoured by European brands e.g. BMW, VW group, but is now becoming the most popular on all cars. It can carry three-phase power and locks into the socket of a charging point.


What is a CHAdeMO connector?

A CHAdeMO connector is a round four pin plug, this connector is only used for rapid charging points and is typically compatible with EVs manufactured by Asian brands e.g. Mitsubishi and Nissan.


What is a CCS connector?

The CCS connector has been standardised by the EU, this plug combines two DC pins arranged below the Type 2 AC connector and uses 3 of the Type 2s pins. Found on most Type 2 BEVs.


What is a kW?

A kilowatt is simply 1,000 watts, which is a measure of power. Charging points are usually measured in kW as this is the power they are capable of providing.


What is a kWh?

A unit of energy equivalent to the energy transferred in one hour by one thousand watts of power. Electric car batteries are typically measured in kilowatt hours. 1 kilowatt hour is typically 3-4 miles of range in a BEV.


What is AC?

Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. Current flowing in power lines and normal household electricity that comes from a wall outlet is alternating current.


What is DC?

Direct current (DC) is electrical current which flows consistently in one direction. The current that flows in a flashlight or another appliance running on batteries is direct current.


What is an ultra low emission vehicle?

An Ultra low emission vehicles (ULEV) is currently defined as having less than 75 grams of CO2 per kilometre (g/km) from the tailpipe.


What is a fuel cell electric vehicle?

A fuel cell electric vehicle (FCEV) is a vehicle that uses hydrogen Fuel Cells to power the electric motor. Electricity is created by the fuel cells.


What is an internal combustion engine?

An internal combustion engine is a vehicle that uses an internal combustion engine and fossil fuels such as a standard petrol or diesel vehicle.


What is ICE’d?

When a charge point is occupied by a vehicle with an internal combustion engine (ICE) , preventing an EV from charging.


What is an RFID card?

Using the same technology used in public transport travel cards, these cards are used by many charge points to allow access to EV charging.


What is ‘range anxiety’?

The term given to a fear of running out of charge while driving a plug-in electric vehicle. This fear can be avoided by top-up charging wherever you park throughout the day and en-route charging on longer journeys.


What is smart charging?

A term used  for a series of functions that a Wi-Fi connected chargepoint can perform. Typically this refers to things like load balancing, energy monitoring and “managed charging”, i.e. shifting charging periods away from periods of high grid demand and/or low grid supply and to periods of low grid demand and/or high grid supply.


What is vehicle to grid?

Vehicle to grid, otherwise know as V2G is the concept of using your electric car battery to release power back through the charger either for use in the local building or back into the grid at times of high grid demand.


What is three phase power?

Often found on commercial and industrial sites, this provides three alternating currents and allows for 22kW AC charging. Significant three-phase power availability is also a prerequisite for DC rapid charger installation.


What is single phase power?

Typically found in most UK homes and some businesses, this is what all standard 3 pin plug sockets provide. A single-phase electricity supply can power a dedicated charge point up to 7kW.


What is trickle charging?

The slowest type of charging, this is best reserved for long overnight charges at home and is either provided safely by de-rated dedicated charge points, or through a standard 3 pin plug, which lacks certain safety features.


What is slow charging?

Slow charging is a better option for home charging, this allows for both top up and overnight charging through a dedicated charge point.


What is fast-charging?

Ideal for top up charging, most fast charge points offer 7kW, ideal for keeping you going while out and about. Typically found in homes, workplaces and in public car parks where people typically spend circa 40 mins or more.


What is rapid charging?

Rapid charging is typically used for en-route charging on long distance journeys, rapid chargers can also be used as occasional “caught short” chargers, particularly if available somewhere convenient, e.g. a supermarket, motorway service station. Rapid chargers typically provide 50kW.


What is the New European Driving cycle?

The New European Driving Cycle (NEDC) was designed to assess the emission levels of car engines and fuel economy in passenger cars. A less favourable test when it comes to electric vehicles, the NEDC gives quite a generous assessment of range.


What is the Worldwide Harmonised Light Vehicle Test Procedure?

The Worldwide harmonised Light Vehicle Test Procedure (WLTP) is a more thorough emissions and efficiency testing regime that has broadly superseded the NEDC. The test provides a less optimistic verdict on real world electric range, but it is arguably still more optimistic than a vehicle’s actual real world range.


What is an extended range electric vehicle?

In the same way that a plug-in hybrid is an extension of a hybrid, an extended-range electric vehicle (EREV) is an extension of a plug-in hybrid. A conventional engine is retained but is much smaller and the battery capacity is generally increased. In a pure EREV, the wheels can only be driven by the electric motor(s), the internal combustion engine only being used to hold or recharge the batteries as they become depleted.


What is a tethered unit?

A tethered unit is a charge point with a cable attached. 


What is a socketed unit?

A socketed unit is a charge point without a cable attached.
