800V is one of the most powerful types of charging that can add as much as 60 miles of power in just 5 minutes.


This references both Alternating and Direct Currents. See our definitions of AC and DC for specific definitions of these types of electricity flows.


An Alternating Current is a type of electricity flow that can charge electric vehicles at slower speeds. You’ll find AC on home charging wall boxes.


Alternatively Fuelled Vehicles run on fuels that aren't the traditional petrol or diesel.


This is when a car has self-driving technology. Tesla is one of the most famous electric cars to incorporate this type of technology with its Autopilot system.


Acoustic Vehicle Alerting Systems generate an artificial noise in electric cars so that pedestrians and cyclists can hear them coming. The AVAS will make a sound when the car is reversing or is travelling slower than 18.6mph (30km/h).

Battery Capacity

This is the amount of power that an electric car’s battery can hold. Over time, the battery capacity of your car will decrease.


Business Contract Hire is a type of leasing contract for businesses rather than individuals. See our guide on finance options here.


Battery Electric Vehicles are another way of saying fully electric vehicles. These are cars that are powered solely by a battery and do not require petrol or diesel like hybrid cars do. 


Benefit-in-kind is a tax on employees who receive benefits or perks on top of their salary. If you have a company car for private use, you will need to pay a BIK contribution or company car tax.

Brake Recuperation

This is when power is recycled back into the battery when you brake. Brake recuperation can turn what would have been wasted kinetic energy into useful electrical energy. This process is also called regenerative braking. See our article for more information.

Car Club

Car clubs are a car-sharing scheme that often take place in city areas. A resident rents a car by the hour and then returns it to a dedicated parking spot.


CCS stands for Combined Charging System and is the standard for charging electric vehicles in the EU. Its layout consists of two DC pins that sit below the standard Type 2 connector plug.


Lots of cells combine to make a battery pack that can store lots of electrical energy.

Commando Cable

This is the name given to the wire that connects your car to the charging point via connectors.

Connector Type

These are the ‘plugs’ that sit at the end of the commando cable. They come in different types and attach your electric vehicle to the charge point.

Cost per kWh

Cost per kilowatt-hour is the electrical equivalent of the price you'd pay for a litre of petrol or diesel. To calculate the charging costs of an electric car, multiply the cost of electricity per unit (kWh) by the battery capacity of the vehicle in kW.


A Continuously Variable Transmission is a type of automatic gearbox that is common on hybrid vehicles.


Direct Current is a type of electricity flow that can charge electric vehicles at faster speeds. Electric cars have to convert AC power from the mains into DC before they can store it in the battery and this process takes extra time. DC charging stations cut out this process by providing DC power straight to the battery.


An electric car’s battery will lose capacity over time, much like the battery on your mobile phone. This will happen naturally as they get recharged numerous times, other factors like the temperature can also have an impact.


The amount your car drops in value as it gets older.

A Hybrid Electric Vehicle is a petrol or diesel car that also has a small electric motor and battery. HEVs don't have a plug, instead, they get their power from the engine or through regenerative braking.

Home Charging Point

Home charging points make owning an electric car much easier. Usually, they'll come in the form of a wall box that's installed in your garage or near where you park your car.


Hybrid cars come in many shapes and sizes. They combine either a petrol or diesel engine with an electric battery and motor to create a vehicle that emits less carbon dioxide. Plug-in hybrids contain a bigger battery and can be recharged.
