Alternatively Fuelled Vehicle. A car that runs on fuel other than traditional petrol or diesel. See also PHEV, EV, BEV, FCEVS, HEVs.
Air Conditioning. Keeps you cool in summer and helps demist faster in winter. It takes power from the battery in an electric car though, so it’ll have a small impact on the range.
An Australian rock band or types of electricity flow, depending on how you spent your youth. See both AC and DC.
Acoustic Vehicle Alerting System. This is the artificial noise generator fitted to electric vehicles to help pedestrians and cyclists hear them coming. They range from a simple note to chimes developed by famous record producers.
A monthly payment to use the battery in an electric vehicle. This makes the car cheaper to buy and comes with a battery guarantee. Common on older Renaults but has been phased out on new cars. Beware of it if you are buying used though, as it's a right pain in the paperwork.
Battery Electric Vehicle. A car (like the BMW i3) that gets its power solely from a battery, which is charged by plugging it in. When the battery runs out it won’t go any more and it doesn’t emit any emissions.
Benefit in Kind. Not a cheap ballpoint pen. It's a form of income tax levied on company car users which is much lower for electrified cars and doesn’t cost a penny for electric car drivers.
The amount of power a battery can hold. This reduces over time, but as with any car, an EV comes with a standard warranty. But you also get a longer one for the battery which is normally guaranteed for 8 years.
Big Evil Grin. The look on Ginny and Nicki’s face when they launch a Tesla in Ludicrous Mode. See ‘Ludicrous Mode’.

The amount of electricity which can be squeezed into a battery.
Cost per KwH
Cost per kilowatt hour. Think of this like the price you pay for a litre of petrol or diesel. So to work out the charging costs of an electric car multiply the cost of electricity per unit (kWh) by the battery capacity of the model in kW.
The individual parts of a battery which combine to make the whole pack. Or where you’ll end up if you try and show off a Porsche Taycan’s acceleration on the public road.

Carbon Dioxide. A gas is produced when burning fuels which causes global warming. The amount of CO2 a car produces is measured and taxed.
The suspension setting used by a Tesla just before it launches in maximum-attack acceleration mode. Not to be confused with a 1998 hit single by Neneh Cherry.
Heating and air conditioning inside a car.
Direct Current. This is the other half of AC and is a faster type of electricity flow when charging electric cars. An electric car has to convert power from the mains socket from AC to DC before it can be stored in the battery, which slows the process. Rapid chargers speed it up by providing a DC flow directly from the charging unit.
Batteries slowly lose their capacity over time as they’re used more, this is degradation. How often they’re charged and how hot or cold they get can also have an impact.
The amount a car’s value drops as it gets older. See also Residual Value.
The common term for charging your electric car away from home.
An unexpected and usually hidden feature in a car’s software which owners enjoy finding. Commonly found in Tesla models. Can also refer to oval shaped confectionery which is gifted in large quantities around spring time religious festivals to people who write a helpful dictionary about EVs. Please.

Electric Vehicle Homecharge Scheme. This is a grant from the nice folk from OLEV which provides £500 off the cost of buying & installing a home charging point like the ones from BP Chargemaster.
Ginny’s favourite part of the Nissan Leaf. This allows you to slow the car down and accelerate using a single pedal so the car can get extra energy from regenerative braking.
EPA stands for the Environmental Protection Agency, an organisation from the US which conducts independent testing of car efficiency. Its figures are generally closer to what you'd expect in the real world than the WLTP numbers used in the UK and Europe, but not all cars sold here are tested.
The Electrifying Efficiency Rating (or E-Rating for short) is an industry standard score to measure the overall efficiency of electric cars. It uses an algorithm taking into account a number of factors, including how well the car converts electrical power into miles on the road, speed of charging, power saving gadgets and real-world consumption. More details can be found here.
Fuel Cell Electric Vehicle. This uses hydrogen gas as a fuel. They typically have a range of around 300 miles and or more and only emit water vapour from the exhaust. Charging is limited at the moment and there are only a couple of Fuel Cell cars on sale like the Hyundai Nexo, but you’re going to be hearing a LOT more about them in the future.
A charging speed of 7kW - 22kW, which will typically charge an EV in three to 10 hours. This type of charging point is usually found in homes, workplaces and in some public places.

See ‘ICEed’, ‘ICEing’ and ‘ICE blocked’.
Also known as the ‘J plug’. This is a type of charging connector mainly used in North America and Japan.
Kilowatt. This is a measurement of power, in a petrol or diesel car if 50mph is your speed then you have to maintain that for an hour to travel 50 miles. In an electric car 40kW is how much power you’re using and you’ll have to maintain that consumption for one hour to use 40kWh.
KiloWatt Hour. It’s a unit for measuring how much electricity (or energy) you’re using and the size of a battery is measured in kiloWatt hours. For example the least expensive battery on the Volkswagen ID.3 is 48 kWh, which means it can store a maximum of 48 kilowatt hours of electricity. It’s time to stop thinking about your miles per gallon (MPG) and start thinking about ‘miles per KwH’.

Road Fund Licence. Previously known as the ‘tax disc’. A fee payable to the government to use the roads in the UK. Not to be confused with rugby.
Cards (and keyfobs) used by many older charging points to allow access to EV charging ports. As contactless payment comes in these will no longer be needed.
A charging speed of 3.7kW which usually charges up an all electric car in 6-12 hours and a plug-in hybrid in 2-4 hours. It’s slow, but still provides faster charging times than a 3-pin socket and is the typical speed of older charging points.
Second Use Battery
Used power packs from electric cars which have been reused for other purposes, such as electricity storage in homes and electricity grids.
There’s no such thing as a free lunch. And the same applies here, this is marketing talk for a Hybrid Electric Vehicle. It’s a petrol or diesel car that also has a very small battery which can’t be plugged in and it gives you no emission free driving. See ‘LOL’.
A system controlled by your energy provider that automatically charges your EV less when electricity is expensive and increases the charging when it’s cheap. The bonus is that cheap electricity often corresponds to times when there’s plenty of renewable energy available. Which is something we like a lot.
An electricity meter in your home which is connected to the internet and can be used to charge electric cars at the cheapest time of day.
State of Charge. The percentage of power in a battery. Details of how to check your state of charge are usually in the owner’s manual.
Tesla’s dedicated rapid chargers. The envy of all non-Tesla electric car owners.
Solid State Battery
It might sound like a German techno rock band, but it's actually a new type of battery which promises more capacity, faster charging and longer life. It's not yet ready as boffins are a bit baffled and can't get the electrodes to last longer than a few years. Once it's fixed, it will really make EVs the logical choice for everyone.
Total Cost of Ownership. Takes into account fuel/charging, tax, servicing, depreciation.
The government’s £320 per year supplementary road fund licence charge for non-BEV cars which have a list price of more than £40,000. So called because it originally hit Tesla buyers the hardest, but 100% battery cars have since been exempted. It still applies to hybrids though.
Fans of Tesla products. Known for reacting passionately on social media if you say dare to criticise their beloved cars. Or their leader. Sorry, Elon Musk.
A type of plug. See Granny Charger. Can also describe the sharp objects you usually find in a new shirt the first time you wear it.
The term used for slowest type of charging, either from a de-rated dedicated chargepoint or through a standard domestic 3-pin plug (which lacks certain safety features and is best used only in an emergency).
A charge cable which is fixed at one end, either to the car (as with a Renault Twizy) or to the charger (as with rapid charge points).
A ‘limping’ mode for electric cars when they have only a few metres of power left, which is used to get the car to a place of safety, such as off the road.

A five pin charging plug that also features a clip and is typically found on older EVs.
A seven pin charging plug with one flat edge, which was originally favoured by European brands e.g. BMW, VW and is now becoming the most popular on all cars.
Time of Use
The time you use your electricity. If you choose the right tariff, you can choose to use the most power when there’s less demand on the Grid and prices are lower. This is perfect for charging an electric car.
Type of Use
How the electricity is used in your home or business. Different types include cooking, heating or charging your car. Energy providers can alter the cost for certain types.

Ultra Low Emission Vehicle. A car that uses low-carbon tech and emits less than 75g of CO2/km from its exhaust, making it eligible for grants and benefits from the UK government.
Vehicle to Grid. A cool way to make money from your car. This uses your electric car battery to release power back through the charger either for use in your home or you can sell it back into the grid at large during times of high demand. It’s currently offered in the UK by OVO Energy and the Nissan Leaf is one of the few cars currently clever enough to do this.
Vehicle to Home. As with Vehicle to Grid, but the car can only be used to power your home rather than feed power back into the wider grid. Useful in a power cut. As are candles.
A measure of the power of electricity. The higher the voltage, the more powerful the car. Porsche’s Taycan uses an 800 volt system for example, allowing it to be fast and very quick to charge.
The Worldwide Harmonized Light vehicles Test Procedure. An improved emissions and efficiency testing regime which is meant to give a more realistic version of a cars range or fuel efficiency. Although we think it’s generally still pretty optimistic.
Charge points provided by your employer.
You Only Live Once. As does the planet. Make it count.
Zero Emission Vehicle. A catch-all term for a car that doesn’t produce any CO2.
An engine, motor, process, or other energy source that emits no waste products that pollute the environment or damage the climate.
