It seems a bit wrong to actually use an acronym in the title of the section to explain all the acronyms, but I'm hoping that EV is understood to be electric vehicle.  I may not manage to cover absolutely every acronym that's being used, but please do let me know if there's any you think I've missed.

A 

• AC - when referred to charging, this is the Alternating Current used in domestic power supplies.

 B

• BEV - Battery Electric Vehicle: a car or other vehicle whose only means of propulsion is a battery powered electric motor.
• BMS - Battery Management System: a controller in the car that manages charging and discharging rate based on battery voltage and temperature.

C

• CCS - Combined Charging System, the most popular DC charging method in the UK and the rest of Europe.
• CHAdeMo - Contraction of CHArge de MOve, CHAdeMo is a fast (DC) charging technology. 
  The expression finds its roots in the following Japanese sentence: “O cha demo ikaga desuka”, which translates into “would you like a cup of tea?”. The reference to tea is here to remind us that it takes very little time to charge the battery of a CHAdeMO vehicle. This might be seen as a bit of a joke, given it is the slowest of the DC charging methods.
• CPM - Charging Point Manager: This refers to a type of software responsible for smart charging, i.e., allocating power to different electric vehicles to make sure that each one charges as quickly as possible. It relies on customisable algorithms to work efficiently.
• CPO - Charging Point Owner: A CPO is an operator who owns and oversees the operation of electric vehicle smart charging points.

D

• DC - when referred to charging, this is the Direct Current used in delivering rapid charging at public locations.
• Destination Charger – an AC charger (where you will require you're own charging cable) at a location where vehicles will typically charge for a long period and can be left plugged in, such as at shopping centres, hotels or theme parks.
• DLM - Dynamic Load Management refers to an EV charging technology that makes it possible to evenly distribute the electricity to all the vehicles that might be plugged simultaneously. In other words, DLM optimises charging speed and prevents all grid congestion episodes.
• DSO - Distribution System Operators are the operating managers and/or owners of energy distribution networks.

E

• EMP - Electro-Mobility Partner: An EMP is a company that provides customers access to an electric vehicle charging network. They will often offer a tracking service such as an app for evaluating the availability of charging stations. EMPs are also responsible for determining the price of electric vehicle charging.
• EV - Electric Vehicle: EVs are equipped with a battery-powered motor instead of a traditional internal combustion engine. Contrary to PHEVs and HEVs, EVs do not have a gasoline tank and output zero tailpipe emissions. They are associated with a lower carbon footprint than traditional vehicle types.
• EVSE - Electric Vehicle Supply Equipment: EVSE refers to equipment that exists to supply electrical energy for charging electric vehicles. It can be residential (such as an at-home charger) or commercial (such as chargers at malls, workplaces, rest stops, etc.).

F

• Fast Charger - an AC charger (using your own cable) that typically charges at speeds between 7kW and 22kW.  The name is misleading, because this is actually slow compared to rapid chargers.  The name originated from the fact that they are faster than charging with a three pin 'granny cable' plugged into a domestic socket at about 3kW.  Some older EVs will actually be limited to about 3.6kW even with a 'fast charger'.
• FCEV - Fuel Cell Electric Vehicles:  FCEVs are reliant on fuel cell batteries in conjunction with their electric motor.  The fuel cell runs off of hydrogen energy.  The process of getting hydrogen to a filling station (the complete cycle) is currently inefficient and there are just 12 public hydrogen filling stations in the UK, down from a peak of 15.

G

• GHG - Greenhouse Gas: Greenhouse gases are gases in the atmosphere that trap the sun’s heat and warm the Earth, contributing to climate change. The Earth’s most common greenhouse gases are ozone, nitrous oxide, water vapour, methane, and carbon dioxide. Cars with internal combustion engines emit greenhouse gases through their tailpipe.
• GoM - GuessOMeter: the range predictor on your EV.  It is referred to as the GoM due to the inaccuracy of many of the readings.
• Granny Charger - this is a common name given to a charging lead that uses a three pin plug and typically charges at around 3kW.

H

• HEV - Hybrid Electric Vehicle: HEVs use both electric batteries and a petrol or diesel engine. More often than not, the electric motor is here to assist the internal combustion engine, such as during acceleration phases. Note that HEVs cannot be plugged into regular EV charging stations. Batteries replenish themselves via the energy generated by the combustion engine or via regenerative braking.  Some manufacturers describe these cars as 'self-charging' in an apparent attempt to make them sound better than plug in hybrid vehicles (PHEV), but PHEVs can also 'self-charge' and this method of creating the electricity is not as efficient as plugging into an external power source.

I

• ICE - Internal Combustion Engine: Internal combustion engines use liquid fuel (gasoline) to create energy to power traditional vehicles. ICE cars are the most common vehicle on the road, but an increase in EV infrastructure is making electric cars more accessible.
• ICEd - basically describes a charging location or bay that is blocked by an internal combustion engined vehicle (ICEV).
• ICEV - Internal Combustion Engined Vehicle.

K

• kW - Kilowatt: kW is a measurement unit used to determine how much power an electrical appliance consumes.  In EV terms, kW is used to show two things; the power of the electric motor and the speed at which the batteries can be recharged.
• kWh - kWh defines the amount of energy that is required to power an electrical appliance for one hour.  In EV terms, KwH is used to confirm the size of the battery in the vehicle.

M

• MHEV - Mild Hybrid Electric Vehicle: A mild-hybrid car (often referred to as MHEV) works largely the same as any normal combustion-engined car.  The difference here is that manufacturers will typically add a smaller battery to an existing engine in order to boost efficiency and cut emissions.  This tends to work by allowing the engine to cut power earlier when coming to a stop, allowing start/stop systems to keep the engine off longer and sometimes even offer an electric-only boost when pulling away.  MHEVs cannot be driven using the electric motor on its own, so the internal combustion engine (ICE) is always in use when driving and is always producing emissions.
• MpKwh - Miles per kWh: this is the measure of vehicle efficiency; how far you car can be driven per kWh of energy.  Most cars have an MpkWh figure of around 3 to 4, which will vary dependent on driving style and weather.  Larger inefficient vehicles, such as SUVs, vans and pick-up trucks are likely to have lower numbers (less than 3).  The most efficient cars will achieve higher than 4 mPkWh.

P

• PHEV - Plug In Hybrid Vehicle:  PHEVs use both electric batteries as well as a petrol or diesel engine to power the vehicle.  These vehicles run on electrical power until the battery is depleted and automatically switch to the Internal Combustion Engine (ICE).  PHEVs can also be plugged in to domestic or public chargers to add charge to the batteries.  As a result, many PHEV drivers can actually manage most of their journeys without using the ICE.

R

• Rapid Charger - rapid chargers are DC chargers where the charging cable will be heavier and tethered to the charging unit.  Some early units were rated at 50kW, increasing to 75kW or higher subsequently.
• RFID - Radio Frequency Identification:  RFID is a type of technology that links a card to an account. It can be used in electric vehicle charging to quickly and conveniently start a charge through tapping.
• RxEV - Range Extending Electric Vehicle:   This acronym is relatively uncommon, especially as the main popular RxEV (the BMW i3 Rex) was discontinued in favour of adding a larger battery. RxEVs have a relatively small battery and also have an Internal Combustions Engine (ICE) that can recharge the batteries.  Unlike PHEVs, the fuel-driven generator does not power the car on its own so cannot be directly connected to the wheels.  Modern black cabs built by LEVC are now the most common vehicle to use an RxEV setup.

S

• Slow Charger - a charging lead that uses a three pin plug and typically charges at around 3kW; sometimes referred to as a 'granny charger'.
• Smart Charger - this is the name given to a fast charger that is connected to the internet via wifi or cellular connection.  They can be programmed to charge at certain times or limit charge rate via an app.  All new domestic chargers in the UK have to be Smart Chargers by law.
• SoC - State of Charge: this is the amount of energy stored in your EV's battery at a given point in time, usually shown as a percentage figure.
• SoH - State of Health: this is the  amount of usable capacity remaining in the battery compared to the capacity when new.  This is usually expressed as a percentage, and would typically need a special tool plugged in to retrieve the reading.
• Supercharger - the name given to the Tesla charging network.

T

• TSO - Transmission System Operator: TSO is a term defined by the European Commission that describes an organisation in charge of transporting energy and maintaining the infrastructure for transporting energy.
• Type 1 - this relates to the cable for 'fast' AC chargers on some early EVs.  They are most commonly found on Mk1 Kia Soul EVs and the older Nissan Leafs and PHEVs like the Mitsubishi Outlander.
• Type 2 - this relates to the charger / cable for 'fast' AC chargers.  These are the connectors used on most home chargers and destination chargers.  They are typically 7kW (single phase 32A), 11kW (3 phase 16A) or 22 kW (3 phase 32A).  There are a few 43kW chargers around (3 phase 63A), but these can only be used by some Renault Zoes. AC chargers use actually use an onboard charger in the vehicle to convert AC to DC and charge the battery.  Most cars can can only charge at 7kW, although 11kW is becoming more common.  A few newer cars and vans have 22kW or as an option.

U

• Ultra Rapid Charger - this relates to a rapid charger with over 100 kW power, some as high as 350kW.  Some ultra rapid chargers are 800V but have current limits that produce lower than expected kW rate on 400V vehicles, which is most EVs.  As a result, a 120 kW rated 800V charger might only deliver 70kW on a 400V car.

V

• V2B - Vehicle to Building:  Vehicle-to-building is a technology that lessens a building’s energy consumption by drawing on the untapped energy of multiple idle electric vehicles.  I have seen cases where EV drivers have powered their homes or businesses during power cuts.  There are also examples of caravanners who have powered their caravan using this technology whilst camping 'off-grid'.
• V2G - Vehicle to Grid:  V2G is a new smart charging technology that can push the energy stored in electric cars’ batteries back to the power grid.  As we’re increasingly relying on renewable energies to power the grid, V2G is the technology that will stabilise the grid when the energy produced via renewable solar or wind sources can’t meet the demand.
• V2H - Vehicle to Home: A technology that allows the battery of an electric vehicle to power an entire home (or other building of similar size). This is a bi-directional system with the power to convert energy between AC supply and electric car battery.
• V2X - Vehicle to Everything: A technology that allows the battery of an electric car to provide general backup power in the case of an outage.
