A-Z Glossary of Electric Vehicle Terms

A

 

Alternating Current (AC)  

Alternating current (AC) is a form of electric current. To store energy in an electric vehicle (EV) battery, AC must be converted to direct current (DC). A converter in the car facilitates this conversion, enabling storage in the battery. Being reliant on this conversion process, AC charging is slower than DC charging.

Learn more about alternating current (AC).

 

Amps

Amperes, often abbreviated as “amps” is the unit of electric current. In EV charging, the charger’s amperage determines how quickly it supplies power to the vehicle’s battery. Amperage rates for electric car charging vary based on the charger type. Home chargers typically range from 16 to 32 amps, with higher amperage resulting in faster charging.

Learn more about amps.

 

Alternative Fuel Vehicle (AFV)

An alternative fuel vehicle (AFV) is any vehicle not powered by conventional diesel or petrol. Common options include hybrids, plug-in hybrids, and electric cars.

 

B

 

Battery Electric Vehicle (BEV)

A battery electric vehicle or ‘BEV’ is a fully electric vehicle with a rechargeable battery and no internal combustion engine. It runs entirely on electricity, not petrol or diesel. These vehicles are charged by an external electricity supply, such as plugging into an EV charge point.

 

Benefit in Kind (BIK)

Benefit in kind (BIK) refers to perks provided by employers to employees that are separate from their salary. Some BIK perks are tax-free, while others incur taxes. Often termed company car tax, employees using a company car for personal use pay BIK tax from their monthly wage. The BIK rate for zero and low-emission vehicles is currently 2%, fixed until April 2025. This rate is significantly lower than rates for petrol and diesel vehicles.

Learn more about electric vehicle benefit in kind (BIK).

 

Battery Capacity

Battery capacity, measured in kilowatt-hours (kWh), represents the energy contained in an electric vehicle’s battery pack. It indicates how many miles you can drive on a full charge. Higher kWh means greater driving range on a single charge. Think of it as the gas tank size of a gasoline-powered vehicle.

 

Battery Management System (BMS)

A Battery Management System (BMS) manages the electronics of a rechargeable battery in an electric vehicle. A BMS is crucial in ensuring electric vehicle safety as it protects the battery from misuse and damage, prolongs battery life and ensures that the battery is always ready for use. As the battery is the most expensive component of an electric vehicle, the role of the BMS is pivotal.

 

C

 

Charging Rate

An electric vehicle’s charging rate, usually measured in kilowatts (kW), indicates how fast its battery can charge. Different cars have different maximum charging rates. For example, some max out at 7kW, so using a more powerful 22kW charger won’t speed up the process.

Likewise, a charger’s charging rate refers to its maximum power output for charging a vehicle’s battery, measured in kW. This rate varies depending on the charger type. For example, a 60kW rapid charger charges faster than a 7kW one.

 

Combined Charging System (CCS)

Combined Charging System (CCS) is a rapid-charging connector type. It is designed for direct current (DC) rapid charging at public locations, not alternating current (AC) home charging. If your electric vehicle is a European or North American model, it probably has a CCS socket.

 

Charging Point

A charging point is a device that uses electricity from an electric grid to charge electric vehicles and plug-in hybrids. You’ll find charging points at home, in public spaces, or workplaces. They are often referred to as EV chargers, electric car chargers, EV charging stations, or electric vehicle supply equipment (EVSE).

 

Connector Type

Electric cars use a cable with connectors on each end to charge: one for the car and the other for the charge point. Various connector types accommodate different vehicles and charging methods. CCS or CHAdeMO connectors are common for rapid and ultra-rapid chargers, while fast chargers typically use type 1 or type 2 connectors. Ensure compatibility by matching your connector type with your vehicle’s socket, as connector preferences may vary by country.

Learn more about EV charging connector types.

 

CHAdeMo

CHAdeMO was the original rapid-charging connector type for electric vehicles and plug-in hybrids, originating in Japan. But, in the UK, only a few EV models still utilise this connector type, as European carmakers favour Combined Charging System (CCS). CHAdeMO charging is capable of handling charge rates of over 400kW.

 

Cost Per kWh

Electricity usage is measured in kilowatt-hours (kWh). The cost of charging an electric car at home fluctuates depending on the current cost per kWh. Think of it like calculating the cost of a litre of petrol or diesel. To determine the charging costs of an electric car, multiply the electricity cost per unit (kWh) by the model’s battery capacity in kW.

 

Charge Point Operator (CPO)

A Charge Point Operator (CPO) is an organisation responsible for installing, managing and maintaining electric vehicle (EV) charging infrastructure.

 

Connector

A connector is the part of a charging cable that links one end to the electric vehicle’s charging port and the other end to a charging point. A connector can also be referred to as a ‘plug head’.

 

Charging

Charging refers to the process of replenishing an electric vehicle’s battery with electrical energy from an external power source, such as a charging point.

 

Charge Scheduling

Charge scheduling allows you to plan your home charging to a more convenient time of the day. You can remotely schedule a charge using your home charger’s smartphone app. With this feature, you can choose the exact time you want your vehicle to start and stop charging.

 

Clean Air Zone (CAZ)

A Clean Air Zone (CAZ) is a designated area within a city or town where certain vehicles must meet specific emission standards to enter. Non-compliant vehicles are subject to a daily charge. This charge incentivises owners to upgrade to compliant vehicles. CAZs are usually situated in areas with significant air quality issues. The goal is to decrease vehicle pollution and encourage greener transportation options like public transport and low or zero-emission vehicles.

Learn more about Clean Air Zones (CAZ).

 

Charging Cable

A charging cable is used to charge an electric vehicle, connecting one end to the car and the other to a charging point. It consists of three parts: a connector for the car, a length of wire, and another connector for a charging point. Available in various sizes, like 5 or 10 meters, one is typically provided with your electric vehicle. Charging cables can also be permanently attached to a charging point, referred to as being ‘tethered’ to the charger.

 

Congestion Charge

The London Congestion Charge zone is an area in London where driving incurs a charge unless eligible for a discount. Managed by Transport for London (TfL), it aims to decrease city centre traffic and air pollution while aiding London’s shift to carbon neutrality by 2030. Vehicles failing emission standards pay a fee upon entry. Battery electric vehicles (BEVs) are currently exempt. But, starting December 2025, all electric vehicles must pay unless qualifying for an alternative discount.

Learn more about the Congestion Charge.

 

Current Transformer (CT Clamp)

A CT Clamp is a current transformer that clamps around a cable to monitor the load (amps) in your house. It serves as a safety measure by reducing the charge rate on your charger if it detects a load nearing the house’s maximum capacity, preventing blown fuses.

Also, with a CT clamp, you can use solar features if your EV charger supports them. This is possible because the CT clamp detects the energy exported to the grid from solar panels, allowing you to use excess solar energy to charge your car for free instead of exporting it.

 

D

 

Direct Current (DC)

Direct current (DC) is a type of electric current that can directly charge a battery without needing conversion, unlike Alternating Current (AC). This feature enables faster charging speeds, making DC energy the choice for rapid and ultra-rapid charging.

Learn more about direct current (DC).

 

Destination Charging

Destination charging is the process of charging your electric car while spending time at locations and attractions. Destination charge points are typically located in areas that are considered the final destination of a driver’s trip, such as supermarkets, restaurants and hotels.

 

Degradation

Degradation refers to the gradual decline in an electric vehicle battery’s efficiency, leading to reduced energy capacity, range, and power over time. Although it typically takes many years, preventive measures are available to minimise battery degradation.

Learn more about how to minimise battery degradation.

 

Distribution Network Operator (DNO)

A Distribution Network Operator (DNO) distributes electricity from the national grid to homes and businesses in their area. They also manage infrastructure such as towers, transformers, poles, cables, and meters. Before installing an EV charger, approval from the DNO in your area is required.

Learn more about the Distribution Network Operator (DNO).

 

Dual Charging

Some EV chargers offer dual charging, allowing you to charge two vehicles simultaneously from a single charging unit.

 

E

 

Economy 7

Economy 7 is a special energy tariff with two different daily prices: a standard rate and a cheaper rate for a 7-hour overnight period. This allows you to pay less for energy used at night and more for daytime usage. Utilising this tariff can benefit EV owners, as charging overnight at a cheaper rate can result in cost savings.

 

Earth Bonding

Earth bonding involves connecting all metallic objects, like metal gas and water pipes, in a property to an ‘electrical earth’ system. This process ensures that electricity can safely flow back into the ground if there’s an unusual current. In simpler terms, it prevents electric shocks by ensuring metallic objects don’t become ‘live’ due to faults in electrical appliances. Water and gas bonding in your property is necessary for a safe EV charger installation, except when the supply pipes are plastic.

Learn more about earth bonding for an EV charging point installation.

Learn more about kilowatts for electric cars.

 

Kilowatt-hour (kWh)

A kilowatt-hour (kWh) measures an appliance’s energy use over time. In electric vehicles, it represents the battery’s capacity, indicating how much energy the vehicle can store in its battery. Electric car batteries are typically measured in kWh. For instance, the Nissan Leaf has a battery capacity of 40 kWh.

Learn more about kilowatt-hours for electric vehicles.

 

L

 

Lithium Ion

Most electric vehicles (EVs) use lithium-ion batteries for their motors. These batteries store energy for movement. Compared to lead-acid batteries, lithium-ion ones are lighter, more energy-dense, and last longer. An EV’s lithium-ion battery is not a single unit. Instead, it is made up of many stacked cells. The more cells, the higher the battery’s capacity, measured in kilowatt-hours (kWh).

 

Load Management

Load management is a safety feature in chargers that regulates the energy provided to a vehicle. It monitors your home’s total electrical load and adjusts the power drawn by the EV charger to ensure efficient allocation of available power. For instance, if many appliances run simultaneously, it may pause or reduce the charging process to prevent overloading and potential fuse blowouts.

 

Level 1, 2, and 3 Charging

Electric vehicle charging is categorised into three levels: 1, 2, and 3, each offering progressively faster charging speeds.

Level 1 charging, considered “slow charging,” utilises a granny charger (rated at 2.3kW) or a home charger (rated at 3.6kW), operating on alternating current (AC).

Level 2 charging, often used for daily charging, is available at homes, workplaces, and public areas like supermarkets. These chargers, rated from 7kW to 22kW, are termed “fast charging” and operate on alternating current (AC).

Level 3 charging, known as rapid charging, uses direct current (DC) power and is typically found in public locations like motorway services. These chargers, rated upwards of 43 kW, cannot be installed at home.

 

Looped Supply

A looped supply is when two properties share a single electricity service cable, often found in terraced or semi-detached homes. Inspect your electricity meter box for two service cables entering the meter to check if you have a looped supply. If identified, inform your EV charger installer, who will notify your distribution network operator (DNO) before installation. This allows them to disconnect each meter connected to the shared loop, as EV chargers are typically not permitted on looped supplies.

Learn more about looped supplies and distribution network operators (DNO).

Wattage

Wattage indicates the power consumption of an electric device, measured in watts, with 1000 watts equalling one kilowatt. EV chargers come with varying power ratings; for instance, a typical home EV charger is usually rated at 7,000 watts (7kW). Higher wattage translates to more power, resulting in faster acceleration for electric vehicles or quicker charging at a charge point.
