With the rising popularity of electric cars, more people continue to make the switch from their regular cars. However how many of these actually understand EV terms. That's why we compile here the list of most common EV terminology for your reference!

The era of the electric vehicle is truly here, and we are not talking of just Tesla EVs here.. We have become very familiar and comfortable with a car powered by a battery, and what it could all entail. With the rise and rise of EV, comes new technology, support devices and services, and of course language.

Knowing the usual terms and jargon associated with EVs mean you are that much less in the woods, as regards this innovation. Here is a compilation of the most common EV terms you should know, brought to you by Naijauto team!

1. EV - Electric Vehicles

Stands for “Electric Vehicle.” This is an umbrella category that packs in all cars that are entirely powered by Electricity or have both an Electric Motor as well as a petrol engine in a hybrid system.

2. AC - Alternating Current

Typically you may call this ‘air-conditioning’ in a regular car, but that is not the first meaning in an electric vehicle. This means “Alternating Current.” It’s a charge of electricity that frequently changes or alternates in direction. AC is the kind of power that originates from the power plant for homes and businesses.

3. AER - All Electric Range

This is “All-Electric Range.” This is the status of any EV when exclusively using electricity.


If someone says "AER" in regards to an EV, would you understand what they mean?

4. AH - Amp Hours

This means “Amp Hours”. It is usually present with a number in front of it, e.g., 320 Ah. A battery’s capacity is generally calculated using amp hours.

5. Battery Management System

This is an electronic system that is inside the Vehicle, and that coordinates and guards the battery.

6. BEV - Battery Electric vehicle

Stands for “Battery Electric vehicle.” It is also known as an “All-electric” vehicle. BEVs utilize energy that is warehoused in rechargeable battery packs. BEVs usually obtain their power from the batteries, and so must be plugged into an outside power source for charging.

7. CCS - Combined Charging System

This is an alternative technique to charge electric vehicles quickly from a unique electric connection. CCSs often use the SAE J1772, which is best for North American electrical mode for Electric Vehicles.

8. CCID - Charge Circuit Interrupting Device

This is a safety defense module within an EVSE that decreases the possibilities of a person receiving an electric shock.

9. Charging Station

It is the location(s) where EVs can be plugged in and charged; it could be at home, work, or in any publicly accessible area.

10. Connector

This is a device fixed to the cable from an EVSE (Electric Vehicle Supply Equipment) that is attached to an EV, and that permits it to charge.

11. Chademo Plug

This rapid charging method allows for charging capacities of up to 50 kW at the right charging stations, which can be a public one. You can find compatible Chademo plug for electric cars in brands such as Toyota, BD Otomotive, Kia, Mazda, Citroën, Honda, Subaru, Mitsubishi, Nissan, Peugeot, and Tesla, which comes with an adapter.

12. Direct Current

This is an electric current of continuous direction, which usually comes from a battery.

13. DC fast charging

The high powered method to charge EVs quickly with an electrical output alternating from 50kW – 120kw. It will completely charge an average EV within 30 to 40 minutes.

14. EREV - Extended-Range Electric Vehicle

Though the electric motor of a PHEV often drives the wheels, EREVs features a supplementary power unit; usually an inner combustion engine, that serves as a generator to recharge the battery while it runs out.

15. EVSE - Electric Vehicle Supply Equipment.

It is a dedicated protocol or procedure that enables two-way communication between a charging station and an electric vehicle. Fundamentally, it channels the safe current stream between the charger and your EV. Sometimes, it is also called a charging station.

16. EVB - Electric Vehicle Battery

It is a battery that is used to control or power the movement of a BEV (Battery Electric vehicle).

17. FCEV - Fuel Cell Electric Vehicle

This is a car that uses a fuel cell, though, it could be a hydrogen-based; it helps produce electricity that runs an onboard motors.

18. GHG - Green House Gas

A gas, like Carbon Dioxide, that adds to global warming through the emission of infrared radiation.

19. HEV - Hybrid Electric Vehicle

A car that integrates a secondary battery and an electric motor to improve the effectiveness of the engine. The battery’s charge is continuously an Internal Combustion Engine or ICE, and it can’t be charged by being plugged into an electrical supply. Hybrids usually bring more excellent fuel economy than an ICE, but can only travel for minimal distances on electrical power alone.

20. ICE - Internal Combustion Engine

It is powered by flammable fuel, regularly a regular gas product or petroleum.

21. KW - Kilowatt

It is used as a measure of electric power.

22. Level 1 Charging

This has to do with you charging your EV using a conventional home outlet that is up to 120v. Level 1 is the slowest way of charging your EV and it possibly can take up to 24 hours to fully charge.

23. Level 2 Charging

It charges your EV at 240v utilizing an installed outlet. It is the most recommended method and depends on your EV type and charger.

24. Level 3 Charging

It is the fastest method of charging for all EVs because it can charge-up an EV in half an hour. The chargers that are used for this level are specially made. This kind of charging is also expensive as the chargers need more power.

25. NEV - Neighborhood Electric Vehicle

They are BEV’s that are only meant for streets as they come with low speed restrictions, usually around 45mph. NEVs are all-electric, and can be re-energized using a standard outlet.

26. VRLA battery - Valve-regulated lead-acid battery

It is a chargeable lead-acid battery.

27. V2G - Vehicle-to-Grid

It is a system that permits EVs to connect with the power grid to sustain the movement of electricity on either route.

Now you are familiar with EV-speak, you can talk like an expert.
