EV Dictionary

This is your dictionary to all words you need to know of when buying an electric vehicle. This dictionary will be a work in progress.

A

AC – Alternativ Current

Alternating current is the most commonly used electric current. This is what common households and businesses get. When you plug anything into your power outlet at home, it will be AC.

In more technical terms:

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. Wikipedia, 2020

AMP – Ampere

Simple said the ampere is just a unit of measure. Like volts, kilowatts, horsepower, centimeter and so on. Ampere is often shortet to just amp. In more technical terms the amp is a measure of the electromagnetic force between conductors carrying electric current.

B

BEV – Battery Electric Vehicle

BEVs are 1000% battery-driven electric vehicles. So in general terms also what we just call EVs. Some people will call them BEV, mostly because there are hybrid vehicles as well which in principle are electric vehicles.

C

Charging

Filling the battery with electricity.

Charging point

A location where you can plug your electric vehicle into a public accessible charging station.

Charging station

Also known as EVSE (Electric Vehicle Supply Equipment), this is a station which has the equipment to charge your EV. These stations can be either a level 1, level 2 or level 3 charging station. You can read about the different levels of charging stations here: is-fast-charging-bad

Connector

D

DC – Direct Current

DC or Direct current, also known before as galvanic current, is a current that only flows in one direction in a wire or semiconductor, unlike AC which flows in both directions. DC is used in my Electronic circuits and other than that also found in many low voltage applications like batteries of solar power systems.

Electric vehicles mostly DC today in most of the systems, but in a lot of cases, it’s a variety between AC and DC for each use case.

E

EV – Electric Vehicle

An electric vehicle is a form of transport that uses electricity to power momentum. Electric vehicles uses electric motors which transfers electrical energy to mechanical energy.

EVSE – Electric Vehicle Supply Equipment

EVSE, is equipment used for charging your electric vehicle, or rather the battery inside. This term is often used instead or with charging stations, which provide this equipment.

F

FCEV – Fuel Cell Electric Vehicle

An FCEV is a type of electrical vehicle which uses oxygen and compressed hydrogen to produce energy which powers an electric motor.

Today many vehicles use this technology, ranging from typical cars to forklifts. This technology is also proposed to be used in trains and plains, because of the very high energy density and slim to no carbon footprint.

H

HEV – Hybrid Electric Vehicle

An HEV is a hybrid between a gasoline, i.e. typical car, and a electric car.
Hybrids often comes with it’s own separate battery pack and electric motor which can power the car just like a normal electric vehicle. But on top of that it’ll have a normal combustion engine as well, which either functions to supply the battery with power, or to run the whole car it self.

This is a very good option for many people. This is specially because a lot suffers from “range anxiety”. A gasoline car can easily be filled within a couple of minutes, where an EV typically takes hours to charge. On top of that many EV’s “only” has between 2 and 400 miles of range. A Hybrid Electric Vehicle is “the best of both worlds”, you can use your Electric Motor in the daily commute and switch to the gasoline if it runs low on longer trips.

I

Incentives

Incentives are cuts in the tax you are paying of your salary.
As an EV owner or a possible new EV owner, you must know that you can reap great benefits in tax reductions by buying/owning an EV. The specific amounts vary from state to state and country to country, so make sure to check up on this, on your local/national tax site.

ICE – Internal Combustion Engine

The old fashioned way to power your vehicle.

K

kWh – Kilowatt-Hour

The Kilowatt-Hour is a measure of energy used to measure how much energy goes into something. Often you’ll hear about the term when paying your bills for the electric utilities. When you charge your electric vehicle, your bill will also state how many kWh you are being billed for.

L

Lithium-Ion Battery

A lithium-ion battery is a rechargeable battery commonly used in electronic devices and electric vehicles. The lithium-ion battery was first prototyped in the 1970s by John Goodenough and later commercialized by Sony in 1991. In the lithium-ion battery, the lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge. This cycle reverses when recharging. Lithium-ion batteries are used today primarily because of their low cost, high energy density and low self-discharge.

Level 1 Charging

Level 1 charging refers to a standard household outlet. +120 VAC outlet, delivers power directly from the outlet in the wall to the EV’s on-board charger, charging time typically exceeds 20 hours depending on the capacity. The equipment is typically provided with your EV when buying.

Level 2 Charging

Level 2 charging refers to a charging station either wall-mounted at home or at a dedicated station placed near supermarkets or other parking spots. They typically deliver +240 VAC/VDC. Many Tesla owners get the Tesla Power Wall installed which is their form for level 2 charging. This will require Tesla themselves or another electrician to install correctly and safely. Time to fully charge is usually 8+ hours but not often over 12 hours depending on the capacity.

Level 3 Charging

Level 3 charging stations refer to fast-chargers and Tesla super-chargers. Not saying they are never found in homes, but this is not something you’ll get installed easily. You’ll find specially dedicated stations with dedicated fast or super-charging equipment. Level 3 charging is +400 VDC and some even go beyond 600 and 800 VDC. Charging time can be as low as 30 minutes on specially designed batteries.

P

PHEV – Plug-in Hybrid Electric Vehicle

A plug-in hybrid

R

Range

Range Anxiety

Regenerative Breaking

S

SAE-J1772

SAE COMBO (CCS)

T

Torque

Z

ZEV – Zero Emission Vehicle
