EV Terms and Definitions

Get Yourself EVucated

In some ways owning an EV requires learning a whole new lingo. As it involves tech and in such a new industry it’s bound to continue creating a language of its own. The terms defined here will get you started with the basics and you can be sure we’ll be tackling EV acronyms next.

Battery Management System

Manages/protects the battery by monitoring the rate of charge, balancing and temperature of each cell.

Charge Coupler

The male and female receptacles that connect the EV to a charger.

Charging Station, Charging Point or Charge Point

Any location where an EV can be charged.

Combined Charging System

A method of quickly charging EVs using a specialized electric connection which combines the inlets for AC and DC using shared communications pins.

E Route

Routes built specifically for EV traffic, utilizing the most accessible charging stations. Very new in concept and only a few currently exist.

Ebike or E-bike

Any electric powered bicycle, cycle or scooter.

En-route Charging

Essentially charging as you go. This method requires high-powered Level 3 chargers to be at all effective and is more often used for trips over longer distances.

Etaxi or E-taxi

Any electric powered taxi or rickshaw.

Fast Charging

Another name for Level 2 AC charging (using a 240V outlet) and can charge up to 15% faster than Level 1 trickle charging (roughly 3-4 hours).

Home Charging

Simply means charging your EV at home, generally using a dedicated Level 1 or Level 2 charging point.


A car which integrates a small battery with an electric motor to enhance the efficiency of an internal combustion engine. The electric motor is not used for propulsion and cannot be charged by external means.


When an vehicle with an internal combustion engine (ICE) is parked at a chargepoint, rendering it useless.


What you call someone with an internal combustion engine (ICE) vehicle who parks in a space reserved for EVs.

ICE Machine

A term directed at internal combustion engine (ICE) vehicles.

Level 1 Charging

Also called Trickle Charging and provides alternating current (AC) energy to the vehicle’s onboard charger. Uses a standard 120V outlet and will fully charge an EV in +/-18 hours.

Level 2 Charging

Also called Fast Charging and provides alternating current (AC) energy to the vehicle’s onboard charger. Uses a standard 240V outlet (often used for large home appliances) and will fully charge an EV much faster than Level 1 (closer to 2-3 hours).

Level 3 Charging

Also called Rapid Charging and provides direct current (DC) energy directly to the vehicle’s battery (bypassing the onboard charger). Level 3 chargers can only be found in public or corridor chargers and charge using a min 24kW and a max of 160kW. Can charge an EV to roughly 80% capacity in half an hour.

Lithium-Ion Battery

A rechargeable battery commonly used to power everything from smartphones to EVs.

Off Peak Charging

Charging during off-peak hours when the cost and demand for energy is at its lowest.

Range Anxiety

Stress caused by anxiety over running your EV out of power before reaching a destination.

The Rapid Charge Paradox

The ironic realization that EV drivers often have to wait in line to use rapid (Level 3) chargers. Thus rendering them… less rapid.

Rapid Charging

Another name for Level 3 DC charging, which is only found in public or corridor chargers and is especially useful for long-distance travel. In half an hour it can charge an EV to roughly 80% capacity.

Reduction Gear

Similar to a transmission for EVs, reduction gears reduce the high rotational speed of an electric engine and converts it allowing the vehicle to slow when you lift off the accelerator.

Regenerative Braking

An energy recovery mechanism which uses kinetic energy from application of the breaks to recharge the battery.

Slow Charging

A home charging option that is faster than trickle charging. This requires dedicated (smart) hardware to convert a standard outlet. Technically this is also considered Level 1 AC charging, which uses a 120V outlet.

Smart Charging

A broad term encompassing the wifi functions performed at a connected charge point.

Top up Charging

The practice of charging your EV whenever given the opportunity of a convenient charge spot.

Trickle Charging

Another name for Level 1 AC charging (using a 120V outlet) which can take up to 18 hours to fully charge an EV.
