Glossary of Terms

BEV - Battery Electric Vehicle
EV - Electric Vehicle
PHEV - Plug-in Hybrid Electric Vehicle

 

Note: Not all PHEV are Capable of DC Rapid Charging.

Check the Technical Specifications carefully if this is a requirement for you. 

Better still - go and look at the actual Charge port of the Vehicle so you know

for sure if the High Power DC Socket is present or not.


Hybrid - A Mix of Petrol / Diesel / Hydrogen / Battery and Electric Motor(s)

HEV - Hybrid Electric Vehicle 

SHS- Super Hybrid System  

MHEV - Mild Hybrid Electric Vehicle 

EREV - Extended Range Electric Vehicle

NEV - What does it mean?

Rapid Charging 50kW-149kW

Ultra-Rapid Charging 150kW - 999kW
 
CCS2 - Combined Charging System 2
CHAdeMO -  'Charge for Moving'
'CHAdeMO is an abbreviation for "CHArge de MOve" #
MCS - MegaWatt Charging System 
 
CPO- Charge Point Operator
 
PAYG Pay As You Go
p/kWh Pence Per kiloWatt Hour - How much in Pence 1 kWh of Electrical Energy will cost in the United Kingdom 
kiloWatt Hour - A unit of Energy Storage used to describe how much Elecrical Charge a Battery Can hold / accept. 
kiloWatt (kW) - A unit of Power used to describe for example a 350 kW Charger 
Overstay Fees  - A Penalty £ You pay if you stay Longer than permitted at Charge Point.

There is often a time limit when Charging, which may be 90 Mins or sometimes 30 Mins. Always Read the Signage to Avoid these fees.

(AC) Alternating Current  - Best for When your EV is Stationary - At Home during the day, overnight or at Work or a Long Stay Car Park such as a Station or Holiday Site  / Overnight stay Destination.

(DC) Direct Current - For when you're on the Move!  Ultra-Rapid Charging can get you back on the Road in around 31-35 Minutes* . * Average dwell times 2024

EVSE Electric Vehicle Supply Equipment 

Home Charger EVSE Output 7.4kW Nominal at 1 Phase

Public AC Charger EVSE Output 3kW /7kW/11KW /22kW 

Public Rapid DC Charger EVSE Output 50-149kW

Public Ultra-Rapid Charger EVSE Output Range 150-999kW

Megawatt Charging System EVSE Output 1MW-4MW  (MW - Mega Watt)

 

Uni-directional (ONE WAY)

Bi-Directional Charging (2 WAY - Charge and Discharge)

V2L Vehicle to Load 

V2G Vehicle to Grid 

V2X Vehicle to Anything

Autocharge - Seemless Authentication for your EV Via its MAC Address or VIN

Plug & Charge - ​Plug & Charge uses the ISO 15118 protocol specifications, digital signatures, and public key infrastructures to secure communications between the vehicle and the charging infrastructure. While this approach offers more stringent security, it is far more complex, costly, and time consuming to implement. It also requires vehicle and charger manufacturers to support ISO 15118.

ABC Always Be Charging

Re-Gen - Regenerative Braking using the Electric Motor(s)

'Rapid-Gating'  Charging Power  / Rate is Limited to due Battery Protection at Higher Temperatures / Repeated Rapid Charging Events

'Cold-Gating' Slow Charging Rates encountered when the Battery Temperature is insufficient 

to obtain Optimum Charging. 

Preheating - heating the Battery towards it's optimum temperature for Charging

Pre-Conditioning heating or Cooling the Battery in order to obtain the optimum temperature prior to Charging.

*notes:

The EU designated the Type 2 connector as the standard for AC charging in 2013 (Directive 2014/94/EU), requiring public chargepoints to support it. This led manufacturers to equip nearly all new electric cars sold in the UK and Europe with Type 2 inlets from around 2014 onward. By the mid-2010s, Type 1 was phased out for new models (e.g., newer Nissan Leaf from 2018), making Type 2 the effective standard for all new UK EVs since then. No later year enforced full compliance retroactively.

CCS2 (Combined Charging System Type 2) gained popularity and became the dominant DC fast-charging standard in the UK from 2018 onward, phasing out CHAdeMO. EU Directive 2014/94/EU supported this shift, with high-power DC points requiring CCS2 compatibility after 2017. Most new UK EVs adopted CCS2 by the late 2010s (e.g., Tesla Model 3 in 2019).
