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
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.

PM Particulate Matter
NOx Nitrous Oxides
CO2 Carbon Dioxide
(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).
