Glossary

Type 1

A five pin plug that also features a clip, this connector is common in the US and is typically found on EVs manufactured by Asian and US brands (e.g. Nissan, Mitsubishi and GM/Vauxhall/Opel). However its prominence is fading as Nissan have moved to Type 2.

Type 2

A seven pin plug with one flat edge, this connector was originally favoured by European brands e.g. BMW, VW group, but is now becoming the most popular on all cars. Can carry three-phase power and locks into the socket of a charging point.

prewiew
UK 3 pin

The plug for a standard UK electrical outlet. This connector can be used to charge some EVs in an emergency but lacks the safety, speed and security features of a dedicated charge point.

Ultra-Low Emission Vehicle (ULEV)

A car that has official tailpipe carbon dioxide emissions of less than 75g/km, and is therefore eligible for grants and benefits from the UK government. 

prewiew
Urban Mobility

Mobility in cities and urban areas can be divided into freight transportation and the mobility of passengers – both via public and individualized transport. It will become a cornerstone for the further development of urban areas.

prewiew
Vehicle to Grid (V2G)

The concept of using your electric car battery to release power back through the charger either for use in the local building or back into the grid at large during time of high grid demand. 

prewiew
VRLA battery (valve-regulated lead-acid battery)

A rechargeable lead-acid battery.

Worldwide harmonized Light vehicles Test Procedure (WLTP)

WLTP is the more thorough emissions and efficiency testing regime that has broadly superseded the NEDC. The test provides a less optimistic verdict on real world electric range, but it is arguably still more optimistic than a vehicle’s actual real world range.

Zero Emissions

The phrase ‘zero emissions’ is mentioned quite often when e-mobility is discussed. In most cases it is used to identify a vehicle which does not output any harmful pollutants at the point of use.

prewiew
Zero Emissions Commitment

The Zero Emissions Commitment is the climate change commitment that would result from setting anthropogenic emissions to zero. It is determined by both inertia in physical climate system components (ocean, cryosphere, land surface) and carbon cycle inertia.
