[sta_anchor id="ICEing"]ICEing
A term used when an ICE vehicle parks in or blocks an Electric Vehicle charging point.

[sta_anchor id="IEC_62196"]IEC 62196
An Electric Vehicle charging standard which includes charging modes and connection configurations (Type 2/Mennekes), and requirements for specific implementations (including safety requirements) of both electric vehicle (EV)and electric vehicle supply equipment (EVSE) in a charging system. It specifies mechanisms such that, first, power is not supplied unless a vehicle is connected and, second, the vehicle is immobilised while still connected, for example.

[sta_anchor id="J1772"]J1772
A charging standard of plugs and sockets preferred by Japanese manufactures and found on cars such as the Nissan Leaf or Mitsubishi Outlander. Also called Type 1 and is single phase only.

[sta_anchor id="kW"]kW
Kilowatt. The Watt is named for Scottish scientist James Watt and is a measurement of power. 1000 Watts = 1 Kilowatt.

[sta_anchor id="kWh"]kWh
Kilowatt Hour. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt-hours is the power in kilowatts multiplied by the time in hours. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

[sta_anchor id="Li-Ion"]Li-Ion
Lithium Ion. A type of battery found in many electronic devices such as mobile phones and commonly used in modern Electric Vehicles.

[sta_anchor id="Manx_Utilities"]Manx Utilities
The Manx Utilities Authority or MUA is a Statutory Board of the Isle of Man Government created in April 2014 following the merger of the Isle of Man Water and Sewerage Authority and the Manx Electricity Authority. They are the sole electricity supplier on the Isle of Man.

[sta_anchor id="Mennekes"]Mennekes
The Mennekes connector, also known as Type 2 or IEC 62196, is a common charging connector used on many European Electric Vehicles and also Tesla's in Europe. The connector allows for single or three-phase power.

[sta_anchor id="Mode_1"]Mode 1
