Glossary of Terms
A type of charging method. AC plugs and sockets allow devices to be connected to the primary power supply of a building.
Behind the Meter
Renewable Energy system uniquely designed and built for a single building or facility, reducing the carbon footprint of the building by generating electricity locally using renewable sources.
A type of electric vehicle (EV) that uses chemical energy stored in rechargeable battery packs. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion.
A type of DC connector, trade name of a quick charging method for battery electric vehicles delivering up to 62.5 kW by 500 V, 125 A direct current via a special electrical connector.
A type of charging method. As an electrical connector for supplying direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. Battery storage requires the charge to be delivered through this method. CHAdeMO, CCS and Tesla Type 2 are all DC connectors.
Demand Side Response (DSR)
Energy demand management, also known as demand-side management (DSM) or demand-side response (DSR), is the modification of consumer demand for energy through various methods such as financial incentives and behavioural change through education.
Distributed energy resources (DERs)
Electricity-producing resources or controllable loads that are directly connected to a local distribution system or connected to a host facility within the local distribution system.
Distribution Network Operator (DNO)
Company licensed to distribute electricity in the UK.
The time which an EV is plugged into a charging point.
Electric Vehicle Supply Equipment commonly called a charging station or charging dock. These charging stations are built into the EV charging standard for electrical safety; first for the user, then the vehicle and then the power grid. The charging station’s primary function is as electrical safety equipment.
Technical specification which defines the parameters a facility connected to a public electric network has to meet to ensure safe, secure and economic proper functioning of the electric system.
Hybrid Electric Vehicle
A type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system.
Internal Combustion Vehicles
A vehicle which generates motive power by the burning of petrol, oil, or other fuel with air inside the engine.
Also known as demand sidemanagement (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output.
Office for Low Emission Vehicles (OLVE)
Team working across government to support the early market for ultra-low emission vehicles (ULEV).
Technique used to shift a portion of an electrical load at a peak time of day to a non-peak time.
Plug-in hybrid electric vehicle (PHEV)
Hybrid electric vehicle whose battery can be recharged by plugging it in to an external source of electric power as well by its on-board engine and generator.
Concept of modernizing the Electric grid.
Solar Photovoltaic (PV) is a technology that converts sunlight (solar radiation) into direct current electricity by using semiconductors. When the sun hits the semiconductor within the PV cell, electrons are freed and form an electric current. Solar PV technology is generally employed on a panel (hence solar panels).
Transmission System Operator (TSO)
Entity entrusted with transporting energy in the form of natural gas or electrical power on a national or regional level, using fixed infrastructure.
The process of making an energy production and delivery system more efficient by encouraging additional energy use during periods of lowest system demand.
Virtual Power Plant
Cloud-based distributed power plant that aggregates the capacities of heterogeneous Distributed Energy Resources (DERs).
