CHAdeMO is a DC charging standard for electric vehicles. It enables seamless communication between the car and the charger and is an abbreviation of “CHArge de MOve,” equivalent to “charge for moving,” and is a pun for “O cha demo ikaga desuka.” in Japanese, meaning “Let's have a cup of tea while charging.”

A charging station, also called electric vehicle charging station, electric recharging point, charging point, charge point, electronic charging station (ECS), and electric vehicle supply equipment (EVSE), is a machine that supplies electric energy to charge plug-in electric vehicles.

Putting scrap or other iron raw material in the electric arc furnace for melting into steel.

Combined heat and power is a way to make even more efficient use of fuel cells. The waste heat from the electricity production is used to heat water or for space heating.

Cobalt is the chemical element of atomic number 27, a hard silvery-white magnetic metal. Some Cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more normally produced as a by-product of copper and nickel mining. The Copperbelt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production. Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys.

A cogging mill is a heavy duty rolling mill that is used for shaping reheated steel ingots into blooms or slabs. The mill allows the ingot to pass and re-pass through the rolling stand until the profile that is desired is achieved.

Coke is a processed form of coal and is the basic fuel consumed in blast furnaces during the smelting of iron. Coke, iron ore and limestone are the principal inputs for blast furnace ironmaking. Coke provides thermal energy, combines with the oxygen in the ore to release iron, and ensures a permeable physical structure within the furnace to allow hot gases to move upwards, heating the incoming materials, causing the molten iron and slag to move downwards for tapping.

A coke oven battery is a set of ovens that process coal into coke. They are constructed in batteries of ten to 100 ovens that are 20 feet tall, 40 feet long, and less than two feet wide. Coke batteries are usually the dirtiest area in a steel mill complex as they are affected by the exhaust fumes emitted when coke is pushed from the ovens.

Coking coal contains certain properties that suit it to iron making, unlike the thermal or steaming coal that is used in power stations/industrial or domestic heating. Also unlike steaming coal, when heated in the absence of air, coking coal forms a hard and sponge-like material which is called coke. 

Cold finishing is the process of steel either with surface removal (polishing, grinding, peeling) or without surface removal (e.g. through wire drawing), primarily for further machining into shapes such as gears, shafts, hydraulic fittings etc

The term 'cold rolled coil' is given to the process of flat rolled steel that has been rolled on a cold strip mill to reduce thickness and improve flatness. This form of gauge reduction can also be referred to as cold reduction.

Cold rolled strip is a sheet steel that has been pickled and run through a cold-reduction mill. It differs from hot-rolled sheet because it is considerably thinner and stronger, allowing it to be sold for a premium.

Cold working is where the structure and shape of steel is changed through rolling, hammering or stretching at low or room temperatures. This process is done to create a permanent increase in the hardness and strength of the steel.

Colour coated or prepainted steel, or prepaint, is used to describe steel coil that has been coated in paint, powder or film while being applied in a continuous process prior to it being cut and shaped. It provides a durable uniform surface finish, and can be an alternative to conventional post-manufacture painting of steel parts. 

Commercial energy storage (CES) or battery storage systems are battery units that are installed to offer businesses a way to store and discharge electricity at specific times, operate independently from the grid and offer backup power when needed.
