Hibar Systems Ltd was a Canadian manufacturer of automated, precision liquid dispensing and filling systems.. Hibar was started in 1974 when German-born Canadian engineer Heinz Barall developed a prototype of a precision metering pump that would dispense a small, precise amount (two microlitres) of electrolytes into button cell batteries.
Eveready Battery Company, Inc. is an American manufacturer of electric battery brands Eveready and Energizer, owned by Energizer Holdings. Its headquarters are located in St. Louis, Missouri. [1] The predecessor company began in 1890 in New York and was renamed in 1905.
The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input ...
Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.
Better Place was a venture-backed international company that developed and sold battery charging and battery switching services for electric cars.It was formally based in Palo Alto, California, but the bulk of its planning and operations were steered from Israel, where both its founder Shai Agassi and its chief investors resided.
The Grand Coulee Dam in the United States was expanded with a pump-back system in 1973. [75] Existing dams may be repowered with reversing turbines thereby extending the length of time the plant can operate at capacity. Optionally a pump back powerhouse such as the Russell Dam (1992) may be added to a dam for increased generating capacity ...
A Nio battery swap station at a carpark in Beijing. Battery swapping or battery switching is an electric vehicle technology that allows battery electric vehicles to quickly exchange a discharged battery pack for a fully charged one, rather than to recharge the vehicle via a charging station. Battery swapping is common in electric forklift ...
Zinc–air batteries have higher energy density than many other types of battery because atmospheric air is one of the battery reactants, in contrast to battery types that require a material such as manganese dioxide in combination with zinc. Energy density, when measured by weight (mass) is known as specific energy. The following table shows ...
