Range extenderA range extender is a fuel-based auxiliary power unit (APU) that extends the range of a battery electric vehicle by driving an electric generator that charges the vehicle's battery. This arrangement is known as a series hybrid drivetrain. The most commonly used range extenders are internal combustion engines, but fuel-cells or other engine types can be used. Range extender vehicles are also referred to as extended-range electric vehicles (EREV), range-extended electric vehicles (REEV), and range-extended battery-electric vehicle (BEVx) by the California Air Resources Board (CARB).
Lithium iron phosphateLithium iron phosphate or lithium ferro-phosphate (LFP) is an inorganic compound with the formula LiFePO4. It is a gray, red-grey, brown or black solid that is insoluble in water. The material has attracted attention as a component of lithium iron phosphate batteries, a type of Li-ion battery. This battery chemistry is targeted for use in power tools, electric vehicles, solar energy installations and more recently large grid-scale energy storage.
Battery swappingBattery 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 new one, as an alternative to recharging the vehicle via a charging station. Battery swapping is common in electric forklift applications. Currently, Taiwanese electric scooter manufacturer Gogoro operates the largest battery swap network for electric mopeds, with nearly 11,000 GoStations in Taiwan, and 250 in Mainland China.
FiatFiat Automobiles S.p.A. (UKˈfiːət,_-æt , US-ɑːt , ˈfiːat; originally FIAT, Fabbrica Italiana Automobili di Torino) is an Italian automobile manufacturer, formerly part of Fiat Chrysler Automobiles, and since 2021 a subsidiary of Stellantis through its Italian division Stellantis Italy. Fiat Automobiles was formed in January 2007 when Fiat S.p.A. reorganized its automobile business, and traces its history back to 1899, when the first Fiat automobile, the Fiat 4 HP, was produced.
WheelchairA wheelchair is a chair with wheels, used when walking is difficult or impossible due to illness, injury, problems related to old age, or disability. Wheelchairs come in a wide variety of formats to meet and offer different larger demands than the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as they seen with sports wheelchairs and beach wheelchairs.
Power densityPower density is the amount of power (time rate of energy transfer) per unit volume. In energy transformers including batteries, fuel cells, motors, power supply units etc., power density refers to a volume, where it is often called volume power density, expressed as W/m3. In reciprocating internal combustion engines, power density (power per swept volume or brake horsepower per cubic centimeter) is an important metric, based on the internal capacity of the engine, not its external size.
Active mobilityActive mobility, soft mobility, active travel, active transport or active transportation is the transport of people or goods, through non-motorized means, based around human physical activity. The best-known forms of active mobility are walking and cycling, though other modes include running, rowing, skateboarding, kick scooters and roller skates. Due to its prevalence, cycling is sometimes considered separately from the other forms of active mobility.
Lithium–air batteryThe lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy. Indeed, the theoretical specific energy of a non-aqueous Li–air battery, in the charged state with Li2O2 product and excluding the oxygen mass, is ~40.1 MJ/kg = 11.14 kWh/kg of lithium.
Milk floatA milk float is a vehicle specifically designed for the delivery of fresh milk. Today, milk floats are usually battery electric vehicles (BEV), but they were formerly horse-drawn floats. They were once common in many European countries, particularly the United Kingdom, and were operated by local dairies. However, in recent years, as the number of supermarkets, small independent grocers and petrol stations, and convenience stores stocking fresh milk has increased, many people have switched from regular home delivery to obtaining fresh milk from these other sources.
CleanTechnicaCleanTechnica is a US-based website dedicated to aggregating news in clean technology, sustainable energy, and electric vehicles, with a focus on Tesla. CleanTechnica publishes stories on a wide range of topics that are cited by mainstream media such as Business Insider (on Lindsey Graham), Reuters (on nanotech for energy storage), ThinkProgress (on wind power in Texas), The Washington Post (on suburban living), Forbes (on the Byton M-Byte) and Slate (on mask stockpiling during the COVID-19 pandemic).
