Capabus
A capacitor electric vehicle is a vehicle that uses supercapacitors (also called ultracapacitors) to store electricity. , the best ultracapacitors can only store about 5% of the energy that lithium-ion rechargeable batteries can, limiting them to a couple of miles per charge. This makes them ineffective as a general energy storage medium for passenger vehicles. But ultracapacitors can charge much faster than Battery (electricity), batteries, so in vehicles such as buses that have to stop frequently at known points where charging facilities can be provided, energy storage based exclusively on ultracapacitors becomes viable. Capabus China is experimenting with a new form of electric bus, known as ''Capabus'', which runs without continuous overhead lines (is an autonomous vehicle) by using power stored in large onboard electric double-layer capacitors (EDLCs), which are quickly recharged whenever the vehicle stops at any bus stop (under so-called electric umbrellas), and fully c ...

Electric Double-layer Capacitor
alt=Supercapacitor, upright=1.5, Schematic illustration of a supercapacitor upright=1.5, A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries. Unlike ordinary capacitors, supercapacitors do not use the conventional solid dielectric, but rather, they use electrostatic double-layer capacitance and electrochemical pseudocapacitance, both of which contribute to the total energy storage of the capacitor. Supercapacitors are used in applica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Activated Carbon
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area available for ''adsorption '' or chemical reactions. (Adsorption, not to be confused with Absorption (chemistry), absorption, is a process where atoms or molecules adhere to a surface). The pores can be thought of as a microscopic "sponge" structure. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. ''Activated'' is sometimes replaced by ''active''. Because it is so porous on a microscopic scale, one gram of activated carbon has a surface area of over , as determined by gas absorption and its porosity can run 10ML/day in terms of treated water per gram. Researchers at Cornell University synthesized an ultrahigh surface area activated ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Density
In physics, energy density is the quotient between the amount of energy stored in a given system or contained in a given region of space and the volume of the system or region considered. Often only the ''useful'' or extractable energy is measured. It is sometimes confused with stored energy per unit mass, which is called ''specific energy'' or . There are different types of energy stored, corresponding to a particular type of reaction. In order of the typical magnitude of the energy stored, examples of reactions are: Nuclear power, nuclear, Chemical energy, chemical (including Electrochemistry, electrochemical), electrical, pressure, Deformation (engineering), material deformation or in Electromagnetic field, electromagnetic fields. Nuclear reactions take place in stars and nuclear power plants, both of which derive energy from the binding energy of nuclei. Chemical reactions are used by organisms to derive energy from food and by automobiles from the combustion of gasoline. Liqu ...

Plug-in Hybrid
A plug-in hybrid electric vehicle (PHEV) or simply plug-in hybrid is a type of hybrid electric vehicle equipped with a rechargeable battery pack that can be directly replenished via a charging cable plugged into an external electric power source, in addition to charging internally by its on-board internal combustion engine-powered generator. While PHEVs are predominantly passenger cars, there are also plug-in hybrid variants of sports cars, commercial vehicles, vans, utility trucks, buses, trains, motorcycles, mopeds, military vehicles and boats. Similar to battery electric vehicles (BEVs), plug-in hybrids can use centralized generators of renewable energy (e.g. solar, wind or hydroelectric) to be largely emission-free, or a fossil plant in which case they displace greenhouse gas emissions from the car tailpipe exhaust to the power station. As opposed to conventional hybrid electric vehicles (HEVs), PHEVs generally have a larger battery pack that can be recharged (the ...

Régie Autonome Des Transports Parisiens
The RATP Group () is a French state-owned enterprise (EPIC) that operates public transport systems primarily in Paris, France. Headquartered in Paris, it originally operated under the name (). Its logo represents the Seine's meandering path through the Paris Region stylised as the face of a person looking up. The company had described itself as the fourth-largest presence in public transport. RATP Group was established in 1949 with the express purpose of operating Paris's public transport system. During the twentieth century, it focused solely on the provision of the capital's various forms of transit, from the Paris Métro, Île-de-France tram, and the RATP bus network, as well as part of the regional express rail (RER) network. However, since 2002, RATP Group's operations have no longer been geographically restricted; it has competitively pursued contracts to operate transit systems around the world. It also had a partnership with, and a minority shareholding in, Transdev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg- Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze-out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hütte ...

Charging Station
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment (EVSE), is a power supply electrical device, device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrid vehicles). There are two main types of EV chargers: Alternating current (AC) charging stations and direct current (DC) charging stations. Electric vehicle batteries can only be charged by direct current electricity, while most mains electricity is delivered from the power grid as alternating current. For this reason, most electric vehicles have a built-in AC-to-DC converter commonly known as the "onboard charger" (OBC). At an AC charging station, AC power from the grid is supplied to this onboard charger, which converts it into DC power to recharge the battery. DC chargers provide higher power charging (which requires much larger AC-to- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
