Battery Electric Bus
A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source. Battery electric buses offer the potential for zero-emissions, in addition to much quieter operation and better acceleration compared to traditional buses. They also eliminate infrastructure needed for a constant grid connection and allow routes to be modified without infrastructure changes, in contrast with a trolleybus. They typically recover braking energy to increase efficiency by a regenerative brake. With energy consumption of about , the cost of ownership is lower than diesel buses.Fraunhofer-Institut für Verkehrs- und Infrastruktursysteme Praxistest mit einem Fahrzeug zwischen 03.11.2014 b ...

Bus Stop
A bus stop is a place where Public transport bus service, buses stop for passengers to get on and off the bus. The construction of bus stops tends to reflect the level of usage, where stops at busy locations may have shelter (building), shelters, seating, and possibly Passenger information system, electronic passenger information systems; less busy stops may use a simple pole and flag to mark the location. Bus stops are, in some locations, clustered together into transport hubs allowing interchange between routes from nearby stops and with other public transport modes to maximise convenience. Types of service For operational purposes, there are three main kinds of stops: Scheduled stops, at which the bus should stop irrespective of demand; Request stop#Bus transport, request stops (or flag stop), at which the vehicle will stop only on request; and hail and ride stops, at which a vehicle will stop anywhere along the designated section of road on request. Certain stops may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the Rail profile, rails. Other types of current collectors include the bow collector and the trolley pole. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "current collector, shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad. The familiar diamond-shaped roller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 15118
ISO 15118 ''Road vehicles -- Vehicle to grid communication interface'' is a proposed international standard defining a vehicle to grid (V2G) communication interface for bi-directional charging/discharging of electric vehicles. The standard provides multiple use cases like secure communication, smart charging and the Plug & Charge feature used by some electric vehicle networks. Overview ISO 15118 is one of the International Electrotechnical Commission's (IEC) group of standards for electric road vehicles and electric industrial trucks, and is the responsibility of Joint Working Group 1 (JWG1 V2G) of IEC Technical Committee 69 (TC69) together with subcommittee 31 (SC31) of the International Organization for Standardization's (ISO) Technical Committee 22 (TC22) on road vehicles. ISO and IEC began working together on the standard in 2010, and a Plug & Charge section was released in 2014. No automakers had a productive implementation of the standard by 2018. V2G-PKI ISO 15118 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Of Automotive Engineers
SAE International is a global professional association and standards organization based in Warrendale, Pennsylvania, United States. Formerly the Society of Automotive Engineers, the organization adopted its current name in 2006 to reflect both its international membership and the increased scope of its activities beyond automotive engineering and the automotive industry to include aerospace and other transport industries, as well as commercial vehicles including autonomous vehicles such as self-driving cars, trucks, surface vessels, drones, and related technologies. SAE International has over 138,000 global members. Membership is granted to individuals, rather than companies. Aside from its standardization efforts, SAE International also devotes resources to projects and programs in STEM education, professional certification, and collegiate design competitions. History In the early 1900s there were dozens of automobile manufacturers in the United States, and many more w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercapacitor
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] |

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] |
SAE J3105
SAE J3105 is a recommended practice for automated connection devices (ACD) that mate chargers with battery electric buses and heavy-duty vehicles. The practice is maintained by the SAE International with the formal title "Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices Recommended Practice", and was first issued in January 2020. It covers the general physical, electrical, functional, testing, and performance requirements for automated conductive DC power transfer systems intended for heavy duty vehicles, focusing primarily on transit buses. J3105 defines a common automated conductive charging system architecture so that any vehicle selecting one of the supplemental specific ACD implementations can use any charger that complies with that specific implementation, regardless of manufacturer, similar to how the earlier IEC 62196, SAE J1772, and SAE J3068 standards define the characteristics for a manually-plugged electric vehicle supply equipment in ...

Electric Bus (2022)
An electric bus is a bus that is propelled using electric motors, as opposed to a conventional internal combustion engine. Electric buses can store the needed electrical energy on board, or be fed mains electricity continuously from an external source such as overhead lines. The majority of buses using on-board energy storage are battery electric buses (which is what this article mostly deals with), where the electric motor obtains energy from an onboard battery pack, although examples of other storage modes do exist, such as the gyrobus that uses flywheel energy storage. When electricity is not stored on board, it is supplied by contact with outside power supplies, for example, via a current collector (like the overhead conduction poles in trolleybuses), or with a ground-level power supply, or through inductive charging. As of 2017, 99% of all battery electric buses in the world have been deployed in Mainland China, with more than 421,000 buses on the road, which is 17% of C ...
