EnergyBus
EnergyBus connectors are used for charging electric bicycles and pedelecs within Europe. The connector is circular in shape and specified for charging light electric vehicles at up to 1.5 kilowatts. Electric power is provided at 12–48 volts direct current (DC) so that any battery charger can charge any rechargeable battery. Data transmission between the battery and charger uses a CAN bus, exchanging CANopen messages defined by the CAN in Automation CiA-454 standard. Connector The EnergyBus physical interface consists of the plug and socket used to connect battery packs, battery chargers and other components. The connector used was designed by Rosenberger ( de) and contains six contacts: * 2 medium pins, for DC power transfer up to 1.5 kW at 12–48 volts DC, limited to 30 A. * 2 small pins, for CAN bus data bus high and low lines, transporting CANopen with CAN in Automation–454 messages. * 2 small pins, for auxiliary DC power to drive non-power components, ...

CAN Bus
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but it can also be used in many other contexts. For each device, the data in a frame is transmitted serially but in such a way that if more than one device transmits at the same time, the highest priority device can continue while the others back off. Frames are received by all devices, including by the transmitting device. History Development of the CAN bus started in 1983 at Robert Bosch GmbH. The protocol was officially released in 1986 at the Society of Automotive Engineers (SAE) conference in Detroit, Michigan. The first CAN controller chips were introduced by Intel in 1987, and shortly thereafter by Philips. Released in 1991, the Mercedes-Benz W140 was the first produc ...

Szombathely
Szombathely (; german: Steinamanger, ; see also other alternative names) is the 10th largest city in Hungary. It is the administrative centre of Vas county in the west of the country, located near the border with Austria. Szombathely lies by the streams ''Perint'' and ''Gyöngyös'' (literally "pearly"), where the Alpokalja (Lower Alps) mountains meet the Little Hungarian Plain. The oldest city in Hungary, it is known as the birthplace of Saint Martin of Tours. Etymology The name ''Szombathely'' is from Hungarian ''szombat'', "Saturday" and ''hely'', "place", referring to its status as a market town, and the medieval markets held on Saturday every week. Once a year during August they hold a carnival to remember the history of "Savaria". The Latin name ''Savaria'' or ''Sabaria'' comes from ''Sibaris'', the Latin name of the river ''Gyöngyös'' (German ''Güns''). The root of the word is the Proto-Indo-European word ''*seu'', meaning "wet". The Austrian overflowing of the Gyö ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Source
Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology, and open-source drug discovery. Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase ''open source'' became widely adopted, developers and producers have used a variety of other terms. ''Open source'' gained ...

Photovoltaic
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system man ...

Stand-alone Power System
A stand-alone power system (SAPS or SPS), also known as remote area power supply (RAPS), is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. Typical SAPS include one or more methods of electricity generation, energy storage, and regulation. Electricity is typically generated by one or more of the following methods: * Photovoltaic system using solar panels * Wind turbine * Geothermal source * Micro combined heat and power * Micro hydro * Diesel or biofuel generator * Thermoelectric generator (TEGs) Storage is typically implemented as a battery bank, but other solutions exist including fuel cells. Power drawn directly from the battery will be direct current extra-low voltage (DC ELV), and this is used especially for lighting as well as for DC appliances. An inverter is used to generate AC low voltage, which more typical appliances can be used with. Stand-alone photovoltaic power systems are independent of the utility ...

Islanding
Islanding is the condition in which a distributed generator (DG) continues to power a location even though external electrical grid power is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices. Additionally, without strict frequency control, the balance between load and generation in the islanded circuit can be violated, thereby leading to abnormal frequencies and voltages. For those reasons, distributed generators must detect islanding and immediately disconnect from the circuit; this is referred to as anti-islanding. Some designs, commonly known as a microgrid, allow for intentional islanding. In case of a power outage, a microgrid controller disconnects the local circuit from the grid on a dedicated switch and forces the distributed generator(s) to power the entire local load. A common example of intentional islanding is a distribution feeder that has sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide minimal input ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Off-the-shelf
Commercial off-the-shelf or commercially available off-the-shelf (COTS) products are packaged or canned (ready-made) hardware or software, which are adapted aftermarket to the needs of the purchasing organization, rather than the commissioning of custom-made, or bespoke, solutions. A related term, Mil-COTS, refers to COTS products for use by the U.S. military. In the context of the U.S. government, the Federal Acquisition Regulation (FAR) has defined "COTS" as a formal term for commercial items, including services, available in the commercial marketplace that can be bought and used under government contract. For example, Microsoft is a COTS software provider. Goods and construction materials may qualify as COTS but bulk cargo does not. Services associated with the commercial items may also qualify as COTS, including installation services, training services, and cloud services. COTS purchases are alternatives to custom software or one-off developments – government-funded dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
