Leipzig
Leipzig ( , ; Upper Saxon: ) is the most populous city in the German state of Saxony. Leipzig's population of 605,407 inhabitants (1.1 million in the larger urban zone) as of 2021 places the city as Germany's eighth most populous, as well as the second most populous city in the area of the former East Germany after (East) Berlin. Together with Halle (Saale), the city forms the polycentric Leipzig-Halle Conurbation. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport. Leipzig is located about southwest of Berlin, in the southernmost part of the North German Plain (known as Leipzig Bay), at the confluence of the White Elster River (progression: ) and two of its tributaries: the Pleiße and the Parthe. The name of the city and those of many of its boroughs are of Slavic origin. Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval trad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Range Extender
A 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). Many range extender vehicles, including the Chevrolet Volt and the BMW i3, are able to charge their batteries from the grid as well as from the range extender, and therefore are a type of plug-in hybrid electric vehicle (PHEV). Motivation The key function of the range extender is to increase the vehicle's range. Range autonomy is one of the main barriers for the commercial success of electric vehi ...

Concept Car
A concept car (also known as a concept vehicle, show vehicle or prototype) is a car made to showcase new styling and/or new technology. They are often exhibited at motor shows to gauge customer reaction to new and radical designs which may or may not be mass-produced. General Motors designer Harley Earl is generally credited with inventing the concept car, and did much to popularize it through its traveling Motorama shows of the 1950s. Concept cars never go into production directly. In modern times all would have to undergo many changes before the design is finalized for the sake of practicality, safety, regulatory compliance, and cost. A " production-intent" prototype, as opposed to a concept vehicle, serves this purpose. Design Concept cars are often radical in engine or design. Some use non-traditional, exotic, or expensive materials, ranging from paper to carbon fiber to refined alloys. Others have unique layouts, such as gullwing doors, 3 or 5 (or more) wheels, or spe ...

Suicide Door
A suicide door is an automobile door hinged at its rear rather than the front. Such doors were originally used on horse-drawn carriages, but are rarely found on modern vehicles, primarily because they are perceived as being less safe than a front-hinged door. Being rear-hinged, if the vehicle was moving and the door opened, the driver/passenger would have to lean forward and out of the vehicle to close it. As seat belts were not in common use at that time, the risk of falling out of the car and into traffic was high, hence the name "suicide door". Initially standard on many models, later they became popularized in the custom car trade. Automobile manufacturers call the doors coach doors (Rolls-Royce and Lincoln), flexdoors (Opel), freestyle doors (Mazda), rear access doors (Saturn), or simply describe them as rear-hinged doors. History Rear-hinged doors were common on cars manufactured in the first half of the 20th century, including the iconic Citroën Traction Avant. In the ...

Carbon Fibre Reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (English in the Commonwealth of Nations, Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermosetting polymer, thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester resin, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW I
The BMW i is a sub-brand of BMW founded in 2011 to design and manufacture plug-in electric vehicles. The company initially released two vehicles: the i3 all-electric car and the i8 plug-in hybrid. The all-electric iX3 SUV was released in late 2020, while iX SUV and the i4 all-electric liftback sedan followed later in 2021. Concept versions of both the i3 and i8 were shown at the 2009 Frankfurt Motor Show. Series production of the BMW i3 for retail customers began in September 2013, and the European market launch took place in November 2013, with the first retail deliveries in Germany. The BMW i8 was launched in Germany in June 2014. The United States, Norway, Germany, and the UK are the main markets for both models. In February 2016, BMW announced the introduction of the "iPerformance" model designation, which is being given to all BMW plug-in hybrid vehicles from July 2016. The aim is to provide a visible indicator of the transfer of technology from BMW i to the BM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zero-emissions Vehicle
A zero-emission vehicle, or ZEV, is a vehicle that does not emit exhaust gas or other pollutants from the onboard source of power. The California definition also adds that this includes under any and all possible operational modes and conditions. This is because under cold-start conditions for example, internal combustion engines tend to produce the maximum amount of pollutants. In a number of countries and states, transport is cited as the main source of greenhouse gases (GHG) and other pollutants. The desire to reduce this is thus politically strong. Terminology Harmful pollutants to the health and the environment include particulates (soot), hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen. Although not considered emission pollutants by the original California Air Resources Board (CARB) or U.S. Environmental Protection Agency (EPA) definitions, the most recent common use of the term also includes volatile organic compounds, several air toxics (most no ...

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
