BMW ActiveE
The BMW ActiveE was a demonstration electric car based on the BMW 1 Series small family cars. It was the second vehicle after the Mini E to be developed under BMW Group’s Project i. The electric drive system was the latest addition to BMW’s EfficientDynamics programme. The US Environmental Protection Agency official range is , with an energy consumption of 33 kW·h/100 miles, and the agency rated the ActiveE's combined fuel economy at 2.3L/100 km (102 miles per gallon gasoline equivalent). The four-seater, rear-wheel drive ActiveE was unveiled at the North American International Auto Show in Detroit in January 2010. Deliveries of the ActiveE for field testing in the U.S. began in January 2012, after the Mini E trial ended. A total of 1,100 vehicles were planned to participate in the program worldwide, with 700 allocated for the U.S. trial and 35 to a trial in China. Participants in the Mini E trial had priority to lease the new electric car. Production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW 1 Series
The BMW 1 Series is a range of subcompact executive cars (C-segment) manufactured by BMW since 2004. It is the successor to the BMW 3 Series Compact and is currently in its third generation. Positioned as the entry level model in BMW range of products, the first generation was produced in hatchback, coupé and convertible body styles. Since 2014, the coupé and convertible models have been marketed separately as the 2 Series, therefore the 1 Series range no longer includes these body styles. A four-door sedan model became available for the Chinese market in 2017, using the front-wheel drive platform that is also used the basis for the third-generation 1 Series hatchback. A high-performance BMW M version called the BMW 1 Series M Coupé was produced for the first generation. Due to the 1 Series coupé model being replaced by the 2 Series, the 1 Series M Coupé was replaced by the BMW M2 in 2016. For the first two generations, the 1 Series uses a rear-wheel d ...

Miles Per Gallon Gasoline Equivalent
Miles per gallon gasoline equivalent (MPGe or MPGge) is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the energy consumption of conventional internal combustion vehicles rated in miles per U.S. gallon. The unit of energy consumed is deemed to be 33.7 kWh kilowatt-hours without regard to the efficiency of conversion of heat energy into electrical energy, also measured in kilowatt-hours (kWh). The equivalence of this unit to energy in a gallon of gasoline is true if and only if the heat engine, generating equipment, and power delivery to the car battery are 100% efficient. Actual heat engines differ vastly from this assumption. MPGe does not necessarily represent an equivalency in the operating costs between alternative fuel vehicles and the MPG rating of ...

Smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Management Of Electronic Devices And Systems
All electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. There are several techniques for cooling including various styles of heat sinks, thermoelectric coolers, forced air systems and fans, heat pipes, and others. In cases of extreme low environmental temperatures, it may actually be necessary to heat the electronic components to achieve satisfactory operation. Overview Thermal resistance of devices This is usually quoted as the thermal resistance from junction to case of the semiconductor device. The units are °C/W. For example, a heatsink rated at 10 °C/W will get 10 °C hotter than the surrounding air when it dissipates 1 Watt of heat. Thus, a heatsink with a low °C/W value is more efficient than a heatsink with a high °C/W value. Given two semiconductor device ...

Green Car Congress
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red was r ...

All-electric Range
All-electric range (AER) is the maximum driving range of an electric vehicle using only power from its on-board battery pack to traverse a given driving cycle. In the case of an all-electric vehicle, it means the maximum range per recharge. For a plug-in hybrid electric vehicle (PHEV), it means the maximum range in charge-depleting mode, as PHEVs can travel considerably further in charge-sustaining mode which utilizes both fuel combustion and the on-board battery pack. Calculating AER is made more complicated in PHEVs because of variations in drivetrain design. A vehicle like the Fisker Karma that uses a serial hybrid design has a clear AER. Similarly a vehicle like the Chevrolet Volt which disengages the internal combustion engine (ICE) from the drivetrain while in electric mode has a clear AER, however blend-mode PHEVs which use the ICE and electric motor in conjunction do not have a clear AER because they use both gasoline and electricity at the same time.
