San Dimas, California
San Dimas ( Spanish for "Saint Dismas") is a city in the San Gabriel Valley of Los Angeles County, California, United States. At the 2020 census, its population was 34,924. It historically took its name from San Dimas Canyon in the San Gabriel Mountains above the northern section of present-day San Dimas. San Dimas is bordered by the San Gabriel Mountains range to the north, Glendora and Covina to the west, La Verne to its north and east side, Pomona to its south and east side, Walnut and the unincorporated community of Ramona to the southwest, and the unincorporated community of West San Dimas, which is an enclave in the southwestern portion of the city. History The first known European exploration of the area was in 1774, when Juan Bautista de Anza passed through on the first overland expedition of Las Californias, from New Spain-Mexico towards Monterey Bay. The area was originally developed in 1837 with the Mexican land grant from Governor Juan Bautista Alvarado t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium Polymer Batteries
A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid ( gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, such as mobile devices, radio-controlled aircraft and some electric vehicles. History LiPo cells follow the history of lithium-ion and lithium-metal cells which underwent extensive research during the 1980s, reaching a significant milestone with Sony's first commercial cylindrical Li-ion cell in 1991. After that, other packaging forms evolved, including the flat pouch format. Design origin and terminology Lithium polymer cells have evolved from lithium-ion and lithium-metal batteries. The primary difference is that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inverter (electrical)
A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process. Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and vo ...

Powertrain
A drivetrain (also frequently spelled as drive train or sometimes drive-train) is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components. In contrast, the powertrain is considered to include both the engine and/or motor(s) as well as the drivetrain. Function The function of the drivetrain is to couple the engine that produces the power to the driving wheels that use this mechanical power to rotate the axle. This connection involves physically linking the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scion XB
The Scion xB is a compact car (subcompact car in its first generation) made by Scion (automobile), Scion, a now-defunct fully owned division of Toyota, for the United States market. It is a box-shaped, 5-door hatchback. First generation (XP30; 2003) The first-generation xB was a lightly modified and rebadged version of the Japanese-market subcompact car, subcompact Toyota bB. It was a small hatchback based on the Toyota Platz, Toyota Echo/Toyota Yaris, Yaris platform. The xB was one of two models in the lineup of Toyota's US-exclusive Scion division present at the brand's 2003 launch, the other being the Scion xA, xA, based on the Toyota ist. The car proved to be unexpectedly popular with senior drivers. First-generation xB vs. first-generation bB Only the first-generation models for both the xB and bB are related. Second-generation models are based upon different platforms. To create the first-generation xB, the bB was modified from right- to Traffic directionality, left-han ...

Tesla Roadster (2008)
The Tesla Roadster is a battery electric vehicle (BEV) sports car, based on the Lotus Elise chassis, that was produced by the electric car firm Tesla Motors (now Tesla, Inc.) in California from 2008 to 2012. The Roadster was the first highway legal serial production all-electric car to use lithium-ion battery cells and the first production all-electric car to travel more than per charge. It is also the first production car to be launched into deep space, carried by a Falcon Heavy rocket in a test flight on February 6, 2018. Tesla sold about 2,450 Roadsters in over 30 countries, ''More than 2,350 units sold through June 2012''. ''Sales during the 3Q 2012: 68 Roadsters and 253 Model S.'' and most of the last Roadsters were sold in Europe and Asia during the fourth quarter of 2012. Tesla produced right-hand-drive Roadsters from early 2010. The Roadster qualified for government incentives in several nations.

Vehicle-to-grid
Vehicle-to-grid (V2G), also known as Vehicle-to-home (V2H) or Vehicle-to-load (V2L) describes a system in which plug-in electric vehicles (PEV) sell demand response services to the grid. Demand services are either delivering electricity or by reducing their charging rate. Demand services reduce pressure on the grid, which might otherwise experience disruption from load variations. Plug-in electric vehicles include battery electric vehicles (BEV), plug-in hybrids (PHEV), and hydrogen vehicles. They share the ability to generate electricity. That electricity is typically used to power the vehicle. However, at any given time 95% of cars are parked, while their energy sits unused. V2G envisions sending some of the stored power to the grid (or reducing charge rates to pull less power from the grid). A 2015 report found that vehicle owners could receive significant payments. Batteries have a finite number of charging cycles, as well as a shelf-life, therefore V2G can impact battery l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toyota RAV4 EV
The Toyota RAV4 EV is an all-electric version of the popular RAV4 SUV produced by Toyota until 2014. Two generations of the EV model were sold in California, and to fleets elsewhere in the US, with a gap of almost ten years between them. The first generation was leased from 1997 to 2003, and at the lessees' request, many units were sold after the vehicle was discontinued. A total of 1,484 were leased and/or sold in California to meet the state's mandate for zero-emissions vehicle. A small number were sold or leased in fleet sales in other states. As of mid-2012, there were almost 500 vehicles still in use in California. Production of the second generation EV was limited to 2,600 units during a three-year run, with sales limited to California beginning in 2012. Production ended in September 2014. A total of 2,489 units of the second generation model were sold in California through April 2015. Toyota worked together with Tesla Motors and Panasonic to develop the second generatio ...
