AC Propulsion Tzero
The tzero is a handmade battery electric vehicle, electric sports car designed and built in very limited numbers by the U.S. company AC Propulsion in the early 2000s. It was the direct predecessor of the Tesla, Inc., Tesla line of electric cars. The tzero was based on the Piontek Sportech kit car, which consists of a fiberglass body built over a reinforced steel space frame with Double wishbone suspension, double wishbone independent suspension and rack and pinion steering. AC Propulsion added the AC Propulsion#Vehicles using an AC Propulsion electric drivetrain, AC-150 drivetrain, a single-speed electric system with an overall gear ratio of 9:1. Launched in January 1997, only three prototypes were built and plans for commercial production were dropped in mid-2003. The name comes from Tzero, ''t''0, the mathematical symbol for a starting point in time. Due to high production costs, AC Propulsion ceased to produce the tzero. Only three were built, and as of 2017 only 1 survived. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AC Propulsion
AC Propulsion is a San Dimas, California, USA company founded in 1992 by Alan Cocconi, Wally Rippel, and Paul Carosa, that specializes in alternating current-based drivetrain systems for electric vehicles. It offers AC-induction traction motors. The company produces electric vehicle drive systems featuring high performance, high efficiency induction motors and integrated high power battery charging. Previously, they built an electric sports car, the tzero and the eBox, an electric conversion based on the Scion XB. They also develop prototype electric vehicles for OEM customers. History Founder Alan Cocconi designed and built the controller used in the original GM Impact, which later became the GM EV1. ACP introduced the first AC-100 in 1992 and the AC-150 150 kW (200 hp) integrated drive system in 1994.

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...

AC Propulsion EBox
The eBox is a conversion of a Scion xB hatchback into a battery electric vehicle produced by the American company AC Propulsion. History AC Propulsion executives announced their intention to convert Scion to battery electric vehicles in October, 2003. Company executives stated that the Scion xB was chosen in part due to its boxy shape which allows for good placement and installation of a battery pack. The availability of a suitable battery was said to be an important step in allowing for the announcement of the program. Suitability requirements included that the battery be widely available ("off the shelf"), in volume, without danger that supply would be cut off or be overly limited. Thousands of lithium-ion batteries, of the 18650 variant, were proposed as suitable for the rechargeable battery system. The prototype eBox was unveiled in Santa Monica, California on August 18, 2006. The prototype used a battery pack consisting of 5,300 Li-ion cells arranged into 100 blocks of 5 ...

Scion XB
The Scion xB is a compact car ( subcompact car in its first generation) made by 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 Toyota bB. It was a small hatchback based on the Toyota Echo/ 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 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 left-hand drive, the front passenger area was also changed significantly with the bB's front bench s ...

Battery Pack
A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles. Components of battery packs include the individual batteries or cells, and the interconnects which provide electrical conductivity between them. Rechargeable battery packs often contain a temperature sensor, which the battery charger uses to detect the end of charging. Interconnects are also found in batteries as they are the part which connects each cell, though batteries are most often only arranged in series strings. When a pack contains groups of cells in parallel there are differing wiring configurations which take into consideration the electrical ''balance'' of the circuit. Battery regulators are sometimes used to kee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kilometre
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre ...
