Question: The Magne Charge system was produced by a General Motors subsidiary based in what Indiana town?

full_context: Document 1: GM Stir-Lec I: The General Motors Stir-Lec I was a concept hybrid electric car based on the Opel Kadett body in 1969. The power plant consists of 14 lead-acid batteries in the front of the car which transfer energy to a rear-mounted 3 phase electric induction motor, in turn driving the rear wheels. The Stir-Lec I had a top speed of 55 mph . While the car is running, the batteries are constantly recharged by a small Stirling engine in the rear. The engine was allegedly so quiet it was hard to determine if it was running or not, just by sound. Since the Stirling is an external combustion engine, the exhaust has virtually no odor and pollution levels can be made very low.
Document 2: Delco Electronics: Delco Electronics Corporation was the automotive electronics design and manufacturing subsidiary of General Motors based in Kokomo, Indiana. The name Delco came from the Dayton Engineering Laboratories Co., founded in Dayton, Ohio, by Charles Kettering and Edward A. Deeds in 1909. Delco was responsible for several innovations in automobile electric systems, including the first reliable battery ignition system and the first practical automobile self-starter.
Document 3: Detrola Radio &amp; Television Corporation: The Detrola Radio and Television Corporation was an American manufacturer of radios. Founded in Detroit in 1931 by John J. Ross, Detrola became a brand of affordable radios in the midst of the Great Depression. They may well have been the world's most prolific manufacturer of private brand radios for department stores and small retailers, likely building sets under more than 100 different brand names. The company also manufactured large quantities of radios under the Truetone name for Western Auto and Silvertone brand for Sears. Popular models were the "Super Pee Wee" and "Catalin 281" known for being cheap economy sets. At the company's height in 1936, Detrola claimed to be "The sixth largest radio manufacturer in the United States" and had about 1000 employees, and sales representatives in many cities and foreign countries.
Document 4: Magne Charge: Magne Charge is a largely obsolete inductive charging system, also known as J1773, used to charge battery electric vehicles (BEV) formerly made by General Motors, for vehicles such as the EV1, Chevy S10 EV, and other . It was produced by the General Motors subsidiary Delco Electronics. It is still used by a few hundred first generation Toyota RAV4 EV electric vehicles. As these first generation Toyota RAV4 EV electric vehicles retire from the roadways, Magne Charge will be completely obsolete since no existing or future electric vehicles can use it. The 2012 Gen 2 RAV4 EV, as well as the Nissan Leaf and Chevrolet Volt, use J1772 instead of the obsolete Magne Charge.
Document 5: Chevrolet: Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM). Louis Chevrolet and ousted General Motors founder William C. Durant started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918 and propelled himself back to the GM presidency. After Durant's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose," would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929.
Document 6: Canadian Electric Vehicles: Canadian Electric Vehicles Ltd. was first established in 1996 in Errington, British Columbia. During the initial years, its focus was to provide designs, parts and technical support for converting conventional internal combustion vehicles to non-polluting battery powered electric vehicles. Once converted, these vehicles were acquired by a variety of purchasers including federal and provincial governments, industrial companies as well as private individuals. The conversions ranged from three wheeled utility vehicles to house boats as well as various full-sized cars and trucks.
Document 7: Koyo Electronics Corporation Limited: Koyo Electronics (Kōyō Denki) and its subsidiary Koyo Electronics Industry (Kōyō Denshi Kōgyō), often collectively referred to as just Koyo, are Japanese electronics companies based in Kodaira, Tokyo that manufactured radios since 1955 until 1973, and now its subsidiary manufactures industrial electronics devices and factory automation control systems.
Document 8: EVcort: EVcort The EVcort was an experimental electric car produced from 1981 to 1994 by Electric Vehicle Associates of Cleveland OH and later by Soleq Corp. of Chicago IL. It consisted of a stock body and transmission from the Ford Escort, refitted with an electric propulsion system, every component of which was engineered and manufactured specifically for the car. It incorporated features such as regenerative braking and a multistep charging algorithm, that are common on modern electric vehicles but were quite innovative at the time. The intent was to produce a practical alternative-fueled vehicle with performance comparable to gasoline-powered cars, but like many electric vehicles of that era, the EVcort proved far too expensive to be commercially viable. Nevertheless, the it was used extensively by a variety of institutions for electric vehicle demonstration and testing programs.
Document 9: General Motors Rotary Combustion Engine: The General Motors Rotary Combustion Engine (GMRCE) is an internal combustion Wankel engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. In November 1970, GM paid $50 million for initial licenses to produce their version of the Wankel rotary engine, and GM President Ed Cole initially projected its release in three years. Chevrolet, with impetus from Pete Estes and John DeLorean, as well as Ed Cole worked on the Wankel. Bob Templin was the chief executive in charge of rotary-engine research at the GM Tech Center in Warren, Michigan, but Ed Cole would leave his office in Detroit twice a week for the trip to Warren, taking charge of the program. The engine was initially targeted for an October 1973 introduction as a 1974 Chevrolet Vega option.
Document 10: Plug-in electric vehicle fire incidents: Several plug-in electric vehicle fire incidents have taken place since the introduction of mass-production plug-in electric vehicles in 2010. Most of them have been thermal runaway incidents related to the lithium-ion batteries and have involved the Zotye M300 EV, Chevrolet Volt, Fisker Karma, Dodge Ram 1500 Plug-in Hybrid, Toyota Prius Plug-in Hybrid, Mitsubishi i-MiEV and Outlander P-HEV. Most hybrid electric vehicles available in the market today use nickel-metal hydride batteries which do not pose the same risk of thermal runaway as lithium-ion batteries.
Document 11: Chevrolet Volt: The Chevrolet Volt is a plug-in hybrid car manufactured by General Motors, also marketed in rebadged variants as the Holden Volt in Australia and New Zealand, and with a different fascia as the Vauxhall Ampera in the United Kingdom and as the Opel Ampera in the remainder of Europe.
