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.
The AC-150 has been used in a variety of applications such as the BMW
Mini E,
Foton Midi taxi and a USPS LLV demo vehicle. AC Propulsion was a pioneer in
Vehicle to grid or V2G systems,
with their second generation AC-150

Connection with Tesla Motors
Martin Eberhard
Martin Forest Eberhard (; born 1960) is an American engineer and entrepreneur who co-founded Tesla, Inc. (then Tesla Motors) with Marc Tarpenning in July 2003, where Eberhard was its original CEO serving until late 2007. In 2015, he was induct ...

Scion xB
The Scion xB is a five-door compact hatchback that was produced by Scion (automobile), Scion, a former marque of Toyota. Produced from the 2004 to 2015 model years, it was one of the two launch models of the Scion marque, alongside the Scion xA. ...
called the
eBox, Martin Eberhard and Marc Tarpenning incorporated Tesla Motors to pursue the idea of building an electric roadster in the spirit of the tzero.

later test drove the tzero as well, and he also encouraged AC Propulsion to commercialize the vehicle. Tom Gage again deferred, but put Elon Musk in contact with Martin Eberhard which led to Musk becoming Tesla Motors' first major investor through Series A funding.
Before Tesla Motors developed its Roadster's proprietary
powertrain
In a motor vehicle, the powertrain comprises the main components that generate engine power, power and deliver that power to the road surface, water, or air. This includes the internal combustion engine, engine, transmission (mechanics), trans ...

, thus reducing mass, complexity, and cost. Tesla then designed and built its own power electronics, motor, and other drivetrain components that incorporated this licensed technology from AC Propulsion.
Given the extensive redevelopment of the vehicle, Tesla Motors no longer licenses any proprietary technology from AC Propulsion.
