Two Argonne teams win pitch competition, advance to national Lab-Corps training programApril 24, 2015

On April 17, the judges chose these two technologies from a pool of six finalists to participate in the national Lab-Corps training program.

2012 Toyota Prius

The MY2012 Toyota Prius PHV is the first production iteration of Toyota's hybrid system to be produced as a plug in electric vehicle, with a 4.4kWh lithium-ion battery. This vehicle includes a 1.8L Atkinson-cycle engine, two electric machines (one motor, one generator) with a power-split device used to control the blended allocation of energy between the two power paths.

2012 Chevrolet Volt

The Chevrolet Volt is the first production extended range electric vehicle (EREV) released by General Motors, arriving in the model year of 2011. The Volt is equipped with a 16 kWh lithium ion battery, which powers two AC motors: one 111 kW traction motor and one 55 kW motor/generator. During charge sustaining operation, a 1.4L gasoline engine powers the 55kW motor/ generator as a series hybrid design.
