The
traction - drive system typically consists of a boost converter (which steps up
voltage when the electronic circuit requires a higher operating
voltage than the battery can provide alone), two inverters (which take direct current (DC)
voltage and convert it to alternating current (AC)-RRB-, and
electric motors to provide motive power (pdf).
Targeted to achieve AT - PZEV (Advanced Technology Partial Zero Emissions Vehicle) status, C - MAX Energi pairs a high -
voltage lithium - ion battery and
electric traction motor with a high - efficiency Atkinson - cycle gasoline engine.
