Battery supplier A123 Systems has unveiled two new batteries specifically optimized for automotive applications. One of the new cells is configured for high power applications in regular hybrid
configurations while the other is biased toward higher energy capacity for plug-in hybrid
vehicles. The latter cell is being used in the plug-in hybrid development program
for the Saturn Vue
The PHEV cell is designed to be discharged to a lower level than the power battery so that the plug-in hybrid can go farther on battery power alone. Both cells are designed to be more robust over the wider range of operating conditions that cars encounter in the real world while also lasting 150,000 miles and ten years.
