A team led by Dr Jeremy Michalek at Carnegie Mellon University has examined plug-in hybrid electric (PHEV) battery life under various conditions. Their findings, published in the Journal of Power Sources, revealed that aggressive driving, especially in warmer conditions with "no thermal management", can reduce battery life by up to between 1.5 and 6. The research also found batteries operating in milder climates last 73–94% longer, while air cooling can increase battery life by a factor ranging two-thirds. In addition, the use of a "blended gas/electric-operation control strategy" can quadruple battery life.
