Abstract

A method for operating a battery system having multiple battery packs. The method includes decoupling the output of a discharged battery pack from the vehicle load, reducing the voltage between an output of a charged battery pack and the vehicle load prior to coupling the output of the charged battery pack to the vehicle load.
