Abstract
An integrated multiple voltage battery system includes a first pair of output terminals, a second pair of output terminals, a plurality of first battery cells connected in series with each other and operatively connected to the first pair of output terminals, at least one second battery cell operatively connected to the second pair of outlet terminals, and a plurality of switches, the plurality of switches arranged such that each first battery cell in the plurality of first battery cells can be selectively placed in parallel with the at least one second battery cell while electrically isolating the other of the plurality of first battery cells from the at least one second battery cell, wherein each of the plurality of first battery cells has a nominal open cell voltage which is about the same as a nominal open cell voltage of the at least one second battery cell.
