First Claim
1. A battery system comprising:
- a first system terminal;
a second system terminal; and
a plurality of battery strings coupled in parallel between the first system terminal and the second system terminal, wherein individual ones of the battery strings comprise a plurality of rechargeable batteries coupled in series between the first system terminal and the second system terminal,wherein individual ones of the battery strings are configured to operate in an engaged mode of operation where the individual battery string is electrically coupled with the first and second system terminals and configured to at least one of supply and receive electrical energy with respect to the first and second system terminals and a disengaged mode of operation where the individual battery string is configured to not supply nor receive electrical energy with respect to the first and second system terminals.
