Abstract
A battery including a first control circuit and a plurality of modules arranged in series between first and second terminals, each module including electric cells and switches coupling the cells to third and fourth terminals and a second switch control circuit. The battery includes a first data transmission bus coupling the first control circuit to each second control circuit and a second data transmission bus coupling the first control circuit to each second control circuit. The first control circuit is capable of transmitting first data to the second control circuits over the first bus at a first rate and is capable of transmitting second data to the second control circuits over the second bus at a second rate smaller than the first rate.
