Abstract
Various examples are directed to integrated circuits and/or controllers for battery packs. An integrated circuit for managing at least a portion of a battery pack comprises a first cell controller. The first cell controller may comprise a first switch system, a first local controller, a first receive terminal to receive a first command from a preceding cell controller, and a first transmit terminal to send the first command to a succeeding cell controller. The first switch system may comprise two pairs of switches to couple a first battery cell to a pair of output terminals in an H-bridge configuration. The first local controller may control the first switch system to selectively connect and disconnect the first battery cell to the pair of output terminal.
