O2Micro, a global leader in the design, development
and marketing of high-performance integrated circuits and
solutions, was granted a U.S. patent for its Battery Management Systems
(BMS) with Vertical Bus Circuits.
A BMS monitors battery modules to ensure safe operation and to maximize
capacity and battery cycle life via connection to a host
microprocessor. Vertical bus circuits enable the host processor to
communicate with the battery management chips in a BMS. This invention,
issued 24 claims under U.S. patent number 8,907,625, ensures an
efficient BMS with low operating power consumption and system costs.
Bill Densham, strategic marketing director, O2Micro, commented, "This
invention provides protection to battery modules in the battery pack
while minimizing part count and system cost."
