A battery management chip may include a battery management unit and a vertical bus circuit. The battery management unit can monitor a cell status of multiple cells in a battery module coupled to the battery management chip in response to an instruction from a host processor. The vertical bus circuit may transfer the instruction from the host processor to the battery management unit. The vertical bus circuit may include a first receiver, a command processor and a first transmitter. The first receiver can receive a first pair of differential input data signals. The command processor can process the first pair of differential input data signals. The first transmitter can output a first pair of differential output data signals.

A system may include multiple chips and a host processor. The host processor can be coupled to the multiple chips and send an enumerate command. The multiple chips can propagate an enumerate packet including the enumerate command from chip-to-chip, and each chip can use information in the enumerate packet to determine its own unique address.

Battery management systems with enumerating circuits

A method and apparatus for optimizing access to memory, wherein the method includes the steps of receiving a first request for access to a memory, receiving at least two additional requests for access to the memory, and determining a first clock overhead associated with the first request for access to the memory. The method further includes the steps of determining an additional clock overhead associated with each of the at least two additional requests for access to the memory in conjunction with the first request, determining a combination of requests that can be processed together using an optimized overhead, and processing the combination of requests as a single request with the optimal overhead.
