Monitoring IC Chip for Battery Management Unit

摘要

A monitoring IC chip is designed to detect at least one operating variable from at least one battery cell or from a battery module, which comprises a predetermined number of battery cells, and which can be connected, together with a multiplicity of monitoring IC chips of the same type, to a first bus in a daisy-chain topology such that successive monitoring IC chips in the daisy-chain topology are situated in a rising voltage chain, wherein one of the monitoring IC chips connected to the first bus can be used as a base monitoring IC chip which is designed to use a second bus to communicate with a controller. The monitoring IC chip can be used as the base monitoring IC chip either at a lower end or at an upper end of the voltage chain on the basis of a configuration or an interconnection.
