Scalable modular design of a 48-volt li-ion battery management system

摘要

The present invention provides a battery control system for controlling a battery pack that is formed by a plurality of battery cells. The battery control system comprises: a detecting circuit for detecting at least one operation parameter of the battery pack; an activating circuit, which receives the at least one operation parameter from the detecting circuit, for generating a first control signal when the detected at least one operation parameter exceeds or is below at least one critical-level threshold; a supervision unit, which receives the at least one operation parameter from the detecting circuit, for managing the battery pack and generating a second control signal when the at least one operational parameter exceeds or below at least one cap-level threshold; a switching circuit, which receives the first control signal from the activating circuit and/or the second control signal from the supervision unit, for connecting the battery pack to and disconnecting the battery pack from an power output in response to the first control signal and/or the second control signal.
