CMU(Cell Monitoring Unit)

A unit that monitors lithium-ion battery cells

Functions * Precisely monitors multiple batteries (voltage, tempperature) and sends data to higher ECU. * Corrects voltage fluctuations of each battery by order of higher ECU

Characteristics * Capable of precision voltage detection in mV order * Multiple CMUs can be connected with minimum wiring, allowing for monitoring multiple batteries through inter-communication * A circuit design technology that allows for stably monitoring batteries in any environment (high/low temperatures, noise)


mV Order detection precision

Minimized harness due to data transceiver technology among multiple CMUs using daisy chains

An insulation circuit design that works under high voltage

A circuit design that does not get influenced by noise even in a high current environment
