Claim 14:
15. A controller area network/universal asynchronous receiver transmitter (CAN/UART) translator module comprising:
a UART interface configured to connect a plurality of battery cell monitoring modules, wherein the plurality of battery cell monitoring modules are connected to form a daisy chain via a data line;
a CAN transceiver for connecting a battery monitoring unit via a CAN bus line; and
a logic circuit configured to:
transmit and receive a set of digital messages using asynchronous serial data transmission via the data line, wherein the set of digital messages each comprise a multiplicity of frames, comprising: which each comprise
an identification (ID) frame,
one or more data frames, and
a checksum frame including a checksum value calculated based on the data included in the ID frame and the one or more data frames; and

generate a CAN message based on a received digital message of the set of digital messages by:
inserting data included in the one or more data frames and the checksum frame in a data field of the CAN message; and
inserting an identifier included in the ID frame into an ID field of the CAN message; and

transmit the CAN message via the CAN bus line.
