The column names are useful when data is viewed with spreadsheet software; spaces are added after
each comma or tab to aid readability. These spaces are not present in the actual log file and all commas
are tabs in the .tsv file. The “BalanceEnable” column only contains data when balancing is enabled and
turned on. The data in such a case is the value of the Balancing Enable register at addresses 20 and 21
(see the bq76PL455A-Q1 data sheet (
) for additional information regarding this register). The
same comment applies to the four data samples below. The content of the fault registers is recorded
under the FSummary and xxxF headings. Fault data are presented in the form: register_address:
register_value_in_hex. For example, 82: 0000 means the register at address 82 (that is, the Fault
Summary register), contains a value of 0000 hex. Consult the data sheet for more details on the various
fault registers referred to by address in the log file; bit definitions for the various fault regsiters are
detailed in the register descriptions in the data sheet.

Internal temperature is not being logged in this example. “3814” in the intervals at 0.999000 seconds and
1.499000 seconds indicate that cells 3, 5, 12, 13 and 14 were being actively balanced. “3814” is a
hexadecimal representation of the binary value 0011 1000 0001 0100. Each ‘1’ bit represents a cell
being balanced, each ‘0’ bit represents a cell not being balanced. (Refer to the description of the
Balancing Enable register in the bq76PL455A-Q1 data sheet (
) for additional information.)
