h) repeat 5.5.2c) to 5.5.2 g). the discharge amounts are Q02 and Q03 respectively,
and then the arithmetic mean value of the three discharge amounts is Q0. If the
the available capacity of the battery system. If any deviation between Q01, Q02
or Q03 and Q0 is not less than 2%, then the available capacity test process is
repeated until the discharge amounts for the three consecutive times meet the
criteria for the available capacity verification.
Note. If the manufacturer has the recommended charge and discharge
specifications, it can be used directly in the available capacity test, replacing the
relevant contents of 5.5.2 c) to 5.5.2 d) and 5.5.2 a) respectively, which shall be
stated in the test report.
