Design Capacity is used for compensated battery capacity remaining and capacity when fully charged calculations are done by the gauge. It is also used for constant-current model for Impedance Track algorithm when Load Mode is 0 (constant-current) and Load Select is 4 (Design Capacity/5 for constant discharge). The CONTROL_STATUS [LDMD] bit indicates the Impedance Track algorithm is assuming constant-current model when cleared.
Design Energy is used for compensated battery capacity remaining and capacity when fully charged calculations are done by the gauge. It is also used for constant-power model for Impedance Track algorithm when Load Mode is 1 (constant-power) and Load Select is 4 (Design Energy/5 for constant discharge). The CONTROL_STATUS [LDMD] bit indicates the Impedance Track algorithm is using constant-power model when set.
These values should be set based on the battery specification. See the data sheet from the battery manufacturer.
