PRODUCTION DATA.
Load Select defines the type of power or current model to be used to compute load-compensated capacity in the Impedance Track algorithm. If Load Mode = 0 (Constant Current), then the options presented in Table 1 are available.
Load Select Value | CURRENT MODEL USED |
---|---|
0 | Average discharge current from previous cycle: There is an internal register that records the average discharge current through each entire discharge cycle. The previous average is stored in this register. |
1 (default) | Present average discharge current: This is the average discharge current from the beginning of this discharge cycle until present time. |
2 | Average current: based off the AverageCurrent() |
3 | Current: based off of a low-pass-filtered version of AverageCurrent() (τ = 14 s) |
4 | Design capacity/5: C Rate based off of Design Capacity /5 or a C/5 rate in mA. |
5 | Use the value specified by AtRate() |
6 | Use the value in User_Rate-mA: This gives a completely user-configurable method. |
If Load Mode = 1 (Constant Power) then the following options are available:
Load Select Value | POWER MODEL USED |
---|---|
0 | Average discharge power from previous cycle: There is an internal register that records the average discharge power through each entire discharge cycle. The previous average is stored in this register. |
1 | Present average discharge power: This is the average discharge power from the beginning of this discharge cycle until present time. |
2 | Average current × voltage: based off the AverageCurrent() and Voltage(). |
3 | Current × voltage: based off of a low-pass-filtered version of AverageCurrent() (τ = 14 s) and Voltage() |
4 | Design energy/5: C Rate based off of Design Energy /5 or a C/5 rate in mA. |
5 | Use the value specified by AtRate() |
6 | Use the value in User_Rate-Pwr. This gives a completely user-configurable method. |
