In RELAXATION state, temperature changes and applied currents below Quit Current can still trigger changes in the reported StateofCharge(). Similarly, other scenarios can cause differences in true vs reported RemainingCapacity() and FullChargeCapacity() when entering a battery RELAXATION state. To enable convergence between true and reported SOC values, a similar smoothing algorithm is also supported during cell relaxation.
Smoothing during RELAXATION mode can be configured by the SMSYEN and RlxSMen bits in the Pack Configuration Registers.
SMSYNEN | RlxSmEn | Description |
---|---|---|
0 | 0 | No SOC Smoothing during RELAXATION |
0 | 1 | SOC Smoothing enabled during RELAXATION mode, Convergence over time |
1 | 0 | Reserved |
1 | 1 | SOC Smoothing with enabled during RELAXATION mode, Instant Convergence |
The amount of time, the RelativeStateOfCharge() is smoothed during RELAXATION is configured using the Relax Smooth Time parameter.
