# Charge to min SOC -> Hold min SOC
|
|
|
|
Initial State: `Charge to min SOC`
|
|
Target State: `Hold min SOC`
|
|
|
|
## Test Procedure
|
|
|
|
1. The battery is discharged below 20% SOC
|
|
2. `Min SOC` is set to 20%
|
|
3. A production deficit is simulated by setting `Grid setpoint` to a negative value (-2000W)
|
|
4. Wait until the `SOC` stabilizes slightly above `Min SOC`
|
|
|
|
## Expected Outcome
|
|
|
|
The system assumes the `Charge to min SOC` state and charges with high power (~2000W), until it reaches `Min SOC`.
|
|
Once it reaches `Min SOC` it does the following:
|
|
|
|
- it changes into the `Hold min SOC` state
|
|
- the `SOC` stabilizes between 20% and 20.5%
|
|
- the `SOC` does not fluctuate by more than 0.1% once it has stabilized
|
|
- charging power does not fluctuate by more than 250W once it has stabilized
|
|
|
|
## Tested Outcome
|
|
|
|
The system reacted as expected and switched to `Charge to min SOC` and charged as fast as possible till reaching the `Min SOC`.
|
|
Once the `Min SOC` is reached, the battery switches to `Hold min SOC`, entering a stabilisation state for around 10 minutes where
|
|
the charging power remains positive and up to 270 W. After approximately 10 minutes, the battery reaches the final stabilised
|
|
state where the charging power fluctuates in range of +-75W. The `SOC` fluctuates between 20% and 21%, slighty favouring the later.
