🎯 Purpose
By default, the load manager always tries to allocate the full charger limit.
The Dynamic Allocation feature changes this behavior to allocate the actual power the vehicle is pulling, plus an adjustable buffer.
This way, the load manager can redistribute the available current to charge points that demand more power.
Dynamic allocation is only relevant to charge points in the OCPP state Charging.
⚙️ Configuration Parameters
| Parameter | Type | Description |
|---|---|---|
| ⏳ Activation Timeout | Number (ms) | Time after charging starts before the feature becomes active |
| ➕ Buffer Value | Number (A) | Additional allocation on top of actual charging current |
| 📏 Dead Band | Number (A or kW) | Threshold beyond which the load manager will reallocate power |
| 📊 Average Window | Number | Number of values used to calculate the moving average |
💡 Example Case
Scenario: Charge point with 100 kW limit
Configuration:
- ⏳ Activation Timeout = 60000 ms (1 min)
- ➕ Buffer Value = 10 kW (~15 A)
- 📏 Dead Band = 3 kW (~4.5 A)
Process:
- The charge point enters the Charging state and is initially allocated 100 kW. The Activation Timeout prevents limitation for the first minute.
- After 1 minute, the charger has ramped up to 60 kW. The feature adjusts the allocation to 70 kW (60 + 10 buffer).
- Whenever the actual mean + buffer goes outside the ±3 kW dead band, the load manager reallocates to the new calculated value.
- Over the next 2 minutes, the charger increases to 70 kW, and the allocated value follows this increase plus the 10 kW buffer.
- At minute 6, the actual power decreases. The allocated value follows it down, until the charge point leaves the Charging state at minute 10. The allocation will not drop below the minimum set value.
