DLM Case Studies

This section provides detailed case studies for Dynamic Load Management (DLM) with multiple configuration examples of increasing complexity.

For specialized DLM implementations, see also:

1. Small Fleet Charging​

1.1. Scenario​

A delivery company has five electric vans charging overnight. The site has a 200A power limit, but if all vans charge at full power at the same time, the system could overload.

1.2. How DLM Helps​

  • Distributes the available 200A across all five chargers.
  • If only a few vans are charging, they receive more power.
  • If all five vans charge at once, power is evenly shared to prevent overloads.

1.3. Configuration Example​

Location in Config UI
Parameter
Value
Set on
Info
#
Load Management > Dynamic Load Management
Dynamic Load Management Mode
DLM Master
Main Charging Station
Manages power allocation.
#
Load Management > Dynamic Load Management
EVSE Sub-Distribution Limit (L1/L2/L3)
200/200/200
DLM Master
Prevents exceeding grid limit.
#
Load Management > Dynamic Load Management
Dynamic Load Management Mode
DLM Slave
All Other Charging Stations
These chargers follow the master's allocation.

2. Public Charging Hub with Time-Based Priority​

2.1. Scenario​

A public charging station has 10 EV chargers, but the site can only support a maximum of 400A. The station wants to prioritize fast charging during peak hours and spread out charging loads at night.

2.2. How DLM Helps​

  • Distributes available power dynamically.
  • Prioritizes chargers during the day for faster charging.
  • Slows down charging at night when demand is lower.

2.3. Configuration Example​

3. Implementation Considerations​

These case studies demonstrate the flexibility and scalability of DLM systems across different scenarios. When implementing your own solution:

  • Start with the simplest configuration that meets your needs
  • Consider future expansion requirements when selecting DLM modes
  • Document your power distribution hierarchy and limits
  • Test the system during off-peak hours initially
  • Monitor the system's performance during the first weeks of operation
