The charging station supports Dynamic Load Management (DLM). Using DLM, the charging system safely balances energy consumption between your electric vehicle, charging station and other devices in your internal electricity grid. The functionality enables adjusting the current limit based on real-time measurements and signals that enhances the functionality of the EV charging station by providing intelligent control over charging power.
Benefits of using DLM
Optimised energy consumption of existing infrastructure.
Reduced charging and operational costs.
Local consumption of renewable energy sources.
Future-proof and grid-friendly charging infrastructure.
Required devices for DLM to function
Standalone charging station
For DLM to function in a standalone INCH Core charging station, an external metering device must be used:
INCH Core Load Guard (supports wireless connection), or
an external electricity meter* supporting Modbus RTU communication via RS-485 wired connection, or
combination of the INCH Core Load Guard and an external electricity meter* supporting
Modbus RTU communication via RS-485 interface,
P1 communication via the P1 port, or
TIC communication via the TIC port.
* Refer to the list of electricity meters supported by the INCH Core charging station.
The INCH Core Load Guard supported by INCH Core charging station is not available yet and will be available soon.
Cluster of charging stations
For DLM to function in a cluster of charging stations, an external system/device (e.g., Brain), where DLM logic is running, must be used.
The INCH Core charging station currently does not support clustering, but it will in the future.
Configuration
DLM configuration can be set via the INCH Core app or a central system (e.g., EMSP).
1. Enable DLM via the Dynamic load management page of the INCH Core app, or a central system if applicable.
2. Select the type of your external metering device and set its parameters correctly.
INCH Core Load Guard
To configure Load Guard for DLM to function with the charging station, refer to the INCH Core Load Guard guidelines.
External electricity meter
When choosing an external meter as the external metering device of the charging station for DLM to function, the meter must be:
connected to the charging station via the RS-485 interface connection as required in the /wiki/spaces/EKC/pages/3702784128 and the meter documentation,
configured in such a way that the charging station can be able to communicate with it.
To ensure successful one-way communication from the station to the meter, the station's configuration must match the following parameters of the meter:
Address
Baud rate
Data bits
Parity
Stop bit
When you select your meter type from the dropdown list in the INCH Core app, the listed parameters can already be pre-configured. However, the actual values of these parameters may differ from the default values. It's important to verify and set the correct actual values accordingly.
