DYNAMIC LOAD BALANCING

TeltoCharge have the ability to communicate with dedicated smart energy meter and regarding to its readings, adjust used electrical power. Such functionality allows to protect house electrical grid from overload in peak hours and optimize energy usage to meet user habits. Smart energy meter should always be installed in source electrical cabinet as showed below.

Smart meter and TeltoCharge communication

Smart meter and TeltoCharge communicates via Modbus RS-485 protocol. In order to achieve smooth communication, it is recommended to use communication cable according to this protocol. Check example below

Note: Communication cable should be integrated with power cable.

Supported energy meters

In order to strive for wider applicability and compatibility, we constantly test and add new supported devices into list. All of the supported Energy meters and schematics how to connect them are provided below.

LOAD BALANCING CONFIGURATION

To ensure everything works correctly, please apply the following setup :

Open user menu
Open "Installer Menu"
Open "Dynamic Load Balancing" menu
Enable "Load Balancing"
If smart meter is connected with RS485 wires, press "Search For Device"
*ONLY If TeltoCharge is unable to identify energy meter - use "Manual Setup"

PHASE BALANCE EXPLANATION

TeltoCharge has an advanced functionallity to detect car's charging type and if required switch phases during midcharge.

Adaptation to the car's charging capability

If the charger is set for 3phase charging, but plugged car could only draw current from one phase, TeltoCharge will switch to one phase mode after a short period of time

Phase balance during lack of power

When the smart meter is detecting that there is less than 6A for each phase, charging station will switch from 3phase mode to 1phase mode until 6ampers will be available for all phases
