Dynamic power control between multiple e-Chargers

Dynamic Power Control Between Multiple e-Chargers

Dynamic load balancing between multiple e-Chargers is an advanced solution that automatically and efficiently distributes the available power among all chargers, using a smart meter as a reference. This ensures that the total power is properly distributed across all devices, preventing overloads on the electrical network and making the most of the available energy capacity.

It is especially beneficial in installations with electrical limitations, whether due to the contracted power or constraints in the existing infrastructure, such as cable gauge. The system automatically adjusts the power delivered to each charger, adapting to the real conditions of the installation.

In addition, this solution makes it easy to scale the number of installed chargers, allowing for future expansions without the need for complex configuration changes.

Load balancing between e-Chargers with Trydan and Trydan Pro

To simplify setup and allow for more effective monitoring of the installation, having Internet access is recommended. In installations with multiple e-Chargers operating with dynamic power control, it is important that all chargers are connected to the same local network if you want to optimize performance via an Internet connection.

In what ways can multiple Trydan or Trydan Pro units be interconnected?

Option 1: Router Connection (WiFi or Ethernet)

In this configuration, it is not enough for the devices to be on the same local network; they must also be connected through a single router with Internet access, either via WiFi or Ethernet (Ethernet is only possible with Trydan Pro).

It is essential that all devices involved in energy management have an IP address within the same subnet. For example, one charger could have the following IP: 192.168.1.27, another: 192.168.1.45, and another: 192.168.1.38.

To connect via WiFi, you must ensure that the network is stable across all e-Chargers.

If the router does not have enough ports, it must be linked to a central hub or switch with the appropriate number of ports to connect all charging points.

Option 2: Serial Connection

A maximum of ten chargers can be connected in series: one Master and up to nine Extra units.
The connection is made through wiring connected to the charger’s Control Board. There are two possible methods:

1. Using terminals A and B on the Control Board. In the latest versions of the control PCBs, there are 2 ports where devices can be interconnected. To do this, connect the V2C ControlBox 2.0 meter to the Master e-Charger via the RJ45 port using a Category 6 UTP cable, as usual. Then, connect two wires (blue and white/blue) to terminals A and B of the same Master charger and to terminals A and B of the Extra Trydan charger you want to add. Continue this process for each Extra charger (up to 9).

IMPORTANT: This is the recommended method for load balancing.

NOTE: It is essential that the A terminal wire (blue) from the Master charger is connected to terminal A of Extra Charger 1, and the B terminal wire (white/blue) is connected to terminal B of Extra Charger 1. (And so on for the rest). In other words, A terminals must be connected with wires of the same color, and B terminals as well.

2. Using a V2C RJ45 Hub. Para conectar el cable entre el Hub, los e-Chargers Trydan y el medidor V2C ControlBox 2.0, sigue las normas de crimpado T568A o T568B para el conector RJ45. Una vez crimpados los cables, debemos conectar el medidor V2C ControlBox 2.0 en el puerto ‘CDP’ del Hub, el cargador Trydan maestro en el puerto ‘Master’ y el resto de cargadores Extra, en los demás puertos.
To connect the cable between the Hub, the Trydan e-Chargers, and the V2C ControlBox 2.0 meter, follow the T568A or T568B wiring standards for RJ45 connectors. Once the cables are crimped, connect the V2C ControlBox 2.0 meter to the ‘CDP’ port of the Hub, the Trydan Master charger to the ‘Master’ port, and the remaining Extra chargers to the other ports.

If you want to add more than 6 Extra chargers, you must connect another Hub to the last available port.

NOTES:

  • The V2C ControlBox 2.0 meter can be replaced by another Modbus meter.
  • If instead of using the V2C ControlBox 2.0, you use an IP meter (WiFi/Ethernet), it must be configured in the Master charger.

In both types of serial connection (via A and B terminals or via the Hub), the “bias resistors” must be enabled in one device on the communication bus.

Load balancing between e-Chargers with Pole Pro

Although an Internet connection is not mandatory, it is recommended to improve installation monitoring and facilitate configuration. If you choose to connect the e-Chargers to the Internet for better dynamic control among multiple e-Chargers, it is essential that they are connected to the same local network.

The installation must be carried out by qualified and competent technical personnel, who are fully responsible for ensuring compliance with current installation regulations and standards.

What are the possible ways to connect multiple Pole Pro units?

Option 1: Standard router with 4G or fiber

In addition to being connected to the same local network, in this setup the devices must be interconnected through a standard router that has a 4G connection or is connected to an existing fiber-optic network. This router must also have the same gateway configured for all devices that need to share the energy load.

For a standard installation, it is necessary to install a router that generates the local network. This router should be connected to a central hub or switch with a sufficient number of ports for all e-Chargers. If the installation is small and the router has enough Ethernet ports, a hub is not required—the connection can be made directly to the router.

TCP/IP connections should be set up in a star topology, with each charger having its own network cable. The maximum length for UTP cable is 100 meters. If a greater distance is required, the connection must be made using fiber optics.

Option 2: WiFi Connection

Connecting to a WiFi network—with good coverage—can also be used to connect the devices to the router. The only requirement is that the connection must be strong and stable enough to reach all the e-Chargers.

NOTE: If using a WiFi connection, it is important that the Master Pole Pro device is connected to the router via an Ethernet cable to ensure proper load balancing between e-Chargers.

Option 3: Daisy-Chain Connection

Finally, it is possible to daisy-chain the charging points, which helps save on Ethernet cable and simplifies the installation. To do this, a device called the Split-Ethernet—sold separately from Pole Pro—is used.

This device allows the Ethernet cable to be connected to the input of the e-Charger. It includes a USB connector that must be plugged into the appropriate port, and two Ethernet ports: one for the incoming cable from the installation and another for the outgoing cable to the next charger.

The connection starts from the router to the first splitter, as shown in the diagram. This splitter is connected to the power board via an Ethernet cable and a USB connection. Then, a UTP cable runs from the splitter to the next Pole Pro. This wiring pattern is repeated through to the final unit in the chain. For the last device, a splitter is not required; the UTP cable can be connected directly to the control board.

Configuration and activation of dynamic load control for multiple e-Chargers in V2C Cloud

Among all connected charging points, you can enable load balancing only on the devices you choose. If you prefer to prioritize a specific charger and avoid balancing, simply do not activate the feature on that device.

To enable load balancing between multiple e-Chargers, log in to the V2C Cloud app from your smartphone or computer and add the chargers. Then activate Dynamic Load Control on all units.

Make sure the Power Control Type is set to Dynamic. Then, specify the number of e-Chargers to balance, and assign the role to each unit: Master or Extra.

Once power control is activated and configured on all charging points, the Master will automatically detect all connected and active chargers on the network as Extras.

Additionally, the system includes a feature called “Device List (Extras)”, which allows you to view all the secondary devices it communicates with, along with detailed information about each one.

Customize load control to maximize your energy

Customizing load control is crucial to maximize efficiency. Tailoring charging profiles to your specific needs not only saves energy but also optimizes overall consumption. A precise configuration of the charging profiles gives you control over charging times and intensity, resulting in significant energy bill savings.

Proper configuration is essential to get the most benefit from load control.
