Dynamic power control for one or multiple e-Chargers

The most common way to manage energy through power control involves integrating a home, business, or facility with one or multiple additional e-Chargers.

Dynamic power control is an advanced energy management feature that detects real-time energy usage in your home or business to charge your electric vehicle at maximum power, thus preventing overloads. By using devices capable of measuring consumption, the e-Charger can monitor, in real-time, the power demanded (or energy generated if you have photovoltaic energy) and make use of it accordingly. This means it can balance the charger’s power with the excess power from the home or business, or from the photovoltaic installation, if available.

Which e-Charger do you use for dynamic power control?

Trydan

Trydan Pro

Pole Pro

Dynamic power control with Trydan or Trydan Pro

What are the available methods for performing dynamic power control with Trydan or Trydan Pro?

V2C ControlBox (V2C 2.0 meter)

The V2C ControlBox device is convenient, intuitive, and easy to install. It is included when purchasing Trydan or Trydan Pro, along with a clamp that connects to the main supply line of the property (covering home consumption + electric vehicle).

With a single device, it offers readings of up to six channels, allowing measurements in standard installations, whether single-phase or three-phase, even if photovoltaic energy is available.

There is an earlier version, V2C 1.0, which is no longer marketed, although it may still be found in some installations.

How to install the V2C ControlBox meter?

WiFi meters

This is an alternative when running an Ethernet cable from the e-Charger to the V2C ControlBox is not feasible. The WiFi meter and the charger must be connected to the same WiFi signal. You can choose either Shelly or Wibeee, two of the most well-known WiFi meters.

How to install the Wibeee meter?

If you have photovoltaic energy and your inverter is connected to a secondary panel (or the charger is directly connected to the meter) and it is not possible to measure its output, this is the appropriate meter. It can measure the direction of current flow, enabling the use of all charging modes offered by Trydan due to its bidirectional reading capability.

Wired meters

Another option is wired meters, including models such as Carlo Gavazzi, Chint, Eastron, or Phoenix Contact.

These can be used when you have photovoltaic energy but cannot install the V2C ControlBox (due to the inverter being connected to a different panel than the charger) and WiFi connection is also unavailable (if you have a suitable WiFi signal, a WiFi meter is preferable).
These meters do not allow solar generation to be viewed on V2C Cloud; however, all solar energy operation modes function correctly.

Direct connection with the inverter

Our Trydan and Trydan Pro e-Chargers, industry pioneers, are the first chargers to enable direct connection with a solar inverter, enhancing system efficiency and simplifying installation and maintenance.

This type of connection can be established via WiFi, Ethernet, or RS485 with inverters such as Huawei, Kostal (Piko, KSEM, Plenticore), Goodwe, Solis, Greenheiss, SAJ, Fronius, Victron, SolarEdge, Ingeteam, etc. Discover how to connect your e-Charger model to photovoltaic energy.

A direct connection is essential when the inverter is compatible with Trydan to obtain accurate battery readings.

Photovoltaic integration

Via MQTT protocol

Additionally, measurements can be performed using the MQTT protocol, which enables efficient communication between the e-Charger and other devices, allowing precise and swift control of the electric vehicle charging process.

How to configure MQTT

The installation must be carried out by competent and qualified technical personnel who are fully responsible for compliance with installation provisions and existing regulations.

NOTE: It is important that the loose UTP wires are insulated and do not make contact with each other.

IMPORTANT NOTE: Wired meters used for the operation of dynamic power control must be used exclusively for this purpose. The installation of these meters must follow the electrical diagrams or instructions as outlined in the manual for each device.*

* Some meters indicate that the communication terminal B is positive (B+) and terminal A is negative (A-). To connect correctly, you should connect pin 4 of the RJ-45 connector from Trydan to terminal A- and pin 5 of the RJ-45 connector from Trydan to terminal B+ of the meter.

** If you already have a meter, you must ensure that it is configured with the ‘Modbus’ protocol type, a baud rate of ‘9600’, and a communication address of ‘1’.

Steps to follow for configuration and activation

Once the installation of the relevant meter has been completed, it is essential to optimally configure the dynamic power control. Without this step, the e-Charger will not automatically and dynamically allocate any surplus energy from the home or business to the electric vehicle charging.

This configuration can be carried out via Bluetooth or WiFi (if available) and accessed through the V2C Cloud app or on a computer at www.v2c.cloud, using your user credentials and password. In both cases, follow the instructions provided in the image.

* The meter installation must be carried out by a professional. The V2C Control Box will be used by default if no alternative is available. There are various versions of meters; therefore, it is crucial to select the appropriate meter, considering the existing installation type, and to save the configuration.

Custom power control configuration

Customising power control through charging profiles is vital for improving efficient energy management.

By adapting the system to your specific needs, you not only maximise the efficient use of energy but also gain complete control over the charging profiles, allowing you to adjust timings, intensity, and charging mode. This results in savings on your energy bills, optimising every resource and elevating energy efficiency standards to a new level.

Customise power control

If an error occurs when activating dynamic power control at the Trydan or Trydan Pro charging point, a code corresponding to that error will appear on the charger’s display. Refer to the connection error diagnostics to ensure proper use of dynamic power control.

Dynamic power control with Pole Pro

In what ways can dynamic power control be implemented with Pole Pro?

Pole Pro meter

The energy meter provided by V2C uses open toroidal clamps. For optimal operation, this meter must be installed at the main supply of the entire installation. This allows for the measurement of consumption from both the charging points and the rest of the installation, including the possibility of integrating a photovoltaic system that injects energy.

If you purchase the meter directly from V2C, please note that it comes preconfigured for use. Additionally, you can choose clamps rated at 250, 400, or 600 amperes, depending on the specific needs of your installation.

IMPORTANT NOTE: Wired meters used for the operation of dynamic power control must be used exclusively for this purpose. The installation of these meters must follow the electrical diagrams or instructions as outlined in the manual for each device.

If you already have a meter, ensure that it is configured with the protocol type ‘Modbus’, a baud rate of ‘9600’, and a communication address of ‘1’.

To carry out the installation of the meter, follow these steps:
  1. Power the meter with the neutral and the corresponding phases at the upper terminals.
  2. You only need two wire connections to establish Modbus communication between the meter and the e-Charger Master. The wire belonging to pin 4 of the charger’s RJ-45 must be connected to terminal 12 (A-), and the wire corresponding to pin 5 must be connected to terminal 11 (B+).

NOTE: To establish the Modbus connection, any shielded cable designed for this purpose, which contains a twisted pair of wires, can be used. However, a convenient option is to use UTP cable due to its practicality.

If you choose to use UTP cable, we recommend using a shielded Category 6 cable and employing the same twisted pair to minimise noise as much as possible. Additionally, it is important that the loose UTP wires are insulated (properly crimped) and do not make contact with each other.

Adapting power control using charging profiles is crucial for more efficient energy management.

By personalising the system to your specific needs, you not only ensure a more efficient use of energy but also gain complete control over the charging profiles, allowing you to adjust timings, intensity, and charging modes.
