Dynamic Power Control

Dynamic power control is a Trydan functionality that detects in real time the energy usage in your home in order to charge your electric vehicle at maximum power, thus avoiding overcharging. This is possible thanks to a device included with the e-Charger, called “Meter”, which is currently marketed in the V2C 2.0 version.

This mechanism allows consumption to be measured so that Trydan can know in real time the power demanded (or the energy generated by solar energy) and use it to its advantage. This means that it can balance the power of the e-Charger with surplus power from the house or from the photovoltaic system.

Up to six current clamps can be used for these measurements in the case of three-phase installations, three clamps for the measurement of the general consumption and another three for the consumption of solar energy.

IMPORTANT NOTE: In installations with a new supply, where the charger is the only device connected to the new meter, it is not necessary to configure or activate the dynamic power control unless there are different contracted powers.

In what ways can dynamic power balancing be performed with Trydan?

V2C ControlBox

The V2C ControlBox is handy, easy and intuitive and without complex installations.

With just one device, it offers a reading of up to six channels, allowing measurements in normal installations, with photovoltaics and in both single-phase and three-phase.

The Trydan charger includes a meter (V2C ControlBox), as well as a clamp to clamp the general supply of the house (consumption of the house + electric vehicle). A second clamp is required for photovoltaic installations.

There is an earlier version, V2C 1.0, which is currently not commercially available although it is possible to find it in some installations.

WiFi meters

The Trydan e-Charger can also be connected via WiFi or wired energy meters. Among the WiFi meters you can use the well-known energy meters Shelly and Wibeee.

This is an alternative if it is not possible to run the Ethernet cable from the e-Charger to the V2C ControlBox. It can also be used when the inverter is connected to a secondary switchboard (or the charger is connected directly to the meter) and it is not possible to measure its production.

The WiFi meter and the charger must be connected to the same WiFi signal. This type of meter has the particularity of allowing the correct operation of the dynamic power control in normal installations with two clamps (general + photovoltaic) and in adaptations (inverter connected to a secondary panel) with only one clamp (general). This is possible because it is able to measure the direction of the current and, therefore, all the PV load modes offered by Trydan can be used thanks to the bidirectionality of its reading. In this case it will not be possible to see the solar generation in the V2C Cloud application.

Other compatible meters

As for the wired meters, these include Carlo Gavazzi, Chint, Eastron, or Phoenix Contact, among others. Similar to WiFi meters, these meters do not allow viewing solar generation on V2C Cloud. Nevertheless, all operational modes will function correctly.

These meters will be used when installation cannot be done with the V2C ControlBox (due to the inverter being connected in a different panel to the charger) and when WiFi signal or connection is also unavailable (in this scenario, a WiFi meter can be used).

Direct connection with the inverter

Another way to carry out measurements is through a direct connection with the inverter. Thanks to the advancements and continuous development of the e-Charger, it is possible to establish this type of connection via WiFi, Ethernet, or through RS485 connection with some of the most demanded inverters in the market. Among these are Huawei (with necessary SDongle), Kostal (Piko, KSEM, Plenticore), Goodwe, Solis, Greenheiss, SAJ, Fronius, Victron, SolarEdge, Ingeteam, etc.

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

Through the MQTT protocol

In addition, measurements can be carried out using the MQTT protocol, which facilitates efficient communication between the e-Charger and the other devices, enabling precise and agile control of the electric vehicle charging process.

Installation of dynamic power control

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

One of the common situations an installer may encounter is as follows: in this scenario, the amperometric clamp connected to jack 1 of the meter needs to clamp onto the cable of the main supply line (upstream, i.e., before it reaches and above the main panel – including the general supply line and the charger). Simultaneously, the clamp connected to jack 4 should attach to the cable of the photovoltaic production.

In this situation, the photovoltaic installation is not injecting into the charger panel, preventing the use of the clamp to measure solar energy due to the distance. This impedes the proper functioning of the V2C ControlBox. It is advisable to carry out the adaptation as shown in the diagram, shifting the injection of solar energy from the secondary panel to the main panel to facilitate accurate measurements.

How to carry out the installation of the V2C ControlBox?

NOTE: If the e-Charger and the inverter are not connected to the main distribution board of the house, it is necessary to carry out a prior adaptation of the installation as reflected in the corresponding diagram (green line).

Connect the meter to the e-Charger control board using an 8-wire data cable, crimped in parallel with an RJ-45 connector at both ends. V2C meters do not require their own power supply and feature an LED to verify correct connection. Both the meter and the e-Charger have their own RJ-45 inputs.

The device is not susceptible to interference when the communication cable runs alongside the electrical wiring of the installation, but it is recommended to use Category 6 cable for optimal performance. To connect the UTP communication cable from the e-Charger to the V2C ControlBox, it is necessary to follow the 568A or 568B direct connection standard for crimping the RJ-45 connector.

For single-phase installations, the toroidal (clamp) should read the total consumption of the house, including the charging point. If the installation is single-phase, the toroidal should be installed at the point where the household’s main supply enters, or alternatively, in communal garages on the cable coming from the meter. It’s necessary to locate the phase that powers the entire installation. Usually, it is the feed from the meter and will be colored grey, black, or brown. Once identified, the amperometric clamp should be connected, and the clip closed securely around the cable.

IMPORTANT: The sensor must cover the TOTAL phase to read the energy of the entire installation (house + e-Charger). The cable of the amperometric clamps must not be tampered with under any circumstances and should always be positioned in the direction of the current flow (pointing towards the main distribution board of the house) in photovoltaic installations.

Important: The V2C logo of the e-Charger will flash red in case of a communication error. The most likely cause lies in the network cable (the problem may be caused by a bad crimping of the Ethernet cable connector). In this case, please re-crimp, reconnect and check the cable. It is necessary to remember that this network cable will not pass through the Internet, but data and information to Trydan.

This scheme should be followed when an Ethernet cable cannot be run from the meter to the charger, so communication between the device and the e-Charger will be done wirelessly.

In this situation, the photovoltaic installation is not injecting into the charger panel, which prevents the use of the clamp to measure the solar energy, due to the distance at which it is located, making it impossible for the V2C 2.0 meter to work correctly. In these cases it is advisable to use a WiFi meter (e.g. Shelly) as shown in the diagram. This type of bi-directional meter allows us to measure the energy consumed in the home and that which we export to the grid with a single clamp, it will not allow us to know the photovoltaic production but all the charging modes will work correctly. It is important that the Shelly meter and the charger are connected to the same WiFi network as the user (not the one generated by the charger itself).

The slaves do not require their own power supply and have an LED to verify the correct connection. Both the slave and the e-Charger have their own RJ-45 inputs.

The device does not suffer interference when the communication cable is next to the power cable of the installation, but it is recommended to use Category 6 cable for optimal performance.To connect the UTP communication cable from the e-Charger to the V2C 2.0 slave it is necessary to follow the direct connection standard 568A or 568B for the crimping of the RJ-45 connector.

Locate the phases that supply the whole installation, normally these are the connections coming from the meter and will be grey, black or brown in colour. Connect the current clamps and close the clip to hold them firmly to the cable. In a three-phase installation, all 3 clamps must be used (see slave diagram) and all previously exposed cables must be clamped.

IMPORTANT: the sensor must cover the ENTIRE phase to read the energy of the entire installation (home + e-Charger).

How to install a new dedicated supply with V2C ControlBox?

Steps to follow for configuration and activation

Once the corresponding meter has been installed, the dynamic power control must be optimally configured. Without this step, the e-Charger will not automatically and dynamically allocate surplus energy from the household to the charging of the electric vehicle.

This configuration can be carried out via Bluetooth or WiFi (if available) and accessed from the V2C Cloud application or from www.v2c.cloud on the computer, with the user credentials and password. In both cases, follow the instructions shown in the image.

Once configured, go back to the e-Charger configuration screen to access ‘configure dynamic control’ to customise it.

The installation of the meter must be carried out by a professional. The default V2C ControlBox shall be used if a different one is not available. Various meter versions are available, some of which allow direct integration with PV inverters. Therefore, it is crucial to select the appropriate meter or inverter, considering the type of existing installation, and to save the configuration.

How to customise dynamic power control?

Users of charging points that have the dynamic power control function activated can customise it via the V2C Cloud app or via the portal www.v2c.cloud. Select the e-Charger and access its configuration.

Slide to determine the interval between the minimum and maximum intensity between which the load will oscillate (between the maximum value of the range and the value of the contracted power, whichever is lower will always prevail).

Access the ‘configure load profile’ section to plan different customisations of the dynamic control according to the energy modes and time periods. You can configure the selection of the power tranches by hours, as well as differentiate between weekends and weekdays.

It is possible to carry out the configuration via Bluetooth or WiFi (if this connection is available).

The personalisation of the power configuration can only be carried out if the dynamic control is previously activated correctly.

* When selecting, editing or deleting a personalisation, press the save button to ensure that all changes are saved correctly.
** It is essential to fill in the time slots completely, 24 hours a day without gaps, as well as from Monday to Friday, and on weekends. If this is not the case, it is not possible to save the personalisation.

ENERGY MANAGEMENT MODES

Trydan incorporates the most advanced photovoltaic integration system on the market. It has been meticulously designed to make the most of the energy produced by the solar panels. Therefore, for installations with photovoltaic generation, several energy management modes have been devised in the dynamic control:

Exclusive PV

In the Solar Exclusive Mode, the Trydan charger focuses on maximising the use of solar energy to reduce consumption from the conventional electricity grid. This mode aims to achieve a household’s energy consumption from the grid equal to 0 kW whenever sufficient solar energy is available or, alternatively, to utilise the surplus.
When the household’s solar energy production exceeds the household’s demand, for example, if 3 kW is being generated but only 1 kW is being used, Trydan intelligently adjusts the power distribution. If you plug in your car at that time, the Trydan charger will seek to modify the solar export to be equal to 0 kW. This means that the additional 2 kW will be directed to charge the electric car instead of being sent to the grid.
However, the Solar Exclusive Mode is also aware of fluctuations in solar output. For example, at night or on cloudy days, solar power generation may drop to 1.2 kW or less. In such cases, if the energy demand in the household continues, Trydan will stop charging the electric car. This ensures that the electrical resources needed to keep the home running optimally are not depleted.

Contracted power

Car consumption (always prioritising housing)

Photovoltaic generation

Load stop

PV + Minimum power

In Grid + PV Minimum Mode, Trydan seeks to maximise surplus without sacrificing load continuity. Unlike PV-only mode, where Trydan could cut off charging if there is insufficient solar power, with this configuration a minimum charging threshold is maintained, usually set by the customer via the V2C Cloud app or www.v2c.cloud, which can range from 6 to 15 amps (1.3 – 3.4 kW). This value ensures that the car always charges at least at minimum power.
The advantages of this mode over the previous one are continuity in charging and being able to make the most of surpluses by supplementing them with a minimum consumption from the grid up to a configurable 1.3 kW (minimum charging power).
During the night, when solar production is null, Trydan will maintain a minimum load by means of the supplier’s energy, guaranteeing continuity even in conditions of low solar production.
*In photovoltaic installations with a battery, if the objective is to avoid discharging the battery, the inverter must be configured to limit the discharge of the battery.

Contracted power

Car consumption (always prioritising housing)

Photovoltaic generation

Grid + Photovoltaic (Maximum charging speed)

This mode is set to charge at the maximum power contracted with the energy provider, in addition to the available solar production. For example, if the contracted capacity is 5 kW and the current PV production is 1.2 kW, Trydan will charge at 6.2 kW whenever possible, i.e. as long as neither the household consumption nor the solar production changes.
If the grid consumption exceeds the power contracted with the distributor, Trydan will cut the vehicle charging until the consumption of the house decreases or the solar production increases. In this way, we will avoid exceeding the contracted power.

Contracted power

Car consumption (always prioritising housing)

Photovoltaic generation

No load

It allows users to have full control over the charging process of their electric vehicle. Instead of charging automatically, this mode provides the ability to schedule interruptions according to preferences and needs.
The distinguishing feature of this mode is that you can schedule specific time slots in which you do not want electric vehicle charging to take place. This is useful, for example, to avoid using the grid during peak hours of electricity demand.

Non-injected or isolated

In the case of off-grid installations, the e-Charger does not have access to a traditional electricity meter or to parameters such as the contracted power. Instead, an inverter is used which measures the instantaneous consumption of the house and generates the energy corresponding to what the house consumes at that moment. Batteries also play a key role by storing surplus solar energy during the day for use at night.
The main objective in this context is to prioritise charging the electric vehicle with solar energy, without using the energy stored in the batteries, whenever possible.
In this environment Trydan requires a direct connection to an inverter that allows the instantaneous power reading of the batteries to obtain information about the available energy and charging conditions. In this way, it will be possible to dynamically adjust the charging of the electric car according to the consumption of the house and the energy available at that moment.
If the house starts consuming more energy, the e-Charger reduces the car’s charge to avoid discharging the house battery. Conversely, if the house consumes less energy, it increases the car’s charge.

Customise dynamic power control

How to customise the refresh rate of the dynamic power control?

Possible connection errors

If an error occurs when activating the dynamic power control at the Trydan charging point, a code corresponding to the error will appear on the charger’s display (Indications available as of version 1.6.18.).
The solutions to the errors listed below apply to version 1.6.18 or higher. If you have a lower version, please update the charger and check the list below again.

IMPORTANT NOTE: These errors are caused by a communication fault between Trydan and the inverter or meter and limit your vehicle’s load to a minimum. It is essential to consult the solution to the error that appears on the display. If the error persists, please inform our Support department and deactivate the dynamic charge control to be able to charge at the set fixed current.
