You may have questions, we certainly have answers.
Many questions have been asked of us before. We have listed the answers.
With the Ratio EV Charging app, you have full control over your charger. For example, you can also find the charging history here.
To add a charger to the Ratio EV Charging app, the charger must be connected to the internet, the mobile phone must be connected to the internet, and Bluetooth must be enabled on the smartphone. Then, create an account in the Ratio App. After you have logged in, click on 'My charging stations' and then at the bottom on 'add a charging station'. The app will now search via Bluetooth for a charger nearby, and your charger will appear on the screen. With the Bluetooth code provided with the charger, you can connect to the charger.
The Ratio App works with the following Ratio models: Smart, Solar, and io6.
Ratio's online models (Smart, Solar, and io6) support over-the-air updates. Ratio recommends installing available firmware updates as soon as possible. Firmware updates keep the charger's data security up to date and regularly add new features. Updates are performed sequentially, so it may be that the system offers multiple updates in succession. Please refer to the release notes on the Ratio website or in the AppStores for more information on new features and system improvements.
When a firmware update is available, the update icon will appear next to the charger in the "My chargers" screen.
1. Tap on the charger's button to install the update.
2. Tap on "Install Now" to install the update immediately or tap on "Install Later" to postpone the update to allow charging your car immediately.
The update notification will appear the next time you open the "My chargers" screen.
Note: Ensure that the charger remains powered during the update and is connected to the internet. Power/network interruptions can cause the update to fail.
The Ratio EV Charging App does not need to remain open during the update.
While the update is in progress, the icon will be displayed next to the charger in the "My chargers" screen. Please note that the update may take several minutes. After the update, the charger will restart and be ready for use.
NOTE: Do not use the charger during the update process.
3. After updating the charger's firmware, check in the AppStore or PlayStore if an update is available for the Ratio EV Charging App and update it if available. Regularly check for updates in the "My chargers" screen of the Ratio EV Charging App.
Note: Using an old version of the Ratio EV Charging app may lead to compatibility issues.
After enabling Scheduled Charging and setting the desired schedule, you don't need to press start; charging begins automatically at the set time. However, the Start button can still be used to initiate a charging session immediately.

In the Ratio EV Charging app, go to 'Settings', then 'Advanced Settings'. Make sure the charger is connected via Bluetooth.
Select 'OCPP settings' at the bottom of the screen.
Turn on the OCPP selector and then choose 'E-Flux' as the Open Charge Point Provider. You will now see your Charge Point ID, which you can easily copy to your clipboard.
The Charge Point ID has the format 'RATIO_Pxxxxxxxxxxxxxx'. Use the Charge Point ID to register the charger on the E-Flux portal.
Create an account with E-Flux for an AC Charging Station. Go to https://e-flux.io/nl/tarieven/ and follow the steps to create an account and enter the Charge Point ID (CPID). You can use the information from the clipboard or manually enter the CPID.
After activating OCPP, simply use an RFID charging card to start a charging session. The RFID symbol on the 'Charger Overview' screen is gray when no card is read and green when a card is successfully read.
All functions of the Ratio EV Charging app, such as Scheduled Charging and Smart/Solar modes, remain available when using OCPP.
Error 111 indicates that the charger cannot communicate with the sensor box. An installer can check if the wiring between the charger and the sensor box is properly connected.
The Sensor box is the black box placed in the meter cupboard. With correct connection, the LED on the sensor box flashes three times, followed by a brief pause. This indicates the flow of electricity, per phase. Green means there is an excess of solar power, while red indicates energy is coming from the grid. For example, if the solar panel installation is connected to phase 1, the LEDs would be: green – red – red.
The sensor box receives power from the mainboard, and the LED will be red. In Smart and Solar modes, the LED will flash three times with a pause. If no solar energy is being generated, they will flash red. For instance, if energy is being generated on phase 1, the LED will flash as follows: green, red, red.
Basic: The charger charges at the set maximum charging power in the app settings. Note: Dynamic Load Balancing is not used in this mode. If the sensor box is installed, this mode cannot be chosen.
Smart: Charging with Dynamic Load Balancing. The charging station protects your home from overload while charging the car at maximum speed. The charging speed is adjusted based on other electricity consumption in the home or office. This allows you to charge worry-free and as quickly as possible. The charger charges when the available power is higher than the minimum set current in Amps (Minimum Charging Current) and below the maximum power still available on the connection.
SmartSolar: The charger charges using a combination of solar power and grid power, unless there is enough solar power available. If the minimum current is set to, for example, 6A and there is 4A of solar power available, the charger will supplement this with 2A of grid power in SmartSolar mode. If there is a surplus of 6A or more from the solar panels, the charger will only charge using solar power. This way, you can benefit more from your solar power while the car charges slowly but steadily.
PureSolar: The charger charges using solar power from the minimum value, usually 6A. If there is a surplus of 6A or more solar power, charging will commence. If the sun is absent for an extended period, charging will pause until there is enough surplus solar power available again.
For these functionalities, you need the Ratio Sense kit, which is available for separate purchase.
The charging station protects your home or office from overcharging while the car charges at maximum speed. The charging speed is adjusted to the remaining consumption in your home or office. So you can always charge as fast as possible without worries.
Yes, typically, with a 3-phase PV installation and a 3-phase electric vehicle, you would need 6A per phase to start charging. This means that in the PureSolar mode, you can only start charging with an excess of 4.2 kW of solar power. However, we have a solution for this: In the Ratio App, under 'advanced settings', you can change PV charging to 1 phase. By doing so, even if you have a 3-phase PV installation, you can start charging from as low as 1.4 kW in the PureSolar mode. This way, you can benefit much more from charging on solar power throughout the day.
In the Ratio App, you can go to advanced settings and click on 'measured values'. Do you see positive values under Currents at the Sensor box for a particular phase? In this phase, power is being used from the grid. Is the value negative? In this phase, there is an excess of solar power. With an excess of solar power and a 3-phase solar panel installation, you would see 3 negative values in the App.
If the car is unlocked, you can follow these steps in the Ratio App:
Open the app, go to settings, then cable lock, and while slightly pushing the plug into the charger, change the setting to "Always locked", then change it back to "Car unlocks". It is important to keep the cable pressed in during this entire process; the cable should now be able to be removed from the charger.
Do you see installation values that you don't expect? Contact your installer.
Yes, all Ratio chargers that are standardly equipped with 3-phase (22kW) capability also work with cars that can charge on 1 phase. Additionally, the charger can be installed using only 1 phase.
Yes, Renault vehicles can be charged by Ratio chargers. Note: Vehicles that are Renault ZE-Ready can only be charged in Basic mode.
Yes, our latest Ratio Solar models and all Ratio io6 chargers are suitable for charging on Dynamic energy rates. This way, the charger can be controlled with smart software and start charging at the best/cheapest times. We do this charging on dynamic rates via a free link with Tap Electric. You can link your Ratio charging station via 'OCPP settings' with Tap. Then create an account in the Tap Electric app and link your Ratio charger here. In the Tap app, you can then set the settings for charging at dynamic rates based on your preferences. For more information, see:
