-
Software updates require the charger to be connected to the internet. Once connected, available updates can be viewed in the app.
-
Clean the charger by wiping it with a cloth dampened with water. Avoid using a high-pressure cleaner or exposing the charger to running water to prevent damage.
-
Please contact Amprisen customer service before attempting to disassemble the charger and await their instructions on how to proceed with the service case. For safety reasons, any allegedly defective, stationary installed Amprisen Charger should only be dismantled by a qualified electrician.
-
If you encounter a technical issue with the Amprisen Charger and cannot find a solution in the user manual, FAQ, or troubleshooting guide, please reach out to our technical support team. You can contact us via email, the support form on our website, or by telephone. In many cases, we can resolve issues without the need for repair.

No, the chargers from Amprisen require no maintenance.
-
Adjusting the charging power on the Amprisen Charger is straightforward.
You have two methods:
Option #1: Adjust the charging current directly on the Amprisen Charger by briefly pressing the TFT Screen（If the charger is with TFT screen). Please note, the button can only be used before starting the charging process; it is disabled during charging.
Option #2: Set the charging power using the Amprisen app. Navigate to the "Charging" tab and click on this symbol. Here, you can adjust the charging power as needed, even in 1-ampere increments using the slider.
-
To export charging data from your Amprisen Charger, open the app and navigate to "Charging Statistics." Here, you can view the charging status, energy consumption, and other details. Tap the "Export" option located in the top right corner to export the charging data as a CSV file. A new window will prompt you to enter your email address. Once entered, a green confirm button will appear. Click "Confirm" to send the CSV file to your email address.

Based on our experience, the charging capacity has a minimal impact on battery aging, particularly when using alternating current. Although various claims exist online, they often refer to outdated battery technology and smaller battery capacities.
A useful metric for understanding charging capacity and its impact on battery health is the C-rate, which represents the ratio between the charging current and battery capacity. For instance, if you charge your car at 22 kW and the battery has a 22 kWh capacity, the C-rate is 1. If the battery capacity is reduced to 11 kWh while the charging current remains 22 kW, the C-rate becomes 2. A higher C-rate indicates a greater impact on battery life due to the charging process, although this effect is significant only with very high mileage. When the C-rate is 1, the reduction in battery life is negligible.

In the app, you can view the electricity charged during each charging session and the total kWh charged. Additionally, charging energy can be displayed for all user accounts. The easiest way is to check it by reading the screen display.
-
You can adjust the charging power either by using the TFT on the device, or via the app. The values can be customized within the app to range from 6 to 16 or 32 amperes, depending on the charger’s maximum capacity (7/11 or 22 kW).
-
The first user acts as the administrator and has the authority to invite others to access the charger. If someone requests access to the charger, the administrator will receive a notification to approve or deny the request.
-
No, your charger doesn't need to be connected to WiFi for basic app functionality. The app can operate through bluetooth. However, features like remote control, flexible electricity tariffs require a WiFi connection.
-
Yes, you can use all the primary functions of the Amprisen Charger, such as starting/stopping charging and adjusting the charging current, without the Amprisen Charger app. However, to modify basic device settings, utilize comfort functions, read the internal electricity meter, or control the charger remotely, you will need the Amprisen Charger app. You can manage the device up close via its built-in access point. For remote control capabilities, you must connect the charger to your WiFi network.
-
The charging process automatically stops when the car's batteries are fully charged or when an event defined in the app occurs. You can also manually stop charging either through the app ("Charging" tab) or by unplugging the charging cable from the vehicle side.
-
You can adjust this setting through the app, ensuring that the charging process will only commence once you unlock the charger using either the app or an RFID chip.
-
Once the Amprisen Charger is installed by an electrician, you can immediately start using it. Simply plug the type 2 cable into both the car and the charger, and charging will begin automatically with the default settings (Plug and Play). If you disable the Plug and Play mode, you have two additional methods to start charging: 1. Using an RFID card, or 2. Using the app.
-
The Amprisen Charger is compatible with charging all electric vehicles that have a type 2 plug. Vehicles with type 1 plugs can also be charged using the Amprisen Charger by utilizing a type 1 to type 2 adapter or cable.
-
1. You can adjust the amperage on the Amprisen Charger using the TFT Screen. The charging levels are displayed by screen, so if you need to decrease from 10 amps to 6 amps, for example, simply keep pressing the button until you reach the 6 amps.
2. Alternatively, you can set the charging current via the Amprisen app. Click on the "Current" icon to adjust the amperage. You can change the charging current during the charging process in 1-amp increments using the slider.
-
For the Amprisen Charger with a maximum charging current of 22 kW, you can choose a current setting between 6 A and 32 A. For the Amprisen Charger with a maximum charging current of 11 kW, you can select between 6 A and 16 A. Both versions also allow you to limit the current to a lower level if desired.
To utilize the full 22 kW charging power of the Amprisen Charger, a 32-amp fuse is required. For the 11 kW variant, a 16-amp fuse is necessary.
Note: Higher amperage settings result in faster charging for your vehicle. However, charging at lower amperages is more sustainable and can positively impact battery longevity and power grid stability. The actual charging power may be limited by the vehicle, which means it could be lower than the maximum capability of the charger.

The miniature circuit breaker is a fuse that disconnects the circuit in case of an overload, protecting the line from damage due to excessive current heating. For a maximum current of 32 A, we recommend the following cable cross-sections:
- 6 mm² for surface-mounted cables (not installed in a wall)
- 6-10 mm² for cables in installation pipes
- 10 mm² for cables in thermally insulated walls
For a maximum current of 16 A, we recommend the following cable cross-sections:
- 2.5 mm² for surface-mounted cables
- 4 mm² for cables in installation pipes
- 10 mm² for cables in thermally insulated walls
However, the final decision should be made by an electrician based on the local conditions. The installer must also consider the simultaneity factor when calculating the cable cross-section. The simultaneity factor should be set to 1, meaning the electrician must assume that the cable is always fully loaded.
