You can show your company logo on the charger screen. The logo can be configured via OCPP and has to meet certain requirements.
How to get the logo on screen:
First, host the logo at a secure server (https://) that the charger can access. Then set the key CustomLogoUrl to that URL. Setting this configuration (CustomLogoUrl) triggers the charger to download the logo and display it on screen.
Image requirements:
The logo must be provided as a PNG file, with a maximum file size of 100 kB. The image may be up to 300 × 300 pixels.
The charger displays the entire image without cropping or distortion. The original aspect ratio is always maintained. If the image is larger than 300 × 300 pixels, it is scaled down proportionally until it fits within a 300 × 300 pixel area.
For example:
- a 600 × 400 px image is scaled to 300 × 200 px.
- a 400 × 600 px image is scaled to 200 × 300 px.
When the image is resized, anti-aliasing is applied to keep the image smooth and clear. Animations are not supported.

Remark: When a valid URL is set, the image at the location is downloaded onto the charger. When an empty string is set, the logo is removed from the charger. If the image is not valid or fails to download, a warning signal "CustomLogoFail" is given.
