Disabling battery charge and discharge

[Fardenco]

I have an electric car charger which is able to adapt its power to my pv excess power.
The problem is that when the car is charging, the regulation system of the charger fights with the regulation system of the battery and often the battery ends up discharging to the car.
I'd like to simply tell the battery not to charge or discharge when the car is charging, but I can't find a way to do this.
Do you have any suggestions ?
Thanks !

I opened this discussion because I could not find the charge and discharge power limit settings in Home Assistant.
This screenshot showed them on the battery device : https://github.com/wlcrs/huawei_solar/blob/main/images/battery_configuration.png
But my battery device does not have those entities.
I have now found them, it seems like they were moved from the battery device to the inverter device.
Setting them to 0 does exactly what I need.
Have a nice day
