MQTT kWh Battery measurement messages for a Battery - But HA doesn't accept it for a device_class = battery

[yoba-ch]

The problem

Hello,
I've a MQTT message from my Huawei Inverter as of "[Energy storage unit1] Current-day charge capacity" in kWh.

Should I use something else as a device_class or is it possible to have this implemented in Core HA?

Thank you.
Alex.
