[FEATURE REQUEST] Could "State of Charge" display negative Values?

[HaareistNase]

I do calculate "real" usable remaining kWh for my SOC, so that I can spare the "there is 20% Minsoc, how many kWh can I use until the battery runs dry".
I love to have this number in the Soc-Field for battery, what is no great Problem. Works coool.

But I have one concern. If I push my MinSoc on a Number above the actuall SOC ... the usable kWhs get negative.
My sensor is working great and computes the negative value (kWh needed until the battery is charged enough), but the SOC-Display does not show negative values.

I think this is a minor change, but I can't do this on my own. So maybe you can help me pls.

Regards
Alex
