Understanding brief view as an overview which should be easy to look over with a short view maybe even for laypeople.
For this in my opinion the units A and V underneath the battery SoC are no good choice.
Everybody knows the meaning of W and all other values are displayed in W. So the battery power should be displayed in W at brief view too.
Only experts know the meaning of V and A related to the battery.
The only application where A maybe usual could be campervans and boats where the users are used to deal with their consumption in A because they know their battery capacity in Ah.
So to make it ok for everybody it would be the best to make it configurable.
