This is not just about charging data, but also about the batteries
thermal limits, technology and full capacity, so how about

struct psy_battery_information {

char *name;

No need for arbitrary length limitation.

Please be more verbose about the information being stored here.

No need to embed this into the struct. Just point to the array and
remove the size limitation.
