Since we already support providing the capacity at different
temperatures using ocv-capacity-celsius and the array of
arrays ocv-capacity-table-0, 1, 2... you are introducing a
second parallel method of describing how capacity changes
in accordance with temperature, right?

What do you expect to happen if someone specifies both?

If this is an either/or situation then the schema has to
guarantee the exclusiveness for each.

(I would probably just use the formula you have to calculate
a few tables using the existing method but that's just me.)
