They control the heat input, too. Software fixes:

* limit max current (dumbest) * limit max current based on moving average of current over last N seconds * limit max current based on experimentally validated thermal model of contactors (cleverest)

This might even be possible without a significant/noticeable performance hit, if the overheating is only experienced in extreme conditions.
