One of the interesting things in the ISO 15118-2 (and ISO 15118-20) protocols for EV charging, is that they include a check for "is your contract certificate expiring soon?".

So yeah, certificate timelines can be monitored, completely with warnings ahead of time.

Corollary : the service checking the certificates should have a reasonably accurate time.

This could be a part of your CI/CD. Warn when cert lifetime is below threshold.
