Clear the cache on a charger

POST 
/chargers/:id/actions/clear-cache

Sends an OCPP ClearCache command to clear the charger's local authorization cache.

Use Cases:

  • Remove revoked or expired ID tags from charger memory
  • Force chargers to re-fetch authorization lists from the central system
  • Clear stale authorization data after policy changes
  • Troubleshoot authorization issues (stale cache)
  • Implement security compliance (immediate credential revocation)

What Gets Cleared:

  • Local authorization cache (ID tags, users, permissions)
  • Offline authorization white/blacklists (if cached)
  • Authorization transaction log cache (depends on vendor)

What Remains:

  • Charging profiles and schedules
  • Configuration parameters
  • Firmware and boot settings
  • Active session data

Best Practices:

  • Use after revoking ID tags to ensure immediate effect
  • Send after bulk authorization updates for consistency
  • Coordinate with SendLocalList for authorization management
  • May cause brief authorization delays as cache rebuilds
