Install Certificate

Source: OCPP 2.0.1 Part 2 — Specification (Edition 2, 2022-12-15) — Section 1.30 (Messages); Use Case M05 — Install CA certificate in a Charging Station (Functional Block M. ISO 15118 CertificateManagement)

Overview

The CSMS sends InstallCertificateRequest to install a root/CA certificate (V2G, MO, CSMS, or Manufacturer root) into the Charging Station's trust store.

NOTE (from spec): This message is not for installing a TLS client certificate in the Charging Station. The CertificateSignedRequest mechanism is used for that.
