Electric Vehicle (EV)

For the EV agent to run as expected, all dependent components must meet the agent's minimum supported versions, as described below. When the agent is installed and running correctly, there are certain messaging expectations you can rely on for assistance in installation and troubleshooting. Those expectations are described in this section as well.

The following table describes the minimum supported versions for the agent's component dependencies.
