MCE Sync is currently configured to support only one EV per account. We plan to support more than one EV on the same account in the future. It’s possible to connect more than one EV to your MCE Sync account if both vehicles are connected to the same OEM account (e.g., two Teslas connected to the same Tesla account); however, ev.energy hasn’t fully tested how the MCE Sync app performs with multiple EVs connected to the same account and therefore can’t guarantee its reliability.
