If you aren't having your factory EVSE upgraded right now, and you are just going to try L1 charging for now, you don't need 240 VAC. But, if you have the electrician there to do the work, I would have him prewire everything for both 120 VAC and 240 VAC. My garage has a subpanel box, with BOTH a 20 AMP 120 VAC outlet and an L6 240 VAC outlet. The 240 needs 2 hot legs and ground. The 120 needs a hot leg, neutral, and ground.
If you don't think you will go the EVSE Upgrade path, skip the L6 240 outlet, as most L2 EVSE's need to be hardwired in.
