I would be running a conduit run for future use of EV charging stations. In my opinion, EV‘s are fairly new technology, that the NEC has not been able to fully address with the current code requirements. For example, there has been no consideration for increasing the circuit for rapid charging of EV’s, and the new Ford version of an EV pickup will require a minimum of 80 amps for charging. This technology is still evolving, and at this time there are far too many unknowns to be able to make any kind of “educated guess” for sizing future EV charging installations.
