Not at all. EV's are extremely common in Yosemite. There are no chargers in the park itself (as far as I know) so you'll need to plan properly, but there are several along the route to the park.

Just avoid using autopilot, unless you like driving into rocks... Also as kxc262 pointed out, be sure to check the conditions in advance - the main route into the park from SF is currently closed likely until at least early July due to damage to the road (there's an alternate route so it's easy enough to avoid).
