Three years ago, I installed a 240 volt dryer outlet (with 40 amp service) at the head of my driveway, so my brother-in-law could charge his Tesla when he came to visit. Now I may buy a Chevy Bolt. It appears, however, that to home charge the new beast, I will also need to buy an EVSE (hate the acronyms and the jargon) for another $500 bucks - plus installation costs. Do I really need a new Electric Vehicle Service Equipment (read charger)? Why can't the Bolt charge with a simple cable from wall to car - just like the Tesla?
