I'm going to have a level 2 charger installed in my carport to charge my Honda clarity PHEV. Southern California Edison has 2 options. 1. use a time of use [TOU] plan for the whole house 2. have a separate meter installed to charge the EV with a special TOU plan. rest of house remains on the original meter. Appreciate any thoughts of the pros and cons of each approach. Since the carport is on the opposite corner of the house from the main electrical panel, my electrician needs to set up a separate subpanel to install the level 2 charger, so I will have to have some electrical work anyway.
