Simplicity is key.
One of the pain points for many EV owners is the installation of their home charging station (EVSE). A quick search of some of the online electric vehicle forums and Facebook EV groups will uncover many threads with the poster asking for recommended installers and how much they should expect to pay.
For some reason, it occasionally seems that some electrical contractors charge more to install an EVSE than they would for a similar device with the same power requirement. It’s not often that homeowners need a dedicated 40-amp or 80-amp circuit added to their garage. So, without any previous experience to compare the quote to, it’s natural to be concerned about possibly being overcharged.
