Hi Nikwax,
I had the local Bosch representative, an electrician give me a bid to install a Bosch unit. I already have a dryer plug in the garage that I would use for the EV. I'm not eligible for state rebates in FL. With the Bosch unit, the bid was $1800. Sure wish I was kidding. The electrician would not provide a bid without adding on a second 240 plug. Phone calls to Bosch were not answered. Electrician (a nice guy who found a niche) told me he is providing 5 bids a week due to sales of the (in my opinion, underpowered) BMW EV. Good business for him, but not an amount I would spend!
Chargepoint has multiple free public units (libraries, AAA, grocery stores, airport waiting area) around town, as well as pay per units. I not only liked the features and size of the Charegepoint home unit, I appreciate having one vendor to manage. I hope ChargePoint will work with our local electricity provider, TECO, so I can preset a charge during the lowest rates. I'm fine waiting because we are moving in a few months to a new home that does not have the 220 plug in the garage. My (new) electrician gave me a bid of $825 to install the Charge point charger on a separate panel that will support the EV as well as a 30 amp for our RV. So for now, I use the 110 that came with the car. Slow, but does the job.
Best,
Janet
