Aivar, congratulations on your purchase and welcome to the forum. In addition to the above responses, might I add -
Aivar wrote:...My workplace is looking into putting up a plug for me to charge with Level 1. So that would give me enough juice to make it back home with some extra miles for errands. I suggested dedicated 20 amp GCFI plug. Any thoughts?
Sure, 120vac over a workday will easily fully recharge your car for the drive home, although the only time you might really need it is in the dead of winter.
Aivar wrote:My i-Miev comes with Level1 charger but I would like to install Level2 also in my house?
Before you buy, you might consider making that L2 EVSE removable so you can take it with you whenever you go on a long trip and might need to charge on the road - for example, whenever I visit distant friends I plug into their dryer outlets in their garage. Wire your house for a 14-50 outlet, install a 14-50 plug on the EVSE, and make a few adapters. That 14-50 outlet will allow for your next higher-power electric car.
Aivar wrote:What type of extension cords do you have for unplanned charging on the road?
Reality is that you should never have unplanned charging on the road, unless you venture out on a long trip. A 50' #12AWG (or #10AWG) extension for your existing Mitsu EVSE will be fine, but you will probably never use it as you will usually try to find 240vac outlets.
Aivar wrote:Nearest EV charging for me is for Teslas. Is there a way to hook up iMiev to it?
Nothing for Tesla's DC chargers, and there is at least one adapter out there for Tesla's 240vac HPWC, but it's too expensive.
Aivar wrote:What do you think about getting OBDLink LX and CaniOn and EVBatteryMon? Is there solution out for iPhones?
I consider those apps very nice but most people can live without them. For me it was worth getting an Android tablet just to use them. EVBatMon has an iPhone version.
Have fun, and practice getting a feel for the exact distances you normally drive in your surroundings and how much 'fuel' is required - you'll quickly understand your limits. For my lifestyle of around 1000 miles/month, I almost never fully charge the i-MiEV, rarely come home with fewer than two bars, and have never seen turtle.
