In your situation, I would only lease, 2 yrs, and for less than $200/mo. Right now we don't know how long the 40 KWh 2018 battery will last, but if the 30KWh 2017 battery is any indication, you will have difficulties making 70 mi after 2-3 yrs. Unless you're able or willing to charge at work or along the way, be prepared for significant degradation. I hope for Nissan's sake (and EVs in general), but at this point it's "Fool me thrice.....".
I do have 12 chargers at my work to use and I can charge at home. Are you saying charging the battery when 1/2 discharged or so as opposed to waiting until it's closer to fully discharged would degrade the battery slower?
Ron, with the option of charging on both ends, you’re good to go for many years. The “best” charging protocol, in theory, is to charge the least amount to meet your needs, around 50% SOC. For example, for 70 mi RT at about 3.5 mi/KWh, you’ll consume about 20 KWh. Thus, with a 40 KWh battery, you should charge between 10 and 30 KWh. Of, course you’ll want to save some extra for emergencies. This is actually a pretty good choice, as long as the battery doesn’t degrade during your years of commuting. Unfortunately, you should plan on degradation, maybe 5% per year (we don’t know how much the 40 KWh battery will degrade, but in your hot environment it will be worse than others). Can you still make your commute after 40% degradation? 0.6 * 150 mi = 90 mi. So yes, but it could get tight in inclement weather. However, with the possibility of charging at work, you’re golden. I would go for it, drive the ‘ell of it. Charge to 80% as much as you can. You might need to top up at work on bad weather days, but maybe you’ll get 2-3 years out of it without problems. Worst case, Nissan has to give you a new battery under warranty.
