    Default Lack of 6.6kw charger b/c of cost, battery stress or something else?

    Has GM publicly said why they didn't include a 6.6kw charger instead of the 3.3kw one?

    Was/is it to keep costs down? Is it less stress on the battery?

    It was designed in 2006-2007. I suspect that had something to do with it. Plus, it's adequate for the charging time (4 hours). Not sure about stressing the battery, but the battery is being babied as much as possible and I think that's a good thing.

    Pamela Fletcher described the HV battery as the most pampered automotive component every produced. My guess is that is one factor and the other was simply safety outside of the car in the garage. Less current. The difference in cost is probably a a throw away. What is also striking is GM''s decision to significantly reduce range to protect the battery.

    One of the most comments I hear as a Volt driver, is aren't you worried about the battery giving out. Although my sample size is very small, its clearly a reason many use to dismiss EV's. The lifespan of 12 volt automotive batteries is well known. My response that there is little or no evidence of battery issues with the Volt is usually greeted with a raised eyebrow.

    My guess is GM is saving that feature for 2014 Cadillac ELR.

    That might have been a Fox News/Limbaugh inspired notion. I don't know if your own experiences validate this, but in my experience, most people forget where they hear many of the beliefs they hold to be true.

    I don't know about any official statements by GM on the topic, but it's probably a little of both.

    Moreover, a fast charger just isn't that important on an EREV. On a BEV where you might need to wait for your car to finish charging before starting your next trip, a fast charger can be very valuable. But with an EREV it's just not that big of a deal.

    When they first rolled out the Volt forum at the GM web site they were quite clear that it was out of concern that it would stress the battery. I hope the next generation of Volt is able to use 6.6 kW and DC charging. Personally if forced to choose I'd go with the DC charging. Unless you have something to do two hours is too long.

    One big benefit of 6.6 kW charging is that it would cut the cost of charging at public chargers.

    3.3 kW is fine for overnight charging, but I want a 6.6 kW for this reason. $2/hr charging stations are like buying gas at $8/gal. With a 6.6 kW charger the same charging station would be equivelent to $4/gal, and I could get a full charge in 2 hour stop.

    I think the 3.3Kw charger in the Volt is plenty. Half of Volt users are charging from 120V anyway. I imagine 5% of Volt owners would benefit from a faster charger. It just isn't worth the extra cost.

    I think it would be much more beneficial for an all-electric vehicle, however.

    While I would love a 6.6kWh charger (it would be the first option I would check when buying a new one). Remember even the $100k+ Fisker Karma only has a 3.3kWh charger. I think it is symptomatic of when it was designed and possibly cost. Most new PEVs will have 6.6, it's just a matter of time.
