Re: 3.3KW Regrets?

Fri Oct 20, 2017 3:45 pm

I've got the 6kW charger on my Leaf and a 3.3kW on my Volt as well as a 7.2 kW capable EVSE at home. I was able to get 3 3.3kW EVSE's installed at work.

With a commute where I use slightly over half the charge getting either to or from work, and another half charge if I go to lunch, the 3.3 kW work EVSE barely has time to recharge adequately to 75% State of Charge before going home. I wish I had and will probably get at least one of our work EVSE's upgraded to a 40A model. The difference is very noticeable with my trip length.

Otherwise I really notice the fact that my Volt and Leaf take the same amount of time to charge at home from empty, although the Volt only has half the usable charge compared to the Leaf.

If you regularly make trips over 30 miles one way, you won't regret getting the more capable 6kW charge package.

I though about upgraded charger, and....
a) it wouldn't be easy for me to get 6.6kW power when I need it the most (at daytime with home appliances active)
b) I almost always charge to 80% and only charge to 100% as soon as I plan on departure for longer trip or it is cold outside (sub freezing, -10C). But battery won't accept that charge rate anyway at that SOC
c) I definitely use DC charge whenever I need to go further/faster. Luckily I have DC stations all around
d) it's pointless during trips. I always use DC stations when travelling. If I stay overnight, I don't need it.

During 3 years, faster on-board charger would help significantly on average only once-twice a month and usually between October - March. Due to not having that investment I had to use extra 20-30€ of money on DC sessions. During 3 years.
Therefore I'm very happy I didn't take it.

If Leaf doesn't have DC charge capability (very bad) or there is and never will be DC station near home or there is no backup vehicle, then upgraded charger might be more helpful.

^^^
The above is moot on '13+ US Leafs. In the US, starting with '13, if the car comes with CHAdeMO, it will have the 6.6 kW OBC. 3.x kW OBC car with CHAdeMO inlet is not a valid combination on '13+ US Leafs.

On '11 and '12, that wasn't the case but back then, the 6.6 kW OBC didn't exist.

For me, 6.6 kW OBC helps 5 to 7 days of the week. I have not had a car with CHAdeMO since July 2015. On my 2 year leased '13 with CHAdeMO, I used that inlet 16 times in total on free DC FCs. Those free ones are no longer free. Very few are free anymore and the rest are more costly to use to fuel my Leaf than it is to fuel my Prius.

The most common EVSE is a 30A unit. That is more than enough for the Leaf. I 40A EVSE will work fine but the car will only take 27.5A. It will ignore the rest. Currently only Tesla and Tesla based cars draw more than 30A. A volt would only draw 14A @240VAC. The car's charger sets the current as long as the EVSE will supply enough current. An enhanced Leaf needs an EVSE that will supply 27.5A. More is simply ignored.

Thanks for all the replies. I bought the car yesterday and I love it. LeafSpy says the SOH is 86%... so when does it drop to 11 bars, prolly soon?

I took her out for a "first free L2 charge" last night and it charged faster than I expected. It was initially something like 60% charged. I checked two hours later, it was at 99%, then 100% after I removed the cable! Had to drive around for a while to get back down to 80%.

So after all this, what model(max charging current) did you get?
I'm guessing a 6.6kw model but starting out at 60% even a 3.3kw Leaf may be able to get close to 100% after 2hrs, I figure ~20%/hr @ 3.3kw and 30%/hr @ 6.6kw but charging slows down near 100%. Where the 6.6kw charger really comes in handy is SOC in the middle where it really screams or can take the full advantage of a 30a EVSE.

It's the 2014 S with the 3.3kw OBC mentioned in my OP, that's why I was surprised how fast it charged. Maybe I didn't notice the original level correctly. I'll note charge times & levels more closely from now on.

I'm not going to miss my PT Snoozer's 15/25 MPG.

Congratulations! I only have issues with the 3.3 when I drive further than the range of the car. To get back home, If there are no DCQC avail, I'm stuck charging up to 7 hours vs 3.5 with the 6.6.

So it doesn't have a quick charge port, right? Charge speed is technically 3.8 KW 240 volts/16 amps
