Re: EVSE options for 2013 Leaf

Sun May 12, 2013 7:31 am

evnow: When you said "to set the max current draw to 16 amps", did you mean only for those residential Blinks whose owners have a RAV4 or Fit? If so, what about all the public Blinks -- is their approach to recognize a RAV4 or Fit indirectly via the RAV4/Fit owner's Blink Network card and reduce the max amps to 16 for just that charging session?

I always thought that the charging process is complicated enough that because a "problem" can be a result of multiple causes it warrants thorough testing, examination, and analysis before making conclusions.

I hope more information comes out before long -- thanks, evnow, for your efforts to find out and let the rest of us know!

From what I was told this is what they are doing if someone complains - both for public and home charging stations.

Not sure if I should have started a new thread (or searched more thoroughly to see if this was posted already), but I recently upgraded to a 2013 with 6.6kw charger, and I thought my GE Wattstation would be able able to provide full, maximum charging to the car, but it is only drawing 5400 watts. GE spec state 7.2kw output, and I am on a 50 amp circuit. I will be contacting GE to see what the limiting factor is here. Love the 2013--slightly disappointed with the lack of faster charging.

It should be easy for a 2013 Leaf (hi-power) owner to calculate the approximate charging rate (i.e. power) in kW of a Level 2 Blink: Just divide the kWhs delivered during the charging session by the charging time in hours. For a residential Blink, reading from the Main and Stats screens:

Aprox. Power(kW) = ["Stats/Energy(kWh) End" - "Stats/Energy(kWh) Start"] /"Main/Charge Time"

Example: "Stats/Energy(kWh) Start" = 108.07, "Stats/Energy(kWh) End" = 120.39, Main/Charge Time = 03:17 so Aprox. Power(kW) = (120.39 - 108.07) / (3 + (17/60)) = ~3.75

For a public Level 2 Blink, the total charging time is reported to the user, but not the total energy (kWh). An approximate charging rate can be inferred from how fast the estimated range increases. For ~3.3 kW charging, one should expect about 1 mile of additional range for every 5 minutes of charging. For ~ 6 kW charging, one should expect about 25 miles of additional range for every hour of charging. I'm not trying to be real precise here, but to use numbers that are easy to remember -- range after all depends on a lot of factors.

evnow: I talked to a Blink support person just now (about a down public Blink), and at the end of our conversation asked about any Blink overheating problems for the 2013 hi-power Leafs. He said he personally has never received a call from a Leaf owner with such a problem. He did admit that there were a relatively few Blink charging stations that had had such a (isolated manufacturing defect) problem, but my understanding from him was that their policy was to correct them and not to just limit their power.

I understand that he is hardly an independent, unbiased source for information, but can any 2013 Hi-power Leaf owner attest to evidence of low-power Blink charging? Please post if you have...

Apparently their policy changes depending on who you talk to !

I would have expected to see something closer to 6.6kW, which is what the 6.0kW charger draws. What level was your battery at when you checked? The charge current drops as you get closer to full.

Re: EVSE options for 2013 Leaf

I traded in my 2012 LEAF for a 2013, one of the reasons was to get the 6.6 KW charger. I have a GE Wattstation and a EVSE upgrade "brick". I kept the 2012 EVSE and traded in the car with the 2013 EVSE left in the old car. So, for a test I measured the grid power that the new LEAF drew from the line with the various EVSE's. First, with the Wattstation, power input was 6,580 watts which is pretty close to 6.6 KW. I don't think the Wattstation would draw more then 100 watts to operate the contactor and electronics therefore, the charger in the car is seeing close to its rated output. The EVSE upgrade "brick" charged at 3,670 watts on the 240 volt line drawing 15 amps. One the 120 volt line, it charged at 2,124 watts a little over 17 amps. This is Phil's upgrade with the higher power option which makes the upgraded "brick" viable even for new cars with the larger charger. BTW very happy I swapped the leases as there are several changes I really like on the '13.
