    charging losses for DC quick charge

    Don't get me wrong. I don't know what efficiency it is. I just mean that it CAN'T be higher than 95% because of at least the heat loss. I would also assume that when the Eaton charger says 'energy dispensed', surely that is what they mean. The energy that entered my car at the plug. That...

    charging losses for DC quick charge

    What are the charging losses for the DC quick charger? I just used one for the first time and it gave me 40% according to the dash and the DC quick charger reported that 8.7 kWh was dispensed. It also raised the temperature from 71F to 81 F (thanks LeafSpy) in those 15 minutes of charging. So...

    Carwings / Data Transmission Agreement

    Is the full legal agreement for Carwings located somewhere? I'm sure the full agreement is much longer than the short statement on the touch screen (that you would need to read quickly if you really wanted to know all the details). I looked around on the webpage and didn't see one there...

    Low cell-pair voltage, CVLI, pack capacity

    This is sort of what the dealer told me. So I did go through quite a few 100% charge cycles with lots of time for balancing. It didn't really change anything. My bad cell is usually the lowest when fully charged by about the amount yours is, but then as it discharges, the bad cell gets out of...

    Low cell-pair voltage, CVLI, pack capacity

    17.5kWh of usable energy is about right for an 80% charge. But the 17kWh I get is measured using a utility grade meter mounted on my wall feeding only my charger which also measures the charging losses which are about 15%. Thus by measuring the 17kWh, I surely have a battery with 15% less...

    Low cell-pair voltage, CVLI, pack capacity

    Driving: I drive about 1000 miles per month. Most trips are 10-20 miles, with lots of dad-taxi service going on. I try to take the flat routes with few stops and average 25-50 mph. Due to the issues with this car, I have done more highway driving just to test the vehicle out. So I've added...

    Cell Voltage Loss Inspection test (cell-pair test), P33E6

    Wow, so just to be sure. If anyone has had their car register this error code, P33E6. PLEASE post your experience and the outcome. Thanks

    Low cell-pair voltage, CVLI, pack capacity

    This is why I take the measurements that I 'quote' only when there is no load, like sitting on the side of the road for a few minutes to make sure LeafSpy has updated a few times. Yesterday, I got the battery down to 317V to check the specs against what the manual states. It says that at 317V...

    Low cell-pair voltage, CVLI, pack capacity

    My cell variation at 20 Gids is around 100-300 mV, much more than you report. The test from the service manual is that the (avg-low) > 2.5 * (high-avg) BUT that this CVLI test is only run when error code P33E6 is reported. My cell variation is well outside the range of Nissan's Specs, but I...

    Low cell-pair voltage, CVLI, pack capacity

    Is this really true? I have a 2013 that Leaf Spy shows ONE module that is low upon discharge, and it is this one module that forces the car to turtle every time. With Leaf Spy, on a full charge, I always start at 284 gids (101% gids), 97% SOC, 22 kWh available, and that module is level with...

    Cell Voltage Loss Inspection test (cell-pair test), P33E6

    In the 2013 repair manual, pages EVB160-EVB164 describe the work to do in the event of error code P33E6 (Cell Controller). Steps 3-5 include the CVLI test which instructs that the minimum cell voltage must be 3,712mV or less for the test to be valid and that the proper condition of the test is...

    Bad Cell Module and balancing issues when braking

    I'm not convinced you have a bad cell since cell-pair 25 is not balanced. The real question is why is your LEAF unable to balance cell-pair 25? Perhaps there is a problem with the shunts... Sometimes at 100% the cell pair IS balanced. Sometimes not. But it always ends up unbalanced by the...

    Removal of factory mud flaps

    It's not that the ice sticks to the flap, it is that the wheel side of the flap is NOT FLAT and SMOOTH. It is actually cupped so that the flap catches the ice and snow on the inside. That is a stupid design IMO. This is only in really cold weather. If the ice is slushy, then yes you can...

    Dead Traction Battery to Full Charge

    I have a 2013 with 66 ahr, BUT with a bad module see http://www.mynissanleaf.com/viewtopic.php?f=30&t=15768. I've been trying to show my dealer that this module does in fact decrease the range of my leaf because they are saying my range is fine and thus there is nothing wrong with the battery...

    Removal of factory mud flaps

    I'm wondering how easy it is to remove the factory installed mud flaps and especially if doing so would leave ANY marring of the finish or any other type of blemish. The reason for this is that I find the design of the mud flaps for the leaf are very good at catching snow and ice as you drive...

    Brand new 2014 has 255 GIDs on 100% !!

    Playing with your numbers, This would appear that when your GIDs were only 255 or so, you had a usable battery capacity of 76/3.8 = 20 kWh above VLBW, and if you included the 8-9% SOC below VLBW, you would have a usable battery capacity of 21.7 kWh which I would think is pretty good. Now that...

    Bad Cell Module and balancing issues when braking

    I finally got around to posting this. At 100%, the bad cell is still obvious and would meet the formula criteria. But from what Cliff posted, the minimum cell voltage is too high for the test to be valid and of course the variation is only a small 27 mV. I will say that I started looking...

    Bad Cell Module and balancing issues when braking

    I'd like to do that, but there isn't a QC anywhere that I can drive to. I got the car with a dealer swap and that 1 QC was already done before they swapped it. So you (xado1) think the Hx is too high? I thought that the Hx numbers were all bogus anyway.

    Brand new 2014 has 255 GIDs on 100% !!

    You 'may' want to also consider the energy hidden below Turtle. I think most will say you immediately pull over when you get to Turtle, but last month I drove just over 2 miles (very level @ ~25 mph) on Turtle in a rental Leaf in Orlando and I made it to a charging station! No way this was on...

    Bad Cell Module and balancing issues when braking

    I have a 2013 with 2100 miles that already has a bad cell pair according to the equation provided by Tick Tock in the thread http://www.mynissanleaf.com/viewtopic.php?f=30&t=11399&start=10 I have seen many posts about high cell variations, but I don't think I've seen any that have this high of...
