Timecapsule 2015, dodgy battery troubleshooting

Sun Oct 28, 2018 11:42 am

Hi all!
Just bought a leaf that is properly messed up. It only manages a measly 15miles (25km) range. I really need some help.

Spec wise, USA model, 2015, 24kWh, 12bars, 3k miles (5tkm)

Car has had one cell repaired according to service logs, since it has been sitting for most of its lifetime.

So I bought it, thinking it was gonna be OK once the cell was repaired. Oh boi how naive.

The symptom:
So when I started driving it the first time, dash says 12/12bars and 100miles (155km) range. After driving 5miles, dash still reports 11/12bars. After another 5miles, the GOM starts dropping fast, and the bars aswell. After managing the measly 15 miles, GOM is down to 29miles left, 5/12bars and I seriously doubt it will manage another 5miles due to how rapid the GOM goes down. It takes away a mile every other second!

So i fastcharged it. Rinse repeat, same story. Here is how little the fastcharge added back to the car. 2.89kWh.

After the third fastcharge that day, the car went into turtle mode with full battery. Also the "check engine?" light came on.

Whatafaak, I thought turtle mode only was supposed to come on with low battery?

So I had to leave the car in the middle of nowhere, ordered a tow, gonna wait a few days to get it shipped back home.

Help! I am gonna try to get leafspy and check the codes and battery. But something seems so wrong, surely 15miles out of a car with only 3000 miles on it is wrong? Anything similar happened to someone here? I am kinda stuck with the car, since I bought it from a private seller :/

You almost certainly still have one or more bad cells in the car. The voltage in that one or more cells is dropping much faster than the other cells in the pack, causing the car to go into "turtle" mode even though the rest of the pack is almost fully charged. A battery pack is only as strong as its weakest cell and you have at least one VERY weak one. You need to use LeafSpy on the car, to show which and how many of them are bad.

I've read here that Turtle mode comes-on when any one of the cells drops down below a minimum voltage. It is completely independent of the amount of energy in the battery.

In the USA , we have a law called the "Lemon Law," which allows a car buyer to return the car if there is a serious problem. I don't know if Finland has any similar protection, but you may want to return the car, if possible.

If not, the battery should be under warranty until 2020: Google "2015 Nissan LEAF | Warranty Information Booklet". I think the dealer could see if the problem if they run a "cell pair test."

Yeah I am still waiting on the flatbed to deliver the car. Should be here sometime this week.

I also booked a service appointment for the car at the local Nissan dealership. Not feeling very hopeful about it. The time is next tuesday.

As soon as I get the car, I will try to look at the codes with leafspy, and also check the battery health.

The bad news continue, just received this email

"Nissan Nordic Europe Oy has not imported this vehicle therefore responsibility lies on selling dealer / importer. As Nissan Nordic Europe Oy has not imported this vehicle we don't know what has been done to this vehicle, where and how it has been serviced.
Vehicles that have been sold in Europe have Pan-European warranty, this vehicle doesn't.
Unfortunately we can't help you in this matter and offer goodwill. I suggest you to contact the selling dealer or the person who has imported this vehicle."

What the heck do I do now? :( :cry:

Does EU law allow for suing a seller for fraud if they seriously misrepresent the condition of a vehicle they sell?

In Finland it is very rare to sue someone. The buyers protection has many steps to rectify the purchase of an used car, which goes something
like this,
1. Talk to the seller. Work something out
2. Get an estimate for how much the repair will cost.
3. Ask seller to pitch in out of goodwill.
4. If not successful, then try to reverse the buy and refer to the law paragraphs etc.

Not a single mention of suing :) Main focus is on getting the car back on the road as fast as possible.

I got a call saying that the flatbed will arrive tomorrow morning, already got Leafspy pro and an OBD2 dongle, so expect some screenshots tomorrow :)

After trying 3 different ELM327, I finally found one that works!

Here are the results:

So it seems like the monkeys who replaced the cell in the car did not pre-balance it. Guess the next step is to open up the pack, and charge it manually up to 4.1V like the rest of them with a LI-ion CC/CV charger. Wow the Leafspy Pro is a great tool!

The weak cells (module) may charge to 4.1v but may not hold their charge under load, if you have any success let us know
BTW very low km's given the year and amount of charges, something funny there.

My guess is the two weak cells were not replaced. If they really were replaced, then they may get balanced by driving gently to get the other cells discharged as much as possible and then charging at a slow rate. It may take several charge/discharge cycles (at low charge/discharge rates) to get the pack balanced. I suggest driving as much as you dare and then running climate control until car shuts down (after parking in front of a charging station).
