Re: Dala's Leaf buildthread (2015 Nissan Leaf)

This showed up in the mail. https://i.imgur.com/1FlsIWz.jpg Now I can start capacity testing the big Leaf cells! I settled on the reasonably priced Antimatter charger/discharger. It can do 10A charge and 7A discharge. I started it a bit more gently, and the test is going to take some time. I set the...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

I finally caved in, and started renting a garage space 200m from the apartment. It costs 50€ per month, with unlimited electricity. This solved my range anxiety issues permanently. I am limited to 8Amp charging, but that is OK, I only need this space once or twice a week. I should have just done thi...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

Happy holidays! The Leaf is happily churning out spruces as I drive, very festive :) https://i.imgur.com/YakumgF.jpg I am continuing the LED upgrade, here is the boot space lamp https://i.imgur.com/vdOS2B1.jpg And here is the dome light. Both got 31mm wedge LEDs. https://i.imgur.com/n3U0yfM.jpg I ne...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

So Christmas came early, and the previous owner sent me an identical cell from the batch he used to 'fix' the car. It is from USA and has 30 written on it. If I were a betting man, I'd say that the 30 stands for 30Ah measured on one 4V cell. That would be a 33Ah->30Ah, 90.1% degraded cell, which mak...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

This is the reason electric cars are impossible for most. I could manage with an electric car with the city driving I'm mostly doing, but as you. I do not have the possibility to charge it at my place and the workplace charging station is only for two cars. Also electric cars are still a bit on the...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

So I've now driven 600km with the leaf, might give you guys a status update. The charging situation is not ideal to say the least. Neither my apartment complex nor workplace wants to let me charge. So this leaves me with only public charging places (3x in my city) and the occasional visits to parent...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

I just went 80km on a charge with heat on, then the low battery warning popped up. But all is not doom and gloom, I got my hands on a cell! https://i.imgur.com/0KA4Xlk.jpg It came from Italy, a company that specializes in conversions and home-brew scooter solutions. It was cheap, and SUPPOSEDLY low ...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

So I finished the bottom balancing. Here are the results I was hoping to get a peek of the model number for the shitty replaced cell, but unfortunately it is below the visible sheet metal. https://i.imgur.com/DkiwwEX.jpg Here is the car, fully charged. Note that it only goes to 83% SOC, limited by t...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

After completing the rough balancing, the car can now go 85km instead of 25km. Still really bad, should be closer to 150km. So the troubleshooting continues. I contacted a company that specializes in EVs, (EVs Enhanced), and they suggested doing a bottom balance instead of middle balance. This makes...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

While waiting for emails on potential cells, I decided to do my first mod! It's quite common in Finland to do grille blocks during winter, this allows the engine to heat up more rapidly and improve efficiency. But wait a minute, this is not an internal combustion car (ICE), so why do it to an EV? -I...

Re: Dala's Leaf buildthread (2015 Nissan Leaf)

After charging the cell up and letting it sit for 16h, it unfortunately drooped back a few mV, indicating high internal resistance. It will have to be replaced in the future, but the car should be usable now, so I spritzed some bathroom silicone around the battery, and popped it back in to the car. ...

Dala's Leaf buildthread (2015 Nissan Leaf)

So I thought I might start a project thread on this car, that wasn’t supposed to be a project. I recently picked up a commuter, 2015 ZE0 24kWh Nissan Leaf, with 5k km on it. It has extremely low range, the guess-o-meter(GOM) on the dash says 160km, but as soon as you start driving it you are lucky i...

Re: Dala's 100NX

After giving the ignition system a complete overhaul, it was time to set the mechanical timing to match with the ECU timing. I grabbed a trusty stroboscope and went to town, only to find out that I had no visible markings on the crankshaft pulley. The torsional damper frickin slipped. Time to get a ...

Re: Dala's 100NX

Time to update what's happened in the last few months.The whole ignition project grew in size, what was supposed to be a quick ignition upgrade turned into an open-source ignition platform. The DIS_SR board designed by ebinkered was ultimately scrapped. Interference on the sequencing was the final n...

Re: Dala's 100NX

The COP board design is evolving. http://i.imgur.com/Tu2faw6.png To try and combat the glitches, we utilized opto-isolators between the sequencer and driver side. By also removing the edge connector, there are less overlapping traces on the board. These two changes will drastically improve the noise...
