Hello Cora, thank you for dedicating your work to things that are truly useful to people. I am a simple European who admires your work and dedication to a topic that I love. I have two electric cars and it's a wonder that you're starting to provide solutions for people with cars that are a few years old.
I wish the same could be done to my Ford Focus Electric, even a range of 250 miles would be a huge improvement. Nissan Leaf owners are lucky to have this option.
@@phphph6022 Adding cooling or heating is a complex project and the cost/risk and benefit are not justifiable for Leaf owners. There are CCS to chademo converters on the market now, you can learn more about them.
@@tarant315 Yes, we replace the original soft battery pack with big CATL cell, which generate less heat and bear a much smaller C rate. The big CATL cells can withstand 3C charge/discharge and can also withstand continuous charge/discharge of more than 1C. Take our 62kwh for example, fast charge power of Leaf is 47kw, at maximum current of 150A, we replace with180Ah big CATL cells, so the charging rate is even less than 1C. So the temperature raise even in quick charge is fine.
There are more than 75000 Nissan Leafs in Norway but no possibility to upgrade batterpacks. I have a 30 kwh 2016. Does a upgrade to a 62 kwh require any upgrade of brakes and suspensions? Does a switch to a bigger battery pack also require any upgrade of software and connectors? Maybe there is a need of a new certification from the authorities since the car probably gets heavier?
Leaf is a very nice car, and it's a shame that it will become a disposable car if you can't replace the battery. No, you don't need to upgrade the brakes and suspensions for 50kWh or 62kWh. For the software, just reprogram the BMS and the car can will recognize the new battery. The 62kWh weighs 48kg more than the original 30kWh, but the 50kWh weighs almost the same as the original 30kWh, so maybe the 50kWh is a better choice for you people there.
@@servantofjc316 The weight of 75kWh is about 416kg, which is 101kg heavier than the original 40kWh, have to upgrade the rear suspension after replacing the battery
I hope someday I could get a replacement Leaf battery with Sodium Ion cells. It's very cold here and I lose about 40% of my range in the winter. I don't even need DC charging, I just need good cold weather performance.
The cooling method remains the same as the original one, but we replace the original soft battery pack with big CATL cell, which generate less heat and bear a much smaller C rate
From 39% to 67% (28% of battery capacity) in 23 minutes with power 42kW gives total capacity around 58kWh, not 75kWh. Or I'm calculating wrong? Or charging curve (battery percents) is not lenear?
Wow amazing! your calculation is correct. You are really careful and smart.👍 Due to the mistake of the colleague who was responsible for installing the battery pack, the battery was installed with the wrong BMS at the beginning(installed as 62kWh). I found this problem when I was doing the fast charging test. However, it was too late to change the BMS and do the fast charging test again, so we continued to complete the test with the 62kWh BMS (the test results were the same). After the fast charging test was completed, we changed to the 75kWh BMS, and then did the high-power discharge test.
@@trailingupwards However, 75kWh requires cutting the battery case and upgrading the rear suspension, so it is not recommended. 50/62kWh is a better choice.😜

@@CoraLiu-VIVNE Here near Seattle. There is a company that offers 62 kWh packs, but they are made with refurbished cells, and they charge $15,000. They also upgrade the rear springs. They offer 40 kWh packs for $8000. You should open a store in or around Portland, where there is no sales tax. People from around the PNW will drive to you to buy your battery packs. It looks like building new packs from CATL cells is pretty easy since they are large capacity cells compared to the original leaf cells. So, it only takes a few of them, compared to 96. How many CATL cells does it take to build a 62 kWh pack?
Would be nice to see inside the pack but guess you have to keep it secret. Standard teplacement 62kwh packs off the shelf would be good. Give an old car a new lease of life!

@@aneeshzutshi3419 Yes, our upgraded batteries have increased capacity, so the same power will have less load on large-capacity cells and generate less heat. Not recommend adding cooling.

We provide 2 year or 80,000kms(49710 miles) warranty, whichever comes first. During the warranty period, if anything non-repairable happens, we will replace with free new modules and shipping freight is on us too.
You will be lucky to get more than 400 kms with this battery pack. I own a 2019 40kw leaf and despite what the range meter says, 200 kms is all you will get.
It depends on a lot of things, the 62kWh can do well over 300, so 400km might be possible. The real benefit is that a fast charge to 80% will get you to where a (slow) full charge to 100% on a smaller battery would have been.

Very interesting! I have two questions; can you add cooling/heating to manage the battery better? And can you change from chademo to CCS?
Was just asking myself, if the leaf battery pack is even more dense... You really need active cooling to fight the famous degradation on these packs.
