China's national mandatory standard CATL battery cells cycle life is at least 2000 times

We did that😀, we can provide battery upgrades for the entire range of Leaf vehicles, can upgrade to 40/50/62kWh, you can add my WhatApp: +8615211174371 or send me Email: cora@vivnevs.com for all the details if you need

@@fernandinand The 40kw fast charging power lasts until SOC is about 70%. Unfortunately, there is no English version of this fast charging app. I have marked the key data as much as possible. If you still have any questions, please feel free to discuss with me.

@@CoraLiu-VIVNE If constant charge curve @~40kW reaches 70%SOC, that means we should charge this pack from ~20% to 80% SOC in about 45 minutes? That's the real test a regular user wants to see...not a full charge on rapid charger from 5% to 100% (IMHO)

@@fernandinand Thank you, that is a good suggestion. In fact, our test this time is to check the temperature changes of CATL battery cells during fast charging in extremely hot weather. We will find an opportunity to do the test you mentioned in the future.

@@CoraLiu-VIVNE please make a high power charge test with 2 stops for a regular long trip with around 500km in order to check for rapid gate charging issues. That would be a normal real world test.

@@fernandinand Very good suggestion, we will arrange it as soon as possible, let us look forward to it together.

@@silvy7394 When the battery level of the lithium battery is lower than 20%, it is normal for the voltage difference to be slightly larger. There are two reasons for this. First, the discharge curve of each battery cell cannot be completely consistent, which will result in different voltages. Second, when the battery level of the lithium battery is low, the internal chemical reaction will be unstable, which will also result in different voltages between the battery cells. We usually focus on whether the voltage difference value is appropriate when SOC is 20%~100%.

This is an old Leaf, not a particularly "modern" car.

@@xcylium Yes, this is also the charging capacity we recommend

Thank you for your valuable suggestions. This is our first fast charging test, we ignored the charging curve at that time. Next we will do the same test two more times, and the charging curve will be shown in the video, please kindly continue to follow this channel, thank you.

@@CoraLiu-VIVNE Great! I like your R&D but I need to fill some holes on the information you provide in order to make a judgement for the next ~2 years....the timeline I would need a swap on my 2014 Leaf.

Yeah, in order to ensure the accuracy of the test results and eliminate the interference of accidental factors, we will do two more such fast charging test soon, please continue to follow my channel, thank you.

BMS is battery management system, after the battery upgrade, the dashboard cannot display the correct mileages, our solution of reprogramming BMS can perfectly solve this problem. We don't sell BMS, only provide BMS programming services. According to the normal process, need you to provide us your original old BMS first, and we will reprogram it and then send it to you with the goods, however, considering that your car will be temporarily unusable after removing the BMS, we accept to provide you with a programmed BMS first (sent together with the battery), and you can send the old BMS back to us after receiving it.

@@CoraLiu-VIVNE Is it a PCB ? And where is it located ?

@@ALEX-bs4wi The BMS is installed in the battery case. You can check out our Alibaba link here which contains some pictures of the BMS and its location, thank you： www.alibaba.com/product-detail/Reprogrammed-BMS-For-Nissan-Leaf-Mileage_1601221393256.html?spm=a2700.shop_plgr.41413.1.2e4f7121AsvmVf

Thanks for your comment, please see the reply as below: 1) Yes we have a video of the car driving, this is the video link, please take a look: th-cam.com/video/MQVeqKroVwY/w-d-xo.html 2) We are preparing to record a fast charging test video, so you will see the fast charging speed and the temperature change of the battery, please continue to follow my channel. 3) The cooling method is the same as the original one, 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 with 180Ah big CATL cells, so the charging rate is even less than 1C. So the temperature raise even in quick charge is fine 4) For the weight, 62kWh battery pack is only 85kgs heavier than original, so you don't need to modify any parts of your car For more details, welcome to add my WhatsApp: +8615211174371 or send me Email: cora@vivnevs.com, thank you.

I guess there is no have liquid in this budget EV . Avoid fast charging and everything will be alright .

No liquid cooling and no need to increase it, We replace the original soft battery pack with big CATL cell, which generate less heat and bear a much smaller C rate.
