VIVNE-Nissan leaf 50kWh battery pack fast charging test(Part 1)

#nissanleafbattery #nissanleaf #electriccarbattery
Today we completed a fast charging test under extremely hot weather conditions, the outdoor temperature reaching over 40 degrees Celsius, The SOC was charged from 12% to 100%. During the entire charging process, the battery temperature rose from 34°C to 49°C, a total increase of 15°C. The maximum temperature of the battery is 49°C, which is not exceed the operating temperature range of CATL cells(-20~55°C). lt also did not reach the limit value of Leaf VCM suspending charging.
Unfortunately, we forget to record the charging curve this time, we will record it in the next test so that everyone can see our charging test results more clearly, because in order to ensure the accuracy of the test results, we will do the same test two more times. so please continue to follow my channel.

Great information Cora.
If it did not overheat in those temperatures it is not going to have problems any where.
CATL did a great job on those batteries.
Thx

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.

Next time watch some videos from Bjorn. As far as I could check, the initial charge speed was ~40kW. It would be good to have a charging curve because total charge time is meaningless...nobody charges to 100% on a fast charger.

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.
