Thanks JejuSoul, I see the graph now.

I agree that it's the same as with the Soul. First stage has current limit 125A, voltage target 390V. Second stage has about 55A current limit and voltage target 394V. This is the same as I see in my car. The SOC% is probably a bit lower due to the bigger battery capacity.

Maybe there is a SOC confusion in the user group discussion you refer to? 84% user SOC (which I refer to) is actually 80% total battery SOC.

To be more precise, the cell balancing in my car always appear at 81.5% user SOC, corresponding to 78.0% battery SOC.

cell phone : 15 Wh,
max 1.5A continuously, and die after 150 cycles with this current,
max = 750 cycles at 0.5A (dead, really ...).

EV Battery : 29 700 Wh,
max 230A continuously and don't die ... at all !
max = 3800 cycles at 75A (70% good, 30% used).

cell for an EV battery is not the same cell for a phone : viewtopic.php?f=14&t=774

It seems both the new N issan L eaf and the new Soul EV will keep Chademo and not swap to CCS.

So this is good news. - https://www.facebook.com/groups/SoulEV/ ... 705567406/

Tony Williams wrote:The revised CHAdeMO standard (ver. 1.2) was formally announced on March 24th, 2017.

Whereas the standard maximum current for Direct Current Quick Charging (CHAdeMO standard) had previously been limited to 125 Ampere, the revised standard increases maximum current to 400 Ampere, enabling an increase in charging output from 50kW to 150kW. This helps further improve the convenience of plug-in vehicles by shortening charging times to approximately 1/3 of previous charging times.

T esla Superc hargers operate at 365 amps today.

Thanks SoulEV2016.

Having faster charging available for long distance travel makes sense. Especially with the bigger batteries that will soon be available.

However these are what have just been installed at the local beach. 20kW c hargers with double Chademo connectors.
I don't know if it will do both cars at the same time 10kW each, or one will wait for the other to finish. Will test soon.
Two have already been built, There's 5 more under construction.

They also have this kind at the rental office near the airport.

Korea is supposedly switching to CCS only from this month and yet all these new c hargers are Chademo only.

I just used a CHAdeMO for the first time (had the car 18 months but there haven't been any Level 3 chargers around here). It was a Delta and it kept starting to charge and then immediately stopping with "Status Code: 114001, Charging termination". I found I needed the charge timer override button out i.e. the opposite of trying to charge immediately from a Level 2.

Search for the 394v target (pass from 390v CCCV to 394v target on Chademo charger).

OK, find by an other french member : cut the chademo at 82,5% and the 394v target is available = more time at 22kW for the 94% goal.

Here's some photos of a specially modified L eaf charging with 150kW Chademo at a recent preview in Japan.
The c harger is a dual Chademo Signet. We have one locally, but I don't think it is 150kW.

Update - I think my post below is mistaken. There was no cell balancing after charging finished. What happened is that Torque froze when charging finished. I didn't see that the cell balancing had already occurred at the exact point charging finished and the voltage had dropped until I turned the car on a minute later and Torque re-started..

Here's a Ray EV chademo session - charging from 10.5% to 80% .Took 18 minutes. Ambient temp = 20C
This post is to talk about the cell balancing at the end.
I originally posted this to talk about the capacity of the pack here - Comparing BMS data on the Soul EV with the Ray EV

Image

The Ray EV only has SOC BMS, which changes from 2% at empty to 90% at full. There is no SOC Display.

In the charging session above 80% is reached after 977 seconds. One second after this the Energy Charged counter stops increasing.
At 1064 seconds the charging session ended. I think cell balancing is occurring for the roughly 1 1/2 minutes at this point.
During that time the energy draw remains constant at -26.8kW but nothing happens to any of the counters.
Battery Voltage stops at 368.1. Max cell voltage 4.18V. Min cell voltage 4.16V.

At 1063 seconds the cell voltage deviation drops to zero. One second later the charging session ended.

At 1064 when the c harger stops there is a drop in Battery Voltage to 357.0 V

Interestingly the time seen on c harger does not include the balancing part. Seen from the display on the Chademo stand. Timer stopped at 16 mins and 19 secs = 979 seconds. Had I been paying by the minute I would not have been charged for the 1 1/2 minutes that the cells were balancing. This c harger is currently free. Later it will cost 178 won per kWh. (about 20 US cents / kWh).
