What with your car skittering all over the road and now this latest issue, sounds to me like you've got a lemon, JB.

I don't think the car is a lemon, I think it cutting power is the way I drive it.  I am not sure if my PM2.5 inside the car display is accurate or nailed on 5 by design.  If other Seals do display PM2.5 correctly then I suspect I have a problem.  What does your inside PM2.5 say?

Sorry, I was trying to be funny!

 

I need to check what my PM2.5 reading is. May not be driving the Seal for a few days.

I forgot you were British and therefore REALLY DO have a sense of humour.

Mine says:

Inside 5

Outside 25

 

Gave it the Quick Purification and it stayed the same.

Would be interesting to open the windows for a while to see it go up then see if it brings it down quickly !

It’s a reasonably smog free day here so it is in your hands JB .

[Alotoftravel]

JB,

 

I saw this on Facebook of their pm2.5 reading here in chiang mai .

it is certainly not 5 .

I saw 320 outside on my car yesterday. I opened the doors and tried again, it still reads 5.

 

The Atto 3 does appear to be accurate.

[Andrew Dwyer]

Opened the doors for 5 minutes and the inside/outside equalised 

 

 

Closed the doors and in 2 minutes it was back down to 5 inside, but no lower.

 

 

Tried the Quick Purification a couple of times but it never gets below 5 inside.

 

 

Make of this what you will .

Pm 2.5 is essential here up in the north. I  am sadden to read the new 2024 BYD Otto dynamic 480 priced at 889k does not have it . It might be an omission by the media publisher . Anyway at least the next model, 945k Otto 3 premium 480 has the pm2.5.

Just to clarify, that’s the 2 x 410 models ( formerly known as Standard ) with a battery around 50 kWh.

The 480 models ( 60 kWh battery ) will be showing the updated version at the Motor Show later this month .

[Alotoftravel]

Andrew,

thanks , my bad . I meant the 50kwh standard dynamic 410 for 899k model . 
I am sure the BKK motor show will confirm if this model has pm 2.5 filteration present .
Thanks .

I can confirm the new 410 models all have PM2.5 filtration, the cheaper model does not display the PM2.5 level, it probably doesn't have the sensors but it does have the filter.

Seal

 

Not even sure what car that is on the last photo with the split centre arm rest ??

 

Uses a similar model picture on the app when charging ( is that an Atto 3 ? )

 

 

Eagle eyes might notice that the charging speed is 4.6 kw , while is normally 6.4 kw !!

 The air con has decided to kick in at high speed, wondering if that’s the reason ?

Air Con cooking in is probably battery temperature, that would explain the slow down in charging speed too.

Yes, a couple of minutes later the car decided it was cool enough, stopping the air con and charging speed back up to normal.

As FYI....a few weeks ago I was charging my Atto with my Zhida 7KW wallcharger  (the one provided free by BYD when buying the Atto back in late Oct 2023)...my Atto normally displays a charging rate of  6.3KW on the Atto display and the A/C has "never" automatically turned on to cool the battery.  But a few weeks ago while using the wallcharger the A/C would automatically turn on about 5 minutes into the charging session and the charging rate go down to around 5.7KW.... and even after 20 minutes or so the A/C was still running.  Having used the wall charger "many" times since late Oct 2023 this had never happened....and a little ol' charge rate of mere 6.2KW should not cause any significantly battery heating.

 

I stopped the charging, unplugged the cable from the car, and restarted the charging several times.  Even killed power to the charger/rebooted the charger a few times and restarted the charging from scratch.  But each time after 5 minutes or so the A/C would turn on automatically again like it need to cool the battery while charging. 

 

I then unhooked the car and drove to a nearby EA Anywhere 90KW DC Fast Charger.  Started the charge...it started charging at around 87KW (as displayed on the Atto...the Atto has a max charge rate of 88KW) and the A/C would "not" automatically turn on.  I figure if a charging rate of 87KW on a DC Fast Charger does not trigger the car A/C to kick on then my little old AC 7KW wall charger shouldn't either.   

 

Went back home started charging again with the wall charger and once again after a few minutes the A/C would turn on.  So, I stop the charging again and tried something different.   This time after unhooking the charging cable from the car I then used the "Reset" switch on the bottom of the wallcharger to Reset the wall charger (it's a healthy sized red knob you turn to reset).  Repeat, I Reset the wall charger with its Reset switch.   I then connected to the car again and start charging--and now the A/C does "not" come on....it's charging normal again...A/C not turning on after a few minutes.    I repeat the process a few times...still OK.  And I have charged the car probably a half dozen times over the last couple weeks (primarily to see if the A/C turning on while charging issued came back) and everything is still fine.  In fact I'm charging my Atto right now (been charging a few hours now) after running it down to 3% charge remaining...I got a realworld range of 441Km which exceeds the Atto's 420Km "WLTP" range rating.

 

But the key point is apparently "Resetting the wall charger" by using the charger's external Reset switch fixed the issue.  Apparently the charger's software/firmware/settings/etc., got confused and the Reset fixed it.  It was not a car issue but a charger issuer.   Before I had been briefed by the charger installers to use the Reset switch whenever a Warning/Fault light appears on the charger and the charging stops....something like that has never happened.

 

So, I know there are various wall chargers provided by BYD and if they have an external Reset switch and you encounter some weird charging problem then "resetting" the charger may fix things --kinda like using "Restart" on a Windows-based computer as a Restart works differently than a Power Shut Down/On.

Thanks, it has happened 2 or 3 times before but I never thought to look at the charging level and left it to resolve itself/cool the battery. Usually 10/15 minutes is enough.

There has been some discussion on FB groups ( Atto and Seal ), and I think @macahoom mentioned it after the first Seal OTA update, the general consensus being it was just cooling the battery.

 

I don’t think anyone has pointed to the wall charger before but i will look into the reset mode on this ABB charger and give it a go if it happens next time, probably next weekend.

I think the reset switch on the wall charger stopping the A/C is coincidence as turning on the A/C is entirely controlled by the car and not the wall box.

 

The A/C probably cools the battery and the AC to DC charger onboard the car which is probably getting hot.  If you DC charging then the AC Charger isn't used so won't get hot.

 

Generally speaking, if you can avoid it, don't charge your car at home until after you have let it cool down for 40 minutes or so if you were just driving it.  Thailand is a hot country and your battery is going to be hotter than the ambient air if you were just driving it.

Yes, the 1st time it happened i stopped charging as it was very loud left it for a few minutes, restarted and the air con never kicked in again so yes I also think resetting PIB’s charger is a coincidence.

Now i just leave it do it’s thing as figure it is necessary.

 

Had read on fb groups ( both Atto and Seal ) about the air con kicking in loudly ( probably Auto setting ) while charging, the recommendation was not to start charging soon after driving and I adhere to this.

Probably the worst that could happen is that the air con would kick in earlier but could be detrimental to long term life of the battery i suppose.

What may be going on here for some folks with the A/C kicking on while charging has nothing to do with cooling the battery especially at a mere 7KW charging rate which causes very little heating of the battery...far, far below the battery's max charge rate.....but instead the A/C is turning on to remove any moisture left on the A/C "evaporator" fins (i..e, the inside the cabin portion of the A/C like the inside portion of a home split A/C) to prevent mold build-up on the fins)    This A/C turning on is probably being triggered by the person opening the door a little to peek at the car display to see if and how charging is occurring because it can be hard to see by looking thru the window which may be tinted, then closing the door and then locking the car to leave the car area....then very shortly after locking the door the A/C "may" automatically turn on.   The A/C automatically turning on will not occur every time but frequently (say 1 or 2 times out of 10 times) trigger the A/C to turn on at a low level.

 

I can often trigger my Atto A/C to come on by going to the car which may have been turned off for hours or even all day while setting in my shaded carport by "partially" opening the door for a few seconds like I wanted to quickly grab something in the car or if I was charging to peek at the display to see if & how fast the charging is occurring---and then I lock the car.  Within about 15 seconds or so of locking the A/C might turn on....and run for about 15 minutes before automatically turning off.  

 

And the way to make the A/C turn off when it started up automatically by this door opening/locking is to then use your key FOB to unlock the door and then immediately use the FOB again to lock it....that is, click the FOB to unlock and then immediately click the FOB to lock....this will cause the A/C will turn off and stay off until you want to turn it on again like just starting the car and the A/C starts automatically to whatever A/C settings you have cranked in.   Now if charging while doing this FOB lock & unlock sequence it may cause the charging to temporarily stop for 30 to 60 seconds (I mean go to zero charging) but then it will start charging again automatically in less than a minute.

 

What is causing the A/C to come is "not" charging related...not battery cooling related....but A/C evaporator fin drying related.  It's because the car wants to remove any moisture on the evaporator fins to prevent mold formation, smell, etc.  The car is programmed to operate this way and has nothing to do with battery cooling in this particular case when the A/C just turns on when the car is not started.    I expect the Atto, Seal, and Dolphin all act the same way.  

 

At bottom see the snapshot from the Atto manual.  Now the note implies the A/C "typically" keeps on running after parking like maybe going to Big C, parking, and getting out to go into the store.  But my Atto rarely does what the note implies that the A/C blower will keep running for a while after turning off the car...nor will it turn on automatically when locking the car after driving it.   But as I mentioned earlier I can frequently trigger the A/C to come on while setting right in my shaded carport where it has been turned off for hours...I can do this by opening a door a little just for a few seconds, closing the door and then locking the door....within about 15 seconds the A/C might turn on for about 15 minutes.   Now where I say "frequently trigger" I would guesstimate this to be around 10% of the time.   It's a normal thing for BYD EVs based on my research/googling/youtube watching/manual reading/etc., as the car thinks it needs to dry the A/C evaporator fins.  But as mentioned when the car does this you can easily & quickly turn the A/C off my using the key FOB to click unlock and then lock...the A/C will turn off and stay off---or at least that's been my experience since owning my Atto for 5 months now.   The A/C magically turning on issue is not related to charging but related to drying the A/C evaporator fins...the car programming/sensors feeling it needs to dry the A/C evaporator fins.

 

P.S. last night while charging I did a test to see if I could trigger the A/C to automatically come on by merely opening the door a little for a few seconds like I wanted to peek at the EV display to check the charge percentage....I then closed the door and locked the car....and then within about 5 seconds the A/C turned on.  This locking caused the charging to temporarily stop but the charging restarted automatically within a minute.  I then used the key FOB to unlock and lock the door again and the A/C turn off.  The charging temporarily stopped again but restarted within a minute but the A/C did start again automatically because the little trick of using the key FOB to click unlock and then lock somehow tells the car there is no need to start the A/C.

P.S. last night while charging I did a test to see if I could trigger the A/C to automatically come on by merely opening the door a little for a few seconds like I wanted to peek at the EV display to check the charge percentage....I then closed the door and locked the car....and then within about 5 seconds the A/C turned on.  This locking caused the charging to temporarily stop but the charging restarted automatically within a minute.  I then used the key FOB to unlock and lock the door again and the A/C turn off.  The charging temporarily stopped again but restarted within a minute but the A/C did start again automatically because the little trick of using the key FOB to click unlock and then lock somehow tells the car there is no need to start the A/C.

So, nothing to do with resetting the wall charger ?? all that did was interrupt the cycle.

 

Why don’t you use the app to check on the charging situation ?

I recall when I first got the car I would peer through the window to check on granny charging, the key in my pocket would bring the small screen to life, now I just take a look at the app.

 

As I mentioned, first time the air con kicked in while charging I was surprised but now I just leave it to do it’s thing.

 

This conversation only started because i noticed the lower charging level during the air con operation.

In the post where I talked needing to reset the charger it had everything to do with resetting the charger.....the charger was just confused, corrupted settings, etc.   Resetting it fixed that particular issue.

 

But in the other post where I talked people assuming charging of the battery had caused the A/C to come on I was saying it could very well "not" be due to battery charging but instead due to the car thinking the A/C evaporator needs to be dried which is done by the A/C automatically turning on regardless of whether you are charging or not.  The A/C being automatically turned on while the person is charging can be caused by the person opening & locking the car in a certain way which can cause the A/C to turn on for X-amount of minutes--no due to the need to cool the battery but the car thinking it needs to dry the evaporator fins.

 

I see people all the time at charging stations who are outside the car and using the charging app and charging station display to confirm the charging process has indeed started, HOWEVER, BUT, what do many people very often do to ensure the car is really charging although the app and station says its charging?....the people will open the car door to peek at the car display to ensure it's charging and then close &  lock the door while they go kill some time which can then trigger the car's A/C to come on for a while.  Not due to battery charging but due to A/C evaporator drying...but people will wrongly assume the A/C came on because of the battery charging and then all the social media crossfeed reinforces the thought the charging caused the A/C to turn on.   Now battery charging will no doubt probably cause the A/C to turn on if using a DC Fast Charger and the battery happens to be taking in a high KW amount....but a mere 7KW from a wallcharger or lower KW levels from a DC Fast Charger is not going to create any significant battery heating requiring the A/C to assist in the battery cooling.

 

And how a person locks a BYD can determine if the A/C might come on to dry the evaporator.   Like just over the last hour I did a lunch run to Taco Bell in my Atto.  Drove there, parked, turn off the car, got out, locked the door using the door microswitch....A/C does not come on.  Got my tacos, drive back home, turn off/park the car, get out, but do not lock the car....A/C does not turn on....BUT then I lock the car using the key FOB this time and within a few seconds the A/C comes on.  To stop the A/C I press the key FOB unlock button and then the lock button again to lock the car....the A/C turns off and stays off.    What I've found with my Atto if locking the car with the key FOB and can trigger the A/C to come on...not saying it does it all the time...I saying just sometimes...maybe 10 to 20% of the time.   But to the best of my knowledge when I lock it using the door handle microswitch it never causes the A/C to turn on.

 

Regarding use of the BYD App, sure I use it for various things but I do not carry my smartphone around all the time.  If I'm in my carport to hookup the charger and car I don't use the BYD app to lock/unlock the car...in fact, the phone is probably in the house laying on the dining room table.  I don't need any app to use the charger as it's started/stopped by use of a RFID card waved in front of it....the ZHIDA app don't  have/use an app. 

 

Now I do use the BYD app to monitor the charging from inside my house, turn the A/C on early like I'm still in a mall but want to cool off the car before getting back to the car to drive home, etc. But as mentioned when I'm outside the house just doing this-and-that around the house and maybe I'm charging the car during this time I don't use the BYD app; I just open the car door and look to see the current charge rate/percentage....plus my phone is probably laying on the dining room table.   

 

I expect a lot of people who are charging their car in their carport just peek at the display in their car to ensure it charging, then lock the door and go back into the house not realizing that door opening and locking sequence could have triggered the A/C coming on to dry the evaporator and it's not due to the charging.  And quite probably if they had not "locked" the door after taking a peek the A/C would not have come on.

 

Yeap, BYD vehicles are kinda weird in how the A/C can be triggered to come on for 10-15 minutes to dry the evaporator even when the car is not being charged....and as mentioned it can lead to a wrong assumption that charging triggered the A/C coming on.
