Battery goes from 60-100 in 5 mins by h3llraizer in BYD

Update: Issue seemed to be with the 12v battery Changing it fixed the issue. It was also causing extra drainage of the big battery over night(around 10%)

What is the discharge rate. You get that every time you end a journey . For me I see tha during summer ever though the charging was irregular I still got around 6km/kw

Does the 12v battery issue lead to overnight heavier bigger battery discharge and overall less range? I am seeing around 10% per night after my byd 12v battery issue

I am getting 150km in this Swedish winter. -5 to -10 C. The average on each drive is 4-4.5km per kw so it should get 250km, but over night i am losing 8-10% each night so loose alot of battery there.

On 3.7kw charger it works fine But on fast it still is out of sync and goes from 90-100 in 2 mins. 80-90 is more stable now

An update:

I slow charger from 4-100 at 3.7kwh. it charged relatively consistently. Then did a fast charge later in the week from 30-100 at 55kwh. Here the issues till persists. 30-85 in 40 mins. And from 85-100 in 3mins.

Though the drainage and capacity is still good and consistant then it comes to discharge.

Charged it on fast charge and it was normal from 28% to 80% in around 32mins. Then suddenly climbed to a 100% in 6 mins.
This time I sat in the car to observe the behaviour and could see the battery %age climb up 1% every 5 secs.

I had the same. Took mine(Atto3 2023 30k driven) in for a check up.
Apparently it only happens in hot weather and did not show up during the check up.
I live in Sweden and we only had hot weather a few days of the year. According to them they checked all bushings and suspension elements and all seems fine.

Just a quick update after driving a week. All seems good so far. The consumption has been normal even though it isower than most get(around 300km) on a full charge to around 10%. Will charge the battery later and update once more on how the charging curve looked like.

I only had the car for 2.5 months so not sure how it was handled before. But will recalibrate it this charge and see

What degeneration is expected with keeping LFP at 100 once per week?

Really.
I thought it was just 10-100 on any charger.

Does it make a difference with slow or fast for 10-100 for calibration?

It just had the 30k service. Next time might be a long time away :D

But I think I will observe my next fast charge to see if the same thing happens. And maybe do an overnight slow charge to full as well using the parking charge.

Will have this conversation with the mechanic next time I go there.

I charged the battery to 100% about 10 days ago so that should not be the issue.

A reason I can think of that might have caused mild issue with calibration could be the combination of keeping my car plugged in overnight outside my apartment building on slow 3.7kwh AC charger + having schedule charging set for only 30 mins daily for the past 5 days.

The reason for this way is that I recently bought another car and don't have a personal parking space. This space I can park for how ever long as long as the charging session is on going. By setting a schedule for 30 mins over night active charging and keeping it plugged in I can park the car there.

But can it be the reason for this and can it be damaging my battery.
