Consider lease that faulty Atto3 ?

Sure. Thanks for the advice.

Nah I wouldn't count on that bro. Remember our friend new EV 10 months old je, battery kong forcing the EV into an emergency brake within 6 seconds.

EV charging system is unlike that of an ICE charging system, I suspect battery companies, if they want to sell batteries to EV, they will probably come out with additional terms & conditions for their batteries to be use in EV, simply because the ancient 12V lead acid battery is the cheapest battery but it's definitely not the correct battery to be use in an EV. That is why Tesla upgraded their batteries to a 16V battery for their EV.

While there are accounts from Boy96 saying the batteries last much longer but we have to take into account that Boy96 & geng bukan olang biase biase type, they are up to mark with their maintenance but for Tom Dick & Harry will be asking batteri besar gila bawah kereta, apa that smoll tiny battery masih boleh Kong ?

Pengalaman paling MENGERIKAN bagi kami sekeluarga apabila kereta BYD Atto 3 secara tiba-tiba brek mengejut ketika sedang memandu di lorong kanan lebuhraya!

Pada 1 May lalu, kami dalam perjalanan dari Melaka ingin pulang ke kampung di Penang dan singgah di Kajang sebentar untuk menghadiri rumah terbuka. Sewaktu di lebuhraya Cheras-Kajang, kereta dengan secara tiba-tiba brek mengejut tanpa ada sebarang amaran atau apa-apa 'indicator'. Di skrin panel kereta pula menunjukkan "Power System Failure" dan keempat-empat tayar kereta seperti di kunci.

Beberapa kereta hampir kemalangan kerana mengelak dari merempuh kereta kami yang tiba-tiba berhenti di lorong kanan.

Saya terus menelefon pihak lebuhraya untuk meminta bantuan mengawal lalu lintas. Alhamdulillah, kurang 10 minit pihak peronda sampai dan terus meletakkan kon di lorong kanan agar kenderaan lain berwaspada dengan kereta kami. Saya juga cuba untuk 'Off dan On' kereta namun tidak berhasil kerana tiada sebarang respon. Tayar pula seperti dikunci dan kereta tidak boleh ditolak walaupun gear sudah 'N'.

Dalam 1 jam, pihak towing insurance pun datang dan menunda kereta kami ke pusat servis di BYD Glenmarie Shah Alam. Jam menunjukkan pukul 7 petang dan saya hanya boleh meninggalkan kereta tersebut di situ kerana di luar waktu operasi. Kami sekeluarga terpaksa menumpang di rumah saudara yang terletak tidak jauh dari situ.

Pada keesokan paginya, saya menelefon BYD Glenmarie untuk memberitahu masalah kereta tersebut tetapi mereka memberikan pelbagai alasan seperti, 'tidak cukup staff', 'perlu appointment', dan pelbagai lagi. Disebabkan hal ini 'emergency' kerana melibatkan nyawa, saya tetap menegaskan dan memaksa mereka untuk memeriksa kereta tersebut.

Pada 4 petang mereka memberitahu kereta kami mempunyai masalah bateri 12V dan memerlukan masa beberapa hari untuk membaik pulih dan melakukan pemeriksaan. ...

In the case of the OP incident above, the 12V battery was weak (10 month old) or failing, not totally failed = still got LCD screen showing "Power System Failure" but all other power-drawing functions no more working.
....... Likely the TERRIFYING automatic emergency braking from 100km/h in 6s (= Power System Failure) by the computer of the BYD Atto 3 EV car was to pre-empt total 12V battery failure or total accessories failure, eg no power steering, no ABS, no emergency airbags deployment, etc..

Repeating the same arguments. Countered before.

Yes if you use your critical thinking and common sense, it is also logical that the whole LCD screen all the lights and everything will also fail. Means nothing will turn on. Suddenly only door sensor fail but all the processor , memory , radio system is working .. LOL.
But the LCD screen is still on, the processor is still working. So your logic fail again. Btw there's no 5V battery , I understand similar to the bozo Catholic guy who claims to know electrical systems, you cannot understand what voltage regulated system means.

Imagine what would have happened if it was raining ? Doubt the vehicles travelling at the back would be able to avoid it on time. How come the original text missing the other vehicles managed to narrowly avoid it ?

I am impressed with your patience dealing with that dildo. It's similar to another dildo now tell me where does it say unequivocally that Jesus says he is God in the Bible. It's similar like show me where unequivocally where does the report show that a failure 12V system leads to the shutting down of a system. Thank goodness I have clients who drive modern cars and since I am managing their vehicles don't have no fucking problems. The moronic dildo is fucking with you man.
Surely he has some interest in EV and you continuing to tell the truth will affect that dildo.

Man I can't believe a Christian claiming to be an expert of electrical system managing a "fleet of cars" got himself wrong when he doesn't even know a DC/DC converter is the one powering the whole car up when it is running.
I wonder if he knows that you can remove the battery after the car is running because the alternator is the one keeping the system alive.
LOL, imagine thinking asking a group of people to change battery makes him an electrical expert... LOL.
It's like saying he cooks Maggi mee at home and therefore he's a Michelin star chef.


And then when he can't counter with facts, there comes the name calling.
Imagine a Christian after their arrogance and mistakes , can't take the ego bruise and resort to sex toy name calling.
Well it looks like even the Christian thing is a facade.

BYD already sell like what? 10 thousands of cars the past 3 years in Msia?

If a simple 12v battery failure caused this, there should be at least few hundred cases like this have occured 🤔

So, what really went wrong with this Atto 3? No press conference by Sime / BYD? Lemon unit or something more sinister?

DC/DC converter kaput could be the main culprit. But it seems to occur very rarely. 12v battery kaput is so common its impossible this thing just happen once in this case.

Machem ICE car yes 12v battery kaput is so common. But alternator that constantly charge the 12v battery kaput we very rarely encoutnered it though it can still happened.

they do this so u will further open ur door and step out of ur car, then get bang by car from behind, purpose, asal kerete no damage means the kerete safety features toptiptop

No lah. The running EV car is still running after its 12V battery is removed does not mean the accessories are also still running, eg door system and sensors, lights, etc or such EV car can still be driven on the road.
....... AFAIK, with an EV car running or switched on, the traction battery directly powers the electric (drive) motors, which motors in turn powers the climate control system, eg compressors, ... and recharges the 12V battery when needed, which 12V battery directly powers the accessories, eg door system and sensors, lights, HVAC fan, steering, braking, computer, ADAS, cockpit displays, etc.

Note that the 12V battery also powers the "starter" system, ie it is needed to "wake up" the traction battery's power system, eg a dead 12V battery in a parked EV car that has been switched off = a dead EV car that cannot be started or "woken up" = may need to be jumpstarted or the 12V battery replaced.

Fyi, .......

https://www.bannerbatterien.com/en/Battery-...board-batteries - EVERYTHING ABOUT THE 12V BATTERY IN THE E-CAR
EXPLAINED QUICKLY AND SIMPLY
.... Another Banner tip: Take the electric or hybrid car to the workshop for service or repair, then please leave at least one side window open in the workshop. Even better: leave a door propped open so that you can get back into the electric car if necessary. Why? Depending on the repair, the 12V starter and on-board battery could be disconnected. If this happens without external voltage maintenance, the doors could remain locked, depending on the car model! In the worst case, the workshop visit will now take a little longer than planned.

This information also applies to DIY (do it yourself) service and repair work. ...

Gemini AI Overview:

Disconnecting the 12V battery while an EV is running can cause various issues, but the car won't immediately stop. The 12V battery primarily powers the car's accessories, electronics, and some auxiliary systems, not the main traction battery that powers the motors.

However, disconnecting it can lead to:
- 1. Loss of Accessory Power: Features like lights, air conditioning, and radio may not function if the 12V battery is disconnected, as they rely on it for power.
- 2. Potential System Errors: Some electronic systems, like the car's computer, may malfunction or display error messages due to the lack of power from the 12V battery.
- 3. Difficulty Re-Starting the Car: The car may not start or have difficulty restarting if the 12V battery is completely depleted.

Important Note: The EV's main traction battery still powers the motors, so the car can continue to drive, albeit potentially with reduced functionality. However, disconnecting the 12V battery while the car is running is generally not recommended, and it's best to address any issues with the 12V battery when the car is off.

fuyoh not only green now purple somemore lol

Ayam glad my old petrol car dun have any high tech sensors that could malfunction at the wrong time and place.

Inaccurate. Repeating the same story and not recognizing parked and turn on scenario. Countered and explain many times before.

Also noticed I used the word alternator instead of DC/DC converter because I was referring to engine cars , they are powered by alternators not DC/DC converters.

When you are selling batteries, it's in their best interest to scare consumers to change their batteries every 6 months.

Just like another guy ifourtos or something like that, works as a solar system salesman, therefore constantly promoting the use of EV.

While running the alternator takes over. Only once you off , and the next time you try to start the car it becomes a problem.

China BYD defectife unit > export to Msia …

What are the potential consequences of disconnecting a car battery while the vehicle is running or without turning it off first?

Charles Tom Rauch
RF and Analog System Designer (1983–present)Author has 889 answers and 3M answer views, 1y

I designed charging systems and automotive electrical test equipment years ago. One should never disconnect a battery (assuming it is the only battery) from a running vehicle, here is why:

At a given drive speed, the magnetic field level in the field winding of an alternator or generator system is adjusted to produce a certain voltage at a certain load current. The field winding employs an iron core. That core, as well as the regulator circuitry, has response latency. It does not track the system output voltage instantly.

If the battery is being charged and the battery is suddenly disconnected, the alternator or generator output voltage will momentarily spike until the system readjusts to a lower magnetic flux level.

This spike can be anything from just a few volts to hundreds of volts, depending on pulley speed and the particular alternator system. If you are lucky and the spike is small, no harm will be done. If the system response is a little sluggish and the pulley speed is up, or the battery was taking a large charging current, the car’s electronics can be damaged.

There is also a second problem possible. If the alternator has a bad diode or other problems, the battery can sink and remove repeating voltage or polarity errors caused by the defect. The battery in effect smoothes or filters the problem down to acceptable levels. That safety is removed without a battery connected.

I understand people sometimes disconnect the battery with the engine running to either swap out a battery without resetting volatile memory in devices, or sometimes disconnect the battery to “test” if the alternator is operating (if the vehicle runs without a battery it means the alternator is doing something), but those are incredibly stupid things to do. One “can” do something stupid and get away with it 100 times, but the one time it costs a few thousand dollars for an ECU or nav system makes it not worth the risk.

The same should apply to EV cars.

that fella so kiamsiap one, using YES 5G but expect to get performance like fiber connection lulz
