Answer by AI:

Why the DC-DC converter isn't always on:

1. Efficiency and Energy Conservation:
The converter consumes power even when idling. By turning it off when not needed, energy is saved, which translates to increased driving range.

2. Overload Protection:
The converter needs to manage the flow of electricity to various components in the car. By turning it off, potential overloads are avoided.

3. Thermal Management:
The converter can generate heat, especially during heavy loads. By turning it off when not actively needed, the risk of overheating is reduced.

4. Wear and Tear:
Constant operation can wear out the components of the DC-to-DC converter, especially the switching transistors.

5. Control and Communication:
The DC-to-DC converter is often controlled by a vehicle's onboard computer, which monitors various parameters (voltage, current, temperature, etc.) and determines when to turn it on or off.

.
Also, "Power System Failure" that shuts all power to the EV car, can also result from issues with the high voltage system or traction battery.

How ?

how did they manage to MOVE the (seemingly unmovable) EV onto the tow truck?
from what i read...
"Because of the complications that come with the absence of a neutral gear in an electric car, the only way to tow an EV is with a flatbed tow truck."
doesn't go on to explain further about neutral gear or how to get the car out of the locked tires scenario
presume there's a method to switch the drivetrain from locked to free to enable the EV to be....pulled i guess onto the flatbed tow truck

See the FB pic la.

perhaps you're good at deciphering techniques from an image

not me

errors lit up like christmas tree LEL

To make it short, Tow truck have all the design and equipment that can tow any car situation.

Picture tells a thousand words.

tau laa...tow truck got all all (but actually no also)

how to FREE (neutral) the ev is what i'm tryin to get at
as to whether manually (without power) can make certain settings on the vehicle to make it movable - doubt this
or
they brought some form of auxiliary power supply to power up the EV to make it move

bruh... almost sound like the annoying fry machine in mcd

Main battery hangkang? Later come many pattern not to huashit honor battery warranty Liao. Ceri already did that sueying the driver for failing brake and failing axle

So, what's the real issue? BYD or user problem?

auto brake because of regenerative braking kot.
question is why the driving system depends on 12v battery? if the voltage is too low, it should at least prompt the user, complain charge system failure or some shit. takkan la takda voltage sensor on those low power system?

Who knows for sure, perhaps there were prompts but the user ignored it. That's our standard la, even cardiologist have done it before, ignore aje warning tu, balik rumah tengok YouTube Cuba settle sendiri. LOL

I am guessin it's user problem. Kejap no, what I am saying is user problem failing to understand fully the terms and conditions of the 12V battery.

But let's wait for BYD official statement on this matter before I tighten the screws further.

like all EV got problem ma? tesla also same

Ever heard of wheel dollies?

tesla already changed their battery to llithium based one.

however downside moving to lithium battery, the accessibility of those battery will be bad if the battery failed, only official service center can help. it will only make sense if the distributor have service center in every town out there.
