The more powerful the battery the more likely this is to happen because the more likely they are to have them on fast charge.

The issue of eBike safety is something I raised in a meeting on
Thursday. It was a proposed new housing project in my city. This was
part of the "Environmental Review Committee" on which I serve as chair
of my city's Planning Commission. A developer proposed giving every new
resident an eBike in order to get the project's "VMT" (vehicle miles
traveled) down to the required level.

When I asked "where would these eBikes be stored and charged?" the staff
said that for the rental apartments they would be brought into the
housing unit to be charged, which I thought was a particularly bad idea.
I would want a secure enclosed parking area with fireproof walls and a
fire suppression system.

Apple, and presumably other good brands of phone manufacturers, used to supply a quality charger (albeit Chinese made) with every phone. Now they've got a case of the cheapies and don't supply a charger any more. Therefore the fires-from-cheap-Chinese-chargers is likely to get worse before it gets better.

The power supply that came with my 12.9in iPad Pro in 2020 was obsolete for my modest use the moment it came out of the box, and was relegated to powering less puissant devices in different places and functions where they would be used alone. I bet most people with hubs underpowered the devices plugged in, increasing the fire risk.

I’m not sure if that is a fair comparison. My phone will sit perfectly
happy forever connected to any charger that puts out a nominal 5V because
the charge controller is inside the phone, so for the most part, if my
phone bursts into flame it’s Apple’s fault. However, I don’t know where the
charge controllers for eBikes sit. Are they in the charger or in the
battery pack? If they’re in the charger, then a bad charger is very bad
news indeed, but it it’s in the battery pack, then the quality of the
battery pack is of greater importance.

I don't know about there but here we have had phones being set on fire from those chargers. My A21 got really hot a couple of time so that I wouldn't put it on the fast chargers. And after it got hot like that it went flat very rapidly. My new A22 is the small size and it runs completely flat by the end of the day so I have to be careful with the charge.

My A22 Android will NOT charge on anything other than a fast charger.

The control electronics have been inside the battery in both the electric bike batteries I have owned. It's a particular selling point of quality battery packs, and a good reason for consumers not to attempt to build their own battery packs. -- AJ

Well... certainly phone chargers are cheap; (:-) But in mitigation
I've been using hand phone chargers for as long as there have been
pocket size phones and have yet to have a charger break into flames or
explode.
And I currently have one that powers a "night light" that has been on,
continuously, 24 hours a day, for several months (:-)

The hazard must be much smaller with cell phones. Battery capacity is
tremendously smaller, charging current is probably much lower, and if
the phone did begin to blaze, once can probably scoop up a phone and
toss it outside. I'm sure that's much harder with a flaming 75 pound bike.

I've been using "hand phones" since they first became "pocket size"
and in that period I have had two "battery failures". In both cases
the battery simply swelled until the back of the phone case wouldn't
close, or popped loose in the case of more modern phones.

In fact, if memory serves, I've had more phones repaired due to loose
charger sockets then for bad batteries.

Executive summary for Andre: Most fires are caused by defective
batteries. BMS and charge controllers will protect batteries. There
are unfortunately some poorly built cells and batteries in
circulation. eBike and smartphone batteries are very different.
Laptop batteries are closer to eBike batteries than to smartphone
batteries.

Any decent LiIon or LiFePO4 eBike battery will have an internal BMS
(battery management system). There are a few that have a built in
Charge Controller. The purpose of the BMS it to prevent battery
overcharge, undervoltage, overload (excessive discharge),
overtemperature, undertemperature, and balances the individual cell
voltages. Any of these can kill or damage a LiIon or LiFePO4 battery.

The BMS will not prevent a fire. If it detects too high a cell
temperature, it's too late. The battery is probably already hot
enough to start a fire. The usual cause of a battery fire is internal
to each cell, where the separator is punctured or shorted, causing the
battery to unload its store energy inside the cell. If there's enough
energy, there will be a fire.

External to the battery is a charge controller also known as a battery
charger. It's purpose is to supply sufficient power to charge the
battery in a manner (charge profile) that doesn't also kill the
battery or start a fire. It is possible for a charge controller to
dump enough energy into the battery to get it hot, but the BMS will
detect the overcharging and disconnect the battery long before a fire
can start.

There are batteries that contain both a BMS and a charge controller. I
have a few of these (Bioenno Power BLF-1220A) for use in radio
systems. This battery will not power an eBike or a smartphone:
<https://www.bioennopower.com/products/12v-20ah-lfp-battery-pvc-blf-1220a>
Notice that there are two pairs of leads. One pair for discharge, and
one pair for charging.

Smartphone chargers are very different. All smartphones contain a BMS
and charge controller. The BMS does all the things mentioned for an
eBike. However, because a smartphone runs on a single cell 3.7VDC
nominal voltage, there's no need for a cell balancing charging
feature.

The internal smartphone charge controller decides how fast and how
much the phone should charge using an assortment of standards such as
USB, Power Delivery, Quick Charge, and some other oddities. Each of
these requires a matching charger that supports USB, PD or QC charging
at various levels. The original USB charger would only deliver
0.5Amps (2.5watts) at 5V. Some of the latest fast chargers will
deliver 60 watts. To prevent the charger cable from melting or
fusing, PD and QC increase the voltage to the phone. Inside the
phone, the charge controllers converts this down to the 3.7VDC used by
the battery. If the charger somehow manages to increase the voltage
and shove all the current into the phone, and both the charge
controller and BMS fail to notice the problem, the power cable will
probably fuse and prevent a fire. Smartphone fires start much the
same way as eBike battery fires. The separator in a cell is somehow
shorted, unloading all the stored energy into the cell.

You new Samsung A22 has 5000 ma-hr battery. That's about as big a
battery as vendors are currently supplying. My Moto G Power (2020)
phone also has a 5000 ma-hr battery. One days use will take me from
about 95% to 75% SoC (State of Charge). Two days to 55% and 3 days to
35%.

So, why does your phone run the battery down? Checklist:

The Samsung A22 5G only supports USB Power Deliver 3.0 (PD3) to 25
watts. It does not support Qualcomm Quick Charge 3.0 (QC3).

As to why your phone will not charge on a conventional USB charger,
the usual problem is a 12.5 watt (5V/2.5amp) USB only charger and a
really thin USB-C cable. The cable resistance is too high for the
2.5A current, so the voltage at the phone drops well below 5.0V. Try
a USB-C cable with heavier wire or one that is rated for the higher
power chargers.

I'm in no hurry to kill my phone battery. So, I slow charge my Moto G
Power (2020) with an old USB 1.2 amp (6 watt) charger overnight. It
takes about 5 hrs to charge, but it's also not likely to kill the
battery. After about 2 years of use, the battery still has 95% (4,676
ma-hr) of the design capacity (5,000 ma-hr). If I'm in a rush, I have
several 18w and 30w chargers that will bring it up to 80% SoC in a few
minutes.

In spite of the fact that it seldom gets below 90%, I plug my Iphone
12 every night in to the charger that came with it. I do carry it on
my bike rides and I started leaving it turned on recently due to my
wife's desire to keep informed of my riding progress through a Garmin
app she discovered. It, however is silenced so as not to disturb my
ride. Fact is that it's almost always silenced. I may feel it vibrate
in my pocket or my watch will vibrate, but way more often than not,
calls go to voice mail.

I suspect some of this is the very cheap E things be they scooters or
bikes, mobile phones have a different issue in that small area to dissipate
heat, which is why the Samsung note 7 caught on fire.

Some friends have E MTB and give impression of a quality product, as it
should be, for 5k+!

The cheap hacked on, and so on bikes I see nr work which is a deprived area
are not!

A single-cell Li-Ion battery, charging at low-current, is unlikely to go
into thermal runaway and start a fire. The device has protection
circuitry built in that prevents crappy chargers from causing a fire.

It's a lot different when you have a 16 cell battery and a high-voltage,
high-current charger.
