Notice the burnt EVSE mounted on the wall.
Of course the caption improperly identifies this as the lithium battery it is 
obvious it is the wall mounted EVSE.

Not true, the EVSE is supposed to limit the charging current to what is
safe to draw from the electrical connection.
For example, a 240V 30A circuit must be protected by the EVSE telling
the car that it can only draw 24A (80% of 30A) continuous.
The EVSE needs to select the proper duty cycle of the pilot signal to
convey this to the EV.
If a 30A circuit is attached to an EVSE that expects a 40A circuit, it
will tell the EV to draw up to 32A, overloading the circuit.

Besides a mis-match like that (which I have once encountered myself)
there are other concerns, such as a worn, damaged or corroded
contact in the charging plug, either of the EVSE or the car.
And then there is the ever-present danger of a failing wire in the cord.
This is not exclusively a problem from EV and EVSE, as my colleague had
a small fire in his house this last winter
due to the wire at the back of the wall plug starting to break
internally and the remaining strands overheated to the point 
of setting the cord on fire.

I have had similar experience with an outlet in a previous home, where
the wire coming out of the wall probably was nicked
before being attached, so after successfully washing loads of laundry
for years (water was heated electrically so the washer
drew about 12 Amps continuously for an hour or so during a hot wash
cycle) suddenly one day the bathroom filled with smoke
and the wire inside the outlet burned clean through.
There had been no movement of that wire, so no gradual breakage - this
was purely a resistive heating induced failure.

Besides the EVSE itself, the circuit it is fed with and the charging
plug contacts,
also the circuitry inside the car (AC powered HV battery charger) can
fail, for example an improperly tightened wire
or a loss of water cooling overheating the charger, which subsequently
fails and burns...
So many different ways to let the magic smoke out...

What does the EVSE have to do with this?  The car makes the decisions.
The EVSE is just a super safe power cord.

 then at the end I placed some image links of Smart EV frames without
their body.

The EV's body was not metal and completely bunt away. Only the metal
frame was left, including the metal frame for the doors. Compare, and
decide. Was this EV really a Smart? Or was it something else.
