Not been a good time for batteries recently.

Those trays of batteries (18650?) Started going off like firecrackers, and it all happened so quickly.

Yeah, and they kept going even after staff (bravely) separated out the burning trays.

I've got a tray of those 3.7v batteries sitting between my legs on my ebike, first hint of smoke from it and I'll be off and running. I already charge it in the front garden 'just in case'.

 

No so worried about the house 3.2v lifepo4 battery pack sitting in my kitchen.

So much for E vehicles.

 

Glad I never bought into that fad.

You are concerned about e-vehicles?

They are relatively safe by which I mean they are now all LiFePO4 powered. Thermal runaway starts at about 250^oC internal temperature.

Power tools on the other hand are NMC powered (NMC is a type of lithium battery) and the thermal runaway temperature is in the region of 170^o C

How many cordless power tools do you have?

 

We don't know what type of batteries were in the container but power tool batteries are all over the place.

We need a photo of an MG-EV and the statement that ICE vehicles catch fire more often than EV's... 

 

If only someone on the forum had such information to provide us with...

Change what?  No reason for me to own a car in Pattaya.  It’s a hindrance.  My Vespa takes care of my transportation needs here.

 

However next week I’ll be back home enjoying the California sunshine in my convertible.  Gasoline powered!  
 

Perth must be getting cooler this time of year.  Do you have heat?

Perth, no idea about the climate there, let us know when you get back.........🤭

Fine, if you only plan on hanging around the area and not going anywhere else. 

Suppose you could rent for further journeys.

Nice...  Thailand is just too hot for a convertible...    that said, its also too hot for a motorcycle if we are thinking comfort.

The good thing about power tool batteries is that they are at least (often, always?) protected against physical damage.

I am sure I can throw my Bosch power tool batteries against the walls or floor and the battery cells won't be damaged.

Would point out the exploding batteries were sitting in trays in the factory, not being charged and undamaged.

“charge it “. Ok, got me.  Regardless, I would never own an EV.

Accompanied by colourful language too I expect because something didn't go quite according to plan.

Physical damage of that nature rarely causes harm (to the battery).

The problem is internal within the battery.

If you are interested you might like to Google up "dendrites".

They are the enemy but not the only one.

Indeed..

[Muhendis]

Well done Ben.

Perhaps I should clarify that since we are talking of batteries, the dendrites are also battery related.
