An E Bike caught fire this week whilst being charged. This guide is worth a read.

My main e bike has a 48 watt Samsung battery the portable bike Taiwan. I suspect the owners of the fire damaged one left it charging too long.
Overcharging is becoming a main cause of the fires according to what I read rather than say spontaneous combustion.

It is easy to forget when the battery was plugged in, but still should not overcharge. We leave the battery for our lawnmower plugged in 24/7 365 days and so far no issues. Lithium batteries sit in caravan 24/7 365 being constantly charged via the solar panels so not sure why some burst into flames?

All our EV chargers are fan air cooled. The instruction say not to fully charge. Strange as the chargers switch off I think when the battery is 100% charged.
The E bike at 100% shows 52 volts even though the battery is 48v. Maybe I’m over charging?

I suspect those batteries that ignite whilst on charge are primarily associated with cheap imported goods, and not from a reputable supplier. I charge power tool batteries in the garage but they tend to get switched off within a couple of hours. Things like phones, tablets etc are charged in doors all with reputable supplier chargers and cables, but they are switched off if we go out, and when going to bed.

I am sure there is a lot of security in buying trusted named products.

However, this did happen!

Bosch E bike batteries are made in Hungary. Samsung South Korea and US ,and Panasonic Dalian China.
Bafang a popular diy E bike battery is made in a number of European countries plus US and China.
The ones to avoid I am told are those made in Indonesia. Allegedly those batteries don’t contain over charging protection mechanisms leaving them vulnerable to ignition.

The lesson for me is don’t over charge. Don’t leave charger on when out.

There was another one regarding a Tesla car which burst into flames. The electronics then failed and the people inside the car were not able to open the doors and escape. Unfortunately they burnt to death.

True, many of us leave our laptops on charge 24/7 with no problem.
