Charging fire safety e bikes
Re: Increasing risk of fire and danger to lives
Just a thought. When are wexsupposed to charge these things? If they are in use during the day then over night is the answer. Cars especially.

Re: Increasing risk of fire and danger to lives
I can't disagree with any of the above, I just find it a little annoying that what should be a general quality and product regulation issue becomes hidden by blaming a technology and implementation. But even if is just perception that e-scooters are a high risk I can see it would be hard not to want to be seen to mitigate that risk.AndyK wrote: ↑29 May 2023, 11:38pmI read a report in the BikeBiz trade mag a few months back on this - it's online at https://micromobilitybiz.com/fire-safet ... ty-market/ . Obviously it's seen through the eyes of of "reputable" UK e-scooter dealers and distributors, who can't compete on price with untested, uncertified and unregulated grey imports, but it's an interesting read anyway.
My (wholly evidence-free) theory is that e-scooters are seen as higher risk because e-scooter fires are more common than e-bike fires, in turn because e-bikes are mostly bought by older people who are more likely to pay a premium for a well-known brand from an established dealer and more likely to pay for regular maintenance, while e-scooters are mostly ridden by younger people with fewer qualms about finding the cheapest price they can, buying direct from made-up-company-name in China via AliExpress and accepting that they'll ride it until it turns into a ball of flame, then buy another one.

Phew! How complicated chemistry appears to be... a point I made to my science teacher, as a teenager, but with which he seemed to disagree!

Re: Increasing risk of fire and danger to lives
Hi I'm new to the forum and have an ebike on the way.
The battery is supposed to be from one of the more trusted brand names but I'm not taking any chances.
The Barbi died so it can charge out there. A lot could go wrong from putting your battery to charge in such a place unless your Barbi is dead and you have no gas bottle there. One could trip on the extension cord I suppose. This is obviously not advice for others just what I'm doing until I think of a better way.
Cheers

Re: Increasing risk of fire and danger to lives
what will you do in the winter - charging the battery in sub zero temperatures is bad?

Available from places that sell parts for model aircraft/other powered models. For example: https://wheelspinmodels.co.uk/m/622/
I have a couple of medium ones because I have quite an inventory of basic non-intelligent Lipo cells (the model type that need a proper charger and balance boards) for models. It's not unusual to crash models, and they use multi-cell packs that need balanced cell charging, so I treat the model packs with a bit more TLC than the usual consumer gadgets with Lipos in.

Re: Increasing risk of fire and danger to lives
I would imagine there are far more visits to A&E generated by trips over extension cords and far more fires caused by BBQ activities, than there are related to appliance batteries. As I have said up thread, the few incidents involving lithium batteries vs the number of same in daily use is insignificant. I believe much of the perceived problem is typical media scaremongering.Therealgoodguy wrote: ↑4 Jun 2023, 10:52am Hi I'm new to the forum and have an ebike on the way.

The paper from the research among other areas looks at the risk over the life cycle of the cell.
https://www.sciencedirect.com/science/a ... via%3Dihub
The data that I'd like would include how many incidents have a putative proximate cause of the type that everyone suspects: voodoo wiring, damaged gear, untraceable imports etc. That might reveal the risk for reputable kit used as recommended.

Re: Increasing risk of fire and danger to lives
"Deputy Commissioner of London’s Fire Brigade Dom Ellis said that the force had been called out to 58 e-bike fires and 14 involving e-scooters this year, which “works out at roughly one fire involving these types of vehicles every couple of days.”
“As such, we have identified that fires involving lithium batteries are the fastest growing fire risk in the capital,”"

Re: Increasing risk of fire and danger to lives
Fire risk comparison from an insurance company here, it seems pretty inconclusive.
Fires per 100k sales:
Hybrid: 3474
Petrol: 1530
EV: 25
Fire safety recalls were all battery related on the EVs, not wiring.
But then further down the page:
"electric car fires occur in 3 out of every 1,000 starts, while gas car fires occur in 1 out of every 10,000 starts"
and
"electric car fires are responsible for approximately one-third of all car fires in the United States"

They don't appear to have any aperture for the charger cable.

Thanks for that. It's a weird article with those personal stories, but it does have some useful data at the top.axel_knutt wrote: ↑25 Jun 2023, 5:18pm Fire risk comparison from an insurance company here, it seems pretty inconclusive.

Re: Increasing risk of fire and danger to lives
This fire risk stuff is very disconcerting!
I have been saving for and working towards e assistance. To be worthwhile I had assumed using full charge nearly everyday and charging in garage overnight. Sharing with a car and full tank of petrol seemingly not a good idea! Garage also contains large batteries for the solar roof panels.
Charging overnight looks a no-no in the house.
Maybe e bike not as practical as I had thought?
