Even if it is a different order of magnitude: I monitor my eScooter in the basement (outside it is just -2 DegC) with a simple 32x24 IR thermal imaging camera, or sensor, which would immediately report suspicious temperatures of the 835Wh battery pack - especially since I charge it unattended overnight. Occasionally you hear about eScooter batteries that start to burn in the garage.

Yes, I have the smaller „garden“ for the Pi Zero (2 W) for development purposes. Some are SPI, some I2C or both. And for the Pico. 👍

Electric Bike Review forum: Ebike Battery Safety: Storage and Charging at Home

"So without further ado here are some rules to follow to minimize your risk with batteries:

Read the owners manual and any caution stickers, and follow their requirements for safe charging.

Only charge your ebike batteries with the charger that was supplied originally with the bike or the battery. Create a process that includes clearly labeling chargers in your home or shop as to what goes with what. If you have chargers with the same connector but for different bikes (not uncommon), zip tie or stick-on a tag to those connectors that states what bike they are to be used with. Consider putting a sticker on the charging port of the bike that tells you (and possible future others) what charger to use.

Charge only in a dry location. Rain, standing water, etc. is bad for chargers.

Educate your family members, room mates and anyone who uses or borrows the bike on the safety rules and… which charger goes with which bike.

I like to use a wall-plug timer when charging – mine was intended to just control lights in the house initially, and I set it so that there is no power to the outlet during the night, and limits the length of time that the outlet is “on” to only 8 hours during the day time. This saves energy, saves me from moments of forgetfulness, and makes me look pretty professional to visitors.

Look over the place where you charge your bikes or batteries. If there was a fire… what would be nearby to add to the fire, or spread it? Charging next to your car means charging next to 15 gallons of gasoline which is much more dangerous than Lithium. Battery fires are hot, hard to extinguish, and generate toxic fumes and smoke. You are not going to be able to smother the fire, or pick up the burning battery and take it outside. So… choose a place that should a fire occur, damage will be minimized. I charge my bike on it’s kickstand, in the clear area of the garage a couple of meters from the wooden workbench, and a couple of meters from the car.

Install a smoke detector over your charging area.

Have a fire extinguisher located at the spot where you are going to be standing when you discover a fire. For example, hanging next tot he door from the house to the garage. Maybe a second one on the other side of the garage. Additionally, have a bucket that can be used to carry water to the fire – reasons explained below. Use a 5 lb. or larger ABC extinguisher, or a big CO2 extinguisher, or both.

If you charge batteries off the bike, I suggest doing so on a metal rack that has wheels on the bottom (very inexpensive at hardware stores) whith the battery(s), and chargers on the rack. In the event of smoke, bad smell, or fire, you can shove it out the door quickly. Locate it closest to a doorway that you can use to eject the battery easily, quickly and without coming in contact with the burning material or breathing the fumes. Consider how you would get a bike out the door. I have a boat hook that could be used to drag just about anything outside, and it is ~2 meters long.

In the event of a fire, evacuating the building is more important than fighting the fire. Calling the fire department (911) is essential. Keeping yourself safe and not breathing the fumes is more important than saving property. Even if the fire is safely moved outside, call 911, for these fires are tough to extinguish.

If you can get the fire outside, onto a driveway or other pavement, then you can consider extinguishing it yourself. To extinguish a battery fire, review this video on YouTube"

A bank of golf trundler batteries went up in smoke in a shed at my golf club. Luckily the damage was mostly just the batteries, chargers, shelving and the paint. If they had been charging in the clubhouse basement the smoke damage could have been enormous.

Just got the renewal docs for my model 3, and they have dropped the agreed value to $48,200 which IMO is absurd for a 1 year old car, so will have to start the go around with AA sending emails to them every time they email me saying to call them.

I suspect that was a hydrogen gas fire. There are commercial hydrogen detector, just for battery charging sheds.

Good ventilation from the roof would have probably prevented it also.

The Giltrap Group are holding an “EV Expo” at one of their Newmarket (Auckland) sites Wednesday to Friday, this week. I was invited, because of previous interest in some of their vehicles, particularly the Polestar 2, Enyaq iV and Born.

They had pretty much every BEV that the various arms of the Giltrap empire sell, from the eTronGT to the MG4. I thought there might have been some “Christmas Specials”, but (disappointingly) everything appeared to be the regular price. Since most of the vehicles were $80K plus there isn’t any imperative to get in before 31 December. It was interesting to see the various salepeople’s reaction when I suggested EVs were going to be a harder sell next year with no rebate and RUCs being applied.

They did have the new Lexus RZ there. It was very nice, but needs to be at $155K.

Great Wall Motors GWM Ora recall in NZ/AU

Newshub: Due to a programming issue, if the operator removes the charging cable without cancelling the charge, an electrical arc between the charging plug and the vehicle may occur," reads the Ora's recall notice issued on Monday.

and you have to take it back to the dealer for a software update because they are stuck 20 years in the past with their technology.

And how many car brands does this not apply to? My bet is very few.

Also, these aren't expensive cars so of course they'll be less likely to have over the air updates so as to keep the initial manufacturing/purchase price down.

One very good thing with cars that are always connected is the ability to push out updates quickly.

Tesla had some ABS issue a year or so ago that needed a 'recall' - by the time the recall was filed in the USA, a software patch had already long been issued that fixed the problem. So in many cases the idea of a traditional 'recall' can be eliminated (except where there is a physical component issue obviously).

I gather another advantage that Tesla has is that all the components they use are designed and built to their specs and all use the same APIs/coding language etc. That means they have great control over every part that can be software controlled. I think it was Ford (for example) that said because they buy in various units from different suppliers (like may other companies), they couldnt have the same degree of software control and update facility.

The flip-side is that the manufacturer can push out a bad update, "upgrade" you by removing or changing features you like and you rely on them to respect your privacy. That's why I hedge my bets with one Tesla and one MG.
