  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

Lithium Battery Technology

For my environment, @Darren is dead on. Most of my trips are 60km round trip or less, but I don’t want to lose the ability to go for longer distances when needed. BOBW.

Just my opinion as a factory trained hybrid/EV technician is that the only one's that make sense for our climate and infrastructure are PHEV's. Go all day on a charge, can charge itself when it needs to without leaving you stranded, and can be plugged in at night on a timer. The batteries are much smaller of course but for short trips like 90% of people mostly do, they have good capacity.

So like a Prius v.s. a full EV?
 
A couple of years back when we had that heat dome out here in BC I had just finished reading this book "The Ministry for the Future" by SciFi novelist Kim Stanley Robinson. This was just before the Ukraine invasion too.

In it things like carbon from ships, the wealthy in their private jets, wage disparity are all discussed. And it started out with a heat dome in India that killed a lot of people.

Just my opinion as a fellow who did automotive R&D for his career.

You are right on for most people in Canada wanting to strike a good balance. Your advice would be my advice too.

That doesn't mean I don't support the idea of a regular combustion engine or a 100%EV. They all have their place. Depends where you live, what your driving patterns are, and how much cash is in your bank account.

My personal opinion is that we can and should make our own choices that suit our own needs and wants.

Where I get all bent out shape is when some movie star or politician tells me what I have to drive and plays games with my choices by subsidizing and taxing them, all while flying around the world in a private jet or mega yacht.

I want to buy, drive, and refuel what makes sense for me in my own circumstances and I hate it when I'm told what that has to be or forced to make choices that are biased by market interventions that only apply to me and not to the guy ramming it down my throat.
 
A few more of us that are able, should walk a block or 2 instead of driving. the cost of warming up a car/?, deicing the windshield, Before driving it can be more then the cost of useage to go the short distance.
I recall a young person coming to North America by sail boat instead of flying, however the cost of the high end sail boat energy wise is not cheap and was not taken into account.
People want the newest,latest, greatest cell phone or lap top/computer every year. I really can't find the different between 3G and 5G, other then 2. And it's nice to find new ways to fight with the latest upgrades that I don't need any of in the first place.
Mass transportion is far cheaper then single transport, just everyone needs to want to go the same place, at the same time.
I am not sure how a electric economy can work for food production, but that is one of many things not to my knowledge.
A mix of ways to move and power is the possible way forward, maybe the only way ahead.
Some of the problem with the engines is how much power does it take to move a set distance, how fast to do it, and how much fuel/energy to do it. Many engines use a lot of fuel to do very little.
It was interesting to read about making different types of fuel from CO2., some I was awear of.
Some time ago, I looked into high mileage cars, 80-100 mile per gallon available in Europe, not brought into North America as there was no demand for them, tell you anything?
Yes, the amount of cash is going to control what can power your world and if you can eat or not.
I also am very tired of people that have never done much( anything) complaining about how the world is and how it should be fixed by everyone but them and how "it's" owed to them and they should be given all.
Time for me to stop!

Spoke to an old colleague of mine who owns a Tesla and was involved in a Lithium Battery project. The Valence system we used had a BMS that would not close the main power contactor below about -20C and wouldn't allow charging below 0C. To start up that sort of system means the batteries have to be heated until they hit -20C. At that point you can discharge them. Our system had several ways to warm up the batteries when it was cold.

He believes the Tesla's use their heat pump technology to keep the batteries warm enough to use even when the car is sitting in the driveway overnight. So when you get into it the batteries are ready to go. Of course if it's plugged in not an issue.

Anyone with a Tesla or other electric car know anything about that?
 
Hyundai has "winter mode" that will turn on the battery heater when the car thinks it needs it. When it turns on is up for debate as there doesn't seem to be a definitive answer in the manual or on the forums.

Must be information that is protected from corporate espionage.
 
That is something else that isn't explained, the Ioniq 5 has both heat pump and resistive heating but when/how which is used again is not explained.

For those of us living in what I call "EV Eden" it's not really an issue, less for us as the car takes up space in my heated shop.

Blasphemy!!!! A car inside a shop? Don't you know the rules? A shop/garage is not for cars. They have to drive around outside so they can darn well live out there too.
Just shocked! A car inside the shop. Sigh....
