The Lexus and Toyota hybrid batteries are tougher than common perception. For example, people are buying used HV batteries from junk yards that are sitting for a year and some are able to start their car after installation. However, it is a good practice to start the car once every month to charge the battery. It is more likely that the 12v battery will die first.

Another factor to consider is that as the HV batteries get older the less forgiving they are. A 18 year old Prius HV battery might be completely discharged in a couple of months while a 6 year old battery 300h might last up to a year.

Finally, Lexus and Toyota dealerships they have a HV battery charger and procedure to charge HV batteries but at that point some permanent degradation has occurred.

Not a single dealer in my area has one or even hinted the pack could be charged. Can you post a picture of the charger? I've read they exist but have never seen one. There are "rescue chargers" out there for hybrids don't know about cost.

It is called THS charger and the cost is like $8,000 so some Lexus or Toyota dealers might not have the tool.

No dealer here has that tool. To be fair Toyota hybrid batteries are very reliable (understatement). I can see why most shops swap them out instead of trying to revive them, even if you charge them up the pack could be end of life. My HyHi is currently being driven by a friend it has been excellent in bitter cold weather, great thing is since the engine is started via high voltage battery it has way more power vs. a 12 volt starting system.

On the downside if the 12 volt battery is low on charge the car won't operate.

That's every EV. When the LV battery prematurely failed on our 2020 Ioniq EV, it was stuck in the water. To get it up the tow truck bed, we had to jump it

So while my Prius sat for several months, when I would start it I would let it run enough to charge the battery by pressing the gas pedal to get the engine to fire which would charge the hybrid battery. Then sometimes I would let hybrid discharge then repeat. Or turn on the heat/AC so it would charge/discharge faster.

Came across what looks like a decent in-depth study of impact of cold weather on EV across a variety of models, plus range loss tips, etc

Stop being so defensive.

Cold weather affects range, it’s a well known fact that some people just won’t acknowledge nor accept. I’m not talking **** I’m not being mean, it just is what it is.

BTW I don’t care to pay $45 a tank for gas.

Whats the furthest you’ve driven on $15 charge?

My average cost of electricity is 0.17 cents a kWh, so for around $13 I can go roughly 260 miles with my driving style. I could probably push that to 280 miles if I use "Chill mode" and keep my speeds between 65 to 70 mph

not defensive, that was a fact. i'll stop posting facts when you stop making every post in this sub-forum a negative jab with no substance. deal?

recent contributions of yours...

indeed it does, and i don't care about those who won't acknowledge facts. as has been pointed out, gas cars lose range in very cold weather too. it just is what it is. i think everyone in here acknowledges it.

BTW I don’t care to pay $45 a tank for gas.
not sure what you mean. i wasn't referring to a whole tank of gas which typically costs more. my lc cost me $70 to fill this weekend.

so i pay 12c/kwh. thus $15 is 125kwh of charging and i get 3mi/kwh, so that's $15 for 375 mi. of driving. which i couldn't even do all at once because my battery isn't that big.

for a gas car, let's say $45 is 15 gallons of gas ($3). at say 27mpg (i know your phev does better), that's 405 miles so pretty similar.

so yeah, gas is 3x my ev cost.

your phev is great of course given the way you seem to be using it (lots of short trips and frequent recharging). you're basically using it as an ev with a small battery.

You're not posting any facts. It's not a jab. I didn't even post the friggin link about the reduced range. That wasn't even my data.




[/QUOTE]

So, am I wrong? Is it a good thing that EVs lose between 20-45% of range in freezing weather? I just said "that ain't good."

The "that sucks" part was me sympathizing with an owner for something frivolous that they were dealing with...

And excuse me for living, I was literally shocked that Rivian loses $440k per vehicle. Nearly half a million dollars????

It was zero and bitter bitter cold here for a week, my tank average wasn't off with the LX.

Our hybrids range is lower in colder temps because the engine runs more often. The PHEV was parked all week. I mainly drove the Prius. You are correct on how I use it. I charged the PHEV 2x at home today. It’s back on the charger again set to start charging around 5am.

In our LX, I want to say between 290ish on the low end and 320ish around town. Sometimes little over 330 but I think that’s pushing it. My wife DD it and she does a lot of idling and she has a led foot. Example EV range on the PHEV is 4 miles less after her driving it just 1 day.

In my experience no vehicle is as efficient in cold weather as it is in warm weather, hybrid or NA gas. In my tundras when it’s cold outside, it won’t shift into 6th gear until the engine/transmission is warm. I don’t let them warm up before driving.
