Do Electric vehicles have deep cycle starter batteries or "house" batteries?

[lustyd]

I watched a video of a teardown of a Tesla 80kW battery. It was indeed 18650 single cells in banks. It had a liquid cooling system. Wonder if that's used for heating in cold weather?

Yes they can warm the fluid with the brakes and motors apparently through heat exchangers as well as the other way around. The cells connect with essentially a fuse wire so if one fails it burns itself out of the battery and everything carries on. Very interesting stuff to read about, albeit a nightmare for fixing. Apparently easy to recycle though.

The ioniq drive battery has active air cooling, which enters the cabin.

How do you keep warm in a electric car ?

my 5 year old Nissan Leaf has a heat pump which I think helps with heating, but also helps keep the bigbattery cooler if doing multiple rapid charges if on a long drive/stopping off at service stations etc to top up. But we've no problems being warm in our car and can set it to come on early and warm up on cold days if we wanted by app/timer (we used to do that, but haven't bothered in recent years) - but that can melt any ice on windows etc while still plugged into the home charger so not really loose any charge

its also got a usual lead acid battery for things like the wipers, windows, locking, radio etc and a 30kw battery for propulsion

glad to say done over 70,000 miles in it so far - all drama free and been all over the UK and the battery capacity is still really good (hasn't lost one of its charging bars as yet which some of them have done)

Fit a chinaspacher if you don't want reduced range in cold weather.

Or a really environmentally friendly solution

Most of us have two kinds of batteries on our boats, one (set) to start the engine, and one (set) to run nav lights, fridges and stuff.

As I cannot find an answer in the electric car world, I thought i'd ask here:

Do electric vehicles have a plain starter battery (to supply high current in short bursts) or do they indeed have deep cycle batteries to run the 12 volt system?

I'm asking because my Hyundai Ioniq ev went berserk when starting after the first cold night but started just fine after a little wait plus having the 12 volt battery being connected to a booster pack.

Since Hyundai seem unable or unwilling to answer this, I thought I'd ask around where people are actually accustomed to the two kinds of batteries ; )

They have the cheapest 12v battery they can find. No high current requirement so a deep cycle would be the best replacement when it fails.

Use the heating (and reduce your range accordingly). Significant impact this time of year.

Virtually no impact if you have a heat pump. Some cars stupidly have resistive heating though. Heating on full makes 2 or 3 miles difference on my car. A cold battery makes a huge difference though, but don’t think that’s the heating and sit in the cold.

Not true. It’s the cold battery that makes the range difference not the heating.

What powers the heat pump? Not much heat available here just now, with temperatures way down below zero.

The traction battery. As I said turning it on and off makes little difference and the inside of the car is toasty.

All EVs (that I know of) have a starter battery, just like an ice car. This powers up the door unlocking and a host of other ‘house’ functions...

It seems Tesla didn't think through the consequences of a flat lead acid battery, (perhaps in earlier cars than yours). What's wrong with a key that can open the door and a cable located inside to release the bonnet under which the lead acid battery is located?

My car has the lead acid battery which, as we all know, can fail at anytime...it is not upgradable to a lithium battery because that has a higher voltage. What they have fitted (more or less what James May did) is a secret opening with connectors in so you can recharge the battery without opening the hood.
I think what nobody accounted for was a sudden really long draconian lockdown. But anyone with a car, or boat, knows that the starter battery is your Achilles heal

This is true. It seems Tesla did not know that.
My wifes petrol car starter battery failed due to lack of use in 2020 .
But the design allowed the bonent to be opened

Anyone with auto locking doors would have trouble opening the hood...I did learn many years ago that if you turn a bmw key backwards it overcame the problem and manually opened the door...mind you it was the AA man who showed me...so not actually helpful at the time?‍?

The aux battery must not be forgotten - needs to be charged and happy,

Well a starting handle on a marine engine is a mighty handy thing..

I could just about imagine the inventive Janes May devising and fitting a wind up battery generator and handle in the front of a Tesla —and his sarky mates falling about watching him wind it round long and fast enough to get a charge in the starter battery ..

Of course, if you haven’t got a 250 mile journey you just run the bloody heater, the seats and the steering wheel, and do the journey in your pants, no problem.

Plug in trickle charger is the answer there. My Morgan inevitably spends relatively long periods in the garage unused. After a couple of weeks without use I plug in the charger. Just had to replace the battery after over 19 years from new! 26Ah Red Flash and replaced with the same. Of course no problem opening the bonnet or the doors!
