Also, a well-designed EV can park almost indefinitely with no maintenance, because the big battery keeps the 12V battery charged.

That doesn't work on a hybrid, because the big battery is often drained during normal operation, and you have to worry about the fuel going stale.

Is long parking time an interesting stat for cars? Anyone I know parking a car for a long time it’s a 4th or 5th car and there are tons of cheap solutions for it.

Agreed, it’s a weird flex

Depends on the owner's usage patterns... I don't want to be the "television is no friend of mine" guy, but I look forward to a future when jumper cables are basically obsolete.

Lithium ion jumper batteries have already made them obsolete.

Wait, what? I just jumped my car yesterday with cables. What is a lithium ion jumper battery? Is that something in newer cars?

Well, it isn't an integral part of the cars or anything. It is basically a chonky powerbank that can jumpstart a car.

It's exactly like having a separate car battery and jumper cables. Except with a relatively small lithium-ion battery bank rather than a traditional car battery.

Sure, if it hasn't been sitting in your trunk for 6 months and all the charge leaked down.

BEV for such rarely used car is wasting energy and materials. ICE is best option for such use.

I don't know on a full EV, but i know my PHEV has a relay for the big battery. When the car is off, the big battery is disconnected, and the 12v will drain (and would tend to die). I had to jump it a couple times, it just needs enough power to get the relay closed, the big battery usually has enough to run the car and start the engine as needed from there. Would have been nice if they didn't bury the 12v in the trunk, underneath the big battery though.

Not true.

a) the Volt keeps about 10% battery charge unavailable for driving. To help maintain the battery and also for the purpose you mention.

b) the Volt keeps track of when you last ran the ICE, and runs it every few months on a "maintenance cycle" to keep the fuel and fuel system from going stale
