Boosting with Kona?

My parents' car battery is dead...

I have a Kona EV and a clarity PHEV...
Can I boost the car using either one of these?
I don't even know if the batteries in the Kona ev are strong enough to start a gas engine

Probably not. The Kona battery is not meant to crank an engine.

In theory the high voltage battery has enough power and if it happens to charge the 12V when you do that it might work, but it's still questionable if that's a good idea.
 
I'm pretty sure the manual says you can't boost with the Kona since it's a smaller 12v battery. But the Kona can be boosted by another car.

The Kona appears to have a battery suited to a small ICE car with 410 "cold cranking amps" ability and 45 Ah capacity.
I see no reason why you can't use it to start a small ICE if you disconnect one of the terminals to ensure the Kona is not involved, but it's a risk otherwise.

From what I have seen most manufacturers specify not to do it including Tesla (could void warranty) and Nissan (couldn't find it in the Kona manual). But the following website says the following:

"...This could extend to unnecessary stress on the 12-volt battery, damage to the DC-to-DC converter, and confusion of the software that monitors the battery."

The battery might handle it (terminal disconnected) but then you have issues like resetting software configurations, windows and sunroof (if equipped).
Probably less hassle just to use a conventional battery charger on the ice, and avoid any problems with the Kona's 12 V recharging system after the depletion.
 
Portable jump-starters have been mentioned in other threads (which is where I learned of them), and they are brilliant. It's a comforting piece of kit that can be stashed in any compartment of the car.

The Kona system probably couldn't *boost* in the classic sense, but it could
very likely *charge* another battery especially as its rail sits at a pretty high
voltage relative to typical cars. A little patience should be able to get the
strandee going.

You might even be able to monitor things with some of the OBD2 tomfoolery
discussed here.
