OMG - Drive-In movies! Didn't think there were any left? So now you have a low voltage trouble code is all it's saying not why just yet. A Chrysler product no less voltage is regulated by the PCM so suggest you rule out having a ruined battery from allowing it to get low on charge then ARE NOT ever meant to. Yup bet you used your radio to hear the movie was a huge mistake - don't do that again in anything. Use another device/radio find something but not use a vehicle's system.
Time to rule out things I'd begin with the battery properly charged up and checked for having ability to provide and pass a full load test.
Domino effect is if alternator is trying that hard to charge just a low battery it's getting way too hot and could fail itself from trying or further ruin now compromised battery not meant to be low like a "deep cycle" one not really used in vehicles.
1. Battery charged and known good.
2. Alternator checked off vehicle on this type.
3. Belt obviously known good.
?. Anything else about it - wiring or connections that were weak now burned or harmed.
You get down to possibly needing a lot of stuff and may have ruined the PCM - either the jump didn't go well or stressed that out?
Will need testing things out to know how much it will take. You should have a warning light on now and be experiencing low voltage when engine is running.
Know - if you needed a jump you instantly needed to charge that battery up with a charger not let the vehicle do that. Huge mistake done all the time on this could be VERY costly,

PCM is an abbreviation for Powertrain Control Module. That item includes the voltage regulation of alternator rather than inside alternator like most others! It's not fixable separately that I know of.
Pricey issues over actually bad luck or allowing battery and connections to get old and could still have problems just much less likely. Diagnosis is it's NOT any other reason so the testing is first.
What do you have to just check electrical things? Even basics, test light, DVOM and even a cheap but accurate voltmeter alone you can tell a lot. Cranking an engine can be used as the most load a battery would be exposed to for a short time shouldn't drop below about 9.5 and only for a short while if that low or battery is almost certainly going bad or bad.
They don't behave like so many things we let go dead and charge back up by size and cost needed are not generally used for vehicles. Don't let one go low and if so don't just jump it but even motor clubs just jump you and these can't take it nor much of anything and never could. It never was uncommon for an alternator to work so hard trying it got so hot the plug to it would melt. You must charge batteries with a charger. Jumping best left so you can just move it to where you can deal with the problem so choose towing instead if the issue happen by mistake or other surprise.
For my own am switching to Optima batteries that don't harm the battery but you still need a charger if used up they just tolerate it and meant to and cost a freaking fortune - ordinary good ones do too just double that or so!

The P0562 means the computer saw low voltage. Well, you already know you had a dead battery so the code is not a mystery.
Deal with you battery issues as tom advised and you should be fine.
