Hi, The IMA light is on and I am getting P0AE1. To fix this problem will I need to change the inverter, relay or what should I test?

I got the car and I took off the back trunk cover and got access to the battery case.
Some part of the battery case is rusty. I took off the switch cover and the switch was in the off position.
I turn the switch on and the ima light came off and the 12v battery started to charge. I scanned the car and reset the code and the P0AE1 came back. So I am guessing something in the battery assembly is failing which I will test.

No codes after doing the 12v battery reset. I'm guessing a mechanic turned the switch off. The person who I bought it from said the Ima light was on and the 12v battery died. I don't see anything wrong it's now charging the 12v battery after I turned the switch on. Should I do a voltage test of the hybrid battery?

I charged the battery for 24hours with the cooling fan on. I waited 2 hours to start the car and my generic obd2 scanner showed 196.5F for the IMA Battery Temperature.
Before I charged the battery my generic obd2 scanner showed 167.4F.
Should I be concerned?

I don't know if it is showing the right data. It also shows 75% soc.
I look at another previous data before grid charging and it shows 206F.
If it was that hot wouldn't my check engine light or IMA light come on?
I don't have any codes other than ABS which my scanner can not read.
