You will need to provide a lot more information to get an answer.
Draw the full schematic. Give full details of the drive signal. Give the part number of the mosfet. AND what do you require it to do ?

High side gate drive.... Drain connected to input of 22.05V,source connected to a 12 V battery..... Switch should close when charging battery and open when the battery is full .

No it doesn't work.
The opto will drive the gate to 22.05V, the source will be about 3V lower than this (19V). Lots of current will flow and things will blow up.
