Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your Prius.These 3 codes listed are not related to the battery and are ones we see normally. The codes are all related. Have you made any repair attempts to fix these yet?
