2012 Prius seeking guidance re post repair codes

I have a 2012 Prius (230,000 miles) that had a bunch of codes including hybrid system...pull over in a safe place and coolant pump codes. I replaced the coolant pump (old one had a fractured impeller). I replaced coolant. When it would not start, I had the starter battery checked and it was bad so I replaced it. It started and ran fine for a few hours. I drove it a couple of miles. Soon after this, the hybrid system light came back on, engine light, Red triangle. It would still drive but I did not want to chance it. I rechecked codes and it had Po455/P2618, P0A80 and Pob3d.
I don't know what to do at this point. The General Evap System codes I can probably figure out. Funny that none of those came on before and I did not touch the eval system during the previous repairs. The coolant pump B control circuit perf stuck is one ZI'm not sure about.
Replace hybrid/ev Batt pack and hybrid/ev battery voltage sense A circuit low......What do these mean? Do they really mean the battery pack needs replacement?

Any help on any of these would be great. Thanks

 

Thank you very much for your reply. I did not save the previous codes however most of them related to the engine coolant pump which I replaced. The one code I remember was the "hybrid system...pull over in a safe place" code and the car went into limp mode. It finally would not drive any more so I had it towed to my house.
After replacing the engine coolant pump, the coolant and the starter battery, all the codes disappeared for a brief time and it started normally and drove normally. Then it would not start for a short period of time. When it started after a week sitting, the hybrid system warning came on with a triangle and check engine light. I then checked the codes again and that's what I posted as codes (all current). The P2618 I'm pretty sure ends with 8 rather than B but I will double check. I will check the orange connector at the battery smart unit. I assume it's right there with the new battery I replaced.
