When a OBD2 code [P0A80](/p0a80-prius-code-means-replace-hybrid-battery-pack/) is read / stored in system, it means that the ECM has detected a malfunction in the hybrid vehicle battery management system (HVBMS). This code indicates that a cell has gone weak in the hybrid battery pack. Hybrid vehicles (which do not require external charging) utilize nickel metal-hydride battery packs. Battery packs are actually blocks of batteries (modules) that are wired together using sections of connectors or cables. The typical HV battery is composed of eight (1.2-volt) cells in series. Twenty-eight modules make up the typical HV battery pack.  
The voltages are from 205VDC to 236VDC between the inverter and the power extractors, safety measures must be taken to avoid permanent damage or injury to the persons performing work on HV car.
