Does anyone tried to decode serial communication between prius V lithium-ion battery and hybrid ECU?
"The battery smart unit converts the HV battery condition signals (voltage, current, and temperature), which are needed to determine the charging or discharging values that are calculated by the hybrid vehicle control ECU into digital signals, and transmits them to the hybrid vehicle control ECU via serial communication."

A delve into the wiring diagrams should tell you what kind of communication it is, and it can be decoded from there in a live car.
