DTC P0A94-587 DC / DC Converter Performance: Description
See the description of the boost converter (see DTC P0A94-442 DC / DC CONVERTER PERFORMANCE ).
The HV control ECU uses two voltage sensors, VL and VB, to detect voltage levels. The VL sensor that has been built into the boost converter is used to detect the high voltage before it is boosted. The VB sensor that has been built into the battery ECU is used to detect voltage of the HV battery.
