Description
The speed of the battery cooling blower assembly is controlled by the hybrid vehicle control ECU. Battery cooling blower assembly power is supplied when the FCTL terminal of the hybrid vehicle control ECU turns ON the battery blower relay. The hybrid vehicle control ECU sends command signals (SI) to the battery cooling blower assembly to get the fan speed corresponding to the HV battery temperature.

Information about the voltage applied to the battery cooling blower assembly (VM) is sent to the hybrid vehicle control ECU as a monitor signal using serial communication via the battery smart unit.
