Dc/Dc Converter Cooling Control

If deterioration of the DC/DC converter cooling performance causes the temperature to rise, the Li-ion battery controller transmits the DC/DC converter cooling mode request signal to HPCM. When HPCM receives the signal, it transmits the DC/DC converter cooling mode signal to A/C auto amp. via CAN communication. When the A/C auto amp. receives the signal, it introduces outside air to lower the temperature of the DC/DC converter.
