Questions about Battery Cooling Device
How does the compressor rotation speed affect battery cooling efficiency?
The compressor rotation speed directly impacts the rate at which the refrigerant circulates, affecting the cooling capacity of the device. By increasing the rotation speed during rapid charging, the device can effectively manage the battery temperature and prevent overheating.
What are the potential noise implications of increasing the compressor rotation speed?
Increasing the compressor rotation speed can lead to higher noise levels during operation. However, by setting a predetermined rotation speed based on noise considerations, the device can balance cooling efficiency with noise management for a more comfortable user experience.
Original Abstract Submitted
The battery cooling device that cools a battery by circulating a refrigerant by a compressor and cools air blown into a vehicle compartment, and when the battery is being rapidly charged, the rotation speed of the compressor is increased. More specifically, the upper limit rotation speed of the compressor is increased to a predetermined rotation speed. At this time, the predetermined number of revolutions is determined based on a maximum allowable noise level at the time of rapid charge of the battery.
