Speed control system for cooling media circulation pump of battery pack and control method for cooling media circulation pump thereby

摘要

The present invention is to solve the above problems, in measuring the number of revolutions of the circulating pump, there is no need for a separate sensor, using a device such as a microcomputer already installed in the battery pack, the power stage of the circulating pump It is possible to provide a cooling water circulation pump speed control system of a battery pack that can be directly controlled and a cooling water circulation pump control method using the same. Since the present invention does not have a separate sensor, a separate power source for these devices, a power line, and a separate module for analyzing the values measured by the device are not required, so the configuration is simple and the volume is small. In addition, there is an advantage that the voltage can be directly adjusted using a microcomputer device for measuring current.
