Design and Research of Power Battery Temperature Control by PLC

Abstract

With the increasingly serious environmental pollution, electric vehicles are more and more favored by people, its power battery temperature control is an important premise to ensure driving safety. At the same time, with the gradual advancement of automobile intelligence and fully automatic driving program, the use of more powerful, more compatible controller has become an important research direction. In this paper, S7 200 Smart PLC, which is currently mature in the field of rail transit and industrial control, is used as the control core to build the hardware platform. Step 7-Microwin Smart collaborates with Kingview software to develop the control algorithm and interface, so as to realize the purpose of power battery temperature control and human-computer interaction. It has high research significance.
