Optimal Design of Power Management System for Real Time Information Terminal of Construction Machinery Car

Abstract

In order to solve the problem of throwing load when starting the vehicle and the need of entering the low power consumption mode during the non-construction period, a theoretical analysis and experimental verification method is adopted to design a construction machinery information collecting terminal for power distribution and management among multiple modules Power Management System. Test results show that: The optimized solution meets the power supply requirements of each module of the terminal, can adapt to the complicated application environment in the vehicle, can effectively protect the lithium battery, and achieve the purpose of optimizing the design.
