Research on Short-circuit Test Based on Intelligent Modular-48V Communication DC Power Supply
With the maturity of the lithium battery industry,the advantages of high energy density,small size,long life and continuous optimization of its economy make lithium batteries more and more widely used in communication power supply systems.However,for lithium batteries and especially smart lithium batteries with bidirectional DC/DC,due to comprehensive considerations of safety and economy,there is obviously a big gap in short-circuit discharge capacity in actual operation compared with traditional lead-acid batteries.There are great hidden dangers in the design of the power system and the safety design of the selective protection of power distribution,which may even cause major fire accidents.This article takes the intelligent modular power system as the research object,introduces the main components of the system,and conducts short-circuit test research on supporting batteries.In this article,we summarize the current problems existing in short-circuit faults in intelligent modular systems,and look forward to the research on short-circuit fault protection technology in intelligent modular systems.
