Carrier phase-shift charging and discharging control strategy of hybrid energy storage system
In order to improve the safety and flexibility of hybrid energy storage operation,and ensure the balance and consistency of energy storage modules,firstly,according to the complex operation characteristics of electromagnetic launch load,a hybrid energy storage group cascade topology was de-signed,and its working principle and four operation modes were introduced in detail.Secondly,the research on carrier phase-shift charge and discharge control for hybrid energy storage packet cascade topology was carried out,and the application method and charging and discharging strategy of carrier phase-shift control were studied in combination with lithium battery charging mode,super capacitor charging mode and electromagnetic launch driving mode respectively.Finally,Experiments were con-ducted on the three operating modes mentioned above respectively to verify the feasibility of the car-rier phase-shift control strategy and the function of instantaneous bypass in the case of lithium battery module failure.At the same time,it has the advantages of improving system flexibility and maintai-ning the balance and consistency of each lithium battery energy storage module.
