After the battery needs to be replaced or the battery is aged, its charging capacity reserve capacity is still more than 60%. It is a pity to recycle it. If it can be used in a concentrated way, it is a resource that cannot be underestimated. If the space is not beautiful, it will still be abandoned, which will cause pollution and harm. Many batteries are replaced every year. If they can be managed and used in a centralized way, it is a resource and can reduce environmental pollution. This paper discusses the control of an electrical storage management system for reusable lithium-ion batteries. A lithium-ion battery (RLIB) is connected in parallel with a super capacitor (UC) and is connected to the DC link via a DC / DC boost converter. This structure is used to enhance the peak power of the system and reduce the discharge depth of the lithium-ion battery. The converter used here boosts the voltage of the supercapacitor to the same voltage level on the lithium-ion battery side, so that it can be used to adjust their current to meet demand, especially peak power. Here, the state space averaging method is used in EMS to manage the power flow between RLIB and UC. In order to manage the required load current alternately, switches S1 and S2 are configured between UC, RLIB and dc-link. EMS is used to perform current control between the two switches. Simulations were performed to confirm the effectiveness of the proposed EMS control scheme. This time, the automotive lithium-ion battery (RLIB) is adopted as the energy management system (EMS) of the lithium-ion battery (RLIB). This time proved the effectiveness of the new energy management system (EMS) and promoted the application of lithium ion batteries (RLIB).
