A control method to improve the efficiency of a soft–switching non–isolated bidirectional DC–DC converter for hybrid and plug–in electric vehicle applications
Hybrid energy storage system (HESS) can be adopted in hybrid, plug–in hybrid, and pure electric vehicles (HEV, PHEV, and EV), where a bidirectional DC–DC converter (BDC) is used to connect batteries and ultra–capacitors. The efficiency improvement of the BDC is beneficial to increase the efficiency viability of HESS. Due to ZVS, high efficiency can be obtained at heavy load operations while the ...

Control and small-signal analysis of battery and supercapacitor hybrid energy storage systems
This paper is devoted to control strategies for an active battery and supercapacitor hybrid energy storage system using the master-slave control scheme, where the charging and discharging currents of the supercapacitor are dependent on that of battery and the current sharing ratio depends upon the load conditions. A small-signal model is proposed, which considers the variations in the currents of ...

A frequency control method for isolated photovoltaic-diesel hybrid power system without smoothing renewable power variations
In this paper, a frequency control method is introduced for photovoltaic-diesel hybrid system by using a load estimator and an energy storage system. The proposed method is compared with an energy storage based conventional control method and with a fuzzy based frequency control method. Simulation results show that the proposed method is feasible to reduce the frequency deviations of the isolated ...

A new life estimation method for lithium–ion batteries in plug–in hybrid electric vehicles applications
This paper presents a new approach to life estimation for lithium–ion batteries used in plug–in hybrid electric vehicles (PHEVs) applications. A new framework for battery life estimation is developed which investigates the effects of two primary factors of battery life reduction in PHEVs applications, namely, depth of discharge (DOD) and temperature (Tbatt), under typical driving conditions, ...

What is hybrid inverter?
An inverter is a critical element of any solar system, and you need it to convert the direct current (DC) electricity generated by your solar panels into distributed current (AC) electricity for your equipment. However, you’ll need a separate battery-specific inverter to convert power back and forth from AC to DC for battery storage and discharge if you install a solar panel system with a ...
