This paper describes an analytical feasibility study of the use of chemical storage batteries as the power supply for an electric railgun. The railguns studied are capable of accelerating 1 to 10 kg projectiles to 10 km/sec. Batteries were studied because they offer extremely high energy storage density although they operate at low voltage. Thus, an inductive store must be used to provide pulse...
In this paper, battery/ultracapacitor hybrid energy storage system (HESS) is proposed for electric vehicles, it is used to large dc-dc converter by using ultra capacitor and battery. It is also use the dc link for the purpose of maintain the peak voltage value. By the help of battery and ultracapacitor they are operate. The battery is used to charging the capacitor in case of discharge the capa...

An RF energy harvesting and storage system is described that trickle charges a battery from incident power levels as low as -25 dBm referred to the feedpoint of an 8 dBi patch antenna. The circuit is optimized for the indoor ambient power range typically observed in the 2.4 GHz ISM band so that we can harvest the energy provided by nearby Wi-Fi, Bluetooth and other devices. In this incident pow...
Battery is the most widely used energy storage device. Since its invention, it has become a common power source for various household, commercial and industrial applications. Despite its ever increasing importance, many challenges remain unsolved to characterize and manage the battery. Among them, one fundamental issue is the estimation of state of charge (SoC), and Sate of health (SOH) of batt...
This work presents a battery-ultracapacitor hybrid energy storage system (HESS) for pulsed loads (PL) in which ultracapacitors (UCs) run the pulse portion of load while battery powers constant part load. Energy stored UC depends upon square its voltage that’s why an active parallel topology with two bidirectional converters (BDC) is employed here that assigns separate BDC to control betw...
