  • Electrical energy plays an important role in our daily life. It can universally be applied and easily be converted into light, heat or mechanical energy. A general problem, however, is that electrical energy can hardly be stored. Capacitors allow its direct storage, but the quantities are small, compared to the demand of most applications. In general, the storage of electrical energy requires its conversion into another form of energy.

  • Today the most important electrochemical storage systems for stationary applications are the lead-acid and the nickel/cadmium systems. Both of them have advantages and disadvantages which carefully have to be considered for best selection. Batteries for telecom applications are specially designed for long service life and hours of discharging time. Batteries for UPS applications are designed for discharges with high current over short times (minutes). Special battery constructions are offered for the different requirements. ...

  • To transport people and material growing transportation systems are needed. More and more of the energy for these systems is drawn from secondary batteries. The reason for this trend is economic, but there is also an environmental need for a future chance for electric traction. The actual development of electrochemical storage systems with components like sodium–sulfur, sodium–nickel chloride, nickel–metal hydride, zinc–bromine, zinc–air, and others, mainly intended for electric road vehicles, make the classical lead-acid traction batteries look old-fashioned and outdated....

  • Electric two-wheelers (E2Ws) are a category of vehicles in China that includes two-wheel bikes propelled by human pedaling supplemented by electrical power from a storage battery (bicycle-style E2Ws or pedelecs), and low-speed scooters propelled almost solely by electricity (scooter-style E2Ws). Besides pedelecs, most E2Ws rely exclusively on electric power, not on human pedaling. In many countries, E2Ws are allowed to operate in the bicycle lane and are considered a bicycle from a regulatory perspective (i.e., helmets and driver’s licenses are not required).

  • The oxide reduction diffusion (ORD) procedure has recently been applied in synthesizing hydrogen storage materials AB5 for Ni-MH batteries. Starting from metal hydroxides and La oxalat precursor, superfine powder alloys LaNi5, LaNi4.5Co0.5 and LaNi3.87Mn1.13 were obtained by this “soft-chemistry” route. Chemical composition, structure and morphology of alloy phases were examined by different analysis techniques such as AAS, EPMA, X-ray and TEM. The H2-absorption and desorption behavior of crystalline products was determined by Sieverts’ method.

  • Since the penetration level of Photovoltaic (PV) system continuously increases, the negative impact caused by the fluctuation of PV power output needs to to be carefully managed. This paper proposes a coordinated control algorithm based on a discrete wavelet transform to eliminate both short-term and long-term fluctuations by using hybrid energy storage system (HESS). While the short-term fluctuation is mitigated by using an electric double-layer capacitor (EDLC), the longterm one is reduced by the support of a Li-ion battery.

  • One of the most recent optimization techniques applied to the optimal design of photovoltaic system to supply an isolated load demand is the Artificial Bee Colony Algorithm (ABC). The proposed methodology is applied to optimize the cost of the PV system including photovoltaic, a battery bank, a battery charger controller, and inverter. Two objective functions are proposed: the first one is the PV module output power which is to be maximized and the second one is the life cycle cost (LCC) which is to be minimized.

  • SnS2 has been investigated as anode material for lithium ion batteries. To obtain anode material having high capacity and long-term lifespan, in the present work, a nanostructured composite comprising SnS2 nanosheets and CMK-3 ordered mesoporous carbon has been designed. The CMK-3/SnS2 composite is fabricated via incipient wetness impregnation, followed by chemical reduction and chemical conversion in an inert gas at high temperature. The obtained composite exhibits boosted lithium storage behaviors involving high specific capacity, fast rate response and stable cyclability.

  • Vehicles that utilize more than one energy source for propulsion are usually termed hybrid vehicles. Although the onboard energy storage system (ESS) may be a flywheel or a hydraulic accumulator, most hybrid vehicles use chemical batteries or capacitors and are termed hybrid-electric vehicles. Fuel cells (FCs) may be used in hybrid-electric vehicles as primary power sources instead of conventional internal combustion engines (ICEs). In this article, ICE–battery hybrid transit buses are discussed specifically and contrasted with conventional drive buses. ...

  • The NS2 is a two reader panel providing access control for up to two doors through the use of Wiegand readers. The NS2 may be used as a standalone panel with independent card and transaction storage or, with a software upgrade, as a fully monitored online access control device. Communication to the front-end computer is achieved through an RS-232 serial cable (included with installation kit) or an optional RS-485 interface. Each RS-485 interface is capable of communicating with up to 31 panels. The NS2 is designed for tile mount using the ENC10 enclosure.

  • The Zoning Resolution’s off-street parking regulations were written before car sharing existed. Therefore, the zoning text currently addresses only private automobiles and car rental establishments, the latter of which are commercial uses. In addition, the definitions of “public parking lot” and “public parking garage” generally prohibit the storage of commercial vehicles in such facilities. However, car sharing is a use that is more appropriately characterized as somewhere between private automobile and traditional car rental. ...
