  • Worldwide India ranks second in production of fruit. Traditional harvesting of mango fruits is either carried out by hand plucking or using traditional harvester (Vedo). In both traditional harvesting and hand plucking methods, there are chances of liquid getting splashed over the body of operator and fruit may also get damaged which results in reduction in yield or return and traditional method is also time consuming. In addition, manual harvester requires more effort in operation.

  • Lead-acid starter batteries are used in land, sea, and air vehicles. Batteries for vehicles are discussed in this chapter. The production of starter batteries approaches 60 million pieces. About 16 million pieces are used for motor vehicle production and about 38 million pieces keep the vehicles ready for operation as back-up batteries. A considerable number of imported and exported pieces play a part in this market. With these numbers Europe achieves about two-thirds of the U.S. production. ...

  • Battery chargers are employed for charging starter, traction, and stationary batteries as well as for supplying stand-by power. The demands for these devices are dependent on the operation conditions. Charging starter and traction batteries is mainly conducted during recesses. Hereby the consumers are disconnected for charging batteries (Figure 13.1). Charging for stationary batteries allows an ensured stand-by power supply for parallel and switch operation for DC consumers.

  • An immense variety of electric appliances is offered today. A significant number of these can optionally or exclusively be operated with batteries. The applications cover all fields, ranging from industrial to domestic and hobby applications. The advantages of battery-powered appliances are obvious: The user can operate a device independently of mains supply anywhere desired. A power cord is not necessary as the power source, the battery, is incorporated in the device. While well-constructed devices are produced and sold in great numbers, others prove to be unsaleable and thus dead stock.

  • The properties of different forms of carbon and their potential, as active mass additives, for influencing the performance of valve-regulated lead–acid batteries are reviewed. Carbon additives to the positive active-mass appear to benefit capacity, but are progressively lost due to oxidation. Some forms of carbon in the negative active-material are able to resist the tendency to sulfation during high-rate partial-state-of-charge operation to some considerable extent, but the mechanism.

  • A major disadvantage of the lead/acid battery is the decrease in voltage during operation which makes it unsuitable for systems sensitive to voltage fluctuations. Additives like BaSO4 or SrSO4, which are isomorphous to PbSO4, have been used to overcome this problem. Phosphoric acid and the various phosphates have long been used to improve the performance of the positive electrode of the battery. A beneficial effect of phosphoric acid is to inhibit the rate of the self-discharge reaction of the positive electrode in the lead/acid battery. ...

  • India is the leading guava producer in the world today. The traditional harvesting method (manual picking) of guava fruit is a labour intensive, tedious, time consuming as well as risk involved process. Due to declining labour availability, risky operation, time consuming and increasing labour cost combined with more awareness to health and safety issues, it is mandatory mechanize the fruit harvesting operation. Therefore, was necessary to develop device that should be simple, power operated, easy assemble and disassemble, low cost and light in weight with a proper balance.

  • The cost of fuel and the effect of emission of gases from the burnt fuel into the atmosphere, this necessitated the use of the abundant solar energy from the sun as a source of power to drive a sprayer The Photovoltaic (PV) panel of 6 V, 5 W capacity configured to trap and convert the sun’s energy into the useful power was used to perform the work of spraying. Solar PV Panel was used for operating the sprayer and for charging a battery. The motor was used to regulate spraying liquid from the sprayer tank (5 lit.) and spray it through spinning disc nozzle.

  • Harvesting of crop is one of the important agricultural operations. The availability and cost of labour during harvesting season is the serious problem. Timely harvesting of the crop is vital to achieve better quality and higher yield of the crop. To ensure efficient and timely harvesting operation manually drawn battery powered reaper was developed at CAET, JAU, Junagadh. Performance evaluation of developed machine was carried out at different forward speeds (0.8-1.2 km/h,1.3-1.7 km/h and 1.8-2.2 km/h) and different cutter bar speeds (200 rpm, 300 rpm and 400 rpm).

  • Batteries are an essential component of virtually all aircraft electrical systems. Aircraft batteries are used to start engines and auxiliary power units (APUs), provide emergency backup power for essential avionics equipment and lighting systems, assure no-break power for navigation units and fly-by-wire computers, and to provide ground power capability for maintenance and preflight checkouts. Many of these functions are critical to the safe operation of the aircraft, so the reliability of an aircraft battery is of utmost importance.

  • 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....
