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. . | 16 Feasibility Study for Appliances H. A. KIEHNE and W. RAUDSZUS 16.1 BATTERY-OPERATED APPLIANCES 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 reason for this is often the use of a battery that is unsuitable for one of the following reasons An inconvenient electrochemical system was chosen. The battery was not dimensioned correctly. Wrong presumptions regarding the battery s properties or the energy content were made. A battery-powered device is said to be well designed when it resembles a mains-operated one in function as closely as possible. While power consumption has only since the energy crisis become an important subject for mains-dependent appliances it must be minutely treated and minimized when battery powering is demanded. The goal is perfect function of the appliance with the lowest possible power consumption. Copyright 2003 by Expert Verlag. All Rights Reserved. The engineer or designer of any appliance should exhaust all possibilities of lowering power consumption by raising the efficiency of a device with sophisticated electronics and modern materials before deciding which battery to use. A substantial amount of energy can be saved by these means. Only when the design is ready and optimized a load profile and power demand of the appliance can be issued. Now the task is installation of a small and cost effective but big enough battery. To take care of this task a great amount of experience is necessary. Table .
