The efficient utilization, storage and management of energy are extremely important with regard to portable energy supply. The most abundant commodity available in the market for portable energy storage is the battery. Series strings of storage batteries are used in portable electrical appliances, electric vehicles, space vehicles, telephone industry, power system industries and military applications. Each battery when operating in series has a slightly different capacity due to manufacturing tolerances and environmental conditions. After several charge/discharge cycles, the battery strings tend to go out of balance. This is the motivation to develop a Battery Management system (BMS) to increase the capacity and efficiency of batteries.In this work, a BMS is developed for lead-acid batteries in series which monitors the state of all the batteries in the stack by keeping track of battery operational parameters such as voltage, charge during charging/discharging, idle periods and ensures proper operational conditions to safeguard the battery pack from degrading its useful life.</p><p>A novel active charge equalization technique is proposed to achieve the balancing of batteries in a stack in terms of both voltage and charge as the battery is being charged/discharged, and in idle periods in order to maximize the energy of stack. In the proposed scheme, the energy is transferred to the battery with lowest voltage from a battery with highest voltage. An overvoltage and over-discharge protection circuit has also been developed to reduce the degradation of battery life. The proposed scheme comprises of the following:• Dissipative schemes of charge equalization where extra energy is somehow dissipated across passive elements.• Bidirectional DC/DC converters which are expensive and tough to implement.• Switching capacitive schemes of equalization where energy is transferred to the neighboring cells.</p> 2011-06-23 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1306852610 http://rave.ohiolink.edu/etdc/view?acc_num=akron1306852610 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
