Abstract
- Aimed at the miniaturization of the power-supply system for electromagnetic launch (EML) system, this paper deals with the problem of high rate pulse discharge of lithium batteries in the EML system. In order to reduce the number of batteries on series-parallel to increase the energy density, the factors such as safety, exotherm and life cycle must be taken into consideration, and there is need for optimization in terms of selection and design as well as discharge control of the battery. According to the power requirements of the EML system, the battery safety and discharge ability are important indexes in the aspect of selection and design, which refer to the design principle for selected batteries and the design scheme for raising their discharge ability under the precondition of discharge, and in the aspect of discharge control, the balancing-discharge control strategy is adopted to reduce the duration of high-rate discharge and the heat generation and extend the service life of batteries according to the EML operating conditions. Finally a test platform is established for verification. [ABSTRACT FROM AUTHOR]
