运载火箭箭上锂离子电池型谱化研究与实践OACSTPCD

As a primary energy source for the electrical equipment on launch vehicle,the battery is the key sin-gle machine of the electrical system on the vehicle.In order to standardize the development and use of launch vehicle mounted lithium batteries,a research approached for rocket mounted lithium battery spectrum design is proposed,which includes gradient design of spectrum characteristic parameters,unified type design of compo-nents,unified design of test conditions,and unified design of usage and maintenance requirement.A launch ve-hicle mounted lithium battery spectrum is established and 15 kinds of vehicle mounted lithium batteries series shelf products are formed,which are successfully practiced on the CZ-3A launch vehicle.The development of vehicle mounted lithium battery spectrum compresses the models of 28 V lithium batteries for launch vehicle from 31 to 11,reduces the varieties of batteries by 64.5％.It unifies the technical status of products,reduces the cost and difficulty of battery development,production and quality control,effectively supports the batch pro-duction of vehicle mounted lithium batteries and high density emission of launch vehicles.
