Description

All-weather intelligent military vehicle-mounted energy storage system
Technical Field
The invention relates to the technical field of vehicle-mounted energy storage, in particular to an all-weather intelligent military vehicle-mounted energy storage system.
Background
In the aspect of military equipment, China always researches the application of lithium batteries and battery energy storage systems, but the research field of military battery energy storage systems is different from that of foreign countries.
Part of the equipment still adopts traditional fossil fuels such as diesel oil and the like
At present, most of equipment adopts diesel oil and other oil materials for energy supply. The oil is flammable and explosive, has high requirements on storage conditions, and can cause explosion if the oil is not stored properly, so that energy and equipment loss is caused. In addition, the diesel engine has high noise when being started, and the concealment is reduced; the diesel oil is used, the energy supply is also considered, an oil depot system needs to be built, and the cost is increased; reduced maneuverability and flexibility of battle, and pollution to the environment caused by using fossil fuel. The novel batteries such as lithium ion batteries have the characteristics of large capacity, high safety, light weight, no pollution and the like, and if the novel batteries are used for replacing fossil fuels such as diesel oil and the like, the defects can be reduced to a great extent, and the fighting efficiency of weaponry is improved.
(II) less renewable energy source utilization of digital equipment
Digital military equipment cannot be separated in the scientific and technological war, the field of digital equipment is developed towards light weight, portability and invisibility, and most of the digital equipment cancels renewable energy power supply and basically adopts secondary chemical batteries for power supply, so that the problem of charging is related. Especially, in some digital devices with high requirements on power quality, when power supply is not timely and unstable, the digital devices have the problems of unstable operation, performance reduction and the like, and serious strategic fault loss can be caused. This problem can be solved to some extent if a method combining silicon power generation with digital equipment is used. But the problems to be considered include: how to assess the minimum silicon power cell power required to meet the digital equipment? Is the harmonic wave generated during charging of silicon-on-insulator (SIL) have an effect on high-precision digital equipment, particularly communication equipment? In the face of unstable natural climate, in the continuous rainy day or the environment with insufficient silicon light-emitting line, if the power required by the equipment is continuously supplied? And so on, are difficult to solve.
(III) the popularization degree of the novel battery is small
Although in addition to the high-tech military field, many troops have now begun to use battery energy storage. Unlike the high-tech field, however, the battery requirements of the army are not as high as those of the aerospace field. At present, due to problems in cost or actual demand and the like, energy storage batteries used by many troops are still lead-acid batteries, chemical cost contained in the lead-acid batteries affects local environment and ecology and may cause harm to bodies and minds of officers in defense. The lithium ion battery is nontoxic, has the characteristics of high energy ratio, high power ratio and the like, and can provide lasting and stable power supply for various equipment in modern informatization and digitization wars.
Battery energy storage is currently the most widely used and considered as the most promising energy storage unit. Currently, great progress has been made in the research and application of battery energy storage technology, for example, from the past research and application of only a battery cell and a small-capacity battery energy storage system, to the research and application of technologies such as large capacity, large scale, battery grouping, and the like.
At present, the lithium battery is expected to become a secondary battery which has the best prospect and the fastest development in a long period of time after the nickel-cadmium, nickel-hydrogen and lead-acid batteries due to the characteristics of long cycle life, good safety performance and high-temperature performance, relatively low price, high energy ratio, high power ratio, no memory effect and the like.
At present, lithium batteries with wider application and other energy storage batteries meeting requirements become an indispensable part in a modern war mode, and the importance of energy sources in the aspect of the logistics work of modern military is not negligible, such as: how to provide daily required energy for remote sentries with difficult power supply, how to ensure reliable and continuous supply of weaponry and vehicle power, and the like, all of which need energy storage technology as support, and battery energy storage is a mature technical circuit at present, so that the development of the battery energy storage technology is always an important subject for military research in various countries.
