[Abstract]:In this paper, a design scheme of energy nondissipative management system for lithium battery pack is described by comparing several energy nondissipative topology schemes of battery pack and combining its advantages. Not only the battery pack can be monitored and protected, but also the battery energy efficiency can be improved. The main feature of the system design is that in the process of managing the battery pack, the energy that needs to be dissipated is concentrated in the super capacitor group, and the stored energy is fed back to the battery pack to prolong the battery life capacity under appropriate conditions. The non-dissipative energy management system described in this paper mainly uses STM32F107VCT6, a high performance chip of Italian semiconductor, as the main control chip. The temperature information is transmitted to the upper computer through can communication and TCP / IP communication. At the same time, the data are analyzed and processed, the equalization strategy is formulated, the charge state of the battery pack is calculated, and the lithium battery is reasonably protected. The data information of battery pack and capacitor group is mainly obtained by the monitor and management unit designed by hardware circuit, and the communication of data and the calculation of SOC based on equalization strategy are realized by C language program with flexible lower computer software. The data display is programmed by the upper computer software C # based on the WinForm platform of Visual Studio 2010. The upper computer interface can observe the working condition of each cell more succinctly and intuitively, and observe the changes of voltage, current and temperature. Analyzing the abnormal state in time and taking measures to effectively prevent the damage of the battery pack and strictly monitor the lithium battery pack, on the one hand, prevent the damage of the lithium cell monomer and prolong the service life of the whole battery pack, On the other hand, it protects the safety of the whole car. The energy nondissipative management system of lithium battery pack described in this paper is more suitable for pure electric vehicle because of its high specific power and can meet the needs of instantaneous start-up and fast charging of pure electric vehicle. Therefore, the system design of this paper can not only protect the lithium battery pack management, but also can be extended to compound power management, the latter is not discussed in this paper.
