【摘要】：本文通過對電池組的幾種能量非耗散型均衡拓撲方案對比,結合其優(yōu)勢,描述了一種用于鋰電池組的能量非耗散型管理系統(tǒng)的設計方案。不僅可以對電池組進行監(jiān)控保護,還可以提高電池組的能量利用率。本文系統(tǒng)設計的最大特點就是在管理電池組的過程中,將需要耗散掉的能量,集中在超級電容組中,將儲存的能量在適當情況下反哺給電池組以延長續(xù)航能力。本文描述的鋰電池組的能量非耗散型管理系統(tǒng)主要以意法半導體的高性能芯片STM32F107VCT6作為主控芯片,將電池組和電容組的電壓,電流,溫度等信息通過CAN通訊和TCP/IP通訊傳送至上位機顯示,同時分析處理數(shù)據(jù)、制定均衡策略、計算電池組荷電狀態(tài),合理保護鋰電池組。電池組和電容組的數(shù)據(jù)信息主要依靠硬件電路設計的監(jiān)控管理單元得到;數(shù)據(jù)的通訊、均衡策略、SOC計算由下位機軟件靈活的C語言程序編寫實現(xiàn);數(shù)據(jù)顯示由上位機軟件C#基于Visual Studio 2010的WinForm平臺編寫實現(xiàn),該上位機界面可以更加簡潔直觀的觀察每個電池單體的工作狀況,通過觀察電壓,電流和溫度的變化,及時分析出異常狀態(tài)并采取措施,有效阻止電池組的損害,對鋰電池組的嚴格監(jiān)控,一方面防止了鋰電池單體的損害,延長了整個電池組的使用壽命,另一方面保護了整車的安全。本文描述的鋰電池組的能量非耗散型管理系統(tǒng)因為超級電容組存在比功率大的特點,更適用于純電動汽車,可滿足純電動汽車的瞬時啟動和快充的需求。所以本文的系統(tǒng)設計不僅可以對鋰電池組進行保護管理,而且可以拓展為復合電源管理,后者不作為本文討論內容。
[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.
