Analysis of the Battery Management System for Electric Energy Vehicles
摘要
在目前的生活當中，台灣機車歷經半世紀之發展，然而在全球能源短缺、提倡綠色環保之際，台灣機車產業也順應潮流，朝輕量化、低汙染、省能源等方向發展，以符合各國環保要求，「電動機車」在機車產業將扮演越來越重要的角色，期發展也受到各國的重視，紛紛推出電動能源車種。其中電池對於電動車輛是最具策略性之元件，對電動車輛之性能、續航力、使用方便性等有絕對之影響性，電池性能將影響電動車輛之發展。將電池管理模組(BMS)為發展電動機車之關鍵技術，主要監控與管理整車電池模組並且提供預警保護之功能，進而可延長電池之使用壽命。再者，可加入通訊功能取得相關電池資料累積，進行電池壽命與健康狀態診斷與分析。更可透過電池管理模組(BMS)可將電池資訊傳送至能量管理系統(EMS)來進行整車能量管理，結合適當的控制策略，達到有效且高效能的使用電池的目的，優秀的電池管理系統將可以提高電池模組使用之安全性、延長電池模組使用之壽命、並可有效降低電池組使用成本等特點。本技術報告主要將電動機車的核心單元，電池管理模組搭配電池管理系統 (Battery Management System)、進行分析電芯與應用研究之實現，並透過CAN、MODBUS或RS-485等通訊協定來傳送相關資訊，此外更可進一步將資訊傳送到更上層之電池管理系統控制核心(MCU)，根據這些資訊來對電池作管理、警示與安全保護等控制策略。

Techniques of the Taiwan motorcycle industry have been developed for half a century. However, under the circumstance of the global energy shortage, to be economical and ecological of energy, the Taiwan motorcycle industry also conforms to the trend towards lightweight, low pollution, and energy. In other words, in line with national environmental protection requirements, the direction of developing "motor vehicle" in the motorcycle industry will play an increasingly important role. Consequently, the Taiwan motorcycle industry has launched different kinds of electric energy vehicles for gaining international attention. The performance of the vehicle's electric vehicles lies in its battery. The battery performance will affect the development of electric vehicles. Furthermore, the battery management system module (BMS) is key technology for the development of electric vehicles. The BMS cannot only monitor and manage the entire vehicle battery module but also provide early warning protection function for extending the battery life time. Moreover, the communication function can be added to obtain the relevant information of the battery itself for increasing the battery life and executing its state diagnosis and analysis. In addition, through the BMS the battery information can be passed to the energy management system (EMS) to carry out the entire vehicle energy management for the effective use of the battery. This technical report will focus on analyses of the BMS and the secondary battery by sending the battery information via CAN, MODBUS or RS-485 protocols to the battery control unit (MCU). Based on the receiving information, the battery can be managed for security alerts and other control strategies.
