Description
本發明係有關一種電纜線及使用該電纜線之電池模組均充平衡系統，尤指一種能使電池模組內各電池芯之電量能平均充飽，以提高電池模組之使用效率及延長使用壽命者。 The invention relates to a cable line and a battery module balancing and charging system using the same, in particular, a battery capable of fully charging the battery cells in the battery module, thereby improving the use efficiency and extending the battery module. The service life.
電池管理系統(Battery Management System,BMS)係為電動車輛必不可少之核心系統，主要負責對電池模組進行安全監控及管理，以提高電池模組之使用效率及可靠性，並延長電池模組之使用壽命。電池管理系統主要包括一電池模組管理單元(Battery Management Unit,BMU)及一電池模組控制單元(Battery Control Unit,BCU)。電池模組管理單元(BMU)之間可透過各種通訊協定以傳送相關資訊，將資訊傳送給電池模組控制單元(BCU)，使對電池模組進行管理、警示與安全保護控制。 The Battery Management System (BMS) is an essential core system for electric vehicles. It is responsible for the safety monitoring and management of battery modules to improve the efficiency and reliability of battery modules and extend battery modules. The service life. The battery management system mainly includes a battery management unit (BMU) and a battery control unit (BCU). The battery module management unit (BMU) can transmit relevant information through various communication protocols and transmit information to the battery module control unit (BCU) to manage, alert and secure the battery module.
當電動車輛起動而使串聯之電池模組反覆充放電之後，將會導致電池芯之間有電壓差異、容量不均之現象，這個現象會讓電池模組之使用效率變差，也會造成電池模組之壽命衰減。而電池模組管理單元(BMU)除了可以監控電池芯之狀態外，還可以進行主動式或被動式電池平衡，補償輕微之電池芯不匹配，以延長電池模組之使用壽命。 When the electric vehicle is started and the battery modules connected in series are repeatedly charged and discharged, the voltage difference and the capacity unevenness between the battery cores may occur, which may make the use efficiency of the battery module worse, and may also cause the battery. The life of the module is attenuated. In addition to monitoring the state of the battery cells, the Battery Management Unit (BMU) can also perform active or passive battery balancing to compensate for slight cell mismatches to extend the life of the battery module.
電池模組管理單元(BMU)之平衡控制電路主要分為被動式平衡及主動式平衡二種。其中，被動式平衡係將較高電壓之電池芯的能量 直接在負載電阻上做功，將多餘之能量轉換成熱量消耗掉，此種方法只適用於在充電模式下抑制最強電池芯之電壓攀升，為限制功率損耗。其對於多個電池模組之組合而言，當其中一個電池芯充飽電之後，系統即會顯示已充電完成，但實際上仍可能會有多個電池芯尚在電量不足之狀態，因此，若要使各個電池芯之電量平均充飽，即會消耗很多能量。 The balance control circuit of the battery module management unit (BMU) is mainly divided into passive balance and active balance. Among them, passive balance is the energy of the battery with higher voltage Work directly on the load resistor to convert excess energy into heat. This method is only suitable for suppressing the voltage rise of the strongest battery core in the charging mode to limit power loss. For a combination of a plurality of battery modules, when one of the battery cells is fully charged, the system will display that the charging is completed, but in reality, there may still be multiple battery cells in a state of insufficient power, therefore, To make the battery cells charge on average, it consumes a lot of energy.
而主動式平衡係將多個較高電壓之電池芯之多餘能量一個一個進行能量之搬移，給其他電壓較低之電池芯使用。但在以多個開關迴路進行調節各個電池芯之充電量時，過多之開關會降低可靠度。而若開關一但產生短路現象，則會造成電池芯過充受損，甚至於起火燃燒。因此，上述兩種電池平衡之管理模式，其在平衡效率、製造成本及可靠度上尚有待改進之空間。 The active balance system transfers the excess energy of a plurality of higher voltage battery cells one by one to other battery cores with lower voltages. However, when adjusting the charge amount of each battery cell with multiple switching circuits, too many switches will reduce the reliability. If the switch produces a short circuit, it will cause the battery core to be overcharged and even burned. Therefore, the above two battery balancing management modes have room for improvement in terms of balance efficiency, manufacturing cost, and reliability.
有鑑於此，為了提供一種有別於習用技術之結構，並改善上述之缺點，發明人積多年的經驗及不斷的研發改進，遂有本發明之產生。 In view of the above, in order to provide a structure different from the conventional technology and to improve the above disadvantages, the inventors have accumulated many years of experience and continuous development and improvement, and the present invention has been produced.
