本發明係關於一種電動車電池並聯控制系統，特別是關於一種每一電池皆具有獨立電池管理系統之電動車電池並聯控制系統。 The invention relates to an electric vehicle battery parallel control system, in particular to an electric vehicle battery parallel control system with an independent battery management system for each battery.
近年來由於全球暖化日益嚴重，使得環保意識抬頭，配合油價高漲，各國政府及企業紛紛尋找新的替代能源或提高二次電池的轉換效率以期望減少石化燃料之使用，進而降低溫室氣體的排放，减緩全球暖化之速度。其中傳統車輛主要是使用石化燃料作為動力來源，不但耗用大量石油資源，也是溫室氣體排放的主要禍首之一。在全球節能减碳的趨勢下，許多國家都將車輛電動化作為二氧化碳減量的重要措施之一，進而積極發展電動車產業。 In recent years, due to the increasing global warming, environmental awareness has risen. In line with the high oil prices, governments and companies are looking for new alternative energy sources or improving the conversion efficiency of secondary batteries in the hope of reducing the use of fossil fuels, thereby reducing greenhouse gas emissions. To slow down the pace of global warming. Among them, traditional vehicles mainly use fossil fuels as a power source, which not only consumes a lot of oil resources, but also is one of the main causes of greenhouse gas emissions. Under the trend of global energy conservation and carbon reduction, many countries have adopted vehicle electrification as one of the important measures to reduce carbon dioxide, and thus actively develop the electric vehicle industry.
然而，該電動車在實際使用上仍具有下述問題，例如：目前電動車之發展受到電池容量之限制而局限了其續航能力，因此需要並聯更多電池以增大容量，以延長行駛里程。但是當電池並聯時有可能會因為電池特性不匹配，電壓量測值僅為並聯電池中最高電壓之單體電池電壓，無法反應單體電池之真實特性。另外能量密度、充放電功率以及電池之包裹性及使用過程發生碰撞所發生高壓電伏，皆是威脅電動車安全性能之重要因素； 此外，隨著時間充放電次數的增加，所有電池非一致性將隨著時間逐漸明顯，由於電源管理系統對並聯電池組單體特性精確性低，進而造成某單一電池失效而造成整體電池之報廢，增加成本的支出。 However, the electric vehicle still has the following problems in practical use. For example, the current development of electric vehicles is limited by the battery capacity and limits its endurance. Therefore, more batteries need to be connected in parallel to increase the capacity to extend the mileage. However, when the batteries are connected in parallel, the battery characteristics may not match, and the voltage measurement value is only the voltage of the highest voltage of the parallel battery, and cannot reflect the true characteristics of the single battery. In addition, the energy density, charge and discharge power, and the encapsulation of the battery and the high voltage voltage generated by the collision during use are important factors that threaten the safety performance of the electric vehicle; In addition, as the number of times of charge and discharge increases, all battery inconsistencies will become apparent over time, due to the low accuracy of the power management system's single-cell characteristics, resulting in the failure of a single battery and the rejection of the entire battery. , increase the cost of spending.

請再參照第2a圖所示，本發明第一實施例之第一電池模組11啟動之電路示意圖，在本實施例中，該切換控制模組16包含一切換單元161，在本實施例中該切換單元161為一繼電器，該繼電器共有三個接點：A、B、C，其中C為一共接點(common)，A及C為常閉(normally close)接點，通過該啟動線19連接該第一電池111之輸出端；此時B及C為常開(normally open)接點，該第一電池111向該整車管理系統15供電，該第二電池121不供電。其中該切換單元161可為按壓開關、切換開關或液晶開關形式，但本發明並不侷限於此。 Referring to FIG. 2a, a circuit diagram of the first battery module 11 of the first embodiment of the present invention is activated. In this embodiment, the switching control module 16 includes a switching unit 161. In this embodiment, The switching unit 161 is a relay having three contacts: A, B, and C, wherein C is a common point, and A and C are normally close contacts, and the starting line 19 is passed through the starting line 19 The output end of the first battery 111 is connected; at this time, B and C are normally open contacts, and the first battery 111 supplies power to the vehicle management system 15, and the second battery 121 does not supply power. The switching unit 161 may be in the form of a push switch, a changeover switch or a liquid crystal switch, but the invention is not limited thereto.
在本實施例中，使用者可依照電量顯示，使用一鎖頭或主開關(未繪示)控制該切換單元161，以切換任一電池。此時，該切換單元161(繼電器)將切斷另一電池，換言之，一次只能有一次電池作用。該切換單元161亦可由該整車管理系統15通過該第一或第二電池管理系統112、122監測電量驅動一驅動電路(未繪示)，以自動決定停止供電或進行電池切換。 In this embodiment, the user can control the switching unit 161 to switch any battery according to the power display by using a lock or a main switch (not shown). At this time, the switching unit 161 (relay) will cut off another battery, in other words, the battery can only be used once. The switching unit 161 can also be driven by the vehicle management system 15 to monitor a power driving a driving circuit (not shown) through the first or second battery management systems 112, 122 to automatically decide to stop power supply or perform battery switching.
該切換控制模組16之動作可設定於電動車停止行駛的時候執行，可預設為當該整車管理系統15判定車輛速度為零或是零電壓輸入時，為對第一或第二電池111、121進行安全管理，通常包括在車輛故障或發生碰撞的狀態下切斷系統電源等作法，如增加一電池保護電 路，使其具備單體電池或電池模組的斷接功能，或是在熱管理上透過風扇等冷却系統，熱電阻等加溫系統使電池處於正常工作溫度範圍。特別在電池系統的高壓保護設計上，還須包括主動及被動式安全設計，如：電池組二次絕緣、絕緣電阻檢測、自動危險電壓斷開、手動電壓切斷等。 The action of the switching control module 16 can be set when the electric vehicle stops driving, and can be preset to be the first or second battery when the vehicle management system 15 determines that the vehicle speed is zero or zero voltage input. 111, 121 for security management, usually including the system power supply in the state of vehicle failure or collision, such as adding a battery protection The road has the function of disconnecting the single battery or the battery module, or through the cooling system such as a fan in the thermal management, and the heating system such as the thermal resistance keeps the battery in the normal operating temperature range.

在本實施例中，該切換單元161(繼電器)還可在電池之充電狀態異常時，由該整車管理系統15下達指令給該電池控制單元14，進而執行斷路及漏電安全防護動作。由於動力電池相關電路皆為高壓系統，最高電壓可達600伏，故為滿足安全防護可甚至安裝數個繼電器或保險裝置。 In this embodiment, the switching unit 161 (relay) can also issue an instruction to the battery control unit 14 by the vehicle management system 15 when the state of charge of the battery is abnormal, thereby performing an open circuit and a leakage safety protection action. Since the power battery related circuits are all high voltage systems, the maximum voltage can reach 600 volts, so even several relays or safety devices can be installed to meet the safety protection.
請再參照第2b圖所示，本發明第一實施例之第二電池模組12啟動之電路示意圖，當該第一電池111電量不足或出現其他異常情况時，可切換該切換單元161，令常開接點B、C導通，通過該啟動線19改由第二電池進行供電，其工作原理與第一電池模組11啟動相同，於此不再贅述。 Referring to FIG. 2b, the circuit diagram of the second battery module 12 of the first embodiment of the present invention is activated. When the first battery 111 is low in power or other abnormal conditions occur, the switching unit 161 can be switched. The normally open contacts B and C are turned on, and the second battery is powered by the starting line 19. The working principle is the same as that of the first battery module 11, and will not be described here.
在本實施例中，該整車管理系統15還可包含一顯示器，藉由該電池控制單元14接收來自該電池管理系統的訊息，當該第一或第二電池111、121電壓或電量不足時，該整車管理系統15可依照一預設值透過該顯示器輸出相應的燈光、影像或聲音訊號，以提醒使用者進行電池切換。 In this embodiment, the vehicle management system 15 can further include a display, by the battery control unit 14 receiving a message from the battery management system, when the first or second battery 111, 121 voltage or power is insufficient. The vehicle management system 15 can output a corresponding light, image or sound signal through the display according to a preset value to remind the user to perform battery switching.
請參照第3圖，本發明第二實施例之電動車電池並聯控制系統之結構示意圖，其中該電動車電池並聯控制系統可配置兩個、三個、四個或以上之電池111、121...，且每一電池111、121...均配有一獨立電池管理系統112、122...，當使用本發明第二實施例之電動車電池並聯控制系統時，同一時間內只有一個單位的電池用於供電，進而實現多組電池之交替供電，以延長行駛里程。 Referring to FIG. 3, a schematic structural diagram of a parallel control system for an electric vehicle battery according to a second embodiment of the present invention, wherein the electric vehicle battery parallel control system can be configured with two, three, four or more batteries 111, 121.. And each of the batteries 111, 121... is equipped with an independent battery management system 112, 122, ..., when using the electric vehicle battery parallel control system of the second embodiment of the present invention, there is only one unit at a time. The battery is used for power supply, which enables alternating power supply of multiple sets of batteries to extend the mileage.
藉此，不但可精確監測每一電池的操作狀態，有效淘汰特定電池，並可將不正常運作的電池與其他電池隔離，避免整組電池起火或爆炸，因而進一步相對增加電動車的安全性。 Thereby, not only can the operation state of each battery be accurately monitored, the specific battery can be effectively eliminated, and the abnormally operating battery can be isolated from other batteries, thereby avoiding the fire or explosion of the entire battery, thereby further increasing the safety of the electric vehicle.
如上所述，相較於習用電動車電池並聯控制系統雖能進行並聯電池監控，卻因各電池非一致性將隨著時間逐漸明顯，而導致無法精確各電池狀態之缺點，本發明藉由獨立之電池管理系統，其確實可以有效對各電池進行獨立監控，還可分散安裝，避免額外增加的模組製作，以減少材料成本並提升空間之利用率。 As described above, compared with the conventional electric vehicle battery parallel control system, although the parallel battery monitoring can be performed, the inconsistency of each battery will become obvious over time, resulting in the inability to accurately predict the state of each battery, and the present invention is independent. The battery management system can effectively monitor each battery independently, and can also be installed in a distributed manner to avoid additional module production, thereby reducing material costs and improving space utilization.
雖然本發明已以較佳實施例揭露，然其並非用以限制本發明，任何熟習此項技藝之人士，在不脫離本發明之精神和範圍內，當可作各種更動與修飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 The present invention has been disclosed in its preferred embodiments, and is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
