Description
本案關於一種電池均溫控制系統,尤指一種可對電池模組各別進行熱管理之電池均溫控制系統。This case relates to a battery uniform temperature control system, especially a battery temperature uniform control system that can perform thermal management on battery modules.
隨著鋰電池的廣泛應用及對其電壓需求的不斷提升,一般常用的電池機櫃內所置放的鋰電池數量極易超過200顆以上。如此龐大的鋰電池數量,導致其電池熱管理較難管控。一般而言,於電池機櫃中會設置複數個電池模組,且每一電池模組中係串聯設置複數個電池串聯,並透過空調裝置對該等電池模組進行熱管理。With the widespread application of lithium batteries and the continuous improvement of their voltage requirements, the number of lithium batteries placed in commonly used battery cabinets can easily exceed 200 or more. Such a large number of lithium batteries makes it difficult to control the thermal management of the batteries. Generally speaking, a plurality of battery modules are arranged in the battery cabinet, and a plurality of batteries are arranged in series in each battery module, and thermal management of the battery modules is performed through an air conditioner.
電池模組的熱管理主要在於如何加強電池的均溫性。於習知技術中,造成電池不均溫的原因包含電池來自不同生產批料、電池本身阻抗不同、模組擺放位置 (高處與低處擺放)、內部風場不均等和外部環境高溫或低溫和陽光照射面的不同。此外,由於電池的發熱量亦為動態性質,其會依照不同的電流或時間產出不同的熱量。此種種的因素讓電池模組的熱管理變得困難重重、且難以處理,更遑論當許多的電池模組同時設置於電池機櫃中時,更是難以對各別電池模組一一進行熱管理。The thermal management of the battery module mainly lies in how to enhance the temperature uniformity of the battery. In the conventional technology, the reasons for the uneven temperature of the battery include that the battery comes from different production batches, the impedance of the battery itself is different, the placement of the module (high and low), uneven internal wind field, and high temperature in the external environment Or the difference in low temperature and sun exposure. In addition, because the heat generated by the battery is also dynamic, it will produce different heat according to different currents or time. All these factors make the thermal management of battery modules difficult and difficult to handle, not to mention that when many battery modules are installed in the battery cabinet at the same time, it is even more difficult to perform thermal management on each battery module .
在習知技術中,戶外型的電池儲能機櫃常會採用空調裝置進行制冷,使電池機櫃內之環境溫度維持在20~30度,以避免電池過熱。然而,環境溫度並不等於電池溫度,且電池被包裹在複雜的電池模組結構中,若此時櫃內溫度出現局部高溫或局部低溫,則該局部高溫或局部低溫處的電池模組內的電池溫度則可能會過高或過低。倘若單顆電池的溫度過高或過低,超出其預定的保護值,則該電池模組將因保護該單顆電池的因素而暫停運轉,如此將使得模組中其它溫度正常的電池也無法運作,進而損失總電容量。In the prior art, outdoor battery energy storage cabinets are often cooled by an air conditioner to maintain the ambient temperature inside the battery cabinet at 20-30 degrees to avoid overheating of the batteries. However, the ambient temperature is not equal to the battery temperature, and the battery is wrapped in a complex battery module structure. If there is a local high or low temperature in the cabinet at this time, the battery module at the local high or low temperature will The battery temperature may be too high or too low. If the temperature of a single battery is too high or too low and exceeds its predetermined protection value, the battery module will suspend operation due to the factors that protect the single battery, so that other batteries with normal temperature in the module will not be able to operation, thereby losing the total capacity.
除此之外,前述電池的不均溫性也會間接影響到電池的壽命。由此可見,如何做到櫃內電池溫度平均和熱處理,已經成為業界的重要課題。是以,如何發展一種可改善上述現有技術所遇到問題的電池均溫控制系統,實為重要的課題之一。In addition, the uneven temperature of the aforementioned battery will also directly affect the life of the battery. It can be seen that how to achieve the average temperature and heat treatment of the battery in the cabinet has become an important issue in the industry.

請同時參閱第1圖、第3圖及第4圖。如前所述,每一電池模組5之溫度感測模組54透過其複數個溫度感測器均持續地對每一個電池51進行溫度監測,並將該等溫度監測之資料傳遞至電池模組5之控制單元52,以取得該電池模組5之工作溫度資訊(即第一平均溫度),其後再經由連接組件56將此工作溫度資訊傳送至中央控制模組4,並與一基準溫度做比較,以取得每一電池模組5之工作溫度與該基準溫度之偏差值。於本實施例中,該基準溫度係為複數個電池模組5A、5B、5C、5D…之第二平均溫度,意即每個電池模組5A、5B、5C、5D…將溫度感測模組54所監測到的工作溫度(第一平均溫度)各別傳送至中央控制模組4後,則由核心處理器41進行運算,計算出複數個電池模組5A、5B、5C、5D…當下之平均溫度,即為第二平均溫度,以作為溫度調控之基準溫度。Please also refer to Figure 1, Figure 3 and Figure 4. As mentioned above, the
於本實施例中,複數個電池模組5A、5B、5C、5D…之熱管理為動態之熱管理,其主要依據空調裝置3當下之工作模式(冷卻模式或加熱模式)及上述之偏差值是否超出一預定值,以各別地進行電池模組5A、5B、5C、5D…之熱管理。舉例來說,若此時空調裝置3係處於冷卻模式,即其輸出冷空氣,且電池模組5A之偏差值為一正數,並高於一預定值時,則中央控制模組4之核心處理器41將傳送一高速運轉指令至電池模組5A。於本實施例中,該偏差值所能容受的預定值為5℃,但不以此為限。換言之,若電池模組5A之工作溫度高於基準溫度5℃,電池模組5A之控制單元52即會依據此高速運轉指令,使風扇組53啟動相對應之高速運轉模式,以對電池模組5A內之複數個電池51進行降溫,俾調降電池模組5A之工作溫度,以使該偏差值調整至預定值內。In this embodiment, the thermal management of the plurality of
請同時參閱第5圖、第6A圖、第6B圖及第7圖。承前所述,當電池模組5A之風扇組53執行高速運轉模式時,其將對電池模組5A內之複數個電池51進行強制散熱,即為使該複數個電池51所產生的熱經由風扇53a、53b之高速運轉,而由第二側面503上之複數個第二開口503a及第三開口503b快速向外輸送。於此同時,空調裝置3所提供之冷源,即冷空氣將由第一側面502上之第一開口502a被快速地導入電池模組5A內,並依序流經該複數個電池51,以進行散熱,並降低電池模組5A之工作溫度。以及,溫度感測模組54持續地監測電池模組5A之工作溫度,並將該工作溫度資訊經由控制單元52傳送至中央控制模組4,以再次進行運算,若經由前述溫度調控程序後,電池模組5A之工作溫度與基準溫度(即第二平均溫度)之偏差值降至預定值(即5℃)內,則中央控制模組4將再傳送中速運轉指令至電池模組5A。電池模組5A之控制單元52接獲中速運轉指令後,將傳送至風扇組53,使其啟動相對應之中速運轉模式。是以,風扇53a、53b將轉速調降為中速,冷空氣輸送至電池模組5A內之速度因而減緩,以減緩電池模組5A之降溫速度,並維持其工作溫度。Please also refer to Figure 5, Figure 6A, Figure 6B and Figure 7. As mentioned above, when the
反之,若空調裝置3仍處於冷卻模式,且電池模組5A之偏差值為一負數,且高於預定值(5℃)時,則代表該電池模組5A之工作溫度與基準溫度(即第二平均溫度)之偏差值已降至超過預定值(即5℃)以上,即電池模組5A之工作溫度低於基準溫度(第二平均溫度)5℃以上時,中央控制模組4將傳送低速運轉指令至電池模組5A,控制單元52進一步將低速運轉指令傳送至風扇組53,以啟動低速運轉模式,使風扇53a、53b低速運轉,使冷空氣少量進入電池模組5A中,以降低冷卻能力。Conversely, if the
於另一實施例中,若空調裝置3係處於加熱模式,即其輸出熱空氣,且電池模組5B之偏差值為一正數,並高於預定值(5℃)時,則中央控制模組4之核心處理器41將傳送一低速運轉指令至電池模組5B。電池模組5A之控制單元52將依據此低速運轉指令,使風扇組53啟動相對應之低速運轉模式,使風扇53a、53b低速運轉,使熱空氣少量地進入電池模組5B中,以降低增溫能力。倘若,電池模組5B之偏差值為一負數,且高於預定值(5℃)時,則代表電池模組5B之工作溫度低於基準溫度(第二平均溫度)5℃以上時,中央控制模組4將傳送高速運轉指令至電池模組5B,控制單元52將高速運轉指令傳送至風扇組53,以啟動高速運轉模式,使風扇53a、53b高速運轉,使熱空氣大量且快速地進入電池模組5B中,以對電池模組5B內之複數個電池51進行增溫,俾提升電池模組5B之工作溫度,以使該偏差值調整至預定值內。In another embodiment, if the
如前所述,若空調裝置3處於加熱模式,但電池模組5B之工作溫度與基準溫度(即第二平均溫度)之偏差值低於預定值(即5℃)時,則代表電池模組5B之工作溫度處於第二平均溫度的容受範圍內,是以中央控制模組4即傳送中速運轉指令至電池模組5B,使電池模組5B之風扇組53啟動對應之中速運轉模式,以減緩熱空氣輸送至電池模組5B內之速度,進而減緩電池模組5B之增溫速度,並維持其工作溫度。As mentioned above, if the
由此可見,於本實施例中,複數個電池模組5A、5B、5C、5D…係為動態之熱管理,且透過中央控制模組4隨時對工作溫度產生離異(即偏差值大於預定值)之電池模組5A、5B等進行溫度控管,藉由風扇運轉指令使該等電池模組5A、5B之風扇組53進行不同的風速調整,並搭配空調裝置3提供之工作模式,以降低或是提升電池模組5A、5B之工作溫度,並使其拉回平均值,進而維持複數個電池模組5A、5B、5C、5D…之溫度一致性。同時亦提升每一電池模組5內之複數個電池51之均溫性,進而可有效延長該等電池51之使用壽命,並可防止總電容量的損失。It can be seen that, in this embodiment, a plurality of
綜上所述,本案提供了一種電池均溫控制系統,藉由中央控制模組依據環境溫度傳送溫控指令至空調裝置,以啟動一冷源或一熱源,同時將機櫃中複數個電池模組傳送來之複數個工作溫度資訊,進行比對運算,並各別傳送風扇運轉指令至每一個電池模組,使每一個電池模組之風扇組對應啟動一運轉模式,對電池模組內之複數個電池進行降溫或增溫,以隨時調整每一電池模組之工作溫度,俾達一動態溫度平衡。是以,機櫃中的每一個電池模組可有效提升冷卻效率或加熱效率,並提升複數個電池之溫度一致性,以延長電池壽命、並阻止總電容的損失,並增加產品的可靠度。本案得由熟習此技術之人士任施匠思而為諸般修飾,然皆不脫如附申請專利範圍所欲保護者。In summary, this case provides a battery temperature uniform control system.
