一般來說,燃料電池會封裝於一密封殼體中而構成一電池裝置。電池裝置於出廠前會進行氣密檢測,以確保電池裝置的品質。不過由於目前電池裝置僅在出廠前進行氣密檢測,故若電池裝置在使用者的使用過程中發生漏氣的狀況,則目前無任何機制能夠發覺電池裝置的異常。Generally, a fuel cell is packaged in a sealed casing to form a battery device. The battery device will be tested for air tightness before leaving the factory to ensure the quality of the battery device. However, since the current battery device is only tested for airtightness before leaving the factory, if the battery device leaks during the user's use, there is currently no mechanism to detect the abnormality of the battery device.
本發明在於提供一種電池管理裝置,藉以即時發覺電池管理裝置之異常狀況。The present invention is to provide a battery management device, so as to detect the abnormal condition of the battery management device in real time.
本發明之一實施例所揭露之電池管理裝置包含一外殼及一電池本體。外殼具有一氣密空間。電池本體位於氣密空間。電路組件位於氣密空間,並電性連接於電池本體。電路組件包含一氣壓感測器,氣壓感測器用以感測氣密空間的氣壓。The battery management device disclosed in an embodiment of the present invention includes a casing and a battery body. The casing has an airtight space. The battery body is located in an airtight space. The circuit assembly is located in the airtight space and is electrically connected to the battery body. The circuit component includes an air pressure sensor, and the air pressure sensor is used for sensing the air pressure of the airtight space.
根據上述實施例之電池管理裝置,由於本實施例之電池管理裝置裝設有氣壓感測器,故電池管理裝置在使用者的使用過程中,會即時監控電池管理裝置的實際氣壓值,並據以判斷電池管理裝置是否發生異常狀況。According to the battery management device of the above-mentioned embodiment, since the battery management device of this embodiment is equipped with an air pressure sensor, the battery management device will real-time monitor the actual air pressure value of the battery management device during the use of the user, and according to To determine whether an abnormal condition occurs in the battery management device.
以上關於本發明內容的說明及以下實施方式的說明係用以示範與解釋本發明的原理,並且提供本發明的專利申請範圍更進一步的解釋。The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention, and provide further explanation of the scope of the patent application of the present invention.
請參閱圖1至圖2。圖1為根據本發明第一實施例所述之電池管理裝置的立體示意圖。圖2為圖1之分解示意圖。See Figures 1 to 2. FIG. 1 is a schematic perspective view of a battery management device according to a first embodiment of the present invention. FIG. 2 is an exploded schematic view of FIG. 1 .
本實施例之電池管理裝置10包含一外殼100、一電池本體200及一電路組件300。The
外殼100包含一容置殼體110及一蓋體120。電池本體200與電路組件300位於容置殼體110。蓋體120覆蓋容置殼體110,以令容置殼體110與蓋體120共同圍繞出一氣密空間S。此外,外殼100之容置殼體110具有一進氣口111及一排氣口112。進氣口111與排氣口112用以插接一氣體調節裝置(未繪示),如泵浦,以抽取氣密空間S內之氣體,或是將氣體灌入氣密空間S。The
在本實施例中,進氣口111與排氣口112係位於容置殼體110,但並不以此為限。在其他實施例中,進氣口與排氣口係位於蓋體。In this embodiment, the
在本實施例中,氣密空間S內的氣體僅為楕性氣体之其中一種,如氮氣,以便於後續檢測電池本體200的狀況,容後一併說明。此外,氣密空間S的一預設氣壓值大於一大氣壓,以避免外殼100發生漏氣時,外殼100外部的液體流入而影響電池本體200之運作。In the present embodiment, the gas in the airtight space S is only one of elliptic gases, such as nitrogen, so as to facilitate the subsequent detection of the condition of the
電池本體200位於氣密空間S。電池本體200包含多個電池單體210,這些電池單體210彼此電性連接,如串聯或並聯。The
電路組件300位於氣密空間S,並電性連接於電池本體200。電路組件300包含一電路板310、一氣壓感測器320及一控制器330。電路板310疊設於電池本體200之一側。氣壓感測器320與控制器330設置於電路板310遠離電池本體200之一側,且控制器330電性連接氣壓感測器320。氣壓感測器320用以感測氣密空間S的氣壓。The
當氣壓感測器320測得之一實際氣壓值大於氣密空間S內之一預設氣壓值,則控制器330判定電池本體200異常。詳細來說,當電池本體200的狀況良好時,氣密空間S內的實際氣壓會維持於預設氣壓值,但是當電池本體200的狀況異常,如電池化學反應所產生之氣體外洩時,則氣密空間S的實際氣壓會大於預設氣壓值。因此,當氣密空間S的實際氣壓大於預設氣壓值時,可透過抽氣設備將氣密空間S內之氣體抽出,並進行氣體成本分析,以判斷電池本體200的異常原因。在本實施例中,由於氣密空間S內的氣體例如僅為氮氣而非空氣。因此,如果氣密空間S中之氣體存在氮氣以外之氣體,則可更精確地分析並判斷電池本體200的異常原因。When an actual air pressure value measured by the
此外,當氣壓感測器320測得之一實際氣壓值小於氣密空間S內之一預設氣壓值,則控制器330判定外殼100的氣密性異常。由於本實施例之電池管理裝置10裝設有氣壓感測器320,故電池管理裝置10在使用者的使用過程中,會即時監控電池管理裝置10的實際氣壓值,並據以判斷電池管理裝置10是否發生異常狀況。In addition, when an actual air pressure value measured by the
根據上述實施例之電池管理裝置,由於本實施例之電池管理裝置裝設有氣壓感測器,故電池管理裝置在使用者的使用過程中,會即時監控電池管理裝置的實際氣壓值,並據以判斷電池管理裝置是否發生異常狀況。According to the battery management device of the above-mentioned embodiment, since the battery management device of this embodiment is equipped with an air pressure sensor, the battery management device will real-time monitor the actual air pressure value of the battery management device during the use of the user, and according to To determine whether an abnormal condition occurs in the battery management device.
此外,由於氣密空間內的氣體例如僅為僅為楕性氣体之其中一種,如氮氣,而非空氣。因此,如果氣密空間中之氣體存在氮氣以外之氣體,則可更精確地分析並判斷電池本體的異常原因。In addition, the gas in the airtight space is, for example, only one of the elliptic gases, such as nitrogen, instead of air. Therefore, if there is a gas other than nitrogen gas in the gas in the airtight space, the abnormal cause of the battery body can be more accurately analyzed and judged.
在本發明的一實施例中,本發明之技術係可應用於車載裝置,例如自駕車、電動車或半自駕車等等。In an embodiment of the present invention, the technology of the present invention can be applied to in-vehicle devices, such as self-driving cars, electric cars, or semi-self-driving cars.
雖然本發明以前述之諸項實施例揭露如上,然其並非用以限定本發明,任何熟習相像技藝者,在不脫離本發明之精神和範圍內,當可作些許之更動與潤飾,因此本發明之專利保護範圍須視本說明書所附之申請專利範圍所界定者為準。Although the present invention is disclosed above by the aforementioned embodiments, it is not intended to limit the present invention.
