參閱圖7至圖11，本發明電池連接模組10之一第二實施例與該第一實施例的差異在於，於第二實施例中每一採溫片43的第二端部432所設置的採溫點為該電池組6的電池61的殼體612。每一採溫片43還具有一體地垂直連接於該第一端部431與第二端部432的一連接部433，該第二端部432低於該第一端部431，採溫片43的連接部433及第二端部432穿過匯流件2及承載盤1且以例如焊接方式將第二端部432設置於該電池組6的電池61的殼體612。並且，與該等採溫片43位置相對應的匯流件2各自形成有供採溫片43的連接部433及第二端部432穿過的一避位凹部23，並且該承載盤1的盤體11形成有供採溫片43的連接部433及第二端部432穿過的多個避位穿孔117。需說明的是，在其他變化實施態樣中，只要匯流件2與該承載盤1的盤體11不遮擋採溫片43，所述匯流件2也可以不形成避位凹部23且該承載盤1的盤體11也可以不形成避位穿孔117，不以此為限。透過該第二端部432直接地接觸電池61的殼體612以採集溫度，進一步地提高了溫度採集的速度並縮短溫度響應時間。Referring to FIGS. 7 to 11, the difference between the second embodiment of a battery connection module 10 of the present invention and the first embodiment is that the second end 432 of each temperature collecting piece 43 is provided in the second embodiment The temperature collection point is the casing 612 of the battery 61 of the battery pack 6. Each temperature collecting piece 43 also has a connecting portion 433 integrally and vertically connected to the first end portion 431 and the second end portion 432, the second end portion 432 is lower than the first end portion 431, and the temperature collecting piece 43 The connecting portion 433 and the second end portion 432 of the battery pass through the busbar 2 and the carrier plate 1 and the second end portion 432 is disposed on the casing 612 of the battery 61 of the battery pack 6 by, for example, welding. In addition, the confluence members 2 corresponding to the positions of the temperature collecting pieces 43 are respectively formed with a position-relief recess 23 through which the connecting portion 433 and the second end portion 432 of the temperature collecting piece 43 pass, and the plate of the carrier plate 1 The body 11 is formed with a plurality of escape holes 117 through which the connecting portion 433 and the second end portion 432 of the temperature collecting sheet 43 pass. It should be noted that, in other modified implementations, as long as the manifold 2 and the plate body 11 of the carrier plate 1 do not block the temperature collection sheet 43, the confluence member 2 may not form the avoidance recess 23 and the carrier plate The disk body 11 of 1 may not be formed with the avoiding holes 117, and it is not limited thereto. The second end 432 directly contacts the casing 612 of the battery 61 to collect the temperature, which further increases the speed of temperature collection and shortens the temperature response time.

綜上所述，於本發明中所述採溫片43沒有連接電路板的電路跡線，不作為採集電壓之用而僅作為採集溫度之用，如此可避免因同時採集電壓而造成的溫度採集失真。再者，由於鄰近所述溫度感測件44的所述採溫片43採用導熱性優於所述導電片42的相異材質，能夠增加所述溫度感測件44的溫度採集的準確度，並縮短溫度響應時間。In summary, in the present invention, the temperature collecting chip 43 is not connected to the circuit traces of the circuit board, and is not used for collecting voltage but only for collecting temperature. This can avoid the distortion of temperature collection caused by collecting voltage at the same time. . Furthermore, since the temperature collecting sheet 43 adjacent to the temperature sensing element 44 is made of a different material with better thermal conductivity than the conductive sheet 42, the accuracy of the temperature collection of the temperature sensing element 44 can be increased. And shorten the temperature response time.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
