Description

充電電池管理系統Rechargeable battery management system

本發明相關於一種電池充電裝置，特別是相關於一種充電電池管理系統。The invention relates to a battery charging device, in particular to a rechargeable battery management system.

隨著科技的進步，對於能源使用的需求逐年增加，而無論是石油燃料、核能之類的不可再生能源或是風能、太陽能、潮汐能、地熱能之類的可再生能源，主要都是轉換成電能使用。因此，作為電能之儲存與攜帶之電池愈來愈受到重視，其中又以能夠被再次充電的充電電池尤其受到歡迎。With the advancement of technology, the demand for energy use has increased year by year. Whether it is non-renewable energy sources such as petroleum fuels, nuclear energy, or renewable energy sources such as wind energy, solar energy, tidal energy, and geothermal energy, mainly conversion Into electrical energy. Therefore, batteries that are used to store and carry electrical energy are receiving more and more attention, and rechargeable batteries that can be recharged are especially popular.

一般而言，用於對充電電池進行充電的電池充電裝置，其常見的充電方式有串聯充電之方式或者是並聯充電之方式。串聯充電之方式是指將複數個充電電池串聯，而一併對所有充電電池流入同一充電電流。然而，由於各個充電電池之內電阻及殘存電量並不會完全相同，故在串聯充電時的充電電池之電壓會出現個別差異，充電的速度也因此不同。如此一來，可能造成一部分的充電電池充電飽和時，其它的充電電池卻過度充電或尚未飽和的情況，長期下來會令部分充電電池的壽命縮短。並聯充電之方式是指將複數個充電電池並聯，並將充電電流分配給所有充電電池而同時進行充電。並聯充電之方式需要很大的充電電流，控制電路更為複雜，也使得電池充電裝置的成本較高，並且因充電電池的個體差異，實際上在並聯充電時並無法將充電電流作理想的均勻分配，同樣會有充電狀態不一致的問題存在。Generally speaking, battery charging devices for charging rechargeable batteries generally have a serial charging method or a parallel charging method. The method of series charging means that a plurality of rechargeable batteries are connected in series, and the same charging current flows into all rechargeable batteries in a pair. However, since the internal resistance and remaining power of each rechargeable battery are not completely the same, the voltage of the rechargeable battery when charging in series will be different, and the charging speed will be different. As a result, when some rechargeable batteries are fully charged, other rechargeable batteries are overcharged or not yet saturated, which will shorten the life of some rechargeable batteries in the long run. The parallel charging method refers to connecting a plurality of rechargeable batteries in parallel and distributing the charging current to all rechargeable batteries while charging simultaneously. The parallel charging method requires a large charging current, the control circuit is more complicated, and the cost of the battery charging device is higher, and due to the individual differences of the rechargeable batteries, in fact, the charging current cannot be ideally uniform during parallel charging Distribution, there will also be the problem of inconsistent charging status.

如第1圖所示，在本實施例的充電電池管理系統100中，更包含一過電流保護電路51及一過電壓保護電路52。該過電流保護電路51連接於該電池充電電路2，用於感測並限制該串聯充電模式之充電電流，以防止過電流充電。該過電壓保護電路52連接於該電池充電電路2，用於感測並限制該跳充充電模式之充電電壓，以防止過電壓充電。As shown in FIG. 1, the rechargeable battery management system 100 of this embodiment further includes an overcurrent protection circuit 51 and an overvoltage protection circuit 52. The overcurrent protection circuit 51 is connected to the battery charging circuit 2 for sensing and limiting the charging current of the series charging mode to prevent overcurrent charging. The overvoltage protection circuit 52 is connected to the battery charging circuit 2 for sensing and limiting the charging voltage in the skip charging mode to prevent overvoltage charging.

如第1圖所示，在本實施例的充電電池管理系統100中，更包含一顯示器6，連接於該充電控制電路3，用於顯示上述感測取得的各電壓、電流值，以方便隨時監控電池資訊。As shown in FIG. 1, the rechargeable battery management system 100 of this embodiment further includes a display 6 connected to the charging control circuit 3 for displaying the voltage and current values obtained by the above-mentioned sensing, so as to be convenient at any time Monitor battery information.

如第5圖所示，在本實施例中，該充電電池管理系統100在實際運作時，首先，對該充電電池B進行電壓感測（步驟S10），以判斷該充電電池B是否未達一電壓閾值而需要充電（步驟S20）。若為該充電電池B電壓不足而需要充電的情況（即，「是」），則執行串聯充電模式（步驟S30）。As shown in FIG. 5, in this embodiment, when the rechargeable battery management system 100 is actually in operation, first, voltage sensing is performed on the rechargeable battery B (step S10) to determine whether the rechargeable battery B has not reached one. The voltage threshold requires charging (step S20). If the rechargeable battery B has an insufficient voltage and needs to be charged (ie, YES), the series charging mode is executed (step S30).

在串聯充電模式時，如第3a圖所示，該電源切換電路1切換至連接於該定電流電源P1，該電池充電電路2切換至該串聯導通狀態，使複數個該充電電池B經由該電池充電電路2而串聯並導通於該電源切換電路1，以對串聯的複數個該充電電池B進行定電流充電。應注意的是，在串聯充電模式時所使用的充電電壓比串聯的複數個該充電電池B之額定電壓還低，故即使該充電電池B之電壓達到該充電電壓之大小，亦不會造成電池過度充電且藉此能抑制電池溫度上升。在串聯充電模式時，該電壓感測電路41感測該充電電池B之電壓（即，串聯總電壓），以判斷該充電電池B之電壓是否大於一預設的電壓閾值（步驟S40）。In the series charging mode, as shown in FIG. 3a, the power switching circuit 1 is switched to be connected to the constant current power supply P1, and the battery charging circuit 2 is switched to the series conduction state, so that a plurality of the rechargeable batteries B pass through the battery The charging circuit 2 is connected in series and connected to the power switching circuit 1 to perform constant current charging on a plurality of the rechargeable batteries B connected in series. It should be noted that the charging voltage used in the series charging mode is lower than the rated voltage of the plurality of rechargeable batteries B connected in series, so even if the voltage of the rechargeable battery B reaches the size of the charging voltage, it will not cause the battery Overcharge and thereby suppress the battery temperature rise. In the series charging mode, the voltage sensing circuit 41 senses the voltage of the rechargeable battery B (ie, the total series voltage) to determine whether the voltage of the rechargeable battery B is greater than a preset voltage threshold (step S40).

當該充電電池B之電壓大於該電壓閾值時，該串聯充電結束單元31便會結束該串聯充電模式，該充電控制電路3接著則執行電池休息模式（步驟S50）。如第2圖所示，此時不對該充電電池B充電，以舒緩該充電電池內部離子聚集於電極的情況。該電池休息模式的持續時間可為約三分鐘。When the voltage of the rechargeable battery B is greater than the voltage threshold, the series charging end unit 31 will end the series charging mode, and the charging control circuit 3 then executes the battery rest mode (step S50). As shown in FIG. 2, the rechargeable battery B is not charged at this time, so as to relieve the accumulation of ions inside the rechargeable battery at the electrode. The duration of the battery rest mode may be about three minutes.

在該電池休息模式結束後，則該充電控制電路3執行跳充充電模式（步驟S60），輪替地（例如，依第3b圖、第3c圖、第3d圖的順序）使個別的該充電電池B連接於該定電壓電源P2而進行充電。在跳充充電模式時，除了正在充電的該充電電池B以外，其餘的該充電電池B並不與電源導通，而處於休息狀態，有助於使剛充過電的該充電電池B做電池內離子的平衡，以在感測時得到更準確的感測值。此時，該電流感測電路42感測充電中的該充電電池B之電流，以判斷該充電電池B之電流是否達到一預設的電流閾值（步驟S70）。當該充電電池B之電流達到該電流閾值，該跳充充電結束單元32便會結束當下的該充電電池B的充電，而輪替至下一個該充電電池B而進行充電。此外，當對當下的該充電電池B之充電時間達到預設的一時間閾值時，亦會由該跳充充電輪替單元33結束當下的該充電電池B的充電，而輪替至下一個該充電電池B而進行充電。當所有的該充電電池B都充電飽和後，則該充電控制電路3結束跳充充電模式。After the battery rest mode ends, the charging control circuit 3 executes the skip charging mode (step S60), alternately (for example, in the order of FIG. 3b, FIG. 3c, and FIG. 3d) to individually charge The battery B is connected to the constant voltage power supply P2 and charged. In skip charging mode, except for the rechargeable battery B that is being charged, the remaining rechargeable battery B is not connected to the power supply, but is at rest, which helps to make the rechargeable battery B that has just been charged into the battery. Balance of ions to get more accurate sensed value during sensing. At this time, the current sensing circuit 42 senses the current of the rechargeable battery B during charging to determine whether the current of the rechargeable battery B reaches a preset current threshold (step S70). When the current of the rechargeable battery B reaches the current threshold, the skip charging end unit 32 will end the current charging of the rechargeable battery B and rotate to the next rechargeable battery B for charging. In addition, when the current charging time of the current rechargeable battery B reaches a preset time threshold, the current charging of the rechargeable battery B will be ended by the skip charging and charging rotation unit 33, and the next battery will be rotated. The battery B is charged and charged. When all the rechargeable batteries B are fully charged, the charging control circuit 3 ends the skip charging mode.

藉由上述結構，本發明的充電電池管理系統100能夠對充電電池B以定電壓串聯充電及定電流跳充充電之方式進行充電，藉此可確保對充電電池B之快速充電、電池充電飽和，並防止過度充電的情況發生，以有效地管理充電電池B。再者，在本發明的實施例中，在兩次的充電之間可進一步加入電池休息的時間，能夠防止充電電池內部離子因前次充電聚集於電極而影響下次充電之執行，以確保能準確地將充電電池B充電飽和。With the above structure, the rechargeable battery management system 100 of the present invention can charge the rechargeable battery B in a manner of constant voltage series charging and constant current skip charging, thereby ensuring fast charging of the rechargeable battery B and saturation of the battery charge. And prevent the occurrence of overcharging to effectively manage the rechargeable battery B. In addition, in the embodiment of the present invention, a battery rest time can be further added between the two charges, which can prevent the internal ions of the rechargeable battery from being concentrated on the electrode due to the previous charge and affecting the execution of the next charge, to ensure that Accurately charge the rechargeable battery B to saturation.
