再者，當該第一電池芯302與該第二電池芯304的電壓接近相等且等於一預設電壓時，該二次電池充放電裝置10即進入定電壓充電模式，適度降低該主充電電流A0、該第一個別充電電流A1及該第二個別充電電流A2，此時該主控制模組102仍每隔該預定時間即分別透過該第一隔離型介面112及該第二隔離型介面118詢問該第一電池充電偵測模組110及該第二電池充電偵測模組116以得知該第一電池芯302的電壓、該第二電池芯304的電壓、該第一個別充電電流A1及該第二個別充電電流A2。此時若該第一個別充電電流A1及該第二個別充電電流A2等於或小於一預設截止充電電流，則該二次電池充放電裝置10停止對該電池封包30充電，並且該二次電池充放電裝置10顯示該電池封包30已充飽 電；或此時若有部份電池芯的個別充電電流等於或小於該預設截止充電電流(已充飽)，但有部份電池芯的個別充電電流大於該預設截止充電電流(未充飽)，則該主控制模組102控制該主電池充電模組104及達到充飽的電池芯對應的電池充電偵測模組停止充電，而未充飽的電池芯對應的電池充電偵測模組繼續充電，直到全部電池芯達到充飽，該二次電池充放電裝置10停止對該電池封包30充電，並且該二次電池充放電裝置10顯示該電池封包30已充飽電。 Moreover, when the voltages of the first battery core 302 and the second battery core 304 are nearly equal and equal to a predetermined voltage, the secondary battery charging and discharging device 10 enters a constant voltage charging mode to moderately reduce the main charging current. A0, the first individual charging current A1 and the second isolated charging current A2. At this time, the main control module 102 transmits the first isolated interface 112 and the second isolated interface 118 again every predetermined time. The first battery charging detection module 110 and the second battery charging detection module 116 are queried to know the voltage of the first battery core 302, the voltage of the second battery core 304, and the first individual charging current A1. And the second individual charging current A2. At this time, if the first individual charging current A1 and the second individual charging current A2 are equal to or less than a predetermined off charging current, the secondary battery charging and discharging device 10 stops charging the battery pack 30, and the secondary battery The charging and discharging device 10 indicates that the battery pack 30 is fully charged Electric; or if some of the battery cells have a specific charging current equal to or less than the preset off charging current (full), but some of the cells have individual charging currents greater than the preset off charging current (not charged) The main control module 102 controls the main battery charging module 104 and the battery charging detection module corresponding to the fully charged battery core to stop charging, and the battery charging detection mode corresponding to the unfilled battery core The group continues to charge until all of the battery cells have reached fullness, the secondary battery charge and discharge device 10 stops charging the battery pack 30, and the secondary battery charge and discharge device 10 indicates that the battery pack 30 has been fully charged.
例如，若該第一個別充電電流A1等於或小於該預設截止充電電流(已充飽)，但該第二個別充電電流A2大於該預設截止充電電流(未充飽)，則該主控制模組102控制該主電池充電模組104及該第一電池充電偵測模組110停止充電，而該第二電池充電偵測模組116則繼續對該第二電池芯304充電，直到該第二電池芯304被充飽，該二次電池充放電裝置10停止對該電池封包30充電，並且該二次電池充放電裝置10顯示該電池封包30已充飽電。 For example, if the first individual charging current A1 is equal to or less than the preset off charging current (filled), but the second individual charging current A2 is greater than the preset off charging current (not fully charged), the main control The module 102 controls the main battery charging module 104 and the first battery charging detection module 110 to stop charging, and the second battery charging detection module 116 continues to charge the second battery core 304 until the first The battery core 304 is fully charged, the secondary battery charge and discharge device 10 stops charging the battery pack 30, and the secondary battery charge and discharge device 10 displays that the battery pack 30 is fully charged.

Moreover, when the power source 202 is greater than the voltage of the battery pack 30 (ie, performing standard charging), the main battery charging module 104 performs the main charging subroutine on the battery pack 30, and the first battery charging detection mode The group 110 and the second battery charge detection module 116 respectively perform the balanced charging subroutine for the first battery core 302 and the second battery core 304; when the power source 202 is not greater than the voltage of the battery package 30 (ie, The main battery charging module 104 does not perform the main charging subroutine on the battery pack 30, and the first battery charging detecting module 110 and the second battery charging detecting module 116 respectively The first battery core 302 and the second battery core 304 are charged (the main charging subroutine and the balanced charging subroutine are performed).

再者，以下內容以範例敘述該主控制模組102如何分析計算各電池芯的現況資料以控制該主電池充電模組104以設定該主充電電流A0，以及該主控制模組102如何分析計算各電池芯的現況資料以控制該些電池充電偵測模組以設定該些個別充電電流：假設該電池封包30係為LiFePO4電池芯，具有四個電池芯以串聯成為一個電池封包，其特性參數假設為：電池芯標稱電壓為3.3V，標稱充電電壓為3.6V，標稱標準充電電流為1.0C(C-rate)，本發明之該主充電電流A0可設定為0~1.0C，該些個別充電電流可設定0~0.5C。 Furthermore, the following content describes how the main control module 102 analyzes the current status data of each battery cell to control the main battery charging module 104 to set the main charging current A0, and how the main control module 102 analyzes and calculates. The current status of each battery cell is used to control the battery charging detection modules to set the individual charging currents: assuming that the battery package 30 is a LiFePO4 battery core, having four battery cells connected in series to form a battery package, and its characteristic parameters The assumption is: the battery core nominal voltage is 3.3V, the nominal charging voltage is 3.6V, and the nominal standard charging current is 1.0C (C-rate). The main charging current A0 of the present invention can be set to 0~1.0C. These individual charging currents can be set from 0 to 0.5C.

V.
設定該主充電電流A0為1.0C，電池芯電壓值最高者對應的電池充電偵測模組以0.1C個別充電電流充電，電壓每差0.01V時增加0.1C：3號電池芯的3.177V電壓最高，所對應的電池充電偵測模組將以0.1C個別充電電流充電；1號電池芯為3.174V，故設定對應電池充電偵測模組以0.1C個別充電電流充電；2號電池芯3.165V與最高電壓兩者差超過0.01V，故對應的電池充電偵測模組係以0.2C個別充電電流充電；4號電池芯3.151V與最高電壓兩者差超過0.02V，則對應的電池充電偵測模組以0.3C個別充電電流充電。當各電池芯電壓值達到3.6V時，且於誤差範圍內，則該主電池充電模組104進入定電壓充電模式，各電池充電偵測模組的個別充電電流降為零；於定電壓充電模式下，若各電池芯電壓值出現電壓差變大時，該主控制模組102會再控制各電池充電偵測模組進行平衡充電。 The main charging current A0 is set to 1.0C, and the battery charging detection module corresponding to the highest battery voltage value is charged with 0.1C individual charging current, and the voltage is increased by 0.1C when the voltage is 0.01V: 3.177V of the 3rd battery core. The highest battery charging detection module will be charged with 0.1C individual charging current; the No.1 battery core is 3.174V, so the corresponding battery charging detection module is set to charge with 0.1C individual charging current; No. 2 battery core 3.165 The difference between V and the highest voltage exceeds 0.01V, so the corresponding battery charge detection module is charged with 0.2C individual charging current; if the difference between the 3.151V and the highest voltage of the 4th battery core exceeds 0.02V, the corresponding battery is charged. The detection module is charged with a 0.3C individual charging current. When the voltage value of each battery cell reaches 3.6V, and within the error range, the main battery charging module 104 enters the constant voltage charging mode, and the individual charging current of each battery charging detection module drops to zero; In the mode, if the voltage difference between the battery voltage values becomes large, the main control module 102 controls the battery charging detection modules to perform balanced charging.
