技術說明

一種串聯電池開關模組包含一電池、一雙向開關、一單向限流元件及一單向開關，該電池具有一正極端及一負極端，該雙向開關之兩端分別電性連接該電池之該正極端及一第一節點，該單向限流元件之兩端分別電性連接該第一節點及一第二節點，該單向開關之兩端分別電性連接該第一節點及該第二節點，藉由控制該雙向開關及該單向開關可讓該電池操作於正常充放電模式或是旁路充放電模式，使得多電池串聯使用時，可依據各自狀態決定參與充放電時間，以延續其使用壽命。 A series connected battery switch module includes a battery, a bidirectional switch, a unidirectional current limiting component and a unidirectional switch. The battery has a positive terminal and a negative terminal. The two ends of the bidirectional switch are electrically connected to the positive terminal of the battery and a first node respectively. The two ends of the unidirectional current limiting component are electrically connected to the first node and a second node respectively. The two ends of the unidirectional switch are electrically connected to the first node and the second node respectively. The present patent controls the bidirectional switch and the unidirectional switch to operate the battery in a normal charging/discharging mode or a bypass charging/discharging mode, so that when multiple batteries are used in series, the charging and discharging time can be determined according to their respective states to extend their lifetime.
