Description

バッテリ装置50に接続される充電器CHの電圧は、二次電池SCの電圧(例えば3.8V)よりも大きい電圧であればよいため、様々な電圧の充電器を用いることができる。したがって、二次電池SCの電圧よりも遥かに大きい電圧(例えば20V)の充電器が使用されることもある。 Since the voltage of the charger CH connected to the battery device 50 may be higher than the voltage of the secondary battery SC (for example, 3.8V), chargers of various voltages can be used. Therefore, a charger having a voltage much higher than the voltage of the secondary battery SC (for example, 20 V) may be used.

第1の充放電制御装置11は、第1の充放電制御回路110(「充電器側の充放電制御回路」ともいう)と、放電制御FET121と、充電制御FET122と、過電流検出用抵抗130と、抵抗140とを備えている。 The first charge/discharge control device 11 includes a first charge/discharge control circuit 110 (also referred to as a “charger-side charge/discharge control circuit”) , a discharge control FET 121, a charge control FET 122, and an overcurrent detection resistor 130. And a resistor 140.
