车辆的电源装置
摘要：
一种车辆的电源装置，通过使其具有冗余性且抑制电池间的电压差而在开关切换时抑制过电流流过开关。一种车辆的电源装置(S)，具备：具有第1蓄电元件(53A)的第1蓄电装置(50A)、具有第2蓄电元件(53B)的第2蓄电装置(50B)、对将上述第1蓄电装置(50A)与上述第2蓄电装置(50B)并联连接的状态和将上述第1蓄电装置(50A)与上述第2蓄电装置(50B)断开的状态之间进行切换的开关(SW1)、以及开关控制部(70)，上述第1蓄电元件(53A)和上述第2蓄电元件(53B)是在SOC-OCV特性中具有平坦区域的蓄电元件，上述开关控制部(70)在上述第1蓄电元件(53A)和上述第2蓄电元件(53B)在上述SOC-OCV特性中处于平坦区域时执行上述开关(SW1)的从关闭到打开的切换。
摘要（英）：

A power supply device for a vehicle, which suppresses an overcurrent flowing through a switch when a switch is switched by making it redundant and suppressing a voltage difference between the batteries. A power supply device (S) for a vehicle includes: a first energy storage device (50A) having a first energy storage element (53A); a second energy storage device (50B) having a second energy storage element (53B); a switch (SW1) which switches between a state in which the first energy storage device (50A) and the second energy storage device (50B) are connected in parallel and a state in whichthe first energy storage device (50A) and the second energy storage device (50B) are separated from each other; and a switch controller (70). Each of the first energy storage element (53A) and the second energy storage element (53B) is an energy storage element having an SOC-OCV characteristic having a flat region thereon, and the switch controller (70) switches the switch from an off-state to anon-state when each of the first energy storage element (53A) and the second energy storage element (53B) is in the flat region of the SOC-OCV characteristic.
