    Abstract: An energy storage apparatus includes: an energy storage device which is connected to a vehicle load and a vehicle power generator; a current interrupt device that causes the energy storage device and the vehicle load as well as the energy storage device and the vehicle power generator to be in a conduction state or in an interruption state; a voltage detection unit that detects voltage of the energy storage device; and a control unit. The control unit executes: a switching instruction process in which, when determining that the electric storage device will reach an overcharge state on the basis of the voltage, the control unit issues an interruption switching instruction to the current interrupt device; and an interruption maintaining process in which, when the number of times of the switching instruction process exceeds a predetermined value, the control unit issues an instruction to maintain the interruption state.

    Abstract: An electric storage apparatus includes an output terminal configured to be electrically connected to a system including an engine, an electric storage device, a monitoring apparatus including a detector and a controller, and a relay disposed between the output terminal and the electric storage device. The detector is configured to detect a variation value corresponding to an amount of charge of the electric storage device. The controller is configured to determine whether the variation value is equal to or lower than an opening threshold, and execute an opening process to switch the relay from a closed state to an open state if the variation value is equal to or lower than the opening threshold. The opening threshold is larger than an engine activation low-threshold by a predetermined value. The engine activation low-threshold is a lowest level of the amount of charge at which the engine is able to be started.

    Abstract translation: 一种蓄电装置，包括：输出端子，被配置为电连接到包括发动机的系统，蓄电装置，包括检测器和控制器的监视装置，以及设置在所述输出端子和所述蓄电装置之间的继电器。 检测器被配置为检测对应于蓄电装置的充电量的变化值。 控制器被配置为确定变化值是否等于或低于打开阈值，并且如果变化值等于或低于打开阈值，则执行打开处理以将继电器从关闭状态切换到打开状态 。 开启阈值大于发动机启动低阈值预定值。 发动机启动低阈值是发动机能够启动的充电量的最低水平。

    Abstract: Provided is a management device (BMS 40) for an assembled battery 30 which uses a positive electrode active material containing lithium iron phosphate and having an electrically conductive layer formed on a surface thereof, the BMS 40 being provided with: a current sensor 43 which measures a current flowing through the assembled battery 30; a voltage sensor 45 which measures a voltage of the assembled battery 30; and a management unit 42. When a state in which the current value measured by means of the current sensor 43 is less than a reference value is defined as a pause state of the assembled battery 30, the management unit 42, when the assembled battery 30 has entered the pause state, performs: a discharge process (S101) for causing the assembled battery 30 to discharge; a post-discharge measurement process (S102) for measuring the voltage by means of the voltage sensor 45 after the assembled battery 30 has been discharged in the discharge process; and a first estimation process (S103) of estimating the SOC of the assembled battery 30 on the basis of the voltage measured in the post-discharge measurement process and OCV-SOC characteristics 62 after the discharge.
