摘要： A battery pack supplies an electrically driven treatment apparatus with an electric driving power, and includes: a stack limiting structure; a plurality of pouch cells, wherein the pouch cells are disposed in a stack, wherein the stack is disposed within the stack limiting structure; an outer temperature sensor, wherein the outer temperature sensor is disposed and configured for measuring an outer temperature of the stack outside the stack at an edge of the stack or the stack limiting structure, and/or outside the stack limiting structure; and a control device. The control device is configured for comparison of the measured outer temperature and/or a quantity based on the measured outer temperature to at least one temperature comparative value. The at least one temperature comparative value is a function of at least one of the pouch cells. The control device is configured for controlling the battery pack in response to a result of the comparison.

摘要： A power supply control device includes a control unit, and a power path that is connected to a primary external power system. If a connection state between the primary external power system and the power path is in a disconnected state, the control unit is configured to control power output of at least one power conditioner of at least one corresponding secondary external power generation unit, based on (a) an amount of power consumption of a specific load connected to the power supply control device through the power path, and (b) a power generation output of the secondary external power generation unit.

摘要： There is provided a power storage device including a plurality of modules each including secondary batteries, a charging switch that controls charging to the secondary batteries, a discharging switch that controls discharging of the secondary batteries, and a voltage measuring unit that measures a voltage of the module, and a switch control unit that controls one or both of the charging switch and the discharging switch. The modules are connected in parallel. The switch control unit maintains an on state of the discharging switch for at least one of the modules for a predetermined period, and controls the charging switch of the module in which a maximum module charging current estimated based on the voltage of the module is a predetermined value or less, to be in an on state.
