Abstract: An assembled battery is formed by combining battery modules. Each battery module includes at least one battery cell and a rectangular box-shaped case that accommodates the at least one battery cell. The battery modules include a first battery module and a second battery module located adjacent to each other. The case of each of the first battery module and the second battery module includes an opposing side surface that is opposed to one of the first battery module and the second battery module. Each opposing side surface includes projections, which are laid out in rows, and ribs, which extend parallel to the layout direction of the projections. The ribs are smaller in height than the first projections. The ribs include connection ribs that connect the projections located in a predetermined range in the layout direction of the projections.

Abstract: A control device for an onboard engine is configured to control the oil discharge pressure of an oil pump and execute, when determining that there may be an abnormality in the control of the oil discharge pressure, a change process that increases the target discharge pressure to a value that is greater than that before it is determined that there may be an abnormality in the control. When a discharge pressure sensor value in a situation in which the discharge pressure is being controlled based on the target discharge pressure increased through execution of the change process does not become greater than or equal to a discharge pressure threshold, the control device sets an upper limit for the engine rotation speed and increases the upper limit as the discharge pressure sensor value increases.

Abstract: A cooling apparatus for an internal combustion engine includes a pump, a radiator, a flow rate adjustment valve, a bypass passage, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases. The valve member rotates in a valve-opening direction in which the open degree increases when a pressure difference increases between positions upstream and downstream of the valve member in a flow direction of coolant in the circulation circuit and rotate in the valve-closing direction when the pressure difference decreases. The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.

Abstract: A cooling device includes an inner passage, an outer passage, an engine-driven pump, an electromagnetic control valve, and a driving circuit that regulates current flowing through the electromagnetic control valve by activating and deactivating a switching element. A cooling controller for the cooling device includes a processing circuit configured to execute an operation process for operating, when the engine-driven pump is driven, the switching element by setting a duty cycle of an activation time to a switching cycle, which is a reciprocal of a switching frequency of the switching element, to be a larger value when a temperature of the internal combustion engine is low than when the temperature is high and a cycle varying process for setting a longer switching cycle when the temperature of the internal combustion engine is less than a preset temperature than when the temperature is greater than or equal to the preset temperature.

Abstract: A vehicle includes: a floor panel; and a battery pack mounted under the floor panel. The battery pack includes: a plurality of cell stacks; a housing case including a bottom portion and configured to house the plurality of cell stacks; and a plurality of support members provided on the bottom portion and spaced apart from one another. When a front region, a central region and a rear region are defined in a bottom view of the housing case, a ratio of a total area where the support member is provided in the central region to an area of the central region is higher than a ratio of a total area where the support member is provided in the rear region to an area of the rear region.

Abstract: A device seating a valve body with the aid of an urging force of a spring by stopping the operation of a pump, changes over an energization state of a coil of at least one of the liquid shutoff valves which is changed over to the closed-valve state where the coil is energized, and then resumes the operation of the pump. Upon detecting the start of operation of the pump, a valve control unit causes a pump control unit to perform opening-closing force-feed control, where an amount of the cooling liquid force-fed by the pump is set to an amount within such a range that the valve body of the liquid shutoff valves whose coil is energized is not displaced in a valve-opening direction while the valve body of the liquid shutoff valves whose coil is not energized is displaced in the valve-opening direction.

Abstract: An electricity storage system includes a plurality of electricity storage elements, a partition member, a pair of end plates, and a plurality of coupling members. The case includes a flat surface that has a first region opposed to a positive-electrode active material layer and a negative-electrode active material layer of a power generation element, and a second region other than the first region. The partition member is disposed between two electricity storage elements adjacent to each other in the predetermined direction. The pair of end plates is disposed in positions sandwiching the plurality of electricity storage elements in the predetermined direction such that the pair of end plates applies a constraint force to the plurality of electricity storage elements. The constraint force acting on the second region is larger than the constraint force acting on the first region.

Abstract: A cooling apparatus includes a circulation circuit, a pump, a flow rate adjustment valve, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a stopper that moves between a restriction position and a retraction position. The controller is configured to execute, when maintaining the open degree of the flow rate adjustment, a preparatory process of moving the stopper to the restriction position after arranging the stopper at the retraction position and arranging the valve member further in the valve-closing direction than the stopper through control of the pump discharge amount.
