A terminal apparatus detachably mounted on a battery module assembly made up of module units which are formed as aggregates of a plurality of cells and accommodated in a battery case through its open end. The apparatus has a computer which is programed to acquire state of the battery module assembly, to communicate acquired state of the battery module assembly to outside, and to connect or disconnect output of the battery module assembly to or from a load such as a vehicle electric motor, a factory electrical machine tool, home lighting fixtures and a construction machine electric motor by means of switch. The computer is further programed to detect change of the load and to switch output of the battery module assembly in accordance with changed load when the change of the load is detected.

Terminal apparatus for battery module assembly

A power supply apparatus includes a battery pack for a motor vehicle, and a power interface part that connects the battery pack and a plurality of electrical devices. The power interface part includes a battery-side connector, and a branch connector apparatus. The branch connector apparatus includes a joining part for connection lines, a fuse, a housing, and a connector. A guided part is provided on an outer side surface of the housing. The battery pack includes a slot part allowing the branch connector apparatus to be inserted and extracted. The battery-side connector is provided in the slot part. A guiding part extending along an insertion and extraction direction is provided on an inner side surface of the slot part. The guided part is guided along an extension direction of the guiding part by the guiding part.

Power supply apparatus and branch connector apparatus

A power supply apparatus includes a battery pack for an electric vehicle, and an interface unit that couples the battery pack and a plurality of electrical devices. The interface unit includes a branch connector provided with a coupling unit and a plurality of fuses. The coupling unit allows coupling wires to join. Each of the coupling wires is coupled to a corresponding one of electrical devices. Each of the plurality of fuses is disposed in a corresponding one of coupling wires. The interface unit also includes a battery pack connector that is able to be coupled to the branch connector. In a state in which the branch connector is coupled to the battery pack connector, the power supply apparatus is configured to be able to supply electric power from the battery pack to each of the plurality of electrical devices via the coupling unit.

Power supply apparatus

A battery module includes: a cell laminated body; a first and a second end plates which are provided at both end portions of the cell laminated body; and a sensor device which is mounted on a mounting surface and detects the voltage of each cell in the cell laminated body. The sensor device includes: a sensor device body; and a sensor fixing portion which is fixed to the first end plate by a fastening member. In the perpendicular direction, an end surface of the fastening member is located to be lower than or equal to an end surface of the sensor device body, the mounting surface of the cell laminated body is located to be lower than a bottom surface of the sensor fixing portion, and an end surface of the first end plate is located to be lower than the mounting surface of the cell laminated body.

A battery module includes: a cell-stacked body constituted by stacking a plurality of cells; a plurality of bus bars, each of which connects terminals of adjacent cells; and a sensor device configured to detect a voltage of each cell. The sensor device is disposed above the plurality of bus bars disposed on an upper surface of the cell-stacked body as viewed from a width direction perpendicular to a stacking direction and an up-down direction, and includes a connector having a connection portion in the width direction. Each of the bus bars has a bent portion protruding upward between the cells to be connected. The connector is disposed between the bent portions of adjacent bus bars in the stacking direction, and a lower surface of the connector is provided at a position lower than an upper portion of the bent portion in the up-down direction.

Battery module

A battery module includes: a cell-stacked body constituted by stacking a plurality of cells; and a sensor device configured to detect a voltage of each cell. The sensor device is disposed on an upper portion of the cell-stacked body. The sensor device is provided with a sensor bulging portion which bulges downward, and the upper portion of the cell-stacked body is provided with a low-height portion accommodating the sensor bulging portion.

A first range, a second range, and a third range are determined for a state-of-charge associated with a battery. The second range is determined based on a first set of information. The third range is determined based on a second set of information different from the first set of information. A map including a first zone associated with the first range, a second zone associated with the second range, and a third zone associated with the third range is displayed.

Method and system for reducing range anxiety

In a power supply unit disposed below a floor behind a seat, battery modules are disposed in a lower position, and a DC/DC converter and a motor driving inverter are disposed side by side in a vehicle width direction above the battery modules. Thus, cooling air flowing from the front side to the rear side of a vehicle body is divided into upper and lower portions to cool in parallel the DC/DC converter and the motor driving inverter on the upper side and the battery modules on the lower side. Thus, it is possible to simplify a passage of the cooling air to reduce the size of the entire power supply unit, and improve mountability of the power supply unit on the vehicle body. Also, it is possible to apply low temperature cooling air, before heat exchange, to the battery module, the DC/DC converter, and the motor driving inverter.
