A bus bar module includes: a case extending from a first end to a second end; a bus bar; and electric wires. The case includes first and second electric wire routing groove portions provided in parallel, electric wire passing portions bridged between the first and second electric wire routing groove portions, and an electric wire take-out portion which is provided in the first electric wire routing groove portion and from which the electric wires are drawn toward the second end. At least a part of the electric wires is routed from a position of the second electric wire routing groove portion closer to the second end than the electric wire take-out portion, through an electric wire passing portion provided closer to the one end than the electric wire take-out portion, to the electric wire take-out portion.

Bus bar module

A bus bar module includes: a case attached to a battery assembly including a plurality of single cells; a bus bar supported by the case and electrically connected to electrodes of the plurality of single cells of the battery assembly; and a plurality of electric wires routed in the case. The plurality of electric wires include: a plurality of voltage detection electric wires connected to the bus bar, and a temperature measurement electric wire connected to a thermistor configured to measure a temperature of at least one of the plurality of single cells. The case includes: an electric wire routing groove portion in which the plurality of voltage detection electric wires are routed, and a thermistor attachment portion to which the thermistor is attached. The thermistor attachment portion is provided in the electric wire routing groove portion.

Thermistor attachment configuration for a bus bar module

An electricity storage device includes: a first battery stack () including a plurality of cells that are aligned in a first direction; a second battery stack (to) including a plurality of cells that are aligned in a second direction different from the first direction, the second battery stack being placed under the first battery stack; and a duct for coolant. The duct is disposed along the first battery stack and is positioned between the first battery stack and the second battery stack.

Electricity storage device and vehicle

Provided are: a first-group accommodation part () and a second-group accommodation part () in each of which accommodation parts () each of which accommodates at least one of a bus bar (), a terminal (), and an electric wire () connected to the terminal () are arranged; a linkage part () linking the first-group accommodation part () and the second-group accommodation part () to each other; and an electric wire routing part () provided in the linkage part () and accommodating the electric wires ().

Electric wire routing structure for bus bar module

A power storage apparatus includes a power storage module having a plurality of power storage elements which are aligned in one direction; a device placed adjacently to the power storage module in the direction of the alignment of the power storage elements; a high-voltage cable used in charge and discharge of the power storage module; and a support structure configured to support the high-voltage cable at a plurality of points to position the high-voltage cable along a reference path. The high-voltage cable is configured to electrically connect an electrode terminal of the power storage module to the device. The electrode terminal is one of two electrode terminals of the power storage module and is located on a farther side of the power storage module from the device.
