Title:
BATTERY PACK
Document Type and Number:
Japanese Patent JP2022008536
Kind Code:
A
Abstract:
To provide a battery pack that can accurately detect the state of a battery.SOLUTION: A battery pack includes a battery and a sensor that detects the status of the battery, the sensor includes an insulation layer, and a resistor including a plurality of first resistance portions that are juxtaposed on one side of the insulating layer with the longitudinal direction facing the first direction and are not electrically connected to each other, and a plurality of second resistance portions that are juxtaposed on the other side of the insulating layer with the longitudinal direction facing a second direction intersecting the first direction and are not electrically connected to each other, and the first resistance portion and the second resistance portion are formed of a Cr mixed film containing α-Cr as a main component, and the state of the battery is detected as a change in a resistance value of the resistor.SELECTED DRAWING: Figure 10
