Abstract
In impact detection device to be mounted on power storage pack, an impact detection circuit compares detection values of three axes output from a three-axis accelerometer sensor with thresholds set to different values according to mechanical characteristics of power storage pack, and detects an impact outside an allowable range. For example, power storage pack includes wound cylindrical cells, and a threshold of an axis in a direction along a winding axis may be set to a value smaller in absolute value than thresholds of other two axes.
