Title:
IMPACT DETECTION DEVICE AND POWER STORAGE PACK
Document Type and Number:
WIPO Patent Application WO/2021/060062
Kind Code:
A1
Abstract:
In this impact detection device (10) to be mounted on a power storage pack (1), an impact detection circuit detects an impact outside a permissible range by comparing three-axis detection values output from a three-axis acceleration sensor with threshold values respectively set to different values according to the mechanical characteristics of the power storage pack (1). For example, the power storage pack (1) comprises a winding-type cylindrical cell (C1), wherein a threshold value of an axis in a direction along a winding axis may be set to a value smaller in absolute value than threshold values of the other two axes.
