Abstract
A shock detection system for the battery pack of an electric vehicle, where the shock detection system uses at least one passive sensor, such as a knock sensor, for vibration detection. This sensor has large design freedom on the battery pack, either inside or outside, and is connected to the system for data treatment and data analysis. In addition to the knock sensor, the shock detection system also includes tuning forks located on the battery pack, where each tuning fork has a specific resonance frequency. During operation, when there is a shock or impact to the battery pack, each tuning fork resonates at a specific frequency, and the passive knock sensor detects these frequencies. The knock sensor then sends these frequency spectrums to the ECU of the electric vehicle, the ECU then determines the amplitude of the different frequencies and calculates the intensity and position of the impact using triangulation.
