Description

Technical Field

[0001] The utility model relates to the technical field of automobile battery packs, in particular to a shell of an intelligent collision sensor. Background Art

[0002] Intelligent Crash Sensor (ICS): An embedded intelligent sensor within a battery pack that records damage to the internal and external structures of the battery pack during a collision or mechanical impact, or detects strong vibrations caused by internal explosions. The ICS consists of a master sensor and slave sensors. The master sensor (MasterSensor) is an intelligent sensor ICS that communicates with the vehicle or battery pack management system. The slave sensor (SlaveSensor) records signals and sends them to the master sensor during a collision or mechanical impact. The ICS can monitor the operating conditions of a vehicle (battery pack) in various states, including when stationary, in motion, and during collisions. When a vehicle (battery pack) is stationary, accidentally hit, or spontaneously combusts due to excessive temperature, it promptly provides relevant information to the onboard IBM, cutting off power and preventing further damage. When the battery pack is damaged while the vehicle (battery pack) is in normal operation, the frequency spectrum of the acceleration signal measured by its sensor will shift, which can be used to evaluate the mechanical condition of the battery pack. When a vehicle (battery pack) is operating on complex roads, the bottom of the battery pack is susceptible to impact from various foreign objects, causing varying degrees of damage and various forms of damage. Structural damage to the battery pack can cause short circuits between the positive and negative electrodes, leading to thermal runaway and spontaneous combustion. When a collision object dynamically impacts the battery pack at a certain speed, the battery pack is continuously squeezed and deformed internally and externally. When the vehicle is driving on bumpy roads, the system records the Z-axis acceleration signal. When the impact damage index is less than a threshold and the acceleration exceeds a preset threshold, it is counted as a severe bump. The shell of the current battery pack collision intelligent sensor has a complex structure, large size, and is inconvenient to install. It cannot meet the requirements of vibration and collision during the formation of the car and is easy to fall off. Utility Model Content
