Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of battery pack structure, specifically to a device for warning of battery pack impacts. Background Technology
[0002] As electric vehicles become more widespread, battery energy density is increasing. However, battery packs are high-risk components. Since battery packs are typically installed on the chassis of a car, if the chassis scrapes the bottom, the outer casing of the battery pack can be damaged, leading to internal battery compression and potential fire hazards.
[0003] However, existing battery pack casings cannot detect damage in a timely manner during actual use, which can easily lead to fires after an accident. Utility Model Content
[0004] 1. The technical problem to be solved by the utility model:
[0005] This utility model provides a battery pack impact warning device to solve the problem that damage to the battery pack casing cannot be detected in time during actual use, which can easily lead to fire accidents.
[0006] 2. Technical Solution:
[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a battery pack impact warning device, comprising a supporting lower base plate, a fixing clamp plate disposed on one side surface of the supporting lower base plate, a wiring terminal disposed on one side of the fixing clamp plate, an outer casing plate disposed on one side of the fixing clamp plate, a battery cell disposed between the supporting lower base plate and the outer casing plate, and a connecting base disposed on one side of the supporting lower base plate and the outer casing plate.
[0008] The outer casing includes an inner cell board, the surface of which is provided with recessed holes for installing cells. A pressure sensor is provided on the surface of the inner cell board, a top clamping plate is provided on the surface above the pressure sensor, a clamping strip is provided between the top clamping plate and the inner cell board, a fixing hole is provided on the surface of the pressure sensor, and a lower cell board is provided below the cells.
[0009] Furthermore, the top clamping plate, inner cell plate, lower cell plate, and supporting bottom plate are mounted on the vehicle surface via a connecting base.
[0010] Furthermore, the top clamping plate, inner cell plate, lower cell plate, and supporting bottom plate are all installed using screws, thereby installing the cell between the inner cell plate and the lower cell plate.
[0011] Furthermore, a slot is provided between the supporting lower base plate and the lower battery cell plate, and the pressure sensor is installed between the supporting lower base plate and the lower battery cell plate through the slot.
[0012] Furthermore, a rubber strip is provided at the lower end of the pressure sensor, and the rubber strip below the pressure sensor switches to send a signal to the battery pack host.
[0013] Furthermore, the battery pack host will feed the information back to the vehicle control panel, which will then provide feedback through visual cues.
[0014] 3. Beneficial effects:
[0015] This utility model is reasonably designed. When the battery pack is bumped and deformed during vehicle operation, the lower cell plate and the supporting base plate deform. At the same time, the pressure sensor and the switch rubber strip send deformation signals to the battery pack host BMS. The BMS feeds the information back to the vehicle control panel via the CAN communication signal. The vehicle control panel provides visual reminders to the driver, who can then arrange for the nearest repair to avoid causing the vehicle to catch fire or the battery pack to be scrapped.

This structure sends a signal to the battery pack host (BMS) via a rubber strip switch. The BMS then feeds back the information to the vehicle control panel via a CAN communication signal. The vehicle control panel provides visual feedback to the driver, allowing the driver to arrange for nearby repairs to prevent vehicle fires or battery pack failure.
