The invention provides a sealing device and a sealing monitoring method, and the device comprises an annular first sealing module which is arranged between an upper cover of a CTB battery pack and a vehicle body door beam and is used for preventing liquid outside a whole vehicle from immersing into a member cabin in the vehicle. Meanwhile, the device is further provided with a first sealing monitoring module, and the first sealing monitoring module is connected with the signal processing module through a signal transmission module so as to monitor the sealing condition of the first sealing module in real time and judge the sealing performance of the whole vehicle; the matched sealing monitoring method comprises the steps that the types of liquid are determined based on the liquid invasion working condition, different kinds of liquid make contact with the first sealing module for calibration, and then the calibrated sealing device is used for continuously monitoring the sealing performance of the whole vehicle. The sealing performance of the CTB battery pack and the connecting position of the CTB battery pack and the vehicle body can be effectively monitored, and the safety and reliability of the vehicle are improved.

    本申请提供了一种密封装置及密封监测方法,装置包括:设置在CTB电池包上盖与车身门梁之间的环形第一密封模块,用于防止整车外部液体浸入车内成员舱。同时,装置还配备了第一密封监测模块,通过信号传输模块与信号处理模块相连,以实时监测第一密封模块的密封情况并判断整车密封性;配套的密封监测方法包括基于液体侵入工况确定液体种类,将不同液体分别接触第一密封模块进行标定,随后利用标定后的密封装置对整车密封性进行持续监测。本申请能够确保CTB电池包及其与车身连接处的密封性能得到有效监控,提升了车辆的安全性和可靠性。
