Abstract

The invention discloses a battery box leakage detection device and method, and relates to the technical field of new energy battery safety detection. The battery box body leakage detection device is used for detecting the damage degree of a battery box body, the battery box body is provided with a hollow interlayer, the hollow interlayer is filled with rare gas with preset pressure, and the battery box body leakage detection device comprises: a rare gas detector used for detecting the concentration of the rare gas in the battery box body; and a pressure sensor which is used for detecting the pressure of the rare gas in the hollow interlayer. According to the invention, the damage degree of the battery box body can be well detected, so that a driver and passengers can take corresponding measures according to different conditions, and the property and personal safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of new energy battery safety detection, in particular to a battery box leakage detection device and detection method. Background technique [0002] With the increase in the number of electric vehicles, new energy batteries have also been widely used, and lithium batteries are the most widely used among new energy batteries. Lithium batteries are used in the form of battery packs. The battery pack includes a battery box and a battery pack. The battery pack is packaged in the battery box. The battery box is installed on the electric vehicle. There is a risk of thermal runaway. [0003] The current power battery products only add protective plates on the bottom of the battery pack to enhance the strength of the battery pack or arrange devices such as temperature and humidity sensors in the battery pack to detect the airtightness of the battery pack, but none of the above methods can accurately determine the da...
