Abstract

The invention discloses an apparatus for battery pack water immersion tests. The apparatus for the battery pack water immersion tests comprises a pressure input member, wherein the pressure input member is connected with a compression gas source; a pressure vessel, wherein the pressure vessel is filled with liquid and used for placing a battery pack, and the pressure input member inputs compressed gas in the pressure vessel; a fluid pressure detection apparatus, wherein the fluid pressure detection apparatus detects the fluid pressure; and a controller, wherein the controller is connected with the pressure input member, the controller and the fluid pressure detection apparatus are connected, according to the detection value of the fluid pressure detection apparatus, the pressure of the compressed gas input by the pressure input member into the pressure vessel is controlled, so that the pressure with different immersion depths can be simulated through pressure control, the required pressure can be realized by adjusting the gas pressure, the operation is simple, the water depth simulation scope is wide, and the apparatus for basic construction requirement is low, enables closed-loop control through absolute pressure, and cannot be influenced by altitude height and extraneous environment, and can reduce the test cost.
