Abstract
A battery case leak testing device includes a housing having a testing port. A pump is in fluid communication with the testing port and is configured to generate a prescribed pressure at the testing port. A pressure sensor is in fluid communication with the testing port to measure fluid pressure at the testing port. A controller is in operative communication with the pump and the pressure sensor, and is configured to facilitate operation of the pump in a first mode and a second mode. In the first mode, the pump operates to generate a first prescribed pressure at the testing port. In the second mode, the pump operates to generate a second prescribed pressure at the testing port. The controller transitions the pump from the first mode to the second mode when the pressure sensor measures a prescribed pressure characteristic when the pump is operating in the first mode.
