Leak test on vehicle batteries with the workshop battery tester WBT01

  • Description

  • Battery testing with the workshop battery tester WBT01


    The WBT01 workshop battery test system is used to detect or localise leaks in vehicle drive batteries. 

    The device is currently available in three versions:

    - for overpressure type WBT01-AF

    - for vacuum type WBT01-BF

    - combined for positive/negative pressure of type WBT01-ABF


    Variant WBT01-BF:

    The test device has a connection to a vacuum pump (test pressure) and a connection to a test gas or overpressure supply. Furthermore, there is a plug-in coupling (SWAGELOK) on the front panel for connection to the test part.

    Variant WBT01-AF:

    The test device has a connection to an overpressure supply or a compressor (test pressure). Furthermore, there is a plug-in coupling (SWAGELOK) on the front panel for connection to the test part.

    Variant WBT01-ABF:

    The test device has one connection each to an overpressure supply or a compressor (test pressure) and to a vacuum pump. Furthermore, there is a plug-in coupling (SWAGELOK) on the front panel for connection to the test part. The selection for testing by means of overpressure or underpressure is made with the corresponding test programme parameters.


    The entire operation is carried out via the front panel. For this purpose, the unit has an LC display and various operating keys.


    The system can be used to detect leaks in the test object by means of negative or positive pressure. In addition, it is possible to use the flood function to apply tracer gas to the test object and search for leaks with the H2 sniffer APT-H2D.


    Implementation of the test procedure:

    After connecting the vacuum pump or compressor and the optional test gas supply, only the test part has to be connected to the front connection by means of a SWAGELOK coupling. The test is triggered by pressing the START key. The entire test sequence is controlled by freely programmable parameters. These parameters are stored fail-safe in the device.

    After the start, the test volume is first brought to the nominal test pressure. The vacuum pump or compressor is switched on by the test device for this purpose. The filling process can take some time depending on the volume size. To accelerate this process, the so-called shock filling method is used. Here the internal pressure regulator is set to the maximum possible filling pressure. If the lower tolerance limit of the test pressure in the test volume is reached, the test device switches over to the actual test pressure.

    After a further adjustment phase and a rest phase, any leakage is then measured and evaluated with a mass flow sensor in [Nccm/min].

    If the result was within the tolerances, the green lamp lights up. Otherwise, the red lamp indicates that the test was not OK.
