BATTERY PACK AIRTIGHTNESS TESTER
BATTERY PACK AIRTIGHTNESS TESTER
After opening the HV battery housing for repair purposes, a leak test must be carried out after closing the HV battery housing. The cavity between the HV battery housing and the HV battery pack is pressurised with compressed air while a sensitive sensor detects pressure changes to assess the integrity of the seal. The system provides a real-time pressure curve, warnings of anomalies or faults and visual tracking of the test phases, including pressure build-up, stabilisation, leakage and venting. The system also displays the actual pressure and leakage changes in real time.
To test the tightness, the pressure build-up and pressure drop are determined by a determined by a sensor system
WARNINGS FOR TEST ABNORMALITIES OR ERRORS
DISPLAY OF THE PRESSURE CURVE IN REAL TIME FOR MONITORING
REAL-TIME DISPLAY OF PRESSURE AND LEAKAGE FLUCTUATIONS
Highly sensitive sensor
The accuracy and stability of the test is improved by the revised pressure sensor technology.
Visualisation of the process
The time required for each phase of the examination procedure can be displayed.
Work step
After the repair, the high-voltage battery is sealed and a leak test is carried out.
Parameter monitoring
The time required for each phase of the examination procedure can be displayed.
Personalised settings
Parameters such as volume, pressure, duration of each phase and leakage limit value can be defined in advance.
Intelligent warning
The device emits an audible and visual alarm if the values are abnormal or if the test is not passed.
