Electric Vehicle High-Voltage Battery Airtightness Testing Device EVT511

Country of origin: Germany, warranty period - 24 months

The EVT511 is a specialized high-voltage (HV) battery airtightness testing device for electric vehicles. After opening the HV battery housing for repair work, it is necessary to conduct an airtightness test before reinstalling the battery into the vehicle. The device pressurizes the cavity between the HV battery housing and the battery module with compressed air, while a highly sensitive sensor detects pressure changes to assess the integrity of the seal. The EVT511 provides real-time pressure fluctuation graphs, sends alerts for potential leaks, and allows visual monitoring of the testing process.

Features:

• Pressure change analysis: Tests airtightness by monitoring pressure increase and decrease.
• Automatic alerts: Visual and audible warnings for test errors or anomalies.
• Real-time monitoring: Accurate pressure curve display and detection of leakage fluctuations.
• High-sensitivity sensor: Latest sensor technology ensures improved accuracy and stability.
• Process visualization: Allows monitoring of each test phase (pressure increase, stabilization, leakage, venting).
• Parameter monitoring: Enables pre-setting of test phase durations, pressure parameters, and leakage limits.
• Smart warning system: Automatically notifies users of abnormal readings or failed tests.
