Using compressed air and highly sensitive pressure sensors, it detects leaks in the battery housing reliably and reproducibly – a professional test device in workshop quality for independent workshops, battery service centres and commercial test facilities.\u003c\/p\u003e\u003cul\u003e\u003cli\u003e✔ Test pressure 0–30 kPa with 1 Pa sensor resolution\u003c\/li\u003e\u003cli\u003e✔ Measuring accuracy ±5 Pa\u003c\/li\u003e\u003cli\u003e✔ Non-destructive testing with dry compressed air\u003c\/li\u003e\u003cli\u003e✔ Automatic test sequence in four phases\u003c\/li\u003e\u003cli\u003e✔ Automatic documentation of test results\u003c\/li\u003e\u003cli\u003e✔ Purchase on account available (Klarna or PayPal)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eHow the leak test works\u003c\/h3\u003e\u003cp\u003eThe EVC303 introduces a low test pressure (0–30 kPa) into the battery housing using dry compressed air. A pressure sensor with a resolution of 1 Pa measures the pressure change over time: if the housing is sealed, the pressure remains stable – if it drops below a defined threshold, the system detects a leak. The test sequence comprises four phases:\u003c\/p\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eFilling phase:\u003c\/strong\u003e building up the test pressure in the battery housing\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eStabilisation phase:\u003c\/strong\u003e pressure equalisation to compensate for material expansion\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eTest phase:\u003c\/strong\u003e monitoring the pressure drop to detect leaks\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eVenting phase:\u003c\/strong\u003e releasing the pressure and resetting the system\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eWhy battery pack tightness matters\u003c\/h3\u003e\u003cp\u003eA leaking battery pack can let in moisture, dust or gases – with the risk of short circuits, corrosion or fire. The EVC303 checks tightness before installation or after a repair, for example after a cell replacement or drying. As the test is non-destructive, the battery pack remains undamaged; this saves material and time compared with water or helium tests.\u003c\/p\u003e\u003ch3\u003eAreas of application\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eService and repair: leak testing after opening a high-voltage battery pack\u003c\/li\u003e\u003cli\u003eQuality inspection: checking battery module housings and seals\u003c\/li\u003e\u003cli\u003eEnd-of-line testing: testing every pack before vehicle assembly\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eOperating requirements\u003c\/h3\u003e\u003cp\u003eOperation requires a supply of dry compressed air (0.1–1.0 MPa) and a mains connection.
