Abstract
The present invention relates to a device (1) for detecting leaks for a motor vehicle battery pack, said device (1) comprising:—a pneumatic circuit (100) comprising a plurality of valves (V1, V2, V3) and a pressure sensor (106);—at least one connector (7) allowing to connect said pneumatic circuit (100) to at least one element of the battery pack; said device (1) being configured to carry out at least one procedure for detecting leaks on at least one element of the battery pack via said pneumatic circuit (100) and said connector (7).
Claims10
Device (1) for detecting leaks for a motor vehicle battery pack, said device comprising:
- a pneumatic circuit (100) comprising a plurality of valves (V1, V2, V3), a pressure sensor (104) and a pump (102);
- at least one connector (7) allowing to connect said pneumatic circuit (100) to at least one element of the battery pack;
- said pneumatic circuit (100) being configured to operate at least one procedure for detecting leaks under pressure and/or under vacuum on at least one element of said battery pack.
Device (1) according to any one of the preceding claims, characterised in that the device (1) comprises a man-machine interface (5).
Device (1) according to the preceding claim, characterised in that said device (1) is configured to have an inclination with respect to the surface on which the device is placed so that the man-machine interface (5) is oriented upwards.
Device (1) according to the preceding claim, characterised in that the angle of inclination is between 10 and 30 degrees.
Device (1) according to any one of the preceding claims, characterised in that said device (1) comprises at least one magnetised support foot (31).
Device (1) according to any one of the preceding claims, characterised in that said device (1) comprises at least one winding support (33).
Device (1) according to any one of the preceding claims, characterised in that said pneumatic circuit (100) comprises two one-way valves (V1 and V2), as well as a two-way valve (V3).
Device (1) according to any one of the preceding claims, characterised in that the pneumatic circuit (100) comprises at least one flow limiter.
Device (1) according to any one of the preceding claims, characterised in that it is configured to measure and take into account the value of the back pressure during a procedure for detecting leaks in at least one element of said battery pack.
