Abstract
The invention relates to a DC electrical power supply source including a protective housing and electrical energy storage devices disposed in the protective housing. The storage devices are connected electrically in series by way of interconnection elements. There is an acoustic sensor configured to measure ultrasounds and a filling medium disposed in the housing. The filling medium exhibits a homogeneous acoustic impedance and forms a continuous acoustic link between the interconnection elements and the acoustic sensor.

A DC electrical power supply source, comprising:
- a protective housing;
- electrical energy storage devices disposed in the protective housing, said storage devices being connected electrically in series by way of interconnection elements;
- an acoustic sensor disposed in the protective housing, said acoustic sensor configured to measure ultrasounds;
- and
- a filling medium disposed in the protective housing;
- wherein the filling medium exhibits a homogeneous acoustic impedance and forms a continuous acoustic link between said interconnection elements and the acoustic sensor;
- and
- wherein the protective housing is leaktight so as to isolate the acoustic sensor from exterior acoustic disturbances.
