1. A battery module for a motor vehicle comprising a housing enclosing electrical energy storage cells, wherein
the battery module comprises a device for monitoring a characteristic of a fluid contained in the housing of the module in order to diagnose deterioration of at least one of the electrical energy storage cells enclosed in the housing of the module,
the device for monitoring comprises at least one detection element mounted on the housing of the module and configured to determine a presence of a gaseous pollution fluid escaping from at least one of the electrical energy storage cells different from the fluid contained in the housing of the module, and
the detection element comprises an electrical conductivity sensor for measuring a variation in electrical conductivity of the fluid contained in the housing of the module including the gaseous pollution fluid escaping from at least one of the electrical energy storage cells.
