NOVELTY - The battery compartment (1) comprises an outer casing (2) defining a chamber for receiving a battery, a disconnector, which includes a base provided with spaced-apart electrical contact units and is connected to a removable member provided with a cutoff bar, an internal partitioning for defining compartments, and holding tabs installed under a vehicle. The base of the disconnector is attached to the outer casing, and the removable member of the disconnector is accessible to exterior of the casing when the member is connected to the base.    USE - The battery compartment is useful for a vehicle such as an electric or hybrid vehicle.    ADVANTAGE - The battery compartment enhances reliability of the electric or hybrid vehicle.    DETAILED DESCRIPTION - The battery compartment (1) comprises an outer casing (2) defining a chamber for receiving a battery, a disconnector, which includes a base provided with spaced-apart electrical contact units and is connected to a removable member provided with a cutoff bar, an internal partitioning for defining compartments, and holding tabs installed under a vehicle. The base of the disconnector is attached to the outer casing, and the removable member of the disconnector is accessible to exterior of the casing when the member is connected to the base. One of the contact unit of the base is electrically connected to the first electrical terminals of the battery via a first electrical connection unit, and the other contact unit of the base is connected to the second electrical contact unit of the base intended for an external electrical connection of the battery. The disconnector is installed in an exterior hollow recess of the outer casing, where the recess tapping towards the base. The second electrical contact unit is connected to an electronic device (11). The battery comprises accumulator blocks (7) electrically mounted in series, where the blocks are disposed in the compartments. The outer casing comprises a box-shaped support, and a cover (4) covering the support.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic perspective view of a battery compartment.
