摘要:
Système de protection pour batterie d'automobile en cours de stockage capable de détecter une chute de tension (20) jusqu'à un niveau où la batterie a encore assez de puissance pour que le véhicule puisse démarrer. Si la tension détectée reste au niveau indiqué ou en deçà pendant un délai supérieur au temps normalement nécessaire pour faire démarrer le véhicule, la batterie (10) est déconnectée de la charge (14) et un signal d'hystérésis (34) interdit le rétablissement de cette connexion pendant que la tension de la batterie commence à remonter, cette dernière n'étant plus soumise à une charge. La charge est automatiquement reconnectée à la batterie par la mise en fonction du contact (18) pour redémarrer. Un circuit de remise à zéro fournit une petite tension (44) de test à la charge déconnectée et détecte toute chute de tension imputable à la mise en oeuvre du contact de démarrage. Cette chute de tension est détectée et entraîne le rétablissement de la connexion de la batterie aux charges par un contact principal (12).

Disclosed is a battery disconnect unit (BDU) that is good in assemblability and couplability because a middle cover accommodated in a lower case stably supports a relay terminal and a guide bar and a hood structure are applied to the middle cover. The BDU is disposed between a battery and an inverter to stably supply or break power of the battery to a power system of a vehicle. The BDU includes a lower case provided in a box shape with a top opened and a middle cover accommodated into and coupled to the lower case to press the relay terminal. A relay terminal hole into which a relay terminal is fitted is disposed on a bottom of the lower case, and an electric component is mounted on a top of the middle cover. A first fixing hook capable of being fastened to the lower case is provided in the middle cover.

The polarity reversal protection unit comprises a pyrotechnic separation unit, a detector unit, a trigger element, a first connection element that is electrically connected to at least one consumer connection and a second connection element that electrically connects a supply supporting structure to the first connection element. The pyrotechnic separation unit is located on at least one of the connection elements. The trigger element has a first connection to the detector unit, said connection being electrically insulated from the connection elements and a second connection to one of the connection elements in such a way that a current flux in the trigger element causes the firing of the pyrotechnic separation unit, causing the electrical separation of the first and second connection elements.

The invention relates to a battery current sensor for a motor vehicle, comprising a measuring sensor that is integrated into the battery current circuit and a measuring circuit assembly that is connected to the measuring sensor. At least parts of the measuring current assembly are located on a circuit carrier, which is electrically and mechanically connected in a fixed position to the measuring sensor by means of connecting elements, each of said connecting elements having a respective press-fit contact, which connects them to the circuit carrier and/or the measuring sensor.
an insulating support structure (3), two electrical connection terminals (4,5) fixed in spaced relation to this support structure (3), a guide stem (7) fixed orthogonally to the said structure (3) in a region intermediate between the terminals (4,5), a movable electrical connection bridge (8) displaceable along the stem (7) between a rest position and a working position in which it connects or respectively disconnects the terminals (4,5); a spring (14) tending to urge the connection bridge (8) towards its rest position, a control member (15) which can be operated manually to cause the connection bridge (8) to move from the rest position to the working position; a spring retaining device (20-24) for maintaining the control member (15) in the position in which it keeps the connection bridge (8) connected to the terminals (4,5); and a disengagement device (30-33) which can be operated to release the control member (15) from the associated retaining device (20-24) and allow the movable bridge (8) to be disconnected from the terminals (4,5) under the action of the spring (14).
