Title
(EN) A BATTERY JUNCTION BOX AND A BATTERY PACK FOR A VEHICLE
(FR) BOÎTE DE RACCORDEMENT DE BATTERIE ET BLOC-BATTERIE POUR VÉHICULE
Abstract
(EN)
A battery junction box (100), comprising: a first input (101) connected to a first output (102) via a switch circuit (103), which switch circuit is configured to connect the first input to the first output upon receiving a control signal from a controller (104); the battery junction box further comprises a second input (109) connected to a second output (108), via a fuse (F1) and a main switch (SW0) arranged in series. The switch circuit (103) further comprises at least a first branch (105) with a semiconductor switch (S1-S3) between the first input and the first output, which semiconductor switch has a control line (106) connected to the controller; and the switch circuit further comprises a second branch (107) with a snubber circuit, which second branch is parallell with the first branch between the first input and the first output; and a flywheel diode (D1) with a first terminal connected to the first output, and a second terminal connected to the second output.

L'invention concerne une boîte de raccordement de batterie (100), comportant : une première entrée (101) connectée à une première sortie (102) par l'intermédiaire d'un circuit de commutation (103), le circuit de commutation étant conçu pour connecter la première entrée à la première sortie lors de la réception d'un signal de commande provenant d'un dispositif de commande (104) ; la boîte de raccordement de batterie comportant en outre une seconde entrée (109) connectée à une seconde sortie (108), par l'intermédiaire d'un fusible (F1) et d'un commutateur principal (SW0) agencés en série. Le circuit de commutation (103) comporte en outre au moins une première ramification (105) avec un commutateur à semi-conducteur (S1-S3) entre la première entrée et la première sortie, ledit commutateur à semi-conducteur ayant une ligne de commande (106) connectée au dispositif de commande ; et le circuit de commutation comporte en outre une seconde ramification (107) avec un circuit d'amortissement, la seconde ramification étant parallèle à la première ramification entre la première entrée et la première sortie ; et une diode à effet de volant (D1) avec une première borne connectée à la première sortie, et une seconde borne connectée à la seconde sortie.
