    摘要： Dans le domaine des véhicules à assistance électrique, VAE, un procédé de gestion de l'alimentation électrique d'un VAE (10) doté d'au moins deux batteries (40, 41, 42), comprend de multiples bascules (600, 615) entre un premier mode de charge d'une première batterie (41) et d'alimentation d'un ou plusieurs moteurs électriques d'entrainement (32) par au moins une deuxième batterie (42) et un deuxième mode de charge de la deuxième batterie (42) et d'alimentation du ou des moteurs électriques (32) par au moins la première batterie (41). Les bascules sont fonction des états de charge respectifs des deux ou plus batteries (SoC1, SoC2). Un seuil de bascule vers le mode de charge d'une dite batterie est défini par un état de charge (SoC1, SoC2) de ladite batterie correspondant à une portion prédéfinie (N) de l'état de charge courant (SoC2, SoC1) de l'autre batterie en charge.

    摘要： A battery system (10) includes a first battery (12), a second battery (14), a first charging inlet (16), a charger (20), and an electric circuit (24). The electric circuit (24) is configured to be able to selectively establish one of a plurality of circuit structures including at least a first charging circuit structure and a first balancing circuit structure by selectively turning the plurality of switches (24a, 24b, 24c, 24d, 24e, 24f, 24g, 24h) on and off. In the first charging circuit structure, the first charging inlet (16) is electrically connected to a first end (21) of the charger (20) while the first battery (12) and the second battery (14) are electrically connected to a second end (22) of the charger (20). In the first balancing circuit structure, the first battery (12) is electrically connected to the first end (21) of the charger (20) while the second battery (14) is electrically connected to the second end (22) of the charger (20).

    摘要： A first switch (21) connects a series circuit (16) made up of a coil (15) and a third capacitor (13) between a high-voltage terminal (17a) and the intermediate-voltage terminal (17b). A second switch (22) connects the series circuit (16) between an intermediate-voltage terminal (17b) and a low-voltage terminal (17c). A third switch (23) connects the series circuit (16) with a power supply (90). A controller (24) switches a mode among the following three modes. In a first mode, the first switch (21) is closed, and the second switch (22) and the third switch (23) are open. In a second mode, the second switch (22) is closed, and the first switch (21) and the third switch (23) are open. In a third mode, the third switch (23) is closed, and the first switch (21) and the second switch (22) are open. The controller (24) controls the switches (21, 22, 23) such that the mode is repeated in order of the third mode, the first mode, the third mode, and the second mode.

    摘要： The HV junction device (JD) comprises a first battery terminal (B+) for connecting the first battery pack terminal (BP2+) of the second battery pack (BP2) and a second battery terminal (B-) for connecting the second battery pack terminal (BP1-) of the first battery pack (BP1). Furthermore, the HV junction device (JD) comprises a high voltage output with a first high voltage load terminal (HVL+) and a second high voltage load terminal (HVL-) for connecting a high voltage load group with one or more high voltage loads. The HV junction device (JD) also comprises a high voltage input with a first high voltage charge terminal (HVC+) and a second high voltage charge terminal (HVC-) for connecting an electric vehicle supply equipment. The HV junction device (JD) comprises a first contactor (C-DC+) and a second contactor (C-DC-) and the first battery terminal (B+) is connected to the first high voltage charge terminal (HVC+) via the first contactor (C-DC+) and the second battery terminal (B-) is connected to the second high voltage charge terminal (HVC-) via the second contactor (C-DC-). Furthermore, the HV junction device (JD) comprises a third contactor (C-M+) and a fourth contactor (C-M-) and the first battery terminal (B+) is connected to the first high voltage load terminal (HVL+) via the third contactor (C-M+) and the second battery terminal (B-) is connected to the second high voltage load terminal (HVL-) via the fourth contactor (C-M-). The junction device (JD) comprises a fifth contactor (C-BP1) and a sixth contactor (C-BP2) and a node (N) connectable to the second battery pack terminal (BP2-) of the second battery pack (BP2) and the first battery pack terminal (BP1+) of the first battery (BP1) for providing a voltage level of the connection between the first battery pack (BP1) and the second battery pack (BP2). The node (N) is connected via the fifth contactor (C-BP1) to the first high voltage charge terminal (HVC+) and via the sixth contactor (C-BP2) to the second high voltage charge terminal (HVC-).
