Abstract

L'invention concerne un dispositif de commutation de séparation ou de liaison galvanique d'une borne de batterie au moins bipolaire, d'une borne d'onduleur au moins bipolaire et d'une borne de chargeur au moins bipolaire. Le dispositif de commutation comprend au moins une protection de batterie (BS1, BS2) comprenant respectivement un pôle de raccordement (B1, B2) de batterie et au moins une protection de chargeur (LS1, LS2) avec respectivement un pôle de raccordement (L1, L2) de chargeur. Une protection de batterie (BS1, BS2) pourvue d'une protection de chargeur (LS1, LS2) est branchée en série entre le pôle de raccordement de batterie (B1, B2) respectif et le pôle de raccordement de chargeur (L1, L2). Une prise médiane entre la protection de batterie (BS1, BS2) et la protection de chargeur (LS1, LS2) est reliée au pôle de raccordement d'onduleur (W1, W2) respectif.
