Summary: | A dual voltage electrical architecture for a vehicle, comprising a low-voltage network, a high-voltage network and a DC/DC converter for transferring power from the high-voltage network to the low-voltage network, the electrical architecture further comprising a lithium-ion battery, a first and second contactors connected respectively to a positive and a negative terminals of the lithium-ion battery, a pre-charge circuit consisting of a pre-charge contactor and a pre-charge resistor connected in series, wherein the pre-charge contactor and the pre-charge resistor are connected in parallel with the first contactor, a battery management unit for controlling the opening and closing of the contactors and a vehicle start device. The DC/DC converter comprises a first input terminal connected to the first contactor and to the pre-charge contactor and a second input terminal connected to the second contactor. The only power source of the architecture is the lithium-ion battery delivering power to the high-voltage network. |
