Abstract: A power supply system for an electric vehicle includes a battery module, a first DC/DC converter, a second DC/DC converter, a first switch, a second switch and a third switch. The battery module has a negative electrode, a first positive electrode and a second positive electrode. The first DC/DC converter has an input terminal connected with the second positive electrode. The second DC/DC converter has an input terminal connected with the second positive electrode. The first switch is connected between the second positive electrode and the first DC/DC converter. The second switch is connected between the second positive electrode and the second DC/DC converter. The third switch is connected between the first positive electrode and an output terminal of the second DC/DC converter.
