1. A driverless power supply system, comprising: a high-voltage battery box (1), a direct current converter (2), a main storage battery (3), a standby storage battery (4), a power domain controller (5) and an electrical load (6);
the direct current converter (2) is respectively connected with the high-voltage battery box (1) and the electrical load (6) through wires;
the main storage battery (3) is respectively connected with the direct current converter (2) and the electrical load (6) through wires;
the standby storage battery (4) is respectively connected with the direct current converter (2) and the electrical load (6) through wires; and
the power domain controller (5) is respectively connected with the direct current converter (2), the main storage battery (3) and the standby storage battery (4) through data wires;
wherein the system further comprises an electrical box (11);
the direct current converter (2), the main storage battery (3) and the standby storage battery (4) are respectively connected with a first end of the electrical box (11) through wires;
the power domain controller (5) and the electrical load (6) are respectively connected with a second end of the electrical box (11) through wires, and the power domain controller (5) is connected with a third end of the electrical box (11) through data wires;
the electrical box (11) is configured to, in response to any one of the direct current converter (2), the main storage battery (3) and the standby storage battery (4) failing to work, cutting off power supply to the electrical load having a non-safety function, and supplying power to the electrical load having a safety function.
