System and method for controlling vehicle electric power and vehicle comprising the system

A system for controlling an electric power supply, comprising:

• at least one dc-dc converter;
• a startup generator and a storage battery, configured to supply a first voltage via the at least one dc-dc converter, wherein the at least one dc-dc converter is configured to convert the first voltage into a second voltage;
• and
• a controller configured to:
• control at least one of the startup generator and the storage battery to supply power, via the at least one dc-dc converter, to a first device with the first voltage, and to supply power, via the at least one dc-dc converter, to a second device with the second voltage;
• detect a status of a motor;
• if the motor is detected to be off, control the at least one of the startup generator and the storage battery to stop supplying power, via the at least one dc-dc converter, to the first device;
• monitor an electric quantity of the storage battery;
• and
• if detecting that the electric quantity of the storage battery is less than a first predetermined electric quantity threshold and if detecting that the motor is off, initiate turning on the motor.

A vehicle, comprising:

• a motor;
• at least one dc-dc converter;
• a startup generator and a storage battery, configured to supply a first voltage via the at least one dc-dc converter, wherein the at least one dc-dc converter is also configured to convert the first voltage into a second voltage;
• and
• a controller configured to:
• control at least one of the startup generator and the storage battery to supply power, via the at least one dc-dc converter, to a first device with the first voltage, and to supply power, via the at least one dc-dc converter, to a second device with the second voltage;
• detect a status of a motor;
• if the motor is detected to be off, control the at least one of the startup generator and the storage battery to stop supplying power, via the at least one dc-dc converter, to the first device;
• monitor an electric quantity of the storage battery;
• and
• if detecting that the electric quantity of the storage battery is less than a first predetermined electric quantity threshold and if detecting that the motor is off, initiate turning on the motor.
