A self-running carrying system adopting an electric double-layer capacitor and a secondary battery as power supply, does not waste power when the system restarts after holidays and the like, has a long life and high practicability, and is capable of preventing weight and cost from increasing. The system comprises: a DC-DC converter (8), connected between the capacitor (7) and a drive control device (13); a lead-acid battery charger (9), configured to charge a lead-acid battery (10), wherein an output end of the charger is connected with an output end of the DC-DC converter (8) between the capacitor (7) and the drive control device (13); and a control circuit (12), configured to switch off a switch (11) when an output voltage (Vi) of the capacitor (7) is more than an output voltage (Vo) of the DC-DC converter (8), and to switch on the switch (11) when the output voltage (Vi) of the capacitor (7) is less than the output voltage (Vo) of the DC-DC converter (8).
Description
technical field [0001] The present invention relates to a self-propelled conveyance system which includes an electric double layer capacitor and a secondary battery in a self-propelled conveyance which moves along a predetermined path to convey a conveyance, and drives the self-propelled conveyance by using the electric power charged therein. Background technique [0002] There is a self-propelled conveying system using electric double layer capacitors as a power source. An automatic conveying vehicle is provided with a motor for driving driving wheels and its drive control device, and an electric double layer capacitor as a driving power supply. The charging power supply of the charging station at an appropriate location in the factory supplies the electric power charged to the electric double layer capacitor to the driving control device to drive the motor, thereby moving the automatic transport vehicle (see, for example, Patent Document 1). figure 1 and Fig. 4); Some self...
