Title:
RELAY DRIVE CONTROLLER, CONTROL METHOD, AND CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP2023136163
Kind Code:
A
Abstract:
To provide a relay derive controller capable of driving a relay, while suppressing an increase in cost and scale (size and weight).SOLUTION: A relay derive controller for connecting a battery installed in a vehicle with an external power supply comprises a voltage conversion part for converting an output voltage into a drive voltage to be output to a control part by inputting the output voltage from the battery, and the control part for supplying the drive voltage input from the voltage conversion part to the relay. The control part controls the voltage conversion part so as to raise the drive voltage up to a first voltage value that is relay-drivable when driving the relay, and supplies the drive voltage to the relay when the drive voltage reaches the first voltage value.SELECTED DRAWING: Figure 1
