Title:
RELAY UNIT, HEATER CONTROL DEVICE, HEATER DEVICE, AND HEATER CONTROL METHOD
Document Type and Number:
Japanese Patent JP2018012442
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a relay unit, a heater control device, a heater device and a heater control method, which can suppress decrease in voltages of a storage battery when power supply is on, by controlling a heater having a pair of power supply terminals.SOLUTION: A switch device 21 has a relay 21a which can switch between an on-state where an electric path 51 is conducted and an off-state where the electric path 51 is blocked. Switch devices 22-25 have relays 22a-25a which can switch between an on-state where electric paths 52-55 are conducted and an off-state where the electric paths 52-55 are blocked, and resistances 22b-25b connected in series in the electric paths 52-55. When power supply is started from a storage battery 4 to a heater 3, the relays 22a-25a are turned on, then the relay 21a is turned on and then the relays 22a-25a are turned off.SELECTED DRAWING: Figure 1
