ELECTRIC POWER VOLTAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power storage device for achieving both stabilization of a voltage to a load and reduction in heat generation. SOLUTION: The power storage device includes: a main power supply terminal 17 electrically connected to a main power supply 13; a load terminal 19 electrically connected to the load 15; a relay 23 electrically connected between the main power supply terminal 17 and the load terminal 19 and constantly closed at normal time; and a power storage part 47 electrically connected to the load terminal 19 via an electronic switch 37 which is turned on for a period during which at least the relay 23 is generating chattering.
