Abstract

In a power storage system, a first switch is connected between a first node and a second node. The first node is connected to a positive terminal of a power storage unit, and the second node is connected to a positive terminal of a load. A second switch is connected between a third node and a fourth node. The third node is connected to a negative terminal of the power storage unit, and the fourth node is connected to a negative terminal of the load. A first comparator circuit compares a first voltage based on a voltage between the first and fourth nodes with a first reference voltage. A second comparator circuit compares a second voltage based on a voltage between the second and third nodes with a second reference voltage.
