BATTERY CHECKER
First Claim
1. A battery checker comprising:
- a voltage application unit configured to apply an AC voltage to a battery to be measured;
a ripple voltage measurement unit configured to measure a ripple voltage contained in a terminal voltage of the battery; and
an electric power storage level detection unit configured to detect an electric power storage level of the battery by comparing the ripple voltage measured by the ripple voltage measurement unit with a set reference.

Abstract
A battery checker is provided with: voltage application unit configured to apply an AC voltage to a battery to be measured; ripple voltage measurement unit configured to measure a ripple voltage contained in a terminal voltage of the battery; and electric power storage level detection unit configured to detect an electric power storage level of the battery by comparing the measured ripple voltage with a set reference. The voltage application unit includes a transformer that transforms voltage for an alternating current of an AC power supply such as a commercial AC power supply, and an output circuit that applies, to the battery, an alternating current with transformed voltage.
