発明の名称 (英語) BATTERY SYSTEM AND CHARGE/DISCHARGE MEASURING APPARATUS コモンズ
発明の概要(英語)

The present invention provides a charge/discharge measuring apparatus, which is capable of performing suitable charge/discharge management by accurately measuring a capacitance change of a secondary battery at the time of charging and discharging the secondary battery. This charge/discharge measuring apparatus is configured such that a current from a secondary battery can be switched to flow in a first connecting circuit, which connects in series the secondary battery, a load resistor, and a conductor film, or a second connecting circuit, which connects in series the secondary battery, a charger, and the conductor film. Furthermore the charge/discharge measuring apparatus has a voltage detecting means, which is disposed parallel to the conductor film, has a magnetic film connected in parallel to the connection to the load resistor and the charger from the secondary battery, and detects a voltage change in the magnetic film.
