PROBLEM TO BE SOLVED: To provide an auxiliary power unit, an antitheft device and a power supply method, capable of controlling charging according to a voltage change when power generated by the driving of a motorcycle is used.SOLUTION: An auxiliary power unit 100 attached to a motorcycle and enabling stable power supply includes: a charge determination unit 141 for determining whether or not to charge, according to the voltage of a main power; and a charger circuit 110 for charging from the main power to an auxiliary battery, according to the determination in principle. Preferably, the auxiliary power unit 100 further includes a stop determination unit 142 for determining the stop of charge according to the voltage of the auxiliary battery currently in charge. When the stop of charge is determined, the charger circuit 110 stops charging irrespective of the determination of the charge determination unit 141.

    【課題】オートバイの運転による発電を利用した場合に電圧の変化に応じて充電を制御できる補助電源ユニット、盗難防止装置および電力供給方法を提供する。【解決手段】オートバイに取り付けられ、安定した電力供給を可能にする補助電源ユニット100であって、主電源の電圧に応じて充電するか否かを判定する充電判定部141と、原則として判定に従い、主電源から補助バッテリへの充電を行なう充電回路110と、を備える。また、充電中の補助バッテリの電圧に応じて充電停止を判定する停止判定部142を更に備えることが好ましい。充電回路110は、充電停止を判定されたときには、充電判定部141の判定にかかわらず充電を停止する。【選択図】図1
