PROBLEM TO BE SOLVED: To provide a battery pack which is mounted on a power-assisted bicycle, enables non-contact charging to be performed only by altering an existing battery pack a little and also enables charging to be performed in accordance with a conventional method.SOLUTION: The battery pack includes: an accommodation case 31 accommodating a plurality of battery cells; a connector in electrical contact with a charger for charging the battery cells; and a power receiving coil 40 of a non-contact power supply transformer fixed on an outer wall surface or an inner wall surface of the accommodation case 31 for charging the battery cells with no contact. While being mounted on the power-assisted bicycle, the battery pack enables a power supply case 50 incorporating a power supply coil to be charged without contact while bringing the power supply case 50 into contact with the power receiving coil 40, and also to be charged in accordance with the conventional method, and standardization of non-contact charge can be easily implemented by using battery packs of respective bicycle manufacturers.

    【課題】電動アシスト自転車等に搭載される電池パックであって、既存のものに多少の改変を加えるだけで非接触充電が可能で、従来方式での充電も可能な電池パックを提供する。【解決手段】複数のバッテリセルを収容した収容ケース31と、バッテリセルを充電するために充電器に電気的に接触するコネクタと、バッテリセルを非接触充電するために収容ケース31の外壁面又は内壁面に固定された非接触給電トランスの受電コイル40とを備える。この電池パックは、電動アシスト自転車に装着したまま、給電コイルを内蔵する給電ケース50を受電コイル40に接触させて非接触充電することも、従来方式で充電することも可能であり、各自転車メーカーの電池パックを使って非接触充電への標準化が容易に実現できる。【選択図】図1
