The invention relates to a charging method and system for an electric power-assisted bicycle and the electric power-assisted bicycle. The method comprises the steps that two sets of batteries in the electric power-assisted bicycle are set as a master battery and a slave battery, a handshake message is sent to the batteries first when a charger charges, and the batteries reply the handshake message to the charger; after the charger receives a handshake message replied by the battery, the handshake message is stopped from being sent, a charging message is sent to the battery regularly, the battery is charged after receiving the charging message sent by the charger, and the charging modes comprise four types. The method comprises a main battery independent charging method, a main battery and slave battery charging method, a slave battery independent charging method, a slave battery first charging method and a main battery later access charging method. According to the invention, the problem of two-time charging of the charger is solved.

    本发明涉及一种用于电助力自行车的充电方法、系统和电助力自行车,其中,方法包括将电助力自行车中的两组电池设为主电池和从电池,充电器充电时先对电池发送握手报文,电池向充电器回复握手报文,充电器收到电池回复的握手报文后,停止发送握手报文,转为定时向电池发送充电报文,电池收到充电器发送的充电报文后则进行充电,其中,充电方式包括四种类型,分别为主电池单独充电方法、主电池和从电池均要进行充电方法、从电池单独充电方法、从电池先充电,主电池后接入进行充电方法。本发明解决了充电器一充二问题。
