The invention discloses a bidirectional charging method and a bidirectional charger for a storage battery, and relates to the technical field of motorcycle storage battery charging. The method comprises detecting the electric quantity of a motorcycle battery; judging whether the first USB port and the second USB port are connected with a power receiving device or a charging device; when the electric quantity of the storage battery of the motorcycle is larger than or equal to 10%, the motorcycle enters a charging mode, the one-way output module outputs power to the powered device through the first USB port, or the two-way charging module outputs power to the powered device through the second USB port; when the electric quantity of the motorcycle storage battery is smaller than 10% or the motorcycle storage battery breaks down, a reverse charging mode is entered, the first USB port stops working, and the charging equipment is allowed to supply power to the motorcycle storage battery through the second USB port and the bidirectional charging module. The invention has the beneficial effects that the motorcycle storage battery can be charged outwards when the electric quantity of the motorcycle storage battery is sufficient, and the improved charger can be used for directly charging the motorcycle storage battery by using an external power supply such as a charge pal when the electric quantity of the motorcycle storage battery is fed or a fault occurs, so that the motorcycle storage battery is prevented from being independently disassembled for special charging.

    本发明公开了一种双向充电方法及电瓶用双向充电器,涉及摩托车电瓶充电技术领域。本发明包括检测摩托车电瓶电量;判断第一USB口和第二USB口连接的是受电设备还是充电设备;当摩托车电瓶电量大于或者等于10%时,进入充电模式,单向输出模块通过第一USB口向受电设备输出电源,或者双向充电模块通过第二USB口向受电设备输出电源;当摩托车电瓶电量小于10%或者摩托车电瓶故障时,进入反充电模式,第一USB口被停止工作,充电设备被允许通过第二USB口和双向充电模块向摩托车电瓶供电。本发明的有益效果:既可以保证摩托车电瓶电量充足时向外充电,也可以在摩托车电瓶电量馈电或者故障时,利用改进后的充电器,直接利用外部电源如充电宝对摩托车电瓶充电,避免单独拆卸摩托车电瓶专门补电。
