Abstract

一种电动工具，包括壳体，收容于壳体内的马达(14)；电池包安装部(111)，可拆卸的安装至少两个电池包；主开关(12)根据用户操作而处于断开状态或闭合状态，主开关(12)处于闭合状态的情况下，电池包可以向马达(14)供电，在主开关(12)处于断开状态的情况下，电池包停止向马达(14)供电；控制组件(13)，检测主开关(12)所处的状态，在主开关(12)处于断开状态的情况下，控制组件(13)控制所述至少两个电池包中高压电池包的电能向低压电池包转移。还提供了一种电动工具供电方法。该电动工具能够在主开关断开时控制切换开关切换，使得多个电池包并联相互充电，实现多个电池包的电力均衡，从而延长总体工作时间，提高供电效率。
