Resumen de: WO2025131717A2
A power supply system includes an external power supply that directly connects to a battery pack of a cordless power tool. Power is supplied to the power tool via a connection between the power supply and the battery pack. Since the power supply is connected directly to the battery pack, the power can be used to charge the battery of the battery pack when the tool is in the "off" state and provide power to the tool motor when the tool is in the on state to extend tool runtime. If the power tool is drawing less power than the power supply can provide, the difference in power is used to charge the battery, and if the tool is drawing more power than the power supply can provide, then the battery supplements the needed extra power.
