Publication number: 20230123653Abstract: A method for controlling a battery-powered power supply. The method includes generating a first output from a first power supply within the battery-powered power supply. The first output is coupled to an output bus. The method further includes monitoring a voltage of the output bus, and determining, using a controller of the battery-powered power supply, whether the voltage of the output bus is less than a first predetermined level. The method further includes deactivating the first power supply in response to determining that the voltage of the output bus is below the first predetermined level, and generating a second output from a second power supply within the battery-powered power supply. The second output is configured to be coupled to the output bus. The second power supply has a higher output rating than the first power supply.Type: ApplicationFiled: December 21, 2022Publication date: April 20, 2023Inventor: Zachary G. Stanke

Publication number: 20230050963Abstract: A power regulation unit is provided for regulating power to or from a power tool battery pack. The power regulation unit includes power regulation circuitry and a controller. The power regulation circuitry is configured to regulate a received power. The controller is connected to the power regulation circuitry. The controller is configured to receive input power from one or more battery cells, regulate the input power by performing at least one of a voltage regulation and a current regulation, and output a regulated output power. For voltage regulation, the regulated output power includes a constant voltage regardless of an operating current of the power tool. For current regulation, the regulated output power includes a constant voltage up to a predetermined current threshold.Type: ApplicationFiled: August 12, 2022Publication date: February 16, 2023Inventor: Zachary G. Stanke
