Zusammenfassung:	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.
