    Abstract: Method for charging an accumulator having an energy storage cell, a data interface and a wake-up circuit. A charging apparatus contains a data interface, a controller, a timer and a switch apparatus. The data interfaces are connected to one another via a communication line for differential communication between the accumulator and the charging apparatus. The method includes setting the timer to a predetermined period of time; setting the control electronics of the accumulator to a deactivation mode; sending at least one signal from the charging apparatus to the accumulator via the communication line after the predetermined period of time has elapsed; activating the wake-up circuit for activating control electronics by detecting a voltage value from the communication line, wherein the voltage value is consistent with either the dominant or recessive state of the communication line; setting the control electronics to an activation mode; and requesting or releasing a charging current from the charging apparatus by means of the accumulator.

    Abstract: Method for communication between a power tool and a rechargeable battery, wherein the rechargeable battery includes a controller unit having a first transceiver, and the power tool includes a control unit having a second transceiver. The method involves the method steps of emitting a first signal from the first to the second transceiver; emitting a second signal from the first to the second transceiver after a predetermined period of time has elapsed; shifting the power tool from a first operating state into a second operating state if the number of received signals in a predetermined period of time reaches a predetermined threshold value, and/or emitting a signal to the first transceiver in order to shift the rechargeable battery from a first operating state into a second operating state if the number of received signals in a predetermined period of time reaches a predetermined threshold value. System for performing the method for communication, including a power tool and rechargeable battery. Rechargeable battery for performing the method for communication. Power tool for performing the method for communication.
