An impact damping device is contained between the housing and the battery interface device, wherein the impact damping device contains at least one damping element which is arranged in a longitudinal extent perpendicularly to a working axis of the power tool.

Abstract: A power tool, in particular a chipping hammer, containing a first and second side handle and a tool housing having an interface for releasably receiving and holding a first and second rechargeable battery, wherein a side-handle axis extending through the first and second side handles is arranged substantially perpendicularly to a working axis extending through the tool housing. The power tool contains a protective apparatus for protecting the first and second rechargeable batteries, the protective apparatus having an internal volume for at least partially receiving the first and second rechargeable batteries.

Abstract: Provided are a computer program product, system, and method for performing a failover between a first storage system and a second storage system. Data is synchronized between the first storage system and the second storage system. A failover is performed from the first storage system to the second storage system in response to a failover event at the first storage system while synchronizing the data. A determination is made that a first storage unit of the first storage system is inoperable and that that a second storage unit of the first storage system is operable in response to the failover event. In response to determining that the second storage unit is operable, a resynchronization is initiated to copy updates to a second storage unit of the second storage system mirroring the second storage unit of the first storage system to the second storage unit of the first storage system.

Abstract: The battery unit according to the invention for a handheld machine tool comprises a number of battery cells, with at least one of the battery cells being embodied as an isolation battery cell, and showing a fire protection jacket comprising an intumescent material. The fire protection jacket surrounds the isolation battery cell at least partially such that the isolation battery cell is surrounded by the fire protection jacket at a predetermined temperature such that the isolation battery cell is thermally insulated.

Abstract: A method to monitor the current of a handheld power tool (3) operated by a battery (2), by at least one counter (5), includes the following steps: measuring (S1) the electric current (I) drawn from the battery during the operation of the electric tool; incrementing (S2) a reading (Z, Z1, Z2) of the counter (5) by a certain increment (IN) whenever the measured current (I) is higher than a specified upper limit value (G1, G2) during a given counting interval; decrementing (S3) the reading of the counter by a certain decrement (DE) whenever the measured current is lower than the specified upper limit value during the given counting interval; and switching off (S4) the electric tool when the reading (Z, Z1, Z2) of the counter is higher than a specified limit value (T1, T2) for the counter.

Abstract: A control method for a system of a hand power tool and an accumulator battery is disclosed. The hand power tool is connectable to the accumulator battery via a current interface for supplying the hand power tool. The hand power tool features a data interface for communicating with the accumulator battery. Characterizing data of the hand power tool and/or data about an operating process of the hand power tool is transmitted to the accumulator battery via the interface.
