摘要:
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.
摘要:
A charging method for a battery pack with each of the at least two series-connected cells being supplied with an effective charging current (ICharge), in a charging cycle (1) over a charging period, and being supplied with a lower effective refresh current. (Irefresh), in an at least occasional subsequent refresh cycle (2) over a refresh charging cycle (6). The refresh cycle (2) follows after a period (K) in a number (M) of charging cycles (1).
摘要:
A mobile electric appliance is disclosed. The mobile electric appliance includes at least one battery bay for accommodating a battery with at least one voltage-generating cell and a battery-side charge status indicator, an electrical consumer, a power connector, as well as a charging device for charging the at least one battery. In addition, the mobile electric appliance includes means for detecting the charge status of the at least one battery and a device-side charge status indicator arranged on the mobile electric appliance. The battery may also include an interface, which is prepared to relay the charge status determined to an external processing unit.
摘要:
A charging station (1) for a rechargeable battery (5) that can be electrically and physically connected to the rechargeable battery (5). The charging station (1) has charger electronics (2) in a charger housing (3) and an electrical and physical contact interface (4) for the battery (5). An air blower (6) producing an air current (L) through two air vents (7a, 7b) is arranged in the charger housing (3). The air vent (7a) of the physical contact interface (4) is spatially associated with the battery (5) and the charger electronics (2) is arranged in the air current (L) to transfer heat. In the cooling process, in a first stage, an air volume (V) at cooling temperature CT is moved past the battery to transfer heat into and onto the battery and, in a second stage, the air volume (V) at an intermediate temperature IT>CT permeates the charger housing (2) containing the charging electronics (2.).

摘要:
A battery pack (2) for an associated hand-held electric machine tool (1) and for an associated charging device (13) including an analog temperature sensor (3) with a negative temperature coefficient and a temperature measuring interface (4) accessible from the outside. Battery protection electronics (5) arranged in the hand-held electric machine tool (1) and in the charging device (13), which have a battery protection logic (6) and a power switch (8) that is arranged in the circuit path (7) of the battery pack (2) can be influenced. The battery pack (2) is provided with an emergency protection circuit (10), which is connected in parallel with the analog temperature sensor (3) and which, in emergency situations, can actively reduce the total resistance (R) measurable from the outside via the temperature measuring interface (4).
