  • the accumulators and / or the accumulator-operated tools may each have a coding element and the charging station associated with an accumulator and / or an accumulator-operated tool have a coding element that is complementary to the coding element, with loading of the accumulator or of the accumulator-operated tool preferably taking place only when the coding element cooperates with the corresponding coding element.
  • the means or the coding element and / or the complementary coding element can, for example, in a first, possibly leading, contacting, which makes a query regarding the appropriate charging voltage or the appropriate charging current, generated acoustic, visual and / or haptic (for example vibrate) signal.
  • This signal may originate from the accumulator or the accumulator-operated tool and / or the charging station.
  • a shutter member may also be effective to prevent further insertion and actual contact with respect to the charging voltage or the charging current with respect to the rechargeable battery or accumulator-operated tool. It is possible that the charging station reads out a tool-side and / or accumulator-side and preferably accumulator-specific RFID chip and the charging station Charging voltage is adjustable in dependence on the information stored in the RFID chip information in the charging station.
  • An evaluation unit required for testing whether an accumulator or an accumulator-operated tool is to be inserted into or connected to a non-matching charging device may be part of the charging device.
  • the evaluation unit can in particular make it possible to detect and evaluate measurable currents or voltages when inserting or first contacting the accumulator or accumulator-operated tool with the charging device.

So it is a form coding possible. In the simplest case, this can, for example, go from a smallest contact distance to a maximum contact distance.
  • An accumulator-operated tool 6, 7, 8, 9 with a larger contact distance can not be inserted into a charging station 2, 3, 4, 5 with a smaller contact distance.
  • An accumulator-operated tool 6, 7, 8, 9 with a smaller contact distance can then, for example, although possibly in a charging station 2, 3, 4, 5 are used with a larger contact distance, since this is not an electrical contact to the example. two required contacts can come, so no charging is possible.
  • the said means may consist in a detection of resistors and / or currents, which may preferably result in the course of insertion into a charging station 2, 3, 4, 5 (precontact).
  • the detected resistances and / or currents are evaluated by an evaluation unit as described above, wherein a charging station 2, 3, 4, 5 is deactivated in case of incorrect insertion of an accumulator-operated tool 6, 7, 8, 9.
  • the modular structure may mean that a charging station 2, 3, 4, 5 and / or a charging contact formed in the charging station 2, 3, 4, 5 or a unit of a plurality of charging contacts in a charging station 2, 3, 4, 5 in FIG easily exchangeable.
  • the interchangeability may require a tool operation, such as with a screwdriver. But it can also be given with respect to a latch, so that an appropriate replacement can be carried out without tools if necessary.
