Abstract

A hand-held power tool rechargeable battery is provided, including at least one rechargeable battery housing, at least one rechargeable battery cell and at least one inductive charging unit, which includes at least one inductive charging coil for charging the at least one rechargeable battery cell. It is provided that the rechargeable battery housing has at least one molded housing projection, which is delimited at least partially by an area of an inductive charging side of the rechargeable battery housing.

Claims (29)

1. A hand-held power tool rechargeable battery, comprising:

at least one rechargeable battery housing;

at least one rechargeable battery cell; and

at least one inductive charging unit that includes at least one inductive charging coil for charging the at least one rechargeable battery cell, wherein the rechargeable battery housing includes at least two molded housing projections that are delimited at least partially by an area of an inductive charging side of the rechargeable battery housing, wherein a first molded housing projection fastens in a direction parallel to a winding axis of the inductive charging coil, and a second molded housing projection fastens in at least one direction perpendicular to the winding axis of the inductive charging coil.

2. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the molded housing projection fastens to an inductive charging device.

3. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the rechargeable battery housing includes the first molded housing projection and the second molded housing projection.

4. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the inductive charging coil is situated at least partially within the first molded housing projection.

5. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the first molded housing projection includes at least one first fastening area and one second fastening area, the first and second fastening areas being situated on opposite sides of an inductive charging side of the rechargeable battery housing.

6. The hand-held power tool rechargeable battery as recited in claim 5 , wherein at least one of the first fastening area and the second fastening area is designed as a receiving shoulder.

7. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the second molded housing projection positions at least the inductive charging coil for a charging.

8. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the second molded housing projection includes at least one form-locking surface that extends at least essentially along a lateral surface.

9. The hand-held power tool rechargeable battery as recited in claim 1 , wherein the second molded housing projection includes at least one foreign body receiving recess that reduces an induction charging space.

10. A system, comprising:

an inductive charging device; and

a hand-held power tool rechargeable battery, including:

at least one rechargeable battery housing;

at least one rechargeable battery cell; and

at least one inductive charging unit that includes at least one inductive charging coil for charging the at least one rechargeable battery cell, wherein the rechargeable battery housing includes at least two molded housing projections that are delimited at least partially by an area of an inductive charging side of the rechargeable battery housing, wherein a first molded housing projection fastens in a direction parallel to a winding axis of the inductive charging coil, and a second molded housing projection fastens in at least one direction perpendicular to the winding axis of the inductive charging coil.

11. The system as recited in claim 10 , wherein the inductive charging device includes at least one fastening arrangement for fastening the molded housing projection of the hand-held power tool rechargeable battery at least one of in a force-locking manner and a form-locking manner.

12. The system as recited in claim 10 , wherein the inductive charging device includes at least one fastening arrangement for positioning the hand-held power tool rechargeable battery for the charging with the aid of the molded housing projection.

13. The system as recited in claim 12 , wherein the molded housing projection of the hand-held power tool rechargeable battery and the second fastening arrangement of the inductive charging device have basic shapes which differ from one another.

14. A hand-held power tool rechargeable battery, comprising:

at least one rechargeable battery housing;

at least one rechargeable battery cell; and

at least one inductive charging unit that includes at least one inductive charging coil for charging the at least one rechargeable battery cell, wherein the rechargeable battery housing includes at least one molded housing projection that is delimited at least partially by an area of an inductive charging side of the rechargeable battery housing,

wherein the molded housing projection is one of:

a first molded housing projection that fastens in a direction parallel to a winding axis of the inductive charging coil, and

a second molded housing projection that is fastens in at least one direction perpendicular to the winding axis of the inductive charging coil,

wherein the second molded housing projection includes at least one foreign body receiving recess that reduces an induction charging space.
