Abstract

A handheld tool battery device includes: a communication unit; at least one cell unit for storing energy; and at least one induction charging unit for charging and/or discharging the at least one cell unit. The communication unit transmits design-specific parameters to a charging device during a charging process.

Claims

1. A handheld tool battery device, comprising:

a communication unit;

at least one cell unit for storing energy; and

at least one induction charging unit configured to provide at least one of charging and discharging of the at least one cell unit;

wherein the communication unit transmits design-specific parameters to an external charging device during a charging process.

2. The handheld tool battery device as recited in claim 1, wherein the communication unit transmits a battery quality factor to the external charging device during a charging process.

3. The handheld tool battery device as recited in claim 2, further comprising:

a memory unit providing nonvolatile storage of the design-specific parameters.

4. The handheld tool battery device as recited in claim 2, wherein the communication unit additionally transmits to the charging device at least one characteristics variable of a maximum current of the cell unit during a charging process.

5. The handheld tool battery device as recited in claim 2, wherein the communication unit additionally transmits to the charging device at least one characteristics variable of a temperature of the cell unit during a charging process.

6. The handheld tool battery device as recited in claim 2, wherein the communication unit additionally transmits to the charging device at least one characteristics variable of a voltage of the cell unit during a charging process.

7. The handheld tool battery device as recited in claim 4, further comprising:

a registering unit for registering the at least one characteristics variable of the maximum current of the cell unit, wherein the registering unit has at least one sensor unit.

8. A system comprising:

a charging device; and

a handheld tool battery device including;

a communication unit;

at least one cell unit for storing energy; and

at least one induction charging unit configured to provide at least one of charging and discharging of the at least one cell unit;

wherein the communication unit transmits design-specific parameters to the charging device during a charging process, the communication unit transmitting a battery quality factor to the charging device during a charging process.
