## Abstract

A storage-battery inductive charging device, particularly a hand-held-tool storage-battery inductive charging device, for a motor vehicle, having at least one functional unit and at least one charging coil. The functional unit is intended at least to control a charging process of the charging coil as a function of at least one energy-availability characteristic.

## Claims

### Claim 1

A storage-battery inductive charging device, comprising:
at least one functional unit; and
at least one charging coil;
wherein the functional unit is configured to control a charging process of the charging coil as a function of at least one energy-availability characteristic.

### Claim 2 (depends on 1)

The storage-battery inductive charging device as recited in claim 1, wherein the storage battery inductive charging device is for a motor vehicle.

### Claim 3 (depends on 1)

The storage-battery inductive charging device as recited in claim 1, further comprising:
a communication interface which, in at least one operating state, receives the energy-availability characteristic.

### Claim 4 (depends on 1)

The storage-battery inductive charging device as recited in claim 1, further comprising:
a sensor which, in at least one operating state, ascertains the energy-availability characteristic.

### Claim 5 (depends on 1)

The storage-battery inductive charging device as recited in claim 1, wherein the functional unit is configured to start the charging process of the charging coil as a function of the energy-availability characteristic.

### Claim 6 (depends on 1)

The storage-battery inductive charging device as recited in claim 1, wherein the functional unit is configured to stop the charging process of the charging coil as a function of the energy-availability characteristic.

### Claim 7 (depends on 1)

The storage-battery inductive charging device as recited in claim 1, further comprising:
at least one further charging coil;
wherein the functional unit is configured to prioritize a charging process of at least one of the charging coils.

### Claim 8 (depends on 7)

The storage-battery inductive charging device as recited in claim 7, wherein the functional unit is configured to prioritize the charging process of at least one of the charging coils as a function of job information.

### Claim 9 (depends on 7)

The storage-battery inductive charging device as recited in claim 7, wherein the functional unit is configured to prioritize the charging process of at least one of the charging coils as a function of usage information.

### Claim 10 (depends on 7)

The storage-battery inductive charging device as recited in claim 7, wherein the functional unit in configured to prioritize the charging process of at least one of the charging coils as a function of operator-input information.

### Claim 11

A hand-held-tool storage-battery inductive charging system, comprising:
an energy distributor;
a first and a second storage-battery inductive charging device, each of the first and second storage-battery inductive charging devices including at least one functional unit, at least one charging coil, wherein the functional unit is configured to control a charging process of the charging coil as a function of at least one energy-availability characteristic;
wherein the energy distributor is configured to distribute a charge energy to the storage-battery inductive charging devices and to acquire the energy-availability characteristic.

### Claim 12

A method utilizing a storage-battery inductive charging device, having at least one functional unit, the method comprising:
controlling, by the functional unit, a charging process as a function of at least one energy-availability characteristic.
