Abstract

A mobile energy store for outputting electrical energy. The mobile energy store has, in particular, a storage unit which may have a modular structure and may comprise storage modules, wherein the mobile energy store also has a number of rechargeable battery interfaces for outputting the electrical energy to rechargeable batteries and/or electrical devices comprising rechargeable batteries. A method for operating a mobile energy store, wherein the storage unit of the mobile energy store can be charged with electrical energy and the electrical energy is output from the storage unit to rechargeable batteries and/or electrical devices including rechargeable batteries with at least one rechargeable battery interface.

Claims (28)

1 . A mobile energy store for outputting electrical energy, the mobile energy store comprising:

a chassis for transporting the mobile energy store;

an energy storage unit connected to the chassis;

a control head connected to the energy storage unit, the control head including electronics for controlling an output of electrical energy from the energy storage unit; and

a plurality of rechargeable battery interfaces for outputting the electrical energy to rechargeable batteries or electrical devices including rechargeable batteries;

the chassis being connected directly to the energy storage unit via a first interface, and the energy storage unit being connected directly to the control head via a second interface.

2 . The mobile energy store as recited in claim 1 wherein the energy storage unit has a plurality of storage modules connected to one another by a storage module interface.

3 . The mobile energy store as recited in claim 1 wherein the mobile energy store includes at least one connection for a mains plug of an electrical device.

4 . The mobile energy store as recited in claim 1 wherein the mobile energy store, for the purpose of receiving electrical energy, includes a mains cable for connecting the mobile energy store to an energy network.

5 . The mobile energy store as recited in claim 1 wherein the energy storage unit is inductively chargeable.

6 . The mobile energy store as recited in claim 1 wherein the electronics communicate with the rechargeable battery interfaces in a wireless or wired fashion.

7 . The mobile energy store as recited in claim 1 wherein the interfaces are electrical or mechanical interfaces.

8 . The mobile energy store as recited in claim 1 wherein the control head includes a control panel connected to the electronics for communication in a wired or wireless fashion.

9 . The mobile energy store as recited in claim 1 wherein the control head includes a display device connected to the electronics for communication in a wired or wireless fashion.

10 . The mobile energy store as recited in claim 1 wherein the chassis includes a drive with a motor, wherein the motor obtains drive energy from the energy storage unit of the mobile energy store.

11 . The mobile energy store as recited in claim 1 wherein the chassis includes wheels connected to an axle.

12 . The mobile energy store as recited in claim 1 wherein the chassis includes castors.

13 . A method for operating a mobile energy store as recited in claim 1 , the method comprising the following steps:

a) providing the mobile energy store;

b) charging the energy storage unit of the mobile energy store; and

c) outputting electrical energy from the energy storage unit of the mobile energy store to the rechargeable batteries or the electrical devices via the at least one rechargeable battery interface.

14 . The method as recited in claim 13 wherein an amount of electrical energy to be output is settable via storage modules in the energy storage unit of the mobile energy store.

15 . The method as recited in claim 13 wherein the electrical energy is also output via a connection for a mains plug of an electrical device.

16 . The mobile energy store as recited in claim 1 wherein the first interface electrically and mechanically connects the energy storage unit and the chassis, the chassis further comprising wheels located below the energy storage unit.

17 . The mobile energy store as recited in claim 1 wherein the energy storage unit constitutes a modular storage unit composed of a plurality of storage modules one above the other.

18 . The mobile energy store as recited in claim 17 wherein the storage modules are connected to one another via third interfaces.

19 . The mobile energy store as recited in claim 18 further comprising brackets connecting the storage modules in addition to the third interfaces.

20 . The mobile energy store as recited in claim 17 wherein the control head is arranged above the energy storage unit.
