Abstract
Official abstract text for this publication.
Energy storage arrangement with a rechargeable energy storage device, wherein the energy storage device includes a plurality of lithium-based storage elements. The energy storage device is composed of three lithium-based storage elements and one lithium titanate-based storage element, or four lithium-titanate-based storage elements and one lithium-based storage element, or three lithium-based storage elements and two nickel metal hydride-based storage elements.
First claim
Opening claim text (preview).
What is claimed is: 1. An energy storage arrangement comprising a rechargeable energy storage device having a plurality of lithium-based storage elements selected from one of the following configurations each including storage elements of different types: 3 storage elements based on lithium and 1 storage element based on lithium titanate, which are composed of different materials and thereby are the storage elements of different types, or 4 storage elements based on lithium titanate and 1 storage element based on lithium, which are composed of different materials and thereby are the storage elements of different types, or 3 storage elements based on lithium and 2 storage elements based on a nickel metal hydride, which are composed of different materials and thereby are the storage elements of different types. 2. The energy storage arrangement of claim 1 , wherein the plurality of storage elements are connected in series. 3. The energy storage arrangement of claim 1 , further comprising an electrical switching device connected upstream of the energy storage device. 4. The energy storage arrangement of claim 3 , wherein the electrical switching device is a safety switch configured to provide overload protection, undervoltage protection and temperature protection. 5. The energy storage arrangement of claim 1 , wherein the energy storage arrangement forms part of an onboard electrical system of a motor vehicle, wherein the onboard electrical system comprises at least one generator and at least one load consuming electrical power and disconnectable from the onboard electrical system. 6. The energy storage arrangement of claim 5 , wherein the at least one generator charges the energy storage device. 7. A motor vehicle, comprising at least one energy storage arrangement with a rechargeable energy storage device having a plurality of lithium-based storage elements selected from one of the following configurations each including storage elements of different types: 3 storage elements based on lithium and 1 storage element based on lithium titanate, which are composed of different materials and thereby are the storage elements of different types or 4 storage elements based on lithium titanate and 1 storage element based on lithium, which are composed of different materials and thereby are the storage elements of different types, or 3 storage elements based on lithium and 2 storage elements based on a nickel metal hydride, which are composed of different materials and thereby are the storage elements of different types. 8. The motor vehicle of claim 7 , wherein the energy storage arrangement forms part of an onboard electrical system of the motor vehicle, wherein the onboard electrical system comprises at least one generator and at least one load consuming electrical power and disconnectable from the onboard electrical system. 9. The motor vehicle of claim 8 , wherein the at least one generator charges the energy storage device. 10. An energy storage arrangement comprising a rechargeable energy storage device having a plurality of lithium-based storage elements selected from one of the following configurations each including storage elements of different types: 3 storage elements based on lithium and 1 storage element based on lithium titanate, which are composed of different materials and thus are the storage elements of different types, or 4 storage elements based on lithium titanate and 1 storage element based on lithium, which are composed of different materials and thus are the storage elements of different types, or 3 storage elements based on lithium and 2 storage elements based on a nickel metal hydride, which are composed of different materials and thus are the storage elements of different types, wherein the plurality of storage elements are connected in series; and an electrical switching device connected upstream of the energy storage device, wherein the electrical switching device is a safety switch configured to provide overload protection, undervoltage protection and temperature protection. 11. A motor vehicle, comprising at least one energy storage arrangement with a rechargeable storage device having a plurality of lithium-based storage elements selected from one of the following configurations each including storage elements of different types: 3 storage elements based on lithium and 1 storage element based on lithium titanate, which are composed of different materials and thus are the storage elements of different types, or 4 storage elements based on lithium titanate and 1 storage element based on lithium, which are composed of different materials and thus are the storage elements of different types, or 3 storage elements based on lithium and 2 storage elements based on a nickel metal hydride, which are composed of different materials and thus are the storage elements of different types, wherein the plurality of storage elements are connected in series; and an electrical switching device connected upstream of the energy storage device, wherein the electrical switching device is a safety switch configured to provide overload protection, undervoltage protection and temperature protection.
