Abstract
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.
Claims11
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.
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.
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.
