Abstract

A battery arrangement is provided that includes battery cells that are electrically connected to one another, wherein each of the battery cells includes individual electrochemical cells. Each of the battery cells is thermally insulated from the further battery cells of the plurality of battery cells. Each of the individual electrochemical cells includes a monitoring device. The monitoring device is configured to electrically disconnect the battery cell from the further battery cells if at least one measured value that is to be monitored by the monitoring device lies outside a predetermined value range.

First claim

1 . A battery arrangement, comprising:
a plurality of battery cells that are electrically connected to one another; wherein each of the battery cells comprises a plurality of individual electrochemical cells; wherein each of the battery cells is thermally insulated from further battery cells of the plurality of battery cells; wherein each of the individual electrochemical cells comprises a monitoring device; and wherein each monitoring device is configured to electrically disconnect the battery cell from the further battery cells if at least one measured value that is to be monitored by the monitoring device lies outside a predetermined value range.

2 . The battery arrangement as claimed in claim 1 , wherein the battery cells are spaced apart with respect to one another.

3 . The battery arrangement as claimed in claim 1 , wherein the monitoring device comprises an ascertaining unit that is configured to ascertain the measured value that is to be monitored and relates to the individual electrochemical cell.

4 . The battery arrangement as claimed in claim 1 , wherein the monitoring device comprises an evaluating device configured to receive the measured value that is ascertained by the ascertaining unit and determines whether the measured value lies outside the predetermined value range.

5 . The battery arrangement as claimed in claim 3 , wherein the ascertaining unit comprises at least one temperature sensor for ascertaining the temperature of the individual electrochemical cells.

6 . The battery arrangement as claimed in claim 5 , wherein the monitoring device is configured to electrically disconnect the battery cell from the further battery cells of the plurality of battery cells if the temperature of the individual electrochemical cell that is ascertained by the temperature sensor lies outside a predetermined temperature range.

7 . The battery arrangement as claimed in claim 6 , wherein the monitoring device is configured so as to electrically disconnect the battery cell from the further battery cells if the ascertained temperature of the individual electrochemical cell lies above a predetermined temperature value.

8 . The battery arrangement as claimed in claim 3 , wherein each of the battery cells comprises at least one further ascertaining unit that comprises a voltage sensor for ascertaining the voltage that prevails at the battery cell.

9 . The battery arrangement as claimed in claim 8 , wherein at least one further ascertaining unit comprises a current sensor for ascertaining the current that prevails at the battery cell.

10 . The battery arrangement as claimed in claim 9 , wherein the individual electrochemical cell is a lithium rechargeable battery.

11 . The battery arrangement as claimed in claim 10 , wherein the lithium rechargeable battery is a lithium sulphur rechargeable battery.

12 . A vehicle comprising at least one battery arrangement as claimed in claim 11 .

13 . The vehicle as claimed in claim 12 , wherein the plurality of battery cells of the at least one battery arrangement is arranged distributed spaced apart with respect to one another over the vehicle.

14 . The vehicle as claimed in claim 12 , wherein the vehicle is a flying apparatus.

15 . The vehicle as claimed in claim 14 , wherein the flying apparatus is an unmanned aircraft.

16 . The vehicle as claimed in claim 14 , wherein the flying apparatus is a high altitude platform or station, or wherein the flying apparatus is a pseudo-satellite.
