Embodiment Construction

[0018] In the rechargeable battery according to the invention, which is shown schematically in the figures, a plurality of individual cells 1 are situated in a housing 2 next to one another in a plurality of rows, which cells each have a connection terminal at the top.

[0019] Cavities 4 are provided between the battery cells 1 and the housing cover 3 located above these battery cells. At the edge region of the cavity 4, preferably in a lateral projection of the housing 2, an infrared matrix sensor 5 is provided.

[0020] The inner side of the housing cover 3 , ie its surface oriented towards the cavity 4 , is provided with a reflective layer 6 which is reflective for infrared radiation. The detection range of the infrared matrix sensor 5 is oriented towards the reflection layer 6 and thus also indirectly towards the battery cells 1 .

[0021] The infrared rays 7 emitted on the side of the battery cell 1 facing the cavity 4 on the basis of the temperature of the battery cell...

Abstract

The invention relates to a storage battery, which, as required, is installed in a passenger transport vehicle as storage for the drive energy thereof, wherein the storage battery comprises a plurality of galvanic cells (1) and sensors for monitoring the states of the individual cells (1) for the purpose of generating warning signals concerning the failure of individual cells (1). One of the sensors is an infrared matrix sensor (5), wherein the detection range of the infrared matrix sensor (5) comprises an area on which surface sides of the plurality of individual cells (1) lie adjacent to one another.

Description

technical field [0001] The invention relates to an accumulator, which is intended to be installed in a vehicle for the transport of persons as a store for the drive energy of the vehicle. Background technique [0002] The possibility of "thermal runaway" cannot be completely ruled out in this type of battery. If the temperature limits associated with this are exceeded in the volume region of the battery, thermal runaway can occur - usually due to short circuits in the individual cells. This pushes the temperature further up as the elevated temperature leads to further reactions. Due to heat propagation, a larger volume area is affected by the increase in temperature and thus the amount of reactive species increases. [0003] In order to be able to prevent such events and to keep consequential losses as small as possible despite said events, the state of the battery is monitored by means of a number of sensors. According to one aspect of this monitoring, if an indication o...
