Batterie und Verfahren zu deren Betrieb

Die Erfindung betrifft eine Batterie (1) mit einem Batteriegehäuse (10) und zumindest einer Batteriezelle (11) und zumindest einem Sensor (2), welcher zumindest einen Dehnungssensor enthält oder daraus besteht, welcher dazu eingerichtet ist, eine Grössenänderung des Batteriegehäuses (10) und/oder der Batteriezelle (11) zu erfassen. Weiterhin betrifft die Erfindung ein Verfahren zur Steuerung oder Regelung der Ladung und/oder Entladung einer Batterie (1).

The invention relates to a battery (1) comprising a battery housing (10) and at least one battery cell (11) and at least one fiber optic sensor (2) which has at least one waveguide (20) with a core and a material surrounding said core. At least one fiber Bragg grating (21) is introduced in the core and is mechanically coupled to the battery housing (10) and/or to the battery cell (11) in order to detect a change in size of the battery housing (10) and/or of the battery cell (11). At least a second fiber Bragg grating (22) is introduced in the core and is mechanically decoupled from the battery housing (10) and the battery cell (11). The invention further relates to a method for the open loop or closed loop control of the charging and/or discharging of a battery, measurement values being acquired by at least one fiber optic sensor (2).
