Abstract
A sensor for detecting liquids in apparatuses for storing energy, an apparatus for storing energy, a monitoring system for monitoring apparatuses for storing energy, and a method for monitoring apparatuses for storing energy are provided.
Claims17
A sensor (1) for selectively detecting liquids in apparatuses for storing energy, wherein the sensor (1) comprises at least one porous absorption layer (3) for absorbing liquids.
An apparatus (6) for storing energy, comprising at least one store for electric energy, which is arranged in the inside of a housing (7), and at least one sensor (1) according to at least one of the preceding claims, wherein the sensor (1) cooperates with the inside of the housing (7) for detecting liquids in the housing (7).
A monitoring system (1, 5, 6) for monitoring apparatuses for storing energy, comprising:
- an apparatus (6) for storing energy;
- and
- a signal evaluation and control device (5), which interact such that,
- when a sensor (1) detects selectively whether it is in contact with water or with an electrolyte,
- the signal evaluation and control device (5) isolates the apparatus (6) from a load of the apparatus (6) in order to avoid damage and/or produces a signal for changing the apparatus (6).
A method for monitoring apparatuses (6) for storing energy, comprising the steps
- at least intermittent monitoring, using a sensor (1) for determining whether there is water or an electrolyte in the housing of the apparatus,
- producing a detection signal by way of the sensor (1) as a function of a result of the monitoring,
- receiving and evaluating the detection signal produced by the sensor (1) using a signal evaluation and control device (5) and
- controlling the apparatus (6) for avoiding damage to the apparatus (6) and/or for the further operation of the apparatus (6) on the basis of the received and evaluated detection signal using the signal evaluation and control device (5).
