A method for monitoring a first battery in a device, in particular in a motor vehicle, a first magnetometer measuring a magnetic flux density in the battery and/or adjacent to the battery, a second magnetometer measuring a magnetic flux density remotely from the first battery in the device, and in a period, in which no power supply or power withdrawal is provided to or from the first battery, a measurement of the first and the second magnetometer being carried out, and an evaluation unit, for the case in which the magnetic flux density measured by the first magnetometer exceeds a background magnetic flux density measured with the aid of the second magnetometer beyond a predetermined amount, determining and outputting an error status of the first battery.

Method for monitoring a battery, evaluation device, and measuring system

The invention relates to a battery module, in particular for a motor vehicle, which includes a housing, at least one battery disposed in the housing, at least one inlet opening for introducing a tempering fluid into the housing, at least one outlet opening for discharging the tempering fluid from the housing, and at least one monitoring device for detecting a state of the at least one battery. According to the invention, the at least one inlet opening and the at least one outlet opening can be sealed by at least one closure element in the event of a disruption condition of the at least one battery, so that materials exiting the at least one battery, in particular gases, during the disruption state can not escape from the battery module.

Battery module

An electrochemical energy store, including at least one electrochemical cell as well as at least one latent heat storage unit, which includes at least one phase change material. The at least one electrochemical cell is a lithium ion accumulator. The exemplary embodiments and/or exemplary methods of the present invention also includes the use of the electrochemical energy store in an electric vehicle or a hybrid vehicle. Furthermore, the exemplary embodiments and/or exemplary methods of the present invention relates to a method for temperature regulation of an electrochemical energy store.

Electrochemical energy store

A gas sensor based on solid electrolyte is proposed for measuring a gas component in a gas mixture, having at least one sensitive region, which has a first means for producing a reaction gas from an additional gas component of the gas mixture. A second means is situated in the sensitive region of the gas sensor, using which the residual content of the reaction gas may be determined, after a reaction that takes place between the reaction gas and the gas component to be measured.

Gas sensor and method for measuring a gas component in a gas mixture

The apparatus ( ) for treating exhaust gas from an internal combustion engine includes a storing catalyzer for absorbing NO during lean operating conditions and a device for burning fuel ( ) in an exhaust gas stream ( ) to produce a reducing atmosphere in the exhaust gas for storing catalyst regeneration and an aerodynamic control device for controlling the burning of the fuel in the exhaust gas stream, so that combustion is clearly improved when the engine is operated under lean operating conditions and no carbon is formed.

Method and apparatus for processing exhaust gas from an internal combustion engine

In a method and device for selective catalytic NOx reduction in oxygen-containing exhaust gases using ammonia and a reduction catalyst, gaseous ammonia is made available by heating a solid storage medium in a container. The method and device are suitable for use in motor vehicles in particular.
