- DE 102009016867 A1 describes a device for storing electrical energy with a heat conducting device which is suitable for supplying heat to this cell and / or removing it from it.
- Measuring device detects the temperature at a predetermined location, and a second measuring device detects the strength of the electric current.
- Control device determines the temperature difference from this detected temperature and a predetermined temperature and switches, depending on the measured temperature, the detected temperature difference and a detected current, a heat conducting device and a conveyor for a fluid on or off.
- An object of the present invention may be seen to further improve the properties of known devices and a method of cooling an electrochemical energy store. This object is achieved by a product or a process according to one of the independent

- Magnetic particles suspended in a carrier liquid preferably in water or oil. Particularly preferably, these particles consist of a material with thermocaloric properties.
- the preferably solid particles are preferably stabilized with a polymeric surface coating.
- Ferrofluids are preferably stable dispersions in which the solid particles do not settle over time and also in extremely strong ones Magnetic fields do not accumulate on each other or separate from the liquid as a separate phase.
- the book "Ferrohydrodynamics" (EA 1985, Ronald E. Rosensweig: Ferrohydrodynamics, Dover Publications, Mineola NY 1997, ISBN 0-486-67834-2) by Ronald Rosenzweig introduces into the matter of ferrofluids.
- MRF magnetorheological fluid
- magnetorheological fluids consist of a suspension of micrometer sized magnetic particles larger than the typically nanometer sized particles of ferrofluids.
- the larger particles of the MRF tend to form chains when exposed to a magnetic field.
- the viscosity (“toughness") of the MRF is increased so that it may even solidify, especially if a compressive force on it is not large enough to break the chains, unlike a magnetorheological one
- Liquid forms a ferrofluid, preferably no chains.
- Ferrofluids are preferably superparamagnetic and have low to very low hysteresis.
- the particles are preferably of iron, magnetite or cobalt and are preferably smaller than a magnetic domain, typically 5-10 nm (nanometers) in diameter.
- Surfactants are preferably added to the suspension stabilize by the particles bound in micelles due to steric interactions repel each other.
- Superparamagnetism also called a superparamagnetic effect, describes the magnetic properties of very small particles of a ferromagnetic material, which do not maintain a permanent magnetization even at temperatures below the Curie temperature, when a previously applied magnetic field has been switched off. This phenomenon is based on the so-called Brown relaxation and on the so-called Neel relaxation, through which the magnetic moments of the particles by thermal influences (without the influence of a magnetic field) change.

- the magnetocaloric effect is a phenomenon in which a material heats up when exposed to a strong magnetic field and cools when the magnetic field is removed. The effect arises from the orientation of the magnetic moments of the material through the magnetic field, which in turn decreases with decreasing magnetic field.

It is particularly suitable for low ambient temperatures, for example in winter, also for temperature control of the battery. Preferably, this is done by the cooler in the secondary circuit by a three-way valve, preferably with actuator, is decoupled from the secondary circuit. In this operating state, the second coolant circulates past the radiator of the secondary circuit in the secondary circuit. The heat generated by irreversibilities remains in this mode Secondary circuit from where it can be delivered via the primary circuit to the battery.
- the first magnetic field is at least partially generated by an electromagnet, which is supplied at least partially and / or temporarily by the electrochemical energy store with power.
- Magnetic field with which the properties of the magnetic cooling liquid are influenced, can be easily controlled or influenced by a suitable change in the magnetic field strength and / or direction of the magnetic field. If the current required to generate the magnetic field can be taken from the electrochemical energy store, cooling of the electrochemical energy store by the magnetic cooling liquid is also possible if no external power source is available. This is the case in particular in mobile applications, for example in vehicle technology. According to a further preferred embodiment of the invention, whose

A distinction is made between free or natural convection, in which the transport of particles is solely due to the effects of the
- Temperature gradients that is caused for example by up or down of the fluid due to the density differences caused by the temperature change, from the forced convection, in which the particle transport by external action, for example a blower or a pump is caused.
- Free convection due to thermal density differences is due to the fact that substances usually expand when heated. Under the influence of the gravitational force within a fluid areas of lower density rise against the gravitational field (buoyancy), while areas of higher density fall into it.
- the first cooling liquid at least temporarily flows through a first heat exchanger, in which the first cooling liquid exchanges heat with a second cooling liquid passing through a secondary circuit flows.
