Definitions
- the present invention relates to a control device for a battery storage device.
- This Bat terie appointment contain as closed units in addition to battery cells or battery modules and elements for the electrical interconnection of these modules also a control device, which is usually arranged in a separate housing section or completely separate housing within the battery storage.
- a control device is equipped with electronic components, for example battery management system, current measuring shunt, and electromechanical components, for example in the form of contactors, fuses, busbars, connectors, etc.
- electronic components for example battery management system, current measuring shunt, and electromechanical components, for example in the form of contactors, fuses, busbars, connectors, etc.
- such a control device is housed in a separate housing section or even an additional closed Ge housing separately from the cells of the battery store for safety reasons.
- redundant units can be provided in the control device.
- excessive heating of an electrical fuse requires so-called "derating", i.e. a design for a higher tripping current.
- the electrical components used must therefore be deliberately oversized in order to take account of the higher temperatures in the event of high loads Alternatively, a higher probability of failure can be accepted.
- the above-mentioned constructive solution approaches generate a higher space requirement and result in higher costs, provided that the generally tight spatial conditions in a module housing can be implemented at all. A shortened service life also leads to increased costs and reduced reliability and therefore cannot be seriously considered as a solution.
- the object of the present invention is therefore to create a control device in which a predetermined service life can be reliably achieved without overdimensioning components.
- a closed housing is formed to form free and / or forced convection through which temperature differences within the housing and also across the control device can be compensated.
- the invention is therefore essentially based on the knowledge that the formation of heat nests is beneficial in that natural or free convection can hardly develop within the closed housing of the control device.
- a corresponding design of the closed housing by means of which the formation of free and / or forced convection is made possible, strongly counteracts the formation of pronounced heat pockets. This means that at least temperature differences within the housing are compensated, so that the components can work in normal thermal operation.
- a support part is formed as the basis of the control device within the closed housing so that this support part along a longitudinal extent or in the longitudinal direction of the housing from a bottom of the closed housing is lifted off as part of a module housing forms a free flow cross-section.
- an inlet of the free flow cross section forms a direct receptacle for a device fan, which is in particular actively driven and, if necessary, also electrically controlled.
- an opening is provided between a lower part formed by the support part and an upper part of the closed housing of the control device, which opening is arranged at an end of the support part opposite the device fan. This results in a maximum length of a free flow cross-section available for convection within the closed housing of the control device. This flow path runs almost closed around the support part.
- a drive from the heat absorbed by convection of the control device is provided through a heat exchanger.
- the aim is not only to evenly distribute heat loss via the control device, but convectively absorbed heat is also specifically dissipated from the closed housing of the control device.
- an underside of the free flow cross section is designed directly as a heat exchanger or for passing over a cooling plate of the battery modules of the battery storage unit concerned.
- the support part is preferably designed as a plastic support in such a way that its support geometry does not only well accommodate, support and support the components mentioned above by way of example can fix, but at the same time also forms a bulkhead between an upper and a lower volume of the closed Ge housing, with the plastic carrier on the side opposite the upper side carrying the due components, openings for air to flow from the lower half of the housing into the upper half Has housing half.
- these openings are also arranged directly under particularly lossy components, in particular fuses or shunts, for targeted cooling by convection.
- a directed flow is generated within the entire ge closed housing section. Heat nest formation is effectively avoided.
- the extended battery module cooling plate By passing over the extended battery module cooling plate, there is a direct heat exchange between the circulated air and the cooling system. Components that are particularly lossy can also be cooled more intensively by means of dedicated discharge openings provided directly under these components. It is even possible to use a plastic housing that is closed all around the control device.
- a support part in the form of a plastic carrier is created as the basis of the control device and thus as an essential part within the closed housing, the support part
- a. is designed as an electrically insulating plastic component, preferably as an injection-molded part;
- d. has a receptacle for a case fan
- f. has a flow cross-section that is open on an underside to a cooling plate, and extends in the longitudinal direction from one end of the volume to the other end in order to transport an air flow and to enable heat exchange to the cooling plate below .
- the closed housing of the control device forms with a support part of the type mentioned a system with advantageously minimal housing volume, comprising a lower plastic carrier and air guide plate, an upper plastic plate, electrical components to be cooled, a housing fan mounted on or on the support part and liquid-filled cooling plates, which are provided spread out under the lower plastic support.
- the support part thus has a be fitted top and an unpopulated bottom, wherein the bottom is designed to be arranged opposite a heat exchanger in an installation position.
- FIG. 1 a perspective view of part of a battery storage unit with a control unit and a plurality of electrical storage cells
- Figure 2 a side view of the battery storage of Fi gur 1 and
- Figure 3 a view of a longitudinal side of Figure 1 in one
- FIG. 1 shows a perspective view of a part of a battery storage device 1 with a control device 2 and a plurality of electrical storage cells 3.
- the control unit 2 is physically separated from the storage cells 3 by a module housing 4 in its own housing 5 that is closed with respect to the other battery storage device 1.
- the closed housing 5 not only components of the electronics, eg an electronic battery management system BM with power semiconductors and current measuring shunts, but also components of the electromechanics eg in the form of contactors, fuses Si, busbars S and connectors.
- the closed housing 5 is designed to form free and / or forced convection. As a result of the convection, temperature differences within the housing 5 can be compensated for to the extent that all construction parts are operated in normal temperature ranges and can therefore achieve their specified service life. In addition to increased costs, this also effectively saves installation space, which is always very rare.
- FIG. 2 shows a side view of the battery storage 1 of Figure 1, indicated by arrows of a convection curve within the closed housing 5 of the control device 2.
- a support part 6 which is a base for the Control device 2 within the closed housing 5 forms, as a mechanical carrier of all components and fixation within the closed housing 5.
- the support part 6 is designed in the form of a plastic component so that it is along a longitudinal axis or in the longitudinal direction of the housing 5 from a Lifted bottom B of the module housing 4 forms a free flow cross section 7.
- the support part 6 has formed supports or legs, which are hardly recognizable in the drawing due to the dense assembly of the support part 6 with numerous components of the control device 2 in an installation position, and separates egg NEN upper part oT from one like a bulkhead lower part uT of the volume of the closed housing 5 for the control device 2.
- the lower part uT now closes a circuit of convection as a free flow cross section 7.
- a receptacle is at a passage of the free flow cross section 7 provided, on which an electrically actively driven, regulated device fan 8 is arranged.
- an opening 9 is provided between the lower housing part uT and the upper part oT of the closed housing 5 of the control device 2, which opening is arranged on an end of the support part 6 opposite the device fan 8.
- a flow can thus develop essentially over an entire longitudinal extension of the closed housing 5.
- an underside of the free flow cross section 7 is designed directly as a heat exchanger 10 by passing over a cooling plate 11 of the battery modules or electrical storage cells 3.
- Figure 3 shows a view of a longitudinal side of Figure 1 in a sectional view and underlines the obviously optimized use of the usually.
