Description

A package for accommodation and cooling of an electrical energy storage BACKGROUND OF THE INVENTION AND PRIOR ART The present invention relates to a package for accommodation and cooling of an electrical energy storage according to the preamble of claim 1.
Hybrid vehicles and pure electric vehicles may comprise an electric machine which alternately works as motor and generator, an electric energy storage for storing of electrical energy and power electronics for controlling the flow of electrical energy between the electrical energy storage and the electric machine. The electrical energy storage has an optimal efficiency within a relatively low temperature range.
Furthermore, an electrical energy storage should not be heated to a temperature above a maximum temperature for safety reasons. Consequently, it is important to provide an efficient cooling of the electrical energy storage during operation.
The electrical energy storage may comprise a plurality of battery modules each including a number of rectangular battery cells. Traditionally, battery modules comprising such battery cells are arranged on a cooling plate and they are cooled from the underside by a coolant circulating in heat transferring contact with the cooling plate. The battery modules may be fasten to the cooling plate by screw connections. However, screw connections are heavy and space consuming. Furthermore, the mounting process of the battery modules is relatively complicated and time wasting.
US 2013/0202940 shows a battery module fixedly arranged on a cooling plate such that a lower side of the battery module is in direct contact with an upper surface of the cooling plate by a fixing system comprising two rails running at a distance from each other.
US 2016/0268656 shows a plurality of battery modules fixedly mounted on a top surface of a cooling plate. The battery modules are fixedly mounted on the cooling plate by means of brackets which are arranged on the lengthwise sides of the cooling plate.
SUMMARY OF THE INVENTION The object of the present invention is to provide a package for accommodation and cooling of an electrical energy storage in which the including components are fixedly mounted in relation to each other in a simple manner.
The above mentioned object is achieved by the package defined in claim 1. Thus, the package comprises at least two housing parts enclosing the electrical energy storage, at least one cooling plate and at least one gap pad which is arranged in an interface between the cooling plate and the electrical energy storage. Said interface between the cooling plate and the electrical energy storage has a shape preventing relative sliding movements between the cooling plate, the gap pad and the electrical energy storage when they are in a connected state. Furthermore, the housing comprises at least two housing parts which in a closed position are configured to provide a clamping force which holds the cooling plate, the gap pad and the electrical energy storage in a connected state. Consequently, when the at least two housing parts are in a closed position, the cooling plate, the gap pad and the electrical energy storage are held in fixed positions in relation to each other. The mounting process of the package is simple. Furthermore, the above mentioned design of the including components makes it possible to provide a light and compact package.
According to a first alternative, said interface between the cooling plate and the electrical energy storage comprises a separate locking member configured to be introduced into a recess in the cooling plate and a recess in the electrical energy storage. Such a locking member prevents in a very simple manner relative sliding movement between the cooling plate and the electrical energy storage when they are in a connected state. A remaining part of the interface between the cooling plate and the electrical energy storage may be defined by plane surfaces.
Alternatively, the interface between the cooling plate and the electrical energy storage comprises a projecting member in the cooling plate to be introduced into a recess in the electrical energy storage. When the projecting member of the cooling plate is introduced into the recess of the electrical energy storage, relative sliding movements between the cooling plate and the electrical energy storage are prevented in a very simple manner when they are in a connected state. Alternatively, the interface between the cooling plate and the electrical energy storage comprises a projecting member in the electrical energy storage configured to be introduced into a recess in the cooling plate.
According to an embodiment of the invention, the package comprises cooling plates on opposite sides of the electric energy storage. In this case, the electrical energy storage obtains an excellent cooling. Such an electric energy storage may comprise a first surface to be in contact with a first cooling plate, a second surface to be in contact with a second cooling plate and a third surface, which is arranged between the first surface and the second surface, comprising electrical connecting members.
According to an embodiment of the invention, the at least two housing parts comprise two opposite end walls which are configured to provide said clamping force on the cooling plate, the gap pad and the electrical energy storage when the housing parts are in a closed position. Said clamping force ensures the cooling plate, the gap pad and the electrical energy storage always are in a connected state when the housing parts are in the closed position.
According to an embodiment of the invention, said two housing parts have an identical design. In this case, the manufacturing process of the housing parts is facilitated.
However, it is possible to use housing parts of different design. It is also possible to use more than two housing parts.
According to an embodiment of the invention, said housing parts are arranged in the closed position by releasable connecting members. The releasable connecting members may be screws, bolts etc.
According to an embodiment of the invention, said housing has an inner space of a size and shape corresponding to the outer circumference surface of the cooling plate. In this case, it is possible to prevent sliding movement of the cooling plate in the housing which is a prerequisite for fixing the electric energy storage in a fixed position in the housing.
According to an embodiment of the invention, the electrical energy storage comprises battery packages. Each battery package may comprise a plurality of rectangular battery cells which have been bundled together. The battery packages may be arranged in parallel rows. In this case, it is possible to arrange the battery modules in a very compact manner in the electric energy storage. Furthermore, it is possible to stack more electric energy storage on each other in the housing with intermediate cooling plates.

The first set of gap pads 4 are arranged in the first interface Ai in different positions between the first cooling plate 2 and the battery modules 1. The first surface 3 a of the second cooling plate 3 and the second contact surface lb of the battery modules 1 define a second interface A2between the second cooling plate 3 and the battery modules 1. The second set of gap pads 4 are arranged in the second interface A2in different positions between the first surface 3 a of the second cooling plate 3 and the second contact surface lb of the battery modules 1. Each battery module 1 comprises a third surface lc including electrical connection members Id. The third surface lc constitutes a side surface arranged between the contact surfaces 1a, 1b. A first separate locking pin 9 is configured to be arranged in a recess 10 in the first cooling plate 2 and in a corresponding recesses 11 in each battery module 1. A second separate locking pin 9 is configured to be arranged in a recess 12 in each battery module 1 and in a recess 13 in a corresponding position in the second cooling plate 3.
During mounting of the package, the second cooling plate 3 is arranged on an inner surface of the end wall 6a of the second housing part 6. An inner surface of the side walls 6b of the second housing part 6 has a corresponding shape and size as an outer circumference surface of the second cooling plate 3. Thus, the second cooling plate 3 is arranged in a fixed position in the second housing part 6. After that, the second set of gap pads 4 are arranged on the first surface 3 a of the second cooling plate 3 in predetermined positions. Second locking pins 9 are arranged the recesses 13 in the second cooling plate 3. The battery modules 1 are arranged individually or in groups on the gap pads 4 in positions such that each second locking pin 9 is introduced into a recess 12 in the respective battery modules 1. The second locking pin 9 provides a design of the second interface A2preventing relative sliding movements between the second cooling plate 3, the gap pads 4 and the battery modules 1 when they are in a connected state.
