Specification

Description:FIELD
The present disclosure relates to a component for a battery pack assembly, and more particularly relates to a cover plate for mounting a cooling plate to a frame case of a battery pack assembly.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Typically, lithium-based rechargeable batteries are widely used as a power source for electric vehicles, or hybrid electric vehicles or any other applications. These batteries comprise a plurality of battery cells, or a battery pack, tightly packed into a case frame. Therefore, it is necessary to improve the safety features of the battery pack assembly to hold the battery cells at a desired ideal temperature: since, the temperature of the battery pack increases while charging and discharging, which may cause damage to the battery pack assembly.
Therefore, to suppress the temperature rise of the battery pack assembly, a cooling plate is fastened, abutting to an operative surface of the battery cells of the battery pack. The cooling plate has a structure where a plurality of channels is provided for the coolant to flow. Thereby, the temperature of the battery pack is lowered by the movement of the coolant through the plurality of channels. Since the cooling plate is a crucial component of the battery pack, therefore it is required to protect it from external shock or impact.
Therefore, to safeguard the cooling plate from the external impact, an aluminum extrusion frame with steel or aluminum cover plate is being utilized. Conventionally, the steel or aluminum cover plate are directly mounted to a housing. However, the direct mounting of the cover plate without having sufficient clearance with cooling plate cannot sustain the sudden or impact load of the road and the impact gets transmitted to the cooling plate thereby damaging the channels of the cooling plate and the battery pack. Also, to effectively mount the cover plate over the cooling plate, it is required to re-route the cooling channels to accommodate the packaging space for mountings or fasteners, which results in uneven distribution of the coolant across channels and thus, results in a non-uniform cooling of the battery pack assembly.
Further, to mount the cover plate over the cooling plate, conventionally a long straight reinforcement member is being utilized. The straight reinforced member is arranged over the channels of the cooling plate and then the cover plate is mounted to the cooling plate. However, such type of mounting increases the overall height of the battery pack which in-turn increases the overall dimension and weight of the battery pack assembly.
Thus, there is felt a need of a cover plate for a cooling plate of a battery pack assembly that alleviates the aforementioned drawbacks.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
An object of the present invention is to provide a cover plate for a cooling plate of a battery pack assembly.
Another object of the present invention is to provide a cover plate for a cooling plate that facilitates ease of mounting of a reinforcement member.

Still another object of the present invention is to provide a cover plate for a cooling plate that reduces the weight of the battery pack assembly.
Yet another object of the present invention is to provide a cover plate for a cooling plate that facilitates uniform temperature distribution of the cooling plate.
Still another object of the present invention is to provide a cover plate for a cooling plate that avoids re-routing of the cooling channels.
Yet another object of the present invention is to provide a cover plate for a cooling plate which requires minimal space for mounting.

Typically, to safeguard the cooling plate from the external impact, an aluminum extrusion frame with steel or aluminum cover plate (100’) is being utilized. Figure 1 illustrates a plurality of cooling channels (90a) provided on a cooling plate (90’). Figure 2a illustrates a conventional cover plate (100’) with a long straight reinforcement member (44) attached with the cover plate (100’) and Figure 2b illustrates a sectional view of mounting of a conventional cover plate (100’) with the long straight reinforcement member (44) mounted to the conventional cover plate (100’) by means of fasteners. Conventionally, the steel or aluminum cover plate (100’) is directly mounted to a housing. However, the direct mounting of the cover plate (100’) without having sufficient clearance with cooling plate (90’)cannot sustain the sudden or impact load of the road and the impact gets transmitted to the cooling plate (90’) and the battery pack, and thus disturbs the assembly. Also, to effectively mount the conventional cover plate (100’) over the cooling plate (90’), it is required to re-route the cooling channels (90a) to accommodate the packaging space for mountings, which results in un-even distribution of the coolant across the channels (90a) and results in a non-uniform cooling of the battery pack assembly.
