Description:FIELD OF THE INVENTION
[0001] The present invention relates to a battery pack. More particularly but not exclusively the present subject matter relates to thermal management of the battery pack by degassing of the battery pack.
BACKGROUND OF THE INVENTION
[0002] With the advancement in technology, an electric or a hybrid electric vehicle makes use of one or more power sources to drive the vehicle. The one or more powers source is a battery pack to provide power to run a motor which in turn runs one or more wheels of the vehicle. The one or more power sources in such hybrid electric vehicles are prone to damage due to increase in temperature as the usage increases.
[0003] The increase in temperature of the battery pack leads to poor performance of the vehicle and causes thermal runaway, which creates an unsafe driving condition for a user. Thermal runaways are caused due to an abnormal increase in temperature inside the battery pack which may lead to melting or excessive damage to a plurality of cells of the battery pack and may even cause the plurality of cells of the battery pack to explode. There is a greater risk of fire and explosion, caused due to the chemical reactions taking place inside the battery pack.
[0004] In the case of charged Li-ion cells with high energy density, the thermal runaway is a fast, violent, self-accelerating chemical reaction of electrodes and electrolyte which releases high amounts of heat and gas. A better cooled battery pack ensures the welfare and safety of the user and as well as leads to an increase in durability and health of the plurality of cells of the battery pack.
[0005] Existing small cell batteries are constrained by housing of the battery pack. When a small cell Li-ion battery pack is charged, it causes the electrodes to expand. The expansion results in added mechanical stress on the electrodes, which leads to a shorter life cycle of the battery pack. Moreover, due to the increased need of storage capacity of the battery pack, additional active anode and cathode materials are inserted into the housing of the battery pack, which further contributes to an increase in mechanical stress. Therefore, there is a compromise between performance of the battery pack and capacity of the battery pack.
[0006] Existing large cell batteries are disadvantageous due to safety concerns. The energy released in the large cell of the battery that are undergoing thermal runaway is directly proportional to the amount of an electrolyte available in the plurality of cells. The amount of electrolyte for larger cells is substantially greater than smaller cells, thereby large cell batteries can gain more momentum during thermal runaway which makes them less secure. Once a large cell is in thermal runaway mode, the heat generated by the cell triggers a thermal runaway reaction in the adjacent plurality of cells, causing the battery pack to be explode, with massive destruction to peripheral devices.
[0007] Conventionally, battery packs are sealed in a housing to ensure that the battery pack is waterproof and dustproof, since interference of foreign particles in the battery pack may adversely affect the performance of the battery pack. However, altitude changes can affect the battery pack, causing abnormal changes in internal pressure and external pressure of the battery pack. Substantially high or low air pressure inside the battery pack may cause structural damage to the sealing surface of the battery pack, resulting in battery pack failure.
[0008] In addition to this, thermal runaways create build-up of pressure and gasses in the battery pack. Such pressure must be relieved to avoid damage and explosion due to thermal runaway. Therefore, a compromise must be met between sealing of the battery pack and relieving pressure inside the battery pack.
[0009] In general, a venting structure is provided on a side portion of the housing to evacuate pressure from an internal region of the battery pack. The heated gas and the air inside the battery pack tends to rise upwards towards the top of the battery pack due to high temperature. Therefore, the venting structure at the side cover of the housing of the battery pack does not enables fluent or easy escape of the heated gas from the inside region of the battery pack to the outside atmosphere.
[00010] Furthermore, a phase change material (PCM) is used in the battery pack. The PCM is a semi solid material which extracts heat from the plurality of cells, thus assists in maintaining optimum temperature of the battery pack for efficient functioning. When the temperature of the battery pack increases, the PCM changes its state from the semi solid to a liquid state. Due to which the side covers come in contact with the liquid PCM. Thus, the venting structure at the side cover of the housing, also comes in contact with the liquid PCM, which makes it further difficult for the venting structure to enable easy passage of the gases from the internal region of the battery pack to an external atmosphere.
[00011] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

For example, the teachings presented and the needs of a particular application may yield multiple alternative and suitable approaches to implement the functionality of any detail described herein. Therefore, any approach may extend beyond the particular implementation choices in the following embodiments described and shown.
[00016] References to “one embodiment,” “at least one embodiment,” “an embodiment,” “one example,” “an example,” “for example,” and so on indicate that the embodiment(s) or example(s) may include a particular feature, structure, characteristic, property, element, or limitation but that not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Further, repeated use of the phrase “in an embodiment” does not necessarily refer to the same embodiment.
[00017] The present invention now will be described more fully hereinafter with different embodiments. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather those embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the invention to those skilled in the art.
[00018] The present invention is illustrated with a battery pack. However, a person skilled in the art would appreciate that the present invention is not limited to a battery pack and certain features, aspects and advantages of embodiments of the present invention can be used with other types and forms of energy storage devices or energy storage packs used in conjunction with various types of vehicles such as electric vehicle and plug-in hybrid vehicles as well as other electrical equipment and external electrical loads using a rechargeable energy storage pack. In an embodiment, the electric vehicles, hybrid vehicle, electrical equipment, external electrical load draw electric current from the energy storage pack.
[00019] When the battery pack is used for a long time, or while heavy usage of the battery pack, the plurality of cells tends to generate heat and gasses. If proper degassing of the battery pack is not executed in the battery pack, there are high probability that the battery pack could experience thermal runaway. In case the thermal runaway of the battery pack is not controlled swiftly within optimum time, the battery pack might be prone to explosion or accident-causing severe danger to the surrounding and the user of the battery pack.
[00020] As per known state of art, the degassing of the battery packs can be done by the venting structures. However, the venting structures are disposed such that it fails to enable easy evacuation of the hot gasses from the internal region of the battery due to misaligned direction of the venting structure, and obstructions due to other components of the battery pack. The present invention addresses this exact drawback of the known art by disposing the venting structure which direct gases from an internal region of the battery pack to an external atmosphere in most swift manner, allowing the battery pack to prevent thermal runaway. The inefficient degassing of the battery pack poses a danger of accident and damage which the present subject matter appositely solves.
[00021] Therefore, it is an object of the present subject matter to provide a battery pack comprising of a housing configured to accommodate a venting structure such that the venting structure can swiftly direct the gases from an internal region of the battery pack to an external atmosphere with optimum efficacy, thereby ensuring optimum performance, and durability of the battery pack.
[00022] It is a further object of the present subject matter to provide a top cover for a battery pack, which is configured to accommodate the venting structure that can swiftly direct the gases from an internal region of the battery pack to an external atmosphere with optimum efficacy, thereby ensuring optimum performance, and durability of the battery pack.
[00023] To this end, the present subject matter discloses the battery pack comprising a housing, that is configured to house at least the plurality of cells of the battery pack. The housing comprises a top cover which covers a top portion of the battery pack. The top cover is configured with a first depressed portion on an upper portion of the top cover. The first depressed portion is configured to accommodate a venting structure, wherein the venting structure is configured to direct gases from an internal region of the battery pack to an external atmosphere. Thus, in the case of usage of the battery pack for a longer duration or during heavy usage, the gasses generated at an internal region of the battery pack have high temperature. Due to high temperature of the gases, the gases tend to rise upwards towards the upper portion of the battery pack. Thus, the venting structure which is disposed on the top cover of the battery pack, enables easy and swift evacuation of the heated gases from the internal region of the battery pack to the external atmosphere. Consequently, the battery pack prevents thermal runaway of the battery pack, thereby preventing accidental damages that could arise from the battery pack.
[00024] In accordance with the configuration of the top cover, the top cover has a left portion, and a right portion, wherein the first depressed portion for accommodating the venting structure is disposed at a portion opposite to a connector of the battery pack, wherein the connector is disposed at one of the left portions, and the right portion. The first depressed portion being dipped towards the internal region of the battery pack, thereby does not interfere with the BMS, the bus bar, the plurality of interconnectors and other components of the battery pack. Thus, this also prevents the venting structure from interfering with the other components of the battery pack such as PCM, or electrolytes etc. Consequently, the top cover of the battery pack enables accommodating the venting structure such that the heated gases from the internal region of the battery pack can be directed towards the external atmosphere without obstructions from any other components of the battery pack.
[00025] Furthermore, the venting structure also comprises a top portion, an intermediary portion, and a base portion, wherein the intermediary portion is configured with one or more opening structures configured to direct gases from the internal region of the battery pack to the external atmosphere. The depth of the first depressed portion is configured to form a flushed profile with the base portion of the venting structure. The intermediary portion of the venting structure is disposed at an equal or at a higher level to a non-depressed portion of an upper portion of a top cover. As per yet another embodiment of the present invention, the depth of the first depressed portion is configured to be in a range of 2 millimeter-3 millimetre. The flushed profile of the first depressed portion with the base portion of the venting structure prevents the venting structure from protruding . Thus, this enables easy packaging, and ensuring compactness of the battery pack.
[00026] As per an embodiment of the present invention, the upper portion of the top cover comprises a second depressed portion at a proximity to a connector of the battery pack. The second depressed portion is configured to accommodate a heat sink structure of the battery pack. Since, a MOSFET of the battery pack is disposed in a proximity of the connector, and the MOSFET is in close proximity with the housing of the battery pack thus, the second depressed portion accommodating the heat sink enables evacuation of heat from the MOSFET or other parts of the battery pack to the external atmosphere.
[00027] According to embodiments illustrated herein, the present invention also discloses a top cover for the battery pack, wherein the top cover is configured with a first depressed portion on an upper portion of the top cover. The first depressed portion is configured to accommodate a venting structure. The venting structure is configured to direct gases from an internal region of the battery pack to an external atmosphere. Thus, in the case of usage of the battery pack for a longer duration or during heavy usage, the gasses generated at an internal region of the battery pack have high temperature. Due to high temperature of the gases, the gases tend to rise upwards towards the upper portion of the battery pack. Thus, the venting structure which is disposed on the top cover of the battery pack, enables easy and swift evacuation of the heated gases from the internal region of the battery pack to the external atmosphere. Consequently, the top cover prevents thermal runaway of the battery pack, thereby preventing accidental damages that could arise from the battery pack.
[00028] In accordance with the configuration of the disclosed subject matter, an additional advantage of the disclosed battery pack is the flexibility to manufacture variants in forms of size of the battery pack, range of power supply and capacity of the battery pack.
[00029] Further, the disclosed subject matter relating to the top cover of the battery can be easily implemented in traditional battery pack and energy storage pack configuration and layout without significant manufacturing deviations. The disclosed subject matter enables modified versions of existing battery packs with minimal changes in the battery pack design, electrical connections in the battery pack and even the manufacturing set-up without major revamping of the core manufacturing process.
[00030] Further, the disclosed subject matter relating to the battery pack and the eases and enhances the accessibility, serviceability, and maintenance of the venting structure. The configuration of the known art further apprehensively impacts the serviceability, maintainability, and accessibility of the venting structure of the battery pack as already known in the prior art.

The first depressed portion (106) is configured to accommodate the venting structure (104) and the second depressed portion (108) is at a proximity to the connector (110) of the battery pack (100). As per an embodiment of the venting structure (104) comprises a top portion (304), an intermediary portion (306), and a base portion (308). The intermediary portion (306) is configured with one or more opening structures, configured to direct gases from the internal region of the battery pack (100) to the external atmosphere.
[00041] As per an embodiment of the present invention, a depth (302) of the first depressed portion (106) is configured to form a flushed profile or a continuous profile with the base portion (308) of the venting structure (104). In other words, the depth of the first depressed portion (106) is substantially equal to the base portion (308) of the venting structure (104). The intermediary portion (306) of the venting structure (104) is disposed at an equal or at a higher level to the non-depressed portion (300) of an upper portion of a top cover (102a). This enables the one or more opening structures to enable direct gases from the internal region of the battery pack (100) to the external atmosphere without heating up the first depressed portion (106). As per yet another embodiment of the present invention, the depth (302) of the first depressed portion (106) is configured to be in a range of 2 millimeter-3 millimetre.
