Description

Technical Field

[0001] The present invention relates to a battery pack arrangement for a vehicle, in particular a partially or fully electric vehicle. The present invention also relates to a frame arrangement comprising such a battery pack arrangement. In addition, the present invention relates to a vehicle comprising such a frame arrangement and a battery pack arrangement. The present invention is applicable to trucks, cars, buses and work machines in the field of industrial construction machinery or construction equipment, in particular partially or fully electric vehicles and work machines. Although the present invention will be described with respect to trucks, the present invention is not limited to this particular machine, but can also be used for other vehicles (e.g. work machines, wheel loaders, articulated haulers, excavators, backhoe loaders), and other vehicle types (e.g. buses, cars, self-driving cars, etc.). In addition, the present invention can be used for many different types of electric vehicles, such as fully electric vehicles, partially electric vehicles, such as hybrid vehicles and vehicles with internal combustion engines and motors, with fuel cells and motors, etc. Background Art

[0002] In the field of batteries and battery systems for vehicles, such as partially and fully electric vehicles, there are several different types of arrangements for storing batteries in the vehicle and for connecting the batteries to other components of the vehicle's electrical system, including, for example, the electric propulsion system.

[0003] Batteries in partially and fully electric vehicles are used not only to power the vehicle but also to power other electrical systems, so there is an increasing need for batteries that provide sufficiently high power to ensure reliable operation of the vehicle. Such batteries are most often rechargeable batteries and consist of several battery cells that can be connected in series and / or in parallel to form a complete battery pack for the vehicle. With regard to the arrangement of batteries in a vehicle, it has been observed that there are challenges in positioning the batteries relative to other systems and components of the vehicle due to space and performance related requirements.

[0004] Furthermore, with respect to these types of vehicles, effective temperature control of the battery is critical to ensuring reliable operation of the battery in ordinary use of the vehicle. For example, a battery temperature that is too high may reduce its performance and also shorten its life. Therefore, thermal management of the battery and other electrical systems is critical to the performance and life of the system. In other words, the placement of the battery in the vehicle depends not only on the available space in the vehicle, but also on the possibility of ensuring that the battery can be placed in the vehicle to operate under healthy conditions, including, for example, healthy operating temperatures.

[0005] In view of the foregoing, it is desirable to improve the placement of batteries in vehicles in order to provide reliable operation of the vehicle and its electrical systems.

[0006] One conventional type of arrangement of battery packs in vehicles is to position a cooling plate inside a substantially horizontally oriented and rectangularly shaped battery pack. US2017 / 0288285A1 discloses another type of battery pack arrangement in which a liquid-cooled battery pack includes two groups of batteries cooled by an internal common channel. As an example, FIG. 11 thereof discloses a battery housing assembly. The housing includes two parts including a battery cell cover wall. In addition, a bracket may be attached to a portion of the battery cell cover wall. Coolant may be provided to and removed from the housing at a coolant inlet / outlet. In addition, a plurality of battery cell connection circuits may be disposed on opposite sides of a common coolant channel and in parallel with the common coolant channel. The common coolant channel may be oriented vertically within the housing to facilitate fluid circulation through the channel.

[0007] Despite activity in this area, there remains a need for further improvements in the arrangement of batteries in vehicles, such as partially or fully electric vehicles, while maintaining a balance between cost, the number of components making up the arrangement and the space available in the vehicle. Summary of the invention

[0008] An object of the present invention is to provide a battery pack arrangement for a vehicle, such as a partially or fully electric vehicle, the arrangement being intended to improve the packaging efficiency of the battery pack arrangement in the vehicle while maintaining effective thermal management control of the battery modules that constitute the battery pack arrangement. The object is achieved at least in part by a battery pack arrangement according to the present invention. According to a first aspect of the present invention, a battery pack arrangement is provided, the battery pack arrangement comprising a battery pack having a first battery module, a second battery module and a thermal management component, the first battery module having a first group of battery cells, the second battery module having a second group of battery cells, and the thermal management component being arranged between the first battery module and the second battery module. The first battery module and the second battery module are arranged on opposite sides of the thermal management component. The thermal management component has a first thermally conductive surface for regulating the temperature of the first battery module and a second thermally conductive surface for regulating the temperature of the second battery module.

[0009] Furthermore, the battery pack arrangement includes a suspension attachment configured to attach the battery pack arrangement to a frame of a vehicle in a generally vertical orientation. By having a suspension attachment according to an example embodiment, the battery pack arrangement may be mounted to a frame of a vehicle in a generally vertical mounting manner.

[0010] Furthermore, by means of exemplary embodiments of the present invention, it is believed that an optimized battery pack arrangement for a vehicle frame is provided in terms of space, design and flexibility. That is, the battery pack arrangement allows modularity and flexibility, because the battery pack arrangement can be more easily adjusted to different types of vehicles with different wheelbases, and even includes a combination of a group of battery packs, so that it can be customized for a specific type of vehicle, such as a heavy vehicle with certain restrictions in terms of wheelbase, etc. In this case, it is believed that the measure of providing a thermal management member between the first battery module and the second battery module at least partially contributes to the modularity and flexibility and compactness of the battery pack arrangement. For example, since the battery module is connected to the thermal management member, it is not necessary to detachably attach each of the battery modules to the vehicle frame. Therefore, the thermal management member provides a mechanical structure for the battery module, and the arrangement of the battery module to the thermal management member provides modularity and flexibility, and also ensures a sufficient level of temperature control of the battery pack. Furthermore, exemplary embodiments provide a method for quickly installing a battery pack arrangement on a vehicle in a mass production manner.

[0011] To this end, the thermal management component is configured to serve as a load-bearing structure by arranging the first battery module and the second battery module on opposite sides of the thermal management component. That is, the thermal management component is arranged as a load-bearing structure for the battery module. Typically, the thermal management component is arranged in a vertical orientation along the first and second battery modules. Therefore, the thermal management component is a load-bearing vertical thermal management component. Although the thermal management component is typically configured to cool the battery modules, the thermal management component can also be configured to heat the battery modules if the temperature of one or both of the battery modules drops below a critical temperature.

[0012] By providing a thermal management component having a first thermally conductive surface for regulating the temperature of the first battery module and a second thermally conductive surface for regulating the temperature of the second battery module, the thermal management component is configured to cool and / or heat the oppositely arranged first and second battery modules, respectively.

[0013] The exemplary embodiments are particularly useful for electric vehicles, such as electric trucks, electric buses, etc., ie, fully electric machines. However, the exemplary embodiments may also be installed in partially electric vehicles, such as hybrid vehicles.

[0014] According to an exemplary embodiment, the battery pack has a first longitudinal outer recess for accommodating a portion of the vehicle frame and a second longitudinal outer recess for accommodating another portion of the vehicle frame. An exemplary advantage of a battery pack having such an outer recess is that the battery pack arrangement can be attached to the vehicle frame in a more space-saving manner.

[0015] The suspension attachment of the battery pack arrangement should be able to attach the battery pack arrangement relative to the frame in a suspended state. That is, when the battery pack arrangement is attached to the frame, the battery pack arrangement is suspended from the frame in a vertical orientation. Therefore, the battery pack arrangement hangs down from the frame. The suspension attachment can be provided in several different ways. For example, the suspension attachment includes a fastener. An example of a fastener is a bolt or a screw. Typically, the suspension attachment includes a plurality of spaced-apart attachment points, but this is strictly not required. In this way, the battery pack arrangement can be at least partially isolated from the frame, thereby avoiding or at least reducing the risk of torsional frame loads affecting the battery cell module. It is believed that a plurality of spaced-apart attachment points provide an improved ability to handle movement from the frame during vehicle operation. The number of attachment points can be distributed in any one of the longitudinal direction, the lateral direction, and the vertical direction. For example, the number of attachment points is three. Therefore, in an exemplary embodiment, the suspension attachment is a three-point suspension attachment with three attachment points. It should be noted that for other types of installations and vehicles, the number of suspension attachment points can be less than three or more than three. For example, the attachment points are provided with dampers having a damping material (e.g., a rubber material) to further enhance the ability to manipulate frame movement during vehicle operation. The dampers are typically arranged between fasteners of the suspension attachment and components of the battery pack. However, the dampers can be arranged in the suspension attachment in other ways. For example, the dampers can be arranged around fasteners of the suspension attachment, as well as between the suspension attachment and the frame. Thus, according to an exemplary embodiment, the suspension attachment includes a plurality of attachment points, wherein each of the attachment points includes a fastener and a damper.

[0016] According to an exemplary embodiment, at least one attachment point is arranged along the first longitudinal outer recess and at least one attachment point is arranged along the second longitudinal outer recess. In this way, the mechanical stability of the attachment to the frame is further improved, which will generally have a positive effect on the overall stability of the battery arrangement.

[0017] According to an exemplary embodiment, the battery pack arrangement further comprises a support structure, which is arranged to at least partially surround the battery pack. According to an exemplary embodiment, the support structure is configured to completely surround the battery pack.

[0018] For example, the support structure comprises a first part and a second part, wherein the first part is releasably connected to the second part. In this way, the flexibility of the arrangement is improved.

[0019] According to an exemplary embodiment, the suspension attachment is arranged on the support structure. Since the support structure surrounds the battery pack, the suspension attachment is arranged directly on the support structure and thus indirectly on the thermal management member. Alternatively, the suspension attachment can be arranged directly on the thermal management member. Alternatively, the suspension attachment can be arranged directly on any of the first and second battery modules. It is also conceivable that when the suspension attachment includes multiple attachment points, the multiple attachment points can be arranged on any of the components that make up the battery pack arrangement, for example, on top of the battery module and on top of the thermal management member.

[0020] It should also be noted that the battery pack may not be provided with a support structure, and therefore the suspension attachment is arranged on the battery pack at another part, such as directly or indirectly connected to the thermal management component.

[0021] Typically, the support structure of the battery pack arrangement is a separate part of the battery pack arrangement and surrounds the battery pack(s). Alternatively, the support structure may be an integral part of the battery pack arrangement. For example, the support structure may be part of any of the first and second battery modules.

[0022] According to an exemplary embodiment, the battery pack is a first battery pack and the battery pack arrangement further comprises a second battery pack. According to an exemplary embodiment, the battery pack arrangement may also comprise additional battery packs. Thus, the battery pack arrangement typically comprises a plurality of battery packs, but this is not strictly necessary.

[0023] Typically, each battery pack includes a housing for enclosing a first battery module and a second battery module. Typically, the housing includes a first portion and a second portion that are releasably connected to each other. An example advantage of the housing is to protect the battery modules from the external environment, such as from dust or moisture. Therefore, the housing can be made of a protective and waterproof material, such as a plastic material, a metal such as steel or stainless steel. It is also conceivable that the housing can enclose a single battery module. It is also conceivable that the housing can enclose a plurality of battery modules. It is also conceivable that the housing can enclose a complete battery pack.

[0024] The battery pack arrangement has an extension in the longitudinal direction and in the vertical direction. Therefore, the thermal management member is arranged between the first battery module and the second battery module in the longitudinal direction. Likewise, the opposite side of the thermal management member extends in the vertical direction, that is, the opposite side is a vertical opposite side. Therefore, the first battery module and the second battery module are arranged on opposite vertical sides of the thermal management member.

[0025] According to an exemplary embodiment, a first heat-conducting surface for adjusting the temperature of a first battery module and a second heat-conducting surface for adjusting the temperature of a second battery module correspond to opposite sides of a thermal management member, respectively. That is, the first heat-conducting surface is arranged on a first side of the thermal management member, and the second heat-conducting surface is arranged on a second side of the thermal management member. Typically, the first heat-conducting surface is a vertically oriented heat-conducting surface of the thermal management member, and the second heat-conducting surface is a vertically oriented heat-conducting surface of the thermal management member. Additionally or alternatively, the first side of the thermal management member is a vertically oriented side of the thermal management member, and the second side of the thermal management member is a vertically oriented opposite side of the thermal management member.

[0026] According to an exemplary embodiment, the thermal management component includes a fluid circuit configured to define a fluid passage for circulating a coolant therethrough. The fluid circuit has an inlet for liquid inflow and an outlet in fluid communication with the inlet for liquid outflow, the fluid passage being defined by at least a thermally conductive plate disposed on opposite sides of a channel, both plates being configured to be placed in thermal contact with at least one battery cell.

[0027] Typically, the thermal management component further includes a liquid coolant in the channel. An example of a suitable liquid is a water and ethylene glycol mixture. The coolant may also be an oil, or a combination of an oil and a water-based fluid. In another example, the coolant may be a fluid such as a gas. It should be noted that the thermal management plate component also includes a coolant. Furthermore, in this example, the coolant is contained in a fluid circuit corresponding to the channel. Thus, in the fluid circuit, the liquid coolant is transportable, typically with the aid of a pump unit. The liquid coolant may be used to remove heat from the battery pack and may also provide heating of the battery pack for rapid charging at low temperatures and / or for faster cold starts.

[0028] For example, the heat management member is a heat management plate member. In particular, the heat management plate member is a substantially flat plate member.

[0029] The thermal management component can be made of several different materials or combinations of materials. For example, the thermal management component is made of a conductive material, such as a conductive metal, such as aluminum, aluminum alloys, copper and / or gold. These types of materials provide sufficient levels of thermal conductivity while withstanding various stresses and loads. In addition, these types of materials are relatively machinable and can therefore be used as the material of the thermal management plate component.

[0030] According to an exemplary embodiment, the battery pack arrangement further includes a battery management control unit adapted to control the battery pack arrangement. For ease of reference, the battery management control unit may be simply referred to as a control unit. For example, the control unit is adapted to monitor the temperature of the battery modules of the battery pack. In addition, or alternatively, the control unit is adapted to set the temperature levels of the battery modules of the battery pack arrangement. For example, the control unit may be adapted to adjust the temperature level of the first temperature of the first battery module and the temperature level of the second temperature level of the second battery module. It should be noted that the control unit may include a microprocessor, a microcontroller, a programmable digital signal processor, or other programmable device. The control unit may also or alternatively include an application specific integrated circuit, a programmable gate array or programmable array logic, a programmable logic device, or a digital signal processor. In the case where the control unit includes a programmable device such as the above-mentioned microprocessor, microcontroller, or programmable digital signal processor, the processor may also include computer executable code that controls the operation of the programmable device.

[0031] It should be noted that the first battery module and the second battery module are typically fixedly attached to the thermal management thermally conductive component. The first battery module and the second battery module may be fixedly attached to the thermal management component, for example, by a fastening system or a plurality of fastening components (e.g., a plurality of bolts, screws, etc.). The first battery module and the second battery module are typically positioned adjacent to each other so that they can be connected to the thermal management component in an easy manner.

[0032] It should be noted that the battery pack arrangement may include one or several battery packs. Additionally or alternatively, each of the battery packs may include a plurality of battery modules as described herein. Additionally or alternatively, it is noteworthy that the battery pack arrangement may include different types of batteries. For example, any one of the battery modules in the battery pack arrangement is any one of a lithium-ion battery or a sodium-ion battery. Sodium-ion batteries typically include any type of sodium-ion battery or sodium ferrite battery. Therefore, the battery pack arrangement typically includes a group of battery packs. Furthermore, it is noteworthy that the battery packs and battery modules are typically so-called high-voltage battery packs. In the context here, the term "high voltage" refers to a battery pack of about 400-1000 volts (V). In addition, as used herein, the term "power" typically refers to electrical power.

[0033] According to a second aspect of the present invention, a vehicle frame arrangement is provided. The vehicle frame arrangement comprises a vehicle frame and a battery pack arrangement. The battery pack arrangement comprises a first battery module, a second battery module and a thermal management component, the first battery module having a first group of battery cells, the second battery module having a second group of battery cells, and the thermal management component being arranged between the first battery module and the second battery module. The thermal management component is configured to regulate the temperature of the first battery module and the second battery module, respectively. In addition, the vehicle frame arrangement comprises a suspension attachment for mounting the battery pack arrangement to the vehicle frame.

[0034] Typically, the battery arrangement comprises a suspension attachment for suspending the battery arrangement to the vehicle frame. However, it is also possible that the vehicle frame comprises a suspension attachment for suspending the battery arrangement to the vehicle frame.

[0035] The effects and features of the second aspect are largely similar to those described above in relation to the first aspect of the invention.

[0036] In particular, by providing a suspension attachment for suspending the battery pack arrangement to the vehicle frame, the vehicle frame arrangement according to the exemplary embodiment provides for the battery pack to be attached to the vehicle frame in a substantially vertical orientation relative to the vehicle frame. Thus, the exemplary embodiment provides for the attachment of the battery module and the thermal management member in a substantially vertical orientation relative to the vehicle frame.

[0037] Typically, when the battery pack arrangement is suspension mounted to the vehicle frame, a large portion of the battery pack arrangement is located below the vehicle frame when viewed in the vertical direction. For example, when the battery pack arrangement is suspension mounted to the vehicle frame, the battery pack arrangement is arranged to be lower than the vertical upper surface of the vehicle frame. Typically, the vertical upper region (e.g., the vertical upper surface of the battery pack arrangement) is suspension mounted to the vehicle frame such that the vertical upper surface is substantially parallel to the vehicle frame. In this way, a large portion of the battery pack arrangement is located below the vehicle frame when viewed in the vertical direction, thereby enabling the battery pack arrangement to be located in the vehicle in a space-saving manner.

[0038] Likewise, any of the exemplary embodiments and / or features as described above in relation to the first aspect of the invention may similarly be included in the frame arrangement according to the second aspect or any other exemplary embodiments of the second aspect.

[0039] According to an exemplary embodiment, the battery pack arrangement comprises a plurality of battery packs, wherein each of the plurality of battery packs is individually suspended and mounted to the vehicle frame. To this end, a modular battery pack arrangement may be provided, wherein one or more battery packs may be individually detachable from the vehicle frame.

[0040] According to an exemplary embodiment, the battery pack arrangement is shaped to accommodate a bottom portion of the vehicle frame. By way of example, the battery pack arrangement has a first longitudinal outer recess and a second longitudinal outer recess. The first longitudinal outer recess and the second longitudinal outer recess are arranged on the top of the battery pack arrangement. Thus, the top of the battery pack arrangement is the side of the battery pack arrangement facing the vehicle frame. That is, the first longitudinal outer recess and the second longitudinal outer recess are arranged on the side of the battery pack arrangement facing the vehicle frame.

[0041] Typically, when the battery pack arrangement is suspension mounted to the vehicle frame, the thermal management member is in a generally vertical orientation relative to the vehicle frame.

[0042] According to an exemplary embodiment, the suspension attachment comprises a plurality of spaced-apart attachment points, such that the battery pack arrangement can be attached to the frame via a plurality of positions. By way of example, the suspension attachment comprises three spaced-apart attachment points, such that the battery pack arrangement can be attached to the frame at three different positions. However, the attachment points may also be two or more, so as to enable the battery pack arrangement to be attached to the frame at least at more than two positions. According to an exemplary embodiment, the suspension attachment comprises a plurality of spaced-apart attachment points in the longitudinal direction and in the transverse direction, such that the battery pack arrangement can be attached to the frame at laterally opposite sides of the frame and at longitudinally different positions. According to an exemplary embodiment, the suspension attachment comprises a plurality of spaced-apart attachment points in the transverse direction, such that the battery pack arrangement can be attached to the frame at laterally opposite sides of the frame. According to an exemplary embodiment, the suspension attachment comprises a plurality of spaced-apart attachment points in the longitudinal direction, such that the battery pack arrangement can be attached to the frame at longitudinally different positions.

[0043] For example, the battery pack is arranged along the longitudinal direction of the frame and is arranged between the first ground engaging member and the second ground engaging member. An example of a ground engaging member is a wheel. Another example of a ground engaging member is a track. Typically, one or more motors are configured to drive at least a ground engaging member or a pair of ground engaging members. The (one or more) motors can be coupled to the ground engaging member in several different ways. In an exemplary embodiment, the (one or more) motors are coupled to a pair of ground engaging members via a transmission and a clutch. The transmission typically includes a plurality of gears, including a neutral gear. For example, the (one or more) motors are arranged to be decoupled from the ground engaging member via, for example, a clutch or a neutral gear, thereby allowing the (one or more) motors to rotate while the vehicle is stationary.

[0044] According to an exemplary embodiment, the frame arrangement further comprises a support structure for the first battery pack arrangement and the second battery pack arrangement. In the exemplary embodiment, the suspension attachment is typically arranged on the support structure, but this is not strictly necessary.

[0045] According to an exemplary embodiment, the vehicle frame arrangement comprises a plurality of battery packs which can be connected to each other. Additionally or alternatively, the vehicle frame arrangement comprises a plurality of battery pack arrangements which can be connected to each other.

[0046] According to an exemplary embodiment, a first battery module and a second battery module are arranged on opposite sides of a thermal management component. The thermal management component includes a first thermally conductive surface for regulating a temperature of the first battery module and a second thermally conductive surface for regulating a temperature of the second battery module.

[0047] The frame of the vehicle generally includes a lower frame portion. In an exemplary embodiment of this type, the battery pack arrangement is generally connected to the lower frame portion of the frame. However, the battery pack arrangement can also be connected to another portion of the frame, such as a side portion, an upper portion, or a combination thereof.

[0048] According to a third aspect of the present invention, a vehicle is provided, comprising a battery pack arrangement and / or a frame arrangement, wherein the battery pack arrangement is according to any one of the exemplary embodiments and / or features described above with respect to the first aspect of the present invention, and the frame arrangement is according to any one of the exemplary embodiments and / or features described above with respect to the second aspect of the present invention.

[0049] The effects and features of the third aspect are largely similar to those described above in relation to the first aspect of the invention.

[0050] In addition, the vehicle may include a chassis. In addition, the vehicle typically includes an electric propulsion system having a battery pack arrangement. The vehicle may be an electric, hybrid or plug-in hybrid vehicle. Therefore, the vehicle may be a fully electric vehicle or a partially electric (i.e., hybrid) vehicle. The vehicle typically includes at least one motor, but may also include additional motors. (One or more) motors are configured to provide propulsion to the vehicle. Generally, as used herein, the term "electric propulsion system" generally refers to a vehicle electrical component for providing energy (e.g., traction energy) and for storing energy (delivering and receiving energy). In other words, an electric propulsion system refers to a system configured to provide propulsion to the vehicle by converting electrical energy into mechanical energy, the electrical energy being provided by an energy storage system such as a battery pack arrangement. In addition to the electrical components as described above, the electric propulsion system may include additional components, such as (one or more) cables, (one or more) sensors, a control unit, (one or more) battery management units, etc. The electric propulsion system is particularly configured to deliver and receive energy to provide propulsion to the vehicle, and is also used to perform various vehicle operations of the vehicle.

[0061] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness. Throughout the specification, like reference numerals represent like elements. The drawings are not necessarily drawn to scale, and certain features may be enlarged to better illustrate and explain the exemplary embodiments of the present invention.

[0062] Now referring to the drawings, for example Figure 1 , depicts a vehicle 10 in the form of a truck, particularly an electric heavy-duty truck. The electric truck is a fully electric truck. Vehicles of this type typically include an electric propulsion system (not shown) for providing propulsion to the electric truck. In addition to providing propulsion to the vehicle, the electric propulsion system or portions of the system may manage other electronic functions of the vehicle. The electric propulsion system typically includes an energy storage system, such as a battery pack arrangement 40, such as in Figure 2a and 2b The battery arrangement is configured to power one or more electrical components such as an electric motor. The vehicle may further include a battery management unit (not shown) configured to control and monitor the battery arrangement.

[0063] In addition, the electric propulsion system typically includes one or more motors (not shown). The motor is configured to drive a pair of ground engaging members, such as 92 and / or 94. In this example, the ground engaging members are provided in the form of wheels. Optionally, the electric propulsion system includes a transmission (not shown) for transmitting rotational motion from the motor to a propulsion shaft (sometimes represented as a driven shaft). The propulsion shaft connects the transmission to the pair of wheels. In addition, although not shown, the motor is typically coupled to the transmission via a clutch. The motor can also be disconnected from the wheel by engaging the neutral gear of the transmission.

[0064] Furthermore, the vehicle includes a frame 20. In this example, the frame 20 and the battery pack arrangement form a frame arrangement 30, as will be described below with respect to Figures 2a to 6 Further described.

[0065] As shown in Figure 2 to Figure 6 As clearly shown in Figure 2a , the frame arrangement 30 extends at least along a longitudinal direction L, a vertical direction V and a transverse direction T. The longitudinal direction L of the frame arrangement is substantially parallel to the intended direction of travel of the vehicle 10. Therefore, the longitudinal direction L of the frame arrangement is substantially consistent with the longitudinal direction of the vehicle 10. In addition, the transverse direction T is substantially perpendicular to each of the vertical direction V and the longitudinal direction L. That is, the transverse direction T is parallel to the overall extension of the frame 20. These directions are intended to be read relative to the vehicle and should not be interpreted as being dependent on the vehicle orientation. As is apparent from the above, the frame 20 also extends at least along a longitudinal direction L, a vertical direction V and a transverse direction T, and similarly, the battery pack arrangement 40 extends at least along a longitudinal direction L, a vertical direction V and a transverse direction T. It should be noted that the terms top, above, up, upwards, below, below, below, downwards, bottom, lateral and side and any other similar terms are with reference to, for example Figure 2a , Figure 2b and Figures 3 to 6The battery pack arrangement shown is used relative to the position of the vehicle frame. It should also be understood that the examples shown in the drawings and described in the following specification are merely exemplary embodiments. Therefore, the dimensions and other physical characteristics related to the embodiments disclosed herein should not be considered limiting unless the appended claims expressly state otherwise.

[0066] Turning now again to the vehicle frame arrangement 30 including the vehicle frame 20 and the battery pack arrangement 40, Figure 2a An exemplary embodiment is depicted in FIG. Figure 2a is a perspective view of a frame arrangement according to an exemplary embodiment of the present invention. Figure 2a The frame arrangement in can be combined with the above Figure 1 In this example, the frame arrangement 30 includes the frame 20 and a battery pack arrangement 40 including a plurality of battery packs 43 , 47 , 49 distributed along the longitudinal direction L of the frame 30 .

[0067] In addition, the battery pack arrangement 40 further includes a suspension attachment 80 for suspending the battery pack arrangement to the vehicle frame. The suspension attachment is configured to arrange the battery pack arrangement in a substantially vertical orientation. That is, the vertical direction of the battery pack arrangement generally coincides with the vertical direction of the vehicle frame and the vertical direction of the vehicle. Figure 2a As shown in FIG, the battery pack arrangement 40 includes a suspension attachment 80 having a plurality of attachment points for suspension mounting the battery pack arrangement to the frame at a plurality of points along the frame portion 20 a and the frame portion 20 b. The suspension attachment points are distributed along the frame both laterally and longitudinally so that the battery pack arrangement can be connected to the frame at laterally opposite sides 20 a and 20 b.

[0068] In addition, Figure 2a , the battery pack arrangement 40 is arranged along the longitudinal direction L of the vehicle frame and is arranged between the first ground engaging member 92 and the second ground engaging member 94, in other words, the battery pack arrangement is arranged within the wheelbase of the vehicle.

[0069] Furthermore, the frame arrangement here, and therefore the battery pack arrangement, comprises a plurality of battery packs 43, 47 and 49. In this example, the plurality of battery packs are also individually suspended and mounted to the frame 20, for which purpose a modular battery pack arrangement can be provided in which one or more battery packs can be individually detached from the frame. In addition or alternatively, the battery packs can be interconnected with each other. In this way, the battery packs are battery packs that can be interconnected to form interconnected battery pack arrangements, which are connected to the frame 20. For example, the battery pack arrangement comprises three battery packs. The number of battery packs in the battery pack arrangement varies depending on the vehicle type and the type of installation, among other things. Figure 2a Further features and exemplary embodiments of the battery pack arrangement in Figures 3 to 6 Give a description.

[0070] Reference now Figure 2b , a further exemplary embodiment of a frame arrangement according to the invention is described. Figure 2b is a perspective view of a vehicle frame arrangement showing portions of a battery pack arrangement according to an exemplary embodiment of the present invention in partial cross-section. Figure 2b As shown in , the battery pack arrangement 40 here comprises a single battery pack 43. The battery pack arrangement 40 is suspended mounted to the frame 20, for example, by means of a suspension attachment 80 having attachment points 45a and 45b, wherein the attachment points 45a and 45b connect the battery pack arrangement 40 to the frame at laterally opposite sides along the frame parts 20a and 20b, respectively. In other words, a frame arrangement 30 is provided comprising the frame 20 and the battery pack arrangement 40. It should be noted that this example of the battery pack arrangement may also include a suspension attachment having three attachment points, as described with respect to Figure 2a as described in the examples.

[0071] In addition, if Figure 2b As shown in , the battery pack arrangement 40 having a battery pack 43 here includes a first battery module 64 having a first group of battery cells and a second battery module 67 having a second group of battery cells. The battery pack 43 also includes a thermal management member in the form of a thermal management plate member 70 arranged between the first battery module 64 and the second battery module 67, respectively. The thermal management plate member is configured to regulate the temperature of the first battery module 64 and the second battery module 67, respectively. The thermal management plate member is thermally conductive. In addition, as shown in FIG. Figure 2b As shown in , when the battery pack arrangement 40 is suspension mounted to the vehicle frame, the thermal management plate member 70 is in a generally vertical orientation relative to the vehicle frame 20. Thus, the vertical direction of the thermal management plate member generally coincides with the vertical direction of the vehicle frame and also the vertical direction of the vehicle.

[0072] The battery pack, in particular the battery module, may be sensitive to temperature changes and often needs to be operated at an appropriate temperature or within an appropriate temperature range. For example, each of the battery modules in the battery module is a lithium-ion battery. In addition, each of the battery modules in the battery module includes a plurality of battery cells. The number of battery cells in each battery module and the total number of battery cells vary depending on the vehicle type and the installation type, etc.

[0073] like Figure 2bAs further shown in FIG. 5 , the first battery module 64 and the second battery module 67 are arranged on opposite sides 72, 74 of the thermal management plate member 70. The opposite sides 72, 74 are vertically opposite sides of the thermal management plate member. The thermal management plate member has a first thermally conductive surface 73 for regulating the temperature of the first battery module and a second thermally conductive surface 75 for regulating the temperature of the second battery module. The battery cells in each of the battery modules are typically connected in series. However, the battery cells may be connected in series or in parallel depending on the desired voltage level output from the battery module.

[0074] As described above, the battery pack arrangement 40 includes the suspension attachment 80 for suspending the battery pack arrangement 40 to the vehicle frame 20. In particular, as shown in FIG. Figure 2b as well as Figure 3 and Figure 4 As shown in FIG. 8 , the suspension attachment 80 is configured to attach the battery pack arrangement to the vehicle frame 20 in a generally vertical orientation. Figure 3 yes Figure 2b FIG. 4 is a top view of a battery pack arrangement 40 in which the battery pack arrangement is suspended from the vehicle frame 20, for example, at portions 20a and 20b. Referring now to FIG. Figure 4 , which is Figure 3 The front view of the battery pack arrangement in FIG. 4 shows that the battery pack arrangement 40 is arranged to be lower than the vertical upper surface V of the frame 20. V Typically, the vertical upper area (eg, the vertical upper surface V of the battery pack arrangement 40) B ) is suspended and mounted to the frame so that the vertical upper surface V V Substantially parallel to the frame 20, for example, parallel to the horizontal center plane V of the frame 20 C .

[0075] Usually, if Figure 4 As shown in FIG, when the battery pack arrangement 40 is suspended and mounted to the vehicle frame 20, most of the battery pack arrangement is located below the vehicle frame 20 when viewed in the vertical direction V. For example, most of the battery pack arrangement is located below the vehicle frame 20, so that most of the battery pack arrangement is located below the vertical center plane V of the vehicle frame 20. C , such as from Figure 4 Can be seen.

[0076] In this example, the battery pack arrangement is arranged along the longitudinal direction of the frame and is arranged between the first ground engaging member 92 and the second ground engaging member 94. In other words, the battery pack arrangement is arranged within the wheelbase of the frame (ie, within the wheelbase of the vehicle).

[0077] As above about Figure 2a As stated, about Figure 2b , Figure 3 and Figure 4The exemplary embodiment also includes a suspension attachment 80 that includes a plurality of laterally spaced apart attachment points 45a, 45b, and optionally 45c. The plurality of attachment points enables the battery pack arrangement to be connected to the vehicle frame at laterally opposite sides 20a and 20b. Figure 5b As shown in , the spaced apart attachment points 45a, 45b and 45c are also spaced apart in the longitudinal direction L. The suspension attachment here comprises a damper (not shown). In particular, each of the attachment points comprises a damper. For example, each of the attachment points comprises one or more bolts as fasteners and a damper. Figure 5b In the embodiment, each attachment point has four fasteners and a damper arranged between the fasteners and the battery pack arrangement, thereby forming the suspension attachment.

[0078] It should be noted that Figure 3 and Figure 4 The described exemplary embodiments can be equally applied to Figure 2a Exemplary embodiments are described.

[0079] Now go to Figure 4 , Figure 5a and Figure 5b The battery pack arrangement 40 is generally shaped to receive the bottom portion 20 a , 20 b of the vehicle frame 20 . Figure 5a is a perspective view of a battery pack arrangement according to an exemplary embodiment of the present invention, wherein the battery pack arrangement includes a first battery pack 43 and a second battery pack 47, and Figure 5b yes Figure 5a Exploded view of the battery pack arrangement in the . Figure 5a and Figure 5b The described features and examples apply analogously to Figure 2a As long as there is no contradiction or the contrary is not explicitly mentioned, the battery pack arrangement is provided. For example, the battery pack arrangement has a first longitudinal outer recess 31 and a second longitudinal outer recess 32. The first longitudinal outer recess 31 and the second longitudinal outer recess 32 are configured to receive the bottom portion 20a and the bottom portion 20b of the frame, respectively. Figure 5b As shown in FIG. 1 , each of the battery packs 43, 47 includes a first longitudinal outer recess 31 for accommodating a portion of the vehicle frame and a second longitudinal outer recess 32 for accommodating another portion of the vehicle frame. When the suspension attachment includes a plurality of spaced apart attachment points, for example Figure 5a and Figure 5b The three-point suspension attachment 45 in FIG. 4 , namely three attachment points 45a, 45b and 45c, one of the attachment points 45a is arranged along the first longitudinal outer recess 31, while the other attachment points 45b, 45c are arranged along the second longitudinal outer recess 32. However, these attachment points can be distributed in other ways.

[0080] Optionally, the battery pack arrangement further comprises a support structure 88 for supporting the battery pack, such as for example Figure 5a and Figure 5b As shown in Figure 5a and Figure 5b As shown in , the support structure 88 is configured to accommodate the first battery pack 43 and the second battery pack 47. Moreover, in this example, the suspension attachment 80 is arranged on the support structure 88. The support structure 88 is therefore arranged to at least partially surround the battery packs 43 and 47. In this example, the support structure 88 includes a first portion 61 and a second portion 68, wherein the first portion 61 is releasably connected to the second portion 68. For example, the first portion and the second portion are a first bracket and a second bracket. The first portion and the second portion can be releasably connected by a fastening system (e.g., a plurality of bolts). In addition or alternatively, the first portion and the second portion can be releasably connected by opposite lateral sides 42. The lateral side can be provided in the form of a side impact protection member to protect the battery pack and the battery module from side impact during the use of the battery pack arrangement in the vehicle.

[0081] As mentioned above, in this example, the suspension attachment is arranged on the support structure. Furthermore, in this example, the suspension attachment is arranged on one of the tops 37 of the support structure. Figure 5b As shown in , the support structure here also includes a set of bottoms 38. The bottom 38 can be arranged under the battery pack as a protective plate to protect the battery from impact and debris. Thus, the support structure surrounds the battery modules of the battery pack. It should be noted that the battery pack can be without a support structure, and the suspension attachment can be arranged on the battery pack at another part, such as directly or indirectly connected to the thermal management plate member 70.

[0082] It should be noted that although e.g. Figure 5a and Figure 5b The support structure of the battery pack arrangement shown in is a separate part of the arrangement connected to the battery pack, but the support structure may similarly be an integral part of the arrangement. For example, the support structure may be part of any one of the first battery module and the second battery module.

[0083] Figure 6 is an exploded view of some features of a battery pack according to a battery pack arrangement of an exemplary embodiment of the present invention. For ease of reference, Figure 6 The battery pack in this case is the battery pack 43, which can form a battery pack arrangement together with a suspension attachment (not shown), such as Figure 2b or together with additional battery packs and suspension attachments to form a battery pack arrangement, such as Figure 2aAs shown in . The battery pack 43 includes a first battery module 64 having a first group of battery cells 84 and a second battery module 67 having a second group of battery cells 87. The thermal management plate member 70 is arranged between them, as seen in the longitudinal direction L. Therefore, the first battery module 64 and the second battery module 67 are arranged on opposite sides 72, 74 of the thermal management plate member 70. The first battery module 64 and the second battery module 67 are vertically mounted on both sides of the thermal management plate member. As described above, the thermal management plate member includes a first thermally conductive surface 73 for adjusting the temperature of the first battery module and a second thermally conductive surface 75 for adjusting the temperature of the second battery module. In addition, the thermal management plate member is generally oriented to the battery modules 64 and 67 in a vertical orientation. That is, the first thermally conductive surface 73 is a vertically oriented surface of the thermal management plate member, and the second thermally conductive surface 75 is a vertically oriented surface of the thermal management plate member. In addition, the first side of the thermal management plate member is the vertically oriented side of the thermal management plate member, and the second side of the thermal management plate member is the opposite side of the vertical orientation of the thermal management plate member.

[0084] Therefore, if Figure 6 As shown in , a first heat-conducting surface 73 for regulating the temperature of the first battery module 64 and a second heat-conducting surface 75 for regulating the temperature of the second battery module 67 correspond to opposite sides of the thermal management plate member. Moreover, the thermal management plate member includes a fluid circuit 60, which is configured to define a fluid passage for circulating a coolant therethrough. In addition, the battery pack here includes a thermal management interface 62 having input and output connections for a hose. In other words, the fluid circuit has an inlet (not shown) for liquid inflow and an outlet (not shown) for liquid outflow that is fluidly connected to the inlet. The fluid passage is defined by at least a heat-conducting plate surface disposed on opposite sides of the channel, and both plate surfaces are configured to be placed in thermal contact with a battery module including a battery cell. In addition, the battery module is connected to the thermal management plate member by a fastening member, in this example, a plurality of screws and nuts 63 that are arranged on both sides and pass through the battery module and fastened together. As Figure 6 As shown in , the thermal management plate member is a substantially flat plate member. In this example, the thermal management plate member is made of a conductive material such as aluminum. The thermal management plate member 70 has a channel that covers as large an area as possible of the area occupied by the bottom of the battery cell. The first side 72 of the thermal management plate member and the second side 74 of the thermal management plate member are connected to each other to provide mechanical rigidity to the battery pack. In addition, the inner surfaces of the first side 72 and the second side 74 may each include silicone and a rubber ring (not shown) to seal between the sides 72 and 74 when formed into the thermal management plate member. In other words, the thermal management plate member can be formed as a unit having opposite vertical sides 72, 74, or as a two-part thermal management plate member having opposite vertical sides 72, 74 bonded to each other.

[0085] For example, the thermal management plate assembly 70 further includes a liquid coolant in the channel, thereby forming a fluid circuit. The coolant in the fluid circuit is typically a liquid fluid medium. Therefore, in the fluid circuit, the liquid coolant is transportable, typically with the aid of a pump unit (not shown). The coolant can be used to remove heat from the battery pack and also provide heating of the battery pack for fast charging at low temperatures and / or for faster cold starts. Therefore, the term "fluid" in the context of these exemplary embodiments refers to a liquid fluid. However, the type of coolant may vary depending on the type of vehicle and the type of installation. Typically, the coolant is water-based. For example, the coolant is water-based, to which ethylene glycol is added to prevent freezing and other additives for limiting corrosion, erosion, cavitation, etc.

[0086] Returning to the battery modules again, each of the battery modules 64, 67 includes a plurality of battery cells 84, 87, respectively. The battery cells are arranged in a state in which the battery cells are connected in series to each other. The battery modules and the battery cells are electrically connected to each other, and the thermal management plate member is connected to the battery modules, so that the coolant in the thermal management plate member is allowed to regulate the temperature of each of the battery modules.

[0087] Furthermore, to further improve the contact between the battery modules and the heat management plate member, so-called gap fillers may be arranged between the sides of the heat management plate member and the first and second battery modules, respectively. The gap fillers may be in the form of acrylic material or film.

[0088] In order to protect the battery cells from external contamination, dust, dirt and moisture, in this example, the battery pack 43 is provided with a housing 46, such as Figure 6 As shown in . The housing 46 surrounds the first battery module 64 and the second battery module 67. The housing is typically a two-part housing having a first part 41 and a second part 48. The housing also surrounds the thermal management plate component 70. Moreover, the housing also accommodates any other components of the first battery module and the second battery module. The housing is made of, for example, a plastic material or a metal (such as steel, stainless steel, etc.). Typically, the material of the housing should be able to resist moisture and is therefore essentially made of a waterproof material. The components of the housing can be connected by glue, bolts or any other fasteners. In addition or alternatively, one of the components of the housing may include a flange 61a for forming a strong sealing method for the cooling plate (thermal management plate component), such as Figure 6As shown in . Electrical insulation and thermal insulation may also cover the internal components of the housing. In addition, the battery pack typically includes an electrical box 69 with fuses and the like. The electrical box can be arranged inside the battery module or outside the battery module. The electrical box 69 (electrical connector) and the thermal connector 62 can be positioned along the lateral side of the battery pack arrangement and are therefore typically arranged on the lateral side of the vehicle. In this way, connector access for service and the like is provided.

[0089] It should be noted that Figures 3 to 6 The exemplary embodiments of the battery pack described are also applicable to Figure 2a Therefore, as described above, as described above Figure 1 The electric vehicle thus comprises a frame arrangement comprising a frame and a battery pack arrangement, the battery pack arrangement being arranged according to Figure 2a to Figure 2b Combination Figures 3 to 6 Any of the exemplary embodiments described.

[0090] The battery pack arrangement may also include a control unit (not shown). The control unit is connectable to the battery pack arrangement. That is, the control unit is adapted to control temperature regulation of the battery modules. For example, the control unit is adapted to set the levels of the first and second temperatures, as described above. In addition or alternatively, the control unit may be part of another system in the vehicle. For example, the vehicle includes a control unit to perform various operating steps for controlling the temperature of the battery pack arrangement. In other designs of systems and vehicles, the control unit may be arranged at another remote location of the vehicle.

[0091] It should be understood that the present invention is not limited to the embodiments described above and shown in the drawings; rather, those skilled in the art will recognize that many changes and modifications are possible within the scope of the appended claims.
