An HVDB may be a box that monitors and controls the voltage supplied from a battery pack to various loads of a vehicle or building. The HVDB may be connected, for example, via an interface to battery subassemblies, battery modules, or battery cells of a battery pack and switch power for high voltage loads (e.g., electric motors, drive units, heating, ventilation, or air conditioning systems) or low voltage loads (interior lighting, monitors, electronics). A battery pack of a vehicle, such as an electric vehicle, may have a variety of configurations. For example, the battery packs may have different mechanical or structural architectures (e.g., different shapes, sizes, or shape factors). Moreover, the battery packs may include batteries or battery modules having various chemical compositions (e.g., lithium iron phosphate (LFP), nickel-based cathode chemistries, high nickel chemical compositions, nickel manganese cobalt (NMC) chemical compositions generally comprising greater than 33 wt %, or high nickel chemical compositions having greater than 80 wt % nickel, nickel cobalt aluminum (NCA) chemical compositions, nickel cobalt manganese aluminum (NCMA) chemical compositions, lithium manganese iron phosphate (LMFP) chemical compositions, overlithiated oxide (OLO) chemical compositions, Lithium Cobalt Oxide (LCO) chemical compositions, lead acid chemical compositions, nickel cadmium chemical compositions, nickel metal hydride chemical compositions, zinc carbon chemical compositions, or any other type of chemical composition).Moreover, the battery packs may include different cell shape factors (e.g., cylindrical cells, fixed housing prismatic cells, pouch cells, etc.) or different battery module designs. The HVDB for these battery packs may be specifically designed for the structural and chemical configuration of the respective battery pack. Therefore, a separate HVDB can be designed and manufactured for each battery pack type, which can require a considerable amount of development and manufacturing resources.Moreover, the HVDB may include components that a technician must be able to service, replace, or repair. However, because the HVDB may be integrated within the battery pack (e.g., within a housing of the battery pack), the service technician may not be able to access the components of the HVDB without opening the entire battery pack. An HVDB may be disposed within the housing of a battery pack. In some cases, the HVDB is coupled to a lid of the battery pack and is located between the battery modules of the battery pack and the lid of the battery pack. Thus, for access and maintenance of the HVDB, the entire battery pack may need to be removed from the vehicle and opened.To solve these and other technical problems, the present solution may provide a package independent HVDB. The HVDB may be coupled to an exterior of the battery pack such that the battery pack and the HVDB may be separately designed and manufactured. Although the battery packs may be designed with a variety of structural or chemical configurations, the battery packs may be designed to include the same connecting components for the HVDB for connection and to be able to place electrical and thermal connectors at a common location in the battery pack. Therefore, the HVDB may be coupled and connected to each battery pack regardless of the structural or chemical configuration of the pack. This can reduce the number of different types or configurations of HVDBs that need to be designed and manufactured. This can further reduce the number of HVDB types that a service technician must stock to replace an HVDB. This can increase the speed at which a technician can perform maintenance on an HVDB of an electric vehicle.The HVDB may include a housing. The housing may be coupled to an exterior of the housing of the battery pack. For example, the battery pack housing may include an interface or opening in a housing wall through which electrical or thermal connections may be made between the battery pack and the HVDB. The housing of the HVDB may be coupled to the outside of the housing of the battery pack via the opening. At least one electrical or thermal connector of the HVDB may be interfaced to the battery pack through the opening in the wall of the battery housing. For example, the HVDB may make electrical connections with busbars, wires, or other electrical connections. The HVDB may receive power from the batteries of the battery pack via the electrical connections or provide power to the batteries of the battery pack to charge the batteries via the electrical connections.Moreover, a bottom surface of the HVDB may include a removable plate. The housing of the HVDB has a plate on the bottom side of the housing. The removable panel may be coupled to the lower ends of the side walls or sides of the housing. The removable plate may be removed or separated from the housing. A technician may remove the panel during servicing of the electric vehicle to access and service or replace the components of the HVDB from the bottom of the housing (e.g., a battery management system, fuses, contactors, connectors, etc.). When a technician is under a vehicle (e.g., when the vehicle is lifted from the ground with a lift or jack), he may access the removable panel, disconnect the panel from the housing of the HVDB, and service the components of the HVDB. Therefore, to maintain the HVDB, the battery pack does not need to be removed or opened from the vehicle.Referring to FIG. 1, an example of an expanded view of a battery pack 100 and an HVDB 175 is shown, among other things. The battery pack 100 may propel an electric, hybrid, or internal combustion engine vehicle. The battery pack 100 may provide power to a business or residential building to operate facilities, devices, or systems of the building. The battery pack 100 may include a housing 105. The housing 105 may be or may include a frame, a case, a device, or a housing to partially or fully enclose components, devices, or systems of the battery pack 100. The housing 105 may be made of or include aluminum, steel, or carbon fiber. The housing 105 may be coupled, attached, attached to, or attached to a frame of a vehicle, building wall, or building floor. The housing 105 may include elements 125, 130, 135, and 140 (e.g., lateral sides, walls, or surfaces). The housing 105 may include inner surfaces and outer surfaces. The housing 105 may include a top or lid 145 and a bottom 120. The battery pack 100 may include at least one interface 165 to couple the lid 145 to the housing 105. The battery pack 100 may include at least one interface 170 to couple the lid 145 to an electric vehicle.The lateral sides 125, 130, 135, and 140 may extend from the bottom 120 to the top 145. The lateral sides 125, 130, 135, and 140 may define a space for receiving and protecting the battery modules 150. A first lateral side 125 and a second lateral side 135 may be parallel to each other. A third lateral side 130 and a fourth lateral side 140 may be parallel to each other. The first lateral side 125 and the second lateral side 135 may be perpendicular to the third lateral side 130 and the fourth lateral side 140, respectively. The lateral sides 125- 140 may surround an outer perimeter or outer perimeter of the housing 105. The lateral sides 125- 140 and the bottom 120 may be integrally formed or coupled, attached, welded, or joined. The top surface 145 may be removable from the housing 105.The battery pack 100 may include battery modules 150 (or a battery or groups of battery cells). The battery modules 150 may each include a group of batteries, battery cells, or other charge storage devices. The battery modules 150 may include thermal components (e.g., cooling plates) to cool the batteries with a liquid, such as a coolant. The battery pack 100 may include at least one thermal component 155. The thermal component 155 may be or include thermal leads, cooling plates, heat pipes, or tubes. The thermal lines may direct coolant to cooling plates that transport the heat generated at the battery modules 150 away from the battery modules and out of the battery pack 100.The battery pack 100 may include an electrical component 160. The electrical component 160 may include any active electrical components (e.g., sensors, circuits, etc.) that may output a signal (e.g., input signals, voltages, currents, and temperature) in response to an input, as well as any passive electrical components (e.g., cables and wires) that may communicate, transmit, or sense voltages, currents, temperatures, etc. For example, the electrical component 160 may be or include a wire harness, wires, cables, bus bars, a fuse, a pyro, a battery management system, a switching module or other electrical conductors, etc. The electrical component 160 may include high and low voltage electrical terminals. For example, the electrical component 160 may be connected to sensors that monitor high voltage operation of the battery pack 100. The measurements may be or include temperature measurements by a temperature sensor, voltage measurements by a voltage sensor, current measurements by a current sensor, or gas measurements by a gas sensor. The signals may indicate states of the battery modules 150, e.g., temperature, voltage, current, state of charge, fault status, etc.A device, apparatus, module, system, or HVDB 175 may be coupled to the housing 105. The HVDB 175 may be coupled to the lateral side 140 of the housing 105. The side side 140 of the housing may be a front side of the battery pack 100 such that when an electric vehicle (e.g., as described in FIG. 11 ) is powered or is driving forward, the side side 140 is forward. The HVDB 175 may be coupled to an exterior of the housing 105, e.g., to a side opposite the cavity of the housing 105 in which the battery modules 150 are disposed. The lateral side 140 may include an interface 180. The interface 180 may be or include an opening. The opening may be or include a square shaped, a circular shaped, a rectangular shaped, or an opening of any other suitable shape. The HVDB 175 may be coupled to the lateral side 140 of the housing 105 on an exterior of the housing 105. The HVDB 175 may be coupled to the interface 180. For example, a housing 185 of the HVDB 175 may be coupled to or above the interface 180 such that at least one electrical or thermal connection may be established between the battery pack 100 and the HVDB 175. A side of the housing 185 of the HVDB 175 may be disposed on the lateral side 140 of the housing 105. At least one nut, rivet, adhesive, weld, or connector may connect the lateral side 140 to the housing 185 of the HVDB 175. For example, at least one of the lateral sides 140 or the housing 185 may include openings or holes into which screws may be inserted to couple the lateral sides 140 to the housing 185.The HVDB 175 may include electrical or thermal components disposed at least partially within the housing 185. For example, a battery management system 190, a battery monitor 195, or a switching module 197 may be at least partially or fully disposed within the housing 185. The electrical components may interface or be connected to the battery via at least one electrical connector of the HVDB 175. The electrical connector may be connected to an electrical connector of the battery pack 100 through the opening 180 in the lateral side 140 of the housing 105. For example, the battery management system 190, the battery monitor 195, or the switching module 197 may be electrically coupled to an electrical connector of the HVDB 175. The electrical connector of the HVDB 175 may be interfaced or coupled to an electrical connector of the battery pack 100. The HVDB may be responsible for distributing battery power within an all-wheel-drive (AWD) or single-axle drive configuration of the vehicle that ultimately determines the drive configuration of the vehicle. In addition, the HVDB may provide battery power to auxiliary systems such as heaters, climate control pumps, etc.For example, the switch module 197 may be electrically coupled to the bus bars 160 of the battery pack 100. For example, a first electrical connector of the HVDB 175 may be coupled to a first bus bar of a first polarity (e.g., positive), while a second electrical connector of the HVDB 175 may be coupled to a second bus bar of a second polarity (e.g., negative). The bus bars of the battery pack 100 may be electrically coupled to the battery modules 150. The switching module 197 may control the transmission or transfer of current between a vehicle component (e.g., a motor, a heater, an air conditioning pump, an electrical device, a headlamp, an interior lamp, a charging component, a charging port, etc.) and the battery modules 150. The controller may include directing or switching current or monitoring voltage or temperature. For example, the switching module 197 may include switches, contactors, fuses, or other components that may control power transfer. The switching module 197 may actuate contactors to cause the battery modules 150 to provide power to the component of the vehicle via the electrical connection systems through the opening 180 in the side wall 140 of the housing 105. The switching module 197 may actuate contactors to cause the battery modules 150 to provide current from a component of the vehicle (e.g., charging connector or motor in a generative braking mode) to the battery modules 150 via the electrical connections through the opening 180 in the sidewall 140 of the housing 105 to charge the battery modules 150.The battery monitor 195 may be electrically coupled to the wire harness 160 of the battery pack 100. The battery monitor 195 may be coupled to at least one electrical terminal of the HVDB 175, which may be electrically coupled to at least one electrical terminal of the battery pack 100 via the interface 180. The battery monitor 195 may receive electrical signals, data packets, measurements, sensor readings, or other data from sensors of the battery pack 100. The signals may indicate characteristics of the battery modules 150 such as temperature, voltage, state of charge, and fault status. The battery monitor 195 may include at least one switch or multiplexer to route the signals received from the battery pack 100 to the battery management system 190. The battery monitor 195 may be electrically coupled to the battery management system 190 and provide the signals to the battery management system 190.The battery management system 190 may receive the signals from the battery monitor 195. The battery management system 190 may generate, determine, calculate, or identify characteristics (e.g., battery temperature, state of charge of the battery, battery voltage, fault status, discharge rate, time to discharge, number of total charges, remaining lifetime) of the battery cells 150 based on the signals. The battery management system 190 may generate and store values for the characteristics of the battery modules 150. The battery management system 190 may be electrically coupled to the switching module 197. The battery management system 190 may control contactors of the switching module 197 to cause the switching module 197 to provide power from the battery modules 150 to a load of a vehicle (e.g., motor, heater, device). The battery management system 190 may control contactors of the switching module 197 to cause the switching module 197 to provide power from a charging port of the vehicle to the battery modules 150 to charge the battery modules 150.Referring now to FIG. 2, the HVDB 175 is shown coupled to battery packs of different types, among other things. In FIG. 2, both a first battery pack 100 and a second battery pack 205 are coupled to the HVDB 175. The HVDB 175 may be packet independent. For example, the HVDB 175 may be configured to interface via a mechanical connector or interface of the HVDB 175 with multiple different types of battery packs 100. For example, the thermal or electrical connectors of the HVDB 175 may be configured to interface with and connect to a plurality of different types of battery packs 100. Moreover, the package independent HVDB 175 may electrically couple and control multiple different types of battery packs 100, e.g., battery packs having different package chemical compositions, different number of package cells, different package cell shape factors, or different package dimensions. Controlling the battery packs 100 may include operating the battery packs 100. For example, control of the battery packs 100 may include causing the battery packs 100 to provide current to a charge, a load based on the current received from a charge source, a load based on the current generated by a motor during regenerative braking. Control of the battery packs 100 may include communicating with the battery packs 100. For example, the controller may include receiving sensor signals such as a voltage measurement, a current measurement, a gas measurement. Control of the battery packs 100 may include determining, assessing, or detecting a state of the battery packs 100, e.g., determining a state of charge of the battery packs 100, determining an output voltage of the battery packs 100, determining a range of the battery packs 100.The HVDB 175 may be configured to be coupled to multiple battery packs of different configurations, e.g., the first battery pack 100 and the second battery pack 205. The first battery pack 100 and the second battery pack 205 may have different battery cell chemical compositions (e.g., lithium iron phosphate (LFP), nickel-based cathode chemistries, high nickel chemical compositions generally comprising greater than 80 wt % nickel, nickel-manganese-cobalt (NMC) chemical compositions, nickel-cobalt-aluminum (NCA) chemical compositions, nickel-cobalt-manganese-aluminum (NCMA) chemical compositions, lithium-manganese-iron phosphate (LMFP) chemical compositions, superlithiated oxide (OLO) chemical compositions, lithium-cobalt oxide (LCO) chemical compositions, The chemical compositions of lead acid, chemical compositions of nickel-cadmium, chemical compositions of nickel-metal hydride, chemical compositions of zinc-carbon, or any other type of chemical composition.The first battery pack 100 and the second battery pack 205 may have different cell shape factors (e.g., cylindrical cells, prismatic cells, pouch cells, etc.). The first battery pack 100 and the second battery pack 205 may have different battery module designs (e.g., no modules, stacked modules). The first battery pack 100 and the second battery pack 205 may have different numbers of modules or cells, e.g., the first battery pack 100 may have more cells than the second battery pack 205. Moreover, the first battery pack 100 and the second battery pack 205 may have different dimensions or form factors, e.g., different lengths, widths, and thicknesses.Any number of battery packs may be designed to include a common connection point or region for coupling to the HVDB 175. For example, the first battery pack 100 and the second battery pack 205 may be designed to include a connection point or region for coupling to the HVDB 175. For example, the first battery pack 100 and the second battery pack 205 may each include a similar or equal opening 180 in a lateral side 140 of a housing 105 of the first battery pack 100 or the second battery pack 205. Each of the first battery pack 100 and the second battery pack 205 may be designed and constructed with electrical or thermal connectors of a defined size, shape, or orientation to couple to the HVDB 175 at the opening 180. In this regard, the HVDB 175 may be configured to be coupled to either the first battery pack 100 or the second battery pack 205, although the first battery pack 100 and the second battery pack 205 may have different configurations.The HVDB 175 may be coupled to a side of the battery pack 100 or 205, which, when the battery packs 100 or 205 are installed in an electric vehicle, positions the HVDB 175 at a central point or in the center of the vehicle. By positioning the HVDB 175 in the center of the vehicle, the HVDB 175. By placing the HVDB 175 at a central point within a vehicle, the HVDB 175 may be protected from vehicle impact and is less affected by vibrations or shocks.Referring now to FIGS. 3-5, there is shown, among other things, an example HVDB 175 coupled to the battery pack 100. The HVDB 175 and the battery pack 100 may be two separate boxes.

The actions described herein may be performed in a different order.Having now described some illustrative implementations, it will be apparent that the foregoing is illustrative and not restrictive, as it has been presented by way of example. Although many of the examples presented herein include specific combinations of methods or system elements, these acts and elements may be combined in other ways to achieve the same goals. Acts, elements, and features discussed in connection with an implementation are not intended to be excluded from a similar role in other implementations or implementations.The terminology used herein is for the purpose of description and should not be considered as limiting. The use of "including", "comprising", "including", "containing", "including", "characterized by", "characterized in that", and variations thereof herein is intended to include the items listed below, their equivalents and additional items, as well as alternative implementations consisting solely of the items listed below. In one implementation, the systems and methods described herein consist of any combination of more than one or all of the described elements, acts, or components.Any reference to implementations or elements or acts of the systems and methods referred to herein in the singular may also include implementations including a plurality of these elements, and any reference to an implementation or element or act herein in the plural may also include implementations including only a single element. References in the singular or plural are not intended to limit the presently disclosed systems or methods, their components, acts, or elements to single or multiple configurations. References to an action or element being based on information, action, or element may include implementations where the action or element is based at least in part on information, action, or element.Each implementation disclosed herein may be combined with any other implementation or embodiment, and references to "one implementation", "some implementations", "one implementation", or the like are not necessarily mutually exclusive and are intended to indicate that a particular feature, structure, or characteristic described in connection with the implementation may be included in at least one implementation or embodiment. The terms used herein do not necessarily all refer to the same implementation. Each implementation may be combined with any other implementation, including or excluding, in any manner consistent with the aspects and implementations disclosed herein.References to "or" may be understood to be inclusive, such that any term described with "or" may refer to a single, more than one, or all of the described terms. References to at least one term from a conjunctival list of terms may be construed as an inclusive OR to refer to a single, more than one, or all of the terms described. For example, a reference to "at least one of "A" and "B" may include only "A", only "B", as well as both "A" and "B". Such references used in connection with "comprising" or other open terminology may include other items.Where technical features in the drawings, the detailed description, or a claim are followed by reference numerals, the reference numerals have been included to enhance the intelligibility of the drawings, the detailed description, and the claims. Therefore, neither the reference numerals nor their lack have a limiting effect on the scope of the individual claim elements.Modifications to the described elements and acts, such as variations in sizes, dimensions, structures, shapes, and proportions of the various elements, values of parameters, arrangements for mounting, use of materials, colors, orientations, may occur without materially compromising the teachings and advantages of the subject matter disclosed herein. For example, elements shown as integral may be comprised of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the type or number of individual elements or positions may be varied or varied. Other substitutions, modifications, changes, and omissions may also be made in the design, operating state, and arrangement of the disclosed elements and operations without departing from the scope of the present disclosure.For example, the techniques for implementing a package independent HVBD may also be applied to other modules or devices of a battery pack. For example, the techniques described herein may be applied to a package independent battery management system coupled to an exterior of a battery pack and interfaced to the battery pack. For example, the techniques described herein may be applied to a package independent battery monitoring system coupled to an exterior of a battery pack and interfaced to the battery pack to monitor the state of the batteries of the battery pack. For example, descriptions of positive and negative electrical properties may be reversed. Elements described as negative elements may instead be configured as positive elements, and elements described as positive elements may instead be configured as negative elements. For example, elements described as having a first polarity may instead have a second polarity, and elements described as having a second polarity may instead have a first polarity. Other relative parallel, perpendicular, vertical, or other positioning or orientation descriptions include variations within + / -10% or + / -10 degrees of pure vertical, parallel, or perpendicular positioning. References to "about," "substantially," or other terms include + / -10% variations from the stated measurement, unit, or range, unless expressly stated otherwise. Coupled elements may be electrically, mechanically, or physically coupled together, directly, or with intervening elements. The scope of the systems and methods described herein will therefore be apparent from the appended claims rather than from the foregoing description, and changes which come within the meaning and range of equivalence of the claims are intended to be embraced therein.
