[0020] A battery system 100 is illustrated in FIG. 1, according to an exemplary

embodiment. Preferably, the battery system 100 includes a lithium-ion battery 110. The battery 110 can be recharged in a charging station or with a charging connector or plug, and reattached to the equipment. As shown, the battery system 100 includes a battery 110, a direct current (DC) power adapter 130, and an alternating current (AC) power adapter 150. The DC power adapter 130 and AC power adapter are separately attachable to the battery 110 to form a DC power adapter assembly 200 and an AC power adapter assembly 300, described further herein with regard to FIGS. 8-9. In some contemplated embodiments, the DC and AC power adapters 130, 150 can both be attached to the battery 110 simultaneously to form a unit including both the DC power adapter 130 and the AC power adapter 150.

[0021] Referring to FIGS. 2-4, the battery 110 includes a housing 115 and multiple female contacts or terminals 124. The female terminals 124 are configured to accept corresponding male contacts or terminals 149 of the DC power adapter 130 or corresponding male contacts or terminals 169 of the AC power adapter 150, as described further herein. As such, the female terminals 124 act as alignment features configured to align with and secure the male terminals of the DC power adapter 130 and the AC power adapter 150 and complete an electrical circuit between the female terminals 124 and the male terminals so that the battery 110 provides electricity to the DC power adapter 130 or the AC power adapter 150, whichever of the two is attached the battery 110. The battery 110 also includes a female guide opening, pocket, or recess 122 that extends into the housing 115. The female guide opening 122 is configured to accept a corresponding male guide protrusion or post 147 of the DC power adapter 130 or a corresponding male guide protrusion or post 167 of the AC power adapter 150. As such, the female guide opening 122 act as an alignment feature and guide configured to align the battery 110 with the adapter 130 or 150 and guide the adapter 130 or 150 into engagement with the battery 110. In other embodiments, the adapters 130 and 150 include the female terminals and female guide openings and the battery 110 includes the male terminals and male guide protrusion. In other embodiments, the battery 110 includes the female terminals and the male guide protrusion and the adapters 130 and 150 include the male terminals and the female guide opening. In other embodiments, the battery 110 includes the male terminals and the female guide opening and the adapters 130 and 150 include the female terminals and the male guide protrusion.

[0022] The housing 115 includes a mating face 112, top 120, bottom 111, left side 118, right side 116, and back 114. As shown in FIG. 2, the female guide opening 122 and terminals 124 are positioned on a mating face 112 of the housing 115 (e.g., shown as front of housing 115). The mating face 112 of the housing 115 is configured as an alignment face such that the face 112 interfaces with, engages, or contacts a corresponding mating face 134, 154 of the DC power adapter 130 and AC power adapter 150, respectively, when the adapters 130, 150 are attached to the battery 110. The mating face 112 of the battery 110 defines a perimeter or foot print. The mating faces 134 and 154 of the adapters 130 and 150 also define a perimeter or foot print. As shown in the illustrated embodiment, the footprints of the battery 110 and the adapters 130 and 150 are the same. In this way, then the adapters 130 or 150 are connected to the battery 110, the adapter 130 or 150 appears to be an extension of the battery 110. Also, there is no portion of the adapter 130 or 150 that overhangs or underhangs the footprint of the battery 110, which may reduce the likelihood of the battery 110 or the adapter 130 or 150 from unwantedly coming into contact with an object and causing the battery 110 and the adapter 130 or 150 to be disconnected.

[0023] The housing 115 has a width 117 and a depth 113. The depth 113 is larger than the width 1 17. In other embodiments, the width 117 may be larger than the depth 113 or may be of the same length. The width 117 and depth 113, along with other dimensions of the battery 110, are configured for ease of handling by an operator. In some embodiments, the housing 115 includes vents 126 positioned on the left side 118 and right side 116 to allow air to flow through the housing 115 to cool the battery 110. Beneficially, when the DC power adapter 130 and/or the AC power adapter 150 is attached to the battery 110, air can still flow through the battery 110 from the vents 126 positioned in the left side 118 and right side 116. In some embodiments, the vents 126 look similar to venting that would be on a standard lead-acid battery, but instead do not act as functional venting. The vents 126 can be used for gripping the battery 110.

[0024] As shown in FIG. 4, the female guide opening 122 extends a distance 121 into the housing 115 of the battery 110 to receive the guide protrusions 147, 167 of the adapters 130, 150 and guide the engagement between the adapters 130, 150 and the battery 110. The female guide opening 122 is circular in cross section. In other embodiments, the female guide opening 122 is rectangular, square, or otherwise shaped. Likewise, the female terminals 124 extend a distance 123 into the housing 115 to receive male terminals 149, 169 of the adapters and to attach the adapters 130, 130 to the battery 110 and to complete the electrical connection between the adapters 130, 150 and the battery 110. The female terminals 124 may extend varying distances into the housing 115. As such, some female terminals 124 may extend a further distance into the housing 115 than other female terminals 124. The female terminals 124 are rectangular in cross-section. In other embodiments, the female terminals 124 may be otherwise shaped. The inner walls of the female components 122, 124 mate with the male components of the DC and AC power adapters (e.g., components 147, 149, 167, 169) to secure the adapters 130, 150 to the battery 110 when the two are connected.

[0025] The battery 110 includes one or more battery packs 190 housed with the housing 115. The battery packs 190 include one or more rechargeable battery cells. The battery pack 190 is electrically connected to the female terminals 124 so that electricity from the battery pack 190 can be communicated to a device connected to the female terminals (e.g., portable power equipment, the adapters, outdoor power equipment, etc.). In some embodiments, the cells are lithium-ion cells and may be MC, LFP, LCO, or other suitable battery chemistry. In one embodiment, the cells include " 18-650" cells due to their 18 mm diameter and their 65 mm length. According to another embodiment, "20-650" cells are utilized. "20-650" cells are 20 mm diameter and their 65 mm length. In some embodiments, the cells are configured in a series-parallel configuration, otherwise known as an "S-P" configuration. For example, multiple cylindrical cells may be coupled in parallel, coupled serially with the parallel combination of cells, or coupled only serially. In some embodiments, the battery 110 may include circuitry or software to protect the battery pack 190 from overcharging, overheating, or other unwanted operating conditions

[0026] Referring to FIG. 5, a DC power adapter 130 is shown, according to an exemplary embodiment. The DC power adapter 130 provides a DC power supply to electronics connected thereto, including sensitive electronics, such as mobile devices, etc. The DC power adapter 130 is configured to attach to the battery 110 and provide a DC power supply when electricity may not otherwise be available to an operator. The DC power adapter 130 can be used to power any electronic devices connectable to the adapter 130 by a universal serial bus (USB) port or a DC outlet.

[0027] The DC power adapter 130 includes a housing 135 and various outlets, including, but not limited to, a DC outlet 144 with an outlet cap 146, and one or more USB ports 142. The housing includes a mating face 134, top portion 140, bottom portion 131, left side portion 138, right side portion 136, and front portion 132. The DC outlet 144 and USB port 142 are positioned on the top portion 140 of the housing 135. In other embodiments, one or both the DC outlet 144 and the USB port 142 may be positioned on the side portions 138, 136 or the front portion 132 of the housing 135. A cap 102 may be provided with the adapter 130 to cover the end of the housing 135 which may have female mating features positioned on the front portion 132. In some embodiments, these mating features may be configured to mate with the male mating features on the AC power adapter 150.

[0028] The housing 135 of the DC power adapter 130 has a width 137 and a depth 133. The depth 133 is larger than the width 137. In other embodiments, the width 137 may be larger than the depth 133 or may be of the same length. In some embodiments, the depth 133 is approximately three inches. In other embodiments, the depth 133 may be longer or shorter than three inches. The width 137 and depth 133, along with other dimensions of the adapter 130, are configured for ease of handling by an operator. As such, the operator may pick up the adapter 130 with one hand if desired. Additionally, the adapter 130 may be stored in small spaces within a vehicle or bag for transportability.

[0029] The housing 135 further includes male components 147, 149 configured to align and mate with the female components 122, 124, respectively, of the battery 110. As described above, the inner walls of the female components 122, 124 mate with the male components of the DC power adapter (e.g., components 147, 149) to secure the DC power adapter 130 on the battery 110 when attached. In an exemplary embodiment as shown in FIG. 8, in an attached position (e.g., DC power adapter assembly 200), the mating face 134 of the housing 135 contacts the mating face 112 of the battery 110.

[0030] The DC outlet 144 is configured to supply DC power to electrical equipment attached thereto. The DC outlet 144 may include a 12 V outlet, a 3 -pin or 4-pin snap-and- lock DC power connector, a Molex connector, a Tamiya connector, etc. The DC outlet 144 may provide various ranges of voltages. For example, the DC outlet 144 may supply power at 6 V, 12 V, 24 V, 36 V, 48 V, or anywhere in the range of 6-48 V. The DC adapter may include a DC-DC power converter to change the voltage level or otherwise condition the DC current provided by the battery 110. The DC outlet 144 may include an outlet cap 146 that can be used to cover the DC outlet 144 when not in use such that the DC outlet 144 is sealed from debris or fluid that may otherwise enter the housing 135.

[0031] The USB port 142 can be used as an output to power or charge a device such as a mobile device, speakers, etc., using the DC power input from the battery 110. Although four USB ports 142 are shown in FIG. 5, more or less USB ports 142 can be included on the housing 135. Various types of USB ports 142 can be included, such as a type- A receptacle, type-B receptacle, type-C receptacle, mini-A receptacle, mini-B receptacle, mini-AB receptacle, micro-B receptacle, micro- AB receptacle, and so on. The USB port 142 may supply DC power at approximately 5 V.

[0032] Referring to FIG. 8, a DC power adapter assembly 200 is shown, according to an exemplary embodiment. The DC power adapter assembly 200 includes the DC power adapter 130 attached to the battery 110 via mating features (e.g., female components 122, 124 and male components 147, 149) as described above. To attach the DC power adapter assembly 200, an operator can slide the male components 147, 149 into the female components 122, 124, respectively, until the mating face 134 of the DC power adapter 130 contacts the mating face 112 of the battery 110. In some embodiments, the male guide protrusion 147 is longer than the male terminals 149 so that the interaction of the male guide protrusion 147 and the female guide opening 122 serves to guide the male terminals 149 and the female terminals 124 into alignment with each other. The DC power adapter 130 receives input power from the battery 110 and supplies the power as a DC power supply via various outlet types. The DC power supply can be used for various applications, such as a traditional DC power supply for powering mobile devices, laptops, and other sensitive electronics, such as speakers, etc. The DC power adapter assembly 200 provides a portable alternative for DC power supply. As such, the operator can use the DC power adapter assembly 200 for various uses while away from home, such as on road trips, camping trips, etc., or can place the DC power adapter assembly 200 in their car and use it as an emergency backup power supply in case of electronics running out of power (e.g., mobile device battery dying).

[0033] Referring to FIG. 6, an AC power adapter 150 is shown, according to an exemplary embodiment. The AC power adapter 150 includes an AC -DC power converter or inverter configured to convert (e.g., invert) the DC current power from either the battery 110 or the DC power adapter 130 into AC current.

[0034] The AC power adapter 150 includes a housing 155 and various outlets, including, but not limited to, a 230 volt AC outlet 164 and a 120 volt AC outlet 162. In further embodiments, various other outlets are provided (e.g., outlets suitable for use with European or other non-United States-style electrical plugs). The housing 155 includes a mating face

154, top portion 160, bottom portion 151, left side portion 158, right side portion 156, and front portion 152. The outlets 162, 164 are positioned on the top portion 160 of the housing

155. In other embodiments, the outlets 162, 164 may be positioned on the left or right side portions 158, 156 of the housing 155. In other embodiments, the outlets 162, 164 may be positioned on the front portion 152 of the housing 155. A cap 102 may be provided with the adapter 150 to cover the end of the housing 155 which may have further mating features or outlets positioned on the front portion 152.

[0035] The housing 155 has a width 157 and a depth 153. The depth 153 is larger than the width 157. In other embodiments, the width 157 may be larger than the depth 153 or may be of the same length. In some embodiments, the depth 153 is approximately five inches. In other embodiments, the depth 153 may be longer or shorter than five inches. The width 157 and depth 153, along with other dimensions of the adapter 150, are configured for ease of handling by an operator. As such, the operator may pick up the adapter 150 with one hand if desired. Additionally, the adapter 150 may be stored in small spaces within a vehicle or bag for transportability.

[0036] The housing 155 further includes male components 167, 169 configured to align and mate with the female components 122, 124, respectively, of the battery 110. As described above, the inner walls of the female components 122, 124 mate with the male components of the AC power adapter 150 (e.g., components 167, 169) to secure the AC power adapter 150 on the battery 110 when attached. In an exemplary embodiment as shown in FIG. 9, in an attached position (e.g., AC power adapter assembly 300), the mating face 154 of the housing 155 contacts the mating face 112 of the battery 110.

[0037] Referring to FIG. 6A, in some embodiments, the DC power adapter 130 is configured as a jump start adapter and includes an energy storage device (e.g., electrical storage device) and a controller 184. In some embodiments, the energy storage device is or includes multiple capacitors, where the capacitors are configured to charge and release electrical energy in a relatively short (e.g., less than 10 seconds), high amperage output (e.g. 12 volts at 300 amps) suitable for jump starting an internal combustion engine (e.g., for a car, boat, motorcycle, or other engine-driven equipment). In some such embodiments, some of the capacitors are coupled with one another in groups (e.g., series or parallel), and the groups are configured to output sequentially in time with respect to one another. Accordingly, the capacitors are specifically configured to be able to power larger applications without much additional energy storage capacity so as to be relatively compact in size and inexpensive. The controller 184 electrically connects the energy storage device to power the components connected to the DC power adapter 130. In some embodiments, the controller 184 can cut power to the application and/or perform high-side switching of the battery power source or low-side switching of the ground side of the circuit when the controller 184 determines that the sufficient supply of power is provided (e.g., when jump-starting a car).

[0038] In some embodiments, as shown in FIG. 6 A, the DC power adapter 130 includes a positive terminal 168 and a negative terminal 170 positioned on the top portion 160 of the housing 155. The terminals 168 and 170 are electrically connected to the energy storage device. In alternative embodiments, the terminals can be mounted on a side of the housing. In some embodiments, caps can be included with the DC power adapter 130 to protect/cover the terminals 168, 170 when not in use. The terminals 168 and 170 are terminals similar to those found on a lead-acid starting battery so that the same jumper cable electrical leads used to electrically connect the positive terminal and the negative terminal of a standard lead-acid battery to a piece of equipment are also used to electrically connect the positive terminal 168 and the negative terminal 170 of the battery adapter system 100 to a piece of equipment. The positive terminal 168 and the negative terminal 170 may be spaced apart by a distance 171 substantially the same as a standard distance between terminals of a standard lead-acid starting battery.

[0039] Referring to FIG. 6B, in other embodiments, a pair of jump starter cables 192 and 194 may be incorporated with the housing 155 instead of the positive and negative terminals as described above. As such, the DC power adapter 130 may be used as an all-in-one jump starter unit for ease of use for the operator. When using the DC power adapter 130 as shown in FIG. 6B, the operator does not need to have jump starter cables available in addition to the adapter 130 and instead can use the cables and clamps incorporated with the adapter 150. The DC power adapter 130 can be capable of several jump starts of an engine depending on the type of engine, power needed to start the engine, and the charge level of the battery 110. For example, the DC power adapter 130 may be capable of approximately three cold starts and approximately ten normal starts of a vehicle when used with a fully-charged battery 110. Using the DC power adapter 130, an operator can jump-start their car, boat, tractor, etc. Beneficially, the DC power adapter 130 is portable and can be for instance, carried onto a boat in case the boat needs a jump start. Furthermore, an operator can place DC power adapter 130 and a battery 110 into his car and have means for jump-starting the car if necessary, providing a safety net for drivers that may get stranded with a dead car battery.

[0040] Referring to FIG. 9, an AC power adapter assembly 300 is shown, according to an exemplary embodiment. The AC power adapter assembly 300 includes the AC power adapter 150 attached to the battery 110 via mating features (e.g., female components 122, 124 and male components 167, 169) as described above. To attach the AC power adapter assembly 300, an operator can slide the male components 167, 169 into the female components 122, 124 until the mating face 154 of the AC power adapter 150 contacts the mating face 112 of the battery 110. In some embodiments, the male guide protrusion 167 is longer than the male terminals 169 so that the interaction of the male guide protrusion 167 and the female guide opening 122 serves to guide the male terminals 169 and the female terminals 124 into alignment with each other. The AC power adapter 150 receives input power from the battery 110 and inverts the power to an AC power supply. The AC power supply can be used for various applications, such as a traditional AC power supply for various types of electrical equipment, including radios, lights, electric stove tops, charging units or power supplies for phones, tablets, laptops, smart devices, televisions, projectors, etc.

[0041] As mentioned above, the DC power adapter 130 and AC power adapter 150 to form either the DC power adapter assembly 200 or the AC power adapter assembly 300. In some embodiments, the DC power adapter 130 and AC power adapter 150 can be attached simultaneously to the battery 1 10 such that both AC and DC power is readily available (e.g., with the DC power adapter 130 positioned between the battery 110 and the AC power adapter 150. Beneficially, when all components are attached, the various outlets are positioned on the top of the adapters and easily available to an operator. Additionally, an operator can have both the DC power adapter 130 and AC power adapter 150 available to attach either adapter separately to the battery 110 for the proper power supply. As such, the operator can easily transport all three components on a road trip, camping trip, boating trip, or for everyday emergency use.

[0042] The adapters 130 and 150 may be bundled together for sale as a single package. Alternatively, one or more of the adapters 130 and 150 is bundled with one or more batteries 110, and a charging device to recharge the battery 110. This package could be further bundled with one or more pieces of power equipment powerable by the battery 110. In some embodiments, the battery 110 and the other components of any of these bundles are configured as proprietary components such that the battery 110 can only be connected to components from the same product line or brand. [0043] The construction and arrangement of the apparatus, systems and methods as shown in the various exemplary embodiments are illustrative only. Although only a few

embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.). For example, some elements shown as integrally formed may be constructed from multiple parts or elements, the position of elements may be reversed or otherwise varied and the nature or number of discrete elements or positions may be altered or varied. Accordingly, all such modifications are intended to be included within the scope of the present disclosure. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present disclosure.
