DETAILED DESCRIPTION

[0015] Embodiments described herein provide a battery backup device and system for a garage door opener. The battery backup device includes a housing and one or more accessory ports for receiving one or more accessories (e.g., a battery pack, a battery pack charger, a speaker, a security camera, etc.). The battery backup device is configured to receive alternating current (AC) power (e.g., AC mains power). A controller within the battery backup device is configured to selectively control a switch to provide power to an AC power outlet. The controller is also configured to rectify the received AC power to produce DC power for powering the one or more accessories connected to the one or more accessory ports. When the battery backup device is receiving AC power, the controller is configured to control the switch to pass AC power through to the AC power outlet. When the battery backup device is not receiving AC power, the controller is configured to invert DC power drawn from a battery pack (e.g., a battery pack connected to an accessory port) to produce AC power. The produced AC power may be provided to the AC power outlet. The AC power outlet is configured to receive a standard AC power plug from, for example, a garage door opener. As a result, the battery backup device is operable to provide AC power to the AC power outlet regardless of whether AC power is available to the battery backup device. In this way, the garage door opener and/or various accessories connected thereto may continue to function despite a power outage or loss of AC power.

[0016] FIG. 1 illustrates a battery backup device 100 for a garage door opener 200. The battery backup device 100 and the garage door opener 200 may each be suspended from a surface (e.g., a ceiling) of a structure (e.g., a building, a garage, etc.). In some embodiments, one or more accessories may be coupled or connected (e.g., mechanically coupled, electrically connected, etc.) to the battery backup device 100 to form a battery backup system 300. The garage door opener 200 may be mounted on a drive mechanism for raising and lowering a garage door.

[0017] FIG. 2 illustrates the connection between the battery backup device 100, the garage door opener 200, and the system 300. The illustrated battery backup device 100 includes a housing 105, a light 110 (see, e.g., FIG. 4), one or more accessory ports 120 (e.g., sockets, interfaces, USB ports, etc.) for connecting to one or more accessories, and a controller 125. The system 300 includes the battery backup device 100, a first accessory 115A, a second accessory 115B, a third accessory 115C, and a fourth accessory 115D. Each of the accessories 115A-115D may be coupled or connected to the battery backup device 100 via an accessory port 120A-120D. For example, the first accessory 115A may be coupled to a first accessory port 120A. The second accessory 115B may be coupled to a second accessory port 120B. The third accessory 115C may be coupled to a third accessory port 120C. The fourth accessory 115D may be coupled to a fourth accessory port 120D. In some embodiments, battery backup device 100 includes additional or fewer accessory ports 120 and/or the system 300 includes additional or fewer accessories 115. In some embodiments, the accessories 115A-115D couple to each other and/or an accessory port 120A-120D via a plug, a cable, a USB connection, a dongle, etc. (e.g., in a daisy chain arrangement).

[0018] The accessories 115A-115D may include a battery charger, a battery pack (e.g., a removable and rechargeable power tool battery pack), a speaker, a fan, a light, an extension cord reel, a sensor (e.g., a carbon monoxide sensor, an environmental sensor, etc.), a park-assist laser, a smoke alarm, a folding light, a retractable area light, a security camera, an inflator cord reel, a smart device (e.g., a smart speaker), etc. In some embodiments, multiple of the same type of accessory is connected to the battery backup device 100. The operation of each of the variety of accessory devices and the manner in which each of the accessory devices may be coupled to an accessory port is described in greater detail in U.S. Pat. No. 9,978,265, issued on May 22, 2018, the entire content of which is hereby incorporated by reference.

[0019] The battery backup device 100 may additionally include an AC power cable 135 and AC power plug 140 for connecting to a source of AC power (e.g., AC mains power). The battery backup device 100 is configured to receive AC power by way of the AC power cable 135. The received AC power may be provided to the controller 125 and to a switch 130. The AC power provided to the controller 125 may be rectified by the controller 125 to produce DC power. DC power from the controller 125 may be available to be provided to the accessory ports 120A-120D for powering the accessories 115A-115D. For example, the controller 125 is configured to provide DC power to an accessory port 120A-120D when a battery pack is connected to the accessory port 120A-120D to charge the battery pack. In some embodiments, one or more of the accessories 115A-115D is a battery pack. In other embodiments, one or more of the accessories 115A-115D is a battery pack charger, and the battery pack charger is operable to receive one or more battery packs. In some embodiments, the battery backup device 100 does not receive a battery pack through one of the accessory ports 120A-120D. Rather, one end of the battery backup device 100 may be removable or openable and includes a receptacle specifically designed to receive a battery pack (e.g., a removable and rechargeable power tool battery pack). In such embodiments, the battery pack may not occupy one of the accessory ports 120A-120D and an additional accessory (e.g., a non-battery pack accessory) can be connected to the battery backup device 100.

[0020] The controller 125 is also configured to control the switch 130 to selectively provide power to an AC power outlet 145. The AC power outlet 145 may provide AC power to, for example, the garage door opener 200 via an AC power cable 205 and AC power plug 210 of the garage door opener 200. For example, AC power may passes through the battery backup device 100 to the garage door opener 200 during normal operating conditions, and the battery backup device 100 provides backup power to the garage door opener 200 during abnormal operating conditions (e.g., during a power outage). The controller 125 is configured to control the switch 130 to switch between a first mode of operation and a second mode of operation. In the first mode of operation, the battery backup device 100 is configured to pass AC power from the AC power cable 135 to the AC power outlet 145 via the switch 130. In the second mode of operation, the battery backup device 100 is configured to pass power stored in one or more of the accessories 115A-115D or a separate battery pack to the AC power outlet 145 via the switch 130. In some embodiments, changeover from the first mode of operation to the second mode of operation is achieved automatically using a relay when AC power to the battery backup device 100 is lost. In some embodiments, the controller 125 identifies or detects a power loss (e.g., using a sensor) and causes a battery pack and/or an accessory to discharge DC power for powering the garage door opener 200 when input AC power is lost.

[0021] When the battery backup device 100 passes power stored in one or more of the accessories 115A-115D or a separate battery pack to the AC power outlet 145, the controller 125 is configured to invert DC power to produce AC power. An accessory 115A-115D, or battery pack, that stores DC power is, for example, a power tool battery pack configured for powering power tools (e.g., drills/drivers, impact drills/drivers, hammer drills/drivers, saws, routers, etc.). In some embodiments, the accessory ports 120A-120D include a receiving portion for receiving such power tool battery packs. In other embodiments, the power tool battery pack is connected to the battery backup device 100 through a separate receptacle or another accessory, such as a battery pack charger. When connected through a battery charger, the battery pack charger includes a receiving portion for receiving the power tool battery pack, and the battery pack charger uses power received from the controller 125 to charge the battery pack. An exemplary battery pack and battery pack charger that may be connected to the battery backup device 100 are described in greater detail in U.S. Pat. No. 9,978,265, the entire content of which was previously incorporated by reference.

[0022] The battery backup device 100 is configured to pass power stored in one or more of the accessories 115A-115D or separate battery pack to the AC power outlet 145 when the battery backup device 100 detects a loss of AC power. As a result, when AC power is lost (i.e., no AC power is received via AC power cable 135) the battery backup device 100 is able to provide power to the garage door opener 200, and the garage door opener 200 remains operable to raise or lower a garage door, emit light, and/or the like. The garage door opener 200 may be operated based on signals received from, for example, a wall-mounted keypad, a passcode keypad, and/or a peripheral device (e.g., a smartphone-based application, etc.). The operation of an exemplary garage door opener is described in greater detail in U.S. Pat. No. 9,978,265, the entire content of which was previously incorporated by reference.

[0023] The operation of the battery backup device 100 and/or system 300 may be controlled, monitored, and/or regulated using the controller 125. FIG. 3 illustrates the controller 125 of the battery backup device 100 and system 300. The controller 125 is electrically and/or communicatively connected to a variety of modules or components of the battery backup device 100. For example, the illustrated controller 125 is connected to the light 110, the first accessory port 120A, the second accessory port 120B, the third accessory port 120C, the fourth accessory port 120D, a power input module 305, and a power output module 310. The controller 125 includes combinations of hardware and software that are operable to, among other things, control the operation of the battery backup device 100, control the power supplied to the accessory ports 120A-120D, control the switch 130, convert AC power to DC power, convert DC power to AC power, etc.

[0024] In some embodiments, the controller 125 includes a plurality of electrical and electronic components that provide power, operational control, and/or protection to the components and modules within the controller 125 and/or battery backup device 100. For example, the controller 125 includes, among other things, a processing unit 315 (e.g., a microprocessor, a microcontroller, or another suitable programmable device), a memory 320, input units 325, and output units 330. The processing unit 315 includes, among other things, a control unit 335, an arithmetic logic unit (ALU) 340, and a plurality of registers 345 (shown as a group of registers in FIG. 3), and is implemented using a known computer architecture (e.g., a modified Harvard architecture, a von Neumann architecture, etc.). The processing unit 315, the memory 320, the input units 325, and the output units 330, as well as the various modules connected to the controller 125 are connected by one or more control and/or data buses (e.g., common bus 350). The control and/or data buses are shown generally in FIG. 3 for illustrative purposes. The use of one or more control and/or data buses for the interconnection between and communication among the various modules and components would be known to a person skilled in the art in view of this disclosure.

[0025] The memory 320 is a non-transitory computer readable medium that includes, for example, a program storage area and a data storage area. The program storage area and the data storage area may include combinations of different types of memory, such as read-only memory (ROM), random access memory (RAM) (e.g., dynamic RAM [DRAM], synchronous DRAM [SDRAM], etc.), electrically erasable programmable read-only memory (EEPROM), flash memory, a hard disk, an SD card, or other suitable magnetic, optical, physical, or electronic memory devices. The processing unit 315 is connected to the memory 320 and executes software instructions that are capable of being stored in a RAM of the memory 320 (e.g., during execution), a ROM of the memory 320 (e.g., on a generally permanent basis), or another non-transitory computer readable medium such as another memory or a disc. Software included in the implementation of the battery backup device 100 may be stored in the memory 320 of the controller 125. The software includes, for example, firmware, one or more applications, program data, filters, rules, one or more program modules, and other executable instructions. The controller 125 is configured to retrieve from memory and execute, among other things, instructions related to the control of the battery backup device 100 described herein. In other embodiments, the controller 125 includes additional, fewer, or different components.

[0026] The power input module 305 includes, for example, the AC power cable 135, the AC power plug 140, and a rectifier circuit for converting input AC power to DC power. In some embodiments, the power input module 305 also includes one or more sensors (e.g., a voltage sensor, a current sensor, etc.) for detecting the presence or absence of AC power. The power input module 305 is illustrated as being separate from and connected to the controller 125. However, in some embodiments, components of the power input module 305 may also be included within the controller 125.

[0027] The power output module 310 includes, for example, the switch 130, the AC power outlet 145, and a voltage inverter circuit for converting DC power to AC power. Like the power input module 305, components of the power output module 310 may also be included within the controller 125. For example, for illustrative purposes, the switch 130 and the AC power outlet 145 are illustrated in FIG. 2 as being separate from the controller 125, and a voltage inverter circuit is described as being included within the circuitry of the controller 125.

[0028] FIGS. 4 and 5 illustrate the battery backup device 100 including various accessories. For example, in the embodiments of the battery backup device 100 illustrated in FIGS. 4 and 5, the first accessory 115A is a speaker, the second accessory 115B is a security camera, and the third accessory 115C is a retractable cord reel.
