Description

Technical Field

[0001] This disclosure relates to the field of power supply technology, and more particularly to a power adapter and charging system. Background Technology

[0002] With technological advancements, an increasing number of power tools are using battery packs as their power source. Battery-powered power tools are freed from the constraints of cables, making them easier for operators to use in various work environments.

[0003] Among various power tools, especially garden power tools, taking electric gardening vehicles (such as electric ride-on lawnmowers) as an example, these vehicles have a battery compartment that can receive an onboard battery pack or other battery packs of different specifications. These battery packs provide power to the vehicle, for example, to drive the vehicle and operate the tools. These other battery packs can also power other cordless power tools. For example, they can power garden tools such as handheld lawnmowers, pruning shears, hair dryers, and chainsaws; torque-output power tools such as electric drills and hammer drills; sawing tools such as circular saws, jigsaws, and reciprocating saws; or grinding tools such as angle grinders and sanders. Generally, when the battery capacity of the electric gardening vehicle is depleted, it can be recharged via a vehicle charger connected to the charging port using AC power, solar power, or a generator.

[0004] However, in related technologies, the vehicle chargers are specifically designed for electric gardening vehicles and can only charge these vehicles. They cannot charge other electrical equipment or directly charge battery packs, thus limiting their application. For example, other battery packs require separate battery pack chargers, meaning users of electric gardening vehicles and cordless power tools need to purchase both a vehicle charger and a battery pack charger, increasing user costs.

[0071] In related technologies, the power adapters are specifically designed for electric gardening vehicles and can only charge these vehicles; they cannot charge other electrical equipment or directly charge battery packs. Therefore, this disclosure provides a power adapter and charging system capable of outputting electrical energy to external electrical equipment and energy conversion devices, addressing the problems in related technologies.

[0072] This disclosure provides a power adapter equipped with a power input interface or power input connector and a power output interface. Using the power output interface, it can be selectively electrically connected to an external electrical device or to an energy conversion device, thereby selectively outputting corresponding electrical energy to the electrically connected external electrical device or energy conversion device.

[0073] Please see Figure 1 The diagram shows a schematic representation of a power adapter according to an embodiment of this disclosure. Figure 1 As shown, the power adapter 1 includes an adapter body 11, a power input connector 13, a power output interface 15, and a charging cable 200.

[0074] Preferably, the adapter body 11 is a hexahedral box-shaped structure with an outer shell. The outer shell of the adapter body 11 can be made of flame-retardant ABS plastic. The outer shell can form an accommodating space, within which a power main control board can be built. The power main control board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions. Exemplarily, the power main control board can be fixed to the outer shell by screws. Exemplarily, the power main control board can be fixed to the outer shell by a thermally conductive adhesive potting process.

[0075] In some embodiments, the power supply main control board includes an AC-DC conversion module, a voltage conversion module, and a power management module.

[0076] The AC-DC conversion module converts the input alternating current (AC) into direct current (DC). For example, the AC-DC conversion module may be a rectifier.

[0077] The voltage conversion module can be electrically connected to the AC-DC conversion module for voltage conversion. There can be more than one voltage conversion module. For example, one voltage conversion module is connected to the output terminal of the AC-DC conversion module to convert the signal at the output terminal of the AC-DC conversion module into a first operating voltage. For example, two voltage conversion modules are connected to the output terminal of the AC-DC conversion module, wherein the first voltage conversion module converts the signal at the output terminal of the AC-DC conversion module into the first operating voltage, and the second voltage conversion module converts the signal at the output terminal of the AC-DC conversion module into a second operating voltage. For example, a first voltage conversion module is connected to the output terminal of the AC-DC conversion module, and a second voltage conversion module is connected to the output terminal of the first voltage conversion module, wherein the first voltage conversion module converts the signal at the output terminal of the AC-DC conversion module into the first operating voltage, and the second voltage conversion module converts the signal at the output terminal of the first voltage conversion module into the second operating voltage. For example, the voltage conversion module can be a transformer.

[0078] In some embodiments, the power supply main control board further includes a filter circuit and a voltage regulator circuit. For example, the filter circuit and the voltage regulator circuit are connected sequentially to the voltage conversion module.

[0079] In some embodiments, the power supply main control board further includes a power supply path selection circuit connected to the power management module. The power supply path selection circuit is used to select either a first power supply path corresponding to the external electrical device or a second power supply path corresponding to the energy conversion device, depending on whether the power output interface is electrically connected to an external electrical device or an energy conversion device.

[0080] In some embodiments, the power supply main control board is also provided with an overcharge protection circuit.

[0081] In some embodiments, the adapter body 11 is provided with at least one charging indicator light electrically connected to the power main control board, used to display a corresponding light according to the current charging status. For example, when the power adapter 1 is charging, the charging indicator light is red. When the power adapter 1 has finished charging, the charging indicator light is green. When the power adapter 1 experiences a charging failure, the charging indicator light flashes red.

[0082] In some embodiments, the adapter body 11 is provided with a display screen electrically connected to the power main control board, used to display corresponding information according to the current charging status. For example, the display screen can display charging power, charging time, estimated remaining charging time, etc. For example, when the power adapter 1 experiences a charging failure, the display screen can display the type of charging failure, etc.

[0083] In some embodiments, heat dissipation fins may also be provided inside the adapter body 11 for heat dissipation. Exemplarily, the heat dissipation fins are fixedly disposed inside the housing of the adapter body 11 and correspond to the heat dissipation source on the power supply main control board. Exemplarily, the heat dissipation fins are fixedly disposed on the power supply main control board and correspond to the heat dissipation source on the power supply main control board. The heat dissipation fins may be, for example, aluminum heat dissipation fins or stainless steel heat dissipation fins.

[0084] In some embodiments, a cooling fan and a heat dissipation vent may also be provided inside the adapter body 11. For example, the cooling fan is fixed to the main power control board by means of clips or screws, and the heat dissipation vent may be located on one or more sides of the adapter body 11. The cooling fan drives airflow to blow the heat generated by the heat source on the main power control board to the heat dissipation vent for dissipation. Thus, when the power adapter 1 supports wall mounting, the heat dissipation vent located on the side of the power adapter 1 can still operate normally.

[0085] The power input connector 13 is connected to the main power control board via an input wire, and can be connected to AC power to input electrical energy. Exemplarily, the power input connector 13 is a two-prong plug. Exemplarily, the power input connector is a three-prong plug with a grounding terminal.

[0086] The power output interface 15 is disposed on the surface of the adapter body 11 and electrically connected to the power main control board. In some embodiments, the power input connector 13 may be disposed on a first side of the outer shell of the adapter body 11, and the power output interface 15 may be disposed on a second side of the outer shell of the adapter body 11, wherein the first side and the second side may be arranged opposite to each other, or the first side and the second side may be arranged adjacent to each other, or the first side and the second side may be on the same side.

[0087] Using the power output interface 15, the device can be electrically connected to an external electrical device or energy conversion device via the charging cable 200 that is matched with the power output interface 15 to output corresponding electrical energy.

[0088] For example, an external electrical device can be electrically connected via the power output interface 15 to charge the battery pack in the external electrical device.

[0089] The external power equipment is equipped with a rechargeable battery pack. In some embodiments, the external power equipment may include an electric gardening vehicle capable of performing gardening operations such as pruning, mowing, spraying, watering, and spraying pesticides; for example, an electric ride-on lawnmower or an electric pesticide sprayer. In some embodiments, the external power equipment may include portable electric gardening equipment capable of performing gardening operations such as pruning, mowing, spraying, pruning, and debris removal; for example, a backpack lawnmower, a chainsaw, or a garden blower.

[0090] Please see Figure 2 Displayed as Figure 1 A schematic diagram illustrating the application of the power adapter in one embodiment. Taking an electric ride-on lawnmower as an example, such as... Figure 2 As shown, the electric ride-on lawnmower 9 has a battery compartment 91, which may be located at the rear end of the frame, or at least partially under the seat. Alternatively, in other embodiments, the battery compartment may also be located at the front end of the frame, and is not limited to the illustration.

[0091] The battery cavity 91 has one or more battery storage spaces. Opening the cover of the battery cavity 91 reveals the structure of multiple battery packs stored within the battery storage spaces. The battery packs can be single-specification battery packs or combinations of multiple specifications of battery packs. For example, the battery packs may include at least one of a first-specification battery pack and a second-specification battery pack. The differences in specifications between the first-specification battery pack and the second-specification battery pack include, but are not limited to, differences in battery pack capacity, voltage, battery internal resistance, weight, size, energy density, cell type, charge information, and battery health status information.

[0092] In some embodiments, the difference between the first-specification battery pack and the second-specification battery pack lies in their battery pack capacities. The first-specification battery pack has a larger capacity than the second-specification battery pack. The second-specification battery pack is configured to power handheld garden tools. For example, the second-specification battery pack can power garden tools such as lawnmowers, pruning machines, hair dryers, and chainsaws. Furthermore, the second-specification battery pack can also power torque-output tools such as electric drills and hammer drills; sawing tools such as circular saws, jigsaws, and reciprocating saws; or grinding tools such as angle grinders and sanders.

[0093] In some embodiments, the difference between the first-specification battery pack and the second-specification battery pack lies in the type of battery cells used. For example, the first-specification battery pack and the second-specification battery pack may respectively use lithium iron phosphate cells, ternary lithium cells, or nickel-cadmium battery cells, lead-acid battery cells, graphene cells, etc.

[0094] The multiple battery units are selected from at least one of the first specification battery pack and the second specification battery pack. This allows the electric ride-on lawnmower to be compatible with different specifications of battery packs, meeting the needs of high-power operation while also being compatible with handheld electric garden tools, making the work of the workers more flexible.

[0095] When using the power adapter 1 provided in this embodiment, when the battery pack in the battery compartment 91 of the electric ride-on lawnmower 9 needs charging due to power loss, the power input connector 13 of the power adapter 1 can be connected to the mains power to input electrical energy. The charging cable 200 with a plug interface and a charging gun is provided. The plug interface of the charging cable 200 is pluggably connected to the power output interface 15 of the power adapter 1, and the charging gun of the charging cable 200 is connected to the charging interface (not shown in the figure) of the electric ride-on lawnmower 9. In this way, the power adapter 1 receives the mains power and outputs the power to the electrically connected electric ride-on lawnmower 9 through a certain conversion to charge the battery pack in its battery compartment 91.

[0096] The energy conversion device is equipped with a rechargeable battery pack. In some embodiments, the energy conversion device is a battery pack charging stand or a battery pack charging device.

[0097] Please see Figure 3 Displayed as Figure 1 A schematic diagram illustrating the application of the power adapter in another embodiment. Taking a battery pack charging dock as an example, as... Figure 3 As shown, the battery pack charging stand 8 has a device body 81.

[0098] The device body 81 has a shell made of flame-retardant ABS plastic, in which a first receiving space can be formed. A charging circuit board can be built into the first receiving space. The charging circuit board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions. In some embodiments, a power conversion unit can be provided on the charging circuit board. Exemplarily, the main power control board can be fixed to the shell by screws. Exemplarily, the main power control board can be fixed to the shell by a thermally conductive adhesive potting process.

[0099] An electrical input interface or electrical input connector is provided on the surface of the device body 81.

[0100] Taking the power input connector as an example, the power input connector is connected to the charging circuit board through an input wire, and is electrically connected to the power output interface of the power adapter through a cable.

[0101] Taking the power input interface as an example, for instance, the plug-in interface of the charging cable 200 is pluggably connected to the power output interface 15 of the power adapter 1, while the charging interface of the charging cable 200 is connected to the power input interface of the battery pack charging socket 8. By providing this power input interface, more options can be offered.

[0102] The battery pack charging stand 8 has at least one energy storage compartment for accommodating the battery pack 80. In some embodiments, the at least one energy storage compartment may be located on the front side of the housing of the device body 81, and may be a semi-open or open structure design, thus allowing the battery pack 80 to be conveniently placed or removed into the corresponding energy storage compartment. In some embodiments, the at least one energy storage compartment may be built into the housing of the device body 81. Exemplarily, a second accommodating space may be formed within the housing of the device body 81, and at least one energy storage compartment may be formed within the second accommodating space. Alternatively, exemplarily, at least one third accommodating space may be formed within the housing of the device body 81, and an energy storage compartment may be formed within each third accommodating space. Exemplarily, the second accommodating space may be connected to or shared with the aforementioned first accommodating space, or exemplarily, the at least one third accommodating space may be connected to or partially shared with the aforementioned first accommodating space.

[0103] The energy storage compartment is equipped with a charging terminal for forming an electrical connection with the conductive terminals of the battery pack it houses. In some embodiments, one energy storage compartment can house one battery pack, in which case the energy storage compartment is equipped with a charging terminal, and the conductive terminals of the housed battery pack are electrically connected to the charging terminal. In some embodiments, one energy storage compartment can house two or more battery packs, in which case the energy storage compartment is equipped with two or more charging terminals, and the conductive terminals of the two or more housed battery packs can be electrically connected to the corresponding charging terminals.

[0104] As mentioned above, a power conversion unit may be provided on the charging circuit board. The power conversion unit is electrically connected to the power input interface and the charging terminal, and is used to charge the battery pack electrically connected to the charging terminal based on the power input interface.

[0105] When using the power adapter 1 provided in this embodiment, the battery pack 80 that needs to be charged is placed in the energy storage compartment of the battery pack charging base 8. The conductive terminals of the battery pack are electrically connected to the charging terminals in the energy storage compartment. The power input connector 13 of the power adapter 1 can be connected to the mains power to input electrical energy. Through the power output interface of the power adapter, the charging cable 200, and the power input interface or power input connector of the battery pack charging base 8, the power adapter 1 is electrically connected to the battery pack charging base 8. In this way, the power adapter 1 receives the electrical energy from the mains power and outputs the electrical energy to the electrically connected battery pack charging base 8 through a certain conversion to charge the battery pack in its energy storage compartment.

[0106] The power adapter provided in the above embodiments is equipped with a power input connector and a power output interface. Using the power output interface, it can be electrically connected to external electrical equipment or to an energy conversion device. In this way, it can output corresponding electrical energy to the electrically connected external electrical equipment or energy conversion device. Compared with the dedicated power adapters in the current technology, it has greater scalability, is convenient to use, and can save costs.

[0107] Please see Figure 4 The diagram shows a schematic representation of the power adapter in another embodiment of this disclosure. Figure 4 As shown, the power adapter 2 includes an adapter body 21, a power input interface 23, a power output interface 25, and a charging cable 200.

[0108] The adapter body 21 has an outer shell, which may be made of flame-retardant ABS plastic. The outer shell can be enclosed to form an accommodating space, in which a power main control board may be built. The power main control board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions.

[0109] In some embodiments, the power supply main control board includes an AC-DC conversion module, a voltage conversion module, and a power management module.

[0110] The AC-DC conversion module converts the input alternating current (AC) into direct current (DC). For example, the AC-DC conversion module may be a rectifier.

[0111] The voltage conversion module can be electrically connected to the AC-DC conversion module for voltage conversion.

[0140] In some embodiments, the energy conversion device is a battery pack charging stand or battery pack charging device, which is equipped with a rechargeable battery pack.

[0141] In some embodiments, when an external electrical device is electrically connected through the first power output interface and the second power output interface is unused, the power supply path selection circuit can select a first power supply path corresponding to the external electrical device based on the fact that the first power output interface is electrically connected to the external electrical device.

[0142] Furthermore, it should be noted that the electrical connection between the first power output interface and the external electrical device, and the electrical connection between the second power output interface and the energy conversion device, are merely illustrative examples and are not intended to be limiting. In some other embodiments, the first power output interface may be used to electrically connect to the energy conversion device, and / or the second power output interface may be used to electrically connect to the external electrical device.

[0145] This disclosure provides a charging system including the aforementioned power adapter and energy conversion device. The energy conversion device is electrically connected to the power adapter, the power adapter can output electrical energy to the energy conversion device, and the energy conversion device charges its configured battery pack based on the electrical energy output by the power adapter.

The outer shell, when closed, forms an accommodating space, within which a power main control board can be built. The power main control board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions. Exemplarily, the power main control board can be fixed to the outer shell by screws. Exemplarily, the power main control board can be fixed to the outer shell by a thermally conductive adhesive potting process.

[0150] In some embodiments, the power supply main control board includes an AC-DC conversion module, a voltage conversion module, and a power management module.

[0151] The AC-DC conversion module converts the input alternating current (AC) into direct current (DC). For example, the AC-DC conversion module may be a rectifier.

[0152] The voltage conversion module can be electrically connected to the AC-DC conversion module for voltage conversion. There can be more than one voltage conversion module. For example, one voltage conversion module is connected to the output terminal of the AC-DC conversion module to convert the signal at the output terminal of the AC-DC conversion module into a first operating voltage. For example, two voltage conversion modules are connected to the output terminal of the AC-DC conversion module, wherein the first voltage conversion module converts the signal at the output terminal of the AC-DC conversion module into the first operating voltage, and the second voltage conversion module converts the signal at the output terminal of the AC-DC conversion module into a second operating voltage. For example, a first voltage conversion module is connected to the output terminal of the AC-DC conversion module, and a second voltage conversion module is connected to the output terminal of the first voltage conversion module, wherein the first voltage conversion module converts the signal at the output terminal of the AC-DC conversion module into the first operating voltage, and the second voltage conversion module converts the signal at the output terminal of the first voltage conversion module into the second operating voltage. For example, the voltage conversion module can be a transformer.

[0153] In some embodiments, the power supply main control board further includes a filter circuit and a voltage regulator circuit. For example, the filter circuit and the voltage regulator circuit are connected sequentially to the voltage conversion module.

[0154] In some embodiments, the power supply main control board further includes a power supply path selection circuit connected to the power management module. The power supply path selection circuit is used to select either a first power supply path corresponding to the external electrical device or a second power supply path corresponding to the energy conversion device, depending on whether the power output interface is electrically connected to an external electrical device or an energy conversion device.

[0155] In some embodiments, the power supply main control board is also provided with an overcharge protection circuit.

[0156] In some embodiments, the adapter body 11 is provided with at least one charging indicator light electrically connected to the power main control board, used to display a corresponding light according to the current charging status. For example, when the power adapter is charging, the charging indicator light is red. When the power adapter has finished charging, the charging indicator light is green. When the power adapter experiences a charging failure, the charging indicator light flashes red.

[0157] In some embodiments, the adapter body 11 is provided with a display screen electrically connected to the power supply main control board, for displaying corresponding information according to the current charging status. For example, the display screen may display charging power, charging time, estimated remaining charging time, etc. For example, when the power adapter experiences a charging failure, the display screen may display the type of charging failure, etc.

[0158] In some embodiments, heat dissipation fins may also be provided inside the adapter body 11 for heat dissipation. Exemplarily, the heat dissipation fins are fixedly disposed inside the housing of the adapter body 11 and correspond to the heat dissipation source on the power supply main control board. Exemplarily, the heat dissipation fins are fixedly disposed on the power supply main control board and correspond to the heat dissipation source on the power supply main control board. The heat dissipation fins may be, for example, aluminum heat dissipation fins or stainless steel heat dissipation fins.

[0159] In some embodiments, a cooling fan and a heat dissipation vent may also be provided inside the adapter body 11. For example, the cooling fan is fixed to the main power control board by means of clips or screws, and the heat dissipation vent may be located on one or more sides of the adapter body 11. The cooling fan drives airflow to blow the heat generated by the heat source on the main power control board to the heat dissipation vent for dissipation. Thus, when the power adapter 1 supports wall mounting, the heat dissipation vent located on the side of the power adapter 1 can still operate normally.

[0160] The power input connector / power input interface 13 is connected to the main power control board, and the power input connector / power input interface 13 can be connected to AC power to input electrical energy.

[0161] In some embodiments, a power input connector is used, which is connected to the main power control board via an input wire. This power input connector allows connection to AC power for electrical input. Exemplarily, the power input connector is a two-prong plug. Exemplarily, the power input connector is a three-prong plug with a grounding terminal.

[0162] In some embodiments, a power input interface is employed, which allows connection to AC power for electrical input. For example, a cable is provided with a plug interface and a power input connector, the plug interface of which mates with the power input interface of the power adapter 1, and the power input connector of the cable mates with AC power. Exemplarily, the power input connector is a two-prong plug. Exemplarily, the power input connector is a three-prong plug with a grounding terminal. By providing this power input interface, more options are available.

[0163] At least one power output interface 15 is disposed on the surface of the adapter body and electrically connected to the power main control board. In some embodiments, the number of power output interfaces 15 may be one. In some embodiments, the number of power output interfaces 15 may be two or more.

[0164] Using the power output interface 15, the power can be electrically connected to the energy conversion device via a cable with a plug that matches the power output interface 15 to output corresponding electrical energy, such as the charging cable 200.

[0165] The energy conversion device 6 is equipped with a rechargeable battery pack. In some embodiments, the energy conversion device is a battery pack charging stand or a battery pack charging device.

[0166] Taking a battery pack charging dock as an example, such as Figure 6 As shown, the battery pack charging stand 6 has a device body 61.

[0167] The device body 61 has a shell made of flame-retardant ABS plastic. A first accommodating space is formed within the shell, and a charging circuit board can be built into this space. The charging circuit board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions. In some embodiments, a power conversion unit may be provided on the charging circuit board. Exemplarily, the main power control board can be fixed to the shell by screws. Exemplarily, the main power control board can be fixed to the shell by a thermally conductive adhesive potting process.

[0168] An electrical input interface is provided on the surface of the device body 61.

[0169] Taking the power input connector as an example, the power input connector is connected to the charging circuit board through the charging cable 200. Using the charging cable 200, the power input interface of the device body 61 is electrically connected to the power output interface of the power adapter.

[0170] Taking the power input interface as an example, the charging cable 200 can be plugged into the power output interface of the power adapter 1, while the charging interface of the cable is connected to the power input interface of the battery pack charging socket 6. By providing this power input interface, more options can be offered.

[0171] Please see Figure 7 The diagram shows a structural schematic of an energy conversion device and a battery pack in one embodiment. (Combined with...) Figure 6 and Figure 7 The battery pack charging stand 6 has at least one energy storage compartment 65 for accommodating the battery pack 80. In some embodiments, the at least one energy storage compartment 65 may be disposed on the front side of the housing of the device body 61, and may be a semi-open or open structure design, thereby allowing the battery pack 80 to be conveniently placed or removed into the corresponding energy storage compartment. In some embodiments, the at least one energy storage compartment may be built into the housing of the device body 61. Exemplarily, a second accommodating space may be formed within the housing of the device body 61, and at least one energy storage compartment may be formed within the second accommodating space. For example, a second accommodating space may be formed within the housing of the device body 61, and two energy storage compartments may be formed within the second accommodating space. Alternatively, exemplarily, at least one third accommodating space may be formed within the housing of the device body 61, and one energy storage compartment may be formed within each third accommodating space. For example, two third accommodating spaces may be formed within the housing of the device body 61, and one energy storage compartment may be formed within each third accommodating space. For example, the second accommodating space may be connected to or shared with the aforementioned first accommodating space; or, for example, the at least one third accommodating space may be connected to or partially shared with the aforementioned first accommodating space.

[0172] The energy storage compartment 65 is provided with a charging terminal 651 for forming an electrical connection with the conductive terminals 801 of the battery pack 80 it houses. In some embodiments, one energy storage compartment can house one battery pack 80, in which case the energy storage compartment 65 is provided with a charging terminal 651, and the conductive terminals 801 of the housed battery pack 80 are electrically connected to the charging terminal 651. In some embodiments, one energy storage compartment can house two or more battery packs, in which case the energy storage compartment is provided with two or more charging terminals, and the conductive terminals of the two or more housed battery packs can be electrically connected to the corresponding charging terminals.

[0173] In some embodiments, the battery pack may include at least one of a first power battery and a second power battery. For example, if an energy storage compartment can accommodate one battery pack, the energy storage compartment can accommodate either one first power battery or one second power battery.

[0174] The differences in specifications between the first power battery and the second power battery include, but are not limited to, differences in battery pack shape, capacity, voltage, battery internal resistance, weight, size, energy density, cell type, charge information, and battery health status information.

[0175] In some embodiments, the first power battery may be, for example, a pouch battery, and the battery capacity of the pouch battery may be, for example, 6 amp-hours (Ah), 7 amp-hours (Ah), 8 amp-hours (Ah), 9 amp-hours (Ah), 10 amp-hours (Ah), 11 amp-hours (Ah), 12 amp-hours (Ah), etc.

[0176] In some embodiments, the second power battery may be, for example, a conventional battery pack, and the battery capacity of the conventional battery pack may be, for example, 2 amp-hours (Ah), 2.5 amp-hours (Ah), 3 amp-hours (Ah), 4 amp-hours (Ah), 5 amp-hours (Ah), 6 amp-hours (Ah), 7.5 amp-hours (Ah), etc.

[0177] For example, the battery pack charging stand 6 has an energy storage compartment 65, which can accommodate a first power battery or a second power battery.

[0178] For example, the battery pack charging stand 6 has two energy storage compartments 65. For instance, the first energy storage compartment 65 can hold one first power battery and the second energy storage compartment 65 can hold one first power battery, meaning the battery pack charging stand 6 can charge two first power batteries; or, the first energy storage compartment 65 can hold one first power battery and the second energy storage compartment 65 can hold one second power battery, meaning the battery pack charging stand 6 can charge one first power battery and one second power battery; or, the first energy storage compartment 65 can hold one second power battery and the second energy storage compartment 65 can hold one second power battery, meaning the battery pack charging stand 6 can charge two second power batteries; or, the first energy storage compartment 65 can hold one second power battery and the second energy storage compartment 65 can hold one first power battery, meaning the battery pack charging stand 6 can charge one first power battery and one second power battery.

[0179] In some embodiments, when the total number of battery packs (first power battery and / or second power battery) placed in each energy storage compartment 6 of the battery pack charging base 6 is two or more, the charging of these two or more battery packs is carried out in a predetermined sequence.

[0180] In some embodiments, when the total number of battery packs (first power battery and / or second power battery) placed in each energy storage compartment 6 of the battery pack charging base 6 is two or more, they can be charged simultaneously when charging the two or more battery packs.

[0181] In some embodiments, the battery pack and the energy storage compartment are snap-fitted together.

[0182] Combination Figure 6 and Figure 7 The energy storage compartment 65 may be equipped with a pop-up structure 653 and a locking mechanism.

[0183] The pop-up structure 653 is located at the bottom of the energy storage compartment 65, corresponding to the limiting portion 803 located at the bottom of the battery pack 80. In some embodiments, the pop-up structure 653 is implemented as a protrusion with an elastic member. In the initial state, the protrusion protrudes from the bottom of the energy storage compartment 65 under the elastic force of the elastic member. When the battery pack 80 is to be placed in the energy storage compartment 65, the limiting portion 803 at the bottom of the battery pack 80 corresponds to the protrusion. Under the downward pressure of the limiting portion 803 at the bottom of the battery pack 80, the protrusion overcomes the elastic force of the elastic member and moves inward. Subsequently, the protrusion can move outward under the elastic force of the elastic member and the downward pressure of the battery pack 80 and form a limiting position with the limiting portion 803 at the bottom of the battery pack 80. Exemplarily, the elastic member can be, for example, a compression spring or a sheet spring.

[0184] The locking mechanism 655 is located on the top of the energy storage compartment 65, corresponding to the locking portion 805 located on the top of the battery pack 80. In some embodiments, the locking portion 805 in the battery pack 80 is implemented as a locking groove, and correspondingly, the locking mechanism 655 is implemented as a locking buckle with an elastic member. The locking buckle may further include a buckle body and a protruding locking tongue connected to the buckle body, and the elastic member is associated with the buckle body of the locking buckle. In the initial state, the locking latch's bolt protrudes from the energy storage compartment 65 under the elastic force of the elastic member. When the battery pack 80 is to be placed in the energy storage compartment 65, the locking portion 805 at the top of the battery pack 80 corresponds to the locking bolt. Under the downward pressure of the locking portion 805 at the top of the battery pack 80, the locking bolt overcomes the elastic force of the elastic member and moves inward. Subsequently, the locking bolt can move outward under the elastic force of the elastic member and the downward pressure of the battery pack 80 and lock with the locking portion 805 at the top of the battery pack 80. Exemplarily, the elastic member can be, for example, a compression spring or a sheet spring.

[0185] In some embodiments, the energy storage compartment 65 is provided with an unlocking structure that is linked to the locking mechanism. For example... Figure 7 As shown, an unlocking structure 657, linked to the locking mechanism 655, may be provided above the energy storage compartment 65. In some embodiments, the unlocking structure 657 is implemented as an unlocking switch linked to the latch body in the locking latch. The unlocking switch may be, for example, an unlocking button, an unlocking knob, or an unlocking lever. Taking the unlocking switch as an unlocking button as an example, when it is necessary to remove the battery pack 80 placed in the energy storage compartment 65, pressing the unlocking button will cause the latch body and the locking tongue in the locking latch to move inward, so that the inwardly retracted locking tongue disengages from the locking part 805 in the battery pack 80 to release the lock.

[0186] Furthermore, the energy storage compartment is equipped with an arc protection unit that cooperates with the locking mechanism. During DC charging, when the conductive terminal 801 of the battery pack 80 makes or breaks electrical contact with the charging terminal 651 in the energy storage compartment 65, the contact or separation between the conductive terminal 801 of the battery pack 80 and the charging terminal 651 in the energy storage compartment 65 is under energized conditions. This contact or separation can generate an arc or even an electric spark at the moment of insertion or removal, which can easily lead to accidents. An oxide layer can also form on the conductive terminal 801 of the battery pack 80 or the charging terminal 651 in the energy storage compartment 65, affecting the charging efficiency and even the service life of the battery pack 80 or the battery pack charging socket 6.

[0187] In some embodiments, the arc protection unit includes a micro switch and a pressing element. When the locking mechanism is in a first position, the pressing element and the micro switch are in a first state, and the charging terminal is energized; when the locking mechanism is in a second position, the pressing element and the micro switch are in a second state, and the charging terminal is de-energized.

[0188] Please refer to Figure 8 and Figure 9 ,in, Figure 8 The diagram shown is a structural schematic of the arc protection unit in the first state according to an embodiment of this disclosure. Figure 9 The diagram shown is a structural schematic of the arc protection unit in a second state according to an embodiment of this disclosure. (In conjunction with...) Figures 6 to 9 The arc protection unit includes a micro switch 671 and a pressing member 673. The micro switch 671 is disposed beside the locking mechanism 655 and associated with the charging terminal inside the energy storage compartment. The locking mechanism 655 includes a locking latch and an elastic member. The locking latch may further include a latch body 6551 and a locking tongue 6553 connected to the latch body 6551 and protruding from the surface of the energy storage compartment. The elastic member is implemented as a compression spring 6555 associated with the latch body 6551. The micro switch 671 is fixed to the housing of the energy storage compartment 65 and adjacent to the latch body 6551 of the locking latch. Exemplarily, the micro switch 671 has a trigger button 672, which is directly opposite the latch body 6551 of the locking latch. The pressing member 673 is disposed between the micro switch 671 and the latch body 6551 of the locking latch. Exemplarily, the pressing member 673 has a connecting end and a free end opposite to the connecting end, wherein the connecting end of the pressing member 673 is connected to the micro switch 671 or to the energy storage housing 65, and the free end of the pressing member 673 is located on the movement path of the latch body 6551 in the locking latch, where it moves inward or outward. In some embodiments, the free end of the pressing member 673 may also be provided with a reinforcing portion to enhance contact with the latch body; exemplaryly, the reinforcing portion is implemented as an arc-shaped reinforcing structure provided at the free end of the pressing member 673.

[0189] In some embodiments, when the trigger button of the micro switch 671 is in its natural state (e.g., naturally protruding), the micro switch 671 is in the open state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is energized. When the trigger button of the micro switch 671 is in the pressed state (e.g., retracted under pressure), the micro switch 671 is in the closed state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is de-energized. Alternatively, in some embodiments, when the trigger button of the micro switch 671 is in its natural state (e.g., naturally protruding), the micro switch 671 is in the closed state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is energized. When the trigger button of the micro switch 671 is in the pressed state (e.g., retracted under pressure), the micro switch 671 is in the open state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is de-energized.

[0190] When no battery pack is installed in the energy storage compartment, in the initial state, the locking tongue 6553 of the locking buckle protrudes from the surface of the energy storage compartment 65 under the elastic force of the compression spring 6555. The pressing member 673 in the arc protection unit does not interfere with the buckle body 6551 of the locking buckle and is in the first state. At this time, the micro switch 671 in the arc protection unit is in the natural state (e.g., naturally protruding), the micro switch 671 is in the open state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is in the energized state. Figure 8 The state shown.

[0191] When the battery pack is placed in the energy storage compartment, the locking part at the top of the battery pack corresponds to the locking tongue 6553 of the locking buckle. Under the downward pressure of the locking part at the top of the battery pack, the locking tongue 6553 overcomes the elastic force of the compression spring 6555 and moves inward. During the inward movement, the pressing member 673 in the arc protection unit is interfered with by the buckle body 6551 of the locking buckle moving inward. Under the pressure, the free end of the pressing member 673 moves around the connecting end in the forward direction. Rotate to the second state and press the trigger button of the micro switch 671 in the arc protection unit. The trigger button of the micro switch 671 retracts under pressure, changing from a natural state (e.g., naturally protruding) to a pressed state (e.g., retracted under pressure). The micro switch 671 then enters a closed state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is de-energized. At this time, the conductive terminals of the battery pack can contact the charging terminals of the energy storage compartment in the de-energized state. This forms a... Figure 9 The state shown.

[0192] Subsequently, after the battery pack is fully placed in the energy storage compartment, the locking latch 6553 moves outward under the elastic force of the compression spring 6555. During this outward movement, the latch body 6551 of the locking latch gradually releases its pressure on the pressing member 673 in the arc protection unit. The free end of the pressing member 673 gradually rotates in the opposite direction around the connecting end and returns to the first state. Correspondingly, the trigger button of the micro switch 671 in the arc protection unit also moves outward, changing from a pressed state (e.g., compressed inward) to a natural state (e.g., naturally protruding). The micro switch 671 turns to the open state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is energized. At this time, the battery pack can be charged through the charging terminal of the energy storage compartment and the conductive terminal of the battery pack. Figure 8 The state shown.

[0193] Correspondingly, when the battery pack placed in the energy storage compartment is removed, before removal, the locking tongue 6553 of the locking buckle protrudes from the surface of the energy storage compartment 65 under the elastic force of the compression spring 6555. The pressing member 673 in the arc protection unit does not interfere with the buckle body 6551 of the locking buckle and is in the first state. At this time, the micro switch 671 in the arc protection unit is in the natural state (e.g., naturally protruding), the micro switch 671 is in the open state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is in the energized state. Figure 8 The state shown.

[0194] When the battery pack placed in the energy storage compartment is removed, the unlocking switch linked to the locking mechanism is operated. When the unlocking switch is operated, it causes the latch body and locking tongue in the locking buckle to move inward. During the inward movement, the pressing member 673 in the arc protection unit is interfered with by the latch body 6551 of the locking buckle as it moves inward. Under pressure, the free end of the pressing member 673 rotates around the connecting end in the forward direction to the second state and presses the trigger button of the micro switch 671 in the arc protection unit. After being pressed, the trigger button of the micro switch 671 moves inward, changing from a natural state (e.g., naturally protruding) to a pressed state (e.g., compressed inward). The micro switch 671 turns into a closed state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is in a de-energized state. At this time, the conductive terminal of the battery pack can be disconnected from the charging terminal of the energy storage compartment in the de-energized state, that is, the battery pack can be removed from the energy storage compartment. Figure 9 The state shown.

[0195] Subsequently, after the battery pack is completely removed from the energy storage compartment, the locking latch 6553 moves outward under the elastic force of the compression spring 6555. During this outward movement, the latch body 6551 of the locking latch gradually releases its pressure on the pressing member 673 in the arc protection unit. The free end of the pressing member 673 gradually rotates in the opposite direction around the connecting end and returns to the first state. Correspondingly, the trigger button of the micro switch 671 in the arc protection unit also moves outward, changing from a pressed state (e.g., compressed inward) to a natural state (e.g., naturally protruding). The micro switch 671 turns to the open state, and the charging terminal associated with the micro switch 671 in the energy storage compartment is energized. Figure 8 The state shown.

[0196] In some embodiments, the arc protection unit may include a Hall effect device associated with a charging terminal within the energy storage compartment. The Hall effect device may be located adjacent to a locking latch of the locking mechanism. When the locking mechanism is in a first position, the Hall effect device is in a first state, and the charging terminal is energized; when the locking mechanism is in a second position, the Hall effect device is in a second state, and the charging terminal is de-energized.

[0197] In some embodiments, when the locking latch of the locking mechanism is in a first position (e.g., when the latch's tongue is protruding), the Hall effect device is in an open state, and the charging terminal associated with the Hall effect device in the energy storage compartment is energized. When the locking latch of the locking mechanism is in a second position (e.g., when the latch's tongue is retracted), the Hall effect device is in a closed state, and the charging terminal associated with the Hall effect device in the energy storage compartment is de-energized. Alternatively, in some embodiments, when the locking latch of the locking mechanism is in a first position (e.g., when the latch's tongue is protruding), the Hall effect device is in a closed state, and the charging terminal associated with the Hall effect device in the energy storage compartment is de-energized. When the locking latch of the locking mechanism is in a second position (e.g., when the latch's tongue is retracted), the Hall effect device is in an open state, and the charging terminal associated with the Hall effect device in the energy storage compartment is energized.

[0198] In some embodiments, the energy conversion device further includes a heat dissipation structure for each energy storage compartment, which is used to dissipate heat from the battery pack housed in the corresponding energy storage compartment during the charging process.

[0199] In some embodiments, the heat dissipation structure includes: a heat dissipation cavity, a drainage port, a heat dissipation outlet, and a cooling fan.

[0200] Please see Figure 10 Displayed as Figure 7 A schematic diagram of the structure of the medium-energy conversion device after removing part of the casing.

[0201] Combination Figure 7 and Figure 10 The heat dissipation structure includes: a heat dissipation cavity 681, a drain port 683, a heat dissipation port 685, and a cooling fan 687.

[0202] The heat dissipation cavity 681 is disposed within the device body 61 and is positioned directly opposite the energy storage chamber 65. In some embodiments, the heat dissipation cavity 681 may be a semi-open space or an enclosed space formed by multiple outer shells, and the outer shells may be made of flame-retardant ABS plastic.

[0203] A drain port 683 is disposed on the surface of the heat dissipation cavity 681 and communicates with the energy storage compartment. In some embodiments, the drain port 683 corresponds to the heat dissipation port 802 of the battery pack 80 housed in the energy storage compartment 65. Exemplarily, the size of the drain port 683 is substantially the same as the size of the heat dissipation port 802 of the battery pack 80, and the drain port may include a drain plate and drain holes disposed regularly or irregularly on the drain plate.

[0204] The heat dissipation vent 685 is located beside the heat dissipation cavity 681. Thus, when the battery pack charging base 6 supports wall mounting, the heat dissipation vent located beside the heat dissipation cavity can still operate normally.

[0205] A cooling fan 687 is disposed within the heat dissipation cavity 681, which can accelerate the flow of air and drive the airflow within the heat dissipation cavity 681 from the inlet 683 to the heat dissipation outlet 685. For example, the cooling fan 687 is positioned corresponding to the inlet 683, and can directly drive the flow of air introduced from the inlet. For example, the cooling fan 687 can be a centrifugal fan. To better improve the heat dissipation performance of the heat dissipation device within a limited space, the blade parameters, housing curve shape, motor design parameters, etc., of the centrifugal fan in the heat dissipation structure can be optimized to achieve a reasonable combination.

[0206] Of course, in some embodiments, the heat dissipation structure may also include heat dissipation fins.

[0207] In another embodiment of the charging system provided in this disclosure, the energy conversion device in the charging system further includes a first power output interface, which is disposed on the surface of the device body and electrically connected to the power conversion unit for charging based on an external battery pack electrically connected to it.

Figure 12 As shown, the energy conversion device is implemented as a battery pack charging stand, which includes: a device body 61, an energy input interface or energy input connector, at least one energy storage compartment, an energy conversion unit, and a second energy output interface 693.

[0220] The device body 61 has a housing made of flame-retardant ABS plastic, in which a first receiving space can be formed. A charging circuit board can be built into the first receiving space. The charging circuit board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions.

The battery pack charging base 6 is electrically connected to the power adapter 1 via a power input interface or power input connector. The power adapter 1 draws power from the mains and charges the battery pack configured on the electrically connected external electrical device, i.e., the battery pack 503 configured on the chainsaw 502 or the battery pack 505 configured on the garden hair dryer 504, through the battery pack charging base 6.

[0230] Please see Figure 13The diagram shown is a structural schematic of a charging system according to another embodiment of the present disclosure. Figure 13 As shown, the energy conversion device is implemented as a battery pack charging stand, which includes: a device body 61, an energy input interface or energy input connector, at least one energy storage compartment, an energy conversion unit, and a second energy output interface 693.

[0231] The device body 61 has a housing made of flame-retardant ABS plastic, in which a first receiving space can be formed. A charging circuit board can be built into the first receiving space. The charging circuit board includes a printed circuit board (e.g., a PCBA circuit board), on which various components are arranged to form different functions. In some embodiments, a power conversion unit can be provided on the charging circuit board.

[0232] An electrical input interface or electrical input connector is provided on the surface of the device body 61.

[0233] At least one energy storage compartment is provided for accommodating the battery pack 80. In some embodiments, the at least one energy storage compartment may be located on the front side of the housing of the device body 61, and may be a semi-open or open structure design, thereby allowing the battery pack 80 to be conveniently placed and removed into the corresponding energy storage compartment. In some embodiments, the at least one energy storage compartment may be built into the housing of the device body 61.

[0234] The energy storage compartment is equipped with a charging terminal for forming an electrical connection with the conductive terminals of the battery pack it houses. In some embodiments, one energy storage compartment can house one battery pack, in which case the energy storage compartment is equipped with a charging terminal, and the conductive terminals of the housed battery pack are electrically connected to the charging terminal. In some embodiments, one energy storage compartment can house two or more battery packs, in which case the energy storage compartment is equipped with two or more charging terminals, and the conductive terminals of the two or more housed battery packs can be electrically connected to the corresponding charging terminals.

[0235] In some embodiments, the battery pack may include at least one of a first power battery and a second power battery. Therefore, when the energy storage compartment contains the first power battery, the second power battery, or a combination of the first and second power batteries, they can be charged.

[0237] The external electrical equipment may be equipped with a battery pack, which includes pouch batteries, conventional battery packs, or other types of rechargeable batteries.

[0238] For example, the external power equipment includes portable electric gardening equipment, such as a backpack lawnmower, chainsaw, garden blower, etc. Figure 13 The chainsaw 506 and garden blower 508 are shown.

[0239] Using the second power output interface 693, an external electrical device can be electrically connected via a cable with a plug that matches the second power output interface 693 to output power to the external electrical device for its use.

[0240] When using the charging system provided in this embodiment, the battery pack 80 to be charged is placed in the energy storage compartment of the battery pack charging base 6. The conductive terminals of the battery pack are electrically connected to the charging terminals in the energy storage compartment. The power input connector 13 of the power adapter 1 can be connected to AC power to input electrical energy. The power output interface of the power adapter is electrically connected to the power input interface of the battery pack charging base 6 through the charging cable 200, so that the power adapter 1 and the battery pack charging base 6 are electrically connected. In this way, the power adapter 1 receives the AC power and outputs it to the electrically connected battery pack charging base 6 through a certain conversion to charge the battery pack 80 in its energy storage compartment. Subsequently, after the battery pack 80 has finished charging, the battery pack charging base 6 is disconnected from the power adapter 1, and an external power-consuming device (e.g., a chainsaw 506 or a garden hair dryer 508) that needs power is electrically connected to the second power output interface 693 of the battery pack charging base 6 through a cable. Figure 14 As shown, the battery pack charging base 6 equipped with the battery pack 80 can be used as a backpack power source. The battery pack 80 in the battery pack charging base 6 outputs electrical energy to an electrically connected external DC wired power device (e.g., a chainsaw 506 or a garden blower 508) for its operation.

[0241] In summary, in at least some embodiments of this specification, the power adapter surface is configured with at least one power output interface, which is pluggable to a charging cable. The end of the charging cable furthest from the power adapter can be configured as an external power device or energy conversion device, meaning that the power adapter can be used to charge various devices by changing different charging cables, thereby broadening the applicability of the power adapter.

[0242] For example, in some optional embodiments, the power adapter supplies power to at least one of the gardening tools, such as an electric gardening vehicle, an electric garden blower, or an electric chainsaw, by changing the charging cable; specifically, in some optional embodiments, the gardening tools, such as the electric gardening vehicle, electric garden blower, electric snowplow, or electric chainsaw, are equipped with battery packs, and the power adapter charges the battery packs of the aforementioned gardening tools. In another optional embodiment, the charging cable of the power adapter is long enough to cover part of the working area of ​​the gardening tool, in which case the gardening tool may not be equipped with a battery pack and is directly powered by the power adapter.

[0243] In another optional embodiment, the power adapter charges the battery pack charging dock or battery pack charging device by changing the charging cable, or even charges the energy storage unit that has battery cells integrated in part.

[0244] In this specification, the power adapter has a pluggable power output interface for a charging cable, the other end of which is connected to an external electrical device or energy conversion device; and the external electrical device or energy conversion device, based on the electrical connection, outputs electrical energy through the charging cable. This allows a single power adapter to supply power to different external electrical devices or energy conversion devices.

[0245] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
