Abstract
Description
Technical Field
[0001] The present invention relates to the field of charging, and in particular to a method for operating an emergency charging device and an emergency charging device. Background Art
[0002] Figure 1 1 is a schematic diagram of a method of operating a charging device in the prior art. When a plurality of batteries 100, 102, 104 to be charged are connected to the multi-channel charger 10, and the multi-channel charger 10 is coupled to an AC-DC transformer 106, and the AC-DC transformer 106 is coupled to an external AC power source, the multi-channel charger 10 can charge the batteries 100, 102, 104 to be charged. Assuming that the number of batteries 100, 102, 104 to be charged coupled to the multi-channel charger 10 is 3, and the power levels are 40%, 30%, and 20% respectively, the multi-channel charger 10 will first charge the battery 100 to be charged with 40% power, and then charge the battery 102 to be charged with 30% power after it is fully charged, and then charge the battery 104 to be charged with 20% power after it is fully charged. In this way, the three batteries 100, 102, and 104 to be charged can be fully charged. However, when charging is needed and there is no external AC power source, or the site is not convenient for using the AC-DC converter 106, then the three batteries 100, 102, 104 with 40%, 30%, and 20% of charge respectively cannot provide a complete use of the drone or other device.
[0003] Therefore, it is necessary to design a new type of emergency charging device and a method for operating the emergency charging device to overcome the above-mentioned defects. Summary of the invention

[0030] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.
[0031] Certain words are used in the specification and claims to refer to specific components. Those with ordinary knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".
[0032] Figure 2 2 is a schematic diagram of an embodiment of an emergency charging device 200. The emergency charging device 200 includes a multi-channel charger 202, a mutual charging switch 204, and a battery group to be charged 206. The battery group to be charged 206 is connected to the multi-channel charger 202 to wait for charging, and the multi-channel charger 202 is coupled with the mutual charging switch 204 to activate the mutual charging function. After the mutual charging function is activated, multiple batteries with power less than a preset threshold are set as a target battery group, and then the multi-channel charger 202 charges and discharges the target battery group.
[0033] Initially, the battery group 206 to be charged is connected to the multi-channel charger 202. When the mutual charging switch 204 is triggered, multiple batteries with power lower than the preset threshold are set as the target battery group, and a battery with the highest power in the target battery group is selected as the charging battery, and a battery with a power lower than the charging battery in the target battery group is selected as the discharging battery, and the power of the discharging battery is charged to the charging battery. The preset threshold can be 50% of the power or a voltage of 3.7V, but is not limited thereto. When the discharging battery is fully discharged, if the charging battery is not fully charged, a battery other than the fully charged battery and the charging battery in the target battery group can be selected again as the discharging battery. When the charging battery is fully charged, the battery with the highest power other than the fully charged battery in the target battery group can be selected again as the charging battery, and another battery other than the fully charged battery and the charging battery in the target battery group can be selected as the discharging battery. By repeating this cycle, the power of all batteries to be charged can be concentrated on a few rechargeable batteries, allowing users to use batteries with fuller power.
[0034] It should be noted that, in one embodiment, when the multi-channel charger 202 is connected to the battery group 206 to be charged and is coupled to an external power charger, and the external power charger provides external power to the multi-channel charger 10, the mutual charging switch 204 of the emergency charging device 200 is disabled, and the multi-channel charger 10 preferentially charges a battery with the highest power in the battery group 206 to be charged, and after fully charged, charges the battery with the highest power in the battery group 206 to be charged except for the fully charged battery, and repeats this cycle to fully charge all the batteries to be charged. In addition, in another embodiment, when the multi-channel charger 202 is connected to the battery group 206 to be charged and the mutual charging function is activated, the multi-channel charger 202 is connected to the external power charger at any time after the mutual charging function is activated, and the external power charger provides external power to the multi-channel charger 10, then the mutual charging function of the emergency charging device 200 is interrupted, and the external power charger provides external power to the multi-channel charger 10. The multi-channel charger 10 preferentially charges a battery with the highest power in the battery group 206 to be charged, and after it is fully charged, it charges the battery with the highest power in the battery group 206 to be charged except for the fully charged battery. This cycle is repeated, and all the batteries to be charged can be fully charged.
[0035] Figure 3 is a schematic diagram of an embodiment of operating the emergency charging device 200 . Figure 3The multi-channel charger 202 is connected to three batteries to be charged 300, 302, 304, and there is no external power supply. At this time, when the mutual charging switch 204 of the emergency charging device 200 is pressed, if the preset threshold is higher than 40%, such as 50%, the three batteries with power levels of 40%, 30%, and 20% respectively will all be selected into the target battery group 310, among which the battery 300 with the highest power level of 40% can be selected as the charging battery, that is, the object of this emergency charging, and the battery 302 with the second highest power level of 30% can be selected as the discharging battery, and the multi-channel charger 202 will charge the power of the battery 302 to the battery 300. When the 30% power level is completely discharged, the battery 302 can no longer discharge. At this time, the battery with the second highest power level other than the fully charged battery can be selected as the new discharging battery, that is, the battery 304 with the power level of 20% can be selected as the discharging battery, and then the 20% power level is charged from the discharging battery 304 to the charging battery 300. Finally, the power levels of the three batteries on the multi-channel charger are 90%, 0%, and 0% respectively, thus achieving the goal of concentrating the power on a few batteries.
[0036] Figure 4 is a schematic diagram of another embodiment of operating the emergency charging device 200 . Figure 4 The multi-channel charger 202 is connected to five batteries 402, 404, 406, 408, 410 to be charged, and there is no external power supply. At this time, when the mutual charging switch 204 of the emergency charging device 200 is pressed, if the preset threshold is 70%, all batteries 404, 406, 408, 410 except the battery 402 with 80% power will be selected into the target battery group 420, among which the battery 404 with the highest power of 60% can be selected as the charging battery, that is, the object of the emergency charging, and the battery 406 with the second highest power of 40% can be selected as the discharging battery, and the multi-channel charger 202 will charge the power of the battery 406 to the battery 404. When the battery 404 is fully charged (e.g., the power level is 100% or slightly lower than 100%), the multi-channel charger 202 selects a battery 408 with the highest power level from the fully charged batteries in the target battery group 420 as a new charging battery, and since the battery 406 has been fully discharged (e.g., the power level is 0% or slightly higher than 0%), the multi-channel charger 202 selects a battery from the fully charged batteries and the charging batteries in the target battery group 420 as a discharging battery, i.e., the 30% battery 410. Finally, the multi-channel charger 202 charges the battery 410 to the battery 408, so that the power levels of all the batteries 402, 404, 406, 408, and 410 are 80%, 100%, 0%, 65%, and 0%, respectively, so as to achieve the purpose of concentrating power on a few batteries.
[0037] Figure 5 is a flow chart of a method 500 of operating an emergency charging device.
[0038] Step S502: after the mutual charging switch 204 is triggered, a plurality of batteries whose power levels are lower than a preset threshold are set as a target battery group;
[0039] Step S504: selecting a battery with the highest power in the target battery group as a charging battery;
[0040] Step S506: selecting a battery with a lower power than the charging battery from the target battery group as a discharging battery;
[0041] Step S508: charging the power of the discharge battery into the rechargeable battery.
[0042] In step S502, the preset threshold may be 50% of the power or 3.7V voltage, but is not limited thereto. In step S506, the discharge battery may be the battery with the second highest power in the target battery group (i.e., the battery with the highest power except the above-mentioned rechargeable battery). After step S508, when the discharge battery has completed discharging and the rechargeable battery has not been fully charged, another battery may be selected in the target battery group as another discharge battery and the power of the other discharge battery may be charged to the rechargeable battery. When the rechargeable battery is fully charged, a battery with the highest power except the fully charged battery may be selected in the target battery group as another rechargeable battery and the power of the discharge battery may be charged to the other rechargeable battery.
[0043] The emergency charging device of the present invention has a simple structure and a low manufacturing cost. Through the emergency charging device of the present invention, an emergency charging method can be implemented when the user cannot use an external power supply to charge, so that the target battery group with low remaining power can generate at least one high-power battery for use.
[0044] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
