Description of the Invention: [Technical Field] The present invention relates to an electronic device, and more particularly to a charging device. [Prior Art] Parts that store energy are important to our lives, such as rechargeable batteries in portable electronic devices. Parts that store electrical energy affect the performance of the electronic device and the operating time. ® In general, rechargeable batteries have a common electrochemical property, that is, the chemical reaction is a reversible reaction, and the power can be converted into chemical energy by an external power source to restore the discharged battery to its original state. Conversely, if the chemical reaction is irreversible, the battery cannot be charged, as is the case with dry batteries. However, if several batteries are charged in series, precautions are required. Because of changes in temperature or battery life, there is a slight difference in voltage across the battery; moreover, the more the battery is connected in series, the greater the difference in terminal voltage. However, the current supplied by the charger to each battery is the same, so it is conceivable that some batteries are fully charged, while other batteries are not fully charged, or are overcharged in low temperature environments, not in high temperature environments. Fully full. In view of this, how to charge the battery more efficiently becomes an important issue.

The plurality of charging modules are electrically connected to the plurality of batteries one-to-one, wherein the batteries are connected in series with each other. The charge pump draws power from the power source. The switch switching circuit can electrically connect the plurality of charging modules to the charge pump. In the charging module in which the charge is electrically connected, the storage circuit can receive power from the charge pump, and then the charging circuit can charge the power received by the storage circuit to the battery electrically connected to the charging module. In this way, the charging device can separately charge a single battery to achieve the effect of fast charging. The above description and the following embodiments will be described in detail in the various embodiments, and the invention will be further explained. [Embodiment] In order to make the description of the present invention more complete and complete, reference is made to the accompanying drawings and the accompanying drawings. On the other hand, well-known elements are not described in the embodiments to avoid unnecessarily limiting the invention. 0 The technical aspect of the present invention is a charging device that can be applied to a charger or widely used in related technical aspects. It is worth mentioning that the charging device of the technical aspect can have the effect of fast charging, and can also automatically adjust the saturation voltage and current during charging according to the ambient temperature. The specific embodiment of the charging device will be described below with reference to Fig. 1. Referring to Fig. 1, a first block diagram is a block diagram of a charging apparatus in accordance with an embodiment of the present invention. As shown, the charging device can include a charge pump 210, a switch switching circuit 220, and a plurality of charging modules 110, 120, 130, wherein each charging module can include a charging circuit and a storage circuit. In the embodiment of the present embodiment, the charging module 110 can include a charging circuit and a storage circuit ι 2; the charging module 120 can include a charging circuit 24 and a storage circuit 122; the charging module 130 can include a charging circuit 134 and Power storage circuit 132. Structurally, the plurality of charging modules 11A, 120, and 130 are electrically connected to the plurality of batteries 119, 129, and 139 one-to-one. In this embodiment, the charging module 11 is electrically connected to the battery 119; the charging module 12 is electrically connected to the battery 129; and the charging module 130 is electrically connected to the battery 139. Further, these batteries H9, 129, 139 may be connected in series to each other. 0 Power supply 2〇〇 provides power when in use. The charge pump 210 can draw power from the power source 2〇〇. The switch switching circuit 220 can electrically connect one of the plurality of charging modules 11 〇, 12 〇, 13 至 to the charge pump 21 。. The charge pump 210 described above may include a capacitor to facilitate storage of power. However, the present invention is not limited thereto, and the charge pump 21A may also include various other electronic components, which should be selected by those skilled in the art as needed. In this embodiment, the switch switching circuit 22 can electrically connect the charging module 11 to the charge pump 210, and the remaining charging modules 12A, 13A are electrically isolated from the charge pump 21. When the charging module 110 is electrically connected to the charge pump 21, the storage circuit 112 can receive power from the charge pump 210, and the charging circuit 114 can charge the power received by the storage circuit to the battery 119. Thus, the charging module 11 can charge the battery 119. Alternatively, the switch switching circuit 220 can electrically connect the charging module 12 to the charge pump 21G, and the remaining charging modules 11(), 13() are electrically isolated from the charge pump (4). When the electrical module 120 is electrically connected to the charge 210, the storage circuit 122 can receive power from the charge multiplier 210. The charging circuit 124 can charge the power received by the power circuit 122 to the battery 129. In this way, the charging module 12 can enter the battery 129 into the 201027876 or the switch switching circuit 220 can electrically connect the charging module 13 to the charge pump 210, and the remaining charging modules 110, 120 are electrically isolated from the charge pump 21 . When the charging module 130 is electrically connected to the charge pump 210, the storage circuit 132 can receive power from the charge pump 210. The charging circuit 134 can charge the power received by the storage circuit 132 to the battery 139. Thus, the charging module 13 can charge the battery 139. In summary, after the charge pump 210 receives power from the power source 2, if any one of the batteries is to be charged, the switch switching circuit 22 can connect the charge pump 21 to the corresponding charging module of the battery. The battery is electrically connected to its corresponding charging module. As such, the charging device can charge a single battery separately. For example, when the battery 119 is to be charged, the switch switching circuit 22 can electrically connect the charge pump 210 to the charging module, and the charging module can charge the battery ^9. As for the above power source 200, it can be a DC power source. The power supply can supply more than 5 volts of power. More specifically, the power supply of the power source 2 范围 has a range of 5 volts or more and 4 volts or less. Additionally, the total voltage of the plurality of batteries (e.g., batteries 119, 129, 139) connected in series with each other is less than about 1000 volts. For example, the power supply 2 〇〇 can supply a DC power of about 12 volts, and the battery string has a total voltage of about 9 volts. Thus, the charging device can charge the high voltage battery string at a low voltage. Each of the above-described power storage circuits (e.g., power storage circuit 112, power storage circuit 122, or power storage circuit 132) may include a capacitor to facilitate storage of power. However, the present invention is not limited to the invention. Each of the storage circuits may also include other various components, and those skilled in the art should select the flexibility at that time. The charging circuit (for example, the charging circuit 114, 124, 134) may be a constant voltage/current charging circuit 'to facilitate charging the power received by the storage circuit to the battery stably to the battery', that is, the constant voltage/current charging circuit to the battery. The voltage and current of the output power are stable. In practice, if the battery charging voltage is too high or too low, it will hurt the battery. If the charging voltage is too high, even if the battery is saturated, it will force a large current into the battery. This large current will decompose the electrolyte in the battery and shorten the battery life. Conversely, if the charging voltage is too low, the battery is not yet Before charging, there is no charging current, and the battery capacity is reduced. The above batteries 119, 129, and 139 may be rechargeable batteries such as a nickel recording battery, a nickel hydrogen battery, or a lithium battery. Nickel-cadmium batteries are low in price but have a memory effect and toxicity. Nickel-metal hydride batteries charge quickly, but have high temperature characteristics, high self-discharge rate, and slight memory effects. Lithium batteries have the characteristics of fast charging, no memory effect, stable discharge characteristics, etc., but they are prone to short-circuit and explosion, and are not interchangeable with other batteries. It should be understood that due to the high risk of lithium batteries, the charging process does not generate heat. When overcharge occurs, lithium ions are reduced to dendritic lithium metal, and the lithium battery electrolyte is an organic solvent. Crystallization may cause positive The insulating material between the negative electrode sheets is pierced, and a short-circuit phenomenon occurs, which may cause high-temperature burning or explosion. The electrolyte may combine with the moisture in the air to generate harmful gases. When the lithium battery is broken or leaking, do not Use, should be recycled as soon as possible. Of course, the above-mentioned nickel-cadmium battery, nickel-hydrogen battery and lithium battery are merely examples, and are not intended to limit the present invention. The specific implementation of the elastic selection battery 119 '129, 139 should be determined by those skilled in the art according to actual needs. the way. Further, although only three batteries 119, 129, and 139 of Fig. 1 are shown, the present invention is not limited thereto. Regarding the number of batteries and charging modules, in practice, the number of batteries connected in series can be increased or decreased according to actual needs, and the number of charging modules can be determined by the number of batteries connected in series. For example, if there are 100 batteries connected in series, correspondingly, 100 charging modules can be electrically connected to the 100 batteries. Please continue to refer to Figure 1. Regarding the plurality of charging modules 110, 120, 130, 201027876, each of the charging modules may include a voltage value monitoring circuit. In this embodiment, the charging module 110 can include a voltage value monitoring circuit 116; the charging module 12 can include a voltage value monitoring circuit 126; and the charging module 130 can include a voltage value monitoring circuit 136. In use, the voltage value monitoring circuit can detect whether the voltage of the battery electrically connected to the charging module is lower than a predetermined voltage. In this embodiment, the voltage value monitoring circuit 116 can detect whether the voltage of the battery 119 is lower than a predetermined voltage; the voltage value monitoring circuit 126 can detect whether the voltage of the battery 129 is lower than a predetermined voltage; the electric grinding value numerical monitoring circuit U6 can It is detected whether the voltage of the battery 139 is lower than a predetermined voltage. In application, if the voltage of the battery is lower than the predetermined voltage, it means that the battery needs to be charged. Regarding the above-described predetermined voltage state, the predetermined voltage can be set in accordance with the rated voltage and temperature characteristics of the battery. In this embodiment, the predetermined voltage may be set to 30% to 70% of the rated voltage of the battery and further adjusted by 1 °/ depending on the ambient temperature. ~ 5%, but this does not limit the invention, and those skilled in the art should consider the need to 'elastically select a predetermined voltage setting method at the time. Please continue to refer to Figure 1. As shown in the figure, the charging device may further include a microprocessor 230. In the embodiment, if the voltage of the battery 119 electrically connected to the charging module 11 is lower than a predetermined voltage, the microprocessor 23 may The command switch switching circuit 220 electrically connects the charging module 110 to the charge pump 21A. As such, the power storage circuit 112 of the charging module 110 can receive power from the charge pump 21A. The charging circuit 114 can charge the power received by the storage circuit 112 to the battery 119. Thus, the charging module 110 can charge the battery U9. Alternatively, if the voltage of the battery 129 electrically connected to the charging module 120 is lower than a predetermined voltage, the microprocessor 230 may instruct the switch switching circuit 22 to electrically connect the charging module 120 to the charge pump 21A. As such, the charging module 12 can store power from the charge pump 210. The charging circuit 124 can charge the power received by the storage circuit 122 to the battery 129. As such, the charging module 120 can charge the battery 129. Alternatively, if the voltage of the battery 139 electrically connected to the charging module 130 is lower than a predetermined voltage, the microprocessor 23 can command the switching circuit 22 to electrically connect the charging module 130 to the charge pump 21A. Thus, the storage circuit 132 of the charging module 13 can receive power from the charge pump 21A. The charging circuit 134 can charge the power received by the storage circuit 132 to the battery 139. Thus, the charging module 13 can charge the battery 139. As described above, if the voltage of the battery is lower than the predetermined voltage, it means that the battery needs to be charged. Therefore, after the charge pump 21 receives power from the power source 200, if the battery is to be charged with a voltage lower than the predetermined voltage, the switch switching circuit 22 can electrically connect the charge pump 210 to the corresponding charging module of the battery. The battery is electrically connected to its corresponding charging module. For example, if the microprocessor 230 can command the switch switching circuit 220 to electrically connect the charge pump 210 to the charging module 11 when the battery 1 1 9 is charged, the charging module 11 can charge the battery 119. . On the other hand, in the embodiment, in a state where the charging module 11 is electrically connected to the charge pump 21, if the storage circuit 112 of the charging module 11 receives the power, the microprocessor 230 can command The switch switching circuit 220 electrically isolates the charge module 210 from the charging module 11; and the microprocessor 230 can instruct the switch switching circuit 220 to electrically connect other charging modules (such as the charging module 120 or the charging module π〇). To the charge pump 210. The charging circuit of the other charging module (for example, the storage circuit 122 or the storage circuit 132) can also obtain power from the charge pump 21 while the charging circuit 114 charges the power received by the storage circuit 112 to the battery 119. . Alternatively, in a state where the charging module 120 is electrically connected to the charge pump 21, 201027876, after the power storage circuit 122 of the charging module 120 receives the power, the microprocessor 23 can command the switching circuit 220 to charge the module. 12 〇 electrically isolates the charge pump 210 , and the microprocessor 230 can instruct the switch switching circuit 220 to electrically connect other charging modules (eg, the charging module 110 or the charging module 13 〇 ) to the charge pump 210 . The charging circuit of the other charging module (for example, the storage circuit 112 or the storage circuit 132) can also be obtained from the charge pump 21 while charging the power received by the storage circuit 122 to the battery 129. electric power. Alternatively, in a state where the charging module 130 is electrically connected to the charge pump 210, after the power storage circuit 132 of the right charging module 接收0 receives the power, the microprocessor 23 can command the switching circuit 22 to charge the module. 13〇 electrically isolates the charge pump 210, and the microprocessor 230 can instruct the switch switching circuit 22 to electrically connect other charging modules (eg, the charging module 1丨〇 or the charging module 丨2〇) to the charge pump 210. . Therefore, while the charging circuit 134 charges the power received by the storage circuit 132 to the battery 139, the storage circuit of the other charging module (for example, the storage circuit 112 or the storage circuit 122) can also obtain power from the charge pump 21 . In summary, after the charge pump 21 receives power from the power source 2, the microprocessor 230 can instruct the switch switching circuit 22 to electrically connect a charging module to the charge pump 210, and then the charging module The storage circuit can receive power. After the power storage circuit of the charging module receives the power, the microprocessor 23 can command the switch switching circuit 220 to electrically isolate the charge system 21 from the charging module. And the charge 21 〇 can regain power from the power source 200. The microprocessor 230 can instruct the switch switching circuit 22 to electrically connect another charging module to the charge fruit 210 after the charge pump 2 i 取得 takes power from the power supply. Therefore, while the charging circuit of one charging module charges power to the battery 139, the storage circuit of the other charging module can also obtain power by itself. In this way, the charging device not only can separately charge a single battery holder, but also saves charging time and achieves the effect of fast charging. 201027876 In practice, when the power supply 200 charges the charge pump 210, the capacitor of the charge 2i〇 is charged quickly; when the charge pump 210 charges the charging module, the capacitor of the storage circuit is also charged quickly, and when the battery is being charged, the battery is charged. Electricity should be converted to chemical energy, so the battery takes a long time to charge. In the present embodiment, if the power supply 200 charges the charge pump 210 for about 1 unit time, the charge pump 210 charges the charging module for about a unit time. However, the charging module charges the battery for about 1 unit time. In the control experiment, the charge pump 210 directly charges the battery for about 1 unit time. For example, while the charging module 110 charges the battery 119, the charge pump 210 can separately charge the charging module 12, and then the charging module 120 can charge the battery 129. In the control experiment, if the battery 119 is directly charged by the charge pump 2, it takes about 10 units of time. Moreover, it is necessary to wait for the battery Π9 to be charged and the charge pump 21 〇 to charge the battery 129 separately. In contrast, the charging device of the present technology can achieve the effect of fast charging. Please continue to refer to Figure 1. As shown, the above charging device may include a plurality of temperature sensors 117, 127, 137. _ Structurally, a plurality of temperature sensors 117, 127, 137 may be attached to the plurality of batteries 119, 129, 139, respectively; or a plurality of temperature sensors ι 17, 127, 137 may be embedded in the plurality of batteries 119, 129, respectively. In 139, those skilled in the art should consider the need to flexibly choose at that time. In use, a plurality of temperature sensors 117, 127, 137 sense the temperatures of the plurality of cells 119, 129, 139, respectively. Please continue to refer to Figure 1. As shown, each charging module can include a temperature monitoring circuit. In this embodiment, the charging module 114 can include a temperature monitoring circuit U8; the charging module 124 can include a temperature monitoring circuit 128; and the charging module 134 can include a temperature monitoring circuit 138. 11 201027876 In use, each temperature sensor 117, 127, 137 can provide a temperature value for each of the batteries 119, 129, 139 to temperature monitoring circuits 118, 128, 138, respectively. The temperature monitoring circuits 118, 128, 138 can each adjust the saturation voltage and current at which the charging circuits U4, 129, 139 charge the batteries U9, 129, 139 based on the temperature of the batteries U9, 129, 139. In practice, the temperature monitoring circuits 118, 128, 138 can each determine whether the temperature of the batteries 119, 129, 139 during charging is abnormal, and adjust the saturation voltage and current for charging the battery according to the ambient temperature. φ Regarding the above-mentioned saturation voltage and current, it is practical to adjust the saturation voltage and current according to the rated voltage, rated current and temperature characteristics of the battery. In the present embodiment, 'If the low-temperature ring charging time means that the saturation voltage and current for charging the battery need to be lowered', if the charging time in the high-temperature ring means that the saturation voltage and current for charging the battery need to be increased, familiar with this. The craftsman should flexibly choose the adjustment method of saturation voltage and current as needed.
