Description

Rechargeable battery

The present invention relates to batteries; in particular to a rechargeable battery.

The dry batteries sold on the market cannot be used after they have been used up and need to be recycled, which leads to environmental problems. Rechargeable batteries can be recharged and reused, which is more environmentally friendly than dry batteries. There are two common types of rechargeable batteries on the market: nickel-metal hydride batteries and lithium batteries. Nickel-metal hydride batteries are cheaper but have a memory effect and a longer charging time. Lithium batteries are more expensive but have no memory effect and a shorter charging time than nickel-metal hydride batteries. However, lithium batteries are prone to combustion risks due to collisions.

When charging a conventional rechargeable battery, a dedicated charger is required to inject the charging energy into the positive and negative electrodes of the rechargeable battery to restore the chemical substances inside the rechargeable battery. Rechargeable batteries take a long time to charge, usually taking several hours to fully charge, so there are still inconveniences in use.

In view of this, the purpose of the present invention is to provide a rechargeable battery that can be easily charged.

In view of this, the purpose of the present invention is to provide a rechargeable battery that can be charged quickly.

In order to achieve the above-mentioned purpose, the present invention provides a rechargeable battery, which includes a housing, a power receiving module, a charging management module, a storage capacitor, a positive electrode and a negative electrode. Among them, the power receiving module is used to output an input power; the charging management module is arranged in the outer shell, the charging management module is electrically connected to the power receiving module and receives the input power and converts it into a charging power; the storage capacitor is a super capacitor or a lithium ion capacitor and is arranged in the outer shell, the storage capacitor is electrically connected to the charging management module, and receives the charging power for charging; the positive electrode and the negative electrode are arranged in the outer shell and a part of them is exposed outside the outer shell, the positive electrode and the negative electrode are electrically connected to the storage capacitor for outputting an output power.

The effect of the present invention is that the rechargeable battery itself has a power receiving module and a charging management module, and can be conveniently charged without the need for a traditional rechargeable battery charger. In addition, due to the fast charging characteristics of the storage capacitor, the storage capacitor can be fully charged in a short time, allowing the rechargeable battery to be used again in a short time.

In order to explain the present invention more clearly, a preferred embodiment is described in detail with reference to the drawings. Please refer to FIG. 1 to FIG. 4 , which are a rechargeable battery 1 of the first preferred embodiment of the present invention. The rechargeable battery 1 has at least a size that meets the International Electrotechnical Commission (IEC) dry battery specifications, such as LR20, LR14, 6LR61, 6F22, 4LR61, LR6, LR03, LR1, LR8D425, 4R25Y, 4LR25X, 4LR25-2, or a size that meets the lithium-ion battery specifications, such as cylindrical lithium-ion batteries 26650/21700/18650/17670/18500/18350/17500/16340/14500/10440, and 3V CR2032, CR2025 and 12V 23A batteries. Preferably, the voltage and/or power can also meet the above specifications. The above specifications are only given as examples and are not intended to limit the present invention. In this embodiment, the size of the rechargeable battery 1 is LR6 (i.e., AA battery, or No. 3 battery) as an example.

The rechargeable battery 1 includes a housing 10, a positive electrode 12, a negative electrode 14, a power receiving module 16, a charging management module 20 and a storage capacitor 30.

The outer shell 10 can be formed by connecting two shells and has a accommodating space 10a inside. The accommodating space 10a is used to accommodate the power receiving module 16, the charging management module 20 and the storage capacitor 30. The shell can be made of plastic material and ultrasonic welding is used to form the outer shell 10.

The positive electrode 12 is disposed on the outer shell 10 and a portion thereof is exposed outside the outer shell 10. The negative electrode 14 is disposed on the outer shell 10 and a portion thereof is exposed outside the outer shell 10.

The power receiving module 16 is disposed in the housing 10, and the power receiving module 16 is used to receive an external power and output an input power Vin.

In this embodiment, the power receiving module 16 includes a connector 18, which is a female connector, such as a female connector of mini USB, micro USB, USB type-C, Lightning, etc. The connector 18 has at least one positive terminal 18a and at least one negative terminal 18b, and the connector 18 is connected to a male connector to receive external power. The voltage of the external power can be, for example, 4.8V~5.2V.

The charging management module 20 is disposed in the housing 10. The charging management module 20 is electrically connected to the power receiving module 16. The charging management module 20 receives the input power Vin and converts the input power Vin into a charging power Vc. In this embodiment, the charging management module 20 includes a step-down circuit 22 for stepping down the voltage of the input power Vin to form the charging power Vc. The step-down circuit 22 is composed of at least one diode D1. In this embodiment, two series-connected diodes D1 are used, and the forward conduction voltage of each diode D1 is 0.5V. The step-down circuit 22 is electrically connected to the connector 18. After the input power Vin is stepped down by the two diodes D1, the charging power Vc is formed. The power receiving module 16 receives external power and outputs the input power Vin. When the voltage of the input power Vin is greater than the voltage of the storage capacitor 30, the two diodes D1 are forward-conducted, and the storage capacitor 30 can be charged.

The storage capacitor 30 is disposed in the housing 10 and electrically connected to the charging management module 20. The storage capacitor 30 receives the charging power Vc for charging.

In this embodiment, the storage capacitor 30 is a supercapacitor or a lithium-ion capacitor, the capacitance value of the storage capacitor is above 40F, and the voltage value is 3.8V, but it is not limited to this. According to the size of the different accommodating space 10a, the capacitance value can also be above 200F or above 250F.

Since the storage capacitor 30 is a supercapacitor or a lithium-ion capacitor, it has the advantages of stable performance, short charging time, long cycle life, high power density, and good high and low temperature performance. The storage capacitor 30 has safety characteristics. There is no oxidation-reduction chemical reaction during the charging process, and there is no risk of combustion of traditional lithium batteries. The storage capacitor 30 also has environmental protection characteristics, without traditional heavy metal materials, and also contains cadmium, lead and mercury. The number of cycle charging reaches more than 100,000 times. It is also light in weight, has no battery memory effect, and has stable voltage. There will be no problem of battery leakage. Lithium-ion capacitors also have the characteristics of high instantaneous output current.

In order to protect the storage capacitor 30 from overcharging and/or overdischarging, in this embodiment, the charging management module 20 further includes a protection circuit 24, which is electrically connected to the storage capacitor 30. The protection circuit 24 detects the voltage of the charging power Vc. When the voltage of the charging power Vc is greater than a predetermined charging voltage, the protection circuit 24 blocks the charging power supplied to the storage capacitor 30. In this embodiment, the protection circuit 24 has a protection element 242, which can be implemented by ICs of model XB5532, AP9211, DW3 or equivalent. The protection element 242 is electrically connected to a positive terminal of the storage capacitor 30 via a resistor 244, and is electrically connected to a negative terminal of the storage capacitor 30. In a normal state, the negative end of the storage capacitor 30 is connected to the ground via the protection element 242. When the voltage of the charging power Vc is greater than the predetermined charging voltage, the protection element 242 blocks the connection between the negative end of the storage capacitor 30 and the ground, thereby blocking the charging power Vc supplied to the storage capacitor 30.

When the connector 18 is not connected to external power and the storage capacitor 30 does not receive the charging power Vc, the protection circuit 24 detects the voltage of the storage capacitor 30. When the voltage of the storage capacitor 30 is less than a predetermined discharge voltage, the protection circuit 24 blocks a discharge path of the storage capacitor 30. In this embodiment, the protection element 242 blocks the connection between the negative end of the storage capacitor 30 and the ground end to block the discharge path.

The charging management module 20 further includes a charging indication circuit 26 and a light-emitting element 28, and the light-emitting element 28 is an LED. When the charging indication circuit 26 detects that the voltage of the charging power Vc applied to the storage capacitor 30 is less than a predetermined voltage, the charging indication circuit 26 controls the light-emitting element 28 to emit light. When the charging indication circuit 26 detects that the voltage of the charging power Vc applied to the storage capacitor 30 reaches the predetermined voltage, the charging indication circuit 26 controls the light-emitting element 28 to stop emitting light.

In this embodiment, the charging indication circuit 26 includes a voltage detection element 262, a voltage divider circuit 264 and an inverter element 266. The detection end of the voltage detection element 262 is electrically connected to the positive end of the storage capacitor 30 via the voltage divider circuit 264. The output end of the voltage detection element 262 is electrically connected to the input end of the inverter element 266, the output end of the inverter element 266 is electrically connected to the light-emitting element 28, and the control end of the inverter element 266 is electrically connected to the positive terminal 18a of the connector 18. When the connector 18 outputs the input power Vin, the inverter element 266 is enabled, and when the voltage detection element 262 detects through the voltage divider circuit 264 that the voltage of the charging power Vc applied to the storage capacitor 30 is less than the predetermined voltage, the voltage detection element 262 outputs a low-level signal, which is converted into a high-level signal through the inverter element 266 to control the light-emitting element 28 to emit light; and when the voltage detection element 262 detects through the voltage divider circuit 264 that the voltage of the charging power Vc applied to the storage capacitor 30 reaches the predetermined voltage, the voltage detection element 262 outputs a high-level signal, which is converted into a low-level signal through the inverter element 266 to stop the light-emitting element 28 from emitting light. The voltage detection element 262 can be implemented by, for example, ME2807, XC62FN3812MR or an equivalent IC, and the inverting element 266 can be implemented by, for example, DTA144VUA or an equivalent IC.

In this embodiment, the rechargeable battery 1 further includes a power conversion module 32, which is electrically connected between the storage capacitor 30 and the positive electrode 12 and the negative electrode 14. The power conversion module 32 is used to convert the power of the storage capacitor 30 into the output power Vo. The power conversion module 32 includes a boost/buck element 34 to provide a stable output power Vo voltage. The boost/buck element 34 can be implemented, for example, by LTC3539-2, MP1601 or an equivalent IC. The boost/buck element 34 can be selectively electrically connected to a first adjustment resistor Ra1 and a second adjustment resistor Ra2.

The input end of the boost/buck element 34 can receive a voltage of 2.5V~4.2V, and outputs the corresponding output power Vo voltage in accordance with the ratio of the first adjustment resistor Ra1 and the second adjustment resistor Ra2. The output power Vo voltage is 1.2V×(1+Ra1/Ra2). In this embodiment, Ra1=137KΩ, Ra2=549KΩ, and the output power Vo voltage is 1.5V, i.e. 1.2×(1+137K/549K), but not limited to this. When Ra1=825KΩ, the output power Vo voltage is 3V, i.e. 1.2×(1+825K/549K). The output power Vo voltage can also be adjusted to 1.2V to 5.25V.

The output end of the boost/buck element 34 is electrically connected to the positive electrode 12, and the ground end of the boost/buck element 34 is electrically connected to the negative electrode 14 and the negative terminal 18b. In other words, the positive electrode 12 and the negative electrode 14 are electrically connected to the storage capacitor 30 via the power conversion module 32, and the output power Vo is output by the positive electrode 12 and the negative electrode 14. A filter capacitor Cf can be optionally connected between the positive electrode 12 and the negative electrode 14.

The charging management module 20 and the power conversion module 32 are disposed on a circuit board 36. Referring to FIG. 2 , the positive electrode 12 and the negative electrode 14 are spaced apart in an axial direction of the housing 10, and the circuit board 36 and the storage capacitor 30 are arranged between the positive electrode 12 and the negative electrode 14 in the axial direction. The storage capacitor 30 is located on one side of the circuit board 36 and between the circuit board 36 and the negative electrode 14. The storage capacitor 30 has two pins 302 (i.e., a positive terminal and a negative terminal), and the two pins 302 are connected to the circuit board 36 and electrically connected to the charging management module 20. At least one of the positive electrode 12 and the negative electrode 14 is connected to the circuit board 36 via at least one conductive member 38 to be electrically connected to the storage capacitor 30. In this embodiment, the negative electrode 14 is connected to the circuit board 36 via the conductive member 38 such as a metal spring, and can be electrically connected to the storage capacitor 30 through the power conversion module 32. The two pins 302, the conductive member 38, and the positive electrode 12 are soldered to the circuit board 36. In one embodiment, the negative electrode 14 can also be made of a metal sleeve and extend to the periphery of the circuit board 36. In this case, the conductive member 38 can use a pogo pin to connect the negative electrode 14 and the circuit board 36.

Through the above-mentioned structure, the power receiving module 16 receives external power and outputs the input power Vin. When the voltage of the input power Vin is greater than the voltage of the storage capacitor 30, the diode D1 is forward-conducted, and the storage capacitor 30 can be charged. Since the storage capacitor 30 has the advantage of fast charging, the charging time is less than 4 minutes. According to different types of storage capacitors 30, the charging time will also be less than 3.5 minutes, 1 minute, 15 seconds, or even less than 10 seconds. The smaller the capacitance value, the shorter the charging time. In this way, the storage capacitor 30 can be fully charged in a short time, which can greatly reduce the charging time compared to the commonly used rechargeable batteries.

FIG5 is a circuit block diagram of the rechargeable battery 2 of the second preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that the step-down circuit 42 of the charging management module 40 is composed of a diode D2, and the forward conduction voltage of the diode D2 is 1.1V.

The protection circuit 44 of this embodiment includes a current limiting resistor RL, one end of which is electrically connected to the cathode of the diode D2, and the other end of which is electrically connected to the positive end of the storage capacitor 30. Since the resistance value of the current limiting resistor RL is very small (for example, 1Ω), the voltage drop of the current limiting resistor RL is very small, so that the voltage of the cathode of the diode D2 can be regarded as the voltage of the charging power Vc. In practice, if the current limiting resistor RL is not used, the cathode of the diode D2 can be directly electrically connected to the positive electrode 12 of the storage capacitor 30, so that the power of the cathode of the diode D2 is the charging power Vc. The negative end of the storage capacitor 30 is electrically connected to the negative terminal 18b. In one embodiment, active current limiting components such as XC6209, XC6230 or equivalent ICs can also be used to implement this.

The charging indication circuit 46 of this embodiment includes a switch element such as a transistor Tr, a first resistor R1, and a second resistor R2. The transistor Tr has a first end, a second end, and a third end. The first end is electrically connected to the positive terminal 18a, the second end is electrically connected to the first resistor R1, and the third end is electrically connected to the second resistor R2. In this embodiment, the transistor Tr is a BJT. The transistor Tr is a PNP type BJT, but it is not limited to this. It can also be a FET. The first resistor R1 is electrically connected to one end of the light-emitting element 28, and the other end of the light-emitting element 28 is electrically connected to the negative terminal 18b. One end of the second resistor R2 is electrically connected to the positive end of the storage capacitor 30.

Through the above structure, the power receiving module 16 receives external power and outputs the input power Vin. When the voltage of the input power Vin is greater than the voltage of the storage capacitor 30, the diode D2 is forward-conducted to charge the storage capacitor 30, and the voltage at the third end of the transistor Tr causes the first end and the second end to conduct, so that the light-emitting element 28 emits light.

When the power receiving module 16 does not receive external power, or the voltage of the input power Vin is less than the voltage of the storage capacitor 30, the first end and the second end of the transistor Tr are cut off, and the light-emitting element 28 does not emit light.

FIG6 shows a circuit block diagram of the rechargeable battery 3 of the third preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that the power conversion module 48 includes a step-down element 50, which steps down the voltage of the power of the storage capacitor 30 to form the output power Vo. The step-down element 50 can be implemented, for example, by using an IC of model XC9265 or an equivalent.

FIG. 7 is a circuit block diagram of the rechargeable battery 4 of the fourth preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that the step-down circuit 51 of the present embodiment includes a step-down element 512 and a diode D1, and the step-down element 512 can be implemented by, for example, an IC of model RY3420 or equivalent. In addition, the power conversion module 32 is not provided in the present embodiment, and the positive end of the storage capacitor 30 is directly electrically connected to the positive electrode 12, and the negative end of the storage capacitor 30 can be electrically connected to the ground terminal via the protection element 24 to be electrically connected to the negative electrode 14. Thus, the power of the storage capacitor 30 can be directly output from the positive electrode 12 and the negative electrode 14 to form the output power Vo. The voltage of the output power Vo is the voltage of the storage capacitor 30. In this embodiment, the voltage of the storage capacitor 30 is 2.5~3.8V.

FIG8 and FIG9 are the rechargeable battery 5 of the fifth preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that the power receiving module 52 of the present embodiment includes a receiving coil 54 and a receiving circuit 56, and the receiving circuit 56 can be electrically connected to the charging management module 20, for example, by a flexible cable. The receiving coil 54 is used to receive external charging energy, and the receiving circuit 56 is electrically connected to the receiving coil 54 and converts the charging energy received by the receiving coil 54 into the input power Vin. In this way, the rechargeable battery 5 can be placed on a wireless charging board 200 to receive the charging energy of the wireless charging board 200 to charge the storage capacitor 30.

Please refer to Figure 10. When the rechargeable battery 5 is installed in an electronic device such as a remote controller 100, the remote controller 100 can be directly placed on the wireless charging plate 200. In this way, the rechargeable battery 5 can be charged without removing the rechargeable battery 5 from the remote controller 100.

The structure of the power receiving module 52 of this embodiment can also be applied to the second to fourth embodiments.

Please refer to Figure 11. When the output power Vo of the rechargeable battery 5 has a higher voltage, for example, the output power Vo of a single rechargeable battery 5 reaches 2.5V or 3V, another dummy battery 300 can be installed on the remote controller 100. The positive and negative electrodes of the dummy battery 300 are directly connected and connected in series with the rechargeable battery 5, so that the power of the rechargeable battery 5 is supplied to the remote controller 100. The remote controller 100 can be directly placed on the wireless charging plate 200, so that the rechargeable battery 5 can be charged without removing the rechargeable battery 5 from the remote controller 100.

Please refer to Figure 12, which is a rechargeable battery 6 of the sixth preferred embodiment of the present invention. It has a structure that is substantially the same as that of the first embodiment, except that the power receiving module 58 includes a receiving antenna 60, which is disposed on the housing 10. The receiving antenna 60 receives a wireless signal and converts the energy of the wireless signal into the input power Vin. The wireless signal is, for example, a wireless signal of Wi-Fi, Bluetooth, or a mobile network. In this way, the rechargeable battery 6 can be charged without a charging plate.

Please refer to FIG. 13 for a rechargeable battery 7 of the seventh preferred embodiment of the present invention, which has a structure substantially the same as that of the first embodiment, except that the power receiving module 62 includes a solar panel 64, which can be disposed outside the remote controller 100 and electrically connected to the charging management module 20 via a cable 66 connecting the connector 18. The solar panel 64 receives external light energy to charge the storage capacitor 30. In one embodiment, the solar panel 64 can also be replaced with a receiving coil 54 and a receiving circuit 56 as in the fifth embodiment, and electrically connected to the charging management module 20 via a cable 66 connecting the connector 18. The receiving coil 54 and the receiving circuit 56 can be integrated into a receiving chip, which is disposed on the outside or inside of the remote control 100 to receive the charging energy from the wireless charging plate 200.

Please refer to Figure 14, which is a rechargeable battery 8 of the eighth preferred embodiment of the present invention. It has a structure substantially the same as that of the first embodiment, except that the power receiving module 68 includes a solar panel 70, which is disposed on the housing 10 and electrically connected to the charging management module 20. The outer side of the solar panel 70 does not substantially protrude from the outer peripheral surface of the housing 70. Preferably, the outer side of the solar panel 70 is flush with the outer peripheral surface of the housing 70. Thus, the rechargeable battery 8 can be charged by placing it in a place with light.

Please refer to Figures 15 to 17 for a rechargeable battery 9 of a ninth preferred embodiment of the present invention, which has a structure substantially the same as that of the fifth embodiment, except that the outer peripheral surface 722 of the outer shell 72 is recessed to form a groove 724, and the connector 18 is located in the groove 724. The power receiving module 74 includes a cover plate 76 and a male connector 78, the receiving coil 54 and the receiving circuit 56 are disposed in the cover plate 76, and the cover plate 76 is in an arc shape that matches the groove 724. The male connector 78 is disposed on the inner side surface 762 of the cover plate 76 and is electrically connected to the receiving circuit 56. The outer side surface 764 of the cover plate 76 does not substantially protrude from the outer peripheral surface 722 of the outer shell 72. Preferably, the outer side surface 764 of the cover plate 76 is flush with the outer peripheral surface 722 of the outer shell 72. The cover plate 76 is detachably disposed on the outer shell 72 and is located in the groove 724. The male connector 78 is detachably connected to the connector 18. In this way, the rechargeable battery 9 can be placed on the wireless charging plate 200 for charging. When the wireless charging function is not used, the cover plate 76 can be removed, and another male connector with power can be inserted into the connector 18.

Please refer to Figures 18 and 19 for the rechargeable battery A of the tenth preferred embodiment of the present invention, which is based on the structure of the first embodiment and further includes a wireless signal transceiver 80, which is disposed inside the housing 10. The wireless signal transceiver 80 is electrically connected to the positive electrode 12 and the negative electrode 14 to receive the output power Vo for operation. In this embodiment, the wireless signal transceiver 80 is electrically connected to the positive electrode 12 through a diode D. The rechargeable battery A is installed in an electronic device (such as a remote control 100).

The wireless signal transceiver 80 may be, for example, a smart tag. The wireless signal transceiver 80 is used to send a wireless signal carrying an identification code, and the wireless signal transceiver 80 may communicate with a mobile device 400, and the mobile device 400 records the identification code and the electronic device or rechargeable battery corresponding to the identification code. The wireless signal may be, for example, a Bluetooth signal. Thus, when the wireless signal transceiver 80 continues to send the wireless signal, the mobile device 400 may receive the wireless signal, and may determine the electronic device or rechargeable battery corresponding to the received wireless signal transceiver 80 by the identification code, and may determine the position of the wireless signal transceiver 80 relative to the mobile device 400 by the wireless signal.
