DETAILED DESCRIPTION
[0025] The present application will be further described in detail below in conjunction with the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustrating the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only part of the embodiments of the present application, but not all the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without making creative efforts are within the scope of protection of the present application.
[0026] The terms "first", "second", "third" in the embodiments of the present application are only used for descriptive purpose and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise explicitly and specifically limited. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly. The terms "include" and "have" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or components inherent to the process, method, product or device.
[0027] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive or alternative embodiments. It is expressly understood that the embodiments described herein can be combined with each other in their various permutations and combinations.
[0028] The output power of the atomization device has many kinds, low gear has several watts, tens of watts, middle gear has twenty or thirty watts, high gear has more than fifty watts. Under the premise of constant heating wire resistance, the higher the output power, the stronger the taste explosion. According to the Ampere law, that is, the formula: current I = voltage U / resistance R. Conversion to get the formula: voltage drop U1 = current I * resistance R. It can be concluded that in the case of constant circuit impedance R (i.e. resistance in the equation), the greater the output current I, the greater the voltage drop U1. The voltage drop in the circuit refers to the decrease or consumption of voltage when the current passes through the circuit components. The voltage drop in the circuit is usually caused by elements such as resistance, inductance and capacitance. The atomization device often needs to output large current (for example, more than 5A) to meet the requirement of load power in the middle and high gear of output power. In the case of such large current output, if the battery has poor discharge performance and the circuit resistance is high, it will cause the voltage drop U1 to be too large, thereby seriously affecting the taste. The full charge voltage of the battery of the existing atomization device is less than 4.2V, if the battery voltage drop is 0.35V when the required discharge current is 7A, then the discharge voltage of the battery in the load state is 4.2V-0.35V = 3.85V, which is difficult to meet the power supply requirement of large current.
[0029] The embodiment of the present application provides a power supply assembly 10, such as Figure 1 As shown, the power supply assembly 10 comprises a battery core 110 and a charging module 120, the battery core 110 is configured to reach a required voltage at full voltage and reach a required current at discharge current; the charging module 120 is electrically connected with the battery core 110, the charging module 120 is used for coupling an external charging device, the charging module 120 comprises a charging management chip 121, the charging management chip 121 is used for supporting the battery core 110 to reach the required voltage at full voltage; wherein the required voltage is greater than 4.2V, and the required current is greater than 5A.
[0030] In the above embodiment, the required voltage refers to an expected voltage value set artificially; the full voltage refers to the discharge voltage of the battery core 110 in a full or near-full state, for example, the battery core 110 is in a full state when the power is 90%-100%; the required current refers to an expected current value set artificially, and the discharge current refers to the discharge current of the battery core 110 in a full or near-full state.
[0031] The method for improving the full voltage of the battery core 110 comprises modifying the material structure of the battery core 110 to meet the high voltage value in the full state, and simultaneously modifying the charging circuit to support charging the battery core 110 with high full voltage.
[0032] The present application supports that the voltage of the battery core 110 can be greater than 4.2V when fully charged by setting the charging management chip 121, so that the discharge voltage of the battery core 110 can have a higher value when the discharge current is greater than 5A, that is, the discharge voltage of the battery core 110 can have a higher value when the discharge current is greater than 5A, even if it is affected by voltage drop, to meet the power supply requirement of the load.
[0033] In some embodiments, the required voltage can be 4.25-4.45V. Specifically, the required voltage can be 4.25V, 4.35V, 4.4V, 4.45V and any value between the above voltage values.
[0034] In some embodiments, the full voltage of the battery core 110 is 4.35V, and after subtracting the voltage drop caused by the battery core 110 itself, a higher discharge voltage can still be maintained. For example, if the voltage drop of the battery core 110 itself is 0.35V when the discharge current is required to be 7A, the discharge voltage of the battery core 110 in the load state is 4.2V-0.35V=4.0V. The battery core 110 with full voltage 4.35V can provide 4.0V voltage output for the load when discharging at 7A. When supporting large-current load discharge output, the full voltage value of the battery core 110 can be directly and effectively improved to meet and improve the power supply requirement of the load.
[0035] In some embodiments, as shown in Figure 2As shown, the charging module 120 further includes a discharging circuit 122 coupled to the input pin IN of the charging management chip 121, and the discharging circuit 122 is configured to absorb a surge signal. The surge is a peak value that appears instantaneously beyond a stable value, which includes a surge voltage and a surge current. Essentially, the surge is a sharp pulse that occurs within only a few millionths of a second. The surge can be caused by a short circuit, power switching, electromagnetic interference, etc.
[0036] In some embodiments, the input end VIN of the charging module 120 is coupled to the input pin IN of the charging management chip 121, and the input end VIN can be inserted into an external charging device through an interface such as a USB. The discharging circuit 122 mainly absorbs the spike and surge signals caused by the external charging device to protect the power supply assembly 10 when the battery cell 110 is charging. The required voltage of the present application is greater than 4.2V, and thus the voltage provided by the input end VIN is greater than the required voltage, for example, the voltage of the input end VIN can be 5V or more. A large increase in voltage within a short period of time can cause spikes and surges to occur. When the external charging device is connected to the input end VIN, the voltage of the input end VIN can increase sharply within a short period of time, which can cause spikes and surges. The discharging circuit 122 can absorb the spike and surge signals when the input end VIN is connected to a large voltage, thereby ensuring charging safety.
[0037] In some embodiments, the discharging circuit 122 includes a first resistor R1 and a first capacitor C1. The first end of the first resistor R1 is coupled to the input end VIN and the input pin IN, and the second end of the first resistor R1 is coupled to the first end of the first capacitor C1. The second end of the first capacitor C1 is grounded. The first resistor R1 and the first capacitor C1 can form an RC circuit. The RC circuit, which stands for resistor-capacitor circuit, can utilize the charging and discharging characteristics of the capacitor to achieve functions such as signal delay, shaping, filtering, etc., for absorbing and attenuating overvoltage and overcurrent phenomena in the circuit caused by the rapid switching of switching elements.
[0038] In some embodiments, the resistance value of the first resistor R1 can be 4.7Ω, and the capacitance value of the first capacitor C1 can be 10μF.
[0039] In some embodiments, the charging module 120 further comprises a voltage division detection circuit 123 coupled to the input pin IN of the charging management chip 121, which is used to detect the charging state. The voltage division detection circuit 123 can reduce the high voltage to a range suitable for detection by the resistance voltage division principle, so as to monitor and control the voltage state in real time, and ensure the safe and stable operation of the circuit. For example, when the input end VIN of the charging module 120 is connected to an external charging device for 5V charging, the input end VIN will generate a high level of 5V, at which time the voltage division detection circuit 123 can reduce the voltage to a range suitable for detection and send it to the central processing unit to achieve plug detection.
[0040] In some embodiments, the voltage division detection circuit 123 comprises a second resistor R2 and a third resistor R3, the first end of the second resistor R2 is coupled to the input pin IN, the second end of the second resistor R2 is coupled to the first end of the third resistor R3 and the voltage detection end VCC_DET, and the second end of the third resistor R3 is grounded. The second resistor R2 and the third resistor R3 can divide the voltage of the input end VIN, so that the voltage at the voltage detection end VCC_DET is within a range suitable for detection, and the central processing unit can determine whether the external charging device is connected for charging according to the voltage at the voltage detection end VCC_DET.
[0041] In some embodiments, the resistance value of the second resistor R2 can be 100KΩ, and the resistance value of the third resistor R3 can be 200KΩ.
[0042] In some embodiments, the model of the charging management chip 121 can be LP4073H, ME4056, or FS4057D, etc.
[0043] In some embodiments, the charging module 120 further comprises a fourth resistor R4 and a fifth resistor R5. The first end of the fourth resistor R4 is coupled to the enable pin EN of the charging management chip 121, and the second end of the fourth resistor R4 is grounded. The first end of the fifth resistor R5 is coupled to the current limit pin ISET of the charging management chip 121, and the second end of the fifth resistor R5 is grounded.
[0044] Specifically, the enable pin EN is used to control the switching state of the charging management chip 121, so that the charging management chip 121 is in working or standby mode. The current limit pin ISET can be used to limit the output current to avoid overload or short circuit.
[0045] In some embodiments, the resistance value of the fourth resistor R4 can be 100KΩ, and the resistance value of the fifth resistor R5 can be 1.7KΩ.
[0046] In some embodiments, the charging module 120 further includes a second capacitor C2. The first terminal of the second capacitor C2 is coupled to the battery monitoring pin BAT of the charging management chip 121 and the output terminal VBAT of the charging module 120, and the second terminal of the second capacitor C2 is grounded. The capacitance value of the second capacitor C2 can be 10μF.
[0047] Specifically, the output terminal VBAT is used to connect to the battery cell 110 and charge the battery cell 110. The battery monitoring pin BAT can detect whether the battery cell 110 has sufficient power, so as to realize functions such as charging the battery cell 110 and battery protection.
[0048] In some embodiments, such as Figure 3 As shown, the charging module 120 also includes a temperature sensor 124, a voltage detection circuit 125, and a current detection circuit 126. The temperature sensor 124 is used to detect the temperature of the battery cell 110 and output temperature detection information; the voltage detection circuit 125 is used to detect the charging voltage of the battery cell 110 and output voltage detection information; the current detection circuit 126 is used to detect the charging current of the battery cell 110 and output current detection information; the charging management chip 121 is configured to receive and analyze the temperature detection information, voltage detection information, and current detection information, and then regulate the charging voltage and charging current.
[0049] In some embodiments, the charging management chip 121 can employ a charging mode combining constant current charging and constant voltage charging. The charging management chip 121 can detect the voltage of the battery cell 110 itself. When the voltage of the battery cell 110 is lower than the full-charge voltage, it enters the constant current charging mode; when the voltage of the battery cell 110 is close to the full-charge voltage, it enters the constant voltage charging mode, and the charging current gradually decreases. To ensure that the full-charge voltage of the battery cell 110 reaches the required voltage, the charging voltage of the battery cell 110 during constant voltage charging must be greater than or equal to the required voltage. High-voltage charging can accelerate the chemical reaction inside the battery cell 110, causing the internal temperature of the battery cell 110 to rise, potentially leading to overheating or even the risk of fire or explosion. Therefore, the charging module 120 uses a temperature sensor 124, a voltage detection circuit 125, and a current detection circuit 126 to monitor the temperature of the battery cell 110 in real time. When the temperature of the battery cell 110 rises, the charging management chip 121 can reduce the charging voltage or charging current to reduce the heat generated during the charging process, ensuring the safety of the charging process while maintaining the charging voltage at or above the required voltage.
[0050] In some embodiments, the charging management chip 121 monitors parameters such as the charging voltage, charging current, temperature, and the voltage of the battery cell 110 to control the magnitude of the charging current and the charging cutoff voltage, ensuring the safety and stability of the charging process. The charging cutoff voltage can be the required voltage. When the temperature of the battery cell 110 is too high or the voltage of the battery cell 110 reaches the charging cutoff voltage, the charging management chip 121 can take measures, such as reducing the charging current or stopping charging, to protect the battery cell 110 from overheating damage.
[0051] In some embodiments, the charging management chip 121 may have a built-in temperature sensor 124, voltage detection circuit 125, and current detection circuit 126. In other embodiments, the charging management chip 121 may have an external temperature sensor 124, voltage detection circuit 125, and current detection circuit 126.
[0052] In some embodiments, such as Figure 4 As shown, the charging management chip 121 in the charging module 120 may include a first charging management chip 1211 and a second charging management chip 1212. The first charging management chip 1211 and the second charging management chip 1212 may be connected in parallel to support the full-charge voltage of the battery cell 110 to reach the required voltage. By setting two charging management chips 121 to distribute heat and current, the operating temperature of a single charging management chip 121 is reduced, thereby improving the reliability of the system.
[0053] In some embodiments, such as Figure 5 As shown, the power supply assembly 10 also includes a control circuit 130, which is coupled to the battery cell 110. The control circuit 130 includes a control component 131 electrically connected to the atomizer 20, and the resistance of the control component 131 is 4 to 6 mΩ. The control circuit 130 can be used to control the battery cell 110 to supply power to the atomizer 20.
[0054] In some embodiments, the resistance of the control component 131 can be 5mΩ, the control component 131 can be a P-MOS transistor, and the model of the control component 131 can be AP20P01BF or other P-MOS transistors with a resistance of 4 to 6mΩ.
[0055] According to the formula (voltage drop U1 = current I * resistance R), reducing the resistance value of the circuit in the control circuit 130, including reducing the internal resistance value of the device in the circuit, can directly and effectively reduce the voltage drop U1 value. The resistance value of the P-MOS tube component connected with the atomizer 20 in the existing atomization device is 15 mΩ, and the control component 131 in the present application is reduced from 15 mΩ to 5 mΩ. If the circuit requires an output of 10 A, the voltage drop value can be effectively reduced through calculation: voltage drop U1 = (15 mΩ-5 mΩ) * 0.001 Ω * 10 A = 0.1 V, that is, the control component 131 can reduce the voltage drop by 0.1 V by reducing the internal resistance value from 15 mΩ to 5 mΩ.
[0056] In some embodiments, the control circuit 130 can also be coupled with the voltage detection end VCC_DET to detect the charging condition of the battery cell 110, and can control the power supply state of the battery cell 110 to the atomizer 20 according to the charging condition of the battery cell 110.
[0057] In some embodiments, the power supply assembly 10 includes a conductive terminal 140 for electrically connecting with the atomizer 20, and the plating material of the conductive terminal 140 is copper-gold plating. The power supply assembly 10 and the atomizer 20 can be detachably connected, and the output connection is achieved through terminal contact. A larger resistance value of the conductive terminal 140 will also result in a larger voltage drop. In the present application, the plating material of the conductive terminal 140 is changed from iron-gold plating to copper-gold plating to reduce the resistance value of the conductive terminal 140, so that the voltage drop is reduced.
[0058] In some embodiments, the thickness and purity of the gold plating of the conductive terminal 140 can be improved to reduce the resistance value of the conductive terminal 140; or the plating process can be improved to make the plating layer of the conductive terminal 140 more uniform and flat, so as to reduce the resistance value of the conductive terminal 140.
[0059] In some embodiments, the conductive terminal 140 can be a spring sheet, and the cross-sectional area of the spring sheet can be increased, for example, the thickness and width of the copper sheet can be increased, or the length of the spring sheet can be reduced, so as to reduce the resistance value of the conductive terminal 140.
[0060] The present application also provides an atomization device, which includes the power supply assembly 10 of the above-mentioned embodiments, and further includes an atomizer 20, and the power supply assembly 10 is electrically connected with the atomizer 20 to supply power to the atomizer 20.
[0061] The atomization device and the power supply assembly 10 provided by the application can make the full voltage of the battery cell 110 reach the required voltage by arranging the charging management chip 121, so as to improve the voltage drop problem when the discharge current is a large current, and further reduce the voltage drop by reducing the resistance value of the control circuit 130 and the conductive terminal 140. The application reduces the voltage drop of the whole machine by combining the two ways of improving the full voltage value of the battery cell 110 and reducing the impedance resistance value in the circuit, and improves the atomization effect and user experience.
[0062] The above only describes some embodiments of the application, and does not limit the protection scope of the application, and any equivalent device or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
