Description

Technical Field

[0001] This utility model relates to the field of smart home appliances, and in particular to a fast discharge device. Background Technology

[0002] Currently, the main methods for rapid battery discharge in the industry are as follows:

[0003] 1. Resistance Discharge Method: This method converts the battery's electrical energy into heat energy by connecting a resistor, thus achieving rapid discharge. Choose a suitable resistor whose resistance value matches the battery's voltage and capacity; connect the two ends of the resistor in series with the battery's positive and negative terminals; wait for the battery to discharge.

[0004] 2. Variable resistor discharge method: A variable resistor is connected to a rechargeable battery. By adjusting the variable resistor, different discharge currents can be obtained.

[0005] 3. Using a discharger: A discharger is a device specifically designed for discharging batteries. It can quickly discharge lithium batteries by setting the discharge current and time. Dischargers have multiple output ports and can discharge multiple batteries simultaneously.

[0006] 4. Load resistor discharge: A load resistor is a resistor whose resistance value can be adjusted to control the current. Connecting a load resistor to the positive and negative terminals of a lithium battery can quickly discharge the battery.

[0007] 5. Increase discharge current: Increasing the discharge current can accelerate the rate of electrochemical reactions, thereby achieving rapid discharge. However, it should be noted that excessive current may cause the battery to overheat and be damaged.

[0008] 6. Use high discharge rate batteries: Some batteries are designed for high discharge rate and can withstand greater current output, thus achieving rapid discharge.

[0009] 7. Control battery temperature: Appropriately increasing the battery temperature can accelerate the electrochemical reaction, but excessively high temperatures will damage the battery's performance and lifespan.

[0010] 8. Use pulse discharge: Pulse discharge mode can effectively improve the battery's discharge efficiency, reduce the influence of internal resistance, and achieve rapid discharge.

Utilizing the device's built-in discharge function can avoid these problems.

[0038] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0040] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0041] Current rapid discharge methods can negatively impact battery lifespan. Frequent rapid discharges accelerate the aging process and shorten the battery's lifespan. This problem can be avoided if the device itself can discharge the battery.

[0042] To address the above problems, this invention proposes a rapid discharge method, which includes the following steps:

[0043] Detect the initial operating parameters of the target battery;

[0044] Discharge the target battery when the initial operating parameters meet the discharge conditions;

[0045] Real-time monitoring of the target battery's current operating parameters during the discharge process, and setting the target battery's discharge action based on the current operating parameters;

[0046] If the current operating parameters do not meet the discharge conditions, stop discharging the target battery.

[0047] As can be seen from the above discharge process, the discharge action of this invention is adjusted according to the current operating parameters during the discharge process. This not only ensures efficient discharge but also avoids damage to the target battery to a certain extent.

[0048] The target battery in this utility model is a battery for a mobile terminal device;

[0049] The mobile terminal device can be a mobile phone, laptop, iPad, etc. As mentioned above, the discharge action in this utility model is based on the function of the device itself. That is, the discharge action in this utility model is based on the function of the mobile terminal device itself, such as turning on the camera, flash, adjusting the screen brightness, etc. This discharge method has the least impact on the damage to the target battery.

[0050] Specifically, the discharge action in this utility model includes:

[0051] First discharge action: Turn on the camera and flash of the mobile terminal device;

[0052] Second discharge action: Adjusting the brightness of the mobile terminal device's display screen;

[0053] The third discharge action: Adjusting the CPU operating load of the mobile terminal device;

[0054] Fourth discharge action: Activate the music playback function of the mobile terminal device;

[0055] Fifth discharge action: Activate the wireless communication module of the mobile terminal device;

[0056] The sixth discharge action: reverse output through the charging interface of the mobile terminal device.

[0057] It should be noted that the above six discharge actions are only discharge actions under a preferred embodiment of this utility model. In other embodiments of this utility model, only some discharge actions may be selected, which can also achieve the same discharge effect.

[0058] The above-mentioned discharge actions are all based on the current operating parameters of the target battery during the discharge process. Specifically, the current operating parameters in this utility model include: the current charge of the target battery and the current temperature of the target battery.

[0059] Here, the current charge level of the target battery is used to control whether the discharge action is executed. If the current charge level of the target battery is lower than the target charge level, that is, the standard for completing the discharge has been reached, then all discharge actions can be stopped to stop discharging the target battery.

[0060] The current temperature of the target battery is used to allocate the discharge action. In this invention, the current temperature range of the target battery is divided into four temperature ranges, and each temperature range corresponds to a different discharge action, thereby ensuring the best discharge effect on the target battery.

[0061] Based on the above-mentioned current operating parameters, the initial operating parameters in this utility model are also set to the initial charge and initial temperature of the target battery.

[0062] The discharge conditions are set as follows: the initial or current charge of the target battery is higher than the target charge, and the initial or current temperature of the target battery is lower than the target temperature.

[0063] Based on the above settings, in this utility model, the discharge action will only be performed when the initial charge of the target battery is higher than the target charge and the initial temperature of the target battery is lower than the target temperature. In this utility model, the target charge is preferably 19%, and the target temperature is preferably the highest temperature that will not damage the battery, which is set to 55°C.

[0064] That is, this utility model will only discharge the target battery when the initial charge of the target battery is higher than 19% and the initial temperature is lower than 55°C. During the discharge process, the current operating parameters of the target battery will be monitored in real time. If the above discharge conditions are not met, the discharge action on the target battery will be stopped.

[0065] Please see Figure 1 The flowchart for discharging the target battery in this utility model first executes the "setting target charge and target temperature" function, where the target charge is set to 19% and the target temperature is set to 55%.

[0066] Then, the judgments of "current battery level is lower than target battery level" and "current temperature is higher than target temperature" are executed respectively. The target battery will only be discharged when both judgments are negative, that is, when the initial operating parameters meet the discharge conditions.

[0067] During the discharge process, it is necessary to "record the current battery charge and temperature", which means to monitor the current operating parameters in real time.

[0068] Discharge will stop when either "current charge level reaches target charge level" or "current temperature reaches target temperature" is met. Figure 1 The option to "turn off all functions" will be selected, while the option to "turn off all functions" will be selected, which will take you to the settings for the discharge action.

[0069] Appendix Figure 1 The document only describes the execution process of the flash and camera (i.e., the first discharge action) when the temperature is 50°C. In a preferred embodiment of this utility model, the temperature range of the target battery is divided into four, and different discharge actions are configured according to the four different temperature ranges.

[0070] Specifically, the discharge action of the target battery, as described above, is set based on the current operating parameters, including:

[0071] Determine the current temperature range of the target battery. When the target battery's temperature range is within the first temperature range, initiate the second, third, fourth, and fifth discharge actions.

[0072] When the target battery's temperature range is within the second temperature range, initiate the full discharge action;

[0073] When the target battery's temperature range is in the third temperature range, the second, third, fourth, and fifth discharge actions are activated.

[0074] When the target battery's temperature range is in the fourth temperature range, shut down all discharge operations.

[0075] As can be seen, this utility model is equipped with corresponding discharge actions in four temperature ranges to ensure optimal discharge efficiency.

[0076] The first temperature range is 0 to 15℃, the second temperature range is 16℃ to 49℃, the third temperature range is 50℃ to 55℃, and the fourth temperature range is 56℃ to 60℃.

[0077] As can be seen from the above temperature range settings, the temperature in the fourth temperature range is higher than the target temperature. Therefore, in the fourth temperature range, the discharge action performed by this invention is to shut down all discharge actions, that is, to stop the discharge.

[0078] Furthermore, during the discharge process of the target battery, abnormal discharge parameters may occur due to malfunctions in some components. Continuing to discharge may damage the target battery. To avoid the above problems, the rapid discharge method proposed in this invention includes:

[0079] Real-time monitoring of discharge parameters of the target battery during the discharge process;

[0080] When the discharge parameters exceed the threshold parameters, stop discharging the target battery.

[0081] The discharge parameters here include: discharge current, discharge voltage, and operating temperature. When any of these discharge parameters exceeds the threshold parameter, it indicates that the target battery has a discharge abnormality and discharge needs to be stopped.

[0082] Among them, the above discharge parameters must meet the general standards of the battery industry, namely, the maximum discharge current is 3.6A, the discharge cutoff voltage is 3V, and the target battery operating temperature is between -20 and 60℃.

[0083] If any of the above operating parameters does not meet the above conditions, the discharge needs to be stopped to avoid damage to the target battery.

[0084] Based on the above settings, the discharge mechanisms that can be identified for the target battery in this utility model are:

[0085] 1. At room temperature (23±2℃), it can achieve a maximum rapid discharge of 0.7C;

[0086] 2. Rapid discharge at 0.2C can be achieved at low temperatures of 0–15℃;

[0087] 3. Rapid discharge at 0.2C can be achieved at high temperatures of 50℃~60℃;

[0088] 4. The discharge current will automatically switch when the temperature reaches the above range.

[0089] Furthermore, based on the above-mentioned rapid discharge method, this utility model also proposes a rapid discharge device, which is mainly used for detecting the above-mentioned discharge parameters and avoiding damage to the target battery caused by the discharge parameters exceeding the threshold parameters.

[0090] Specifically, the fast discharge device proposed in this utility model includes: a main control module, a charging interface connected to the main control module, a music module, a communication module, a screen, a camera or flash, and a logic judgment module. The logic judgment module is also connected to a current detection module, a voltage detection module, and a temperature detection module.

[0091] The current detection module, voltage detection module, and temperature detection module are used to detect the discharge parameters of the target battery, and the logic judgment module is used to determine whether the discharge parameters exceed the threshold parameters.

[0092] The charging port, music module, communication module, screen, and camera or flash are used to perform the discharge action.

[0093] Please see Figure 2 The aforementioned main control unit, also known as the MCU, is connected to a camera and a flash, which are mainly used to perform the aforementioned first discharge action.

[0094] The screen connected to the main control unit is also the display screen of the mobile terminal device, which is mainly used to perform the second discharge action;

[0095] The main control unit is connected to a wireless communication module, which is mainly used to execute the fifth discharge action;

[0096] The music module connected to the main control unit is used to execute the fourth discharge action;

[0097] The charging interface connected to the main control unit is used to perform the sixth discharge action;

[0098] For the third discharge action, the CPU is generally a functional component of the motherboard itself, therefore it is not included in the attached... Figure 2 The description is provided in the text, and it can be achieved through the control of the main control unit itself;

[0099] The aforementioned current detection module is used to detect the discharge current of the target battery, the voltage detection module is used to detect the discharge voltage of the target battery, the temperature detection module is used to detect the operating temperature of the target battery during the discharge process, and the logic judgment module is mainly used to perform logic judgments to ensure that if any of the above discharge parameters exceeds the threshold parameter, a corresponding signal can be sent to the main control unit to stop the discharge action.

[0100] Based on the above design, this utility model can realize real-time detection of discharge parameters and stop discharging when the discharge parameters exceed the threshold parameters, so as to protect the target battery.

[0101] Furthermore, the aforementioned current detection module, voltage detection module, and temperature detection module each have at least one comparison unit, which is used to determine whether the discharge current exceeds the maximum discharge current, whether the discharge voltage exceeds the discharge cutoff voltage, and whether the operating temperature exceeds the target temperature, respectively. The input terminals of all comparison units used to obtain the reference voltage are connected to the same series circuit.

[0102] The logic judgment module has at least one logic OR gate, and can output a discharge stop signal to the main control module when any discharge parameter exceeds the threshold parameter.

[0103] The comparison unit here can be set as a comparator, which is used to compare with the reference voltage to determine whether the discharge current exceeds the maximum discharge current, whether the discharge voltage exceeds the discharge cutoff voltage, and whether the operating temperature exceeds the target temperature.

[0104] In this invention, all the input terminals of the comparator units used to obtain the reference voltage are connected to the same series circuit, which can save the use of components to the greatest extent. At the same time, since different comparators require different reference voltages, after adopting the above-mentioned series connection method, due to the voltage division effect of the series connection, the voltage between any two resistors can be different. Then, by connecting the input terminals of the comparator used to obtain the reference voltage to different positions, different reference voltages can be obtained.

[0105] Compared to traditional solutions, this invention only requires a single series circuit to provide multiple reference voltages, eliminating the need for multiple reference voltage circuits and reducing circuit design costs.

[0106] Please see Figure 3 The current detection module in this utility model includes: resistor R1, resistor R2, resistor R10, and comparator U1A;

[0107] The voltage detection module includes: resistors R3, R4, and R11, and comparator U1B;

[0108] The temperature detection module includes: resistor R5, resistor R12, thermistor RT1, and comparator U1C;

[0109] The series circuit includes: resistor R6, resistor R7, resistor R8, and resistor R9;

[0110] One end of resistor R1 is connected to the discharge current, and the other end of resistor R1 is connected in series with resistor R2 and then grounded. One end of resistor R3 is connected to the discharge voltage, and the other end of resistor R3 is connected in series with resistor R4 and then grounded. One end of resistor R5 is connected to a 5V power supply, and the other end of resistor R5 is connected in series with thermistor RT1 and then grounded. One end of resistor R6 is connected to a 5V power supply, and the other end of resistor R6 is connected in series with resistors R7, R8, and R9 and then grounded.

[0111] The non-inverting input of comparator U1A is connected between resistors R1 and R2, the inverting input of comparator U1A is connected between resistors R6 and R7, and the output of comparator U1A is connected in series with resistor R10 as the output of the current detection module.

[0112] The non-inverting input of comparator U1B is connected between resistors R3 and R4, and the inverting input of comparator U1B is connected between resistors R7 and R8. The output of comparator U1B is connected in series with resistor R11 and serves as the output of the voltage detection module.

[0113] The non-inverting input of comparator U1C is connected between resistor R5 and the thermistor RT1, and the inverting input of comparator U1C is connected between resistor R8 and resistor R9. The output of comparator U1C is connected in series with resistor R12 and serves as the output of the temperature detection module.

[0114] Furthermore, the logic judgment module includes: resistor R13, resistor R14, switch Q1, OR gate OR1, OR gate OR2, and OR gate OR3;

[0115] The first input terminal of OR gate OR1 is connected to the output terminal of the current detection module, the second input terminal of OR gate OR1 is connected to the output terminal of the voltage detection module, and the output terminal of OR gate OR1 is connected to the first input terminal of OR gate OR3.

[0116] The first input terminal of OR2 is connected to the output terminal of the voltage detection module, and the second input terminal of OR2 is connected to the output terminal of the temperature detection module. The output terminal of OR2 is connected to the second input terminal of OR3.

[0117] The output of OR3 is connected in series with resistor R13 and then connected to the third terminal of switch Q1. The first terminal of switch Q1 is connected to a 5V power supply, and the second terminal of switch Q1 is connected to the main control module. One end of resistor R14 is connected between resistor R13 and the third terminal of switch Q1, and the other end of resistor R14 is connected between the second terminal of switch Q1 and the main control module.

[0118] Please see Figure 3 The working principles of the aforementioned current detection module, voltage detection module, temperature detection module, and logic judgment module are as follows:

[0119] Resistors R6, R7, R8, and R9 are connected in series to divide the voltage. The voltage across each resistor is proportional to its resistance value. The inverting input of comparator U1A is connected between resistors R6 and R7 to obtain a reference voltage, the magnitude of which is 5*(R7+R8+R9) / (R6+R7+R8+R9). The inverting input of comparator U1B is connected between resistors R7 and R8 to obtain a reference voltage, the magnitude of which is 5*(R8+R9) / (R6+R7+R8+R9). The inverting input of comparator U1C is connected between resistors R8 and R9 to obtain a reference voltage, the magnitude of which is 5*(R8+R9) / (R6+R7+R8+R9).

[0120] The discharge current is connected to one end of resistor R1 and converted into voltage through the resistor. According to Ohm's law, the voltage across resistor R2 is Io*R2. The non-inverting input of comparator U1A is connected between resistors R1 and R2 to obtain the voltage Io*R2. By setting the value of resistor R2, when the discharge current exceeds the maximum discharge current of 3.6A, the voltage at the non-inverting input of comparator U1A is higher than the voltage at the inverting input. At this time, comparator U1A outputs a high-level signal. In other words, the working principle of the current detection module is to set the values ​​of resistors R2, R6, R7, R8, and R9 so that when the discharge current exceeds the maximum discharge current of 3.6A, it outputs a high-level signal, and vice versa.

[0121] The voltage detection module and temperature detection module work similarly to the current detection module. For the voltage detection module, the voltage obtained at the non-inverting input terminal of comparator U1B is set according to the voltage division of resistors R3 and R4, and its value is Vo*R4 / (R3+R4). By setting the resistance values ​​of resistors R3, R4, R6, R7, R8, and R9, the voltage at the non-inverting input terminal of comparator U1B is higher than the voltage at the inverting input terminal when the discharge voltage exceeds the discharge cutoff voltage of 3V. At this time, the voltage detection module outputs a high-level signal, and vice versa.

[0122] For the temperature detection module, the voltage obtained at the non-inverting input of comparator U1C is set according to the voltage division of resistor R5 and thermistor RT1. Unlike the current detection module and the voltage detection module, the voltage provided at resistor R5 in the temperature detection module is a stable voltage. The voltage obtained at the non-inverting input of comparator U1C is 5*RT1 / (R5+RT1), and its magnitude changes according to the value of thermistor RT1. Since the resistance of thermistor changes with temperature, it is only necessary to select a suitable thermistor so that its voltage is higher than the voltage at the inverting input of comparator U1C when the temperature exceeds the target temperature. This satisfies the above logic of outputting a high-level signal when the operating temperature of the target battery exceeds the target temperature, and outputting a low-level signal otherwise.

[0123] For the logic judgment module, the two input terminals of OR gate OR1 are connected to the output terminals of the current detection module and the voltage detection module, respectively. Therefore, when either the current detection module or the voltage detection module outputs a high-level signal, OR gate OR1 will output a high-level signal. Similarly, OR gate OR2 outputs a high-level signal when either the voltage detection module or the temperature detection module outputs a high-level signal. OR gate OR3 outputs a high-level signal when either OR gate OR1 or OR gate OR2 outputs a high-level signal. That is, for OR gate OR3, as long as any one of the current detection module, voltage detection module, or temperature detection module outputs a high-level signal, it will output a high-level signal. Since OR gate OR3 is connected to the third terminal of the switching transistor Q1 through resistor R13, i.e., the control terminal, when OR gate OR3 outputs a high-level signal, the switching transistor Q1 is turned on. At this time, the 5V power supply is connected to the MCU, and the MCU can receive the high-level signal.

[0124] In summary, the working principle of the current detection module, voltage detection module, temperature detection module, and logic judgment module in this utility model is as follows: when any one of the discharge current, discharge voltage, or operating temperature exceeds its threshold parameter, the main control module outputs a high-level signal. That is, when any discharge parameter exceeds the threshold parameter, the main control module outputs a high-level signal. At this time, the main control module can control all discharge actions to stop and stop the discharge, thus avoiding the problem of abnormal discharge current, discharge voltage, and operating temperature of the target battery during the discharge process, and further avoiding damage to the target battery.

[0125] The above-mentioned discharge schemes in this utility model can all utilize the Service component and BroadcastReceiver component technology in the Android system of mobile terminal devices to manage battery voltage, current, capacity, temperature, etc., and call relevant device functions based on the Android system architecture and related API interfaces to enable rapid discharge.

[0126] The maximum discharge current of this invention can reach 3.6A. Under good ventilation conditions (temperature within 16-49℃), it can discharge completely within 1.39 hours for a voltage of 5000mA.

[0127] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0128] The discharge actions of this invention are all based on the functions of the mobile terminal device itself, such as the camera, flash, and display screen. Compared with current physical fast discharge solutions, this avoids adverse effects on battery life. Simultaneously, this invention monitors the target battery's current operating parameters in real time during the discharge process and sets corresponding discharge actions based on these parameters, ensuring the most reasonable and efficient discharge. Furthermore, this invention, through the inclusion of current detection, voltage detection, temperature detection, and logic judgment modules, avoids abnormalities in the target battery's discharge current, discharge voltage, and operating temperature during the discharge process, further preventing damage to the target battery.

[0129] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
