Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The charging method provided by the application can be applied to an application environment shown in fig. 1. The application environment comprises a device to be charged 10 and a power supply device 20. The device to be charged 10 may be, but is not limited to, various notebook computers, smart phones, tablet computers, and portable wearable devices. The power supply device 20 may be various power adapters. The charging method may be applied to the device to be charged 10 or may be applied to a power adapter, which is not limited in detail in the embodiment of the present invention, and may be set according to actual situations.
In one embodiment, as shown in fig. 2, a charging method is provided, and the method is applied to the device to be charged in fig. 1, and the method includes the following steps:
In this embodiment, the current value of the first charging current is preset in the device to be charged in advance, and the first charging current is smaller than the rated charging current, which may be a current that makes the charging power reach the maximum value. When the charging signal is detected by the equipment to be charged, a control signal is sent to the power supply equipment, and the power supply equipment is controlled to charge the equipment to be charged by the first charging current. For example, the rated charging current is 9A, the first charging current is preset to be 6A, and when the charging signal is detected, the power adapter is controlled to charge the smart phone with the charging current of 6A. When the charging signal is detected, the device to be charged indicates that the power supply device starts to charge the device to be charged, for example, the device to be charged starts to be connected with the power adapter, and the device to be charged enters a charging initial stage.
Referring to fig. 3, the variation of the internal resistance value of the battery during the charging is shown. As can be seen from the figure, the internal resistance value of the battery is higher in the initial stage of charging, and also higher in the full stage, and lower in the intermediate stage of charging. This is because the lithium ion numbers of the positive and negative electrodes of the battery are maximally different in the initial charge stage and the full charge stage, and the internal polarization is maximized. In the prior art, the maximum charging current is usually used for charging the device to be charged, and the internal resistance value of the battery is relatively high in the initial stage of charging, and the temperature of the battery is rapidly raised by adopting a large-current charging battery, so that the maintenance time of the large current is relatively short. In the embodiment of the invention, when charging is started, the battery is charged with the first charging current lower than the rated charging current, and the rapid temperature rise of the battery can be avoided due to the large internal resistance value of the battery in the initial stage of charging and the small current charging.
In this embodiment, the charging speed cannot be increased when charging is performed with a small current, so that the first switching condition may be preset, in the charging process of the first charging current, the device to be charged detects whether the battery state satisfies the first switching condition, and if the battery state does not satisfy the first switching condition, charging with the first charging current is continued; and if the first switching condition is met, a control signal is sent to the power supply equipment, and the power supply equipment is controlled to charge the equipment to be charged with rated charging current. Wherein the first switching condition is a switching condition set according to the temperature rise and/or voltage of the battery. For example, the first switching condition includes that the temperature rise of the battery reaches 3 ℃ and/or the voltage reaches 1.0V, and when the temperature rise of the battery reaches 3 ℃ and/or the voltage reaches 1.0V, the power supply device is controlled to charge the device to be charged with the rated charging current.
For example, the rated charging current is 9A, the power adapter is controlled to charge the smart phone with the charging current of 6A, and if the temperature rise of the battery reaches 3 ℃ and/or the voltage of the battery reaches 1.0V during the charging process, the power adapter is controlled to charge the smart phone with 9A, see a charging current switching diagram shown in fig. 4, wherein the solid line is the temperature of the battery and the dotted line is the charging current.
Because the internal resistance value of the battery is lower in the middle stage of charging, the battery is charged by the rated charging current, namely the maximum charging current, and the battery is not heated up rapidly, so that the long-time high-current charging can be maintained, and the charging speed is further improved.
Optionally, the device to be charged is connected with the power supply device through a USB (Universal Serial Bus ) interface, the device to be charged sends a control signal to the power supply device through a data signal pin of the USB interface, and the power supply device charges the device to be charged through a power supply pin.
In the charging method, when a charging signal is detected, the equipment to be charged is controlled to be charged by a first charging current; and in the process that the equipment to be charged is charged by the first charging current, if the battery state of the equipment to be charged is detected to meet the preset first switching condition, controlling the equipment to be charged by the rated charging current. According to the embodiment of the invention, when charging is started, the battery is charged with the first charging current lower than the rated charging current, and the battery is prevented from being quickly heated up due to the fact that the internal resistance value of the battery is large in the initial stage of charging and the battery is charged with the small current; then, the battery is charged with the rated charging current, that is, the maximum charging current, at this time, the internal resistance value of the battery is lower than that in the initial stage of charging, and the battery is not rapidly warmed up even when charged with a large current, so that the charging with a large current can be maintained for a long time, and the charging speed is increased.
In another embodiment, the present embodiment relates to an optional process of detecting that the battery state of the device to be charged satisfies the preset first switching condition. On the basis of the embodiment shown in fig. 2 described above, the battery state includes: the specific implementation process of detecting whether the battery state of the device to be charged satisfies the preset first switching condition is described in detail below in a first manner and a second manner, respectively.
Mode one: acquiring the initial temperature and the current temperature of the battery; determining the temperature rise of the battery according to the initial temperature and the current temperature; if the temperature rise of the battery reaches the first preset temperature rise, the battery state of the equipment to be charged is detected to meet the first switching condition.
In this embodiment, when the device to be charged detects the charging signal, the initial temperature of the battery may be detected by the sensor and stored. In the process that the power supply equipment charges the equipment to be charged by the first charging current, the equipment to be charged detects the current temperature of the battery through the sensor; and determining the temperature rise of the battery according to the initial temperature and the current temperature of the battery, and judging whether the temperature rise of the battery reaches a first preset temperature rise or not. If the temperature rise of the battery reaches the first preset temperature rise, the condition that the battery state meets the first switching condition is determined to be detected, and then a control signal is sent to the power supply equipment, so that the power supply equipment charges the equipment to be charged with rated charging current. And if the temperature rise of the battery does not reach the first preset temperature rise, controlling the power supply equipment to continuously charge the equipment to be charged with the first charging current.
For example, when the first preset temperature rise is 3 ℃ and the smart phone detects a charging signal, the initial temperature of the battery is 23 ℃ through the sensor, and the power adapter is controlled to charge the smart phone with a charging current of 6A. The smart phone detects that the current temperature of the battery is 24 ℃ while charging with the charging current of 6A. Then, determining the temperature rise of the battery to be 1 ℃ according to the initial temperature and the current temperature of the battery, and continuously charging with the charging current of 6A when the temperature rise of the battery does not reach the first preset temperature rise, and continuously detecting the current temperature of the battery. When the current temperature of the battery is detected to be 26 ℃, determining that the temperature rise of the battery is 3 ℃ according to the initial temperature and the current temperature of the battery, and if the temperature rise reaches a first preset temperature rise, determining that the battery state is detected to meet a first switching condition, and controlling the power adapter to charge the smart phone by using the rated charging current of 9A.
Mode two: acquiring the current voltage of a battery; judging whether the current voltage reaches a preset voltage or not; if the current voltage reaches the preset voltage, the battery state of the equipment to be charged is detected to meet the first switching condition.
In this embodiment, when the power supply device charges the device to be charged with the first charging current, the current voltage of the battery is obtained, and if the current voltage of the battery reaches the preset voltage, it is determined that the battery state satisfies the first switching condition; if the present voltage of the battery does not reach the preset voltage, charging with the first charging current is continued. For example, the preset voltage is 1.0V, and the power adapter charges the smart phone with a charging current of 6A. The smart phone obtains the current voltage of the battery to be 0.5V, and controls the power adapter to continue charging with the charging current of 6A. When the smart phone obtains that the current voltage of the battery is 1.0V, the current voltage reaches the preset voltage, the fact that the battery state meets the first switching condition is determined, and the power adapter is controlled to charge the smart phone by using the rated charging current of 9A.
Alternatively, it is also possible to detect whether the battery state of the device to be charged satisfies the first switching condition by the current electric quantity of the battery. For example, the current electric quantity of the battery is obtained, and whether the current electric quantity reaches the preset electric quantity is judged; if the current electric quantity reaches the preset electric quantity, the battery state of the equipment to be charged is detected to meet the first switching condition. The current voltage of the battery can be converted into the current electric quantity of the battery according to the conversion relation between the electric quantity and the voltage; the current capacity of the battery can also be calculated according to the relation between the charging current and the capacity. The embodiment of the invention is not limited in detail, and can be set according to actual conditions.
Alternatively, the current temperature, the current voltage and the current of the battery can be detected in real time, or can be detected according to a preset detection period. The embodiment of the invention does not limit the detection period in detail, and can be set according to actual conditions.
In the step of detecting that the battery state of the equipment to be charged meets the preset first switching condition, when the temperature rise of the battery reaches the first preset temperature rise and/or the current voltage reaches the preset voltage, determining that the battery state of the equipment to be charged meets the first switching condition, and controlling the equipment to be charged to charge with rated charging current. According to the embodiment of the invention, the charging current can be switched according to the battery state, so that the battery temperature is not too high, the safe charging of the battery is ensured, the charging speed is ensured, and the charging efficiency is improved.
In another embodiment, on the basis of prolonging the charging time of the high current, the temperature of the battery needs to be controlled, so that the battery is prevented from being lost due to the fact that the temperature of the battery is too high. As shown in fig. 5, this embodiment relates to an alternative process of charging. On the basis of the embodiment shown in fig. 2, after the step 102, the following steps may be further included:
In this embodiment, in order to avoid damage to the device to be charged caused by the excessively high battery temperature during the charging process of the rated charging current, a second switching condition is preset, whether the battery state of the device to be charged meets the second switching condition is detected, if the battery state is detected to meet the second switching condition, a control signal is sent to the power supply device, and the power supply device is controlled to charge the device to be charged with the second charging current; wherein the second charging current is less than the nominal charging current; the second switching condition is a switching condition set according to the temperature rise and/or the temperature of the battery. That is, if the temperature rise or the temperature of the battery of the device to be charged reaches the switching condition, the charging current is reduced, so that the temperature of the battery is reduced or no longer increased, thereby avoiding the battery loss and prolonging the battery life.
Optionally, detecting that the battery state of the device to be charged meets the preset second switching condition may specifically include the following third and/or fourth modes:
mode three: acquiring the initial temperature and the current temperature of the battery; determining the temperature rise of the battery according to the initial temperature and the current temperature; if the temperature rise of the battery reaches the second preset temperature rise, the battery state of the equipment to be charged is detected to meet the second switching condition.
For example, the second preset temperature rise is 8 ℃, the smart phone detects that the initial temperature of the battery is 23 ℃ through the sensor, the current temperature is 28 ℃, the temperature rise of the battery is 5 ℃ when the temperature rise of the battery is determined, and the rated charging current is 9A when the temperature rise of the battery does not reach the second preset temperature rise. If the current temperature of the battery is detected to be 31 ℃, the temperature rise of the battery is determined to be 8 ℃, and the second preset temperature rise is reached, the power adapter is controlled to charge the smart phone by using the charging current of 6A.
Mode four: acquiring the current temperature of the battery; judging whether the current temperature of the battery reaches a preset temperature or not; if the current temperature of the battery reaches the preset temperature, the battery state of the equipment to be charged is detected to meet the second switching condition.
For example, if the preset temperature is 31 ℃, the smart phone detects that the initial temperature of the battery is 23 ℃ and the current temperature is 28 ℃ through the sensor, and the smart phone does not reach the preset temperature, the smart phone is continuously charged by the rated charging current 9A; and if the current temperature of the battery is detected to be 31 ℃, and the preset temperature is reached, controlling the power adapter to charge the smart phone by using the charging current of 6A.
It should be noted that the second charging current may be the same as the first charging current or different from the first charging current, which is not limited in detail in the embodiment of the present invention, and may be set according to practical situations.
Further, if the temperature of the battery continues to increase or the battery needs to be rapidly cooled during the process that the power supply device charges the device to be charged with the second charging current, the method may further include the following steps:
In this embodiment, if the temperature of the battery continues to increase or the battery needs to be rapidly cooled during the process of charging the power supply device with the second charging current as the device to be charged, a third switching condition may be preset, whether the battery state meets the third switching condition is detected, and if the battery state meets the third switching condition, a control signal is sent to the power supply device to control the power supply device to charge the device to be charged with the third charging current.
Wherein the third switching condition is a switching condition set according to the temperature rise and/or the temperature of the battery. Specifically, whether the temperature rise of the battery reaches a third preset temperature rise or not or whether the temperature of the battery reaches a preset temperature or not is detected; if the temperature rise of the battery reaches the third preset temperature and/or the temperature of the battery reaches the preset temperature, the power supply equipment is controlled to charge the equipment to be charged with the third charging current, as shown in fig. 4. The third charging current is smaller than the second charging current, namely, the charging current is further reduced, so that the temperature of the battery is reduced.
For example, the preset temperature is 31 ℃, when the current temperature of the battery is detected to be 31 ℃, the preset temperature is reached, and the power adapter is controlled to charge the smart phone with the charging current of 4A. For another example, the third preset temperature is raised to 8 ℃, the initial temperature of the battery is 23 ℃, the current temperature is 31 ℃, the temperature rise of the battery is 8 ℃, the third preset temperature rise is achieved, and the power adapter is controlled to charge the smart phone with 4A of charging current. The preset temperature in the third switching condition may be the same as or different from the preset temperature in the second switching condition, which is not limited in detail in the embodiment of the present invention, and may be set according to practical situations. Likewise, the third preset temperature rise may be the same as or different from the second preset temperature rise, which is not limited in detail in the embodiment of the present invention.
In this embodiment, the charging current is a present charging current provided by the power supply device to the device to be charged. When the current voltage of the battery reaches the charging cut-off voltage, a control signal is sent to the power supply equipment, and the power supply equipment is controlled to charge the equipment to be charged at a constant voltage by the charging cut-off voltage. For example, the charge cut-off voltage is 4.4V, and when the current voltage of the battery reaches 4.4V, the power adapter is controlled to charge the smart phone at a constant voltage of 4.4V.
When the power supply equipment uses the charging cut-off voltage as constant voltage charging of the equipment to be charged, the charging current provided by the power supply equipment for the equipment to be charged is gradually reduced, and when the charging current is detected to reach the charging cut-off current, a control signal is sent to the power supply equipment to control the power supply equipment to stop supplying power. For example, the charge cut-off current is 0.6A, the power adapter uses 4.4V as the constant voltage charge of the smart phone, and when the charge current of the power adapter gradually decreases to 0.6A, the power adapter is controlled to stop charging, see a charge current switching diagram shown in fig. 6, wherein a solid line is the temperature of the battery, and a dotted line is the charge current. The charge cut-off voltage is used for constant voltage charging of the equipment to be charged, so that the electric quantity of the battery is full.
In the charging method, if the battery state of the equipment to be charged is detected to meet the preset second switching condition in the process that the equipment to be charged is charged with the rated charging current, the equipment to be charged is controlled to be charged with the second charging current; in the process that the equipment to be charged is charged by the second charging current, if the battery state of the equipment to be charged is detected to meet the preset third switching condition, the equipment to be charged is controlled to be charged by the third charging current; if the current voltage of the battery reaches the charging cut-off voltage, controlling the equipment to be charged to charge at a constant voltage of the charging cut-off voltage; and in the charging process of the equipment to be charged with the charging cut-off voltage, if the charging current is detected to reach the charging cut-off current, controlling the equipment to be charged to stop charging. According to the embodiment of the invention, when the rated charging current is charged, the second charging current is switched to be charged according to the battery state, or the third charging current is switched to be charged, so that the equipment to be charged is prevented from being damaged due to the fact that the battery temperature is too high, and the service life of the equipment to be charged is prolonged. And after the current voltage of the power supply equipment reaches the charging cut-off voltage, the power supply equipment is controlled to charge the equipment to be charged at a constant voltage by using the charging cut-off voltage, so that the electric quantity of the battery is full.
