请参阅图1，本发明较佳实施方式的无线充电系统100包括充放电模块102、控制模块104及无线传输模块106。本实施方式中，该无线充电系统100与可充电电池300连接，并利用可充电电池300的电能为用电设备400充电。该用电设备400可为具备无线充电功能的电子装置，如手机，平板电脑，电子书等。Please refer to FIG. 1 , a wireless charging system 100 according to a preferred embodiment of the present invention includes a charging and discharging module 102 , a control module 104 and a wireless transmission module 106 . In this embodiment, the wireless charging system 100 is connected to the rechargeable battery 300 , and uses the electric energy of the rechargeable battery 300 to charge the electric device 400 . The electric device 400 can be an electronic device with a wireless charging function, such as a mobile phone, a tablet computer, an e-book, and the like.
该控制模块104与该充放电模块102连接，控制模块104例如是微控制单元(microcontrolunit，MCU)。该无线传输模块106与该控制模块104连接，可充电电池300可与充放电模块102连接。The control module 104 is connected to the charging and discharging module 102, and the control module 104 is, for example, a micro control unit (MCU). The wireless transmission module 106 is connected to the control module 104 , and the rechargeable battery 300 can be connected to the charging and discharging module 102 .
请结合图2，本实施方式中，该充放电模块102包括单片机108、弹簧开关110、模数转换单元(ADC)112及提示单元114。弹簧开关110、模数转换单元112及提示单元114均与单片机108连接。单片机108的使能端116与控制模块104的充放电使能管脚连接，用于接收控制模块的使能信号。Please refer to FIG. 2 , in this embodiment, the charging and discharging module 102 includes a single chip microcomputer 108 , a spring switch 110 , an analog-to-digital conversion unit (ADC) 112 and a prompt unit 114 . The spring switch 110 , the analog-to-digital conversion unit 112 and the prompt unit 114 are all connected to the microcontroller 108 . The enable terminal 116 of the single chip microcomputer 108 is connected to the charge and discharge enable pin of the control module 104 for receiving the enable signal of the control module.
该弹簧开关110用于检测该用电设备400是否接入该无线充电系统100并生成对应的充电开关信号。弹簧开关110可设置在充电底座(图未示)上，充电底座用于承载该用电设备400，当该用电设备400稳定地放置于充电底座上时，充电底座使该用电设备400能够闭合弹簧开关110，以触发无线充电系统100对用电设备400进行充电。可充电电池300可设置在充电底座内。The spring switch 110 is used to detect whether the electric device 400 is connected to the wireless charging system 100 and generate a corresponding charging switch signal. The spring switch 110 can be arranged on a charging base (not shown in the figure), and the charging base is used to carry the electric device 400. When the electric device 400 is stably placed on the charging base, the charging base enables the electric device 400 to Close the spring switch 110 to trigger the wireless charging system 100 to charge the electric device 400 . A rechargeable battery 300 may be disposed within the charging base.
例如，充电底座具有物理接口118，物理接口118可帮助用电设备400定位在充电底座上。弹簧开关110例如位于物理接口118内。在无线充电系统100的使用环境平稳的情况下，用电设备400放置在物理接口118时，能够将弹簧开关110闭合以触发无线充电系统100对用电设备400进行充电。For example, the charging base has a physical interface 118 that can help the powered device 400 to be positioned on the charging base. Spring switch 110 is located, for example, within physical interface 118 . When the use environment of the wireless charging system 100 is stable, when the electric device 400 is placed on the physical interface 118 , the spring switch 110 can be closed to trigger the wireless charging system 100 to charge the electric device 400 .
当用电设备400放入充电底座闭合弹簧开关110时，弹簧开关110生成第一充电开关信号，该第一充电开关信号表明该用电设备400接入该无线充电系统100。When the electric device 400 is put into the charging base and the spring switch 110 is closed, the spring switch 110 generates a first charging switch signal, which indicates that the electric device 400 is connected to the wireless charging system 100 .
单片机108用于判断该第一充电开关信号在设定时间段内是否稳定，若是，该单片机108生成表示该无线传输模块106输出电能至该用电设备400的第一充电控制信号。该控制模块104根据该第一充电控制信号控制该无线传输模块106输出电能至该用电设备400。输出的电能可来自可充电电池300。此时，控制模块104可根据第一充电控制信号，通过充放电使能管脚向单片机108发送放电的使能信号。单片机108根据该放电的使能信号将可充电电池300的电能通过无线传输模块106向外部传输。The single-chip microcomputer 108 is used to determine whether the first charging switch signal is stable within a set period of time, and if so, the single-chip microcomputer 108 generates a first charging control signal indicating that the wireless transmission module 106 outputs electric energy to the electric device 400 . The control module 104 controls the wireless transmission module 106 to output electric energy to the electric device 400 according to the first charging control signal. The output power can come from the rechargeable battery 300 . At this time, the control module 104 may send a discharge enable signal to the single-chip microcomputer 108 through the charge and discharge enable pin according to the first charge control signal. The single-chip microcomputer 108 transmits the electric energy of the rechargeable battery 300 to the outside through the wireless transmission module 106 according to the discharge enable signal.
例如，设定时间段为3秒，当用电设备400放入底座闭合弹簧开关110时，单片机108通过模数转换单元112判断弹簧开关110的电平信号由低变高，此时，若单片机108在之后的3秒内通过模数转换单元112持续检测该电平信号一直稳定在高电平，则单片机108判断用电设备400已成功接入无线充电系统100，即可进行充电了，并生成第一充电控制信号。控制模块104根据第一充电控制信号控制作为传输端的无线传输模块106的发射器和接收芯片同时开始工作，发射器的无线发射电路将一定频率的交流电以电磁波的形式向外幅射，通过电磁感应，作为接收端的用电设备400会产生一定的电流，从而将能量(电能)从传输端转移到接收端。用电设备400对接收到的电流进行处理后对用电设备400里的电池进行充电。无线充电系统100输出电能，处于开启状态。For example, the time period is set to 3 seconds. When the electrical equipment 400 is put into the base to close the spring switch 110, the single-chip microcomputer 108 judges that the level signal of the spring switch 110 changes from low to high through the analog-to-digital conversion unit 112. At this time, if the single-chip microcomputer 108 continues to detect that the level signal has been stable at a high level through the analog-to-digital conversion unit 112 within the next 3 seconds, then the single-chip microcomputer 108 judges that the electric device 400 has successfully connected to the wireless charging system 100, and it can be charged, and A first charging control signal is generated. The control module 104 controls the transmitter and the receiving chip of the wireless transmission module 106 as the transmission end to start working at the same time according to the first charging control signal. The wireless transmission circuit of the transmitter radiates the alternating current of a certain frequency in the form of electromagnetic waves, and through electromagnetic induction , the electric device 400 serving as the receiving end will generate a certain current, thereby transferring energy (electric energy) from the transmitting end to the receiving end. The electric device 400 charges the battery in the electric device 400 after processing the received current. The wireless charging system 100 outputs electric energy and is in an on state.
若单片机108判断该第一充电开关信号在设定时间段内不稳定，该单片机108生成表示保持该无线传输模块106停止输出电能至该用电设备400的状态的第三充电控制信号，该控制模块104根据该第三充电控制信号控制该无线传输模块106保持停止输出电能至该用电设备400的状态，也就是说，电平信号在该设定时间段内由高变低(或在设定时间内变化多次)，用电设备400尚未稳定接入无线充电系统100，控制模块104使无线传输模块106不工作，节约了不必要的电能消耗。此时，控制模块104可根据第三充电控制信号，通过充放电使能管脚向单片机108发送充电的使能信号。单片机108根据该充电的使能信号对可充电电池300进行充电。If the single-chip microcomputer 108 judges that the first charging switch signal is unstable within the set time period, the single-chip microcomputer 108 generates a third charging control signal indicating that the wireless transmission module 106 stops outputting electric energy to the electric device 400. The module 104 controls the wireless transmission module 106 to maintain the state of stopping outputting electric energy to the electric device 400 according to the third charging control signal, that is, the level signal changes from high to low within the set period of time (or within the set period of time). change multiple times within a certain period of time), and the electric device 400 has not been stably connected to the wireless charging system 100, the control module 104 disables the wireless transmission module 106 to save unnecessary power consumption. At this time, the control module 104 can send a charge enable signal to the single-chip microcomputer 108 through the charge and discharge enable pin according to the third charge control signal. The single-chip microcomputer 108 charges the rechargeable battery 300 according to the charging enable signal.
提示单元114用于提示用户该用电设备400的充电状态。该单片机108根据该充电控制信号用于控制该提示单元114提示该用户该用电设备400的充电状态。本实施方式中，提示单元114为蜂鸣器。The prompting unit 114 is used to prompt the user of the charging state of the electric device 400 . The single-chip microcomputer 108 is used to control the prompt unit 114 to prompt the user of the charging state of the electric device 400 according to the charging control signal. In this embodiment, the prompt unit 114 is a buzzer.
在上述两个情况中，单片机108根据第一充电控制信号，控制提示单元114提示用户该用电设备400已成功接入无线充电系统100并进行充电的状态，例如，单片机108可控制提示单元114连续发出两声较短″嘟″声来提示用户该用电设备400已成功接入无线充电系统100并进行充电的状态。In the above two cases, the single-chip microcomputer 108 controls the prompt unit 114 to remind the user that the electric device 400 has successfully connected to the wireless charging system 100 and is charging according to the first charging control signal. For example, the single-chip microcomputer 108 can control the prompt unit 114 Two short "beep" sounds are issued continuously to remind the user that the electric device 400 has been successfully connected to the wireless charging system 100 and is being charged.
单片机108根据第三充电控制信号，控制提示单元114提示用户该用电设备400没有成功接入充电系统100也没开始充电的状态，例如，单片机108可控制提示单元114发出一声较长″嘟″声来提示用户该用电设备400没有成功接入充电系统100也没开始充电的状态。因此，通过提示单元114提示用户，用户知道用电设备400是否开始充电，这样避免了用户以为用电设备400在充电但却没有充电的情况出现。同时，这样也能避免无线充电系统100非正常误判的情况出现，有利于用户对无线充电系统100的维持。According to the third charging control signal, the single-chip microcomputer 108 controls the prompt unit 114 to prompt the user that the electric device 400 has not successfully connected to the charging system 100 and has not started charging. A voice prompts the user that the electric device 400 has not been successfully connected to the charging system 100 and has not started charging. Therefore, by prompting the user through the prompt unit 114, the user knows whether the electric device 400 starts charging, which avoids the situation that the user thinks that the electric device 400 is charging but is not charging. At the same time, this can also prevent the wireless charging system 100 from misjudging abnormality, which is beneficial to the user's maintenance of the wireless charging system 100 .
在充电过程中，当用电设备400从充电底座脱离断开弹簧开关110时，弹簧开关110生成第二充电开关信号，该第二充电开关信号表明该用电设备400已断开与该无线充电系统100的连接。During the charging process, when the electric device 400 is detached from the charging base to disconnect the spring switch 110, the spring switch 110 generates a second charging switch signal, which indicates that the electric device 400 has been disconnected from the wireless charging. System 100 connections.
单片机108用于判断该第二充电开关信号在设定时间段内是否稳定，若是，该单片机108生成表示该无线传输模块106停止输出电能至该用电设备400的第二充电控制信号。该控制模块104根据该第二充电控制信号控制该无线传输模块106停止输出电能至该用电设备400。输出的电能可来自可充电电池300。此时，控制模块104可根据第二充电控制信号，通过充放电使能管脚向单片机108发送充电的使能信号。单片机108根据该充电的使能信号对可充电电池300进行充电。The single-chip microcomputer 108 is used to determine whether the second charging switch signal is stable within a set period of time, and if so, the single-chip microcomputer 108 generates a second charging control signal indicating that the wireless transmission module 106 stops outputting electric energy to the electric device 400 . The control module 104 controls the wireless transmission module 106 to stop outputting electric energy to the electric device 400 according to the second charging control signal. The output power can come from the rechargeable battery 300 . At this time, the control module 104 can send a charge enable signal to the single-chip microcomputer 108 through the charge and discharge enable pin according to the second charge control signal. The single-chip microcomputer 108 charges the rechargeable battery 300 according to the charging enable signal.
例如，设定时间段为3秒，当用电设备400从充电底座被取出断开弹簧开关110时，单片机108通过模数转换单元112判断弹簧开关110的电平信号由高变低，此时，若单片机108在之后的3秒内通过模数转换单元112持续检测该电平信号一直稳定在低电平，则单片机108判断用电设备400已成功断开与无线充电系统100的连接，即可停止无线传输模块106的工作。控制模块104控制作为传输端的无线传输模块106的发射器和接收芯片停止工作。无线充电系统100不再输出电能，进入关闭状态。For example, the time period is set to 3 seconds. When the electric device 400 is taken out from the charging base and the spring switch 110 is turned off, the single-chip microcomputer 108 judges that the level signal of the spring switch 110 changes from high to low through the analog-to-digital conversion unit 112. , if the single-chip microcomputer 108 continues to detect that the level signal has been stable at a low level through the analog-to-digital conversion unit 112 within the next 3 seconds, then the single-chip microcomputer 108 judges that the electric device 400 has successfully disconnected from the wireless charging system 100, that is The operation of the wireless transmission module 106 can be stopped. The control module 104 controls the transmitter and the receiving chip of the wireless transmission module 106 as the transmission end to stop working. The wireless charging system 100 no longer outputs electric energy, and enters into an off state.
若单片机108判断该第二充电开关信号在设定时间段内不稳定，该单片机108生成表示保持该无线传输模块106输出电能至该用电设备400的状态的第四充电控制信号，该控制模块104根据该第四充电控制信号控制该无线传输模块106保持输出电能至该用电设备400的状态，也就是说，电平信号在该设定时间段内由低变高(或在设定时间内变化多次)，用电设备400可能因外界的震动因素而暂时断开弹簧开关110后又重新闭合弹簧开关110，控制模块104控制无线传输模块106保持输出电能的状态，用电设备400能够在震动因素消除后继续充电，减少了用户的干预，因而提高了用户的人性化体验。无线充电系统100仍处于开启状态。If the single-chip microcomputer 108 judges that the second charging switch signal is unstable within the set time period, the single-chip microcomputer 108 generates a fourth charging control signal indicating that the state of keeping the wireless transmission module 106 outputting electric energy to the electric device 400, the control module 104 controls the wireless transmission module 106 to maintain the state of outputting electric energy to the electric device 400 according to the fourth charging control signal, that is, the level signal changes from low to high within the set time period (or within the set time period internal change multiple times), the electrical device 400 may temporarily disconnect the spring switch 110 due to external vibration factors and then close the spring switch 110 again, the control module 104 controls the wireless transmission module 106 to maintain the state of outputting electric energy, and the electrical device 400 can Continuing to charge after the vibration factor is eliminated reduces user intervention, thereby improving user-friendly experience. The wireless charging system 100 is still on.
在上述两个情况中，单片机108根据第二充电控制信号，控制提示单元114提示用户用电设备400已断开与无线充电系统100的连接且没有进行充电的状态，例如，单片机108可控制提示单元114发出一声较长″嘟″声来提示用户用电设备400已断开与无线充电系统100的连接且没有进行充电的状态。In the above two cases, the single-chip microcomputer 108 controls the prompt unit 114 to prompt the user that the electric device 400 has been disconnected from the wireless charging system 100 and is not charging according to the second charging control signal. For example, the single-chip microcomputer 108 can control the prompt The unit 114 emits a long "beep" sound to remind the user that the electric device 400 has been disconnected from the wireless charging system 100 and is not charging.
单片机108根据第四充电控制信号，控制提示单元114提示用户用电设备400保持充电的状态，例如，单片机108可控制提示单元114连续发出三声较短″嘟″声来提示用户用电设备400保持充电的状态。因此，通过提示单元114提示用户，用户知道用电设备400是否停止充电，这样避免了用户以为用电设备在充电但却没有充电的情况出现。同时，这样也能避免无线充电系统100非正常误判的情况出现，有利于用户对无线充电系统100的维持。According to the fourth charging control signal, the single-chip microcomputer 108 controls the prompting unit 114 to remind the user that the electric device 400 is in a state of charging. Stay charged. Therefore, by prompting the user through the prompt unit 114, the user knows whether the electric device 400 stops charging, which avoids the situation that the user thinks that the electric device is charging but is not charging. At the same time, this can also prevent the wireless charging system 100 from misjudging abnormality, which is beneficial to the user's maintenance of the wireless charging system 100 .
可以理解，在其它实施方式中，单片机108根据第四充电控制信号，也可控制提示单元114不提示用户，即当用电设备400在充电状态下，在设定时间段内因震动因素而产生的用电设备400断开弹簧开关110又闭合弹簧开关110，无线充电系统100也可不发出提示。It can be understood that, in other embodiments, the single-chip microcomputer 108 can also control the prompt unit 114 not to prompt the user according to the fourth charging control signal, that is, when the electric device 400 is in the charging state, within a set period of time due to vibration factors When the electrical device 400 turns off the spring switch 110 and then closes the spring switch 110 , the wireless charging system 100 may not issue a prompt.
另外，当无线充电系统100没有为用电设备400进行充电时，如该无线传输模块106处于停止输出可充电电池的电能至该用电设备400的状态，该充放电模块102可根据控制模块104发送的充电的使能信号对该可充电电池300进行充电。对可充电电池300进行充电的电能可来自于无线充电系统100所应用的设备上，例如，当无线充电系统100应用于汽车上时，对可充电电池300进行充电的电能可来自汽车的发电机。当可充电电池300没有为用电设备400充电时，且汽车的发动机处于开启状态，充放电模块102可利用发电机的电能为可充电电池300进行充电，为可充电电池300下次放电(为用电设备400充电)作准备。In addition, when the wireless charging system 100 is not charging the electric device 400, if the wireless transmission module 106 is in the state of stopping outputting the electric energy of the rechargeable battery to the electric device 400, the charging and discharging module 102 can according to the control module 104 The charging enable signal is sent to charge the rechargeable battery 300 . The electric energy for charging the rechargeable battery 300 can come from the device to which the wireless charging system 100 is applied. For example, when the wireless charging system 100 is applied to a car, the electric energy for charging the rechargeable battery 300 can come from the generator of the car. . When the rechargeable battery 300 is not charging the electric device 400, and the engine of the car is on, the charging and discharging module 102 can use the electric energy of the generator to charge the rechargeable battery 300, and discharge the rechargeable battery 300 next time (for charging with electric device 400) for preparation.
进一步地，为了检测可充电电池300的工作状态，该充放电模块102还包括温度检测单元120及电压检测单元122，温度检测单元120及电压检测单元122均与单片机108连接。Further, in order to detect the working state of the rechargeable battery 300 , the charging and discharging module 102 also includes a temperature detection unit 120 and a voltage detection unit 122 , both of which are connected to the single chip microcomputer 108 .
该温度检测单元120用于检测该可充电电池300的温度，该电压检测单元122用于检测该可充电电池300的充电电流及放电电流，该充放电模块102根据该温度、该充电电流或该放电电流用于停止该可充电电池300的充电或放电，或保持该可充电电池300的充电或放电的状态。The temperature detecting unit 120 is used to detect the temperature of the rechargeable battery 300, the voltage detecting unit 122 is used to detect the charging current and discharging current of the rechargeable battery 300, and the charging and discharging module 102 The discharge current is used to stop the charging or discharging of the rechargeable battery 300 , or maintain the charging or discharging state of the rechargeable battery 300 .

For the discharge current, the single chip microcomputer 108 is used to judge whether the discharge temperature is greater than the discharge temperature threshold and whether the discharge current is greater than the discharge current threshold. If the discharge temperature is greater than the discharge temperature threshold or the discharge current is greater than the discharge current threshold, the single-chip microcomputer 108 generates a discharge stop signal, and the control module 104 controls the single-chip microcomputer 108 to stop the discharge of the rechargeable battery 300 according to the discharge stop signal .

Whether the temperature threshold and the charging current are greater than the charging current threshold. If the charging temperature is greater than the charging temperature threshold or the charging current is greater than the charging current threshold, the microcontroller 108 generates a charge stop signal, and the control module 104 controls the microcontroller 108 to stop charging the rechargeable battery 300 according to the charge stop signal.
在电池的放电温度小于放电温度阀值及放电电流小于放电电流阀值的情况下，单片机108生成保持可充电电池300放电状态的保持放电信号，控制模块104根据该保持放电信号控制单片机108保持可充电电池300的放电状态。When the discharge temperature of the battery is less than the discharge temperature threshold and the discharge current is less than the discharge current threshold, the single-chip microcomputer 108 generates a hold discharge signal for maintaining the discharge state of the rechargeable battery 300, and the control module 104 controls the single-chip microcomputer 108 according to the hold discharge signal.
