具体实施方式Detailed ways
如图1所示,在本发明的通用电池101智能判断控制电路第一实施例的电路图中,包括标准电池接入电路102、以及监测控制电路103。其中,监测控制电路103与标准电池接入电路102连接,监测标准电池接入电路102的输出电压,并根据输出电压输出控制信号。As shown in FIG. 1, in the circuit diagram of the first embodiment of the universal battery 101 intelligent judgment control circuit of the present invention, a standard battery access circuit 102 and a monitoring control circuit 103 are included. The monitoring control circuit 103 is connected to the standard battery access circuit 102, monitors the output voltage of the standard battery access circuit 102, and outputs a control signal according to the output voltage.
其中,该标准电池接入电路102可以与通用电池101连接,接入工作电源。其中,通用电池101包括但不限于锂电池、干电池、镍氢电池等各种通用的标准电池。The standard battery access circuit 102 can be connected to the universal battery 101 and connected to the working power source. The general-purpose battery 101 includes, but is not limited to, various general-purpose standard batteries such as a lithium battery, a dry battery, and a nickel-hydrogen battery.

The monitoring, comparison, gate, threshold voltage and the like can be used to implement the monitoring control. For example, a lithium battery is judged to be higher than 2V, and is lower than 2V, and is judged to be a dry battery, a nickel-hydrogen battery, or the like; and a corresponding control signal is output according to what type of general-purpose battery 101 is determined to be accessed. For example, it is determined that a dry battery or the like directly supplies a circuit to supply power to the load, and it is determined that the lithium battery or the like needs to perform a second determination to determine whether or not to protect the reconnect circuit from supplying power to the load.
通过监测控制电路103监测标准电池接入电路102的输出电压,从而可以根据接入的通用电池101的输出电压,来输出对应的控制信号,从而可以实现多种不同通用电池101的互换使用,从而实现不同电池供电目的,提高了通用性、便捷性。The output voltage of the standard battery access circuit 102 is monitored by the monitoring control circuit 103, so that the corresponding control signal can be output according to the output voltage of the connected universal battery 101, so that the interchangeable use of a plurality of different universal batteries 101 can be realized.

The reminder circuit 105 can be an alarm, a prompt light, etc., and is reminded by various means such as sound and light.
可以理解的,该保护电路104、提醒电路105可以同时设置,也可以择一设置。It can be understood that the protection circuit 104 and the reminder circuit 105 can be set at the same time or alternatively.
该通用电池智能判断控制电路还包括通过保护电路104与标准电池接入电路102连接的负载106。在一些实施例中,该保护电路104包括由监测控制电路103控制通断的保护开关。其中,保护开关可以为机械开关、电子开关、开关管等各种开关。该监测控制电路103包括处理器,处理器与标准电池接入电路102连接,根据标准电池接入电路102的输出电压,控制保护开关的通断。可以理解的,处理器可以为现有各种独立的电压检测芯片及对应电路构 成,也可以为集成芯片化的处理电路,可以实现监测控制电路功能即可。The universal battery intelligent decision control circuit also includes a load 106 coupled to the standard battery access circuit 102 via the protection circuit 104. In some embodiments, the protection circuit 104 includes a protection switch that is controlled to be turned on and off by the monitoring control circuit 103. Among them, the protection switch can be various switches such as mechanical switches, electronic switches, and switch tubes. The monitoring control circuit 103 includes a processor coupled to the standard battery access circuit 102 to control the on and off of the protection switch in accordance with the output voltage of the standard battery access circuit 102. It can be understood that the processor can be composed of various independent voltage detecting chips and corresponding circuits, or can be integrated chip processing circuits, and can realize the functions of monitoring and controlling circuits.
监测控制电路103判断标准电池接入电路102的输出电压低于第一设定电压(例如2V)时,控制保护电路104闭合,接通标准电池接入电路102至负载106;此时判断为干电池,可正常给负载供电。When the monitoring control circuit 103 determines that the output voltage of the standard battery access circuit 102 is lower than the first set voltage (for example, 2V), the control protection circuit 104 is closed, and the standard battery access circuit 102 is turned on to the load 106; , can supply power to the load normally.
监测控制电路103判断标准电池接入电路102的输出电压高于第二设定电压(例如2.8V)时,控制保护电路104闭合,接通标准电池接入电路102至负载106;此时判断为锂电池,电池电压正常,可正常为负载供电。When the monitoring control circuit 103 determines that the output voltage of the standard battery access circuit 102 is higher than the second set voltage (for example, 2.8 V), the control protection circuit 104 is closed, and the standard battery access circuit 102 is turned on to the load 106; Lithium battery, battery voltage is normal, can supply power to the load normally.

At this time, it is judged to be a lithium battery, but for the purpose of lithium battery protection, power supply to the load is stopped.
可以理解的,监测控制电路103也可以设置第三设定电压,当低于第二设定电压保护电路104断开后,需高于第三设定电压才能正常给负载106供电。It can be understood that the monitoring control circuit 103 can also set a third set voltage. When the second set voltage protection circuit 104 is disconnected, it needs to be higher than the third set voltage to supply power to the load 106 normally.
进一步的,该通用电池101智能判断控制电路还可以包括通过保护电路104与标准电池接入电路102连接的充电电源107。当然,充电电源107和负载106可以择一设置。Further, the universal battery 101 intelligent judgment control circuit may further include a charging power source 107 connected to the standard battery access circuit 102 through the protection circuit 104. Of course, the charging power source 107 and the load 106 can be alternatively set.
监测控制电路103判断标准电池接入电路102的输出电压低于第一设定电压时,控制保护电路104断开,将标准电池接入电路102与充电电源107断开;When the monitoring control circuit 103 determines that the output voltage of the standard battery access circuit 102 is lower than the first set voltage, the control protection circuit 104 is disconnected, and the standard battery access circuit 102 is disconnected from the charging power source 107;
监测控制电路103判断标准电池接入电路102的输出电压高于第一设定电压时,控制保护电路104接通,将标准电池接入电路102与充电电源107接通。When the monitoring control circuit 103 determines that the output voltage of the standard battery access circuit 102 is higher than the first set voltage, the control protection circuit 104 is turned on, and the standard battery access circuit 102 and the charging power source 107 are turned on.

The voltage detection chip has a built-in specific voltage and the like.
可以理解的。监测控制电路400和/或第二开关502也可以连接于变压电路301输入端。Understandable. Monitoring control circuit 400 and/or second switch 502 can also be coupled to the input of transformer circuit 301.
如图4b所示,第一比较器和/或第二比较器还可以采用滞回比较器,在比较器的同向端(或反向端)增加一组分压电阻,从而在比较器反转时,会有一个滞回电压,实现延时反转功能,降低电压触发的灵敏度。以第二比较器为例,假设比较器反向端的基准电压为3V,假设同相端电阻A为100R,输出与同相端串接电阻为1500R。在本实施例中,当接入标准电池时,标准电池接入电路的输出电压高于第二设定电压时,控制保护电路闭合,接通标准电池接入电路至负载。当标准电池在使用时,其输出电压低于第二设定电压时,控制保护开关501断开;并且,在对标准电池充电提升电压时,由于比较器402具有滞回电压,使得比较器402的反向端的实际电压提升,从而标准电池的输出电压需要达到第三设定电压时,才能控制保护电路闭合,接通标准电池接入电路至负载。As shown in FIG. 4b, the first comparator and/or the second comparator may also adopt a hysteresis comparator, and add a group of voltage resistors at the same end (or opposite end) of the comparator, thereby When turning, there will be a hysteresis voltage to implement the delay inversion function to reduce the sensitivity of the voltage trigger. Taking the second comparator as an example, it is assumed that the reference voltage at the opposite end of the comparator is 3V, assuming that the non-inverting terminal resistor A is 100R, and the output and the non-inverting terminal series resistor are 1500R. In this embodiment, when the standard battery is connected to the standard battery, when the output voltage of the standard battery access circuit is higher than the second set voltage, the control protection circuit is closed, and the standard battery access circuit is turned on to the load. When the standard battery is in use, when its output voltage is lower than the second set voltage, the control protection switch 501 is turned off; and, when the standard battery is charged with the boost voltage, since the comparator 402 has a hysteresis voltage, the comparator 402 is caused. The actual voltage at the opposite end of the boost is such that when the output voltage of the standard battery needs to reach the third set voltage, the protection circuit can be closed and the standard battery access circuit can be connected to the load.
具体的:当标准电池接入电路接入3.7V电池,高于第二设定电压3V时,同相端电压3.7V,高于反相端2.8V,比较器输出高电平3.7V,控制保护开关501闭合。此时,电池电压,同相端与输出端通路,均为3.7V。Specific: When the standard battery access circuit is connected to the 3.7V battery, higher than the second set voltage of 3V, the non-inverting terminal voltage is 3.7V, higher than the inverting terminal 2.8V, and the comparator output is high level 3.7V, control protection Switch 501 is closed. At this time, the battery voltage, the non-inverting terminal and the output terminal are both 3.7V.
当电池电压低于3V(第二设定电压)时,比较器输出反转为低电平(接地)0V。控制保护开关501断开,此时,电池电压3V,输出端0V(接地)。受同相端电阻与输出端串接电阻的分压影响,同相端电压经计算得出实际电压变为2.8V。此时电池电压3V,同相端2.8V,反向端3V,输出端输出低电平。经计算,当电池电压达到3.2V(第三设定电压)时,同相端电压才达到3V,比较器输出高电平。因此,比较器在基准电压3V的情况下,实现3V关断,3.2V才会导通的滞回反馈信号,实现了延时反转功能,降低因电压波动带来的频繁开关动作风险。When the battery voltage is lower than 3V (second set voltage), the comparator output is inverted to low level (ground) 0V. The control protection switch 501 is turned off. At this time, the battery voltage is 3V and the output terminal is 0V (ground). Influenced by the voltage division of the non-inverting terminal resistor and the output terminal series resistor, the voltage at the same phase terminal is calculated to be 2.8V. At this time, the battery voltage is 3V, the non-inverting terminal is 2.8V, the reverse terminal is 3V, and the output terminal outputs a low level. It is calculated that when the battery voltage reaches 3.2V (the third set voltage), the voltage at the non-inverting terminal reaches 3V, and the comparator outputs a high level. Therefore, in the case of the reference voltage of 3V, the comparator realizes the hysteresis feedback signal that the 3V is turned off and the 3.2V is turned on, and the delay inversion function is realized, and the risk of frequent switching action due to voltage fluctuation is reduced.
可以理解的,可以采用不同的电路或芯片实现同样的功能。It can be understood that different circuits or chips can be used to achieve the same function.

如图9所示,在本发明的通用电池智能判断控制电路第九实施例的电路图中,包括标准电池接入电路、第一连接电路、第二连接电路、监测控制电路、开关电路、负载、充电电路等,其与第八实施例的区别在于使用保护芯片501替换第一开关501,其他元器件基本相同,故不赘述。其中,该保护芯片501具有充放电的电压比较功能,内置有基准源和比较器,其中比较器可以为滞回比较器、施密特触发器或其它类型的电压触发元件及电路。该保护芯片501可以为深度集成元件,例如可以将第一开关501和/或充电开关503集成其中,减少了外部开关;当然,也可以只输出控制信号、开关在外部,如电压检测芯片一样。As shown in FIG. 9, in the circuit diagram of the ninth embodiment of the universal battery intelligent judgment control circuit of the present invention, the standard battery access circuit, the first connection circuit, the second connection circuit, the monitoring control circuit, the switch circuit, the load, The charging circuit or the like differs from the eighth embodiment in that the first switch 501 is replaced with the protection chip 501, and the other components are substantially the same, and thus will not be described again. The protection chip 501 has a voltage comparison function of charging and discharging, and has a reference source and a comparator, wherein the comparator can be a hysteresis comparator, a Schmitt trigger or other types of voltage triggering elements and circuits. The protection chip 501 can be a deep integrated component. For example, the first switch 501 and/or the charging switch 503 can be integrated therein to reduce the external switch; of course, only the control signal can be output, and the switch is external, such as a voltage detecting chip.
在本实施例中,比较器401工作或设定电压如2v,比较器401监测通用电池101的输出电压,根据输出电压的电压值,控制第二开关502的开断。In the present embodiment, the comparator 401 operates or sets a voltage such as 2v, the comparator 401 monitors the output voltage of the universal battery 101, and controls the opening of the second switch 502 according to the voltage value of the output voltage.
当通用电池101接入一个干电池时,通用电池101的输出电压远低于LED灯601所需要的工作电压,比较器401未能达到工作或设定电压2v,而第二开关502处于闭合状态,输出电压连通第二连接电路给负载600正常供电;其中,输出电压经过DC-DC升压电路301后,输出电压提升到3.3V,连通到LED灯601时达到负载正常工作的电压,能够正常供电。When the universal battery 101 is connected to a dry battery, the output voltage of the universal battery 101 is much lower than the operating voltage required by the LED lamp 601, the comparator 401 fails to reach the operating or set voltage 2v, and the second switch 502 is in the closed state. The output voltage is connected to the second connecting circuit to supply power to the load 600 normally. After the output voltage passes through the DC-DC boosting circuit 301, the output voltage is raised to 3.3V, and when the LED lamp 601 is connected, the load reaches the normal working voltage, and the power can be normally supplied. .
当通用电池101接入一个锂电池时,锂电池的电压超过比较器401工作电压时,第二开关502关断,通用电池101连通保护芯片501,第一连接电路200连通到负载600,LED灯能正常工作。同时,充电电路700与标准电池接入电路100连通,同时充电开关503闭合,使得充电电源701可以输出充电电流对锂电池可以有充电的效果。When the universal battery 101 is connected to a lithium battery, when the voltage of the lithium battery exceeds the working voltage of the comparator 401, the second switch 502 is turned off, the universal battery 101 is connected to the protection chip 501, and the first connection circuit 200 is connected to the load 600, and the LED lamp Can work normally. At the same time, the charging circuit 700 is in communication with the standard battery access circuit 100, and the charging switch 503 is closed, so that the charging power source 701 can output a charging current that can charge the lithium battery.
上述锂电池的电压高于比较器401工作电压且低于锂电池保护芯片正常工作电压时,保护芯片501以及第二开关502断开,保护锂电池。When the voltage of the lithium battery is higher than the operating voltage of the comparator 401 and lower than the normal operating voltage of the lithium battery protection chip, the protection chip 501 and the second switch 502 are disconnected to protect the lithium battery.
可以理解的,第二开关502与DC-DC升压电路连接位置也可以调换,例如第二开关502可接于DC-DC升压电路输入端。It can be understood that the connection position of the second switch 502 and the DC-DC boosting circuit can also be switched. For example, the second switch 502 can be connected to the input end of the DC-DC boosting circuit.
优选地,监测控制电路通过监测标准电池接入电路的输出电压,只有输出电压到达一定值时,监测控制电路连通第一连接电路以及充电电路,同时断开第二连接电路。接入干电池时,通过第二连接电路升压的作用,使得负载正常工作。接入干电池或者锂电池都可以对负载进行正常供电。Preferably, the monitoring control circuit monitors the output voltage of the standard battery access circuit. When only the output voltage reaches a certain value, the monitoring control circuit communicates with the first connection circuit and the charging circuit, and simultaneously disconnects the second connection circuit. When the dry battery is connected, the load is boosted by the second connection circuit to make the load work normally. Normally, the load can be supplied with power by connecting a dry battery or a lithium battery.
