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 control circuit 103 is connected to the standard battery access circuit 102 for monitoring the voltage of the connected universal battery 101. 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.

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.

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 and lower than the second set voltage, the control protection circuit 104 is disconnected, and the standard battery access circuit 102 is disconnected from the load 106. 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.

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.

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.

It can be understood that the transformer circuit 108 can be a separately provided circuit or integrated into other circuits.

For example, when the working voltage of the load is less than 3V when the power is supplied by the lithium battery, the voltage converting circuit 108 is a step-down circuit, and the output voltage of the lithium battery is stepped down and output; if the power is supplied by the dry battery, the load is operated. When the voltage is higher than 1.5 V, the transformer circuit 108 is a booster circuit, and the output voltage of the dry battery is boosted and output. When the operating voltage of the load is higher than 4.3V, the voltage converting circuit 108 can concentrate and boost the voltage of the dry battery or the lithium battery.

It can be understood that the transformer circuit 108 can be disposed in series with the monitoring control circuit 103 and the protection circuit 104, and can be connected to the input or output end of the protection circuit 104 for buck-boost processing. It can also be connected to the input or output of the monitoring control circuit 103 for buck-boost processing. Of course, the transformer circuit 108 can also be disposed without the protection circuit 104.

As shown in FIG. 4a, it is a fourth embodiment of the universal battery intelligent judgment control circuit of the present invention, which comprises a standard battery access circuit, a first connection circuit, a second connection circuit, a monitoring control circuit 400, a switch circuit, a load, and a charge. Circuits, etc.

The standard battery access circuit is connected to the first connection circuit, the second connection circuit, the monitoring control circuit 400, and the load, and the first connection circuit is connected to the standard battery access circuit, the monitoring control circuit 400, the switch circuit, the load, and the charging circuit. The two connection circuit is connected with the standard battery access circuit, the monitoring control circuit 400, the switch circuit, the load, the monitoring control circuit 400 and the standard battery access circuit, the first connection circuit, the second connection circuit, the switch circuit, the switch circuit and the A connection circuit, a second connection circuit, a monitoring control circuit 400, a charging circuit connection, a load is connected to the standard battery access circuit, the first connection circuit, and the second connection circuit, and the charging circuit is connected to the switch circuit.

The standard battery access circuit includes a battery compartment for accessing the universal battery 101. The output voltage of the universal battery 101 can be 0.9-4.2v, and can be selected according to different output voltages through the first connection circuit or the second connection circuit. An output voltage is supplied to the load.

The first connecting circuit is connected between the battery compartment and the load 601, and includes a diode 201, which can prevent the reverse direction of the current and protect the circuit. The diode 201 prevents the charging power source from supplying power and prevents the first switch 501 from reverse-conducting. When the first connecting circuit is turned on to the LED lamp 601, the output voltage of the battery compartment directly supplies power to the LED lamp 601.

The second connecting circuit is connected between the battery compartment and the load 601, and includes a DC-DC boosting circuit 301 and a diode 302. The boosting output of the universal battery is output to the load 601. Diode 302 prevents reverse current flow and acts as a protection circuit. It can be understood that when the load requires a lower voltage, the boost circuit can also be a buck circuit to adapt to different load requirements. Of course, the boosting circuit and the step-down circuit can also be simultaneously or alternatively disposed on the first connecting circuit or the second connecting circuit.

It can be understood that the diodes 201 and 301 can also be integrated in the switch having the bidirectional cut-off function to prevent the current from being reversed and protect the circuit.

In the present embodiment, the DC-DC boosting circuit 301 boosts the voltage to 3.3V to reach the operating voltage of the LED lamp, and the diode 302 prevents the reverse current from acting. When the second connection circuit is turned on to the LED lamp 601, the output voltage of the universal battery 101 passes through the DC-DC boosting circuit 301, and the output voltage that does not satisfy the operating voltage of the LED lamp 601 is raised to 3.3V, and the LED lamp 601 can be used. Normal power supply.

The monitor control circuit 400 includes a first comparator 401, a second comparator 402, and a reference voltage circuit that provides a reference voltage for the first comparator and the second comparator. The reference voltage circuit includes a first resistor 403, a second resistor 404, a third resistor 405, and a fourth resistor 406. It can be understood that the reference voltage circuit can also be other devices or circuits that provide a stable reference voltage, such as an LDO with a specific voltage output, a voltage reference source chip, a Zener diode, and the like.

The first comparator 401 monitors the output voltage of the universal battery 101. When the output voltage of the universal battery 101 is higher than the second set voltage (eg, 3v) to reach the operating voltage of the LED lamp 601, and the normal operating voltage of the lithium battery is satisfied, the first comparator 401 turns on the first switch 501, controls the first connection circuit to close, turns on the standard battery access circuit to the load, and simultaneously disconnects the second connection circuit.

The second comparator 402 monitors the output voltage of the universal battery 101. When the output voltage of the universal battery 101 is lower than the first set voltage (eg, 2v) and the operating voltage of the LED lamp 601 is not reached, the second comparator 402 outputs a control signal to be turned on. The second switch controls the second connection circuit to be closed, so that the output voltage of the universal battery 101 is boosted by the DC-DC boost circuit, and the output voltage can operate normally for the LED lamp 601.

It can be understood that the first comparator and/or the second comparator can also adopt a hysteresis comparator, a Schmitt trigger, or a comparator with a specific voltage trigger function, a voltage detecting chip, and a Schmitt trigger. , hysteresis comparator, voltage trigger component and circuit, etc., wherein the hysteresis comparator is used to reduce the sensitivity of the comparison voltage to enhance the interference capability, with hysteresis function; such as 2V as the reference source comparator, hysteresis comparator When it is lower than 2V, it will be converted to low level, but it will be converted to high level when it is higher than 2.2V; the Schmitt trigger function is the same as the hysteresis comparator. The voltage detection chip has a built-in specific voltage and the like.

Understandable. Monitoring control circuit 400 and/or second switch 502 can also be coupled to the input of transformer circuit 301.

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.

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.

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.

It can be understood that different circuits or chips can be used to achieve the same function.

The switching circuit includes a first switch 501, a second switch 502, a charging switch 503, and the like. The first switch 501 controls the on and off of the first connection circuit; the second switch 502 controls the on and off of the second connection circuit; and the charging switch 503 controls the on and off of the charging circuit. The first switch 501, the second switch 502, and the charging switch 503 may be MOS tubes or other switching tubes.

The load is LED lamp 601. Of course, it can be other loads; wherein the working voltage of the LED lamp is 3v, and when the voltage is lower than 3v, the LED lamp cannot work normally.

The charging circuit includes a charging power source 701, a charging switch 503, and the like. The voltage of the charging power source 701 is 4.2V. When the universal battery 101 is placed in the lithium battery, the comparator 402 turns on the charging switch 503, so that the charging power source 701 is turned on to the universal battery 101, and the current flows from the charging power source 701 to the universal battery 101.
