Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of energy storage power supply especially relates to a switch controller and energy storage power supply.
BACKGROUND
[0002] In the photovoltaic input source, the energy of the photovoltaic input source is greatly influenced by sunlight and temperature, resulting in the change of the power output by the load. When the photovoltaic input source supplies power to a DC load, if the load power is large, the voltage across the load may be pulled down to the lower limit voltage of the load appliance, resulting in the failure of the load. However, timely adjustment of the output power can enable the load to work at a suitable working voltage. Therefore, when the photovoltaic input source supplies power to the load, the mode of the photovoltaic input source needs to be switched according to the power of the load. The existing switching modes mainly include two types: manual control and software intelligent control.
[0003] For manual control, the control direction is determined by the person himself, and the initiative is relatively high. However, the person cannot switch the mode of the switch at all times, and the switch can only work in a certain mode during the time period when the person cannot watch over it. For some occasions where mode switching is required, this scheme is obviously deficient.
[0004] For software intelligent control switch switching, the control points for several mode switches are set by the person in advance, and the automatic switching of the mode of the controller can be completed through a certain sampling feedback circuit and a simple single-chip microcomputer. However, the initiative is relatively low, and it is difficult to modify the corresponding threshold value after it is set in advance. Moreover, the software controller can only switch by itself at any time. In addition, the software itself has a certain risk of failure, and the reliability is relatively low.

[0047] Please refer to Figure 1 , Figure 1 is a schematic diagram of an application scenario provided by an embodiment of the utility model, as Figure 1 shown, the application scenario 1 includes an energy storage power supply 100, a load 200 and a photovoltaic input source 300; the energy storage power supply 100 is connected with the photovoltaic input source 300, and the photovoltaic input source 300 is used to convert solar energy into electric energy and input the electric energy to the energy storage power supply 100. When the energy storage power supply 100 is connected with the load 200 (that is, when the energy storage power supply 100 is in a loaded state), the electric energy output by the photovoltaic input source 300 will be input to the load 200 through the energy storage power supply 100 to supply power to the load 200. And if the energy storage power supply 100 is in an unloaded state, the photovoltaic input source 300 will convert solar energy into electric energy and then input to the energy storage power supply 100 for storage.
[0048] Further, as Figure 1As shown, the energy storage power supply 100 further comprises a controller 10 and a switch controller 20; the switch controller 20 is connected with the load 200, and the switch controller 20 is further connected with the controller 10. The switch controller 20 is used for receiving the first driving signal or the second control signal output by the controller 10 when the energy storage power supply 100 is loaded, and starting to work according to the first driving signal or the second control signal, so as to input the input voltage of the photovoltaic input source 300 into the load 200, thereby making the energy storage power supply 100 supply power for the load 200.
[0049] In some embodiments, referring to Figure 2 , Figure 2 is a structural block diagram of a switch controller provided by the utility model embodiment, as Figure 2 shown, the switch controller 20 comprises a first switch control circuit 21, wherein the first switch control circuit 21 comprises a relay RLY1, a first manual control module 211 and a first automatic control module 212;
[0050] The coil end of the relay RLY1 is connected with a first power supply 51, and the coil end of the relay RLY1 is further connected with the first manual control module 211 and the first automatic control module 212; the first automatic control module 212 is further connected with the first manual control module 211; the connection end of the relay RLY1 is further connected with a load 200; and the first manual control module 211 and the first automatic control module 212 are further connected with a controller 10;
[0051] The first manual control module 211 is used for receiving a first driving signal and starting to work according to the first driving signal to control the coil end of the relay RLY1 to be powered on;
[0052] The first automatic control module 212 is used for receiving a first control signal when the first manual control module 211 works and stopping to work according to the first control signal; and
[0053] receiving a second control signal and controlling the coil end of the relay RLY1 to be powered on according to the second control signal.
[0054] In some embodiments, when the energy storage power supply 100 needs to be loaded, the connection end of the relay RLY1 needs to be controlled to be closed, so that the energy storage power supply 100 supplies power to the load 200. At this time, the coil end of the relay RLY1 can be controlled to be powered by the first automatic control module 212, so as to improve the accuracy of the switch controller 20. Specifically, when the controller 10 detects that the energy storage power supply 100 is connected to the load 200, the controller 10 outputs a second control signal to the first automatic control module 212, so that the first automatic control module 212 controls the relay RLY1 to be closed based on the second control signal, thereby outputting a voltage to the load 200, and thus the energy storage power supply 100 enters a loaded state.
[0055] In another embodiment, in order to improve the autonomy of the switch controller 20, the coil end of the relay RLY1 can also be controlled to be powered by the first manual control module 211. Specifically, when the energy storage power supply 100 needs to be in a loaded state, the controller 10 outputs a first drive signal to the first manual control module 211 by artificial control, so that the first manual control module 211 controls the coil end of the relay RLY1 to be powered based on the first drive signal, thereby controlling the connection end of the relay RLY1 to be closed, and thus the energy storage power supply 100 enters a loaded state.
[0056] It should be noted that in order to improve the safety and reliability of the energy storage power supply 100, after the controller 10 outputs the first drive signal to the first manual control module 211 by artificial control, the controller 10 also outputs a first control signal to the first automatic control module 212, so that the first automatic control module 212 stops working according to the first control signal, so that the first switch control circuit 21 works based on artificial control, thereby improving the reliability of the switch controller 20.
[0057] In yet another embodiment, please refer to Figure 3 , Figure 3 is a circuit diagram of a first switch control circuit provided by the embodiment of the utility model, as Figure 3 shown, the first manual control module 211 includes a diode D1, a resistor R1 and a switch tube Q1;
[0058] The control end of the switch tube Q1 is connected with the resistor R1, the first end of the switch tube Q1 is connected with the coil end of the relay RLY1, and the second end of the switch tube Q1 is used for grounding, the resistor R1 is connected with the anode of the diode D1 and the first automatic control module 212 respectively, and the cathode of the diode D1 is connected with the controller 10.
[0059] Specifically, when the energy storage power supply 100 is connected with the load 200, the switch tube Q1 receives the first driving signal output by the controller 10 through the resistor R1 and the diode D1, and is in a conductive state based on the first driving signal. When the switch tube Q1 is in a conductive state, the coil end of the relay RLY1 and the first power supply 51 (VCC) and the switch tube Q1 form a loop, so that the coil end of the relay RLY1 is powered, the connection end of the relay RLY1 is closed, and the energy storage power supply 100 starts to supply power to the load 200. It can be known that the first driving signal is a low-level signal, and the diode D1 is in a conductive state when the first driving signal is a low-level signal, and the switch tube Q1 is also in a conductive state.
[0060] Further, as shown in Figure 3 The first automatic control module 212 includes a resistor R2, a resistor R3, a resistor R4, a switch tube Q2, and a capacitor C1.
[0061] The control end of the switch tube Q2 is connected with the controller 10 through the resistor R2, and the control end of the switch tube Q2 is also grounded through the capacitor C1. The first end of the switch tube Q2 is connected with the first power supply 51 through the resistor R4, and the first end of the switch tube Q2 is also connected with the first manual control module 211. The second end of the switch tube Q2 is used for grounding, and the resistor R3 is connected with the capacitor C1 in parallel.
[0062] Specifically, when it is needed to control the coil end of the relay RLY1 to be powered through the first automatic control module 212, the switch tube Q2 receives the second control signal output by the controller 10 through the resistor R2, and is in a conductive state based on the second control signal. When the switch tube Q2 is in a conductive state, the switch tube Q1 is also in a conductive state, so that the coil end of the relay RLY1 is powered, and the energy storage power supply 100 starts to be loaded. It should be noted that when the controller 10 outputs the second control signal to the switch tube Q2, the switch tube Q1 is in a conductive state along with the switch tube Q2, so that the relay RLY1 is in a powered state, thereby making the first switch control circuit 21 not be controlled by human. Therefore, when it is needed to manually control the first switch control circuit 21, the controller 10 outputs the first driving signal to the switch tube Q1 and also outputs the first control signal to the switch tube Q2, so that the switch tube Q2 is closed based on the first control signal. At this time, the switch tube Q1 can start to work or stop to work based on the signal output by the controller 10.
[0063] In some embodiments, in order to improve the stability of the first power supply 51, as shown in Figure 2 The first switch control circuit 21 further comprises a protection module 213, which is connected with the first power supply 51 and the coil end of the relay RLY1 respectively.
[0064] The protection module 213 is used for processing the voltage output by the first power supply 51 when the first power supply 51 outputs voltage, so as to output stable voltage to the coil end of the relay RLY1.
[0065] Specifically, as shown in Figure 3 The protection module 213 comprises an inductor L1, a capacitor C2 and a capacitor C3. The inductor L1 is connected with the first power supply 51 and the first end of the capacitor C2 respectively. The first end of the capacitor C2 is connected with the coil end of the relay RLY1. The second end of the capacitor C2 is used for grounding. The capacitor C3 is connected with the capacitor C2 in parallel. When the first power supply 51 outputs power supply voltage, the inductor L1, the capacitor C2 and the capacitor C3 will filter the power supply voltage, so as to output stable voltage to the coil end of the relay RLY1.
[0066] It can be known that when the relay RLY1 starts to work based on the first manual control module 211 or the first automatic control module 212, the coil end of the relay RLY1 has current flowing through. When the energy storage power supply 100 stops to carry load, although the first manual control module 211 and / or the first automatic control module 212 will stop to work, there will still be some voltage margin in the coil end of the relay RLY1, so as to cause that the connection end of the relay RLY1 cannot be disconnected immediately. Based on this, as shown in Figure 2 The first switch control circuit 21 further comprises a discharge module 214, which is connected with the coil end of the relay RLY1. The discharge module 214 is used for discharging the residual voltage in the coil end of the relay RLY1 when the relay RLY1 stops to work.
[0067] In some embodiments, as shown in Figure 3 The discharge module 214 comprises a diode D2. The anode of the diode D2 is connected with the coil end of the relay RLY1. The cathode of the diode D2 is used for grounding. Specifically, when the first manual control module 211 and / or the first automatic control module 212 stop to work, the coil end of the relay RLY1 will form a loop with the diode D2, the capacitor C3 and the grounding end, so as to release the residual voltage in the coil end of the relay RLY1.
[0068] It should be noted that the energy of the photovoltaic input source 300 is affected by the sunlight irradiation and temperature, and the like, so the electric energy input from the photovoltaic input source 300 to the energy storage power supply 100 will also change accordingly. Therefore, when the energy storage power supply 100 is in a loaded state and the power of the load 200 is large, the voltage across the load 200 will be pulled down to the lower limit voltage of the load 200, thereby causing the load 200 to fail to work. Therefore, during the working process of the load 200, the working mode of the energy storage power supply 100 needs to be adjusted in real time to ensure that the load 200 can work stably within a suitable voltage range.
[0069] In some embodiments, as shown in FIG. 1, the switch controller 20 further comprises a second switch control circuit 22, wherein the second switch control circuit 22 comprises a relay RLY2, a second manual control module 221 and a second automatic control module 222. Figure 2
[0070] The relay RLY2 is connected in parallel with the relay RLY1, and the coil end of the relay RLY2 is further connected with the second manual control module 221 and the second automatic control module 222. The second automatic control module 222 is further connected with the second manual control module 221, and the second manual control module 221 and the second automatic control module 222 are further connected with the controller 10.
[0071] The second manual control module 221 is configured to receive a first driving signal and start working according to the first driving signal to control the coil end of the relay RLY2 to be powered on.
[0072] The second automatic control module 222 is configured to receive a first control signal when the second manual control module 221 works, and stop working according to the first control signal.
[0073] The second automatic control module 222 is configured to receive a first control signal when the second manual control module 221 works, and stop working according to the first control signal.
[0074] It can be understood that the structure and working principle of the second switch control circuit 22 are the same as those of the first switch control circuit 21, and will not be described herein.
[0075] In yet another embodiment, the working state of the energy storage power supply 100 includes a first working mode, a second working mode and a third working mode, wherein the first working mode is full load state, the second working mode is half load state, and the third working mode is empty load state. The load state of the energy storage power supply 100 is controlled in real time based on the illumination, temperature and other conditions of the photovoltaic input source 300, so as to make the load 200 work stably, and further improve the reliability of the energy storage power supply 100.
[0076] Specifically, when the first manual control module 211 and the second manual control module 221 both receive the first driving signal, or when the first automatic control module 212 and the second automatic control module 222 both receive the second control signal, the relay RLY1 and the relay RLY2 start working at the same time to enter the first working mode; and
[0077] When the first manual control module 211 or the second manual control module 221 receives the first driving signal, or when the first automatic control module 212 or the second automatic control module 222 receives the second control signal, the relay RLY1 or the relay RLY2 starts working to enter the second working mode.
[0078] When the first manual control module 211 and the second manual control module 221 both receive the second driving signal, or when the first automatic control module 212 and the second automatic control module 222 both receive the first control signal, the relay RLY1 and the relay RLY2 stop working at the same time to enter the third working mode.
[0079] It should be noted that the load condition of the energy storage power supply 100 is mainly determined by the closing condition of the relay RLY1 and the relay RLY2; wherein the closing condition of the relay RLY1 and the relay RLY2 includes automatic control and manual control two modes, when the load condition of the energy storage power supply 100 is switched through the relay RLY1 and the relay RLY2, the working state of the first manual control module 211, the second manual control module 221 is mainly controlled through the first driving signal / second driving signal output by the controller 10, and the working state of the first automatic control module 212, the second automatic control module 222 is controlled through the first control signal / second control signal output. When the relay RLY1 and the relay RLY2 are closed at the same time, it is considered that the energy storage power supply 100 is in a full load state, and if the relay RLY1 or the relay RLY2 is closed, it is considered that the energy storage power supply 100 is in a half load state; when the relay RLY1 and the relay RLY2 are both disconnected, it is considered that the energy storage power supply 100 is in an empty load state.
[0080] It can be known that in some embodiments, the switch controller 20 can include a third switch control circuit and a fourth switch control circuit according to actual needs, and the embodiment only takes two switch control circuits as an example.
[0081] In some embodiments, please refer to Figure 4 , Figure 4 It is a circuit diagram of a switch controller provided by the embodiment of the utility model, as Figure 4 shown, when the switch controller 20 is manually controlled, the controller 10 outputs the first driving signal to the switch tube Q1 and the switch tube Q3, the switch tube Q2 and the switch tube Q4 will receive the first control signal. At this time, the switch tube Q1 and the switch tube Q3 are in the conduction state, and the switch tube Q2 and the switch tube Q4 are in the cut-off state; when the switch tube Q1 and the switch tube Q3 are turned on, the coil end of the relay RLY1 and the coil end of the relay RLY2 are powered, so that the energy storage power supply is in a full load state. When the switch tube Q1 or the switch tube Q3 receives the first driving signal, the switch tube Q1 or the switch tube Q3 is turned on, so that the relay RLY1 or the relay RLY2 is closed, so that the energy storage power supply 100 enters the half load state. If the switch tube Q1 and the switch tube Q3 receive the second driving signal, the relay RLY1 and the relay RLY2 are disconnected, so that the energy storage power supply 100 is in an empty load state.
[0082] When the switch controller 20 is automatically controlled, the controller 10 outputs a second control signal to the switch tube Q2 and the switch tube Q4, the switch tube Q2 and the switch tube Q4 are turned on, so that the switch tube Q1 and the switch tube Q3 are also turned on, and the coil end of the relay RLY1 and the coil end of the relay RLY2 are electrified, and the energy storage power supply is in full load state. If the switch tube Q2 or the switch tube Q4 receives the second control signal, the relay RLY1 or the relay RLY2 is closed, and the energy storage power supply 100 enters the half load state. When the switch tube Q2 and the switch tube Q3 receive the first control signal, the relay RLY1 and the relay RLY2 are disconnected, and the energy storage power supply 100 is in an empty load state.
