Description

Technical Field

[0001] The utility model relates to the technical field of power supplies, in particular to an energy storage power supply. Background Art

[0002] With the improvement of living standards, cars have become a necessity, and the number of cars in use has increased year by year. As a result, the problem of cars not being started for a long time or not being charged in time, resulting in the car being unable to start due to low starting batteries, has greatly increased. People have to take an electric car or find a tow truck to a repair shop to recharge, causing great inconvenience and expense.

[0003] The energy storage power supplies currently on the market generally only have conventional AC input charging, PV input charging, AC output, USB output, 120W car charger output and other functions. When the car starting battery is low, the user can use a 120W car charger to recharge the battery, but the ordinary batteries used in energy storage power supplies usually have a small rate, so the power is low and the charging speed is slow. When the capacity itself is insufficient, the charging capacity cannot meet the car starting requirements. There are also pure emergency starting power supplies on the market, but due to their small capacity and high cost, they can only meet emergency ignition or emergency power needs, and the application range is small.

[0040] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] Figure 1 A circuit block diagram of an energy storage power supply provided by an embodiment of the utility model, such as Figure 1 As shown, the energy storage power supply includes a main battery module 1, an electric energy output port 2 and an emergency start module. The main battery module 1 refers to a battery module of the energy storage power supply that is mainly used to meet the backup power demand. The emergency start module is a module used to provide power to the battery when the battery of the car is low so that the car can be ignited quickly, that is, a module used to start the car in an emergency.

[0043] The power load is a conventional device with power demand, the power output port 2 is used to connect the power load, the main battery module 1 is electrically connected to the power output port 2, and the main battery module 1 is used to supply power to the power load through the power output port 2, so the power demand of the conventional energy storage power supply can be met through the main battery module 1. Depending on the power load, different ports can be selected for the power output port 2, and the power output port 2 can be matched with the power load for connection, and the specific structure of the power output port 2 is not specifically limited here.

[0044] The emergency start module includes an emergency battery module 3 and an emergency output port 4. The emergency battery module 3 refers to a battery module used to provide electrical energy for the emergency start of the car. The emergency output port 4 is a port used to connect to the battery of the car. Different ports can be selected for the emergency output port 4 according to the type of battery of the car. As long as the emergency output port 4 can match the battery of the car for connection, the specific structure of the emergency output port 4 is not specifically limited here. The emergency battery module 3 is electrically connected to the emergency output port 4, so the emergency battery module 3 can output electrical energy to the battery through the emergency output port 4. When the car battery is charged, the car can be started, thereby realizing the emergency start of the car.

[0045] The battery discharge rate of the emergency battery module 3 is greater than the battery discharge rate of the main battery module 1, so the emergency battery module 3 can withstand the instantaneous impact current when the car is ignited and provide the electric energy required for emergency starting of the car.

[0046] The above scheme, by setting the main battery module 1, the power output port 2 and the emergency start module on the same energy storage power supply, the emergency start module includes the emergency battery module 3 and the emergency output port 4, and the battery discharge rate of the emergency battery module 3 is greater than the battery discharge rate of the main battery module 1. Therefore, the main battery module 1 of the energy storage power supply can output power to the power load through the power output port 2 to meet the conventional backup power demand, and the emergency battery module 3 can output power to the battery through the emergency output port 4 to meet the emergency start demand of the car, solving the problem that the energy storage power supply is difficult to meet the emergency ignition demand of the car.

[0047] In an optional embodiment of the utility model, the battery capacity of the main battery module 1 is greater than the battery capacity of the emergency battery module 3, so the main battery module 1 can meet the conventional backup power demand. Preferably, the main battery module 1 uses an ordinary battery with a larger capacity but a smaller rate, and the emergency battery module 3 uses a high-rate battery with a large rate but a small capacity, which not only meets the normal backup power needs, but also meets the function of emergency ignition of the car, increases the application scenarios of the energy storage power supply, and greatly facilitates the user. Because the emergency battery module 3 requires a high rate, the cost is 2 to 3 times that of an ordinary battery. If the energy storage power supply uses high-rate batteries, the cost of the whole machine will increase greatly. According to the actual use needs, a dual-battery compatible and complementary mode is adopted, and the capacity ratio is reasonably matched to reduce the cost of the whole machine.

[0048] In an optional embodiment of the utility model, the energy storage power supply further includes a first voltage conversion module 51, which refers to a module capable of adjusting the output voltage to achieve the required output voltage. Preferably, the first voltage conversion module 51 includes a DC-DC module, the main function of which is to convert the DC voltage into stable DC voltages of different levels to provide the required power for various electronic devices and circuits, so the required voltage conversion can be achieved through the DC-DC module.

[0049] The main battery module 1 is electrically connected to the input end of the first voltage conversion module 51, and the output end of the first voltage conversion module 51 is electrically connected to the emergency battery module 3, so the output voltage of the main battery module 1 can be converted into the charging voltage of the emergency battery module 3 through the first voltage conversion module 51, and the emergency battery module 3 can be charged at this time, so that when the emergency battery module 3 is low on power, it can be supplemented by the main battery module 1, ensuring that it has power in real time and is in a usable state at any time.

[0050] In an optional embodiment of the present utility model, as Figure 2 As shown, the number of emergency battery modules 3 is at least two, and each emergency battery module 3 is used to output a specific voltage value. Depending on the type of automobile battery, the specific voltage value output by the selected emergency battery module 3 is different. In a specific embodiment, a single emergency battery module 3 is used to output a 12V voltage. In other embodiments, the emergency battery module 3 may also output other voltage values, which are not specifically limited here.

[0051] The emergency start module also includes a switching control submodule 6, which is used to control different emergency battery modules 3 to be connected in series or in parallel, so that the emergency output port 4 outputs different voltage values. When different emergency battery modules 3 are connected in series, the voltage value output through the emergency output port 4 will be larger, and when different emergency battery modules 3 are connected in parallel, the voltage value output through the emergency output port 4 will be smaller. Therefore, different emergency battery modules 3 can be connected in series or in parallel through the switching control submodule 6, so that the emergency output port 4 can output different voltage values, thereby meeting the emergency start requirements of different vehicles.

[0052] Based on the above embodiments, Figure 2 and Figure 3 As shown, the switching control submodule 6 also includes a switch assembly and a switching control board 61, and the switch assembly includes at least one control switch 62; the control switch 62 is connected in series between an emergency battery module 3 and an emergency output port 4, so when the control switch 62 between the emergency battery module 3 and the emergency output port 4 is closed, the emergency battery module 3 and the emergency output port 4 are electrically connected, and when the control switch 62 is disconnected, the emergency battery module 3 and the emergency output port 4 are disconnected. Therefore, if the control switch 62 between each emergency battery module 3 and the emergency output port 4 is closed, all emergency battery modules 3 are connected in parallel. Optionally, the control switch 62 is connected in series between different emergency battery modules 3, so when the control switch 62 between two emergency battery modules 3 is closed, the two emergency battery modules 3 are connected in series.

[0053] The switch control board 61 is a control component for realizing voltage switching. The output end of the switch control board 61 is electrically connected to the controlled end of the control switch 62, so that the switch control board 61 can control the on and off of the control switch 62. When the control switch 62 is on, the circuit where the control switch 62 is located is on, and when the control switch 62 is off, the circuit where the control switch 62 is located is off. The switch control board 61 is used to output a switch control signal, which is an electrical signal that can control the control switch 62 to operate, and can be a voltage signal or a current signal. The control switch 62 is used to turn on or off under the control of the switch control signal. Through the on and off of different control switches 62, different emergency battery modules 3 will be connected in series or in parallel, so that the voltage output by the emergency output port 4 will be different.

[0054] Exemplarily, there are two emergency battery modules 3, namely a first emergency battery module 3a and a second emergency battery module 3b, and there are three control switches 62, namely a first control switch 62a, a second control switch 62b and a third control switch 62c.

[0055] The first emergency battery module 3 a includes a first positive output terminal 311 and a first negative output terminal 312 , the second emergency battery module 3 b includes a second positive output terminal 321 and a second negative output terminal 322 , and the emergency output port 4 includes an emergency output positive terminal 41 and an emergency output negative terminal 42 .

[0056] The first control switch 62a is connected in series between the first negative output terminal 312 and the second positive output terminal 321, so that when the first control switch 62a is turned off, the line between the first emergency battery module 3a and the second emergency battery module 3b is disconnected; when the first control switch 62a is turned on, the first emergency battery module 3a and the second emergency battery module 3b are connected in series.

[0057] The second control switch 62b is connected in series between the second positive output terminal 321 and the emergency output positive terminal 41, so that when the second control switch 62b is turned off, the second positive output terminal 321 and the emergency output positive terminal 41 are disconnected, and when the second control switch 62b is closed, the second positive output terminal 321 and the emergency output positive terminal 41 are electrically connected.

[0058] The third control switch 62c is connected in series between the first negative output terminal 312 and the emergency output negative terminal 42, so that when the third control switch 62c is turned off, the first negative output terminal 312 and the emergency output negative terminal 42 are disconnected, and when the second control switch 62b is closed, the first negative output terminal 312 and the emergency output negative terminal 42 are electrically connected.

[0059] Therefore, when the first control switch 62a is closed and the second control switch 62b and the third control switch 62c are opened, the first emergency battery module 3a and the second emergency battery module 3b are connected in series. When the first control switch 62a is opened and the second control switch 62b and the third control switch 62c are closed, the first emergency battery module 3a and the second emergency battery module 3b are connected in parallel. Therefore, by controlling the states of the first control switch 62a, the second control switch 62b and the third control switch 62c, the first emergency battery module 3a and the second emergency battery module 3b can be controlled to be connected in series or in parallel.

[0060] In an optional embodiment of the utility model, the emergency start module also includes a selection switch 63, which is a switch device that combines the functions of the tap selector and the switch and can carry and switch current. The selection switch 63 is used to receive the user's selection operation to output the first selection signal or the second selection signal. The first selection signal and the second selection signal are different electrical signals. The selection switch 63 has different gears. The user operates it to make it in different gears, and then outputs different signals, for example, the first selection signal is output when it is in one gear, and the second selection signal is output when it is in another gear. In a specific embodiment, the selection switch 63 is a knob switch, so that the selection switch 63 can be in different gears to output the first selection signal or the second selection signal by simply rotating the knob switch. In other embodiments, the selection switch 63 can also be other types of switches, which are not specifically limited here.

[0061] The switch control signal includes a first switch control signal and a second switch control signal. The output end of the selection switch 63 is electrically connected to the input end of the switch control board 61 , so the selection switch 63 can output the first selection signal or the second selection signal to the switch control board 61 .

[0062] The switch control board 61 is used to output a first switch control signal based on the first selection signal to disconnect the first control switch 62a and close the second control switch 62b. At this time, the first emergency battery module 3a and the second emergency battery module 3b are connected in parallel.

[0063] The switch control board 61 is used to output a second switch control signal based on the second selection signal to close the first control switch 62a and open the second control switch 62b and the third control switch 62c. At this time, the first emergency battery module 3a and the second emergency battery module 3b are connected in series.

[0064] Therefore, the user only needs to operate the selection switch 63 to make the emergency output port 4 output different voltage values ​​according to actual needs, so as to be used for ignition of different vehicle models.

[0065] In an optional embodiment of the present utility model, as Figure 2 and Figure 3 As shown, the selection switch 63 is also used to receive a user's selection operation to output a third selection signal; the switching control board 61 is used to output a second switch control signal based on the third selection signal when the battery voltage is greater than the voltage threshold, and output a first switch control signal when the battery voltage is less than or equal to the voltage threshold.

[0066] Among them, the voltage of the car's battery is the voltage required for the car to start, and the voltage threshold can be selected between the first emergency battery module 3a and the second emergency battery module 3b in series and in parallel, that is, the voltage threshold is greater than the voltage value of the first emergency battery module 3a and the second emergency battery module 3b in parallel, and less than the voltage value of the first emergency battery module 3a and the second emergency battery module 3b in series. Therefore, when the switch 63 of the switching control board 61 outputs the third selection signal, it can automatically connect the first emergency battery module 3a and the second emergency battery module 3b in series or in parallel according to the voltage of the battery, which is used for ignition of different models of cars.

[0067] In a specific embodiment, the voltages of the first emergency battery module 3a and the second emergency battery module 3b are both 12V, the voltage threshold is selected to be 16V, and the selection switch 63 outputs a first selection signal when it is in the first gear, outputs a second selection signal when it is in the second gear, and outputs a third selection signal when it is in the third gear. Since switches with multiple gears are common switches, the specific structure of the selection switch 63 is not specifically limited here.

[0068] When the user operates the selection switch 63 to place it in the first gear, the first emergency battery module 3a and the second emergency battery module 3b are connected in parallel, and the emergency output port 4 outputs a 12V voltage. When the user operates the selection switch 63 to place it in the second gear, the first emergency battery module 3a and the second emergency battery module 3b are connected in series, and the emergency output port 4 outputs a 24V voltage. When the user operates the selection switch 63 to place it in the third gear, the switching control board 61 will automatically connect the first emergency battery module 3a and the second emergency battery module 3b in series or in parallel according to the voltage of the battery. When the voltage of the battery is greater than 16V, the first emergency battery module 3a and the second emergency battery module 3b are controlled to be connected in series to output a 24V voltage; when the voltage of the battery is less than or equal to 16V, the first emergency battery module 3a and the second emergency battery module 3b are controlled to be connected in parallel to output a 12V voltage; therefore, 12V or 24V can be output according to actual needs for ignition of different vehicle models.

[0069] In an optional embodiment of the present utility model, as Figure 2As shown, the power output port 2 includes an AC output port 21, the energy storage power supply also includes an inverter module 7, the main battery module 1 is electrically connected to the DC end of the inverter module 7, and the AC end of the inverter module 7 is electrically connected to the AC output port 21; wherein the inverter module 7 is a module that converts a DC power supply into a power supply that can be used by an AC device. The AC output port 21 is a port for the energy storage power supply to output AC power, so the AC output port 21 is used to connect an AC load, which is a device that works with AC power. Since the power output by the main battery module 1 is usually DC power, the DC power output by the inverter module 7 can be converted into AC power, and then the AC load is powered by the AC output port 21.

[0070] On the basis of the above embodiment, the inverter module 7 includes a bidirectional inverter, and the AC end of the bidirectional inverter is also used to connect to the mains; the bidirectional inverter (BIC) is a power electronic device that can convert DC power into AC power and realize power transmission in two directions. The bidirectional inverter can be used to transmit power from a battery system or other DC power source to an AC power grid, and can also transmit power from an AC power grid to a battery system or other DC loads. Therefore, the mains can charge the main battery module 1 with a bidirectional inverter, and the main battery module 1 can also power the AC load through the bidirectional inverter.

[0071] In an optional embodiment of the utility model, the energy storage power supply further includes a maximum power point tracking module 8, and the maximum power point tracking module 8 is electrically connected to the main battery module 1. The maximum power point tracking module 8 (MPPT for short) is a device that can effectively store the direct current generated by the solar panel in the battery by adjusting the working state of the electrical module so that the photovoltaic panel can output more electrical energy. The maximum power point tracking module 8 is used to connect to photovoltaic (PV), so that the main battery module 1 can be charged by photovoltaic through the maximum power point tracking module 8.

[0072] In an optional embodiment of the present invention, the power output port 2 includes a DC output port 22, which is a port for the energy storage power supply to output DC power, so the DC output port 22 is used to connect a DC load, which is a device that works with DC power.

[0073] The energy storage power supply also includes a second voltage conversion module 52, the main battery module 1 is electrically connected to the input end of the second voltage conversion module 52, and the output end of the second voltage conversion module 52 is electrically connected to the DC output port 22. The second voltage conversion module 52 refers to a module that can adjust the output voltage to achieve the required output voltage. Preferably, the second voltage conversion module 52 includes a DC-DC module, and the main function of the DC-DC module is to convert the DC voltage into stable DC voltages of different levels to provide the required power supply for various electronic devices and circuits, so the required voltage conversion can be achieved through the DC-DC module. Since the DC voltage required by different DC loads may be different, the voltage output by the main battery module 1 can be converted into the working voltage of the DC load through the second voltage conversion module 52 to power different DC loads.

[0074] Preferably, the DC output port 22 includes at least one of a USB port and a car charger port.

[0075] In an optional embodiment of the present invention, the energy storage power supply further includes a display screen 53, which is a display tool that displays certain electronic files on the screen through a specific transmission device. Therefore, the parameter status of the energy storage power supply can be displayed through the display screen 53.

[0076] In an optional embodiment of the present utility model, the energy storage power supply further includes a power button 54, wherein the power button 54 is a button for controlling the power on and off of the energy storage power supply.

[0077] Preferably, the energy storage power supply further includes a control panel 5, and a power button 54 and a display screen 53 are both arranged on the control panel.

[0078] In an optional embodiment of the utility model, the main battery module 1 and / or the emergency battery module 3 are connected to a battery management system 9.

In a specific embodiment, the main battery module 1 and each emergency battery module 3 are connected to a battery management system 9 to manage and protect their own charging and discharging.

[0079] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps.
