Description

Technical Field

[0001] This utility model relates to the field of energy storage power technology, and in particular to a vertical portable energy storage power supply with tilt protection. Background Technology

[0002] With the rapid development of new energy technologies, energy storage power supplies are being used more and more widely, such as for home energy storage, industrial backup power, and electric vehicle charging. Vertical portable energy storage power supplies have gained popularity in the market due to their small footprint and ease of movement.

[0003] However, vertical portable energy storage units pose a risk of tipping over during movement or use. If tipped over, this can lead to safety issues such as damage, short circuits, and leaks to the internal battery or capacitor modules, and may even cause fires or explosions. Continuing to discharge or charge while tipped over can cause further damage to already compromised battery or capacitor modules, exacerbating the safety risks.

[0004] Currently, while some energy storage power supplies on the market have functions such as overcurrent protection, overvoltage protection, and overtemperature protection, they lack effective protection against tipping.

[0005] Therefore, it is necessary to improve existing vertical portable energy storage power technology to overcome its shortcomings. Utility Model Content

[0006] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a vertical portable energy storage power supply with tilt protection, so as to solve the problem that existing energy storage power supplies lack tilt protection function.

[0007] A vertical portable energy storage power supply with tipping protection includes a housing, an energy storage unit disposed within the housing, a power interface for connecting to an external power source or load, and a moving device disposed at the bottom of the housing. The power interface is electrically connected to the energy storage unit. The power storage unit further includes:

[0008] The tilt protection component installed inside the enclosure is used to monitor the tilting state of the vertical portable energy storage power supply and disconnect the electrical connection between the power interface and the energy storage unit when the vertical portable energy storage power supply tilts.

[0009] The tipping protection assembly includes a tilt sensor for detecting the tilt angle and a tipping protection circuit electrically connected to the tilt sensor. Both the tilt sensor and the tipping protection circuit are fixedly installed inside the housing.

[0010] Because energy storage power supplies contain high-energy storage units, there is a risk of internal short circuits, leakage, and even fire or explosion when they are tilted. By incorporating a tilt protection component, a tilt sensor monitors the tilt status of the energy storage power supply in real time. The tilt protection circuit quickly disconnects the electrical connection between the power interface and the energy storage unit when tilting is detected (i.e., the tilt angle exceeds a safe threshold). This prevents current from continuing to flow to the energy storage unit, thus avoiding secondary disasters such as internal short circuits and leakage caused by tilting, significantly improving the safety of the energy storage power supply during use.

[0011] Furthermore, the enclosure includes a frame and an outer shell mounted on the frame;

[0012] The moving device includes multiple wheels disposed at the bottom of the box;

[0013] The energy storage unit includes multiple battery modules or capacitor modules, which are arranged in an array and interconnected by connectors.

[0014] The battery module or capacitor module array is fixed on the frame.

[0015] The combination of frame and shell provides robust support and protection for the energy storage power source, preventing damage to internal components from external impacts. Wheels allow for easy movement, increasing usability. The energy storage unit employs an array of multiple battery modules or capacitor modules, interconnected via connectors. This modular design not only increases energy storage capacity but also facilitates assembly, maintenance, and replacement. Securely fixing the battery or capacitor module arrays to the frame ensures that the energy storage unit will not shift or collide within the enclosure during movement or tipping, further enhancing safety.

[0016] Furthermore, the tilt protection assembly also includes a sensor mounting bracket, which is fixedly connected to the frame, and the tilt sensor is mounted on the sensor mounting bracket.

[0017] Since the tilt sensor is a key component of the tilt protection function, its installation stability and accuracy directly affect the protection effect. By using a dedicated mounting bracket, it can be ensured that the tilt sensor will not loosen or shift when the energy storage power source is moved or subjected to vibration, guaranteeing its accurate detection of the tilt angle. Fixing the bracket to the frame, rather than directly to the housing, avoids the impact of housing deformation or damage on the tilt sensor, further improving its reliability and measurement accuracy.

[0018] Furthermore, the sensor mounting bracket has an L-shaped structure, and the sensor mounting bracket includes:

[0019] The first fixing part is used to fix the sensor mounting bracket to the frame inside the housing;

[0020] The second fixing part is provided with a groove, fixing hole and / or buckle that match the shape of the tilt sensor for fixing the tilt sensor.

[0021] The L-shaped structure is simple and practical, providing stable support. The first fixing part secures the bracket to the frame, ensuring its stability. The second fixing part, with its grooves, fixing holes, and / or snaps, fits tightly with the shape of the tilt sensor, achieving reliable fixation. This multi-layered fixing method (groove positioning, screw-in fixing holes, and snap-locking) effectively prevents the tilt sensor from loosening, falling off, or shifting direction during use, ensuring its long-term stable and accurate operation.

[0022] Furthermore, the sensor mounting bracket fixes the tilt sensor to the middle of one side of the housing.

[0023] Installing the tilt sensor in the middle of one side of the enclosure is an optimal position, proven through experiments and experience. This position ensures stable installation, effectively reflects the overall tilt angle of the energy storage power supply, is easier to implement, and offers better versatility for energy storage power supplies of different models and sizes.

[0024] Furthermore, the tilt sensor is an analog tilt sensor, used to output a voltage signal proportional to the tilt angle of the vertical portable energy storage power supply;

[0025] The tilt protection circuit also includes:

[0026] A comparator circuit is used to compare the voltage signal output by the analog tilt sensor with a preset reference voltage and output a comparison result signal.

[0027] A switching circuit, connected to the comparator circuit, is used to control the on / off connection between the power interface and the energy storage unit based on the comparison result signal.

[0028] Choosing an analog tilt sensor allows for a direct output of a voltage signal proportional to the tilt angle, eliminating the need for complex digital signal processing and simplifying circuit design. The tilt protection circuit employs a combination of a comparator and a switching circuit. The comparator compares the tilt sensor's output voltage with a preset reference voltage. When the tilt angle exceeds a threshold (corresponding to the reference voltage), the comparator outputs a flip signal, triggering the switching circuit to cut off the power supply. This circuit structure is simple, reliable, and has a fast response time, effectively providing tilt protection.

[0029] Furthermore, the comparator circuit includes:

[0030] Comparator chip;

[0031] An adjustable resistor is used to adjust the preset reference voltage;

[0032] The non-inverting input of the comparator chip is connected to the output of the analog tilt sensor;

[0033] The inverting input of the comparator chip is connected to the adjustable resistor;

[0034] The output of the comparator chip is connected to the switching circuit.

[0035] The comparator chip is the core of the comparator circuit, capable of accurately comparing the magnitudes of two input voltages. The adjustable resistor can be used to adjust the trigger threshold (i.e., the reference voltage) for tilt protection as needed. Connecting the non-inverting input of the comparator chip to the output of the tilt sensor, the inverting input to the adjustable resistor, and the output to the switching circuit creates a typical voltage comparator circuit. This circuit converts the analog signal from the tilt sensor into a switching signal, providing control signals for the switching circuit.

[0036] Furthermore, the switching circuit includes a relay or a MOSFET;

[0037] When the switching circuit includes a relay, the coil of the relay is connected to the output of the comparator circuit, and the normally open contact of the relay is connected in series in the electrical connection between the power interface and the energy storage unit.

[0038] When the switching circuit includes a MOSFET, the gate of the MOSFET is connected to the output of the comparator circuit, and the source and drain are connected to the circuit in a manner that disconnects the electrical connection between the power interface and the energy storage unit.

[0039] Relays offer excellent electrical isolation and can withstand high voltage and current, making them suitable for high-power energy storage power supplies. MOSFETs, on the other hand, offer advantages such as fast switching speed and low power consumption, making them suitable for small to medium-power energy storage power supplies. Regardless of the switching element used, the basic principle remains the same: when the signal output from the comparator circuit meets the trigger condition, the switching element turns on or off, thereby disconnecting the electrical connection between the power interface and the energy storage unit. Two optional solutions are provided, allowing this invention to flexibly select the appropriate switching device based on different power levels and application scenarios.

[0040] Furthermore, an interface panel is provided near the top of the enclosure, and the power interface is located on the interface panel, and the power interface does not extend beyond the top surface of the enclosure.

[0041] The interface panel is located on the top of the enclosure for easy user operation and connection of external devices. The power interface is positioned on the interface panel and does not protrude beyond the top surface of the enclosure, effectively preventing the power interface from colliding with the ground or other objects when the energy storage power supply is tilted, thus avoiding damage to the interface and improving the reliability and lifespan of the energy storage power supply.

[0042] Furthermore, the vertical portable energy storage power supply also includes a circuit board and a fixing plate, the circuit board is equipped with a BMS system, and the tilt protection circuit is installed on the circuit board;

[0043] The fixing plate is disposed between the energy storage unit and the interface panel. The fixing plate includes two oppositely arranged bent edges. The bent edges are bent along the length direction of the housing. One of the bent edges is bent towards the energy storage unit and fixedly connected to the frame. The other bent edge is bent towards the power interface and fixedly connected to the outer shell.

[0044] The fixing plate has multiple fixing studs on the side near the interface panel. The fixing studs are used to fix the circuit board and create a gap between the circuit board and the frame.

[0045] Integrating the tilt protection circuit and BMS system onto the circuit board improves circuit integration and reliability. The mounting plate isolates the circuit board from the energy storage unit and interface panel, preventing mutual interference, and provides stable support for the circuit board. The two bent edges of the mounting plate connect to the frame and housing respectively, enhancing the overall structural stability. The design of the mounting studs allows for easy fixation of the circuit board to the mounting plate while maintaining a certain gap between it and the frame, which facilitates heat dissipation.

[0046] The beneficial effects of this utility model are as follows:

[0047] This utility model provides a vertical portable energy storage power supply with tilt protection. Based on a conventional structure (box, energy storage unit, power interface, and moving device), this vertical portable energy storage power supply adds a tilt protection component housed within the box. This component consists of two core parts: a tilt sensor and a tilt protection circuit, which are electrically connected and work together. Vertical portable energy storage power supplies, due to their high center of gravity, are at risk of tipping over during movement or use. Tipping may lead to short circuits inside the energy storage unit, electrolyte leakage, or even more serious fires or explosions. The tilt protection component cuts off the power supply, preventing further energy input or output, thereby effectively avoiding or mitigating these secondary disasters. Traditional energy storage power supplies typically only have passive protection measures, such as overcurrent protection and overvoltage protection, which only provide protection after a fault occurs. The tilt protection component of this application is an active safety protection measure that can take action at the onset of a tipping fault, preventing potential damage.

[0062] Example 1

[0063] like Figures 1 to 5 As shown, this embodiment provides a vertical portable energy storage power supply with tipping protection.

[0064] The enclosure 100 includes a rectangular frame 110 and an outer shell 120 mounted on the frame 110. The frame 110 is composed of four U-shaped metal profiles with their openings facing outwards, forming an opening structure through snap-fits and latches, housing the energy storage unit 200.

[0065] The energy storage unit 200 is located inside the lower part of the housing 100 and consists of multiple lithium-ion battery modules 210 arranged in an array. Adjacent battery modules 210 are welded together by metal connecting pieces 220. The terminals of the multiple lithium-ion battery modules 210 face the same side. Epoxy boards 230 and EVA boards are provided on all six sides of the energy storage unit 200. The frame 110 surrounds the entire energy storage unit 200.

Two studs are provided at appropriate positions at both ends of each pressure strip 240 to form a more stable fixing structure with the outer shell 120. The two ends of the pressure strips 240 are fixedly connected to the frame 110. Cable tie bridges 250 are also provided on the frame 110 on both sides of the side where the wiring terminals of the energy storage unit 200 are located, for fixing the cables.

[0067] The power interface 300 is located on the interface panel 130 on the top of the enclosure 100. The interface panel 130 is a metal plate and is fixed to the outer casing 120 with screws. The top surface of the power interface 300 does not extend beyond the top surface of the enclosure 100. The power interface 300 includes a positive terminal and a negative terminal, which are located on the interface panel 130. The interface panel 130 also includes two DC air switches 131, a rocker switch 132, a communication interface 133, and a lamp assembly 134.

[0068] The mobile device 400 includes four casters 410 and a fixed base. The fixed base includes a base plate 420 and two mounting beams 430. The base plate 420 is fixedly connected to the frame 110 near the bottom by bolts or rivets. The two mounting beams 430 are arranged on both sides of the base plate 420 along the width direction of the box 100. The mounting beams 430 are integrally formed with the base plate 420 or welded to the base plate 420. The four casters 410 are respectively connected to the mounting beams 430 by bolts and fixed at the four corners of the bottom of the box 100.

[0069] The tipping protection assembly includes a tilt sensor 510, a sensor mounting bracket 530, a tipping protection circuit 520, and a reset button.

[0070] The tilt sensor 510 is an analog tilt sensor that outputs a 0-5V voltage signal.

[0071] The sensor mounting bracket 530 is an L-shaped metal bracket. The first fixing part of the sensor mounting bracket 530 is fixed to the vertical beam of the frame 110 in the middle of the left side of the housing 100 by two screws. The second fixing part of the sensor mounting bracket 530 has a groove and a buckle that match the shape of the tilt sensor 510. The tilt sensor 510 is embedded in the groove and fixed by the buckle.

[0072] The tipping protection circuit 520 is implemented using analog circuitry, including a comparator circuit and a switching circuit.

[0073] The comparator circuit includes a comparator chip, an adjustable resistor, and two other resistors.

[0074] The switching circuit includes a relay, an NPN transistor, and a diode.

[0075] The non-inverting input of the comparator chip is connected to the output of the tilt sensor 510, the inverting input is connected to an adjustable resistor, and the output is connected to the base of the transistor through a resistor. One end of the relay coil is connected to the collector of the transistor, and the other end is connected to the power supply, with a diode connected in reverse parallel across the coil. The normally open contact of the relay is connected in series in the electrical connection between the power interface 300 and the energy storage unit 200.

[0076] The reset button is a normally closed push-button switch. It is mounted on the interface panel 130, near the power switch. Alternatively, it can be mounted in other easily accessible locations within the housing 120.

[0077] The reset button is connected in series in the power supply circuit of the relay coil. One end of the reset button is connected to the collector of transistor T1, and the other end is connected to the coil of the self-locking relay.

[0078] The circuit board 600 integrates the BMS (Battery Management System) and the tilt protection circuit 520.

[0079] The fixing plate 700 is a metal plate and is disposed between the energy storage unit 200 and the interface panel 130. The fixing plate 700 has two opposing bent edges that are bent along the length of the housing 100. One bent edge is bent toward the energy storage unit 200 and is fixedly connected to the frame 110 by screws; the other bent edge is bent toward the interface panel 130 and is fixedly connected to the outer casing 120 by screws.

[0080] Multiple threaded studs are welded to the side of the mounting plate 700 near the interface panel 130. The circuit board 600 is fixed to the studs with screws and nuts, so that a certain gap is maintained between the circuit board 600 and the frame 110.

[0081] The working process of the vertical portable energy storage power supply in this embodiment includes:

[0082] 1. Normal working condition:

[0083] When the energy storage power supply is upright, the tilt sensor 510 outputs a low voltage, the comparator outputs a low level, the transistor is cut off, the relay is released, the normally open contact closes, and the circuit is completed.

[0084] 2. In the tilted state:

[0085] When the energy storage power supply tilts, the tilt sensor 510 outputs a high voltage, the comparator outputs a high level, the transistor conducts, the relay is energized, the normally open contact opens, and the circuit is broken.

[0086] 3. Reset operation:

[0087] Straighten the energy storage power source.

[0088] Press the reset button on interface panel 130. Since the reset button is normally closed, pressing it will disconnect the power supply circuit to the relay coil.

[0089] When the relay coil is de-energized, the armature is released, and the normally open contact closes again.

[0090] When the reset button is released, the power supply circuit of the relay coil is restored. However, since the tilt sensor 510 outputs a low voltage at this time, the comparator outputs a low level, the transistor is cut off, and the relay remains in the released state.

[0091] The energy storage power supply has resumed normal operation.

[0092] This embodiment of the vertical portable energy storage power supply employs a tilt protection component consisting of an analog tilt sensor, a comparator circuit, and a relay. When the energy storage power supply tilts, the tilt sensor 510 outputs a higher voltage signal, triggering the comparator circuit to output a high level, which in turn drives the relay to operate. Its normally open contact opens, directly cutting off the main circuit connection between the power interface 300 and the energy storage unit 200, effectively preventing current from continuing to flow to the energy storage unit 200 and avoiding serious safety accidents such as short circuits, leakage, or even fire and explosion of the battery module 210 that could occur due to tilting. Using a relay as a switching element provides excellent electrical isolation performance and can withstand high voltage and current, making it suitable for high-power energy storage power supply applications. Furthermore, this embodiment uses a self-locking relay and is equipped with a manual reset button. This design means that even after the energy storage power supply returns to an upright position following the tilt protection activation, manual intervention (pressing the reset button) is still required to restore power. This mandatory manual reset mechanism reminds the user to check for other problems with the energy storage power supply, preventing potential dangers in unknown situations and further improving safety.

[0093] Example 2

[0094] like Figures 1 to 6 As shown, this embodiment provides a vertical portable energy storage power supply with tilt protection function, including a housing 100, an energy storage unit 200, a power interface 300, a mobile device 400, and a tilt protection component.

[0095] The enclosure 100 includes a rectangular frame 110 and an outer shell 120 mounted on the frame 110. The frame 110 is made of aluminum alloy profiles connected by bolts, and the outer shell 120 is made of ABS engineering plastic and is fixed to the frame 110 by clips and screws.

[0096] The energy storage unit 200 is located inside the lower part of the housing 100 and consists of 16 lithium iron phosphate battery modules 210 arranged in a 4x4 array. Adjacent battery modules 210 are connected in series and parallel via copper busbars and bolts. The array of battery modules 210 is fixed to the bottom crossbeam of the frame 110 by an insulating bracket.

[0097] The power interface 300 is located on the interface panel 130 on the top of the enclosure 100. The interface panel 130 is made of aluminum alloy and is fixed to the outer shell 120 by rivets. The top surface of the power interface 300 does not extend beyond the top surface of the enclosure 100.

[0098] The moving device 400 includes two directional wheels and two omnidirectional wheels 410, which are fixed to the four corners of the bottom of the box 100 by bolts and washers, respectively.

[0099] The tipping protection assembly includes a tilt sensor 510 and a tipping protection circuit 520.

[0100] The tilt sensor 510 is an analog tilt sensor that outputs a 0-3.3V voltage signal.

[0101] The tipping protection circuit 520 is implemented using analog circuitry, including a comparator circuit and a switching circuit.

[0102] The comparator circuit includes a comparator chip, an adjustable resistor, and two other resistors.

[0103] The switching circuit uses an N-channel MOSFET. The gate of the MOSFET is connected to the output of the comparator chip, the source is directly grounded, and the drain is connected to the enable terminal of the BMS system of the energy storage unit 200 through a pull-up resistor.

[0104] The mounting plate 700 is an epoxy resin board and is disposed between the energy storage unit 200 and the interface panel 130. The mounting plate 700 has multiple through holes for the battery module 210 connection wires to pass through. The mounting plate 700 is fixed to the frame 110 by four insulating studs and nuts.

[0105] The circuit board 600 is directly fixed to the upper side of the fixing plate 700 by copper pillars and nuts, with no other connecting parts between them. The tilt sensor 510 is fixed to the center of the lower side of the fixing plate 700 by bolts.

[0106] The working process of the vertical portable energy storage power supply in this embodiment includes:

[0107] 1. Normal working condition:

[0108] The vertical portable energy storage power supply is in an upright position.

[0109] Analog tilt sensors detect very small tilt angles and output low voltage signals.

[0110] In the comparator circuit, the voltage at the non-inverting input (+) terminal of the comparator chip (i.e., the output voltage of the tilt sensor 510) is lower than the voltage at the inverting input (-) terminal (i.e., the reference voltage set by the adjustable resistor, for example, 2V).

[0111] The comparator chip outputs a low level.

[0112] The N-channel MOSFET (Q1) is turned off because the gate (G) voltage is lower than the turn-on voltage.

[0113] The MOSFET drain (D) is connected to the enable terminal of the 200BMS energy storage unit through a pull-up resistor. Since the MOSFET is turned off, the enable terminal is at a high level, the BMS system works normally, and the energy storage power supply works normally.

[0114] 2. Tilted state:

[0115] The vertical portable energy storage power source has tipped over.

[0116] As the tilt angle detected by the tilt sensor 510 increases, the output voltage signal rises.

[0117] When the tilt angle exceeds the preset threshold, the output voltage of the tilt sensor 510 is higher than the reference voltage at the inverting input of the comparator chip.

[0118] The comparator chip outputs a high level.

[0119] The N-channel MOSFET (Q1) is turned on because the gate (G) voltage is higher than the turn-on voltage.

[0120] When the MOSFET drain (D) voltage is pulled low, close to the source (S) voltage (ground potential), the enable pin of the BMS system goes low.

[0121] When the BMS system stops working, the electrical connection between the energy storage unit 200 and the power interface 300 is cut off, the energy storage power supply stops working, and the tipping protection is achieved.

[0122] 3. Automatic reset:

[0123] When the energy storage power supply is uprighted, the output voltage of the tilt sensor 510 decreases, falling below the comparator's reference voltage.

[0124] The comparator outputs a low level.

[0125] When the MOSFET (Q1) is turned off, the drain (D) voltage rises, the BMS system enable pin goes high, the BMS restarts, and the energy storage power supply automatically resumes operation.

[0126] This embodiment of the vertical portable energy storage power supply employs a tilt protection component composed of an analog tilt sensor, a comparator circuit, and a MOSFET. This embodiment utilizes the fast switching characteristics of the MOSFET to achieve tilt protection by controlling the enable terminal of the BMS system in the energy storage unit 200. When the energy storage power supply tilts, the output voltage signal of the tilt sensor 510 increases, triggering the comparator circuit to output a high level, which in turn drives the MOSFET to conduct, pulling down the enable terminal of the BMS system and stopping the BMS system from operating. This indirectly disconnects the electrical connection between the energy storage unit 200 and the power interface 300. Using MOSFETs as switching elements offers advantages such as fast switching speed, low power consumption, and low cost, making it suitable for small to medium power storage power supplies. More importantly, the circuit design of this embodiment ensures that after the tilt protection activates, once the energy storage power supply returns to an upright position, the output voltage of the tilt sensor 510 decreases, the MOSFET automatically turns off, the BMS system automatically resumes operation, and the energy storage power supply automatically resumes power supply without manual intervention. This automatic reset function simplifies user operation and improves ease of use, making it particularly suitable for applications requiring frequent movement or prone to slight tilting.
