Description

Technical Field

[0001] This utility model relates to the field of power supply design, specifically to a portable energy storage power supply. Background Technology

[0002] With the development of new energy technologies, energy storage power supplies play an important role in production and daily life. In industrial settings, the use of impact-intensive industrial tools such as compressors and drill bits often occurs in remote and harsh environments. In these scenarios, industrial equipment cannot be connected to the AC power grid, preventing normal outdoor operation. In daily life, aging circuits can cause brief power outages, preventing many essential devices from starting. In related technologies, portable energy storage power supplies typically employ a two-stage converter circuit to achieve bidirectional DC-AC conversion. During discharge, the first-stage DC-DC converter boosts the battery voltage, while the second-stage DC-AC converter performs buck inversion. During charging, the second-stage AC-DC converter performs boost rectification, and the third-stage DC-DC converter performs buck charging of the battery. Both charging and discharging operations share a common filter, typically an LC filter. Due to the different charging and discharging conditions, a larger inductance value is needed during charging to reduce the current harmonics when the power bank is connected to the grid, while a smaller inductance value is needed during discharging to increase the load capacity of the power bank. The power bank uses the same filter for charging and discharging, which limits the performance of the power bank, and the front-end DC-DC converter limits the charging and discharging power.

It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0027] The "H-bridge," also known as the "H-type bridge circuit," is a common electronic circuit that converts DC voltage to AC voltage. The circuit's design resembles the letter "H," hence its name.

[0028] With the development of new energy technologies, energy storage power supplies play an important role in production and daily life. In industrial settings, the use of impact-intensive industrial tools such as compressors and drill bits often occurs in remote and harsh environments. In these scenarios, industrial equipment cannot be connected to the AC power grid, preventing normal outdoor operation. In daily life, aging circuits can cause brief power outages, preventing many essential devices from starting. In related technologies, portable energy storage power supplies typically employ a two-stage converter circuit to achieve bidirectional DC-AC conversion. During discharge, the first-stage DC-DC converter boosts the battery voltage, while the second-stage DC-AC converter performs buck inversion. During charging, the second-stage AC-DC converter performs boost rectification, and the third-stage DC-DC converter performs buck charging of the battery. Both charging and discharging operations share a common filter, typically an LC filter. Due to the different charging and discharging conditions, a larger inductance value is needed during charging to reduce the current harmonics when the power bank is connected to the grid, while a smaller inductance value is needed during discharging to increase the load capacity of the power bank. The power bank uses the same filter for charging and discharging, which limits the performance of the power bank, and the front-end DC-DC converter limits the charging and discharging power.

[0029] like Figure 1 As shown, this application provides a portable energy storage power source, which includes:

[0030] Energy storage module 110, which includes multiple cascaded power units (111 to 11N);

[0034] Specifically, such as Figure 1As shown, the energy storage module 110 includes N cascaded power units. Power units 11i invert the DC power stored in the battery Bati into AC power for the load, or rectify the AC power input from the grid into DC power to charge the relevant battery Bati. A first inductor module 120 is connected to the input / output ports of the energy storage module 110, providing a first inductance value during charging or discharging of the portable energy storage power supply.

[0039] In one embodiment of this application, such as Figure 4 As shown, the charging port is also connected in series between the second inductor module 140 and the external energy storage power supply. Specifically, the charging port of the portable energy storage power supply can be connected to the power grid or the discharge port of another portable energy storage power supply.

[0040] In one embodiment of this application, such as Figure 4 As shown, the portable energy storage power supply also includes a capacitor filter module 150. The input terminal of the capacitor filter module 150 is connected to the third port of the charge / discharge switching module 130, and the output terminal of the capacitor filter module 150 is connected to the discharge port.

The first end of the first capacitor C1 is connected to the normally closed contact of the first single-pole double-throw switch S1, and the second end of the first capacitor C1 is connected to the normally closed contact of the second single-pole double-throw switch S2.

[0041] In one embodiment of this application, such as Figure 4As shown, the first inductor module 120 includes a first inductor L1 and a second inductor L2. The first end of the first inductor L1 is connected to the first end of the input / output port of the energy storage module 110, that is, the first end of the first inductor L1 is connected to the second end of the first switch Q11 in the first power unit 111.

[0042] In one embodiment of this application, the second inductor module 130 includes a third inductor L3 and a fourth inductor L4.

The second end of the fourth inductor L4 is connected to the second end of the charging port.

[0043] like Figures 1 to 4 As shown, the working principle of the portable energy storage power supply provided in this application is as follows:

[0044] The working modes of portable energy storage power supplies include standby mode, power adjustment mode, discharge mode, charging mode and parallel mode. When the energy storage power supply is not in operation, it is in standby mode.

[0045] Standby mode: All power units stop working, with the four switches (Q1i to Q4i) on the H-bridge in the open state, and the two single-pole double-throw switches (S1, S2), the fifth switch S3 and the sixth switch S4 in the charge / discharge switching module 130 in the open state. The energy storage power supply will not discharge to the discharge port or input AC power from the charging port to charge the battery Vbati.

[0046] Power adjustment mode: When the energy storage module 110 includes 10 power units and can provide a rated power of 3600W and a peak power of 15KW, it can drive impact loads such as car wash machines and compressors within 15KW for a short period of time. If the preset time threshold is exceeded, overload protection will be activated. When the power required by industrial electrical appliances is less than the rated power provided by the energy storage power supply, for example, when 10 power units drive an AC load with a rated power of 1800W, without affecting its operation of driving the load, the first switch Q1i is turned on, the second switch Q2i is turned on, the third switch Q3i is turned off, and the fourth switch Q4i is turned off; or, the first switch Q1i is turned off, the second switch Q2i is turned off, the third switch Q3i is turned on, and the fourth switch Q4i is turned on. By controlling the sixth to tenth power units in a short-circuit state, the sixth to tenth power units are cut off, so that the energy storage module 110, which consists of 10 power units, only retains 5 power units to discharge to the outside, thereby driving the AC load with a rated power of 1800W to work normally without the need to replace the working power supply, which greatly reduces manpower consumption and expands the application range of energy storage power supply.

[0047] Discharge Mode: When the user needs the portable energy storage power supply to drive the AC load, the portable energy storage power supply enters the discharge mode from the standby mode. Before entering the discharge mode, the portable energy storage power supply will detect whether there is a fault in the voltage, current, and battery power of each power unit. If a fault is found, the portable energy storage power supply will remain in the standby mode. After detecting that there is no fault in each power unit, the first switch Q1i, the fourth switch Q4i, the second switch Q2i, and the third switch Q3i are alternately turned on. In the charge / discharge switching module 130, the first single-pole double-throw switch S1 is connected to the normally closed contact, and the second single-pole double-throw switch S2 is connected to the normally open contact. The energy storage module 110 performs discharge filtering through the first inductor module 120 and the capacitor filter module 150. The filter inductance is small, which improves the load-carrying capacity of the energy storage power supply.

[0048] Charging Mode: When the total charge of multiple batteries in the energy storage module is lower than the preset voltage threshold, the energy storage module needs to be charged. Before entering the charging mode, the portable energy storage power supply will detect the voltage, current, and battery charge status of each power unit. If a fault is found, the portable energy storage power supply will remain in standby mode; if there is no fault, the charging port will be connected to the power grid. In the charge / discharge switching module 130, the first single-pole double-throw switch S1 is connected to a normally open contact, the second single-pole double-throw switch S2 is connected to a normally open contact, and the first switch Q1i, the fourth switch Q4i, the second switch Q2i, and the third switch Q3i are alternately turned on to rectify the AC power input from the power grid into DC power. During charging, the first inductor module 120 and the second inductor module 140 are used for filtering to increase the inductance value and effectively reduce the current harmonic content.

[0049] Parallel operation: such as Figure 4 As shown, when the portable energy storage power supply is in discharge mode, the current portable energy storage power supply cannot drive the load. In the charge / discharge switching module 130, the first single-pole double-throw switch S1 is connected to the normally closed contact, the second single-pole double-throw switch S2 is connected to the normally closed contact, and the fifth switch S3 and the sixth switch S4 are closed. The peripheral energy storage power supply in discharge mode is connected to the current portable energy storage power supply through the charging port to realize parallel power supply processing to drive a larger AC load.

[0050] This application provides a portable energy storage power supply, which includes an energy storage module, two inductor modules, a charge / discharge switching module, a charging port, and a discharging port. The energy storage module includes multiple cascaded power units. The energy storage module uses multiple power units to invert DC power stored in multiple batteries into AC power for the load, or to rectify the AC voltage input from the grid into DC power to charge each battery. The output power of the energy storage power supply can be changed by adjusting the number of operating power units. The energy storage power supply is controlled to be in charging mode or discharging mode according to the connection status of the path in the charge / discharge switching module. When the energy storage power supply is discharging, the first inductor module filters the path from the energy storage module to the discharging port to improve the load-carrying capacity. Other energy storage power supplies can also be connected to enhance the load-carrying capacity. When the energy storage power supply is charging, the two inductor modules simultaneously filter the path from the charging port to the energy storage module to increase the inductance value of the charging current and reduce the harmonics of the grid-connected current. The portable energy storage power supply provided in this application uses cascaded power units to achieve multi-level AC output, which can reduce the inductance value under discharge conditions, improve the load-carrying capacity during discharge, and reduce dependence on battery packs through power units. The load-carrying power can be adjusted by regulating the operation of the power units or connecting other energy storage power supplies, thereby expanding the application range of the energy storage power supply. The inductance parameters during charging and discharging can be set independently to improve the performance of the power supply. During discharge, the discharge inductance is small, and the load-carrying capacity is enhanced. During charging, the charging inductance is large, and the current harmonic content is reduced.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
