Abstract
Description
Technical Field
[0001] The utility model relates to the field of electricity, in particular to a circuit and a charging and swapping cabinet for automatically backing up power after a power-off of a charging and swapping cabinet. Background Art
[0002] At present, with the development of society, there are more and more shared charging and swapping cabinets, which are convenient for battery swapping for private electric vehicles, food delivery electric vehicles, and errand running. However, the battery swapping cabinets may also experience power outages, and riders cannot swap batteries when they arrive at the cabinets, resulting in delivery delays. The backup power function also plays an important role. When it comes to solving this problem, the backup power function is the key content that needs to be considered.
[0003] Currently, the backup power circuits on the market all use a separate backup power board and battery, which requires separate software logic and requires reserving installation locations for two products, increasing the design difficulty and product installation time. Utility Model Content
[0004] In order to solve the above technical problems, the utility model proposes a circuit for automatically backing up power after a power failure in a charging and swapping cabinet.
[0005] The purpose of the utility model is achieved through the following technical solutions:
[0006] A circuit for automatically backing up power after a power failure in a charging and swapping cabinet, comprising a DC / DC circuit U1, wherein an input end of the DC / DC circuit U1 is electrically connected to no less than two anti-reverse connection circuits, each of which is electrically connected to a battery charging interface in a battery compartment of the charging and swapping cabinet, and an output end of the DC / DC circuit U1 is electrically connected to a power supply port CN1 of the charging and swapping cabinet.
[0007] As a further improvement, the anti-reverse connection circuit includes a first Schottky diode D1 and a third Schottky diode D3; the positive electrode of the first Schottky diode D1 is electrically connected to the positive electrode of the battery charging interface, and the negative electrode is electrically connected to the positive electrode of the input end of the DC / DC circuit U1; the negative electrode of the third Schottky diode D3 is electrically connected to the negative electrode of the battery charging interface, and the positive electrode is electrically connected to the negative electrode of the input end of the DC / DC circuit U1.
[0008] As a further improvement, the anode of the first Schottky diode D1 is electrically connected to the anode of the battery charging interface through the first fuse FUS1.
[0009] A charging and swapping cabinet is provided, wherein the circuit as described above is installed inside the charging and swapping cabinet for automatically backing up power after the charging and swapping cabinet is powered off.
[0010] The beneficial effects of the utility model are:
[0011] The utility model uses the battery charged in the charging and swapping cabinet as a backup power supply. When the mains power of the charging and swapping cabinet is cut off, the battery will reverse as a charging power supply and step down the voltage to the voltage required by the cabinet control through the DC / DC circuit to power the cabinet control, including speakers, display screens, cameras and other equipment. The circuit structure is simple, and no separate software control logic is required, and a location for a backup battery is reserved. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The present invention is further described with reference to the accompanying drawings, but the contents in the accompanying drawings do not constitute any limitation to the present invention.
[0013] Figure 1 This is a circuit diagram of the utility model. DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and examples.
[0015] Example 1
[0016] like Figure 1 A circuit for automatically backing up power after a power outage in a charging and swapping cabinet is shown, comprising a DC / DC circuit U1, wherein the DC / DC circuit U1 is electrically connected to a battery charged in the charging and swapping cabinet through a plurality of anti-reverse connection circuits.
[0017] For example, the reverse connection protection circuit for the first battery includes a first Schottky diode D1 and a third Schottky diode D3; the anode of the first Schottky diode D1 is electrically connected to the anode of the second battery charging interface CN2 through the first fuse FUS1, and the cathode is electrically connected to the anode of the input end of the DC / DC circuit U1; the cathode of the third Schottky diode D3 is electrically connected to the cathode of the second battery charging interface CN2, and the cathode is electrically connected to the cathode of the input end of the DC / DC circuit U1.
[0018] The anti-reverse connection circuit of the second battery includes a second Schottky diode D2 and a fourth Schottky diode D4; the anode of the second Schottky diode D2 is electrically connected to the anode of the third battery charging interface CN3 through the second fuse FUS2, and the cathode is electrically connected to the anode of the input end of the DC / DC circuit U1; the cathode of the third Schottky diode D4 is electrically connected to the cathode of the third battery charging interface CN3, and the cathode is electrically connected to the cathode of the input end of the DC / DC circuit U1.
[0019] It is undoubtedly inferred that the third battery, the fourth battery ... the nth battery can also be electrically connected through the same anti-reverse connection circuit.
[0020] In this way, when the mains power of the charging and swapping cabinet is cut off, the battery with higher voltage or more power among the first and second batteries will supply power to the charging and swapping cabinet through the anti-reverse connection circuit. In this way, through this circuit, the battery with the highest power in the charging and swapping cabinet will be used as the power supply to maintain the charging and swapping cabinet, ensuring its normal use. When it is taken out by the customer, the battery with the lowest power will be used as the power supply of the charging and swapping cabinet.
[0021] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
