detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the utility model and implement it, but the examples given are not intended to limit the utility model.

Please refer to Figures 2 to 4, Figure 2 is a schematic diagram of the appearance of a voltage dynamic self-balancing energy storage device 20 according to an embodiment of the present invention, and Figure 3 is a combination of multiple voltage dynamic self-balancing energy storage devices 20 according to an embodiment of the present utility model Schematic diagram, FIG. 4 is a schematic diagram of the internal structure of the parallel connection of voltage dynamic self-balancing energy storage devices 20 according to the embodiment of the present utility model. The voltage dynamic self-balancing energy storage device 20 includes a housing 22 , an input terminal group 24 with a first clamping male terminal 38 , an output terminal group 26 with a second clamping female terminal 40 , a protection circuit board 28 and a conduction mechanism 30 . The voltage dynamic self-balancing energy storage device 20 may be a battery box. The housing 22 can be any form of container, not limited to hard containers or soft packaging materials; the housing 22 can be removed directly, and only the conduction mechanism 30 is arranged between the input terminal group 24 and the output terminal group 26 , and communicate with the protection circuit board 28 and the energy storage unit 32 . At least one energy storage unit 32 is housed in the casing 22, which means that the voltage dynamic self-balancing energy storage device 20 may be a single-cell (one energy storage unit 32) battery, or a plurality of battery cells (multiple battery cells) connected in series/parallel energy unit 32) of the battery pack. The first clamping male terminal 38 combined with the input terminal group 24 and the second clamping female terminal 40 combined with the output terminal group 26 are generally arranged on two opposite sides of the housing 22, and the Lego building blocks are forced to be positioned by the housing engagement mechanism. The combination method is used to connect the second clamping female terminal 40 corresponding to the output terminal group 26 and the first clamping male terminal 38 corresponding to the input terminal group 24 of the adjacent voltage dynamic self-balancing energy storage device 20 . Of course, the present invention can also arrange the second clamping female terminal 40 in the input terminal group 24 and the first clamping male terminal 38 in the output terminal group 26 , and its application is not limited thereto. A protective circuit board 28 is provided within the housing 22 . One end of the protection circuit board 28 is electrically connected to the conduction mechanism 30 through the first transmission line 34 , and the other end of the protection circuit board 28 is electrically connected to the energy storage unit 32 through the second transmission line 36 . Two ends of the conduction mechanism 30 are respectively connected to the input terminal group 24 having the first clamping male terminal 38 and the output terminal group 26 having the second clamping female terminal 40 . The first clamping male terminal 38 of the input terminal group 24 and the second clamping female terminal 40 of the output terminal group 26 are connected to the protection circuit board 28 by the first transmission line 34 through the conduction mechanism 30, and are controlled by the voltage of the protection circuit board 28 function and is electrically connected to the energy storage unit 32 . Among them, the input terminal group 24 accommodates the first clamping male terminal 38 inside and forms a concave structure relative to the housing 22, so as to prevent the user from accidentally touching the first clamping male terminal 38 and getting an electric shock, and at the same time, it can be used to accommodate another voltage dynamic The output terminal group of the self-balancing energy storage device is combined with the second clamping female terminal built in the output terminal group, so that adjacent voltage dynamic self-balancing energy storage devices can be combined in parallel. The output terminal set 26 protrudes relatively from the housing 22 for receiving the second clamping female terminal 40 .

The combination of the first clamping male terminal 38 of the input terminal group 24 can be divided into a plurality of input positive terminals 241 and input negative terminals 242, and the combination of the second clamping female terminal 40 of the output terminal group 26 can be divided into a plurality of output positive terminals. terminal 261 and output negative terminal 262 . The conduction mechanism 30 is bridged between the input terminal group 24 and the output terminal group 26, and the number is not limited to that shown in the figure; for example, the voltage dynamic self-balancing energy storage device 20 may have six or eight conduction mechanisms 30 or even more, Used to shunt to reduce temperature rise. The combined numbers of positive/negative terminals of the first clamping male terminal 38 of the input terminal set 24 and the second clamping female terminal 40 of the output terminal set 26 also change correspondingly with the number of the conduction mechanisms 30 . When the voltage dynamic self-balancing energy storage device 20 is charging or discharging, the first clamping male terminal 38 of the input terminal group 24 first receives the power signal from the external power device, and then the power signal preferably passes through the conduction mechanism 30 The second clamping female terminal 40 which is directly and simultaneously conducted to the output terminal set 26 and/or electrically connected to the energy storage unit 32 via the voltage control of the protection circuit board 28 , instead of only being transmitted to the energy storage unit 32 . In this way, when multiple voltage dynamic self-balancing energy storage devices 20 are combined, for example, multiple voltage dynamic self-balancing energy storage devices 20 are connected in series or in parallel, and the voltage dynamic self-balancing energy storage devices 20 are charged from an external power device. The power signal will not only be preferentially charged into the voltage dynamic self-balancing energy storage device 20 with the lowest voltage among the multiple voltage dynamic self-balancing energy storage devices 20, but the direct current guiding channel established by the conduction mechanism 30 is used to allow high The current in the voltage dynamic self-balancing energy storage device 20 of voltage actively flows to the voltage dynamic self-balancing energy storage device 20 with low voltage through the conduction mechanism 30, a dynamic self-balancing platform of voltage and electricity; that is, the conduction mechanism 30 The high voltage of the high voltage respectively flows to all the dynamic self-balancing energy storage devices 20 with voltages lower than the voltage of the conduction mechanism 30 at the same time. The voltage difference between the dynamic self-balancing energy storage devices 20 of different voltages can also be used to induce a dynamic self-balancing current flow through the conduction mechanism 30, which is a dynamic self-balancing platform of voltage and electricity; and vice versa during discharge. At this time, the protection circuit board 28 in the energy storage device 20 is designed to have the functions of charging cutoff and discharge current limiting minimum cutoff, so as to protect the energy storage device 20 through voltage and current control. If the protection circuit board 28 detects that the voltage of the energy storage unit 32 is lower than the voltage of the conduction mechanism 30, the energy storage unit 32 is charged within 0.5C until the set full charge cut-off point is reached. When discharging, if the protection circuit board 28 detects that the voltage of the energy storage unit 32 is higher than the voltage of the conduction mechanism 30, the current is limited within 2C and the higher voltage current of the energy storage unit 32 flows into the conduction mechanism through discharge. 30. Discharge all the way to the set discharge cut-off point. The relevant parameter setting is not limited to this, and depends on actual needs.

The voltage dynamic self-balancing energy storage device 20 of the present utility model utilizes the physical characteristics of the conduction mechanism 30 and adopts high-conductivity materials to guide the flow of voltage and current to achieve the dynamic self-balancing function of voltage and electricity. For example, the conduction mechanism 30 can be Silver-plated metal materials, but the practical application is not limited thereto. In other words, since the conducting member 31 is provided between the first clamping male terminal 38 of the input terminal group 24 and the second clamping female terminal 40 of the output terminal group 26, the conducting member 31 is used to guide the current directly to the input A current guiding channel is established between the first clamping male terminal 38 of the terminal group 24 and the second clamping female terminal 40 of the output terminal group 26, using the physical characteristics of dynamic self-balancing of voltage and electricity to automatically flow voltage and current to balance the connected Multiple energy storage devices 20, instead of just charging or discharging the energy storage device with the lowest voltage or worst quality first. When multiple voltage dynamic self-balancing energy storage devices 20 are connected to form an energy storage combination, the multiple voltage dynamic self-balancing energy storage devices 20 will dynamically self-balance to the total voltage of the conduction mechanism 30 according to their individual voltages and energy storage combinations The difference between them receives or overflows the adapted power signal respectively, which means that the conduction mechanism 30 of each voltage dynamic self-balancing energy storage device 20 will be based on the parameters of the power signal of other voltage dynamic self-balancing energy storage devices (such as its voltage and current values) ), the dynamic self-balancing transmits power signals with corresponding parameters to other energy storage devices 20, so that the current and voltage between each voltage dynamic self-balancing energy storage device 20 in the energy storage combination can depend on the conduction mechanism according to physical characteristics 30 generates dynamic flow until the voltage balance between all energy storage devices 20 is consistent within a specific range to reach a steady state. This revolutionary design improvement allows the energy storage device 20 to have the advantage of greatly increasing the reliable service life; at the same time, because The voltage can be easily increased or the power can be expanded, so that the energy storage device 20 can be expanded and used in any DC energy storage occasions.

Moreover, the direct current guiding channel of the conduction mechanism 30 between the first clamping male terminal 38 of the input terminal group 24 and the second clamping female terminal 40 of the output terminal group 26 can allow the energy storage to be combined in a short time. The voltages and currents of all voltage dynamic self-balancing energy storage devices 20 generate physical dynamic self-balancing flows, which can not only effectively achieve the voltage balance and stability of multiple voltage dynamic self-balancing energy storage devices 20, but also avoid voltage dynamic self-balancing. The components of the energy storage device 20 heat up excessively, so there is no need to set up an additional expensive water-cooled or air-cooled cooling system. However, the conduction mechanism 30 should still preferably be made of materials with high heat resistance, high electrical conductivity and high power characteristics to improve the safety of the energy storage combination; for example, when the energy storage combination is dynamically self-balanced by more voltages When the devices 20 are combined in series or in parallel, the conduction mechanism 30 of each voltage dynamic self-balancing energy storage device 20 must have the characteristics of high heat resistance, high conductivity and high power, so as to safely carry large currents. The number, length, width and thickness of the conduction mechanism 30 are based on the preset power required by the electric energy, the number of built-in energy storage units 32 of each voltage dynamic self-balancing energy storage device 20, and the voltage dynamic self-balancing storage included in the energy storage combination. The number of energy devices 20 and the maximum current set by the protection circuit board 28 to control charging and/or discharging; for safety reasons, the specification of the discharging port is generally not more than 200 amperes, but may not be limited thereto.

The voltage dynamic self-balancing energy storage device 20 of the present utility model has a specific storage capacity according to the quantity and specifications of its energy storage units 32, and is used to supply power to any form of electric device; if the electric device needs a larger power source, then Multiple voltage dynamic self-balancing energy storage devices 20 are combined to form an energy storage combination with higher storage capacity. Therefore, each voltage dynamic self-balancing energy storage device 20 can accommodate a plurality of energy storage units 32, but the internal impedance coefficient of any energy storage unit 32 of the plurality of energy storage units 32 is preferably within a specific range; In addition to the premise that multiple energy storage units 32 in the same voltage dynamic self-balancing energy storage device 20 have the same impedance and other specifications within the range, the impedance of the energy storage units 32 in different voltage dynamic self-balancing energy storage devices 20 The specifications should also be substantially the same within a specific range, so as to ensure the safety and stability of the energy storage combination during charging and discharging.

In particular, the voltage dynamic self-balancing energy storage device 20 may optionally include a first transmission line 34 connecting the conduction mechanism 30 and the protection circuit board 28 , and a second transmission line connecting the protection circuit board 28 and the energy storage unit 32 36. The first transmission line 34 and the second transmission line 36 are independent of each other. If the voltage dynamic self-balancing energy storage device 20 is a lithium battery type, the maximum charging current that must be activated by the protection circuit board 28 is limited to no more than 0.5C until the set full charging point ends. The discharge current is limited within 2C, and it is cut off until the set discharge cut-off point. The relevant parameter setting is not limited to this, and depends on actual needs.

The conduction module 56 can be used as a parallel connection line between the voltage dynamic self-balancing energy storage devices 20 . The first clamping male terminal 38 can be plate-shaped or cylindrical or other shapes, and the second clamping female terminal 40 is a kind of Y-shaped chuck, and its clamping part is plate-shaped or column-shaped corresponding to the first clamping male terminal 38 Or other shape clamping structures. The first clamping male terminal 38 of each voltage dynamic self-balancing energy storage device 20 can be inserted into the second clamping female terminal 40 of another voltage dynamic self-balancing energy storage device 20 to establish a connection between the voltage dynamic self-balancing energy storage device 20 the current transmission channel between them. Since a plurality of voltage dynamic self-balancing energy storage devices 20 can be connected in series or in parallel to form an energy storage combination, the first clamping male terminal 38 and the second clamping terminal 40 preferably need to increase their thickness and clamping area, taking into account High electrical conductivity and high heat dissipation efficiency can effectively reduce the operating temperature when charging and discharging the energy storage combination, and enhance the convenience and safety of the product.
