[0002] In energy storage power supplies, multiple batteries are typically mounted on the same side, with their positive and negative terminals located on the same side. Adjacent batteries are connected in series via busbars, which are usually mounted on a support frame. During the assembly of an energy storage power supply, there is a risk that the busbars may short-circuit the positive and negative terminals of the batteries, potentially causing thermal runaway. Utility Model Content

[0003] This invention provides a connection component and an energy storage device.

[0004] The connection assembly of this application embodiment is used for an energy storage power supply. The connection assembly includes a bracket and an electrical connector. The bracket includes a body and a fixing member disposed on the body. The electrical connector is disposed on the body, wherein the fixing member passes through the electrical connector and fixes the electrical connector to the body to prevent the electrical connector from falling off the body.

[0005] In the embodiments of this application, the connecting component uses a fixing member on the main body to fix the main body and the electrical connector. The fixing member connects the main body and the electrical connector into a whole, which can effectively prevent the electrical connector from moving on the main body. The electrical connector cannot fall off the main body, which is beneficial to the assembly of the connecting component with the battery of the energy storage power supply. Since the position of the electrical connector is fixed, the electrical connector is not likely to short-circuit the battery during the assembly of the energy storage power supply, thus improving the safety of the energy storage power supply assembly.

[0006] In some embodiments, the fastener includes a column and a card, the column connecting the body and the card, the column passing through the electrical connector, and the electrical connector being clamped between the body and the card.

[0007] In the above embodiment, the column passes through the electrical connector, clamping the electrical connector between the card and the bracket body, thereby fixing the fixing member and the electrical connector together. Furthermore, the electrical connector is fixed to the bracket body through the integral connection of the column and the bracket body. The card restricts the movement of the electrical connector relative to the bracket body, making the connection between the electrical connector and the bracket body more stable. Even when the bracket is flipped, the electrical connector and the bracket body will not move relative to each other, ensuring a stable connection and facilitating the automation of the assembly process of the connecting components.

[0008] In some embodiments, the electrical connector includes a plurality of first electrical connectors and a plurality of second electrical connectors, the first electrical connectors being used to electrically connect a plurality of batteries, and at least a portion of the second electrical connectors electrically connecting at least a portion of the batteries and external electrical components, the first electrical connectors and the second electrical connectors being fixed to the body by the fastener.

[0009] In the above embodiment, the fastener fixes the electrical connector, including the first electrical connector and the second electrical connector, to the bracket body. Multiple batteries inside the energy storage power supply are electrically connected through the first electrical connector, and some batteries inside the energy storage power supply and electrical components outside the energy storage power supply are electrically connected through the second connector. In this way, the electrical connector realizes the connection function with the battery.

[0010] In some embodiments, the first electrical connector is disposed on the top surface of the body, and the second electrical connector is bent from the top surface of the body to the side surface of the body.

[0011] In the above embodiment, the first electrical connector is located on the top surface of the bracket body and is used to electrically connect multiple internal batteries; the second electrical connector is located at the edge of the top surface of the bracket body, and the other part is bent to the side of the bracket body at the edge of the body, which is beneficial to connecting the energy storage power supply battery with external electrical components. In addition, the bending setting of the second electrical connector can further restrict the position of the second electrical connector and improve the stability of the second electrical connector.

[0012] In some embodiments, the first electrical connector includes a busbar, a first connecting piece, a second connecting piece, and a mounting piece. The first connecting piece, the second connecting piece, and the mounting piece are all connected to the edge of the busbar. The first connecting piece and the second connecting piece are respectively used to connect the positive and negative terminals of different batteries. The fixing member passes through the mounting piece.

[0013] In the above embodiment, the busbar, the first connecting piece, the second connecting piece, and the mounting piece are a single unit, which together form the first electrical connector. The first connecting piece, the second connecting piece, and the mounting piece are all located at the edge along the length of the busbar. The first connecting piece and the second connecting piece achieve correct battery connection by connecting to the positive and negative terminals of the battery. The mounting piece secures the first electrical connector to the bracket body through a heat-fusion connection with a fixing member. This ensures that the various parts of the first electrical connector do not interfere with each other, thus achieving their respective functions.

[0014] In some embodiments, the body is provided with a plurality of limiting ribs, which are respectively located on both sides of the busbar width direction, and the limiting ribs restrict the displacement of the busbar in the busbar width direction.

[0015] In the above embodiment, the support body is provided with multiple limiting ribs, which are distributed on both sides of the busbar in the width direction. The limiting ribs can restrict the movement of the electrical connector in the length direction of the busbar. Under the action of the limiting ribs, the electrical connector forms a more reliable connection with the support body, so that the electrical connector and the support body can still maintain a correct and effective connection under various vibrations and impacts.

[0016] In some embodiments, the plurality of limiting ribs are staggered and arranged on different sides of the busbar along the length direction of the busbar.

[0017] In the above embodiment, multiple limiting ribs are arranged on different sides of the busbar length direction, which can limit the electrical connector at different positions, prevent the electrical connector from moving in the width direction of the busbar, limit the movement of the electrical connector relative to the width direction of the bracket body, and further ensure the connection stability of the connection assembly.

[0018] In some embodiments, the first connecting piece and the second connecting piece are respectively connected to different sides of the busbar.

[0019] In the above embodiment, the first connecting piece and the second connecting piece are located on different sides of the busbar and are respectively connected to the positive and negative terminals of different batteries to connect the batteries on different sides of the busbar in series.

[0020] In some embodiments, the body is provided with a first through hole and a second through hole spaced apart from the first through hole, the first connecting piece corresponds to the first through hole, and the second connecting piece corresponds to the second through hole.

[0021] In the above embodiment, the first perforation corresponds to the first connecting piece, and the second perforation corresponds to the second connector. The battery is connected to the connecting piece through the perforation, which makes it easy to weld and fix the connecting piece to the battery, thereby improving the stability of the connection between the connecting piece and the battery.

[0022] This application also provides an energy storage power supply, which includes a connection component and a battery according to any of the above embodiments, wherein the bracket is mounted on one end of the battery and the electrical connector is in contact with the battery.

[0023] In the above embodiment, the energy storage power supply connects the battery to external components via a connecting assembly.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the energy storage power supply 300 according to some embodiments of the present invention. The connection component 100 of this application embodiment is used in the energy storage power supply 300. The connection component 100 includes a bracket 10 and an electrical connector 20. The bracket 10 includes a body 11 and a fixing member 12 disposed on the body 11; the electrical connector 20 is disposed on the body 11, wherein the fixing member 12 passes through the electrical connector 20 and fixes the electrical connector 20 to the body 11 to prevent the electrical connector 20 from falling off the body 11.

[0039] In this embodiment, the connecting component 100 uses a fixing member on the main body 11 to fix the main body 11 and the electrical connector 20 together. The fixing member 12 connects the main body 11 and the electrical connector 20 into a whole, which can effectively prevent the electrical connector from moving on the main body. The electrical connector 20 cannot fall off the main body, which is conducive to the assembly of the connecting component 100 with the battery 200 of the energy storage power supply 300. Since the position of the electrical connector 20 is fixed, it is not easy for the electrical connector 20 to short-circuit the battery 200 during the assembly of the energy storage power supply 300, thus improving the safety of the assembly of the energy storage power supply 300.

[0040] Specifically, the bracket 10 is a structural component of the energy storage power supply 300 used to fix, support, and protect the battery 200 and key components. In some embodiments of this application, the bracket 10 is made of insulating material and can be in a honeycomb structure to fix the battery 200. At the same time, the insulating bracket 10 physically isolates the battery 200 from conductive components, avoiding short circuits caused by direct contact between the battery 200 and conductive components.

[0041] The electrical connector 20 is a component that connects multiple batteries 200 together and concentrates the current to an external circuit. In some embodiments of this application, the electrical connector 20 may be made of a highly conductive metal (such as copper or aluminum), and multiple batteries 200 can be connected in series through the electrical connector 20. The current from the batteries 200 is collected together through the electrical connector 20 and delivered to the external circuit.

[0042] The fastener 12 is a mechanical element used to connect, fix or assemble two or more components, ensuring that the connected components maintain a stable relative position and function under stress or motion conditions.

[0043] In some embodiments of this application, the fastener 12 is disposed on the surface of the body 11 and passes through the electrical connector 20. The fastener 12 can be formed by hot melting and fix the body 11 to the electrical connector 20 disposed on the body 11.

[0044] The fastener 12 combines the body 11 and the electrical connector 20 into an integral structure. This connection of the fastener 12 utilizes the adhesive properties of thermoplastic materials in a molten state to achieve a firm connection between the body 11 and the electrical connector 20, effectively preventing the electrical connector 20 from moving relative to the body 11 under the influence of external factors such as vibration and impact, thereby improving the reliability and stability of the connection assembly 100.

[0045] The connecting component 100 is assembled with the battery 200 of the energy storage power supply 300. Since the position of the electrical connector 20 is fixed, the electrical connector 20 is not likely to short-circuit the battery 200 during the assembly of the energy storage power supply 300, which improves the safety of the assembly of the energy storage power supply 300.

[0046] Please refer to Figure 3 , Figure 3 This is a partial cross-sectional view of the connection point of the connecting component 100 in some embodiments of the present invention. In some embodiments, the fastener 12 includes a column 121 and a clip 122. The column 121 connects the body 11 and the clip 122. The column 121 passes through the electrical connector 20, which is sandwiched between the body 11 and the clip 122.

[0047] In the above embodiment, the column 121 passes through the electrical connector 20, clamping the electrical connector 20 between the card 122 and the body 11, thereby fixing the fastener and the electrical connector together. Furthermore, through the integral connection between the column 121 and the body 11, the electrical connector 20 is fixed to the body 11. The card 122 restricts the movement of the electrical connector 20 relative to the body 11, making the connection between the electrical connector 20 and the body 11 more stable. When the bracket 10 is flipped, it still ensures that the electrical connector 20 and the body 11 will not move relative to each other, ensuring a stable connection between the electrical connector 20 and the body 11, which is more conducive to the automated assembly process of the connecting assembly 100.

[0048] Specifically, the cylinder 121 is the part that directly contacts the fastener 12 and the body 11. The bottom of the cylinder 121 contacts the upper surface of the body 11, fixing the fastener 12 to the body 11. In some embodiments of this application, the top of the cylinder 121 is combined with the card 122. The card 122 can be formed from the top of the cylinder 121 by heat fusion. The bottom surface of the heat-fused card 122 can contact the upper surface of the electrical connector 20. The bottom end of the card 122 and the bottom of the cylinder 121 are integral, and the bottom of the cylinder 121 is connected to the body 11.

[0049] During the hot-melting process, after the card 122 melts and cools, it forms a dense and seamless connection with the electrical connector 20, thereby connecting the electrical connector 20 and the body 11 into a whole. This ensures that under normal external forces, there is no relative movement between the electrical connector 20 and the body 11. Even under certain extreme working conditions, such as when the bracket 10 flips up and down, the connection assembly 100 can still be connected normally between the body 11 and the electrical connector 20 during the automated assembly process, which is more conducive to the automation of the assembly process of the connection assembly 100.

[0050] Please refer to again Figure 2 In some embodiments, the electrical connector 20 includes a plurality of first electrical connectors 21 and a plurality of second electrical connectors 22. The first electrical connectors 21 are used to electrically connect a plurality of batteries 200, and at least some of the second electrical connectors 22 are used to electrically connect at least some of the batteries 200 and external electrical components. The first electrical connectors 21 and the second electrical connectors 22 are both fixed to the body 11 by fasteners 12.

[0051] In the above embodiment, the fixing member 12 fixes the electrical connector 20, including the first electrical connector 21 and the second electrical connector 22, to the body 11. The multiple batteries 200 of the energy storage power supply 300 are electrically connected through the first electrical connector 21, and some batteries 200 of the energy storage power supply 300 and external electrical components of the energy storage power supply 300 are electrically connected through the second electrical connector 22. In this way, the electrical connector 20 is connected to the battery 200.

[0052] Specifically, the first electrical connector 21 and the second electrical connector 22 are components of the electrical connector, and the connection between the body 11 and the electrical connector is that the body 11 is connected to the first electrical connector 21 and the second electrical connector 22 respectively. In some embodiments of this application, the first electrical connector 21 connects multiple batteries 200 together, realizing series connection within the batteries 200 and ensuring the correct path and direction of current flow in the batteries 200; the second electrical connector 22 electrically connects some batteries 200 to external electrical components, ensuring the correct connection of the batteries 200, thereby realizing the function of the batteries 200 transmitting current to the outside.

[0053] Please refer to again Figure 2 In some embodiments, the first electrical connector 21 is disposed on the top surface of the body 11, and the second electrical connector 22 is bent from the top surface of the body 11 to the side surface of the body 11.

[0054] In the above embodiment, the first electrical connector 21 is located on the top surface of the body 11 and is used to electrically connect the multiple internal batteries 200; the second electrical connector 22 is partially located at the edge of the top surface of the body 11, and the other part is bent to the side of the body 11 at the edge of the body 11, which facilitates the connection of the batteries 200 of the energy storage power supply 300 to external electrical components. In addition, the bent arrangement of the second electrical connector 22 can further restrict the position of the second electrical connector 22 and improve the stability of the second electrical connector 22.

[0055] Specifically, the top surface of the body 11 is the surface where the fixing member 12 is located. The first electrical connector 21 is located on the top surface of the body 11, ensuring that the first electrical connector 21 is connected to the top surface of the body 11. The first electrical connector 21 connects multiple batteries 200 located inside. The second electrical connector 22 is partially located at the edge of the top surface of the body 11, and the other part is bent to the side of the body 11 through the edge of the body 11, thereby electrically connecting a small number of batteries 200 located inside the bracket 10 to external electrical components, ensuring the correct flow of current and effectively improving the safety of the batteries 200. In addition, the bending setting of the second electrical connector 22 can further restrict the position of the second electrical connector 22, improving the stability of the second electrical connector 22. At the same time, the second electrical connector 22 located on the side of the body 11 also provides structural support for the side of the bracket 10, which helps to improve the overall structural stability of the bracket 10.

[0056] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of the first electrical connector 21 in some embodiments of the present invention. In some embodiments, the first electrical connector 21 includes a busbar 211, a first connecting piece 212, a second connecting piece 213, and a mounting piece 214. The first connecting piece 212, the second connecting piece 213, and the mounting piece 214 are all connected to the edge of the busbar 211. The first connecting piece 212 and the second connecting piece 213 are respectively used to connect the positive and negative terminals of different batteries 200. The fixing member 12 passes through the mounting piece 214.

[0057] In the above embodiment, the first connecting piece 212, the second connecting piece 213, and the mounting piece 214 are all located at the edge of the busbar 211 along its length. The first connecting piece 212 and the second connecting piece 213 achieve the correct connection of the battery 200 by connecting with the positive and negative terminals of the battery 200. The mounting piece 214 achieves the fixation of the first electrical connector 21 on the body 11 by heat-fusion connection with the fixing member 12. This ensures that the various parts of the first electrical connector 21 do not interfere with each other and achieve their respective functions.

[0058] Specifically, in some embodiments of this application, the busbar 211 has a rectangular surface on the first electrical connector 21, and the actual length of the busbar 211 in the longitudinal direction is much greater than its width. The first connecting piece 212 and the second connecting piece 213 are evenly arranged along the edge of the busbar 211 in the longitudinal direction, and are located on both sides of the busbar 211 in the longitudinal direction, respectively, and are connected to the positive and negative electrodes of different batteries 200.

[0059] In some embodiments, the first connector 21 includes one busbar 211, four first connecting pieces 212, four second connecting pieces 213, and two mounting pieces 214. The four first connecting pieces 212 located on one side of the length direction of the busbar 211 are connected to the positive terminals of the four batteries 200, and the four second connecting pieces 213 located on the other side of the length direction of the busbar 211 are connected to the negative terminals of the four batteries 200. Thus, the first electrical connector connects the four batteries 200 in parallel, and then connects them in series with adjacent electrical connectors 20 to achieve a correct connection of multiple batteries 200. In this way, the batteries 200 inside the bracket 10 form a safe current path.

[0060] The first electrical connector 21 includes a mounting plate 214 integrated with the busbar 211. The mounting plate 214 is the part that contacts the first electrical connector 21 and the fixing member 12. The fixing member 12 passes through the mounting plate 214. The fixing member 12 forms a card 122 at the top of the column 121 by heat fusion. The various parts of the first electrical connector 21 do not interfere with each other and realize their respective functions.

[0061] When the bottom of the card 122 contacts the top of the mounting piece 214, the busbar 211, which is integrally connected to the mounting piece 214, is fixed to the fixing member 12. At this time, the first electrical connector 21 is fixed to the fixing member 12 as a whole. The first electrical connector 21 and the body 11 cannot move relative to each other, and the first electrical connector 21 will not move or fall off the body 11.

[0062] Please refer to Figure 5 , Figure 5This is a schematic diagram of the bracket 10 according to some embodiments of the present invention. In some embodiments, the body 11 is provided with a plurality of limiting ribs 111, which are respectively located on both sides of the busbar 211 in the width direction. The limiting ribs 111 restrict the displacement of the busbar 211 in the width direction of the busbar 211.

[0063] In the above embodiment, the body 11 is provided with a plurality of limiting ribs 111, which are distributed in the width direction of the busbar 211. The limiting ribs 111 can restrict the movement of the electrical connector 20 in the length direction of the busbar 211. Under the action of the limiting ribs 111, the electrical connector 20 forms a more reliable connection with the body 11, so that the electrical connector 20 and the body 11 can still maintain a correct and effective connection under various vibrations and impacts.

[0064] Specifically, the limiting rib 111 is a raised reinforcing rib or edge structure in a mechanical structure. It is usually designed on the surface or edge of a part to limit the relative movement between components, ensure accurate positioning during assembly, or prevent misalignment or loosening.

[0065] In some embodiments of this application, the limiting rib 111 is a protrusion located on the surface of the body 11. Its structure is a cuboid protrusion, and the top of the protrusion away from the surface of the body 11 is provided with rounded corners, which can effectively concentrate wall stress and facilitate the assembly guidance of the electrical connector 20.

[0066] The limiting rib 111 is located on one side of the busbar 211 in the width direction. On the surface of the body 11, the first electrical connector 21 and the second electrical connector 22 on the electrical connector 20 form a notch edge with the busbar 211, respectively, to ensure that the electrical connector 20 cannot move relative to the length direction of the busbar 211 on the surface of the body 11 after it is connected to the body 11.

[0067] Please refer to Figure 4 and Figure 5 In some embodiments, multiple limiting ribs 111 are staggered along the length of the busbar 211 on different sides of the busbar 211.

[0068] In the above embodiment, multiple limiting ribs 111 are disposed on different sides of the busbar 211 along its length, which can limit the electrical connector at different positions, prevent the electrical connector 20 from moving in the width direction of the busbar 211, limit the movement of the electrical connector 20 relative to the width direction of the body 11, and further ensure the connection stability of the connection assembly 100.

[0069] Specifically, in some embodiments of this application, a plurality of protruding limiting ribs 111 on the body 11 are staggered on different sides of the busbar 211 along its length. When the limiting ribs 111 are only provided on the same side of the busbar 211 along its length, the limiting ribs 111 can restrict the movement of the electrical connector 20 in the length direction of the busbar 211; when the limiting ribs 111 are provided on both sides of the busbar 211 along its length, the limiting ribs 111 can restrict the movement of the electrical connector 20 in both the length and width directions of the busbar 211. Thus, by providing the limiting ribs 111 on different sides of the busbar 211 along its length, the movement of the electrical connector 20 in both the length and width directions of the busbar 211 can be effectively restricted, ensuring the relative stillness of the electrical connector 20 and the body 11.

[0070] Please refer to again Figure 4 In some embodiments, the first connecting piece 212 and the second connecting piece 213 are respectively connected to different sides of the busbar 211.

[0071] In the above embodiment, the first connecting piece 212 and the second connecting piece 213 are located on different sides of the busbar 211 and are respectively connected to the positive and negative terminals of different batteries 200, so as to connect the batteries 200 on different sides of the busbar 211 in series.

[0072] Specifically, in some embodiments of this application, the first connecting piece 212 is the portion of the first electrical connector 21 that is connected to the busbar 211 and protrudes towards the edge of the busbar 211 in the width direction. The second connecting piece 213 is another portion of the first electrical connector 21 that is connected to the busbar 211 and protrudes towards the edge of the busbar 211 in the other direction in the width direction. The first connecting piece 212 and the second connecting piece 213 are the first positions where the current from the battery 200 flows to the electrical connector 20. The first connecting piece 212 and the second connecting piece 213 are respectively connected to the positive and negative terminals of different batteries 200, connecting the batteries 200 on different sides of the busbar 211 in series. This ensures the correct path and direction of the current from the batteries 200 on different sides of the busbar 211, guaranteeing the safety and functionality of the batteries 200.

[0073] Please refer to again Figure 5 In some embodiments, the body 11 is provided with a first through hole 112 and a second through hole 113 spaced apart from the first through hole 112, the first connecting piece 212 corresponds to the first through hole 112, and the second connecting piece 213 corresponds to the second through hole 113.

[0074] In the above embodiment, the first through hole 112 and the second through hole 113 are located on different sides of the busbar 211. The first through hole 112 corresponds to the first connecting piece 212, and the second through hole 113 corresponds to the second connector. The battery 200 is connected to the connecting piece through the through hole, which makes it easy to weld and fix the connecting piece to the battery 200, thereby improving the stability of the connection between the electrical connecting piece and the battery 200.

[0075] Specifically, in some embodiments of this application, the first connecting piece 212 and the second connecting piece 213 can be connected to the battery 200 through perforations on the bracket body 11. The perforations on the bracket body 11 correspond one-to-one with the connecting pieces; the first perforation 112 connects to the first connecting piece 212, and the second perforation 113 connects to the second connecting piece 213, ensuring that each connecting piece can be connected to the battery 200. In this way, the connecting pieces can be welded and fixed to the battery 200 through the perforations, improving the stability of the connection between the connecting pieces and the battery 200, thereby enabling the electrical connector 20 to be accurately connected to the positive and negative terminals of different batteries 200, ensuring the safety of the battery 200.

[0076] Please see Figure 1 In some embodiments, the energy storage power supply 300 of this application includes a connection component 100 and a battery 200 as described in any of the above embodiments, with a bracket 10 installed at one end of the battery 200 and an electrical connector 20 in contact with the battery 200.

[0077] In the above embodiment, the energy storage power supply 300 connects the battery 200 to external components via the connecting assembly 100. The electrical connector 20, through contact with the battery 200, achieves series connection of the current within the battery 200, correctly guiding the current and preventing short circuits within the battery 200, further reducing the risk of thermal runaway of the energy storage power supply 300. The bracket 10 is installed at one end of the battery 200, providing support and preventing displacement of the battery 200 due to external vibration or impact.

[0078] Specifically, the energy storage power supply 300 is a device or system capable of storing electrical energy and releasing it for use when needed. In some embodiments of this application, the battery 200 is the energy output source of the energy storage power supply 300, and the electrical connector 20 is located on the surface of the bracket 10 and is connected to the battery 200 through a perforation on the bracket 10, thereby connecting the positive and negative terminals of different batteries 200 inside the bracket 10 to form a series circuit, thus constituting a complete energy output path.

[0079] The bracket 10 is installed at one end of the battery 200. The electrical connector 20 only needs to be assembled with the bracket 10 on the upper surface of the bracket 10, which effectively reduces the volume of the energy storage power supply 300 and is conducive to achieving lightweighting and improving production efficiency.

[0080] In one embodiment, the energy storage power supply 300 requires an assembly process to assemble the electrical connector 20, the bracket 10, and the battery 200 into a whole. The assembly process of the energy storage power supply 300 is as follows:

[0081] 1. Install the electrical connector 20 onto the bracket 10 and make the fixing member 12 pass through the electrical connector 20. Use the limiting function of the limiting rib 111 to keep the electrical connector 20 in the predetermined position.

[0082] 2. The electrical connector 20 is fixed to the body 11 by the fixing member 12. Specifically, the card 122 on the top of the fixing member 12 can be formed by hot melting. During the hot melting process, the card 122 and the electrical connector 20 form a dense bond. The electrical connector 20 and the bracket 10 are fixed together to form the connecting assembly 100.

[0083] 3. Install the connecting assembly 100 onto one end of the multiple batteries 200, so that the electrical connectors 20 correspond to the through holes on the body 11 through the connecting pieces of the first electrical connector 21 and the second electrical connector 22 respectively.

[0084] 4. Weld the connecting pieces of the first electrical connector 21 and the second electrical connector 22 to the positive and negative terminals of the corresponding battery 200. At this time, the connecting assembly 100 and the battery 200 are connected to form at least part of the energy storage power supply 300.
