Description

Technical Field

[0001] This utility model relates to the field of new energy batteries, and more specifically, to a battery system for forklifts. Background Technology

[0002] The battery system provides power to the forklift, enabling it to operate smoothly.

[0003] Existing battery systems include battery modules and electrical components. The battery module includes end plates and one or two steel strips that are set on both sides of the battery pack and surround the steel plate, and the end plates and battery pack are fixed by the steel strips.

[0004] However, during the use of the battery system, the battery pack will expand due to repeated use. The expansion will generate force, and the stress point will appear at the corresponding position of the steel strip. This will result in uneven stress and generate great local extrusion pressure on the battery pack and steel strip, which can easily cause damage to the battery pack and steel strip. Utility Model Content

[0005] This invention provides a new technical solution for a battery system for forklifts, which can at least solve the problems of easy damage and low safety of battery packs in the prior art.

[0006] According to this utility model, a battery system for forklifts is provided. The battery system includes a battery module, a housing for the battery module, and electrical components for connecting the battery module. The battery module includes:

[0007] Battery pack;

[0008] Two first side plates are respectively disposed at the left and right ends of the battery pack;

[0009] Two second side plates are respectively disposed at the front and rear ends of the battery pack. The two second side plates and the two first side plates can be enclosed to form a frame to house the battery pack.

[0010] Fasteners that connect adjacent first side plates and second side plates.

[0011] The housing has a first accommodating space and a second accommodating space along a first direction. The first accommodating space includes a first battery compartment. The second accommodating space has a second battery compartment and an electrical compartment along a second direction. The first direction is the height direction, and the second direction is the length direction. The electrical components are disposed in the electrical compartment and are electrically connected to the battery module.

[0012] Furthermore, the bottom of the first side plate has a first folded edge that bends inward, and the bottom of the battery pack is supported by the first folded edge;

[0013] The edges of the second side panel are all bent outward to form a second folded edge.

[0014] Furthermore, both the front and rear ends of the first side plate have extended edges that overlap with the second folded edge, and the fastener connects the extended edges and the second folded edge.

[0015] Furthermore, the first side plate has a first convex bulge protruding outwards, and the second side plate has a second convex bulge protruding outwards.

[0016] Furthermore, the electrical components are disposed on the inner wall of the electrical compartment.

[0017] Furthermore, the battery module comprises multiple modules arranged vertically, and the battery system further includes:

[0018] A partition is disposed inside the housing and is located at the junction of the first accommodating space and the second accommodating space in the first direction; the partition serves as the bottom surface of the second battery compartment and is used to support the battery module inside the second battery compartment.

[0019] Furthermore, the housing has a first opening in a third direction, wherein the third direction is the width direction, and the battery system includes:

[0020] A first sealing plate is detachably disposed at the first opening to close the first opening.

[0021] Furthermore, the housing has a second opening in the first direction, and the battery system further includes:

[0022] A second sealing plate is detachably disposed at the second opening to close the second opening.

[0023] Furthermore, the electrical compartment is connected to the upper part of the battery compartment, so that the housing forms an inverted "L" shape. The battery pack is a sodium-ion battery cell or a lithium-ion battery cell. The battery system also includes:

[0024] A receiving slot with an opening at the top, the receiving slot accommodating the housing, the lower part of the battery compartment and the lower part of the electrical compartment being embedded in the receiving slot;

[0025] A counterweight is disposed at the bottom of the receiving slot and abuts against the housing. The counterweight is disposed opposite to the battery compartment in the second direction and opposite to the electrical compartment in the first direction.

[0026] Furthermore, the counterweight is detachably connected to the receiving groove.

[0027] According to the battery system for forklifts of this utility model, two opposing first side plates are respectively provided at the left and right ends of the battery pack, and two opposing second side plates are respectively provided at the front and rear ends of the battery pack. The first and second side plates are connected by fasteners, so that the two first side plates and two second side plates form a frame surrounding the battery pack. Therefore, the two first side plates and two second side plates can evenly bear the expansion force of the battery pack, thereby buffering the expansion force and better protecting and securing the battery pack. This avoids the problem of damage to the battery pack and steel strip caused by conventional end plates and steel strips when the battery pack is subjected to expansion forces.

[0028] The battery modules are housed in the battery compartment within the enclosure, while the electrical components are housed in an electrical compartment located before or behind the battery compartment. The electrical components are isolated from the battery modules, rather than stacked together, which reduces the impact of the battery modules on the electrical components (such as compression, collisions, and friction between the battery modules and electrical components), thus increasing safety. Furthermore, placing the electrical components before or behind the battery modules, rather than on top of them, reduces the vertical space required for the battery system.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0050] The battery system for a forklift according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0051] like Figures 1 to 8 As shown, the battery system for a forklift according to an embodiment of the present invention includes a battery module 100, a housing 210 for housing the battery module 100, and an electrical component 300 for connecting the battery module 100.

[0052] First, the battery module 100 is described. The battery module 100 includes a battery pack, two first side plates 110, two second side plates 120, and fasteners 130. The battery pack includes multiple individual battery cells. The two first side plates 110 are respectively disposed at the left and right ends of the battery pack. The two second side plates 120 are respectively disposed at the front and rear ends of the battery pack. The two second side plates 120 and the two first side plates 110 can be joined to form a frame for housing the battery pack. Fasteners 130 connect adjacent first side plates 110 and second side plates 120. Fasteners 130 can be rivets, bolts / nuts, clamps, etc.

[0053] like Figures 4 to 6 As shown, two opposing first side plates 110 are respectively provided at the left and right ends of the battery pack, and two opposing second side plates 120 are respectively provided at the front and rear ends of the battery pack. The first side plates 110 and the second side plates 120 are connected by fasteners 130, so that the two first side plates 110 and the two second side plates 120 form a frame surrounding the battery pack. Therefore, the two first side plates 110 and the two second side plates 120 can evenly bear the expansion force of the battery pack, thereby buffering the expansion force and better protecting and securing the battery pack. This avoids the problem of damage to the battery pack and steel strip caused by conventional end plates and steel strips when the battery pack is subjected to the expansion force.

[0054] The housing has a first accommodating space and a second accommodating space along a first direction. The first accommodating space includes a first battery compartment. The second accommodating space has a second battery compartment and an electrical compartment along a second direction. The first direction is the height direction and the second direction is the length direction. The electrical components are disposed in the electrical compartment 213 and are electrically connected to the battery module 100.

[0055] like Figure 1 As shown, the up-down direction is the first direction, the front-back direction is the second direction, and the left-right direction is the third direction. See the attached diagram for further details. Figure 1 .

[0056] like Figures 1 to 3As shown, the battery module 100 is disposed in the battery compartment 214 in the height direction within the housing 210, and the electrical component 300 is disposed in the electrical compartment 213 located in front of or behind the battery compartment 214 within the housing 210. The electrical component 300 is relatively isolated from the battery module 100, rather than stacked with it, which reduces the impact of the battery module 100 on the electrical component 300 (such as squeezing, collision, and friction between the battery module 100 and the electrical component 300), increasing safety. Furthermore, the electrical component 300 is disposed in front of or behind the battery module 100, rather than on top of it, which reduces the vertical space required for the battery system. The electrical component 300 is connected to the battery module 100 via wires.

[0057] In some embodiments of this utility model, the bottom of the first side plate 110 is formed with a first folded edge 111 that bends inward, and the bottom of the battery pack is supported by the first folded edge 111.

[0058] like Figure 5 As shown, the bottom edges of the two first side plates 110 are bent inward (i.e., the bottom edge of the first side plate 110 on the left side bends to the right, and the bottom edge of the first side plate 110 on the right side bends to the left) to form the first folded edge 111, which forms a bottom support that can support the bottom of the battery pack, thus enabling it to better support the battery pack. Moreover, this structure is relatively simple.

[0059] Furthermore, the edges of the second side plate 120 are all bent outward to form a second folded edge 121.

[0060] like Figure 4 and Figure 5 As shown, the edges of both second side plates 120 are bent outwards (i.e., the four edges of the second side plate 120 at the front end are bent forward, and the four edges of the second side plate 120 at the rear end are bent backwards) to form a second folded edge 121. The second side plate 120 can be easily connected to the first side plate 110 through the second folded edge 121.

[0061] Furthermore, both the front and rear ends of the first side plate 110 are formed with extended edges that overlap with the second folded edge 121, and the fastener 130 connects the extended edges and the second folded edge 121.

[0062] like Figure 5 As shown, the extended edge and the second folded edge 121 of the first side plate 110 have an L-shaped overlap (both the side and bottom edges of the first side plate 110 are extended). The fastener 130 connects the extended edge and the second folded edge 121, thereby making the adjacent first side plate 110 and second side plate 120 firmly connected and avoiding interference of the fastener 130 with the battery pack.

[0063] Furthermore, a first mounting hole 113 is formed on the extended edge, and a second mounting hole 123 corresponding to the first mounting hole 113 is formed on the second folded edge 121. The fastener 130 includes a bolt and a nut that cooperate with each other. The bolt passes through the first mounting hole 113 and the second mounting hole 123 and is threadedly connected to the nut.

[0064] like Figure 4 and Figure 5 As shown, the first mounting hole 113 of the extended side is aligned with the second mounting hole 123 of the second folded edge 121. The bolt passes through the first mounting hole 113 and the second mounting hole 123, and the nut locks the end of the bolt, thereby making the extended side of the first side plate 110 and the second folded edge 121 of the second side plate 121 tightly connected, and thus making the first side plate 110 and the second side plate 120 tightly connected.

[0065] In some embodiments of this invention, the battery module 100 further includes a separator. The separator is disposed on the side of the battery pack, and both the first side plate 110 and the second side plate 120 are connected to the battery pack through the separator. The separator can be a PI film (polyimide film) or similar material.

[0066] The separator membrane provides a buffer between the first side plate 110 and the second side plate 120, better protecting the battery pack. Furthermore, it offers good electrical insulation, reducing external interference to the battery pack.

[0067] In some embodiments of the present invention, the first side plate 110 is formed with a first protrusion 112 protruding outward, and the second side plate 120 is formed with a second protrusion 122 protruding outward.

[0068] like Figure 4 and Figure 5 As shown, the first side plate 110 has a "well"-shaped first protrusion 112, and the second side plate 120 has a "well"-shaped second protrusion 122. The first protrusion 112 and the second protrusion 122 can increase the strength of the first side plate 110 and the second side plate 120. Moreover, when an external object impacts the first side plate 110 and the second side plate 120, the first protrusion 112 and the second protrusion 122 can provide cushioning. Even if the second protrusion 122 is deformed or damaged, the battery pack can still remain intact, thereby better protecting the battery pack.

[0069] In some embodiments of this utility model, multiple individual battery cells are arranged in a front-to-back configuration. The battery module 100 further includes a first electrode plate 161, a second electrode plate 162, a third electrode plate 163, a positive terminal connector 181, and a negative terminal connector 182. The first electrode plate 161 is connected to the positive terminal of the individual battery cell located at the rear end. The second electrode plate 162 connects the positive and negative terminals of adjacent individual battery cells, thereby connecting the individual battery cells in series. The third electrode plate 163 is connected to the negative terminal of the individual battery cell located at the front end. The positive terminal connector 181 is connected to the first electrode plate 161. The negative terminal connector 182 is connected to the third electrode plate 163.

[0070] like Figure 6 As shown, four individual battery cells are arranged in front of and behind each other. The four individual battery cells are connected in series through the second tab 162. The positive terminal is led out through the first tab 161 and the positive terminal connector 181, and the negative terminal is led out through the third tab 163 and the negative terminal connector 182. This makes it convenient for the battery module 100 to supply power to the outside world and for the outside world to charge the battery module 100.

[0071] Furthermore, the battery module 100 also includes an FPC acquisition harness. The FPC acquisition harness includes multiple connecting wires 172 and a connector 171. The first ends of the multiple connecting wires 172 are respectively connected to a first contact plate 161, a second contact plate 162, and a third contact plate 163. The connector 171 connects to the second ends of the multiple connecting wires 172. Figure 6 As shown, multiple connecting lines 172 are respectively connected to the first plate 161, the third plate 163 and the second plate 162, so as to be connected to each battery pack and obtain the signals (voltage, current, temperature, etc.) of each battery pack. The multiple connecting lines 172 are connected through the connector 171, which can be conveniently connected to the battery management system (BMS).

[0072] Optionally, the first end of the connecting wire can be connected to the first plate 231, the third plate 233, or the second plate 232 via a nickel plate. An NTC (thermistor) is provided on the nickel plate for temperature acquisition.

[0073] Furthermore, the battery module 100 also includes a baffle 150 and a top plate 140. The baffle 150 covers the top of the battery pack, the first plate 161, the third plate 163, and the second plate 162, and has cutouts formed at the positions of the first plate 161, the third plate 163, and the second plate 162. Connecting lines 172 are disposed on the baffle 150. The top plate 140 covers the baffle 150.

[0074] like Figure 6As shown, the baffle 150 has perforations at the positions of the first pad 161, the third pad 163, and the second pad 162, which can avoid the connection point of the connecting line 172 connecting the first pad 161, the third pad 163, and the second pad 162, thus preventing interference. The baffle 150 and the top plate 140 can cover the connecting line 172, thereby better protecting the connecting line 172.

[0075] In some embodiments of this utility model, the electrical component 300 is disposed on the inner wall of the electrical compartment 213.

[0076] like Figure 3 As shown, the electrical component 300 is suspended on the inner wall of the electrical compartment 213 of the housing 210 and fixed in place, ensuring that the electrical component 300 does not occupy too much space and that the fixing of the electrical component 300 is more stable.

[0077] In some embodiments of this utility model, the battery module 100 includes multiple battery modules 100 arranged vertically, and the battery system also includes a separator. The separator 215 is disposed inside the housing 210, and the separator 215 is located at the junction of the first accommodating space and the second accommodating space in the first direction. The separator 215 serves as the bottom surface of the second battery compartment and is used to support the battery modules 100 inside the second battery compartment.

[0078] like Figure 3 As shown, the partition 215 is installed inside the housing 210 at the junction of the first accommodating space and the second accommodating space. It supports the battery module 100 in the second battery compartment, reduces the mutual influence (squeezing, collision, friction, etc.) between the battery module 100 in the first battery compartment and the battery module 100 in the second battery compartment, and further increases safety.

[0079] In some embodiments of this utility model, a first opening 212 is formed in a third direction, which is the width direction. The battery system includes a first sealing plate 220. The first sealing plate 220 is detachably disposed at the first opening 212 to close the first opening 212.

[0080] like Figure 1 and Figure 2 As shown, the housing 210 has a first opening 212 on its left side. The first sealing plate 220 closes the first opening 212 with fasteners 130 (bolts / nuts), which facilitates the assembly and disassembly of the battery module 100 and the electrical components 300.

[0081] Furthermore, the housing 210 is provided with a second opening 211 in the first direction, and the battery system also includes a second sealing plate 230. The second sealing plate 230 is detachably disposed at the second opening 211 to close the second opening 211.

[0082] like Figure 1 and Figure 2 As shown, a second opening 211 is formed on the top of the housing 210, and a second sealing plate 230 closes the second opening 211. The second opening 211 facilitates the maintenance of the battery system.

[0083] In some embodiments of this utility model, the electrical compartment 213 is connected to the upper part of the battery compartment 214, so that the housing 210 forms an inverted "L" shape, and the individual battery cells are sodium-ion cells or lithium-ion cells. The battery system also includes a receiving slot 500 and a counterweight 400. The receiving slot 500 has an opening at the top and accommodates the housing 210. The lower parts of the battery compartment 214 and the lower parts of the electrical compartment 213 are embedded in the receiving slot 500. The counterweight 400 is disposed at the bottom of the receiving slot 500 and abuts against the housing 210. The counterweight 400 is disposed opposite to the battery compartment 214 in a second direction and opposite to the electrical compartment 213 in a first direction. Traditional forklifts use lead-acid battery packs. Replacing lead-acid battery packs with sodium-ion or lithium-ion cells can reduce the weight of the battery pack while providing the same power. The weight of the battery pack can be increased by using counterweight 400, which can maintain the stability of the forklift and prevent it from tipping over without changing the forklift structure.

[0084] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the battery system includes an inverted "L"-shaped housing 210 and a battery module 100 housed within the housing 210. A receiving groove 500 is embedded (inserted) into the lower part of the housing 210. A counterweight 400 is positioned at the bottom of the receiving groove 500 and abuts against the housing 210. The counterweight 400 is also positioned at the rear end of the bottom of the receiving groove 500, abutting against the rear side wall of the battery compartment 214 and the bottom end of the electrical compartment 213, thereby maintaining greater stability of the battery pack. The receiving groove 500, instead of a conventional closed housing, facilitates the placement and removal of the housing 210. The counterweight 400 increases weight, maintaining the stability of the forklift without altering its structure, preventing tipping, and allowing battery systems with sodium-ion or lithium-ion cells to be compatible with traditional forklifts.

[0085] In some embodiments of this utility model, the counterweight 400 is formed as a cuboid.

[0086] like Figure 8 As shown, the counterweight 400 is formed into a cuboid. This allows it to stably support the housing 210 and more stably maintain the stability of the battery system.

[0087] In some embodiments of this utility model, the weight of the counterweight 400 is adjustable.

[0088] By adjusting the weight of counterweight 400, the weight of the battery system can be adjusted more precisely, maintaining the stability of the forklift.

[0089] Furthermore, the counterweight 400 includes a housing and filler disposed within the housing.

[0090] The weight of the counterweight 400 can be adjusted by changing the quantity or type of filling material inside it. The filling material can be sand, steel balls, metal blocks, etc.

[0091] In some embodiments of this utility model, the counterweight 400 and the receiving groove 500 are detachably connected.

[0092] The counterweight 400 is detachably connected to the receiving slot 500, allowing for easy replacement of different counterweights 400 to match different housings 210.

[0093] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
