Description

Technical Field

[0001] The utility model belongs to the technical field of battery boxes, and particularly relates to a detachable flame-retardant battery box. Background Technique

[0002] At present, most of the battery boxes of power battery systems are of a single structure made of metal materials. The main reason is that heat is generated during the charging and discharging process of the battery, and this single structure of metal materials is conducive to battery heat dissipation. During the charging and discharging process of traditional power battery systems, there will be a certain temperature difference in the generated heat. The part near the outer wall of the battery box dissipates heat quickly, and the battery temperature is relatively low, while the heat dissipation of the batteries inside the battery box will be blocked, and the battery temperature is relatively high. The generation of the temperature difference will be unfavorable to the stability of the battery system and cause certain harm to the use of the battery.

[0003] If a combustion accident occurs during the charging process of the battery, the temperature of the box body will rise, and the heat generated by the high thermal conductivity metal material will trigger the combustion or even explosion of surrounding flammable and explosive substances, resulting in economic losses.

[0004] Moreover, at present, during the charging process of the battery pack, multiple batteries cannot be uniformly charged and discharged. When operators perform charging operations on multiple batteries, the efficiency is low and the operation is inconvenient. Therefore, in view of the above problems, it is urgent to design a battery box with good flame-retardant performance to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a detachable flame-retardant battery box to solve the problems of low efficiency and inconvenient operation when operators perform charging operations on multiple batteries as mentioned in the above background technique. The following technical solutions are provided: A detachable flame-retardant battery box, comprising:

[0006] A box body, the middle part of the box body is concave to form a containing space, and storage batteries are evenly placed inside the box body;

[0007] Grooves, evenly opened on the inner side walls of the opposite sides of the containing space of the box body;

[0008] Power connection groups, arranged on the other two opposite side walls of the containing space of the box body, and the power connection groups are electrically connected to the storage batteries through wires;

[0009] A partition board, movably inserted in the middle of the two opposite grooves, and one end of the partition board is clamped with the side end of the storage battery.

[0010] The groove further includes a partition board slot, and the partition board slots are evenly opened on the side walls of the containing space of the box body.

[0011] The thickness of the partition board slot is 4-6 mm. The partition board is inserted in the middle of the partition board slot.

[0012] In this technical solution, when charging a storage battery, the traditional method is to connect each individual storage battery in parallel to the charging terminal one by one through wires.

[0013] In this application, the preferred thickness of the partition card slot is 5 mm. When it is necessary to charge the storage battery, first place the storage batteries to be charged evenly inside the box. After the storage batteries are placed, insert the partitions vertically into the partition card slots according to the positions where the storage batteries are placed. After the partitions are vertically inserted into the partition card slots, one end of the partition is clamped on the right side of the storage battery to fix multiple horizontally stacked storage batteries. Finally, connect the storage batteries in parallel in sequence through wires, and finally connect the wires to the power connection group. At this time, the operator can realize the rapid charging of the entire battery pack by inserting the power charging wire into the power connection group. And because each storage battery is uniformly fixed in the box, the charging efficiency of the operator is greatly improved, and the difficulty of the charging operation is reduced.

[0014] In any of the above technical solutions, further, the power connection group includes a lifting lug. The middle part of the lifting lug is U-shaped, and is bent at the end of the U-shape. And the power connection group is fixed to the box by setting bolts at the bent part. A power connection socket is also provided at the middle part of the lifting lug, and the power connection socket is used to connect an external power supply.

[0015] In this technical solution, the power connection group is made of T2 copper material. The power connection group gathers the wires connecting each storage battery uniformly. When it is necessary to rapidly charge the entire battery pack, only need to insert the wire socket at the charging end into the power connection socket to realize the rapid connection of the circuit.

[0016] In any of the above technical solutions, further, heat dissipation holes are evenly opened on the side of the box. The box is made of SMC flame-retardant material, and rib plates are provided at the bottom of the box.

[0017] In this technical solution, setting rib plates at the bottom of the box can enhance the stiffness of the entire box. The box and the partition card slots are both made of SMC flame-retardant material. When a short circuit occurs or a large amount of heat is generated during the charging process of the battery, the flame-retardant material can ensure that the heat generated at the battery and the fire source caused by the short circuit will not cause the entire battery box to burn together, ensuring the safety during charging. And the heat generated during the battery charging can be discharged from the box in time through the heat dissipation holes opened on the side of the box.

[0018] The beneficial effects of the present utility model are as follows: The box body is made of flame-retardant material, and heat dissipation holes are evenly opened on the side of the box body, which speeds up the air circulation during the battery charging process and can release the heat generated during charging to the outside to the greatest extent; and through the inserted installation of the partition board and the partition board slot, multiple groups of batteries can be uniformly fixed and placed. The partition board can be quickly installed according to the number of batteries being charged, which is convenient for uniformly arranging the charging ends of multiple batteries, and is easy to disassemble, greatly facilitating the operator to uniformly operate multiple batteries and reducing the charging time.

[0030] Grooves 20, evenly opened on the inner side walls of the opposite sides of the receiving space of the box body 10;

[0031] Power connection groups 30, arranged on the other two opposite side walls of the receiving space of the box body 10, and the power connection groups 30 are electrically connected to the storage batteries 50 through wires;

[0032] Partition boards 40, movably inserted in the middle of the two opposite grooves 20, and one end of the partition board 40 is clamped with the side end of the storage battery 50.

[0033] The groove 20 further includes a partition board slot 21, which is evenly opened on the side wall of the receiving space of the box body 10.

[0034] The thickness of the partition board slot 21 is 4 - 6 mm. The partition board 40 is inserted in the middle of the partition board slot 21.

[0035] In this technical solution, when charging the storage battery, the traditional method is to connect each single storage battery in parallel to the charging end through wires one by one.

[0036] In this application, the preferred thickness of the partition card slot 21 is 5 mm. When the storage battery needs to be charged, first, the storage battery 50 to be charged is evenly placed inside the box body 10. After the storage battery 50 is placed, the partition 40 is vertically inserted into the partition card slot 21 according to the position where the storage battery 50 is placed. After the partition 40 is vertically inserted into the partition card slot 21, one end of the partition 40 is clamped on the right side of the storage battery 50, thereby fixing multiple horizontally stacked storage batteries 50. Finally, the storage batteries 50 are connected in parallel in sequence through wires, and finally the wires are connected to the power connection group 30. At this time, the operator can achieve rapid charging of the entire battery pack by plugging the power charging wire into the power connection group 30.

[0039] In this technical solution, the power connection group 30 is made of T2 copper material. The power connection group 30 uniformly collects the wires connecting each storage battery 50. When rapid charging of the entire battery pack is required, only the wire socket at the charging end needs to be inserted into the power connection socket 32 to achieve rapid connection of the circuit.
