[0043] In the related art, when assembling the cell module of the energy storage power supply, the energy storage power supply cell needs to be fixed and covered with an insulating plate, the electrode of the cell is exposed from the through hole of the insulating plate, then the bus bar is arranged on the insulating plate and connected to the cell in a predetermined manner, and finally the connecting end of the collection plate is welded with the bus bar. The whole process has many parts, complex process, low efficiency and high cost.

[0044] Please refer to Figures 1 to 4 The embodiment of the present application provides an energy storage power supply 100, characterized by comprising a collection adapter assembly 10, a support 20 and a plurality of cells 30. The collection adapter assembly 10 comprises an insulating plate 11, an electrical connector 12 and a collection plate 13. The insulating plate 11 is formed with a plurality of through holes 111 for exposing the electrodes 31 of the cells 30 of the energy storage power supply 100. The electrical connector 12 is fixed on the insulating plate 11 and connected to the through holes 111 in a predetermined manner. The collection plate 13 comprises a connecting terminal 131 electrically connected to the electrical connector 12. The plurality of cells 30 are installed on the support 20, the collection adapter assembly 10 is installed on the side of the support 20 away from the cells 30, and the plurality of cells 30 are electrically connected to the electrical connector 12 of the collection adapter assembly 10.

[0045] The collection adapter assembly 10 provided in the application is integrated as a whole by integrating the collection plate 13, the electrical connecting piece 12 and the insulating plate 11, and when installed and used, only the whole collection adapter assembly 10 needs to be connected with the battery cell 30, thereby effectively reducing the number of materials during the assembly of the battery cell 30 module, facilitating the management and control of the materials, reducing the complexity of the assembly process during the assembly of the battery cell 30 module, being conducive to improving the assembly efficiency and reducing the labor cost, and meanwhile, being conducive to improving the neatness of the finished module. In addition, the collection adapter assembly 10 is installed on the outer side of the support 20 and electrically connected with the battery cell 30, thereby facilitating the subsequent maintenance and replacement of the collection adapter assembly 10.

[0046] Specifically, please refer to Figure 2 and Figure 3 In the embodiment of the application, the support 20 includes an upper support 21 and a lower support 22, and a cavity is formed between the upper support 21 and the lower support 22 for mounting and fixing a plurality of battery cells 30. Further, a plurality of connecting columns are arranged on the lower support 22, the plurality of connecting columns are arranged close to the side wall of the lower support 22, and the plurality of connecting columns are arranged at intervals.

[0047] Further, in order to further fix the battery cell 30, a fixing glue can be added into the housing, so that the battery cell 30 is fixed more firmly and the stability of the battery cell 30 is enhanced. When the energy storage power supply 100 is subjected to impact or vibration, the structural glue can absorb part of the impact force, thereby reducing the impact on the battery cell 30 and avoiding leakage or even explosion caused by excessive impact on the battery cell 30 and internal electrolyte oscillation. Preferably, the fixing glue can be a heat-conducting silicone glue with good heat-conducting effect, so that the heat-conducting silicone glue can absorb and transfer the heat generated by the battery cell 30 during work to the housing, thereby dissipating heat and being conducive to reducing the working temperature of the battery cell 30 and avoiding safety hazards caused by excessively high temperature of the battery cell 30.

[0048] In some embodiments, the support 20 can be replaced by a CTP housing, that is, an external housing of a power battery pack manufactured by using CTP technology. CTP, that is, Cell To Pack, is an advanced power battery pack manufacturing technology. It eliminates the battery module assembly link in the manufacturing process of the traditional battery cell 30-module-pack, directly assembles the battery cell 30 (especially the square battery cell) into the housing, greatly reduces the intermediate module components through high-integration structural design, reduces the overall weight of the battery pack, and improves the volume utilization rate and production efficiency of the battery pack.

[0049] Please refer to Figure 3In the embodiment of the present application, each battery cell 30 has two electrodes 31, which are positive and negative electrodes 31 respectively. In the embodiment of the present application, the positive and negative electrodes 31 are arranged at the same end of the battery cell 30, and the electrodes 31 of the plurality of battery cells 30 are arranged towards the same side.

[0050] Further, the two electrodes 31 are arranged as two protruding columns with different shapes or sizes, so that the positive and negative electrodes of the battery cell 30 can be distinguished according to the shapes or sizes of the protruding columns, thereby improving the accuracy of the installation and connection of the battery cell 30.

Of course, the protruding columns can also be other shapes, which are not limited here.

[0052] In other embodiments, the electrodes 31 of the battery cell 30 can also be arranged at both ends of the battery cell 30, at this time, the number of the collection adapter assemblies 10 should be two, and the two collection adapter assemblies 10 are arranged on the sides of the upper bracket 21 and the lower bracket 22 away from the battery cell 30.

[0053] Please refer to Figure 1 and Figure 4 In the embodiment of the present application, the insulating plate 11 is a PC plate, and a plurality of through holes 111 are formed on the insulating plate 11, the shapes of the through holes 111 are the same as the cross-sectional shapes of the electrodes 31, and the electrodes 31 are exposed from the through holes 111 when the insulating plate 11 is installed on the bracket 20. Further, the insulating plate 11 is provided with adhesive on both sides, and the electrical connecting piece 12 is installed on the insulating plate 11 by adhesion, and the insulating plate 11 is installed on the bracket 20 by adhesion.

[0054] In the embodiment of the present application, the electrical connecting piece 12 is a busbar. The electrical connecting piece 12 can be made of copper, aluminum, nickel or alloy material. After the electrical connecting piece 12 is fixed to the correct position by a tool jig or other means, the electrical connecting piece 12 and the electrode 31 can be welded together by laser welding. It can be understood that the electrical connection between the electrical connecting piece 12 and the electrode 31 can also be achieved by twisting or pressing or other connection methods. Further, the electrical connecting piece 12 is provided with a welding hole for laser welding at the position corresponding to the electrode 31.

[0055] The collection plate 13 is a key component of the energy storage power supply 100, which is responsible for collecting, processing and transmitting various data in the battery pack, such as voltage, current, temperature, etc. In the embodiment of the present application, the connection terminal 131 is a linear structure extending outward from the collection plate 13, and the collection plate 13 is an integrated structure integrally processed and formed.

[0056] Please refer to Figure 4 In some embodiments, the collection adapter assembly 10 further comprises a collection nickel sheet 14, which is arranged at the end of the connection terminal 131, and the connection terminal 131 is electrically connected with the electrical connector 12 through the collection nickel sheet 14.

[0057] In this way, the collection nickel sheet 14 is used to realize the electrical connection between the connection terminal 131 and the electrical connector 12, which is conducive to ensuring that the electric charge can be stably and efficiently transmitted, and improving the structural strength of the connection between the collection line and the electrical connector 12.

[0058] Specifically, the collection nickel sheet 14 refers to a nickel sheet used in the battery pack or energy storage power supply 100 for connecting battery monomers, collecting battery state information (such as voltage, temperature, etc.) and transmitting. Its material is usually nickel or nickel alloy, which has good electrical conductivity, corrosion resistance and certain mechanical strength, and can meet the use requirements of the battery pack in complex environments.

[0059] In the embodiments of the present application, the collection nickel sheet 14 is connected with the connection terminal 131 and the electrical connector 12 by welding, and in other embodiments, the connection mode of the collection nickel sheet 14 with the connection terminal 131 and the electrical connector 12 can also be selected as gluing or screw connection. The specific connection mode can be selected according to actual needs, and will not be described here.

[0060] In some embodiments, the connection terminal 131 comprises a thermal sensitive collection terminal 132.

[0061] In this way, the thermal sensitive collection terminal 132 can be arranged to monitor the temperature of the battery cell 30 at any time, so as to avoid safety hazards caused by overheating of the battery cell 30.

[0062] Specifically, in the embodiments of the present application, the connection terminal 131 comprises a thermal sensitive collection terminal 132 and a voltage collection terminal, wherein the voltage collection terminal is used to collect and monitor the voltage of the battery cell 30, and the thermal sensitive collection terminal 132 is used to collect and monitor the temperature of the battery cell 30.

[0063] Further, the thermal sensitive collection terminal 132 is an NTC thermal sensitive wire harness. The NTC thermal sensitive wire harness is a special wire harness which combines the characteristics of NTC thermal sensitive resistor and is used to measure and monitor the temperature change of the environment or equipment. The working principle of NTC thermal sensitive resistor is based on the negative correlation between its resistance value and temperature. When the ambient temperature rises, the resistance value of NTC thermal sensitive resistor will decrease; on the contrary, when the ambient temperature decreases, the resistance value will increase. This characteristic makes NTC thermal sensitive resistor can be used as a temperature sensor, and the ambient temperature can be inferred by measuring its resistance value.

[0064] In some embodiments, the acquisition adapter assembly 10 further comprises a thermistor nickel sheet 141, which is arranged at the end of the thermosensitive acquisition terminal 132 and electrically connected to the electrical connector 12 through the thermistor nickel sheet 141.

[0065] In this way, the thermistor nickel sheet 141 is arranged to facilitate more accurate measurement of the temperature of the battery cell 30.

[0066] Specifically, the thermistor nickel sheet 141 is usually made of an alloy or an oxide with nickel as the main component. These materials have specific resistance-temperature characteristics, that is, the resistance value changes with temperature, thereby achieving accurate measurement of temperature. In addition, the thermistor nickel sheet 141 can also contain other metal oxides such as manganese, cobalt, copper, etc. to improve its performance or stability.

[0067] The thermistor nickel sheet 141 has high sensitivity to temperature changes and can quickly respond to temperature fluctuations. It is suitable for a wide temperature range from low to high temperature, meeting the use requirements of the energy storage power supply 100 in different environments. At the same time, the thermistor nickel sheet 141 can maintain stable performance under long-term use and different environmental conditions. It should be noted that the relationship between the resistance value of the thermistor nickel sheet 141 and the temperature is usually nonlinear, which may cause measurement errors. In order to obtain more accurate measurement results, nonlinear correction or specific algorithm processing is required.

[0068] In the embodiments of the present application, the thermistor nickel sheet 141 is connected to the thermosensitive acquisition terminal 132 and the electrical connector 12 by welding. In other embodiments, the connection mode of the thermistor nickel sheet 141 to the thermosensitive acquisition terminal 132 and the electrical connector 12 can also be selected as glue or screw connection. The specific connection mode can be selected according to actual needs, which will not be described here in more detail.
