Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric energy storage, and specifically relates to a matrix stacked full-immersion energy storage device. Background Art
[0002] Most of the existing fully immersed energy storage devices use a closed battery cabinet, and install the battery modules in the battery cabinet according to a certain arrangement. At the same time, an insulating temperature control medium is injected into the battery cabinet, so that the battery modules are immersed in the temperature control medium, and the temperature control medium and the battery module are used for heat exchange to achieve the purpose of temperature control. Specifically, some energy storage devices do not have a temperature control medium circulation system, but only inject the temperature control medium into the battery cabinet to immerse the battery module. Since the battery module is prone to local high temperature during operation, and the efficiency of heat conduction of the non-flowing temperature control medium is low, the local temperature continues to rise, the temperature control performance and the temperature uniformity performance are poor, and there is a risk of thermal runaway. Although some energy storage devices are equipped with a temperature control medium circulation system, due to the large volume and flow area of the battery cabinet, the number of battery modules installed in the battery cabinet is also large, and the fluidity of the temperature control medium in the battery cabinet is poor, forming a dead zone where the temperature control medium does not flow in some areas, which will also increase the temperature of the temperature control medium in the local area, and the temperature control performance and the temperature uniformity performance are poor, and there is a risk of thermal runaway.

[0068] Example 1
[0069] like Figure 1-9As shown, the matrix stacked fully immersed energy storage device of this embodiment includes a compartment 10 and a battery assembly installed in the compartment 10. Specifically, the battery assembly includes at least one layer of battery packs, and the battery pack includes a plurality of battery cells 11, and the battery cells 11 are arranged in n columns along the X direction and m rows along the Y direction, where n≥2 and m≥2. Specifically, the battery assembly of this embodiment is provided with 5 layers of battery packs. Of course, in some other embodiments, the number of layers of the battery pack can also be set to 1 layer, 2 layers, 3 layers, 4 layers, 6 layers and more than 6 layers. In this embodiment, in each layer of battery packs, the array of battery cells 11 is arranged in 6 rows and 6 columns. Of course, in some other embodiments, the number of rows and columns of the array arrangement of battery cells 11 is set according to actual needs, and no further description is given. In particular, when the battery assembly includes at least two layers of battery packs, the arrangement of the battery cells 11 of each layer of battery packs is the same. In this embodiment, the left and right sides of the battery assembly located in the X direction are respectively provided with a left temperature control channel 13 and a right temperature control channel 14 between the compartment 10.
[0070] In the same layer of battery pack, there are inter-row gaps between two adjacent rows of battery cells 11, and between two rows of battery cells 11 at both ends of the Y direction and the compartment 10, and there is an inter-column gap between two adjacent columns of battery cells 11. Specifically, in this embodiment, a pole lug 12 is provided on the front end face or the rear end face of the battery cell 11 perpendicular to the Y direction, and the pole lugs 12 of all battery cells 11 in the same row are provided on the front end face or the rear end face. In this embodiment, the inter-row gap forms an inter-row channel, and the inter-row channel includes a first inter-row channel 15 and a second inter-row channel 16. The pole lug 12 is provided on at least one side wall of the first inter-row channel 15, and the pole lug 12 is not provided on both side walls of the second inter-row channel 16. The inter-column gap between the first inter-row channel 15 and the second inter-row channel 16 forms an inter-column channel 17; in this embodiment, the first inter-row channel 15 is provided independently of the second inter-row channel 16 and the inter-column channel 17. In order to separate the first inter-row channel 15 and the inter-column channel 17, the present embodiment is provided with a first gap partition 18 for separating the first inter-row channel 15 in the inter-column gap. In the present embodiment, the pole lugs 12 of all battery cells 11 are arranged on the front end surface. Of course, the pole lugs 12 of all battery cells 11 can also be arranged on the rear end surface. The principle is the same and will not be repeated. Thus, in the present embodiment, the number of the first inter-row channels 15 is 6, the number of the second inter-row channels 16 is 1, and the number of the inter-column channels 17 is 6. In the present embodiment, the left temperature control channel 13, the right temperature control channel 14, the first inter-row channel 15, the second inter-row channel 16 and the inter-column channel 17 all pass through the upper and lower ends of the battery assembly. Thus, the temperature control medium can flow in the compartment 10 and the battery assembly from top to bottom or from bottom to top through the left temperature control channel 13, the right temperature control channel 14, the first inter-row channel 15, the second inter-row channel 16 and the inter-column channel 17 respectively.

In the two adjacent layers of battery packs, the battery cells 11 of the upper layer of battery packs are arranged one-to-one with the battery cells 11 of the lower layer of battery packs, and the battery cells 11 of the upper layer are located directly above the corresponding battery cells 11 of the lower layer. The second inter-row channel 16 and the adjacent inter-column channel 17 can be connected or independently arranged. In this embodiment, the second inter-row channel 16 and the adjacent inter-column channel 17 are connected, so that in the two adjacent layers of battery packs, a second layer of partitioning members 20 is provided between the corresponding two battery cells 11, and the second layer of partitioning members 20 form a plurality of gap branch channels 29 in the inter-column channel 17, and the gap branch channels 29 pass through the upper and lower ends of the battery assembly. Of course, in some other embodiments, the second inter-row channel 16 and the adjacent inter-column channel 17 may also be arranged independently of each other. In this case, not only is a second gap partition 21 for partitioning the second inter-row channel 16 arranged in the inter-column gap, but also a third layer of partitions 22 located on both sides of the second inter-row channel 16 are arranged in the inter-layer gap. The third layer of partitions 22 are arranged corresponding to the second gap partitions 21 to partition the second inter-row channel 16 and the inter-column channel 17. Of course, in the adjacent two layers of battery packs at this time, a second layer of partitions 20 located in the inter-layer gap is also arranged between the corresponding two battery cells 11.
[0072] A liquid inlet assembly 30 is also provided in the compartment 10, and the liquid inlet assembly 30 is located above or below the battery assembly. The liquid inlet assembly 30 of this embodiment is located above the battery assembly, so that the temperature control medium can flow from top to bottom in the corresponding flow channel by gravity. In this embodiment, the inter-column channel 17 is connected to the second inter-row channel 16, and the liquid inlet assembly includes a left liquid inlet bin 31, a right liquid inlet bin 32, a first liquid inlet bin 33, and a second liquid inlet bin 34.
