Claims

[1] Fastening device for battery cells, characterized by that it includes: a mounting seat; two clamping plates (1) which are provided opposite one another and sliding on the fastening seat, wherein a receiving area for fastening a battery cell (4) is formed between the two clamping plates (1), wherein the clamping plates (1) are provided in the interior with a first cavity channel for receiving coolant; a drive pump (2) connected to the first cavity channel of each of the two clamping plates (1), the drive pump (2) serving to pump the coolant in a direction facing the first cavity channel. [2] Fastening device for battery cells according to claim 1, characterized by that the clamping plate (1) has a hollow structure, wherein a hollow chamber within the clamping plate (1) is configured as the first cavity channel. [3] Fastening device for battery cells according to one of the preceding claims, characterized by that the clamping plate (1) is provided internally with a serpentine channel, wherein the serpentine channel is configured as the first cavity channel. [4] Fastening device for battery cells according to one of the preceding claims, characterized by that the clamping plate (1) is provided with an inlet opening and an outlet opening (11) which are connected to the first cavity channel, wherein the inlet opening is connected to the drive pump (2). [5] Fastening device for battery cells according to one of the preceding claims, characterized byin that the clamping plate (1) comprises a first portion and a second portion, wherein the first portion is provided with a recess on a side facing a receiving space, wherein the second portion covers the recess and cooperates with the recess to form the first cavity channel; wherein the second portion has a thickness of 1 mm to 5 mm. [6] Fastening device for battery cells according to one of the preceding claims, characterized by in that the clamping plate (1) comprises a first portion and a second portion, wherein the first portion is provided with a recess on a side facing the receiving space, wherein the second portion covers the recess and cooperates with the recess to form the first cavity channel; wherein the second portion is a flexible element made of an impermeable, flexible material. [7] Fastening device for battery cells according to one of the preceding claims, characterized by in that the fastening seat comprises a locking element and a guide element, wherein two of the clamping plates (1) are provided slidingly on the guide element, wherein the locking element is detachably connected to the guide element, wherein the locking element serves to lock two of the clamping plates (1) which are clamped on both sides of the battery cell (4). [8] Fastening device for battery cells according to claim 7, characterized by in that the guide element comprises a screw (31) and the locking element comprises a nut; wherein two of the clamping plates (1) are provided slidingly on the screw (31), wherein the screw (31) is screwed to the nut on an outer side of each of the two clamping plates (1), and wherein the nut serves to press the adjacent clamping plates (1) together. [9] Fastening device for battery cells according to claim 7 or 8, characterized by in that the guide element comprises two guide rails (32), wherein two of the clamping plates (1) are provided slidingly on two of the guide rails (32), wherein two of the guide rails (32) are located on both sides of two of the clamping plates (1); wherein a distance between the two guide rails (32) is equal to the width of the battery cell (4). [10] Fastening device for battery cells according to claim 7, 8 or 9, characterized by in that the guide element comprises two guide rails (32), wherein two of the clamping plates (1) are provided slidingly on two of the guide rails (32), wherein two of the guide rails (32) are located on an underside of two of the clamping plates (1); wherein the distance between the two guide rails (32) is smaller than the width of the battery cell (4).
