The first bluetooth chip 201 includes, but is not limited to, a bluetooth chip such as a BG24 bluetooth chip, which can perform an equivalent data transmission function, and the present utility model is not limited thereto. By providing the data transmission device capable of selecting various first bluetooth chips 201 in this way, it is advantageous to select an appropriate first bluetooth chip 201 according to the actual situation of the data transmission device, thereby improving the applicability of the data transmission device.

In this way, the number of the slave board devices 40 which are required to be assembled into the same energy storage battery container is selected according to actual requirements, so that the application requirements of the energy storage battery containers with different powers and different voltage ranges are met, and meanwhile, through independent connection, independent work among the slave board devices 40 can be realized, and the occurrence of the condition that the rest slave board devices 40 are affected due to the failure of at least one slave board device 40 is reduced.
