The main control module is about 91cm long and 28cm wide in general structure, and is actually divided into two parts, namely 56cm long and 35cm long, due to the long size of the main control module, and the two parts are connected by welding two 32pin European sockets (one plate welding female socket and one plate welding male socket). Four-foot fixing seats are welded at the lower right corner of the main control module and used for fixing a multimeter pen. The middle part of the back of the main control module is uniformly welded with 20 40pin European-style female slots for fixing the burning module and the calibration module of each channel; and meanwhile, a plurality of 2pin sockets are distributed beside each European-style female slot and used for connecting with an AC transformer.

Meanwhile, the calibration module is also provided with 6 short-circuit relays, so that 6 short-circuit functions of external products can be realized; and 12 groups of voltage measurement array phases can realize 12 groups of voltage cross tests; and 10 battery cells self-calibration relays are provided, so that the self-test calibration of 10 groups of battery cells can be realized.

d. Hardware connection mode: the back of the main control module is provided with 20 European-style female slots which are arranged in parallel at equal intervals, and the burning module and the calibration module are connected with the European-style female slots on the main control module through European-style sockets to form 10 burning and calibration channels; the burning module and the calibration module of each channel correspond to two adjacent European-style sockets.
