A satellite-borne high energy cosmic ray detector planned to be launched in the end of 2015, named DArk Matter Particle Explorer (DAMPE), is being developed in China. The BGO Calorimeter, which contains 308 BGO (Bismuth Germanate) crystal bars and 616 PMTs (photomultiplier tubes), is a critical sub-detector for measuring the energy of cosmic particles, distinguishing positrons/electrons and gamma rays from hadron background, and providing trigger information. It contains 1848 signal channels and a complex readout system with 16 front-end electronic (FEE) boards. From year 2013 to 2015, a qualification model and a flight model for the BGO Calorimeter, together with its readout electronics, were successfully developed and passed ground-based cosmic ray tests and a series of qualification level environmental tests. Four test beam experiments for the DAMPE Qualification Model were carried out with the CERN PS and SPS facilities, which proved the major specifications of the BGO Calorimeter, such as energy range and resolution, and the capability of its readout electronics. The progress and some details related to the high reliability design and quality control for the readout electronics will be introduced in this paper.
