These parts are made with a polycarbonate ABS (PC-ABS) thermoplastic polymer blend called Makrolon 6485 which is UL94 rated for high temperatures and flammability, and two of them are required to build one DKblock. So lets look at the parts need for just one battery block and BM board and one PS board, which would be a 7.4V system.Ģ cell holders are required for each DKblock, both holders are identical
For example, a 48V pack would require 7 blocks at minimum, since each block is 7.4V nominal and 7×7.4=51.8VDC. There is one PS board per pack, and there is one BM board per block, and there can be any number of blocks in one pack. There are 3 major pieces of a DKblock system, which are 1) two clamp boards to make one lithium-ion cell block, 2) the Pack Supervisor (PS) board and 3) the Block Manager (BM) board, which talk to each other and manage the system. Let’s look at the major pieces of a DKblock battery pack system, then we’ll look at the parts needed to build one battery block. A DKblock system is made up of one or more battery blocks and a Pack Supervisor printed circuit board. The DKblock is a battery pack building block that combines 18650 cell packaging and a battery management system (BMS) and can be used to build a battery pack from 7.2VDC to 150VDC (and beyond with your custom software) without any welding. This site is dedicated to the open source industrial strength wireless lithium-ion battery management and packaging system called DKblock.
