Patent number: 11088401Abstract: The present invention is focused on the making of tubular battery pack and integral tubular battery characterised by the use of high energy density lithium-ion cells mounted in thin tubes in shell and tube heat exchanger configuration for thermal management. Each lithium-ion cell is mounted inside the tube and electrically insulated from its wall using external thin washers or internal isolating plate. The remainder of the cell surface is exposed and transfer heat to the inner wall of the tube. A thermal medium is circulated in and out of the shell and over the outer surface of the tubes to maintain them at an optimum temperature range of 0° C. to 50° C. The tube bundle has an integral battery management system a safety relief system. Each tube and shell assembly, is one module within the battery. Multiple modules are connected to form the final battery.Type: GrantFiled: February 15, 2021Date of Patent: August 10, 2021Inventor: Ahmed Tarfaoui
