Tesla has quite a few patents regarding the design of their pack. This thread on TMC has details on a few: http://www.teslamotorsclub.com/showthread.php/17456-Amazing-Core-Tesla-Battery-IP-18650-Cell Very few of them have much to do with the basics of assembling cells into a large pack, but rather how to do so as inexpensively as possible and how to do so while keeping the pack from blowing up show a cell or two explode. Most of the patents I've seen are rather non-obvious in nature. -Dave _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
