'''Approach2:'''[[Image:Nissan2.jpg|thumb|center|1000px|Nissan Motors - Technology Approach2]] '''Findings:''' '''1)''' JP10295045 (1997):- Battery management system, received 21 forward citations from all big names in a span of 5 years and self- cited twice the same technology indicating strong technology strength and building on its own technology. '''2)''' Patent and non-patent information indicate that Nissan’s has focused much on circuit arrangements for charging or depolarizing batteries or for supplying loads from batteries (H02J 7/00). '''3)''' Jointly worked with Sony corp. (1998) developing high power density Li-ion battery for parallel HEV. '''4)''' Proposed a novel charge/discharge control system based on car navigation information.
