In technology approach patent and non-patent literature is used to extract information about the technology profile of various assignees such as
Years in this activity
Type of batteries used
Battery charging system
Type of HEV (Series (SHV)/Parallel (PHV)/Composite (SPHVS))
Technology strength based on citation analysis
Product Vs patent identification
Battery management solutions proposed (i.e. current control/cut-off system and SOC detection
technique)
Scientific literature and technology news to strengthen the report, since patent activity is a slow process.
