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

'''Battery charging system''': The charge to a DC-battery is provided by the generating power from a generator and the regeneration powerfrom the drive motor at the time of braking.
