Changes
The above pie chart displaying various factors has effect on battery charge and discharge. The numbers indicating the distribution of patents in that area are from selected list of patents. The distribution of patents is based on technology focused in the patent.
* '''Power generation''': Technologies disclosed in patents for modes of power generation in HEV for charging the battery and ways of handling them.
* '''Power management''': Technologies disclosed in patents for managing the battery balance during power generating and/or consuming.
* '''Fluctuating HEV operating mode''': Technologies disclosed in patents for managing battery balance during fluctuating operating modes, especially in composite HEV.
* '''Power supply''': Technology disclosed in patent for starting engine with auxiliary battery current when main battery current is not sufficient to start engine
=== IPMap ===
'''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.
