SYSTEMS AND METHODS FOR POWER MANAGEMENT USING ADAPTIVE POWER SPLIT RATIO

Methods and systems of power management in a hybrid vehicle (100) comprising an engine (101) and a motor-generator (106) are disclosed. A control system (109) of the hybrid vehicle obtains a battery temperature and a catalyst temperature. The control system determines a) whether the battery temperature is within an optimal battery temperature range and b) whether the catalyst temperature is within an optimal catalyst temperature range. The control system determines a power split ratio (PSR) based on the determination of a) and b). The control system controls the engine (101) and the motor-generator (106) based on the determined PSR.
