Generator controller used in hybrid electric vehicle |
摘要 |
The battery current is sampled and accumulated for T seconds (102,104). The obtained accumulated value is used to determine the control target Pg of the generated power. Since the generated power is controlled according to the accumulated current of the battery which fits the characteristic of the battery (14) compared to the charged-and-discharged power, state of charge (SOC) of the battery (14) can be more accurately controlled within the target zone. When the SOC of the battery (14) is initially outside the target zone (116), the SOC is adjusted within the target zone by forcibly discharging (112) or charging (118) the battery (14). The precision of SOC control can be improved compared to when the SOC of the battery (14) is controlled using the charged-and-discharged power. <IMAGE> |
