| 摘要 |
The present invention relates to a battery charging system (1) for a vehicle. The system comprises an electric power source (2) adapted to delivering a charging voltage to at least one battery (3) with one or more resistance-causing units (R, RL) connected to the system. The system (1) further comprises a regulator (4) adapted to continuously receiving a value which represents a charging voltage (Vd) desired at the time and a value which represents a battery voltage (Vbat) at the time for the at least one battery (3), and to using these values as a basis for continuously calculating a charging voltage (Vcalc) delivered from the electric power source (2) and required for achieving said desired charging voltage (Vd), which regulator is adapted to generating a control signal (S) which contains the control command to the electric power source (2) to deliver the calculated charging voltage (Vcalc). The invention relates also to a method in said battery charging system (1) and to a computer programme product. |
