An improved battery unbalance mitigation in a voltage conversion system is disclosed.The voltage conversion system includes a first and a second battery being connected in series with each other, and a converter having a converter input and a converter output, wherein the converter input is connected to at least one of the first and the second battery. The voltage conversion system further includes a voltage conversion system output being connected to one of the first and the second battery, and to the converter output, thereby producing a voltage conversion system output current I sys out . According to the present invention, a determination if a charging level unbalance in the voltage conversion system is present is based on the voltage conversion system output current I sys out . If an unbalance is present, a first charging current I b 1 is applied to the first battery and a second charging current I b2 is applied to the second battery, where the first and the second charging current I b 1, I b2 are different from each other. |
