Beschreibung
Zusammenfassung:	The invention provides a battery system and an electric vehicle, and the battery system comprises a first battery pack, a second battery pack and a converter. And the first battery pack and the second battery pack are connected in series and are electrically connected with electric equipment, i.e., the first battery pack and the second battery pack are connected in series to discharge at higher voltage. The positive electrode end of the first battery pack is electrically connected with the positive electrode end of the charger, the negative electrode end of the first battery pack is electrically connected with the negative electrode end of the charger, and the first battery pack is charged through the charger; the charger charges the energy storage element in the converter firstly, then the energy storage element in the converter charges the second battery pack, and the charger charges the second battery pack through the converter, that is, during charging, the first battery pack and the second battery pack a
