There is provided a battery management system for an electric vehicle. The battery management system comprises a first load connector, a second load connector, a first switch, a first battery connector, a second battery connector and a control unit. The first load connector is connectable to a first group. The second load connector is connectable to a second group. The first battery connector is connectable to a first battery. The second battery connector connectable to a second battery. The battery management system is adapted to transfer electric energy from the first battery via the first switch to the first group and to the second group. The battery management system is adapted to connect the second battery to the second group. The control unit is configured to receive a signal representative of a dangerous situation for the first battery. The control unit is configured, in response to the signal, to switch the first switch to disconnect the first battery from the first group and from the second group, and to start transferring electric energy from the second battery to the second group.
