An insulation monitoring method and system for a traction battery and an apparatus are proposed to solve the problem of how to accurately predict a risk of insulation deterioration of the traction battery before the insulation deterioration occurs on the traction battery, so as to provide an early warning about failures in the traction battery. In this method, data statistics on a large amount of insulation resistance values within a long period of time are collected, and whether the traction battery has the risk of insulation deterioration is determined by analysis based on a data statistical result; and if the traction battery has the risk of insulation deterioration, alarm information is output. In this method, based on data statistical analysis performed on the large amount of insulation resistance values within a long period of time, insulation deterioration can be predicted before the insulation deterioration occurs on the traction battery. This allows a user to perform battery maintenance in time before the insulation deterioration occurs on the traction battery, so as to prevent traction battery failures.

There is provided a vehicle control device including: an inverter that is configured to drive an electric motor; a DC/DC converter that is configured to step down a voltage output from a high voltage battery; a pre-charge circuit including a pre-charge switch; a voltage detector that is configured to detect an input voltage input to the inverter and the DC/DC converter; and a controller. When the input voltage is lower than the input voltage at the time when pre-charge of the inverter is completed, the controller is configured to determine that power supplied from a power supply of the DC/DC converter to the DC/DC converter is not normally stopped.

Systems and methods may coordinate and provide bidirectional energy transfer events between electrified vehicles and households or other structures, such as for supporting transient loads associated with the households/structures, for example.
