Boost control method and system for boost converter

A system that controls boost, comprising:

• a processor configured to:
• analyze a battery state before a boost, and determining a normal state;
• execute a first boost mode via the boost converter to primarily boost up a voltage of a bus terminal, when the battery state is determined to be normal;
• analyze situation data during the primary boost, and determining an abnormal state of the bus terminal;
• and
• execute a second boost mode to increase a voltage of the bus terminal up to a final target value, when the bus terminal is normal.

A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:

• program instructions that analyze a battery state before a boost, and determining a normal state;
• program instructions that execute a first boost mode via the boost converter to primarily boost up a voltage of a bus terminal, when the battery state is determined to be normal;
• program instructions that analyze situation data during the primary boost, and determining an abnormal state of the bus terminal;
• and
• program instructions that execute a second boost mode to increase a voltage of the bus terminal up to a final target value, when the bus terminal is normal.
