A system for detecting fine short of lithium ion high voltage battery for hybrid vehicle comprises a current sensor, a temperature sensor, a battery controller or a hybrid controller, a controller, and a warning device. The current sensor detects a no-load condition of a lithium ion battery. The temperature sensor detects a maximum temperature deviation about each lithium ion battery. The battery controller or the hybrid controller detects a voltage deviation between cells of the lithium ion battery. The controller determines whether or not a detected value is in a no-load condition range, a maximum temperature deviation range of the lithium ion battery, and a voltage deviation range of each cell. The warning device is operated if the detected value deviates from the no-load condition range, the maximum temperature deviation range of the lithium ion battery, and the voltage deviation range of each cell.
