PURPOSE: A preventing method of a sub battery for a hybrid vehicle is provided to control an initial LDC output power(current) without a current sensor for preventing an overcharging of the sub battery. CONSTITUTION: A preventing method of a sub battery for a hybrid vehicle comprises the following steps: outputting an LDC(13) output power smaller than the maximum output power; calculating a voltage value of the sub battery(15); determining whether the voltage value of the sub battery is over the standard value; reducing the LDC output power if the voltage value is over the standard; and increasing the LDC output power if the voltage value is under the standard. |
