In general, an electric vehicle driven by a motor and a hybrid vehicle driven by an engine and a motor are essentially provided with a high-voltage battery and a low-voltage battery, and are driven through electricity.

Typically, a high-pressure battery mainly uses a voltage of 100V to 300V DC, and a cooling device is applied to always maintain the temperature due to heat generation at an appropriate temperature, thereby realizing smooth power performance and fuel economy.

To this end, a “high voltage battery cooling control method of a hybrid vehicle” has been proposed as a technique previously proposed.

The cooling device of the prior art is composed of a battery controller, BMS (Battery Management System), and a blower that sucks outside air by being driven through the BMS, and the BMS is driven by the blower to suck outside air, and the sucked outside air passes through a high voltage battery. While taking the temperature of the high voltage battery, it cools the battery so that it escapes to the outside.

At this time, the BMS measures the temperature of the cooling air and the current temperature according to the heat generation of the high-voltage battery, and implements optimal temperature control by varying the appropriate air volume of the blower for each stage. As an example of optimal temperature control, the maximum temperature of the high-voltage battery or A method of controlling the blower by using the temperature deviation between cells of a high voltage battery has been proposed.

However, although the prior art controls heat generation of a high voltage battery by inhaling outside air, there is a problem that it cannot be effectively applied according to a temperature change of the outside air.

In addition, when the temperature is low, there is a problem that a separate high voltage battery cannot be preheated.
