A pressure regulator and a method for regulating the same is for predicting occurrence of dew condensation inside components of a vehicle so that the cause of the occurrence of dew condensation is removed in advance before occurrence of dew condensation. The pressure regulator includes a case in which an opening is provided at one end of the case, an outlet is provided at the other end of the case, and the opening is provided to be inserted into a housing of the component, a fan provided inside the case and a filter provided inside the case, the filter allowing gas to be discharged from the inside of the component to the outside of the component while blocking inflow of moisture from the outside of the component to the inside of the component.

A hybrid electric vehicle (HEV) includes: a battery, a hybrid starter generator (HSG) starting an engine, and a controller that identifies a state of charge (SOC) of the battery upon when a reverse gear input is detected, determines whether to charge the battery by the HSG based on the identified SOC of the battery. In particular, the controller controls battery charging in a charging control mode based on a SOC level of the battery when it is determined that the HSG needs to charge the battery.

Hybrid electric vehicle and charge control method therefor

A system for managing a battery of a vehicle may include: a temperature sensor measuring temperature of external air; an electric device cooler including an electric device mounted in the vehicle, an electric device cooling pipe through which cooling water for cooling the electric device flows, and a first pump circulating the cooling water; a battery cooler including a battery and a battery cooling pipe through which the cooling water for cooling the battery flows; one or more 3-way valves connecting or disconnecting the electric device cooling pipe to or from the battery cooling pipe; and a controller configured to control the first pump and the one or more 3-way valves to move the cooling water in the battery cooling pipe to the electric device cooling pipe when the measured temperature of the external air is the predetermined temperature or less.

Disclosed is a system and method of controlling an inverter to reduce noise in an eco-friendly vehicle. In the method, at least one of a current motor torque and a current motor speed is monitored in real-time. It is determined whether or not the at least one of the current motor torque and the current motor speed corresponds to a noise occurrence range set to a current switching frequency. A changed switching frequency value corresponding to the at least one of the current motor torque and the current motor speed is calculated when the at least one of the current motor torque and the current motor speed corresponds to the noise occurrence range. A PWM signal is generated using the changed switching frequency value to control an inverter.
