The catalytic converter of the vehicle includes: an LNT converter including an LNT catalyst to reduce nitrogen oxides; an SDPF converter including an SDPF catalyst to capture particulate matters and reduce the nitrogen oxides; a connection housing connecting the LNT converter and the SDPF converter to each other; an injection module provided in the connection housing to inject the reducing agent from the LNT converter toward the SDPF converter; an impactor atomizing and vaporizing the reducing agent injected from the injection module; a first guide mixer provided inside the connection housing to form a swirl-direction flow of the exhaust gas mixed with the reducing agent atomized through the impactor; and a second guide mixer provided downstream of the first guide mixer inside the connection housing to form an additional swirl-direction flow of the exhaust gas mixed with the reducing agent.

Catalytic converter of vehicle

A power supply system and method for charging a battery of a vehicle are provided and include a charger that is configured to charge the battery and a charging controller that is configured to receive a voltage to charge the battery and operate the charger. An auxiliary battery is configured to supply a first DC voltage to operate the charging controller and a power supplier is configured to generate a second DC voltage greater than the first DC voltage using external AC power, and to supply the second DC voltage to the charging controller as a driving power source to charge the battery. First and second diodes are respectively installed at output ends of the power supplier and the auxiliary battery, a cathode voltage of the second diode is increased when the power supplier supplies the second DC voltage, and the first DC voltage of the auxiliary battery is blocked.
