PURPOSE: Device and method for charging a battery are provided to prevent restart of engine by delaying temperature drop during regenerative brake using a throttle valve and an exhaust recirculation valve applied to a hybrid electrical vehicle. CONSTITUTION: An exhaust recirculation valve(30) is controlled by a specific control signal output from a control instrument(20). And a throttle valve(40) is controlled for increasing an exhausted gas temperature toward an exhaust pipe to improve pressure of suction system during increasing gas temperature to reduce loss in monitoring for returning energy. Further, the control instrument detects a catalyst temperature(13) and reads. In case the redetected catalyst temperature is lower or equal as a minimal activated temperature, an engine is restarted and a specific fuel injection control signal is output to an injector(50) for preventing decrease of purifying efficiency of catalyst. Then an ignition control signal is output to an ignition instrument(60) and the injector injects fuel to the engine with being controlled by a specific fuel injection signal output from the control instrument while the ignition instrument restarts engine by performing ignition flame discharge.
