Abstract: The present invention provides an electromagnetic interference suppression circuit including an isolation module, a transient high voltage suppression module, a common mode rejection module, and a filter module. The isolation module electrically isolates first signals to generate second signals. The transient high voltage suppression module protects the second signals against overvoltage spikes. The common mode rejection module protects the second signals against common mode noise. The filter module filters noise of the second signals, and protects the second signals against signal reflection at output terminals of the electromagnetic interference suppression circuit. The present invention further provides an electric vehicle including the electromagnetic interference suppression circuit.

Abstract: A combo communication terminal has a first communication terminal and a second communication terminal. A switch unit of the second communication terminal has a first end, a second end, a third end and a control end. The control end selectively couples the first end to the second end or to the third end according to a control signal. When a communication link between the first communication terminal and the second communication terminal has been established, a second processing unit of the second communication terminal generates and transmits a first control signal to the control end, such that a first processing unit of the first communication terminal is coupled to a first subscriber identity unit of the second communication terminal via the first port, so that the first communication terminal uses the first subscriber identity unit to perform tasks of communication.
