Control device for interlocking of running and charging of electric vehicle

The utility model provides a control device for interlocking of running and charging of an electric vehicle. A charging state signal input end C and a vehicle ignition lock state signal input end B are connected with the control end of a switch control circuit, and the output end of the switch control circuit is connected with the control coil of a two-way relay J1; a power supply V+ is connected with a running enabling signal output end F via the normally closed contact J1b of the two-way relay J1 and is connected with a charging enabling signal output end E through the normally open contact J1k of the two-way relay J1; the power supply V+ is also connected with the power supply end A of the switch control circuit through the normally closed contact J1b of the two-way relay J1, an isolation diode D3 and a charging On button K1; and the normally open contact J1k of the two-way relay J1 and a charging Off button K2 are connected in series in a power supply circuit of a control coil of a follow-current relay J2, and the normally open contact J1k of the two-way relay J1 and the normally open contact J2k of the follow-current relay J2 are connected in series between the power supply V+ and the power supply end A of the switch control circuit.
