La présente invention concerne un dispositif de communication par champ magnétique pour un véhicule électrique connecté en utilisant une induction électromagnétique, lequel comprend : un dispositif d'induction électromagnétique qui est placé dans le véhicule électrique connecté et qui réalise une induction électromagnétique en convertissant une puissance continue en puissance alternative, et un circuit résonnant de charge qui est disposé sous la route sur laquelle des pôles d'alimentation sont installés et qui fournit une communication par champ magnétique grâce à l'énergie qui est induite de manière électromagnétique à partir du dispositif d'induction électromagnétique. Conformément à la présente invention, lorsque le véhicule électrique connecté passe au travers des pôles d'alimentation ou s'arrête, une communication est établie entre le véhicule électrique connecté, les pôles d'alimentation et un onduleur. Par conséquent, si un signal est transmis à un circuit secondaire par l'intermédiaire d'un commutateur, d'un capteur et similaire en cas d'urgence, signal qui peut être détecté par le véhicule électrique connecté, l'onduleur reçoit le signal et bloque les pôles d'alimentation.
