The apparatus has at least two charging connections. Each of the charging connections has a communication port for exchanging data with the vehicle connected to the charging connection. The communication port of each of the charging connections is coupled to an assigned first communication device, which is designed for communicating with a corresponding first communication device of the vehicle connected to the relevant charging connections, based on a pulse-width modulated signal transmission. A second communication device is coupled via a coupling point to communication ports of all charging connections to communicate with a corresponding second communication device of a vehicle, based on digital data transmission. A compensation unit is wired in between the coupling point and the first communication devices, which is designed to generate a counter-phase signal to a signal that is transmitted from a transmitting first communication device to the assigned communication port and to apply it to the coupling point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for charging an energy storage unit of one or more electrically operated vehicles","description":"An apparatus is provided for charging an energy storage unit of one or more electrically operated vehicles.
