This allows an intelligent calculation of the charging cur-rent provided to the vehicle, and the charging process is optimized. Themeasured values read are included in the charging current specification. Thefollowing graphic shows the schematic structure of the system.Fig. 5-8: Modbus TCP system overview1 ...

External meter (house connectionmeter)InformationThe illustration provides an exemplary system overview and does not in-clude all the necessary ancillary equipment required for safe operation ofthe equipment (e.g. line circuit breaker, residual-current device ...).Domestic Connection MonitoringBy means of the domestic connection monitoring, the charging vehicle canbe dynamically provided with the respective available charging current, de-pending on the remaining consumers on the house connection. This ensuresthat the domestic connection safety device is not overloaded, and that it isnot always necessary to select a lower charging capacity than would be pos-sible with the vehicle and the installation.Via the meter 5, the charging station can read out the entire current energysupply from the power grid. Based on this information and the value of thepost-meter fuse 4 (maximum charging current, which is specified by the
