The automotive industry is currently engaged in the biggest transformation of recent years. Electromobility presents a new technological challenge for the automotive industry. In this context, the charging system will play an important key player in the coming years. The requirements for charging systems are very dynamic and diverse from norms, standard and laws as well as from end customers. There is currently no common charging standard for the charging socket worldwide. Worldwide, three charging standards are currently established, which are supported by the European Commission, among others. Here, the individual components and functions charging technologies are systematically described. With this work, the current status for conductive charging technologies and the future trend is summarized. The power consumption of the battery was presented with a measurement result for one charging session.
