The charging mode of electric vehicles will be completely changed, and the power supply of the grid will be fully considered to avoid grid overload during peak power consumption. The group has launched research on this intelligent charging mode. According to foreign media reports, with the support of digital and Internet technologies, BMW Group and European power operator TenneT have launched new cooperation to fully coordinate the charging demand of electric vehicles with the carrying capacity of the power grid, while maximizing the use of renewable energy. The cooperation between BMW Group and TenneT makes full use of the standard interconnection technology of BMW I3, so as to properly manage and calculate the time required for charging process. For example, in the case of high grid utilization, electric vehicles may suspend charging or limit charging power. After the power supply bottleneck disappears and returns to normal use value, vehicle charging will return to a faster speed. In addition, the technology also takes into account the available solar and wind energy resources to maximize the charging efficiency. It is reported that this intelligent charging control technology is part of BMW's charging system. This technology enables the communication between cars and each other to fully optimize the charging process. Whether the car owner uses a public charging station, BMW I wallbox or a household power socket, it can supplement the power for electric vehicles. From the technical point of view, this charging technology has advanced technology. It can record and process signals from power grid operators and perceive the status of power grid in real time. In the joint test of BMW Group and TenneT, BMW I3 is able to successfully detect the coming overload of the network and automatically reduce the charging power. In the future, the number of electric vehicles will continue to grow. With the rapid growth of vehicle charging demand, this intelligent charging system can reduce the pressure of vehicle charging on the power grid and the requirements of related infrastructure. BMW Group and TenneT hope to reduce the cost of grid power dispatching through this technology. In Germany alone, the cost is close to 500 million euros a year.
