However, the charging station and vehicle also need to communicate with various servers on the Internet. If the vehicle only has to communicate with the charging station for charging, the choice of transmission medium and protocol would be quite flexible. Since these two charging processes each have their advantages and disadvantages, they are used in parallel. In this case, the weight of the charger does not matter, but costs are higher for such a DC charging station. In this case, the charger is located outside of the vehicle, in the charging station, and it generates the DC voltage for charging the batteries. In the second variant, the battery is charged with DC electricity. However, the charger must be installed in the vehicle, which means additional weight. Nearly, any electrical outlet may be used for charging here. First, the battery can be charged with alternating current, which is available in the electrical grid as single-phase or three-phase AC. In charging the batteries, two different procedures can be distinguished. One way to obtain this time is to delay the start of the charging operation by several tens of seconds. To operate the grid so that it is more stable, the energy provider needs time to supply the charging energy. By comparison, a typical citizen in Germany uses an average of 3-5 kWh of daily electrical energy, depending on household size. The power needed for a charging operation lies between 3 kW and 20 kW, or even over 100 kW, depending on the available power connection and charging profile. In a Smart Grid, data is exchanged about power requirements, and the electrical grid can be optimized accordingly. Nonetheless, by introducing an intelligent electrical grid (Smart Grid) and by using intelligent charging, it is possible to avoid overload and grid failure. It cannot be stored as simple as gasoline and be drawn from storage. But the situation with electrical energy differs fundamentally. This might appear to be similar to the model of fueling up at a normal fuel station, where energy is always in stock and is easy to obtain in the form of gasoline.

As soon as the driver plugs in the vehicleвЂ™s charging cable, charging begins at the maximum possible current, and this adds a certain amount of load to the grid. Until now, no consideration has been given to the total power requirement for charging EVs on the electrical grid. in a parking garage, this could lead to a local grid overload and outage. If several charging EVs draw high power simultaneously in one location, e.g. TodayвЂ™s electrical grids require some time to react to such load changes. This plan calls for one million EVs to be on the roads of Germany by 2020.Д¬ommunication within Charger and Motor drive.Д¬harging of EVs can cause a severe load of local electrical distribution networks. According to the вЂњNational Development Plan for ElectromobilityвЂќ by the German federal government, Germany should become the lead market for electromobility. In Japan, there is already the CHAdeMO standard and a charging station network of over 250 stations. In the USA, this is being done in SAE (Figure 1).

In Europe, charging communication is described in the framework of ISO 15118. The connector and cable as well as the charging communication must be standardized for all EVs and charging stations. Widespread establishment of a charging infrastructure can only be properly achieved if all aspects of the charging process are standardized across manufacturers. International Standardization and its Distribution: It has to offer a standardized mechanism for charging the batteries. In the future, a broadly based and standardized infrastructure will be built up for this purpose. while shopping or at work, they can be charged during these times. Since vehicles are parked frequently, e.g. Just a few charging stations are available in public areas вЂ“ as part of model studies. Today, charging of EVs generally takes place at home. What is the need for communication within the charger, battery pack, and motor drive? For Electric Vehicles (EVs) travelling on the road and because of the necessary battery charging times, there is a need for wireless communication between the EVs and the Electric Vehicle Supply Equipment (EVSEs) (charging stations). This is possible because of the two way electricity and information communication between all nodes in the grid. The smart grid is a new concept of electricity supply operation and management that will enable consumers and utilities to better control the electricity usage. The coming intersection between a growing electrified vehicle fleet and desired growth in renewable electricity generation presents an opportunity for synergistic value.
