Does the charging pile market require a power module of 30 kW or more?
Learn more about the technical trends and reference designs for the June 2016 Smart Car Journal . On June 23, Shenzhen Charging Pile Exhibition, many friends are asking a question from the old generation. At present, there are 3KW, 7.5KW and 15KW modules on the market. Is it necessary to develop modules with 30KW or higher power in the future? For professional charging pile rectifier module manufacturers, to answer this question, we have to analyze this problem from two aspects: First: the development trend of electric vehicles in the future, how to respond to the requirements of electric vehicles better as a DC fast-filling pile as a supplier? Second: What are the expectations and requirements of the fast charging pile customer for the charging pile module? First of all, let's talk about the development trend of electric vehicles in the future. At present, most electric vehicles consume about 20 kilometers of electricity. The main purpose of electric vehicles is to commute in the city. The average person does not use electric vehicles for long distances. Travel, cruising range of 300-400KM has already met everyone's urban travel demand for electric vehicles, and with the use of high-efficiency electric drives and air conditioners, synchronous motors, there will still be room for power consumption in the next 100 kilometers, in this case, The battery capacity of an electric vehicle can meet the needs of most people by achieving 80 degrees of electricity. The current fast charging speed of 30-50 minutes, with the advancement of rapid battery charging technology, it should be more reliable to achieve full power in 12 minutes in the future. That is to say, the capacity of the future charging pile can be controlled at the maximum. About 400KW. According to the evolution of Volkswagen's future charging pile power, the power of the charging pile will rise from 50KW to 350KW: The ultimate goal of Volkswagen is to have an electric car to do the user experience of the fuel car. In May of this year, the old generation traveled for two weeks in Leipzig, Hamburg, Munich and other cities in Germany. Due to the small promotion of electric vehicles by the German government, the installation quantity and system compatibility of charging piles are far less than those of domestic cities such as Beijing and Shenzhen. .
