1 The technical bottleneck of the pure electric vehicle is breaking through day by day. Academician Ouyang Minggao introduced it on January 20, 2018 in the China Electric Vehicles Centenary Forum (2018). The current Chinese high-end battery used in 2020 is ? Three yuan, the negative silicon carbon technology route, the monomer specific energy can reach 300 watt-hours / kg, and PACK can reach 210 watt-hour / kg, the safety indicators have all passed the national standard.
2 The BYD SUN, Dongfeng Fengshen and other models have completed a taxi mileage of 350 kilometers. It can be understood that by 2020, all taxis nationwide will be electrified (a continuous mileage of 450 kilometers) can be achieved.
3 At present, national and social investment institutions are more concerned about public charging stations. Public charging stations can meet buses. After the full success of pure electric vehicle technology, the contradiction in charge infrastructure construction is particularly prominent. The public charging station is the charging requirement for private cars (electric vehicles). The public charging station is positioned for fast charging (replenishment) to facilitate the charging of private cars (electric vehicles), but also rely on the slow charging based on 220V household electricity, portable DC (one hour, can charge 10 kWh). The current problem is that the relevant departments have not yet realized this charging technology.
