By the end of June 2019, the ratio of new energy vehicles to public charging piles in China was 8.7:1, and the ratio reached 3.5:1 when private charging piles were included. At present, the construction of ev charging facilities in China is accelerating expansion, but there is a big problem in the distribution of charging facilities.
The main distribution places of charging piles in China are public underground parking lots, parking places in residential areas and office areas, gas stations or highway service areas. Among them, some places in many regions, such as underground parking lots of shopping malls, have a lot of idle charging piles, while some places with large traffic flow, such as schools and hospitals, have the problem of insufficient charging piles and queuing for charging.
2. fuel cars "occupy" charging parking Spaces
The shortage of parking Spaces in China's cities has long been a problem. In addition, some parking places are out of interest and some owners are not "disciplined" enough, resulting in charging Spaces for electric vehicles often being occupied by fuel vehicles.
In August 2018, a media investigation by Beijing National Radio found that there were 30 charging Spaces for electric vehicles in the underground parking lot on the third floor of Jing Department Store in Beijing, but 12 of them were occupied by fuel cars and three stopped working due to faults, which is not a rare situation in downtown Beijing.

Development trend of China's charging pile industry
Wireless charging technology mainly relies on the charging plate placed underground to emit electromagnetic, and the induction coil on the electric vehicle accepts electromagnetic and uses the electromagnetic conversion principle to charge the on-board battery, which has the advantages of high safety, convenient use and easy installation. In 2017, Continental launched the wireless charging network system for electric vehicles and the lICharge Smart System, making the wireless charging system efficient up to 90% and the electric vehicles can travel 20 kilometers per 20 minutes of charging. In August 2019, BMW announced the information of a wireless charging technology for electric vehicles, and has launched a pilot project in California, the United States. The wireless charging system can fully charge the on-board battery in 3.5 hours, and the power efficiency of the system reaches 85%.
Secondly, 5 g
China has started the construction of 5G networks in 2019 and plans to officially launch commercial services in 2020. The development of 5G technology will also be the key point of this technological upgrade for the automotive DC charging pile industry. It will not only accelerate the construction efficiency of charging pile network, but also improve the user experience of charging pile service and increase the application scenarios of charging pile.

Sharing economy
In this way, private charging pile sharing can meet the charging needs of most electric owners. As of June 2019, there were about 591,000 vehicle (private) charging facilities in China. Assuming that only a quarter of them can be shared, the supply of charging piles is basically close to over 10,000 public charging stations (assuming a single charging station provides 15 piles). Therefore, electric vehicles equipped with DC vehicle charging piles has the potential to become another emerging business in the sharing economy industry.
