Evcome New Energy Co., Ltd., a charging pile company in Guangzhou and Shenzhen, focuses on one-stop research and development, production, sales, installation and service of charging power modules and charging piles. Focusing on the industry chain in the field of new energy vehicles, it is mainly engaged in the construction and operation of electric vehicle intelligent charging systems (AC and DC charging piles, charging modules), and charging stations. AC power supply methods Commonly used AC power supply methods in power distribution systems are: 1. Three-phase three-wire system. Divided into delta connection (0.4kv motor and lighting) and star connection (for low-voltage three-phase 0.23kv industrial lighting distribution and 0.23kv three-phase motor). 2. Three-phase four-wire system. Used for 0.4kv/0.23kv low-voltage power and lighting hybrid power distribution. 3. Three-phase two-wire one-ground system. It is mostly used for rural power distribution (because of safety issues, it has long been eliminated). 4. Single-phase single-wire system 27.5kv. Commonly used in electric railway traction power supply. 5. Single-phase two-wire system 0.23kv (obtained from three-phase four-wire system). It mainly supplies electricity for residents. DC power supply mode Commonly used DC power supply modes in power distribution systems are: 1. Two-wire system. It is used for power supply of urban trolleybus, subway locomotive, mine traction locomotive, etc. 2. Three-wire system. Supply power plants, substations, power distribution stations for their own use, secondary equipment, electrolysis and electroplating. The primary power distribution network is the network from the outgoing line of the distribution substation to the entrance of the distribution substation (or power distribution station). In China, it is also called power distribution network. The voltage is usually 6-10 kV, and most cities use 10 kV power distribution. Charging piles, as charging equipment for new energy vehicles, can be compared to oil and gas tankers for conventional fuel vehicles. Charging piles are usually installed in public construction sites, parking lots in residential communities or beside roads. However, my country's charging infrastructure is not in harmony with the development of electric vehicles. China's new energy vehicle market has exceeded 3.81 million vehicles in 2019, with a global share of 49%. It has become the world's largest new energy vehicle market, providing a huge market for charging infrastructure. The ratio is 3.5:1, which is far from meeting the normal charging needs of new energy vehicles. As the energy supplement infrastructure for new energy vehicles, it is particularly important to increase the configuration of charging piles.
