Electric vehicle charging stations to carry out the pilot concept surfaced
Ministry of Finance, Ministry of Science, the Ministry of Development and Reform Commission four ministries jointly issued a formal notice to carry out the private purchase of new vehicles to subsidize pilot energy, electricity in the new energy automotive industry chain, the most critical links and undoubtedly the most obvious beneficiaries of the charging station and charge pile construction.
Five pilot cities to urge the charging station
Just look at every side of the road in major cities in less than 5 kilometers to build some gas stations, charging stations will be able to fully understand the importance of the pile with the charge. Industry veteran, said local governments attach great importance to the charging station, charging pile construction, especially in this pilot in Shanghai, Shenzhen, Changchun, Hangzhou, Hefei, these five cities, investors can more clearly see that the local government vigorously charging station, charging the determination of pile construction.
Shenzhen and Shanghai's largest and relatively fast action. Shenzhen from June 1 to officially take effect, "Shenzhen-saving and new energy vehicle demonstration pilot plan", in addition to individuals, community groups and businesses to purchase new energy vehicles in the central financial subsidies granted on the basis of subsidies for supporting infrastructure is also subsidized.
Meanwhile, Shenzhen has also promulgated the "Shenzhen electric vehicle charging system specification", indicates the next two years in the residential parking lots and large shopping malls or high-end hotel car park build a new energy vehicle charging station. Total plans to build bus rapid charging stations of the 25 slow, slow charging official vehicle pile 2500, public fast-charging stations 200, public Slow charge pile 10000!
According to the Shanghai media reported that local government is actively considering the development of related measures, after the formation of the draft has been included to give the consumer prices of less than 20% of the one-time subsidy-free by the license auction process directly on the card registration, etc. . The latest development is the Economic and Information Technology Commission of Shanghai, said Shanghai will invest in the charging station and other equipment for 20% of the subsidy, the future will complete charge pile of nearly 400 construction projects.
The other three pilot cities in the footsteps of this area is not too slow. Changchun, the 4 charging stations will be built next year, 300 charge pile. First electric vehicle charging station located in high-tech zone, the end of June is expected to put into use.
Hefei is the national power grid construction, Anhui province-wide this year, will build five electric car charging stations and 300 charging pile, which was built in Hefei, 4 and 80 charging stations charging pile, in addition, will In Hefei build electric car pilot for pool station.
Hangzhou will build a large scale this year, charging stations, five small and medium sized charging station, 50-100 battery replacement service outlets, 130 charge pile. Hangzhou Electric Power Bureau Deputy Director in charge of the letter, said Cai, Hangzhou is exploring vehicle charging network construction mode. Advance the process of charging facilities, need to overcome the problem is the practical solution to Hangzhou car charging network distribution.
Thus, the charging station and charging columns build electric car industry in the new chain of energy services is very important position in national policy and local government together with support from the charging station will be smooth and fast start performance of listed companies such will also be a corresponding increase.
Charge will be divided three ways
Charging station according to the function can be divided into four modules, power distribution system, charging system, battery scheduling system, charging station monitoring system. Charging station needs a complete power distribution room, the central control room, charging zone, replace the battery area, and battery maintenance between the five parts. Distribution room for the charging station to provide the necessary power, not only to the charger to provide power, but also to meet the lighting and control equipment demand, a change in distribution within the building all the equipment, power distribution monitoring system, control and compensation-related equipment. Central control room for monitoring the operation of the charging stations, and complete management of the report printing. Complete charging of main battery charging function. Replace the battery area is the place the vehicle replacement battery, battery replacement required with equipment, construction should also be used to store spare batteries battery storage rooms. Battery re-equipped group, battery balancing, battery actual capacity testing, battery failure and other emergency work to maintain the battery between.
Charging station to recharge vehicles are generally divided into three ways. One is the ordinary charge, the so-called conventional charge or slow charge, the charging mode, the exchange is now plug in the car, you need 5-8 hours or 2-6 hours, this way more for the exchange of charging, 220V or 380V AC external power supply provided to the electric vehicle car charger, car charger to power by the battery charging. Generally small electric vehicles, plug-in available hybrid electric vehicles (pluginhybridelectricvehicle, PHEV) use more of this approach; The second is the rapid charging, the charging current to be larger, which requires the construction of fast charging stations, it does not require the battery is fully charged, only to meet the needs of you can continue driving, and this charge mode, in 20 minutes to 30 minutes time, only to charge the battery 50-80%, this way more than DC mode, DC charger directly to the ground to give the car power output battery charging, charging electric vehicles and related only to provide communication interfaces. Ground charger general power, output current, voltage range. Some of the ground fast charger also has the charging function; third is battery replacement.
Charging station is expected to be able to recover the 6-year
Charging station costs are divided into three parts: infrastructure costs, the cost of distribution facilities, operational costs. Charging station infrastructure costs from the charger, battery maintenance equipment, charging station monitoring and security surveillance equipment, land acquisition costs.
Now many stations are charging the provincial network construction companies and local government combined, are a lot of land allotted by the Government, land acquisition costs low, in the charging station infrastructure costs of judgments, if the land acquisition cost is 0.
Charging station infrastructure cost and configuration of the number of charger has a direct relationship, assuming there are 10 charging station charger, charger, battery maintenance equipment, charging station monitoring and security surveillance equipment cost of 200 million, 20 million, 20 million, the infrastructure cost of $ 2.4 million.
Distribution costs are relatively fixed charging stations, charging stations and distribution facilities generally include 2 transformers, 1 power distribution cabinet, 1 km 0.4KV cable, 2 km 10KV cable capacity 700KVA more active filter device, charging station distribution costs 192 million.
Charging station operating costs, including staff costs, fees and other station equipment consumed a total of 21 million distribution facility maintenance cost is generally about 3% of distribution costs, about 6 per million.
Cost recovery charging station and battery life actually has a lot of cost recovery charging stations and battery life to do a sensitivity analysis, when the battery life per hour 70KVA, the charging station infrastructure cost recovery period is 6.53 years, the basis of charging stations and distribution facilities to implement recovery period is 11.76 years; when the battery life up half an hour 70KVA, the charging station infrastructure cost recovery period is 3.27 years, the basis of charging stations and distribution facilities to implement recovery period is 5.88 years ; When the battery life to 15 minutes 70KVA, the charging station infrastructure cost recovery period is 1.63 years, the basis of charging stations and distribution facilities to implement recovery period is 2.94 years.
Overall, a single charging station infrastructure and distribution facilities is not a big investment, if the battery life can reach more than half an hour 70KVA, charging station can be controlled in the cost recovery period is 6 years or less. A single charging station infrastructure and distribution facilities investment at 430 million, the first phase of construction 75 charging stations with a total investment of about $ 300 million burden on the national grid is not. Cost recovery period from the charging station, when a half-hour battery life to 70KVA, the charging station infrastructure cost recovery period is 3.27 years, the basis of charging stations and distribution facilities to implement recovery period is 5.88 years, with the ability to enhance battery life , charging stations will reduce the cost recovery period.
National Grid invested heavily in the charging station
When the charging station large-scale construction, the charging station's main function is to achieve the fast charge, slow charge of the functions implemented by the charge pile. Taking into account the area of charging stations, charging stations should be configured ordinary 10 charger.
According to the national grid planning, the first stage of charging station master total investment will reach 300 million yuan, the second phase of 14 billion yuan in the third phase of 18 billion to the charging station master in 2020 the total investment will reach 32 billion yuan . Charging station master in charge, power monitoring systems, active filtering devices in 2010 will reach 1.5 billion yuan investment, 20 million yuan, 63 million yuan, the second phase of the annual average investment size will rapidly grow to 1.44 billion yuan , 1.6 million, 672 million yuan.
2020, a total investment of 12.5 billion yuan charge pile. 2010 charging pile investment 160 million yuan ,2011-2015 charging pile investment 4.5 billion yuan, an annual investment of 900 million yuan, is the first stage investment of 5 times the average.
