Beijing new high power load
Temperature Zhengkao last for days, increasing the power load in Beijing yesterday, a new high power, maximum load reached 16.66 million kilowatts, up 17% last year to increase the maximum load, this is the 7th year, the maximum load refresh the record. The impact of continuous heavy load electricity is not only a strong test of the grid, but also test the city’s operational management.
Electric power technology is the car of the future Studio 14 battery
Oil energy to reduce air pollution, the advantages of zero-emission electric cars more and more prominent. Mushroomed, has introduced electric vehicles.
Volkswagen’s future power technology blue-e-motion cell system is in 180 lithium-ion battery modules 30 battery modules, a capacity of 26.5 kwh. Battery system installation to be compatible with the vehicle’s structure. Application of the golf car motor, maximum power is 85KW, the maximum torque of 270NM, electric golf car with the aerodynamic characteristics of a very well drag coefficient of only 0.295, the maximum speed of up to 135 km / hour.
Also far behind other auto makers, BMW’s E-MINI and other electric cars expected Studio 1435 battery Studio 1436 battery .
In response to the State for “low carbon” call, have opened around the construction of electric vehicle charging station. It was learned that Shanghai has built Caoxi charging station, an area of 400 square meters, located nine charge parking spaces. Beijing, Guangdong, Zhejiang, Jilin, Hubei, Shaanxi and other provinces, were all planning several pilot projects of large and medium sized power stations, also plans to supply outlets, government offices, public buildings and residential quarters and other areas of the parking lot Construction of AC charging pile. A fiery being, appears to have electric cars are not far away from us.
Electric vehicles still a long way away from us
China’s great regional cities, most electric cars only 100 km driving range. 150 km of life, such as turn on a half circle in Beijing are not enough; the requirements of Chinese users of the car is full, not that travel, at least from Guangzhou to Shenzhen to open a session to be able to meet demand, but the life issue is not resolved, just arrived have a problem; In addition, the Chinese family living in dense, small number of private garage, the family charged basically unrealistic. Unless the charging stations to be popular residential area, but it is too early Studio 15 battery Studio 1535 battery .
Since the chemical characteristics of lithium-ion battery for several minutes, the fast charge is often only sufficient to power about 50%. If you try to achieve high speed on the driving, which means a gap will have to stop every charge. “No charge several electricity, the battery is broken.” 15 minutes in the fast-charge conditions, the cell damage is very serious. Can be said that the battery technology is not mature enough, charging stations will be considerable development constraints.
Beijing will in the space bridge, Ma F, small business, benefits, etc. to open four built electric car charging stations. Beijing Municipal Bureau of Quality Supervision issued “electric vehicle power supply and battery charging station technical specifications to protect” standard technical guidance documents, provides the city charging station classification, function, composition, technical requirements and site requirements.
The standard battery storage of energy under the power, charging service capacity will be divided into four charging stations. In which a battery charging station is not less than 6,800 kwh of energy storage, or distribution capacity of not less than the single 5000 kVA, 200 times a day for more than large and medium commercial vehicles, or 500 more times by using car battery replacement or recharge services provided. The four battery charging station for less than 1700 kwh of energy storage, or one-way distribution capacity less than 1000 KVA, 40 times a day for the following large and medium commercial vehicles, or 100 times the following passenger car battery replacement or recharge services Studio 1536 battery Studio 1537 battery .
Lenovo July 30, 2010 Beijing load a new high of fact. Consider the batteries up to 6800 kwh of electricity load to Beijing in turn increase the number of burden. In addition, China is mainly coal, electric vehicles can not be achieved in Europe the power to choose green energy experience. Electric vehicles, such as speculation it really green yet to be confirmed.
In summary, although the vast charging station, but it is more suitable for electric vehicles of public transport operators, large-scale private electric vehicle charging and discharging a solution not a few charging stations can be resolved Studio 1555 battery Studio 17 battery .
