Environmental pollution continued difficult, volatile oil and gas prices now, trend of energy really has no choice. Under such a background, the electric car concept has hyped in the world for many years, published last year, Tesla Model s electric car more handsome cool shapes, more reliable performance thanks to price, comparable to gasoline-powered. Domestic related industries but also in its layout.

For electric vehicles, charge efficiency is not hard to solve the problems, but how to charge is a trouble. Use the owner's household power supply for charging the car as far as hundreds of metres away is unrealistic, Depot set to a charging infrastructure require large-scale renovation of infrastructure. The Government and the manufacturer's solution is to build a nationwide network of charging stations, Tesla company in China and the Minsheng Bank, silver taihe of China Unicom and other cooperation in its outlets around the surrounding building post.

But charging station can really solve life problems? And not asked 9.6 million square kilometers land area Shang, especially sparsely populated of Midwest area how construction enough of charging facilities; only in more than 650 multiple size city, built enough of since charging equipment also to completed huge of grid transformation engineering, and occupied large of land, this in land resources tension of City area apparently is serious of waste; stay electric widely universal Hou, in user intensive of line big city, even 5 minutes charging time still will led to near sections of hold blocking, More intensive construction impossible. This series of problems, hard charging for electric vehicles available would severely limit the development of industries.

To mend rather than proactive, solve charging problem may need to look for other ways: electric cars "battery replacement" seems to be a better option than around charging charging. According to population and user density established battery rental stores, by stores advance prepared filling good electric of battery module provides to user replaced using, does can avoid many trouble, according to Tesla of introduced, for Model s electric replaced battery whole process only needed 90 seconds, this greatly reduced has user time, improve has efficiency, also reduced has may of hold blocking; second, compared charging station, battery rental of dot can greatly reduced, land and grid transformation of cost also corresponding reduced. In sparsely populated areas, users can also bring their own battery way of doubling vehicle range, avoid electric short defect. In fact, Tesla company's future plans, the charge station contains a replaceable service.

However, the car battery replaced still has some way to go, on the one hand the vehicle manufacturers are developing their own battery module, between difficulties in harmonizing standards under existing technology, battery replacement is not as simple as a household appliance requires professional and technical personnel. To solve these problems, I am afraid that requires integrated management planning, as well as advances in technology research and development.

In any case, electric vehicle industry has expanded rapidly in the eve of the effective solution to the problem of supporting facilities, accurately choose their development path, out of stumbling blocks on the path ahead, avoid falls halfway, so that the whole industry is subject to individual issues, I am afraid this is management's top priority. Transportation industry development over the years don't match car caused by multiple small, car-less low-level errors, should be a warning.
