New ways of solving difficult charge
Resolved by replacing one kind of electric vehicle battery energy supply new model, now complete the experiment in Hangzhou. This “for-electricity” way up “charge” time-consuming long short board, part of the solution electric car “hard charging” a new way.
At the just-completed Hangzhou’s first all-electric car charging stations that can replace the battery box of this, about two computers the size of the main chassis, with a special access jack. Been modified in a car trunk, the operator took only about 3 minutes had loaded it with four batteries , the car immediately leave.
Recently held in Hangzhou, the new energy automotive industry development forum, the Zhejiang Provincial Committee and Party Secretary Huang Kunming, Hangzhou, said Hangzhou to seize opportunities and accelerate development of new energy automotive industry. At present, Hangzhou has been put into operation and under construction, there are 10 new energy vehicles, with total investment over 50 billion yuan. If all of these enterprises put into operation, each can produce 25 000 new energy vehicles.
Meanwhile, with the service charge to promote the construction of supporting facilities, and the purchase of new energy vehicles and other users of financial subsidy given to a series of supportive policies have been put forward in 2012, Hangzhou actually put to use new energy vehicles will reach 3000 .
Turning to the reasons electric cars more difficult to promote, Hangzhou Electric Power Bureau of the experts said, despite the price, charging is inconvenient for a major.
The current charging the existence of two “shortcomings”: first, long charging time, the general car charge to more than one hour, if you want to charge a short time, then the greater damage to the dell Studio 1535 battery ; second is the limited parking environment. “As long as ordinary car drove off with the oil, and electric vehicles will take a long time charge, the city is hard to find so great a space dedicated to long vehicle parking charge.”
“Through ‘for power’ mode electric vehicle charging problems can be resolved, at present, the program has matured.” The expert said. “In the future, battery manufacturers can put different performance batteries in the box, connected using standard connectors and automotive replacement very convenient, but also help users to choose different quality of the battery.”
Hangzhou Electric Power Bureau Deputy Director in charge of the letter, said Cai, Hangzhou is exploring the car charging network construction mode. Advance in the process of charging facilities, dell Vostro A860 battery need to overcome is the practical problem to solve Hangzhou car charging network distribution.
According to industry analysis, cell design data typically 200-400 km, a top speed of 100-150 km, the situation can only reach about two-thirds of the design desired. Holdings based on market terms, would require at least 25 kilometers per build a charging station.
In this connection, Hangzhou Power Authority proposed the idea that the use of supermarkets, stadiums, public parking lots and other resources, the establishment of charge pile as a supplement to complete the battery charge; in the business area, residential area or mall in the parking lot in achieving distribution and replacement of the dell Latitude D620 battery, as long as the car park to provide a container the size of the venue can be. The future, this model would constitute a low-cost, wide coverage, strong functional battery energy supply infrastructure network.
At present, Hangzhou has established 10 power stations and two charging cradle column, the major professional service vehicles. This year, Hangzhou will build a large power stations, five medium and small power stations, from 50 to 100 battery replacement service outlets and 130 charging pile, mainly serving the community of vehicles. In accordance with the planning of the electricity sector, within 5 years to invest about 500 million yuan to build an infrastructure for electric vehicles to meet the 5000 demand for electric vehicle charging.
At present, the Hangzhou Government plans electric vehicle industry into a strategic and pillar industries to stimulate low-carbon city development in Hangzhou. Hangzhou, the government official said the next step, Hangzhou government will entrust the drafting of Hangzhou, Hangzhou Electric Power Bureau of model car charging network distribution planning, and programs into the urban planning, balanced, comprehensive layout, built up in Hangzhou Charging service network.
