Volkswagen electric vehicles pursue low-cost with high public return by abandoning battery




"German government now did not make any Guli to buy electric autocar, China in this regard is running away with the forefront." At the recent Da Zhong Dian Qudongjishu exchange Hui Shang, the mass of technical experts from Germany to China New Energy car full of praise to encourage policies. In the mass popularization of electric vehicles globally ambitious plan, China has played a supporting role. 2013, the public electric vehicle production in the world, China has become the ideal market for electric vehicles in the test base.

According to the mass of technical experts, China's subsidies to buy electric cars up to 6 yuan (6,500 euros), which is a higher figure. In Europe, Denmark, as the voice of the most popular electric car country, tax relief for up to 30,800 euros, Britain, France and Spain up to 6,000 euros, Portugal is € 4,500; in Asia, second only to Japan, China, the amount of subsidy, which cycling subsidies up to 11,000 euros.

China's market capacity is far from comparable in Japan and Europe, which is the general public to promote electric cars plan to China as the first choice for an important reason. In this exchange meeting, the public has brought 5 with a new technology for future models. Including Up electric concept car, golf and Long Yat electric vehicles, and the public with Tongji University to develop new leaders Yu hybrid fuel cell vehicles and the Touareg.

To electric vehicle, for example, the car driven by a motor, the maximum power of 85 kW / 115 hp, continuous output power of 50 kW / 69 hp and maximum torque of 270 cattle • meters. Drive vehicle is the energy stored in the capacity of 26.5 kWh lithium-ion battery, the battery component of the weight of 315 kg. The car from rest to 100 km per hour acceleration time of just 11.8 seconds, the maximum mileage up to 150 km.

Golf electric vehicle using an integrated electric drive system, its core components, including weighing about 80 kg of the motor and transmission and differential. Energy management through the integrated drive system for high voltage pulse inverter. The power inverter integrates a DC / DC converter with 12V car power supply and charging devices together constitute a set of integrated drive unit.

Although the public electric vehicle technology in the forefront of the world, but the most polluting electric car - battery manufacturers, he was the general public to give up. Earlier, China's executive vice president of public Sui Zhang said the new, to purchase car batteries in China. The public have signed a Memorandum of Understanding with the BYD plans to cooperate in the battery area and is close attention to the domestic automotive battery production line building. Battery manufacturing and recycling process based on the high pollution, many multinational companies and battery manufacturers are used to establish a joint venture or global sourcing approach, to get the car battery. This of course is in line with corporate and national environmental policy is best to consider, and the determination not to form part of the production of pollution and environmental damage, has been the consensus of the world's multinational corporations.

Currently the highest performance, the most stable car battery is a lithium ion battery. According to the general public that the Chinese is one of the most important producing areas of lithium. Conservative estimates, the global lithium reserves in 2050 will consume 51%. This also means that if can not find a better raw material for the manufacture of batteries, electric car battery supply will be a problem in the future, while the environmental damage caused by mining, combined with the battery, the formation of the pollution of coal power generation, electric vehicles popular may also bring about various environmental problems.
