Concept was popular sauted low-carbon, the decline of the traditional car, people in the coming era of highly anticipated electric car. Let Beijing International Motor Show this year in April or May of the High-Tech Expo, electric vehicles have played an important role, Hp laptop battery many car companies have said that independent research and development of pure electric vehicles already on the market or soon will be, as the core component of the battery is used by many institutions and investors optimistic.
However, if many battery electric vehicles will become a burden on the environment? Geometric money for car battery? The future of electric car battery How to develop? These problems have been increasingly concerned.
Pollution of the lead-acid battery is serious
Case of car batteries, the first thought is no doubt lead battery acid.HP Presario V2000 Battery(compaq v2000 battery), HP pavillion zx5000 Battery(HP hp zx5000 battery), HP PP2200 Battery Yang Yu-Sheng Chinese Academy of Engineering was established: "150 years of experience in lead-acid battery is not fading in Nickel cadmium, nickel hydrogen, batteries lithium new ion battery was launched several years ago, still hold a strong market share, our e-bikes per year around 20 million, most with lead-acid batteries and a variety of diesel throughout the world, everyone is a piece of lead-acid batteries, it is no coincidence."
Lead-acid battery with its mature technology, low cost, high-security benefits of popular support of many car manufacturers, power applications in electric vehicles as a huge market share. But it contains sulfuric acid and lead, it is garbage in one of the most dangerous to the environment a huge pollution problems. Blacksmith Foundation environmental group, said one day: 10 in the world of the most polluting, one of which is the error caused by the removal of lead-acid batteries.
If China is everywhere to see the electric bike, HP PP2200 Battery the battery on most of its lead-acid batteries. battery electric bike is a consumer product, an average of about one year to be replaced by 1. Insiders have revealed that: the remains of lead acid battery current, basically, you can determine the effectiveness of repairs after the new battery for more than 80 percent, effective repair second were more than 50 percent after three no maintenance after the value of the repair. For any brand of electric vehicle batteries, lead acid, and can still be restored, thanks to special technology of repair, re-entered using, the total damage to lead-acid batteries can be repaired, recovered by an advance of qualified marketing and zinc, lead refining regenerated. But this recovery is not always good. There are many recycling activities are illegal, they recovered to lead acid batteries do not have the conditions stored in the open space or a warehouse, there is no qualification process, which causes much waste and waste emissions lead to large scale.
Yu-Sheng Yang stressed that the lead pollution of the environment, mainly in the rear of the merger and the regeneration of the battery. The question is whether the relevant ministries seriously. Lead-acid battery production process control and management of lead contamination must be strengthened.
The high cost of lithium-ion
Compared to lead acid batteries, rechargeable lithium-ion battery with power and energy density, conversion efficiency, long life, lightweight, non-polluting, self-discharge coefficient is small, a wide temperature adaptation of the benefits of electric vehicle battery has become the direction of development. But its high cost, has become the leader of the lithium-ion electric vehicle markets of the kinetic energy of contention.
Shenzhen Ark Electric Vehicle Co., an employee on the ground at the China Joint Business Daily ", said the market for pure electric vehicles is now common to lithium iron phosphate, for example, a lithium iron phosphate 72V / 150AH provides up to 40,000 yuan and even lead-acid batteries offer only a million, the price disadvantage of lithium ion is evident.
And because the battery life is low replacement cost is very high. Most domestic manufacturers of lithium batteries are now one year warranty period without a lithium battery, high quality and free of charge warranty period is only two to three years. Thus, a very ordinary performance of electric vehicles, HP pavillion zx5000 Battery the cost of the battery should be 80 000-10000000, if two or three years after the consumers have to replace the batteries at their own expense, the cost will be enormous.
