Pure electric vehicle battery’s life is long

Battery life of pure electric vehicle, if it is long-life lead-acid battery, generally in 1.5-2 years, if it is lithium iron phosphate battery theoretical life in 7-8 years.

Battery electric vehicles (BEV) are vehicles powered entirely by rechargeable batteries such as lead-acid, nickel-cadmium, nickel-hydride or lithium-ion, or lithium iron phosphate batteries. Although it has a long history of 134 years, it has been limited to a certain range of applications and has a small market. The main reason is due to a variety of types of batteries, generally high price, short life, size and weight of the outside, long charging time and other serious shortcomings.

Is the primary key in the development of electric vehicle batteries, car power battery is the requirements of "low cost", "high capacity" and "high security

O "three requirements. Nickel-metal hydride battery unit weight more than twice as many as lead-acid batteries to store energy, other performance is better than that of lead-acid batteries. Prices for lead-acid battery 4-5 times, are vigorously research make it down. Iron battery USES is rich in resources, low price of iron material, the costs have been greatly reduced, also have a factory. Lithium is the lightest, chemical property is very active metal, lithium-ion battery energy storage unit weight for lead-acid battery 3 times, lithium polymer battery for four times, and lithium resources is rich, the price also is not very expensive, is a very promising battery. In the nimh batteries and industrialization development of lithium ion battery has obtained rapid development. Electric cars, other related technologies, there is a huge progress, such as: ac induction motor and its control, rare earth permanent magnet brushless motor and its control, battery and energy management system, intelligent and fast charging technology, low resistance tires, light weight and low wind resistance body, braking energy recovery and so on, these technical progress to make electric cars became more and more perfect and practical. Air pollution in big cities in our country can not ignore, car emissions is one of the main pollution sources, we have already had 16 cities listed as the world's most serious air pollution in 20 cities. In China today is an average of ten cars per 1000 people per capita, our country automobile holdings into 10 times will increase, oil imports will become a big problem. So the research and development in our country the electric car is not a temporary short-term measures, but is of great significance and long-term strategic thinking.

About life, can't give you reply. At present there are a lot of publicity, are different.

However, the market situation for electric vehicles can share with you.

Electric cars are divided into: EV/HEV, EV for pure electric vehicles, HEV is a hybrid car. HEV is divided into mild hybrid, severe mixed.

EV, for research and development stage, there is no real joint models, it is said that the shenzhen byd pure electric vehicles: E6, has obtained the approval, but if for selling, wait until the end of 2010, or 2011, and may be even more behind.

At present, the HEV production more, more typical is; TOYOTA PRIUS, which belongs to the mild hybrid, the battery used for nickel metal hydride batteries, Fuel-efficient, about 20-30%. Domestic sales price: 280000.

The Honda civic have HEV version, it is said that in wuhan.

Personal advice: HEV can also be considered, but the unit price is very high, may not reality, so the PRIUS09 years sales in China: 1500 or so.

Can wait and see, the current domestic subsidies in perfecting the new energy vehicles, I expect, at the end of 2010 domestic models may for personal selling, and subsidies.

Thank you very much for your attention to the new energy vehicles.

I am also a focus on new energy vehicles.

2 years, electric vehicle (BEV) refers to an on-board power supply for power, with the motor driven wheel drive, conforming to the requirements of road traffic and safety regulations of the vehicle. Due to the traditional car small impact on the environment, and its prospect is widely, but the technology is not yet mature. Working principle: battery, electric current, power regulator, motor, power transmission system, drive the car (the Road).

Pure electric vehicles, relative to fuel vehicles, the main difference between the (different) lies in the four major components, drive motor, speed controller, power battery, car charger. Relative to the gas station, it is made up of common superfast charging stations. All-electric cars difference depends on the quality of the four parts, the value of high and low also depends on the four components of quality. Pure electric vehicles use also in four parts is directly related to the selection of configuration.

All-electric cars per hour speed, and start the speed depends on the drive motor power and performance, its continuation line mileage depending on the size of vehicle power battery capacity, the weight of the vehicle power battery depends on the choice of power battery such as the lead, zinc, lithium batteries, etc., their volume, weight, than power, specific energy and cycle life are different. Depending on the manufacturer of the vehicle class USES as well as the market definition, market segmentation and positioning.

Byd engineer, said: "byd last longer than the vehicle battery life theory, like shenzhen F3DM in accumulated operating 500000 kilometers, the pure electric range was reduced to 40 km from 50 km, equivalent to 20%. The other byd batteries warranty for life."

Beijing new energy for its products in 2017 to conduct a comprehensive upgrade, the battery quality assurance by the previous 8 years to rise to the current 120000 km, 150000 km. Compared to the ternary lithium battery, Beijing new energy vehicles, iron and aluminum phosphate batteries, ternary lithium battery higher energy density, low temperature performance, higher reliability and longer life, better 2000 times charging and discharging attenuation is less than 10%, a times more than the national standard.

In daily life to slow attenuation of battery tips: 1. Let your car once a month full set; 2. Try to put the power consumption to less than 20%, and recharged; 3. How to charge reasonable collocation, try to use slow filling way to recharge.

In using process, electric cars, battery attenuation is a normal phenomenon. As long as the attenuation degree within the normal range, the consumer is acceptable. In the warranty period if the battery performance attenuation of more than 20%, the manufacturer will free replacement battery monomer. Finally attach some mainstream models of battery warranty period:

Byd, byd new energy car batteries is lifetime warranty, battery 8 years (150000 km).

Teng potential: potential room 400 warranty policy: 8 years, 150000 km for free, and give additional maintenance, basic covers all together teng potential life cycle maintenance, according to electric colts small make up to know, is bound to find a new maintenance policy, but it is still uncertain.

Beijing new energy, new energy automotive since this year petronas listed, commitment to consumer, new EX260 and EU260 models batteries lifetime warranty (private limited operating vehicles), activities are limited to car user before April 2017. After the end of the activity, SanDian system is 8 years, 150000 kilometers, the vehicle warranty is 3 years, 60000 kilometers, and at present, Beijing new energy continues the old car replacement policy.

Geely emgrand: emgrand EV300 core components such as batteries, warranty period for 8 years, 150000 kilometers, there is no change. According to geely holding group, vice President of jin-liang liu said that the taxi market warranty period in the second half of the year is expected to be up to three years, 300000 km from 8 years quality assurance, 500000 km is still in the test plan.

New energy: jianghuai jianghuai new energy vehicles core parts quality assurance period for 8 years, 150000 kilometers, electric parts for 5 years, 100000 kilometers, easy loss components for 3 months, 3000 kilometers, 120000 kilometers vehicle parts for 3 years. In-store sales staff said that there is no charge for warranty period, warranty period after the vulnerable parts maintenance within one hundred yuan commonly.

Chery new energy: chery new energy vehicles vehicle warranty 3 years 120000 km, SanDian system is 8 years, 120000 km. According to chery new energy sources, the usual maintenance cost is controlled in 100 yuan each time.

Know beans: bean and SanDian system for vehicle warranty for 8 years, 120000 km.
