Currently, internal research and development of electric vehicles are mainly used in lithium-ion batteries, but aside from battery production BYD, the majority of mileage endurance and speed are very limited, short duration, while security must be improved, currently, many failure rate of the Laptop battery is greater than one millionth of the level of security, burning vehicles and problems arise. These problems make electric cars the field of large-scale participation of private cars, there are many obstacles, which are common problems encountered in the world by other manufacturers.
Beijing Institute of Technology, an electric car expert said, a very important reason is that production of the 40Y6797 battery has not yet industrialized, there is a lot of batteries or a hand, small production, and therefore difficult to ensure the quality and unity. At the same time, users still have a lot of battery to use inappropriate need for more guidance.
Institute of Electrical Engineering Chinese Academy of Sciences, one expert said that the life of the current mileage is not enough battery electric cars at low speed using the scope is limited. At the same time, although some argue that the majority of electric vehicles can use the family 220V load voltage, but the actual operating point of view, usually filled with a Dell Latitude X1 battery lasts 10 hours or so, so long cooldown is neither convenient nor practical to use for this building Fast Chargers needed.
Charging station is difficult to achieve large-scale construction of
Improved facilities at the loading station of the electric vehicle is the key to the promotion scale. National Grid is currently pricing of infrastructure has accelerated the pace, Zhengzhou and Wuhan, a small number of charging stations and other places have been commissioned, but because of the high cost of station construction load, uniform standards for Jianzhan missing, investors are not clear and the relevant government departments to coordinate the hp F3172A battery large-scale construction makes the charging station in the short term is unrealistic.
“In fact, the current total capacity of electricity generation to meet domestic electricity demand electric vehicles, shortages of electricity does not exist, the key is that the feeding stations many The lack of capacity of storage, a large number of peaks and valleys are the loss of electricity. In addition, coal remains the major current sources of national electricity production, this sony VGP-BPS2 battery is not conducive to environmental protection, the State must increase investment in wind energy and nuclear power. “Beijing University of Technology, an electric car expert said.
In addition, construction of facilities so as to take charge of standards that must be resolved. China Lithium-standard system battery power ion drafting group of a person in charge, how to ensure that the construction of fast-charging toshiba PA3399U-2BRS battery charging station is key to ensuring the charging station can buses, taxis and private cars are able to apply, just as importantly, the technical level, there are some difficulties.
F3DM electricity as fuel costs ordinary vehicle 1 / 6
BYD dual-mode electric vehicles can be buttons F3DM in pure electric (EV) and hybrid (HEV) to switch between two modes. Holder of the battery life of iron in pure electric mode to achieve mileage of 100 kilometers with a total mileage of more than 600,000 miles lifetime of the vehicle to a maximum target of 10 years. Regarding power, BYD DM electric vehicle equipped with dual-mode power up 50kW / L power hair aluminum engine with 75kW, the apple A1061 battery power output reaches 125kW. In carrying load, BYD dual-mode electric vehicle can reach the office of professional equipment fast 10 minutes filled with 50% of the ordinary household socket can be used while charging, 7 hours can be fully charged.
Currently, the two official offers F3DM mode electric vehicles from 14.98 million yuan, according to a state of pure electric load, F3DM dual-mode electric car 100 kilometers of pure electric consumption is 16 degrees (data advertising works), according to Peking current 0.48 yuan / kWh electricity and travel 20,000 kilometers per year calculated at 1536 yuan per year for electricity.
Ordinary F3 1.6 Sheng automatic version of the official bid 798 million, more than double F3DM vehicle’s electrical yuan less than 70 miles. Its Aspire 3000 battery fuel consumption is about 8 liters per 100 kilometers, according to an annual mileage of 20,000 kilometers and the No. 93 Beijing oil 5.56 yuan per liter, to calculate the cost of fuel a year to 8896 yuan, F3DM for nearly six times the dual-mode vehicles. About the use of new and more than a year and a half, two-vehicle electric car can recover more than the cost.
Prius 8 years to recoup the cost of
FAW Toyota Prius production hybrid, using battery-powered engine, do not need to recharge. Its effective use in the process of around 100 km fuel consumption average of about 5 liters displacement of 1.5 liters, but with the HSTNN-LB31 battery, power output roughly equivalent to conventional gasoline 2.0 The dynamic performance model.
Under an annual mileage of 20,000 kilometers and Beijing, 97 to calculate the price of oil, the Prius oil per year for the sum of 5920 yuan, while the low standard with the Prius is currently the official target price is 259, 8 miles yuan.
Link to a substantial 2.0-liter model powered by a fuel consumption of 12 liters integrated by calculating hundreds of kilometers, the annual fee required for oil to 12,000 yuan, but the market is the 2.0L integrate models, with a unit for the Toyota Camry 200G Deluxe Edition (non-minimum distribution) price of only 209.8 thousand yuan.
In other words, the Prius 6080 yuan per year savings in fuel costs, but the car that the Camry is about the cost has increased by 5 million euros, which was part of the cost of an extra car in the car after more than eight years by the cost savings to recover the oil.
Lifan 320 electricity bill of about 1536 yuan per year
Lifan 320 electric vehicles (EV) is motor vehicle Lifan energy of a new prime.
Lifan 320 (EV) on a single charge life mileage will reach 150 miles high, the road conditions are also integrated over 100 km. 0-50 km / hour h in 6 seconds or less, even with a 100 km / h maximum speed drive 30 minutes later, the speed still at 75 km / hour or more.
The distance of the unit energy consumption was about 0.16 kWh per mile, according to Peking current 0.48 yuan / kWh of electricity and traveling 20,000 kilometers per year calculated at 1536 yuan per year for electricity .
Greater endurance Chery S18 150 km
Currently, Chery S18 electric vehicles has been out of the factory, but not yet recorded, according to published by manufacturers of parameters, its speed can reach 120 km / h, a rechargeable Dell GK479 battery life can reach 120 km Mileage -150 km.
Chery S18 vehicle electric vehicles in the S18 platform, developed on a high-speed pure electric cars may be used for 220V civil charge, charging time is typically 4-6 hours, and also be used for fast charging, a half-hour rechargeable battery 80%.
