NASA has conducted special research on how to extend battery life. The results of the study show that the more fully charged the battery, the greater the loss. If the lithium battery's power is kept in the middle, the battery life will be longer. This means that you should not charge the lithium battery to 100%, and do not exhaust the lithium battery. The smaller the interval between charging and discharging, the better.
If the capacity of one of the battery cells in the battery pack is lower than the other cells, after a plurality of charging and discharging, the battery cell will eventually enter a deep discharge state, and may even cause the entire battery pack to malfunction. In order to avoid such a situation, a mature electric vehicle will be equipped with a detection device to monitor the working state of each battery unit; some will also set a discharge device to balance the state of charge of the battery unit.
How long does it take to fill the battery?
Different models, different charging equipment, and the time to fully charge the battery vary greatly.
Under normal circumstances, if you use the charging pile or charging wall box specified by the manufacturer, you can fully charge the battery within six to eight hours. However, if you use ordinary household power, the battery can last up to ten hours. This is also the main reason for restricting electric vehicles for intercity travel.
Is the cruising range longer in hot weather?
Hot weather may make the battery's redox reaction more active, but the possibility of reducing the cruising range of the vehicle is greater. In hot weather, most drivers and members use car air conditioning systems, which obviously increases power consumption. In addition, when the vehicle is working in a high temperature environment, the amount of heat generated by the vehicle battery is large, and the coolant circulation is also required to help the battery control the operating temperature.
Will it be out of power quickly in cold weather?
Unlike batteries used in cameras and mobile phones, electric vehicles are equipped with industrial-grade products that have been designed and manufactured to take into account the performance in harsh climates. Lithium-ion batteries are used at low temperatures, and the efficiency of the battery will be significantly reduced, but mature electric vehicle manufacturers have equipped the battery with "air conditioning" - when the weather is cold, the driver can enjoy the heated seat, and the battery can also enjoy the "electric blanket". .
Will the battery be stolen after parking?
Unlike gasoline vehicles, electric vehicles' batteries are often fixed to the chassis part of the vehicle. Professional equipment and tools are required for disassembly. The battery type of the electric car is special, and there is no conventional positive and negative pile head. After the theft, it is not easy to sell, and there is no door to use. It is also boring.
Can an electric car be equipped with an external device?
Electric vehicles can of course be connected to external electrical equipment, cigarette lighters that are carried with the car, flash memory and SD cards that play songs, and the recently popular driving safety recorder. However, the power management of electric vehicles is more strict than that of gasoline vehicles. When the current of the electric equipment exceeds the safety threshold and the remaining power of the vehicle itself is low, the on-board computer will cut off the power supply of the external equipment without mercy.
Will the cable be stolen while charging?
This is really a matter of spelling people. At this stage, people who buy electric cars will have fixed parking spaces, some of them will have fixed parking spaces in the basement, and neighbors and staff who can access electric vehicles. Under such conditions, the charging cable is still missing, and perhaps other reasons should be checked.
Which is better for fast charge and quick change?
From the current results, "charging" has clearly won. Most electric vehicles in recent years have adopted charging technology for electric vehicles. This seems to imply that "changing electricity" has become a past tense.
In several cities such as Hangzhou, electric vehicles that can replace power batteries have been sold. The advantage of “changing electricity†has been very obvious. Replacing the battery can greatly shorten the waiting time for charging. When the meter shows that the vehicle is running low, it can be directly driven to a nearby power station. If there are not many vehicles, the power can be changed in three or five minutes, and the electric vehicle can be "full of blood" on the road. However, infrastructure construction directly restricts the development of “changing electricity†– land resources in large and medium-sized cities are scarce. Building a large-scale power station requires not only multiple land in the central city, but also as far away as possible from residential areas. Text / reporter Wu Hao
Is the battery charging when reversing?
Vehicle movement necessarily requires work, and electric vehicles are still consuming electricity. If it is replaced by a gasoline car, it seems easier to explain that the engine needs to be powered regardless of whether it is driving forward or backward.
UPE plastic,full name UHMWPE (ultra high molecular weight polyethylene) is a kind of thermoplastic engineering plastic with excellent properties of linear structure, with a molecular weight of more than 1.5 million.mainly have ESD UPE SHEET,CONDUCTIVE UPE.
Small density, good wear resistance, self - lubricity, impact resistance, corrosion resistance and so on.
Advantages:
1. Average molecular weight about 5,000,000 to 9,000,000;
2.The best abrasive assistance of all plastics , which 4 times higher than that of nylon 66 or teflon and 6 times higher than that of carbon steel;
3.Extremely high impact stength ,which is twice as high as PC ,5 times as high as ABS,it also retaines high toughness at liquid nitrogen temperature (-196'C);
4.Low friction coefficient ,lubricity is equal to that of Teflon ;
5.The best impact energy absorption value of all plastics ,with very good sound reduction effect ;
6.High chemical stability ,capable of resisting various types of corrosion and organic media within certain temperature and concentration range;
7.Strong adhensive resistance which is only second to Teflon;
8.UHMW-PE Plastic is safe , healthful and non-toxic and be can used in contact with food and drugs ;
9.Low density than any other thermoplastic ;
10.Excellent electrical insulation and static resistance ,good resistance to high energy radiation;
11.Moderate mechanical strength,stiffness and creep-resistant property'
12.Outstanding machining property ,very low water absorption .
Deficiencies:
Compared with other engineering plastics, UHMW-PE Plastic is resistant to heat resistance, stiffness and hardness, but can be improved by means of "filling" and "crosslinking".
From the point ofheat resistance, the melting point of UHMW-PE Plastic is approximately the same (136 ℃) and ordinary polyethylene, but because of its big molecular weight, melt viscosity high, so the processing difficulty is big.
Applications:
Papermaking industry : suction box boards ,scrapper,molding plate ,beating ,gear .
Mining industry : charging barrel ,abrasive and adhensive -resistant back lining for warehouses.
