What is the trade-off between range and safety of Li-ion battery packs? The safety and range of power lithium battery packs is an important issue in new energy vehicles. For most consumers, the improvement of range can well reduce or even eliminate "mileage anxiety", but the accompanying safety issues are also worthy of consumers' consideration and attention.
What is the trade-off between range and safety of the power lithium battery pack?
As we all know, when consumers buy electric cars, range is one of the very important factors, various car companies to meet the needs of consumers, and constantly find ways to increase the range of the car, improve the battery energy density, so the ternary lithium battery high nickel trend is obvious, accompanied by the safety of the power battery.
In recent years, in the new energy vehicle subsidy policy, the power lithium battery pack energy density year by year record high, the new energy vehicle range also continue to improve. However, the electric vehicles that are gradually driving out of the shadow of mileage anxiety seem to have fallen into the dilemma of safety anxiety again. What is the trade-off between range and safety? In fact, only safety without long range, or only long range without safety, the new energy vehicle industry can not be healthy, long-term development. The only way for the industry to grow and develop is to seek to improve both together.
The safety anxiety of new energy vehicles has become the first anxiety, the safety of the power lithium battery pack is the first to bear the brunt, only safe products have the application of the market, for new energy vehicles, safety issues can not be solely blamed on the battery, the need for each link of the system safety design. The focus of attention on power batteries is still focused on safety, range, power, cost, charging convenience, service life, etc., of which, safety is still the most basic and most important requirement.
To improve the safety of power lithium battery pack, we should pay attention to the safety from the battery, cell material to the module, the design of the whole battery pack system, battery management and other aspects.
Power battery quality affects the safety and range of electric vehicles, especially safety issues, should be prevention-oriented, to start with the design of the product, especially in the case of increasing the specific energy of the battery, the more we should focus on safety issues. At the same time, with the expansion of power battery production capacity, China's new energy vehicle power battery industry product differentiation is growing, which will undoubtedly set off a new round of industrial restructuring boom.
Can the range and safety of power lithium battery pack coexist?
In fact, it is possible, but to think deeper, the range is strong, there is always a time when there is no power, it is more important to start solving the problem of charging facilities. However, in some coastal areas of China's megacities, the population density is large, want to improve the charging facilities in these areas is not easy, so the car and electricity is a good way to separate.
Back to the issue of electric vehicle range, the blind pursuit of range is not desirable, but also can not keep the vehicle's range in the initial one or two hundred kilometers. Range needs to be gradually improved under the premise of maintaining the safety of the power lithium battery pack, with gradually improved charging facilities, which can meet to the needs of consumer travel.
Experts say that from the range and efficiency, ternary lithium battery pack is a better choice at this stage, but of course, safety is still its shortcomings. In terms of stability, lithium manganate batteries are undoubtedly more prominent, with good safety under the premise that all indicators are very average. Finally, experts say that the future of new energy batteries is likely to be a situation where hydrogen fuel cells and lithium power batteries coexist.
Summary: The performance of the power battery is not only an indicator of specific energy density, but also the specific power density, safety, consistency, cycle life and other factors of the power battery.
