Raising the battery's energy density (capacity-type batteries only) is the top priority for designing batteries.
The capacity is not enough, the unit price is lower, the cycle is better, and the safety is even higher. The batteries that are made may be unattractive. So how can we increase the energy density of the battery? It can mainly be considered in several ways:
A few days ago, some media reported that the 10-minute fast charging technology developed by the team of Wang Chaoyang of the Pennsylvania State University in the United States has overcome the key problems of rapid charging and battery life of lithium batteries.
It is reported that the U.S. Department of New Energy has announced plans to support the use of ultra-high-speed charging for electric vehicle batteries with US$19 million. Wang Chaoyang’s team’s technology won this plan and was officially adopted by the U.S. Department of New Energy. The goal is to reduce the cost of the battery to less than $100 per kilowatt-hour before 2028, increase the driving range to more than 480 kilometers, and reduce battery charging time to less than 15 minutes.
The definition of current transformer
Current transformer principle is based on the principle of electromagnetic induction. Current transformers consist of closed cores and windings. It has a small number of turns on the side of the primary winding, which is connected to the line where current is to be measured. The number of turns on the secondary side is relatively large. It is connected in series with the measuring instrument and the protection circuit.
EPDM belongs to one kind of ethylene-propylene rubber, which make it good performance in ozone resistance, and high-temperature resistance. EPDM rubber products are widely used in auto industry, and electronics industry.
The accumulation of residue of plaster and other materials can affect the scaffolding mainly in two parts: safety and cost. When they become hard, not only adhere very stably, but they can also be very sharp. Moreover, the function of individual parts of the aluminum scaffolding may be affected; the component may not be compatible to each other, and leading to not so firm structure that might bring in safety risk.
As a new energy vehicles, low-speed electric vehicles has been increased rapidly ,such as city-car,tuck tuck.
Traditionally these vehicles are powered by lead acid batteries, Bulky and heavy, lead acid batteries are a limiting factor in vehicle design.
When we manufacture high frequency transformers, we often find that there is some noise, squeak, buzz and other bad noise from transformers. According to our production experience, we summed up following several reasons, hope to help eliminate noise from transformers.
一. Magnetic materials
With the continuous development of technology, now all countries attach great importance to environmental issues. So in recent years, wind energy, solar energy, water energy and others new energy develops rapidly. Therefore, energy company attemp to develop their own product to meet the marketing requirements. KOK POWER-regarding innovation as the main potentiality.we now degisn the new lithium batteries applicable for solar street light. If you are contracting projects from government,factory, you may need the high quality batteries with smart technology and all-round services
Compared with other solar light batteries, KOK POWER lithium Led Street Batteries are:
It is generally accepted in the industry that the immediate term objective of lithium battery technology is to achieve 300wh / kg through a high-nickel NMC cathode and a silicon carbon anode. The medium-term (2025) target is based on a lithium-rich manganese-based / high capacity Si-C anode, to achieve 400wh / kg; forward is the development of lithium sulfur, lithium air battery, to achieve the specific energy than 500wh / kg.
With the increasing reliance on electronic products, the market share electronic components in domestic and foreign markets gradually increased, followed by the demand for various types of industrial electromagnetic components are also increasing. Whether using transformers, inductors or a variety of solenoids, the need to constantly innovate high-quality magnetic components in order to ensure reliable quality and long service life of electronic and industrial systems. Among them, high-frequency transformers as a kind of electromagnetic components are slowly affecting the development of the electronics industry.
