Lithium iron phosphate batterySelf-discharge discharges to 3% in one month and can be restored to 99%. The lithium iron phosphate battery self-discharges at a rate of 3% per month and can recover up to 99%. Self-discharge is approximately 5% in three months and can be restored to 98%. A self-discharge of around 8% can reach 96% in six months. Self-discharge is approximately 15% in one year and can be restored to 95%. After three years of self-discharge, about 40% can be restored to 89%.
Self-discharge characteristics and precautions of lithium iron phosphate batteries
Do not intentionally discharge when using lithium batteries when DC reminds you that the battery should do it. be charged, if the battery level flashes, it is time to remove the battery and charge it. The charging process must be carried out strictly according to standards. You can remove the batterye once it is fully charged. There is no need to charge it for several hours, even if it is a new battery. Proper use of batteries is the best maintenance of lithium batteries.
What are the maximum and general discharge operating current, charging current and operating voltage of a lithium iron phosphate battery?
Are new energy vehicles suitable for driving in the north?
p>Are new energy vehicles suitable for driving in the north? In fact, this question can be simplified as follows: Are new energy vehicle batteries suitable for use in the North in winter?
At present, new energy vehicles mainly include hydrogen energy, and electric vehicles emit no emissions, while electric vehicles emit a small amount of emissions. This canut be different from what everyone knows, because 72.8% of shows. electrical energy comes from thermal energy. Regarding thermal energy, 94% is coal thermal energy and 2% is gas thermal energy. Therefore, electric vehicles emit emissions every time they are charged.
New energy vehicles are also divided into different types of hybrids, but I will mainly talk about pure electric vehicles, because your question probably does not refer to plug-in hybrids or range extender hybrids .
Let's get to the heart of the matter: electric vehicles in the northern region of China mainly need to consider the problem of battery loss caused by cold winter, which it It is BYD's lithium iron phosphate battery or CATL's ternary lithium battery. battery, although on an international scaleale, they are all battery companies with advanced technologies, but there will be different degrees of power loss at low temperatures. However, the northern region has a large area if it is Shandong, Henan, Beijing, Tianjin, Northern Jiangsu, Liaoning, Liaodong Peninsula and Southern Hebei In these regions, you can buy vehicles electric with a range of more than 400 kilometers, because the winter in these regions is short and the low temperature is certainly not too cold. it is not a problem for a 400-kilometer tram to travel 270-280 kilometers in the coldest winter.
New energy vehicles are a major trend. Technology advances and facilities improve. Even if you buy a gasoline vehicle now, you can upgrade to a purely electric vehicle next time.
In areas such as Inner Mongolia, Heilongjiang, northernd of Gansu, Jilin and Xinjiang, low temperatures in winter can reach minus 30 degrees, or even minus 40 to 50 degrees. tram, and it is likely that it will only last less than 400 kilometers to 200 kilometers, or even less
<.p>1. The working current of lithium iron phosphate battery is generally 1C, the maximum is 15C.
2. Charging current is the same as operating current, generally 1C, the maximum is 15C.
3. The general operating voltage of standard lithium iron phosphate batteries is 3.2V; the maximum operating voltage is 3.65V.
Lithium iron phosphate:
Lithium iron phosphate electrode material is mainly used in various lithium-ion batteries. Since the Japanese NTT first revealed the olivine structure lithium battery cathode material of AyMPO4 (A is an alkali metal, M is a combination ofCoFe: LiFeCoPO4) in 1996, John B. Goodenough of Texas State University in the United States in 1997 and others. research groups also subsequently reported the reversible transfer and desorption of lithium characteristics from LiFePO4.
The United States and Japan coincidentally published the structure of olivine (LiMPO4), which attracted great attention to this material and caused extensive research and rapid development. Compared with traditional lithium-ion secondary battery cathode materials, LiMn2O4 spinel structure and LiCoO2 layered structure, LiMPO4 has wider sources of raw materials, is cheaper and has no environmental pollution.
Lithium iron phosphate battery:
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium-ion batteries includemainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material currently used in most lithium-ion batteries.
