What is Solar Energy Generation System

Image
Solar power generation system, also known as  solar energy storage system , solar energy is converted to electrical energy through the solar charge controller to power the load, while to the battery pack. Introduction Solar power generation systems, also known as solar power systems, solar energy is converted to electrical energy through the solar charge controller to power the load, while giving the  lifepo4 battery pack ; in the absence of sunlight through the solar charge controller from the battery to the DC load power supply, but also the battery directly to the individual inverter power supply, through a separate inverter is inverted into AC power to the AC load. System Principle Sun light in the semiconductor p-n junction, forming a new hole - electron pairs, under the action of p-n junction of the electric field, holes from the n region to the p region, electrons from the p region to the n region, after turning the circuit form a current. This is the photovoltaic solar

Difference LifePo4 Battery and Ternary Battery

Image
Lithium battery electric car is one of the most common types of batteries, although its inception in 1970, the time is not long, but with a high energy density, long cycle life and other characteristics quickly occupied the vast majority of electric vehicle battery market part of country. Today, in the sale of electric vehicles with lithium batteries mainly have two kinds of  LifePo4 batteries  and ternary lithium. So ternary LifePo4 battery which different but it? Battery power is the core of electric vehicles, pure electric vehicles are the only source of driving energy is directly related to the power performance, battery life of electric vehicles, but also directly related to the safety of electric vehicles. The cost of new energy vehicles constituted, the battery-powered systems accounted for 30-50% of the cost of new energy vehicles. And since the birth of electric vehicles, battery technology has restricted the practical process of electric vehicles. Increase power density, ener

What is Ternary Polymer Lithium Battery

Brief Introduction Terpolymers lithium electrode material is corrected using lithium batteries - Mn lithium nickel cobalt cathode materials, lithium ion battery cathode material there are many, mainly lithium cobalt oxide, lithium manganese, nickel, lithium, ternary material ,  LifePo4 batteries . Currently ternary material batteries instead of lithium cobalt oxide core before the widespread use of laptop batteries widely used in the field of hair. Parameter Nominal Capacity: 1250mAh Standard discharge continuous current: 0.2C Maximum continuous discharge current: 0.5C Discharge: -20 ~ 60 ℃ Size: MAX 9.5 * 35 * 52mm Finished resistance: ≤150mΩ Lead Model: GB wire UL1007 / 24 #, line length 55mm Protection parameters: overcharge protection voltage / per string 4.325 ± 0.025V Over-discharge protection voltage 2.5 ± 0.05V Overcurrent value: 2 ~ 4A Performance In terms of the capacity and safety of the material more balanced, normal cycle performance better than lithium cobalt oxide, pr

Why Sotrage Battery Need BMS (Battery Management System)

Remote meter equipment due to its special working conditions and work requirements of the battery is very high. It requires the battery has a longer continuous power supply capacity, battery life time is often needed to reach a year or even longer.Because of the lithium batteries high voltage, small size, light weight, high energy density, no memory effect, no pollution, low self-discharge, long cycle life, the many advantages of being widely used in remote monitoring long standby instrument. Compared with nickel-metal hydride batteries,  lifepo4 batteries  30%-40% lighter, energy 60% higher than it. However, lithium also has serious flaws, is summarized in the following two aspects: Safety Lithium battery security is poor, when an explosion and other defects. Especially lithium cobalt oxide cathode materials for lithium batteries can not be high-current discharge, poor security. In addition, almost all kinds of lithium battery overcharge or over-discharge can cause irreversible da

Solar Energy Storage Battery Technology Get a Revolutionary Breakthrough

Image
When natural gas, coal, oil and other non-renewable resources, frequent emergency, energy is increasingly becoming a bottleneck for social development, the solar,wind and other renewable resources has become a new driving force for economic development. At the G20 summit, renewable energy issues, environmental issues will become the object of world leaders concerned, and as the organizer of China is more practical action to demonstrate its adherence to the concept of environmental protection,  solar power energy storage  technology also achieve a breakthrough, and further summit environmentally friendly match. Solar energy battery storage in the near future will occupy an important position in the world energy consumption, not only to replace part of conventional energy sources, and will be the subject of the world's energy supply. By 2030, renewable energy in the total energy mix accounted for more than 30%, while the proportion of solar battery storage in the world's tota

Lithium-ion Battery VS LifePo4 Solar Energy Battery Storage

Image
LifePo4 solar energy battery storage, refers to as a cathode material for  LifePo4 batteries . Lithium-ion battery cathode material of lithium cobalt oxide, lithium manganese, nickel, lithium, ternary materials, lifePo4. Wherein the lithium cobalt oxide cathode material is currently used in the vast majority of lithium ion batteries. LifePo4 Solar Energy Battery Storage Eight Advantages Improve safety performance lifePo4 crystals of P-O bond firm, difficult to decompose, even at high temperature or overcharge will not be as lithium cobalt oxide as the structure collapses fever or strong oxidizing substances, it has a good safety profile. There are reports that practice acupuncture or short experiment, we found a small part of the sample combustion phenomenon occurs, but there was one case of bombing, and overcharge used in the experiment far beyond the self-discharge voltage of high voltage charging several times and found that there are still explosions. Nevertheless, the overchar

Dehydration Problem Lithium Battery Cathode Material LifePo4

Dehydration is a  lifepo4 battery pack  materials eternal topic, both positive and negative material production, or electrode production process have to face the problem of dehydration. FePO4 precursor material is both LiFePO4 material, but also can be used alone as the positive electrode material, so the problem of dehydration FePO4 material that we can not avoid the problem. Generally iron phosphate dehydration process is divided into two parts: the first one, mainly to take off some of the material in the free water which is very easy to remove, the temperature is lower. Second, the crystallization of the material off the water, the water molecules with the iron phosphate materials chemically combined manner, it requires a higher activation energy - that is, higher temperatures, complete removal of the water to this part, but the study reaction kinetics of the process is not a lot. Preparation of iron phosphate commonly used ferric sulfate or other soluble ferric iron source, pho
