In winter, the  solar power batteries  should take the following conservation measures: Greenhouse overhead storage batteries when not in the house to save more than 0 ℃, should not be placed directly on the ground. Before storing the first external battery clean, add enough liquid electrolyte, adequate electricity, tighten the plug. After a supplementary charge every month, once every two weeks to check the electrolyte level, and refresh immediately insufficient. Thus, the battery can ensure safe winter. Progress liquid volume ratio of water and sulfuric acid electrolyte composition, the higher the content of sulfuric acid in the electrolyte, the electrolyte specific gravity higher, the lower the freezing temperature of the electrolyte. To this end, the country may be to select the appropriate proportion of the electrolyte according to the local winter minimum temperature, to prevent the electrolyte from freezing. Enough electricity to keep the state during the winter, when the batter

Battery Lose Effectiveness Modes Since the plate type, production conditions, there are differences in usage, and ultimately lead to the battery '> reasons for battery failure is also different, back satisfied them, there are several  Lose Effectiveness  modes:  1.Corrosion deformation of the positive electrode plate board gate Alloy currently used on the production of three types of traditional lead-antimony alloy, antimony or ultra-low antimony alloy, lead-calcium. The three cast alloy grid, the battery charging process will be oxidized to lead sulfate and lead dioxide, leading to the loss of the role of supporting the active material of the battery failure; after corrosion due to the formation of lead dioxide layer, of lead alloy to produce stress, the linear grid grow up deformed, and finally the destruction of the whole plate, the active material and grid off poor contact or short circuit at the bus. And these batteries can be used in  solar powered portable

The lithium-ion battery electrolyte material different from the lithium-ion battery is divided into liquid lithium-ion battery (Liquified Lithium-Ion Battery, referred to as LIB) and lithium-ion polymer battery (Polymer Lithium-Ion Battery, referred to as the PLB) with lithium or plastic ion battery (Plastic Lithium ion batteries, referred to as the PLB). Anode and cathode materials used in lithium-ion polymer battery with liquid lithium-ion is the same, divided into cathode material of lithium cobalt oxide, lithium manganese oxide,  LifePo4 batteries  ternary materials and materials, graphite is extremely negative, the battery works basically consistent. The main difference lies in the different electrolytes, liquid lithium-ion battery using a liquid electrolyte, lithium-ion polymer battery Zeyi solid polymer electrolyte to replace, such polymers can be "dry state", it can be "colloidal" currently most using a polymer gel electrolyte. Classification Solid: The

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

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

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

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
