Solar Power Generation Systems Classification

Image
Solar power generation into off-grid power systems and grid systems: Off-grid power systems. Mainly consists of solar modules, controller, battery composition, to an AC load, also need to configure AC inverter. DC power generation system is generated through solar modules and grid-connected inverter converts AC power into the electricity grid in line with the requirements of direct access to the public grid after this. And power generation systems have centralized large-scale power plants are generally national grid station, the main feature is the power can be directly delivered to the grid by grid power to the unified deployment of the user. But this power plant investment, long construction period, large area, the development of a relatively large degree of difficulty. The small and decentralized power generation systems, especially BIPV power system, due to the small investment, quick construction, small footprint, large policy support, etc., is the grid of the mainstream.

Why Lithium Polymer Battery So Popular

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 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 solid poly

What is Solar Energy Generation System

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 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 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 cell works. A so

Ternary Lithium Battery Advantages and Disadvantages

Image
Advantage Since early 2014, all aspects of lithium ternary material constantly modified, increasing the number of cycles, the current appropriate increase in the cost of already more than 1500 times, and the safety performance of lithium ternary material is constantly improving, more and more close to LifePo4. The past two years the emerging new nickel-cobalt-aluminum ternary materials, although in the battery manufacturing process on the environment are higher, but the stability and security further enhanced, as recognized by many battery factory, trial production. High voltage platform. Voltage platform is an important indicator of the battery energy density, determines the basic performance and cost of the battery, so the choice of battery materials, has important significance. Voltage platform, the greater capacity than certainly the same size, weight, even when the battery pack is the same, a relatively high voltage platform mileage lithium ternary material farther. Ternary

Compare Ternary and LifePo4 Battery

In recent years, new energy vehicles are booming, domestic battery industry to promote the explosive growth of the core power battery electric vehicles, electric vehicles using  LifePo4 batteries  are ternary lithium battery, LifePo4 mainly discussed below ternary lithium battery advantages and disadvantages. At present, new energy vehicles, the main use of LifePo4 batteries, but limited theoretical energy density LifePo4 batteries, LifePo4 monomer energy density of 120Wh / kg, after the group energy density of 80Wh / kg, So now companies are actively developing higher energy density lithium phosphate material ferromanganese new power lithium battery. The three yuan higher battery energy density, ternary lithium battery energy density of the monomer 180Wh / kg, after a group of 110Wh / kg, corresponding market have obvious advantages. Therefore, in terms of energy density, three better than the LifePo4 lithium battery. Speaking from the safety of LifePo4 batteries has more advant

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 and lithium three yuan. 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, energy densit
