LifePo4 Storage Battery For Portable Solar Power Generator

Lithium-iron battery solar powered portable generator system can be used as a variety of electric power and stability of the buffer between the needs of the power can be increased as wind, solar and other unstable power generating capacity. Wind power generation system due to changes in wind speed and cause the output power of the oscillation, and portable solar power generator system can be fast response speed, almost equal to the charge-discharge cycle characteristics provide stability and reactive power compensation for the fan output. At the same time, the energy storage system can adjust the voltage and off-grid power system frequency control system.



Control System

Lithium-Iron battery solar power portable generator system consists of a programmable logic controller (PLC) and human machine interface (HMI) control. One of the key functions of the PLC system is to control the energy storage system charging time and rate. For example: PLC electricity prices may receive real time data, and based on the maximum allowable electricity demand, as well as the state of charge Compare prices peak / off-peak time, decide how quickly to re-charge the lifePo4 batteries system. This decision is dynamic and can be optimized according to specific circumstances. Through standardized communication input control signal and power supply, which is integrated with the rest of the portable solar power generator system. It can be accessed through a dial-up or Internet. It has multiple layers of defense to limit access to its various functions, and provides customized reporting and alarm functions for remote monitoring.

Power Conversion System (PCS)

Function power conversion system is the lifePo4 batteries charge and discharge, and to provide an improved quality of power supply voltage and frequency control support for the local grid. It can have a complex, fast acting, multi-quadrant, the dynamic controller (DSP), with a dedicated control algorithms to the entire range of switching the output device, i.e., the cycle from absorbing full power. Reactive power demand as well as any combination of active and reactive power, it can work properly.

Lithium iron Stack

The stack is made of many cells. Iron lithium battery portable solar power generator system to economically store and provide large-scale power on demand, is the main mode of fixation. It is a long-life, low maintenance, efficient technology to support extensions stepless power and storage capacity. Energy storage system for renewable energy providers, power companies and end-users are particularly effective.

Deferred grid fixed investment, as well as load shifting applications. Solar power portable generator system can also serve as a communication station and substation to provide backup power to be applied.  lifepo4 48v energy storage system for environment-friendly, in all energy storage technologies for minimal ecological impact, but not to lead or cadmium and other elements of the main reactants.

At the same time, the energy storage system can adjust the voltage and off-grid power system frequency control system.

Power Supply in Remote Areas

In the sparsely populated remote areas, such as islands, diesel generators often as a single source of energy. Diesel generators are often due to changes in load and in a non-rated power, which makes fuel-efficient reduced by about 30%.

Off-grid solar power supply system configuration storage system can effectively reduce diesel consumption, operation and maintenance costs, greenhouse gas emissions and extend the life of diesel engines.

Wind power and photovoltaic power generation accounted for the total proportion of diesel power increasing, while the proportion reached 30% of the time, it brings instability will directly reduce the reliability of the local power grid, should be more limited increase in renewable energy electricity. However, by configuring the portable solar power generator system, the ratio may be 100%, and the project payback period be shortened to three years. With rising fuel prices, the economy will be more significant.

Research And Development New Battery Technology

In addition, energy storage research also has multiple problems, such as foam cells, flow batteries to a variety of chemical materials, no one knows which technology will attract the most funds and research heat.

Lux Research reports that the energy storage investment of more than 40 billion US dollars, such as solar power generator and wind power, the development of next-generation batteries, non-lithium-ion battery startups in the past eight years, an average of only 4 million funds, Tesla investment in lithium-ion battery factory Gigafactory invested 5 billion US dollars .


R & D new battery material threshold is very high, just to build a small production line to study the details into production, it is necessary to 500 million US dollars, car manufacturers may also take several years to test the new battery system before deciding whether to purchase, if Your company has only $ 5 million in capital a year, making it hard to invest $ 500 million in manufacturing.

Leyden Energy, A123 Systems, Seeo, Sakti3 are not looking for the end because of the factors such as production, price and other factors that investors will not be able to achieve, even if the new battery manufacturers commercialize new technology, and will face the problem of increasing production and looking for buyers.

The world's three major battery manufacturers, Samsung, LG, Panasonic on the new chemistry and significantly change the battery technology are not too interested in, they would rather gradual improvement in the existing technology. The battery technology can improve device application, lighten the device weight, such as when people take solar powered portable generator to travel.

Although the first lithium-ion battery as early as the 1970s to come out, but now technology has been getting better and better, which is innovative battery technology, the most reluctant to mention, and they face the biggest problem.

No longer blew! Prevent Lithium Battery Explosion Method!

( 48V) Lithium batteries are flammable devices, mobile phones, scooters and other built-in lithium device, if used improperly, there is always the time of explosion. We have reproduced in movie, show scooter lithium blast.

Do lithium produced in the manufacturing process itself is also a problem can not be ignored, because the manufacturing process was defective, it is easy to leave fragments of metal dust, copper and aluminum foil between the positive and negative should be insulated from these scrap battery overheated, will be like the dumplings in boiling water to do the same random thermal motion in the electrolyte, if prolonged exercise, these particles happen to be close to the lifepo4 battery positive and negative poles in the middle of the diaphragm can easily cause a short circuit inside, and inside the battery the electrolyte is a flammable liquid, a spark caused by a short circuit in a confined environment can easily lead to electrolyte battery ignition internal combustion and explosion. Is there a lithium battery to prevent prevent blew? American universities have studied the new technology successfully. 

Stanford University scientists have developed a new lithium battery, and claim to have mechanism to prevent the explosion. Traditional lithium-ion batteries will be between the electrodes with liquid or gel electrolyte containing ions, these electrolytes because of a short circuit, overcharge and other factors continue to generate heat, once the temperature is too high, for example, more than 150 degrees, the electrolyte will fire and explosion, and this prevents blew lithium battery prevents this from happening, the principle is automatically powered off before the battery overheating, so that the battery is no longer a chemical action ordered temperature decreases, when the temperature is reduced to a certain level when the battery quickly restart. This batteries can be used in solar powered portable generator.


However, they are not flame retardants and the like so that the battery can not use the material, but turned to nanotechnology, nanoscale nickel particle surface plus a layer of graphene, and embedded in a flexible polyethylene film, and the film will connect the two poles . The film will be stretched when heated, separated from the conductive nickel particles, will cause power outages effect, then the film cools, it will reconnect the power supply of the nickel particles.
