Dual Power Flow Energy Storage System

Introduction to the Dual Power Flow Energy Storage System
Definitions and Principles
Dual Power Flow Energy Storage System is an energy storage system that can realise the bidirectional glide of energy. Not solely can it shop electrical energy from the grid, renewable electricity technology tools (e.g., photo voltaic panels, wind turbines), etc., however it can additionally be reversely fed lower back to the grid or powered through hundreds when needed. Its core precept is based totally on superior energy electronics and battery administration systems, which allow environment friendly storage and launch of electrical power with the aid of controlling the drift path and magnitude of power.

Main components
Energy storage batteries
Lithium-ion batteries, lead-acid batteries, or glide batteries are generally used. Taking lithium-ion batteries as an example, they are extensively used in bidirectional strength float electricity storage structures due to the fact of their benefits of excessive power density, excessive cost and discharge efficiency, and lengthy cycle life. Different sorts of batteries are appropriate for one of a kind software situations and needs.

Power Conversion System (PCS)
This is a key thing in accomplishing bidirectional electricity flow. It is succesful of changing direct cutting-edge and alternating modern to and from every other, and can exactly manipulate the path and magnitude of the energy flow. When the power storage device is charged, the PCS converts alternating modern to direct modern to cost the battery; When discharged, the PCS converts the battery's direct present day into alternating modern and offers it to the load or grid.

Battery Management System (BMS)
It is accountable for monitoring the repute of the battery, such as voltage, current, temperature, SOC (state of charge) and different parameters to make certain that the battery operates inside a secure working range, forestall overcharge, overdischarge, overheating, etc., and prolong the carrier existence of the battery.

Monitoring and manipulate systems
It is used to screen the running repute of the power storage machine in actual time and coordinate the manipulate of a range of components. Through this system, operators can remotely display the parameters of the power storage gadget and alter the operation approach of the power storage device in accordance to real needs.

Features & Benefits:
Improve power efficiency
It can shop electric powered electricity when the electrical energy consumption is low, launch the electric powered strength at some stage in the top electrical energy consumption, recognize top shaving and valley filling, enhance the normal electricity utilization effectivity of the energy grid, and minimize the electrical energy fee of users.

Enhance grid stability
When the energy grid fluctuates or fails, the bidirectional electricity glide electricity storage gadget can reply quickly, inject or soak up strength into the strength grid, play a function in stabilizing voltage and frequency, and enhance the reliability and steadiness of the electricity grid.

Support renewable strength access
Due to the intermittent and fluctuating traits of renewable power (such as photo voltaic and wind energy), the bidirectional energy glide strength storage machine can keep extra renewable electricity and fill up it when the strength is insufficient, enhance the absorption capability of renewable energy, and promote the large-scale software of renewable energy.

Modular design
It has top scalability, and can flexibly configure electricity storage ability and energy in accordance to real needs, which is appropriate for utility situations of distinct scales.

Lightest and Safest

The lightest and most secure 3600W bi-directional electricity storage electricity supply, there is no one.

Adopting EVE lithium iron phosphate battery, electricity density is greater than 20% greater than peers, the product is secure and reliable.

Bare laptop weight 40KG, dimension 550 * 321 * 464.

Industry Leading Level

PV input support up to 2000W, input range 12V-160V, in the industry leading level.

After waking up the system, 5W standby power consumption, almost the lowest in the industry.

High-power super fast charging

AC output efficiency is very high, the average efficiency of more than 92%, the whole capacity conversion efficiency of more than 85%, the same level of products is almost the industry's best standard

Keep your equipment working

Usually, the battery in the work equipment cannot last for a whole day or more, which requires us to plan the work in advance and prepare a lithium portable power station with sufficient power.

Continuous energy supply

In this off-grid situation, you simply cannot find a source of electricity to charge your work equipment. If this place is far from the power supply place, the round trip will delay a lot of working time, increase costs and reduce work efficiency.

Easy to move

The overall weight of Energipak 3840 is close to 40kg. We use rollers at the bottom of the battery to move it. The hidden telescopic rod design allows you to move it as easily as a suitcase.

Source of power generation

Even if you already have your own lithium portable power station, its power will be exhausted one day under high-intensity and long-term working conditions. Therefore, how to recharge portable power supplies is also one of the headaches, because mains power is not always guaranteed.
