Smart Bi-directional Power Supply

Smart Bi-directional Power Supply is an intelligent bidirectional power supply, which mainly includes the following aspects:

Realize two-way flow of energy: The intelligent two-way power supply can realize the forward output and reverse absorption of DC power at the same time, that is, it has power mode and load mode. In power mode, it can provide power to the load; In load mode, the power at the load end can be recovered and fed back to the grid or other energy storage devices, becoming a key bridge connecting energy production, storage and consumption.
High-efficiency energy conversion: Using advanced PWM (pulse width modulation) technology, the intelligent bidirectional power supply can achieve an energy conversion efficiency of more than 95%, greatly reducing the energy loss in the conversion process, in line with the environmental protection trend of energy conservation and emission reduction.
Flexible bidirectional controllability: It can freely switch between power supply and load mode according to actual needs, providing great flexibility for electric vehicle fast charging, battery energy storage systems, solar photovoltaic grid connection and other fields. For example, in the electric vehicle fast charging station, it can not only provide high-power DC fast charging services for electric vehicles, but also serve as an energy storage device for reverse charging when the grid load is low, balance the grid load, and improve energy efficiency.
Intelligent management and monitoring: Integrating advanced communication interfaces and intelligent control algorithms, the intelligent bidirectional power supply can realize remote monitoring, fault diagnosis and automatic adjustment, which greatly improves the operation and maintenance efficiency and safety of the system. Users can remotely control the working status of the power supply through the network, monitor voltage, current and other parameters in real time, and diagnose and repair in time when faults occur.
Simulate complex power environment: Intelligent bidirectional power supply is an indispensable experimental equipment in scientific research and teaching activities in power electronics, new energy technology and other related fields. It can simulate a variety of complex power environments, help researchers deeply understand the principles of power conversion and control, and promote the innovation and development of related technologies.
Support a variety of battery types and charging modes: Built-in a variety of battery charging algorithms, support lead-acid batteries, lithium batteries, lithium iron phosphate batteries, supercapacitors, etc. as energy backup units, and support CC/CV/CP and other battery charging and discharging modes, which can meet the charging and discharging needs of different types of batteries.
Optimize system performance and size: The power sharing function on the input side of the intelligent bidirectional power supply ensures that the upstream AC/DC power supply does not have to be too large, but the input power is kept constant and distributed to the load and charger accordingly, and more energy flows into the charging process when the output is low, and the battery and input can participate in the load supply at the same time when the load is heavy, so as to optimize the system size and performance.

Smart Bi-directional Power Supply is a new generation of energy management equipment that integrates power electronics technology and intelligent control algorithms, and its advantages are not only reflected in the efficient conversion ability of traditional bidirectional power supply, but also realize the precision of energy management, the flexibility of system interaction and the convenience of operation and maintenance through intelligent upgrading. The following is a multi-dimensional analysis of its core advantages:

Lightest and Safest

The lightest and safest 3600W bi-directional energy storage power supply, there is no one.

Adopting EVE lithium iron phosphate battery, energy density is more than 20% higher than peers, the product is safe and reliable.

Bare machine weight 40KG, size 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.

Advanced Technology, Unmatched Performance

1. Intelligent control and energy management: the central brain of dynamic optimization
1. Adaptive energy dispatch algorithm
Through built-in AI models and machine learning algorithms, the intelligent bidirectional power supply analyzes photovoltaic power generation, battery SOC (state of charge), load demand, and grid electricity price signals in real time, and dynamically adjusts energy flow. For example:

PV priority strategy: when the sunlight is sufficient, the photovoltaic power is directly supplied to the load, and the remaining power is stored in the battery;
Peak-to-valley arbitrage mode: According to the time-of-use electricity price data, it automatically takes electricity from the grid for energy storage during the trough hours (such as late at night) of the power grid, and releases battery power during peak hours (such as daytime) to reduce the cost of power purchase.
Load prediction function: By learning historical power consumption data, predict the load curve in the next 24 hours, optimize the energy storage configuration in advance, and avoid insufficient or excess power.
2. Multi-mode flexible switching
It supports multiple working modes such as "grid-connected priority", "energy storage priority" and "off-grid independence", and users can switch with one click through the local interface or mobile APP to adapt to the needs of different scenarios:

Industrial and commercial scenarios: Automatically switch to "energy storage photovoltaic" power supply during peak power consumption hours to reduce the power purchase cost of the power grid;
Off-grid scenario: Automatically maintains a closed-loop of "PV-Battery-Load" to ensure stable power supply in remote areas.
3. Virtual Synchronizer (VSG) technology
Some high-end models can simulate the characteristics of synchronous generators to provide voltage and frequency support for the power grid. For example, in a distribution network with a high proportion of PV access, the intelligent bidirectional power supply suppresses grid frequency fluctuations through virtual inertia response (<10ms) to improve grid stability.
2. High-efficiency conversion and low-loss design
1. Ultra-high conversion efficiency
Using new power devices such as SiC MOSFET/IGBT and three-level topology, the AC/DC bidirectional conversion efficiency can reach 96%-99%. For example, the IPDC2000 Series bidirectional DC power supplies use four-quadrant SVPWM technology to increase industry-leading AC-DC conversion efficiency while reducing harmonic distortion to less than 3%.
2. Light load and heavy load are highly efficient
High efficiency from 20% to 100% load:

The efficiency is still above 95% at light loads (e.g., low-power loads at night), far exceeding 85% of traditional equipment.
Intelligent current sharing control ensures a < 1% efficiency loss for multi-module parallel operation under heavy loads (e.g., industrial and commercial energy storage systems).
3. Dynamic response speed
The millisecond-level mode switching capability (e.g., only < 10ms from grid-connected mode to off-grid mode) can quickly respond to PV output fluctuations or grid conditions
