The “modular building block” of commercial and industrial energy storage: the DGPI-SE-002 cabinet-type energy storage battery.
time：2026-08-14
In the deep water area of energy transformation, industrial and commercial energy storage is moving from "demonstration pilot" to "scale application". Factories, shopping malls, data centers, charging stations-these large consumers are facing multiple demands of peak-valley electricity price difference, electricity demand, photovoltaic consumption and standby power supply. The key to meet these demands is a set of energy storage system that can operate independently and expand flexibly. The DGPI-SE-002 cabinet-type energy storage battery launched by Juneng new energy is a modular building block tailored for this distributed energy storage scenario. It is in the industrial form of standard cabinets, the deployment logic of industrial and commercial energy storage is redefined.
I. Standard cabinet form: from "custom project" to "plug and play"
traditional industrial and commercial energy storage systems are mostly customized for projects. From cell selection to system integration, each project is a "from scratch" project. DGPI-SE-002 adopted standard 19-inch cabinet size(W483mm × D560mm × H220mm), the energy storage battery is converted from "engineering project" to "standard product".
Width of 483mm it is an international standard for 19-inch cabinets, which means that DGPI-SE-002 can be directly embedded into standard cabinet arrays in data centers, power distribution rooms, and equipment rooms, without the need to customize supports or transform space. Depth of 560mm adapt to the depth specification of mainstream cabinets, leaving heat dissipation and maintenance channels before and after. Height of 220mm it is about 5U cabinet unit. A single battery pack occupies one floor of the standard cabinet, and multiple layers can be stacked to build a large-capacity system.
88kg weight after ergonomics optimization, two O & M personnel can cooperate in handling and installation, and cooperate with cabinet guide rail to realize sliding into place. This weight level is "lightweight" in the same capacity energy storage battery, which reduces the labor cost of transportation and installation.
Stackable cabinet use it is the core design concept of DGPI-SE-002. A single battery pack runs independently, and multiple battery pack are vertically stacked in a standard cabinet. The capacity is linearly expanded by connecting internal buses in parallel. This "building block" architecture enables the planning of energy storage system to change from "one-time large investment" to "on-demand phased construction"-1-2 sets are invested at the initial stage to meet the basic needs, and additional units are added at any time after the business grows, protect initial investment.
Second, 8 series expansion: flexible transition from "kWh" to "MWh"
the most unique technical feature of DGPI-SE-002 is its up to 8 sets can be used in series. The scalability.
Series expansion means voltage superposition and capacity multiplication. Take a single 48V/100Ah(4.8kWh) specification as an example. Two sets are connected to 96V/100Ah(9.6kWh) and four sets are connected to 192v/100Ah(19.2kWh), the 8 units are connected in series to 384v/100Ah(38.4kWh). This expansion covers the entire scenario requirements from small industrial and commercial energy storage of dozens of kWh to medium energy storage power stations of hundreds of kWh.
The advantage of serial expansion lies in system simplification. Traditional parallel expansion requires complex current sharing design and redundant protection, while series expansion has consistent current and simple management. BMS, which gathers new energy sources, optimizes the series architecture, automatically identifies the number of series Connections, dynamically adjusts charging and discharging parameters, and ensures that battery pack of the voltage, current, and temperature of each station are balanced.
Size can be customized as needed it is a flexible service for gathering energy and new energy. Customized solutions of non-standard sizes can be provided for specific Cabinet heights or installation spaces. For specific voltage platforms (such as 384v and 512V), whole transaction electric voltages and the number of series connections can be adjusted to ensure that they are connected with the inverter, perfect match for PCS (energy storage converter).
III. Large monomer lithium iron phosphate: the cornerstone of safety and longevity in industrial and commercial scenarios
industrial and Commercial energy storage systems are installed in crowded places such as factories and shopping malls. Safety is the uncompromising bottom line.
DGPI-SE-002 adopted large monomer square lithium iron phosphate batteries, this is a firm choice for the safety priority of new energy sources in industrial and commercial scenarios. Thermal stability it is the core advantage-the thermal runaway temperature of lithium iron phosphate is as high as over 500℃, which is stable in abuse scenarios such as acupuncture, extrusion and overcharging. Compared with ternary materials, lithium iron phosphate shows slow heating rather than violent combustion when the heat is out of control, and does not release combustible gas, thus gaining valuable time for personnel evacuation and fire fighting disposal.
large monomer design bring consistency advantages. The number of cell is reduced, the number of serial and parallel connection nodes is reduced, and the cumulative risk of inconsistency between cell is reduced. Aggregate energy new energy performs full inspection and capacity separation for each large monomer cell, and the capacity deviation is controlled within 1% to ensure that the whole package remains balanced after thousands of cycles. Low internal resistance it is another advantage-low internal resistance means less charge and discharge loss and heating. The round-trip efficiency of the system exceeds 95%, and every electric power is efficiently utilized.
Cycle Life excellent as well. The cycle life of lithium iron phosphate batteries can reach more than 6,000 times. In the scenario of industrial and commercial energy storage, the theoretical life is more than 15 years. This means that a set of DGPI-SE-002 energy storage system can save battery replacement during the whole payback period, making the whole life cycle economical.
4. Intelligent BMS: "eHub" of industrial and commercial energy"
DGPI-SE-002 built-in smart lithium battery BMS, is the "eHub" of industrial and commercial energy management ".
Real-time monitoring it covers five core parameters: voltage, current, temperature, SOC and SOH. O & M personnel can view the running status of each battery pack at any time through the local display screen or remote monitoring platform-current power consumption, Today's charge and discharge volume, cumulative cycle times, and estimated remaining life. MultipleWhen concatenated, the BMS automatically aggregates the entire set of data and presents a unified system view.
Six-weight protection build industrial and commercial security defense lines: overcharge protection, overdischarge protection, overcurrent protection, short circuit protection, temperature protection, and active balance. When an battery pack exception occurs, the DMS automatically isolates the instance without affecting the normal operation of other instances, and implements a high-availability architecture of fault isolation and system persistence.
More importantly, BMS supports and industrial and Commercial energy management system (EMS) depth linkage. According to photovoltaic output, load curve, power grid electricity price and demand limit, intelligent optimization of charging and discharging strategy-charging when photovoltaic surplus is available in the daytime, discharging when electricity price is at peak in the evening, cutting the peak when monthly demand approaches the limit, realize the economic optimal scheduling of industrial and commercial electricity consumption.
V. Application scenarios: from "peak-Valley arbitrage" to "multiple values"
the value of DGPI-SE-002 goes far beyond a single energy storage function.
Peak-Valley electricity price arbitrage is a basic scenario. In areas where time-of-use electricity prices are implemented, DGPI-SE-002 charge during the low price period and discharge during the peak price period to earn income from the price difference. Based on the peak-valley price difference of 0.8 yuan/kWh and two cycles per day, the annual income of a 100kWh system can reach 58000 yuan, and the payback period of investment is about 3-5 years.
demand and cost management it is a value-added scenario. The electricity charges of industrial and commercial users include the basic electricity charges charged according to the maximum demand. DGPI-SE-002 discharge during the peak load, reducing the maximum demand and reducing the basic electricity expenditure. For factories and shopping malls with high demand and electricity costs, this income is even beyond the peak arbitrage.
Photovoltaic increase it is a green scene. The power generation period of the roof of the industrial and commercial buildings is closely matched with the load of electricity. In DGPI-SE-002, the electricity is stored at noon, and the lighting and air conditioning are released late, increasing the self-use rate from 30% to more than 80%.
Emergency backup it is a guarantee scenario. When the power network is stopped, DGPI-SE-002 is automatically switched to off-grid mode, providing uninterrupted power supply for critical loads (fire protection, security protection, data center, cold chain) to avoid production loss and data loss.
VI. Adaptation to the wide-temperature zone: all-season Guardian from the southern factory to the Northern Territory
industrial and commercial buildings are distributed from tropical to cold zone, and battery packs need to remain stable in the climate.
DGPI-SE-002 discharge temperature range-20℃ to 60℃, covering the annual climate of China's vast area. Winter northeast factory-20 ℃ cold, BMS pre-heating function to ensure the normal start of the battery; Summer South China shopping mall 40 ℃ heat, temperature protection automatically reduces power, prevent the risk of overheating. Charging temperature range: 0 ℃ to 45 ℃, it is forbidden to charge at low temperature to prevent lithium evolution damage by cell, and it is limited to current at high temperature to protect battery life.
DGPI-SE-002 cabinet energy storage battery, is the modular cornerstone of the "industrial and commercial energy storage solution" of the new energy source. It implements plug-and-play in the form of standard cabinets, covering the whole scene from kWh to MWh with 8 series extensions, protecting safety and longevity with large monomer lithium iron phosphate, and empowering energy management with intelligent BMS, covering the full demand from peak-Valley arbitrage to emergency backup power with multiple values.
