Industrial and Commercial Energy Storage Solutions
Industrial and commercial energy storage solutions, represented by our integrated outdoor energy storage cabinet product, can achieve various revenue models such as peak-valley arbitrage, dynamic expansion, demand management, demand-side response, and enhancing green energy utilization.
The product primarily targets customers in fields such as industry, 5G base stations, rail transit, new energy charging stations, and zero-carbon parks.
Industrial Parks
Utilizing energy storage technology helps reduce operating costs and enhance the competitiveness of the park.
Energy storage technology can assist zero-carbon parks in better managing their energy usage and distribution, effectively reducing energy costs and thereby further improving the economic competitiveness of the park.
Charging and Battery Swapping Stations
These stations provide charging and fast battery swapping services for electric vehicle batteries.
Using an integrated photovoltaic storage and charging system can effectively reduce the use of municipal electricity, significantly increase the proportion of green electricity, and achieve profitability.
Scenic Spots and Inns
Scenic areas can be equipped with independent energy storage or integrated photovoltaic storage systems to reduce dependence on municipal electricity and ensure stable power supply for the scenic area.
Commercial Buildings
Large shopping malls have distinct electricity usage patterns, and therefore, energy storage can be used for peak shaving and valley filling, demand management to reduce electricity costs. As public spaces, malls often have critical and emergency loads, so energy storage can be installed as a backup power source.
Residential Communities
Community energy storage systems are set up on the distribution network side or the power user side. For residential applications, they are usually deployed in residential communities and installed on street corners or in residential areas.
Typically, charging occurs during low electricity demand periods at night, and discharging is done as needed to improve power quality and supply reliability or to optimize grid load characteristics.
5G Base Stations
Based on typical base station configurations, the power system expansion needs are studied in three scenarios to ensure that 5G base stations have basic energy storage backup functions.
To ensure communication reliability, 5G base stations are usually equipped with high-energy-density, high-cycle-life lithium iron phosphate secondary batteries with good load regulation characteristics.
Application Methods
Peak-Valley Arbitrage
Dynamic Expansion
Industrial and commercial energy storage systems can replace transformer capacity during peak load periods, reducing the overall transformer capacity demand, thus lowering transformer expansion construction costs and subsequent fixed capacity charges or maximum demand charges. In old industrial and commercial scenarios with insufficient power load capacity and additional charging pile construction needs, dynamic expansion can be achieved through energy storage systems without incurring the long lead times and high costs associated with transformer expansion.
Demand Management
In some provinces, large industrial electricity users are charged with a two-part tariff, including electricity price and capacity price. The electricity price is determined by the user’s electricity consumption, while the capacity price is determined by the user’s maximum electricity demand or transformer power capacity.
After installing energy storage equipment, users can reduce their maximum demand and transformer capacity configuration. Energy storage supplements part of the output power, reducing capacity price costs.

BMS Battery Management System
Addresses key issues in lithium battery systems such as safety, availability, usability, and service life.
Ensuring Battery Safety
During battery charge and discharge processes, the terminal voltage and temperature of each battery in the pack, charge and discharge current, and the total voltage of the battery pack are collected in real-time to prevent overcharging or overdischarging.
Estimating Battery State of Charge
Accurately estimates the battery pack’s state of charge (SOC), i.e., the remaining battery capacity, ensuring that the SOC remains within a reasonable range, preventing damage due to overcharging or overdischarging, and reporting the remaining energy of the energy storage battery or its SOC status at any time.

Solution Advantages
This solution, compared to centralized energy storage solutions, offers advantages such as safety, economic benefits, and flexibility.
▷ Safety⸺Modular energy storage products are safer
- Cluster isolation The battery clusters are isolated from each other through PCS, preventing chain reactions within the clusters. Issues like thermal runaway and electrical fires can be effectively contained, enhancing system safety.
- AC-side parallel connection Parallel connection on the AC side to the low-voltage grid avoids direct parallel connection of the battery clusters, controlling the extreme short-circuit current of the battery to below 13KA, ensuring reliable fault disconnection.
- Single-cluster control No circulating currents between clusters, avoiding accelerated aging of battery cells due to circulating currents, greatly improving system reliability.
- Integrated design The battery and PCS are integrated into a single cabinet, significantly reducing DC cables and avoiding the risk of positive-negative short circuits.
▷ Economic⸺Modular energy storage products are managed per cluster
For a 10MWh power station, the energy-saving benefits of modular energy storage are about 10% higher than those of centralized energy storage over 15 years.
▷ Flexibility⸺Starting from 100kW, flexible multi-cabinet parallel connection
- Easy transport and installation Highly integrated pre-installation, light weight and small size of individual cabinets, no need for large cranes, safe and convenient.
- Shorter commissioning time Reduces the amount of on-site commissioning work, resulting in lower overall commissioning costs.
- Efficient maintenance Standardized module design with overall cluster maintenance, making it convenient and flexible.
- Low expansion and power replenishment costs Smaller granularity allows for flexible deployment and smooth expansion.
