Project Background: Green Transformation Needs of Traditional Industries
As policies tighten requirements on carbon emissions in the industrial sector, enterprises urgently need to optimize their energy structures to achieve sustainable transitions. Leveraging its technical expertise in the new energy field, Imax Power proposes a “photovoltaic-storage-charging integrated solution” tailored to the power consumption characteristics of industrial parks (e.g., daytime production peaks overlapping with PV generation periods, nighttime grid dependence). The solution aims to enhance clean energy utilization and reduce corporate electricity costs through synergistic coordination of photovoltaic power generation, energy storage peak shaving, and intelligent charging.
Technical Solution: Three Core Systems Forming a Smart Energy Closed Loop
The project adopts a deeply integrated model of “photovoltaic power generation + energy storage peak shaving + intelligent charging” with a total capacity of 5MWh. Imax Power provides end-to-end services from design and deployment to operation and maintenance. The core systems include:
1. High-Efficiency Photovoltaic Power Generation System
The project utilizes idle rooftops and parking lot canopies within the park to install high-efficiency monocrystalline PV modules, with a total installed capacity of approximately 3MWp (calculated based on matching the 5MWh storage capacity and charge-discharge strategies). The annual power generation reaches approximately 4 million kWh, meeting about 30% of the park’s daytime production electricity demand. The PV system employs Imax Power’s self-developed MPPT (Maximum Power Point Tracking) technology, achieving a conversion efficiency of over 98%. Stable power generation is ensured even in rainy weather, maximizing solar resource utilization.
2. Intelligent Energy Storage Peak Shaving System
The energy storage system serves as the project’s “energy hub,” utilizing 20 sets of Imax Power’s Imax125-261L integrated energy storage cabinets (125kW/261kWh each) for a total capacity of 5MWh. The product features:
- Liquid-cooled temperature control technology, maintaining cell temperature differences ≤3°C across the cabinet, with a cycle life exceeding 8,000 cycles.
- 314Ah large-capacity cells, enhancing energy density by 15% and system efficiency by over 90%.
- Active fire protection, explosion venting devices, and AC/DC triple-level protection to ensure operational safety.
The energy storage system achieves intelligent dispatch via an EMS (Energy Management System): charging during daytime PV surplus and discharging during nighttime peak demand to stabilize grid fluctuations. It also participates in peak-valley electricity price arbitrage to further reduce costs.
3. Photovoltaic-Storage-Charging Intelligent Charging Network
The project includes 10 DC fast chargers (60kW) and 20 AC slow chargers to meet the charging needs of employee vehicles and logistics fleets within the park. Charging piles are linked with the energy storage system, prioritizing the use of PV and stored energy, with residual demand connected to the grid. Support for V2G (Vehicle-to-Grid) functionality allows electric vehicles to act as “mobile energy storage units,” feeding power back to the grid during peak demand and participating in grid peak shaving.
Economic Benefits: Cost Reduction, Efficiency Enhancement, and Diversified Returns
Post-operation, the project delivers multiple economic benefits:
- Reduced Electricity Costs: Through “self-generated power usage + peak-valley arbitrage,” enterprise electricity costs are lowered by 15–20%, saving over RMB 800,000 annually (based on Hebei’s industrial peak-valley electricity price difference of RMB 0.7/kWh).
- Enhanced Green Power Utilization: Synergy between PV and energy storage increases the park’s clean energy share to 40%, reducing purchased electricity by approximately 4 million kWh/year.
- Ancillary Service Revenue: The energy storage system participates in grid peak shaving and demand response market transactions, generating over RMB 300,000 in annual revenue.
Social Benefits: Green Transition and Industrial Demonstration
The project reduces annual CO₂ emissions by approximately 3,200 tons (equivalent to substituting 1,200 tons of standard coal), comparable to planting 180,000 trees, significantly lowering the park’s carbon footprint. As a demonstration project for integrated photovoltaic-storage-charging solutions in Hebei, it provides a replicable low-carbon transition pathway for high-energy-consuming industries like textiles and logistics, advancing regional green energy restructuring.
Imax Power: Full-Lifecycle Services Ensuring Project Success
As a national high-tech enterprise, Imax Power leverages 16 years of expertise in lithium batteries and power energy technology to deliver “design-deployment-operation” integrated services:
- Customized Design: Optimizes PV capacity and energy storage allocation based on park load profiles and solar resources.
- Rapid Deployment: Prefabricated energy storage cabinets enable on-site installation in just 2 weeks, significantly shortening project timelines.
- Smart O&M: The EMS enables full-lifecycle monitoring, remote OTA upgrades, and fault预警（应为pre-warnings, 建议改为 pre-warnings or early warnings） to ensure system stability.
The Hebei 5MWh integrated photovoltaic-storage-charging project exemplifies Imax Power’s commitment to driving green transitions in traditional industries through technological innovation. As this model scales across industrial parks, it will inject strong momentum into achieving “dual carbon” goals and pioneer a new era of smart energy.
