Huizhou Energy Storage Container House

The following are the relevant enterprises and product characteristics of energy storage container houses in Huizhou:

I. Main Production Enterprises

1. Huizhou Hesheng Container Manufacturing Co., Ltd.
   Located in Renshan Town, Huidong County, it designs and manufactures standard containers, special containers, and energy storage containers. The products are welded with high-strength weathering steel CORTEN A, suitable for both sea and inland transportation. The container types cover international standards such as 20GP/20HC, 40GP/40HC, and 45HC. The energy storage containers enhance corrosion resistance through a three-layer coating process of anti-rust zinc-rich primer, intermediate paint, and topcoat.

2. Huizhou Huiji Special Equipment Manufacturing Co., Ltd.
   Specializing in prefabricated modular special containers, it provides structural development, system integration, and engineering services for products such as data centers, energy storage equipment, and power modules. Its energy storage containers have integrated capabilities for temperature control, fire protection, and monitoring, suitable for industries such as information new energy, modular buildings, and e-commerce logistics.

3. Guangdong Yunzhi Technology Development Co., Ltd.
   With high safety and long lifespan as its core advantages, its energy storage containers use patented thermal insulation materials (thermal conductivity coefficient ≤ 0.03W/m·K), equipped with a self-developed BMS system for abnormal alarms within 3 seconds, and integrate aerosol and pipe network water spray fire protection systems, with thermal diffusion suppression taking only 8 seconds. The battery cells come with an 8-year or 6000-cycle warranty, and the system as a whole has a 5-year warranty, supporting remote operation and maintenance via the Yunzhi APP.

II. Product Technical Characteristics

1. Safety Protection System

   • Physical isolation: Low thermal conductivity materials are used between battery cells, ensuring that the temperature rise of adjacent cells is ≤ 5℃ when a single cell experiences thermal runaway.
   • Active early warning: The BMS system continuously monitors voltage, temperature, and internal resistance, triggering audible and visual alarms for abnormal data.
   • Passive fire suppression: The dual system of aerosol and water spray works in tandem, with a response speed higher than the industry average.

2. Environmental Adaptability Optimization

   • Temperature control: The inner and outer layers of the container are sprayed with graphene anti-corrosion coatings, combined with a variable-frequency air conditioning system to maintain the battery cell operating temperature between 22-25℃.
   • Humidity management: Optimized sealing design is implemented to prevent short circuits caused by condensation, considering Huizhou's average annual humidity of 78%.

3. Cycle Life Guarantee

   • Charge-discharge management: The SOC usage range is locked between 20%-90% to avoid damage to the lattice structure from deep charging and discharging.
   • Thermal management system: The temperature difference between battery cells is controlled within ±1.5℃ to slow down the rate of capacity degradation.

III. Application Scenarios and Supporting Services

Energy storage containers are widely used in industrial and commercial energy storage projects, data center backup power supplies, and grid peak shaving scenarios. Local enterprises in Huizhou provide after-sales guarantees such as 4-hour on-site response and a 95% core spare parts inventory reserve rate. Some manufacturers support customized designs, such as integrating photovoltaic power generation modules or emergency power interfaces.
