Industry News

Driven by the dual-carbon strategy and the development of new power systems, industrial and commercial energy storage, grid-side energy storage, and solar-storage integrated projects have been deployed on a large scale. Ensuring the safe and stable operation of energy storage equipment, extending battery life, and guaranteeing project returns have become core pain points of the industry. Traditional manual inspection is characterized by lagging response, passive fault repair and unforeseen hidden dangers, which easily lead to safety risks and asset loss.

Drawing on years of accumulated experience in the R&D, production and manufacturing of energy storage products, Xinrui Energy has built an integrated energy storage operation and maintenance service system featuring intelligent technology and standardized management. Supported by self-developed intelligent monitoring platforms, high-precision professional testing equipment, certified senior operation and maintenance teams, and a standardized closed-loop service process, we realize the transformation from passive fault handling to active predictive maintenance, providing full-life-cycle entrusted operation and maintenance solutions for various energy storage projects.

I. Solid Professional Strength to Consolidate Technical Foundation

1. Professional Operation & Maintenance Team with Manufacturing Background

Xinrui Energy has in-depth experience in the energy storage equipment manufacturing industry. Our core operation and maintenance engineers have participated in the whole process of R&D and production of battery PACK, PCS, liquid-cooled energy storage cabins, BMS/EMS systems. They are proficient in the full-set equipment principles including battery electrochemical characteristics, electrical control logic, thermal management and fire linkage systems. Different from general third-party operation and maintenance teams, we have an in-depth understanding of the underlying design of energy storage equipment, which enables us to accurately locate in-depth problems such as battery attenuation, line loss and thermal management failure. We eliminate hidden dangers of equipment abnormal operation from the source and maximize the safety control and system performance of energy storage systems.

2. Complete Professional Testing Equipment for All-round Accurate Inspection

Equipped with a full range of high-precision industrial testing tools, we realize three-dimensional and dead-angle-free accurate detection of station equipment, outdoor cabin bodies and battery packs:

- Infrared Thermal Imager: Captures thermal abnormalities of battery cells, wiring terminals and distribution cabinets in real time, and early warns of thermal runaway risks such as temperature rise and short circuit;

- High-precision Internal Resistance Tester: Detects battery internal resistance pack by pack, accurately identifies battery attenuation and consistency differences, and provides data support for balanced maintenance;

- Intelligent Inspection UAV: Completes high-altitude and long-distance rapid inspection for large-scale energy storage power stations and outdoor distributed energy storage cabins, reduces safety risks of manual high-altitude operation, and fully covers the appearance, heat dissipation and safety facilities of cabin bodies.

Supported by complete auxiliary tools such as high-voltage multimeters and insulation detectors, we realize all-round non-destructive detection of hardware, electrical systems, fire protection systems and operating environments.

3. 7×24h Intelligent Cloud Platform for Uninterrupted Online Monitoring

As the "digital brain" of energy storage power stations, our self-developed intelligent operation and maintenance platform opens up the data links of BMS, PCS, temperature control, fire protection and power distribution systems, realizing millisecond-level real-time data collection and centralized visual monitoring of the whole station. It continuously monitors hundreds of core operating parameters including voltage, current, SOC, temperature, pressure difference, charge-discharge power and cabin temperature & humidity, with data reports and historical curves available on both PC and mobile terminals.

The AI intelligent early warning mechanism analyzes equipment operation trends through big data algorithms, actively identifies potential hidden dangers such as deteriorating battery consistency, temperature control faults, insufficient fire pressure and line aging, and pushes multi-level alarms at the early stage of faults. It eliminates risks in the bud, greatly reduces the probability of sudden shutdowns and safety accidents, and truly realizes prevention before failure.

II. Full-process Standardized Service System for Closed-loop Management

Xinrui Energy has established unified, implementable and traceable standard operation specifications for energy storage operation and maintenance, covering full scenarios of daily inspection, periodic professional maintenance and fault emergency response, forming a complete service closed loop of "online monitoring - regular maintenance - hierarchical rush repair".

1. Routine Daily Inspection to Secure Basic Operation

We conduct item-by-item verification in accordance with standardized inspection lists to avoid missing detection:

- Hardware Status: Inspect the appearance, connection tightness and insulation performance of battery modules, converters, distribution cabinets, cables and circuit breakers;

- Environmental Control: Check the operating conditions of energy storage cabin air conditioners, liquid cooling heat dissipation systems and ventilation equipment, as well as the temperature, humidity, dust and waterproof tightness inside the cabin;

- Fire Protection System: Verify the functions of gas fire extinguishing devices, smoke & temperature sensors, fire pipelines, pressure relief devices and emergency power supplies to ensure the safety system is always ready for use.

2. In-depth Periodic Professional Maintenance to Extend Asset Life

Based on battery cycle characteristics and equipment loss rules, we carry out regular professional maintenance to alleviate battery attenuation and improve the available capacity of the system:

- Quarterly Balanced Maintenance: Correct battery pack voltage difference and SOC deviation, optimize battery consistency and reduce capacity loss;

- Annual Capacity Calibration: Complete full charge-discharge cycle tests, accurately calibrate the actual available capacity of batteries, issue battery health assessment reports, and optimize charge-discharge operation strategies.

We also conduct in-depth maintenance including equipment dust removal, fastening, software upgrade and grounding resistance re-testing to delay equipment aging.

3. Hierarchical Response Mechanism for Efficient Fault Disposal

We establish a three-tier hierarchical emergency response process to balance operation efficiency and fault solving speed:

- Primary Response (Remote Diagnosis): Once an alarm is triggered, the operation and maintenance monitoring center remotely retrieves data, analyzes fault types and abnormal points online, and completes parameter debugging and strategy revision to solve most minor faults remotely and efficiently;

- Secondary Response (On-site Service): For faults that cannot be eliminated remotely, we dispatch regional operation and maintenance engineers to conduct on-site detection and parts replacement;

- Tertiary Response (Expert Rush Repair): For major and complex faults such as battery failure, PCS damage and thermal management system breakdown, the headquarters R&D and expert team will provide special on-site rush repair services to minimize shutdown time and stabilize project power generation and peak-valley arbitrage benefits.

III. Core Values of Xinrui Intelligent Operation & Maintenance
