In modern critical infrastructure, DC power supply system plays a vital role in providing stable and reliable power for substations, data centers, rail transit systems, and other key applications.
However, the operational challenges of traditional series DC power systems are increasingly becoming a bottleneck that limits the safe and stable operation of power systems.
With years of power system development and on-site service experience, Tieon Energy has introduced a parallel DC power supply system that fundamentally addresses these issues, ushering in a new era in DC power system maintenance and operations.

Operational Challenges of Traditional Series DC Power Supply Systems
1. System Reliability Concerns
Traditional series DC power supply system faces significant “weakest link” dilemmas — a failure in any single battery cell can lead to the failure of the entire battery bank, severely impacting system reliability. According to incomplete statistics, up to 83% of DC power system failures are due to battery issues, highlighting the inherent design flaws of traditional systems.
2. Complexity and Cost Pressure in Maintenance
2.1 Cannot Perform Online Maintenance:
Traditional systems do not support online battery replacement, requiring offline operations for each maintenance task.
2.2 Heavy Capacity Verification Workload:
Verifying the capacity of a battery bank requires at least two people working for 2 to 3 days, resulting in high labor costs.
2.3 Difficult Spare Management:
To address potential failures, a large number of spare batteries of the same model must be kept in stock, increasing management complexity.
2.4 High Replacement Costs:
When part of the battery pack fails, the entire group often needs to be replaced, even though most cells may still be functional.
2.5 Significant Power Outage Risks:
Each offline battery maintenance operation poses a risk to the continuous power supply of the DC system.
These issues not only increase the workload of maintenance personnel but also significantly reduce system reliability and economic efficiency, posing potential threats to the safe and stable operation of critical infrastructure.

The parallel DC power supply system enables online battery replacement and maintenance, bringing revolutionary changes to maintenance work:
1.1 Battery Online Replacement:
A single faulty battery does not affect the entire system’s normal operation, allowing for direct online replacement without power outages.
1.2 Mixed Use of New and Old Batteries:
The system supports the mixed use of batteries from different times, brands, and types, significantly improving battery resource utilization efficiency.
1.3 Enhanced Maintenance Safety:
Avoids the risks associated with power outage operations, enhancing maintenance safety and efficiency.
2. Automatic Capacity Verification: A Leap in Maintenance Efficiency
Traditional series DC power systems have cumbersome and time-consuming capacity verification processes, while parallel systems achieve fully automated capacity verification through intelligent design:
2.1 Automatic Online Capacity Verification:
The system can automatically execute full-capacity verification of batteries without requiring manual on-site operations.
2.2 Smart Report Generation:
After capacity verification, standardized reports are automatically generated, reducing the workload of maintenance personnel.
2.3 Convenient Data Export:
Capacity verification data can be exported via USB interface for easy management and in-depth analysis.
2.4 Significant Cost Savings:
Compared to traditional series systems, it saves labor costs, electricity costs, and time costs.
This function not only significantly reduces labor costs but also improves the accuracy and objectivity of capacity verification through standardized procedures, providing a scientific basis for battery management and making maintenance decisions more precise and efficient.
3. Modular Design: The Smart Choice for Flexible Expansion
The modular design of the parallel DC power supply system brings unprecedented convenience to maintenance work:
3.1 Modular Plug-and-Play Maintenance:
Parallel modules use hot-swappable structures for quick and easy installation and replacement.
3.2 Flexible Capacity Expansion:
The modular parallel power supply design allows system capacity to be increased or decreased, supporting “plug-and-play” expansion to meet varying load demands.
3.3 Standardized Design:
The system can adopt unified standard designs to simplify installation processes, lower technical barriers, and improve maintenance efficiency.
3.4 Flexible Power Supply Arrangement:
Supports both distributed and centralized DC power supply arrangements, allowing selection based on demand.
Modular design not only simplifies daily maintenance but also provides significant convenience for system upgrades and capacity expansion, enabling power systems to flexibly respond to changing power needs.
4. Intelligent Management System: A New Digital Maintenance Experience
The parallel DC power supply system is equipped with advanced intelligent management systems, providing comprehensive support for maintenance work:
