System Application
Energy storage improves efficiency by storing surplus energy for later use, reducing waste, cutting costs, and lowering reliance on traditional energy sources.
Designed according to Tier IV data center specifications, it provides real-time backup power and voltage stability through battery storage and fast-switching mechanisms, ensuring critical loads operate normally during power anomalies. The energy storage system stores energy in normal mode and rapidly discharges during power outages, protecting equipment from the impact of power interruptions.
Supports power peak shaving (reducing peak loads) and frequency regulation services (stabilizing grid frequency), lowering electricity costs while enhancing grid stability.
Energy demand fluctuates throughout the day, with peaks during the day and valleys at night. Energy storage technology can store excess energy during low-demand periods to meet high-demand periods, thereby stabilizing energy supply and avoiding energy waste or shortages caused by supply-demand imbalances.
Energy storage enhances grid stability by quickly adjusting to demand fluctuations, ensuring reliable operation and reducing power interruptions.
System Configuration
The system architecture converts electricity generated from solar energy through a Power Conditioning System (PCS), enabling storage in battery modules or direct supply to loads. The Energy Management System (EMS) oversees real-time monitoring, data analysis, and equipment scheduling. Through automated management, it effectively enhances the utilization rate of renewable energy, while reducing energy consumption and mitigating the issue of high power generation costs.

Klacci Low-voltage Parallel
No air conditioning required – natural heat dissipation design saves energy. Ideal for applications with high safety requirements.
Other manufacturers High-voltage Connection
Additional cooling, such as air conditioning or liquid cooling, is needed to ensure system stability.
EMS System Management
This EMS (Energy Management System) is centered around the NextDrive Smart Energy Gateway, which connects all on-site electricity consumption, power generation, and energy storage equipment. Through the NextDrive Cloud platform, data is uploaded to the cloud for centralized management.
The web-based EMS interface allows administrators to monitor and manage energy systems in real time.
Optional Fire Suppression System
This energy storage system combines the electrochemical characteristics of the battery with a self-developed intelligent power controller to effectively solve the voltage matching issue between low-voltage batteries and high-voltage PCS, while simplifying the control system and enhancing safety and performance. Utilizing EDC (Efficient Data Collection and Distributed Control System) technology, combined with thermocouple modules and DIDO control modules, the system can precisely monitor temperature variations within the energy storage cabinet batteries and detect anomalies in real time to ensure safety.
EDC Automatic Fire Extinguishing Function
- The system can be optionally equipped with an automatic fire suppression system. When an abnormal condition is detected, it will automatically activate alarms, cut off power, or release extinguishing agents targeting the thermal runaway cells, extinguishing the fire immediately. This effectively prevents fire escalation and ensures safety.
- This system uses an environmentally friendly, plant-based, non-toxic fire extinguishing agent that can extinguish Class A fires and lithium battery fires. The agent is biodegradable in soil or can be recycled, making it environmentally friendly.
Thermal Runaway Cause Analysis of Competing Systems
The Other Manufacturers’ Systems waterproof design limited the fire suppressant to the outer casing, failing to extinguish burning lithium cells inside. Gas agents cannot put out Class A fires, leading to uncontrolled fire spread.
If lithium batteries fail to detect and control temperature in time, thermal runaway can occur, rapidly generating high temperatures and flammable gases, which may lead to battery module fires or even explosions.
Improper wiring, damaged protective layers, or lack of fire and waterproof planning during installation can lead to short circuits, leakage, and increased fire and equipment damage risks.
The BMS monitors battery voltage, temperature, and status in real time. Failure can cause overcharge and thermal runaway risks.
Relying solely on the BMS for safety protection means that if the BMS fails, the entire system lacks a final line of defense.
