Product Description

Working Principle of Low Voltage Rack-mounted Lithium Battery

1. Core Electrochemical Reaction: Relies on the migration of lithium ions between the positive and negative electrodes to achieve charging and discharging. During charging, lithium ions deintercalate from the positive electrode (e.g., lithium iron phosphate, ternary materials) and intercalate into the negative electrode (typically graphite) through the electrolyte; during discharging, the reverse migration occurs, releasing electrical energy for device use.  
2. Rack-Mounted Structure Adaptation: Battery cells or modules are fixed in a 19-inch rack via standardized brackets. Internal circuits (such as the BMS, Battery Management System) enable series/parallel connections between cells to uniformly output voltage and current, complying with installation specifications for rack-mounted equipment.  
3. Integration of Intelligent Management System: The built-in BMS monitors battery status (voltage, current, temperature, SOC remaining capacity, etc.), prevents risks like overcharging, over-discharging, and short circuits, while optimizing charging/discharging efficiency to extend battery life.  
4.Energy Conversion and Output: Converts the battery's direct current (DC) into stable voltage required by devices (e.g., 12V, 24V, 48V, or 220V) through DC-DC or DC-AC conversion modules, meeting power supply needs in different scenarios.

Our Advantages

1. High Space Utilization: Adopts a 19-inch standard rack design, allowing direct installation in cabinets. It is compatible with servers, switches, and other equipment, saving physical space in machine rooms or energy storage cabins, and is suitable for high-density deployment.  
2. Easy Installation and Maintenance: Modular design supports quick plug-and-play replacement. There's no need for complex wiring, and faulty modules can be replaced individually during later maintenance, reducing downtime and maintenance costs.  
3. Enhanced Safety: The integrated BMS system monitors and warns of abnormal states in real time. Combined with fire-resistant enclosures, overcurrent protection, and other designs, it reduces risks such as thermal runaway and short circuits, making it suitable for sensitive scenarios like machine rooms and data centers.  
4. Long Cycle Life: Uses long-life cells such as lithium iron phosphate, with cycle counts reaching over 2,000 times (some products exceed 5,000 times). The service life is typically 5-10 years, lowering long-term replacement costs.  
5. High Energy Density: Compared to traditional lead-acid batteries, it has higher energy density (usually 100-200Wh/kg), enabling more energy storage in the same volume and improving endurance ability or energy storage capacity.  
6. Environmental Friendliness and Energy Efficiency: Free of heavy metals like lead and cadmium, making recycling and disposal more environmentally friendly. It has high charging/discharging efficiency (usually 85%-95%) with low energy loss, suitable for new energy storage and backup power scenarios.  
7.Flexible Scalability: Supports parallel connection of multiple battery groups to expand capacity or series connection to increase voltage. Configurations can be flexibly adjusted according to load requirements, adapting to scenarios from small backup power supplies to large-scale energy storage systems.

FAQ

FAQ

1. What is the typical service life of rack-mounted lithium batteries, and do they require regular maintenance?
The service life of rack-mounted lithium batteries mainly depends on the cell type and application scenario. Products using lithium iron phosphate cells generally have a cycle life of over 2,000 times, with some high-end models exceeding 5,000 cycles. Under normal usage, their service life is usually 5-10 years. Routine maintenance is straightforward: regularly check battery status (voltage, temperature, SOC, etc.) through the BMS system, and clean the cabinet vents every 1-2 years to prevent dust accumulation from affecting heat dissipation. There is no need for frequent cell or electrolyte replacement, resulting in much lower maintenance costs compared to traditional lead-acid batteries.
2. Can rack-mounted lithium batteries directly replace traditional lead-acid batteries in machine rooms? What should be noted during installation?
Yes, direct replacement is possible, but the following points should be noted:
• Dimensional compatibility: Ensure the height (in U) and depth of the rack-mounted lithium batteries are compatible with the existing lead-acid battery cabinet. Typically, 19-inch standard rack designs can be installed directly.
• Electrical parameter matching: Verify voltage (e.g., 48V), capacity, and maximum charge/discharge current to ensure they match the UPS host or load requirements.
• Safety standards: Disconnect the main power supply during installation, use cables that meet machine room electrical specifications (such as flame-retardant cables), and complete parameter configuration through the BMS system to ensure normal communication with the existing monitoring platform.
3. Can rack-mounted lithium batteries work stably in high or low temperature environments? How to handle extreme temperatures?
Rack-mounted lithium batteries generally have a normal operating temperature range of -20°C to 60°C, but scenario-specific optimizations are required:
• High-temperature environments (e.g., outdoor base stations): Battery packs are equipped with forced air cooling or liquid cooling systems, and the outer casing uses fire-resistant and heat-insulating materials. The BMS automatically adjusts charge/discharge current to prevent thermal runaway.
• Low-temperature environments (e.g., northern machine rooms): Built-in heating modules automatically activate preheating when the temperature drops below 0°C to maintain cell activity. Meanwhile, charging current is limited at low temperatures to prevent lithium dendrite formation, which could affect safety.
• Extreme temperature fluctuation scenarios: It is recommended to use them with machine room air conditioning or temperature-controlled cabinets, maintaining the ambient temperature between 10°C-35°C to maximize battery life.
