Product Description Working principle of low voltage rack-mounted lithium battery1. Core Electrochemical Reaction MechanismBased on the lithium-ion intercalation/deintercalation principle: During charging, lithium ions deintercalate from the cathode material (e.g., LiFePO4) and migrate through the electrolyte to the anode (typically graphite), where they intercalate. During discharge, lithium ions deintercalate from the anode and return to the cathode, while electrons flow through an external circuit to generate current, enabling electrical energy output.No metallic lithium deposition: In low-voltage systems (usually ≤50V), lithium-ion migration is more stable, avoiding potential metallic lithium plating that may occur under high voltages, thereby enhancing safety.2. Design Logic of Low-Voltage SystemsVoltage matching and safety control: Total voltage is regulated within low ranges (e.g., 12V, 24V, 48V) through series/parallel combinations of individual cells, adapting to low-voltage device requirements (e.g., communication base stations, small-scale energy storage).Reduced circuit complexity: Low-voltage designs eliminate redundant structures like high-voltage insulation and overvoltage protection, simplifying voltage monitoring for the Battery Management System (BMS).3. Integrated Functions of Rack-Mounted StructuresModular energy storage: Multiple cells are integrated into standardized rack structures (e.g., 19-inch racks) to form unified energy storage units, facilitating stacking for capacity expansion and efficient space utilization.Structural support and thermal optimization: Rack enclosures provide mechanical protection while reserving cooling channels. Combined with BMS temperature monitoring, they maintain cells within an optimal operating range (25-40°C).4. Core Role of the Battery Management System (BMS)State monitoring and balancing: Real-time monitoring of cell voltage, current, and temperature. Active/passive balancing technologies equalize cell capacities to prevent overcharging/over-discharging.Safety protection: Triggers overcurrent, short-circuit, and over-temperature protection mechanisms to cut off charge/discharge circuits. Some low-voltage systems integrate low-voltage alarms to prevent device damage from excessive voltage drops.5. Charge-Discharge Energy Conversion ProcessCharging phase: An external low-voltage power source (e.g., charger) supplies direct current. The BMS controls current input, driving lithium ions to migrate from the cathode to the anode for energy storage.Discharging phase: Load demand triggers discharge. Lithium ions return from the anode to the cathode, converting chemical energy into electrical energy, which is supplied to external devices via the rack's output interface.Product ParametersMODELOMS-71Kproduct51.2v 280Ah*5Nominal VoltageDC 51.2vNominal Capacity280Ah *5Dimension moudle483*790*244*5Dimension RACK600*550*912Weight(kg)675KGspecificationsparameterNominal Capacity (KWh)71.68Discharge Cut-off Voltage (V)40Charge Cut-off Voltage (V)56.8Recommend Charge/Discharge Current (A)450Max Charge/Discharge Current(A)500Parallel FunctionSupport 10 units in ParallelOur Advantages1. Enhanced SafetyThe low-voltage system (≤50V) significantly reduces electric shock risks and minimizes hazards like high-voltage arcing and insulation failure.Combined with precise BMS protection, it effectively prevents overcharging, over-discharging, and short circuits, lowering the probability of thermal runaway.2. Excellent Energy Efficiency and AdaptabilityDirectly compatible with low-voltage DC loads (e.g., communication equipment, small-scale energy storage), eliminating DC-AC conversion steps and reducing energy loss (conversion efficiency improved by 5%-10%).Stable voltage output reduces impact on sensitive devices, extending the service life of connected loads.3.

Enterprise Exhibition Purchase NoticeFAQ1. What is the optimal operating temperature range for rack-mounted low-voltage lithium batteries? What happens if they are used in extreme temperatures long-term? The ideal operating temperature for rack-mounted low-voltage lithium batteries is 25-40°C. Long-term use in environments below 0°C can reduce charge-discharge efficiency and accelerate capacity degradation. In temperatures above 50°C, the BMS may trigger overheating protection, causing frequent power interruptions, while also accelerating cell aging and shortening battery lifespan. It is recommended to maintain a suitable temperature through rack cooling designs or environmental temperature control equipment. 2. What compatibility issues should be noted when paralleling multiple rack-mounted low-voltage lithium battery modules for capacity expansion? For parallel expansion, ensure all modules have consistent voltage specifications (e.g., 48V) and matched cell types and capacity parameters (avoid mixing new and old batteries). Additionally, confirm that the BMS supports parallel communication protocols to ensure balanced current distribution among modules and prevent overload of individual units. It is advisable to use products from the same brand and batch, and follow the manufacturer's expansion guidelines to avoid system failures due to compatibility issues. 3. How should rack-mounted low-voltage lithium batteries be maintained during long-term storage to prevent capacity loss? Before long-term storage, charge the battery to 50-70% (avoid full charge or deep discharge) and disconnect external loads. Store the battery in a dry, well-ventilated area with temperatures controlled between 10-30°C, away from fire sources and corrosive substances. It is recommended to recharge the battery every 3 months to maintain a 40-60% charge level, while using the BMS to check cell status and ensure no abnormal individual cell voltages. For storage periods exceeding 1 year, perform a full charge-discharge cycle to reactivate cell performance.
