Communication power supply for substations
DFUN DFCT48 Battery Remote Online Capacity Testing System
Suitable for 48V power systems in substations, base stations, and transportation.
Multiple functions include remote capacity testing, energy-saving discharging, intelligent charging, battery monitoring, and battery activation.
Pre-charge function to balance bus voltage differences, preventing high-current charging impacts on batteries.
Electrical isolation between the primary and secondary sides, providing strong anti-interference capabilities and stable operation.
Constant current discharge with boosted voltage, physical circuit isolation, and real load discharge ensures low heat generation and high safety.
Dispersed sites lead to time and operational costs for maintenance.
Lack of effective battery monitoring and alarm functions.
Routine inspections require individual measurements of battery voltage and other information, resulting in a high workload.
Maintenance personnel cannot promptly detect battery failures, posing safety risks.
Manual inspections are time-consuming and labor-intensive, prone to errors, and difficult to record and preserve.
Remote Online Capacity Testing: Enables intelligent digital monitoring of batteries with real-time monitoring and online management. Facilitates remote control of battery charging and discharging, maintenance planning, and automated discharge according to schedule. Maintenance personnel can conduct inspections and manage charging/discharging without being on site, improving efficiency and reducing workload.
Energy Saving and Environmentally Friendly: DC/DC real load discharge with power loss under 5%, reducing carbon emissions. Saves 100 kWh of electricity per site for two capacity tests. According to the International Energy Agency, producing one kWh of electricity releases approximately 0.78 kilograms of CO₂. This translates to an annual reduction of 78 kilograms of CO₂ emissions per site (based on 2V 1000AH batteries).
Intelligent Charging: Enhances safety with three-stage intelligent charging, preventing undercharging and overcharging. Real load discharge ensures safety and energy efficiency. The battery balancing function addresses the phenomenon of voltage differences between the batteries in the battery pack and prolongs the service life of the battery. During charge/discharge cycles, the system maintains battery integration, ensuring uninterrupted power supply even during mains power outages and mitigating discharge risks.
