Case Study
-
In mission-critical facilities such as airports, data centers, and large campuses, backup power reliability is essential. Managing thousands of batteries in UPS systems has become increasingly complex, and traditional maintenance methods are no longer sufficient. -
How remote battery capacity testing and an advanced battery monitoring system (BMS) help substations operate safely in extreme high-altitude environments. Through a real-world project in Tibet, DFUN demonstrates how online battery capacity testing for lead-acid battery banks improves reliability, reduces maintenance costs, and ensures uninterrupted backup power for critical grid operations. -
As urban transportation systems continue to modernize, ensuring the reliability of emergency power supply has become a critical safety requirement. In a recent deployment, DFUN proudly delivered a comprehensive Battery Monitoring System (BMS) solution to the Prague Metro system in the Czech Republic
