What 珠海东帆科技有限公司 does

DFUN (ZHUHAI) CO., LTD. (珠海东帆科技有限公司), founded in April 2013 and headquartered in Zhuhai, Guangdong, China, is a privately held national high-tech enterprise specializing in Battery Monitoring Systems (BMS) and adjacent power-management hardware and software for mission-critical infrastructure. Its core technology platform continuously monitors voltage, current, internal resistance, temperature, and impedance across heterogeneous battery chemistries — VRLA, Ni-Cd, flooded lead-acid, and lithium — and supports online capacity testing without load interruption, a method that differentiates the company from traditional discharge-based battery testing. The product portfolio spans four production lines: BMS hardware (DFCS4100 and related modules), smart lithium-ion batteries with integrated BMS (including 48V variants), high-accuracy AC/DC smart energy meters, and a cloud-based DFCS4200 Backup Power Management System that enables centralized multi-site battery asset monitoring via SNMP, Modbus, and 4G integrations.

The company sells primarily through direct enterprise field sales augmented by a network of agents in more than 50 countries and 5 domestic Chinese branches, with marketing reinforced by a website localized into 60+ languages and a trade show cadence spanning Data Centre World (Madrid, Paris) and FIEE Brazil. Target verticals are mission-critical infrastructure operators — data centers (Vertiv, Schneider Electric, APC, Delta, Riello UPS, Socomec, True IDC, Nabiax), telecommunications carriers (MTN, NTT, Viettel, Turkcell, Telkom Indonesia, KDDI), power utilities (Tibetan Power Grid), rail and aviation (Prague Metro, Singapore Airport), oil and gas, and energy storage — where unplanned battery failure carries outsized downtime risk. Revenue mechanics are dominated by hardware unit sales, with the company shipping over 1,000,000 BMS units annually and holding 50+ patents in the battery monitoring domain; the cloud platform introduces an emerging recurring software layer on top of the hardware base.

Core offering

DFUN designs, manufactures and sells Battery Monitoring Systems (BMS), smart lithium-ion backup batteries, online battery capacity testers, and AC/DC smart energy meters for mission-critical infrastructure. The company also operates a cloud-based backup power management platform (DFCS4200) that enables centralized multi-site battery asset monitoring across data centers, telecom networks, power utilities, oil & gas, energy storage and rail transportation applications. Over 1,000,000 BMS units are delivered annually to enterprise and government customers worldwide.

Product overview

DFUN (Zhuhai Dongfan Technology) operates three production lines — Battery Monitoring System (BMS) Solution, Energy Meter, and Smart Lithium-ion Battery — delivering an end-to-end portfolio for battery monitoring, testing, and energy management. The BMS serves as the core platform, supporting real-time monitoring of VRLA, Ni-Cd, flooded lead-acid, and lithium batteries across variants tailored for UPS, data center, telecom, power utility, energy storage, oil & gas, and rail/transportation sectors. This core platform integrates with the Smart Battery Capacity Tester for online capacity verification, the Smart Lithium Battery line (including 48V variants) as an intelligent battery with built-in BMS, and the Smart Energy Meter family (AC/DC, multi-channel) for power measurement. A Cloud System platform enables centralized monitoring across distributed sites, while specialized add-on modules such as the UPS Monitoring Controller and DFCS4100/DFCS4200 hardware expand system capabilities.
