Small DC fan for thermal management of lithium batteries and control panel cooling.
Explaining the importance of CAN communication management and thermal measures for lithium batteries. DC fans that can be considered for cooling battery panels and control panels.
The replacement of traditional lead batteries with "lithium-ion batteries" is rapidly advancing as backup power sources for industrial equipment and power sources for AGVs. In particular, smart batteries that support CAN communication can visualize lifespan, remaining capacity, and even "cell temperature" in real-time, significantly contributing to DX maintenance that prevents sudden stops and accidents. The most important factor in maintaining the performance of these lithium batteries and preventing thermal runaway and degradation is "thermal management (heat dissipation and cooling)." If the heat generated during charging and discharging is trapped inside the control panel or battery box, it can lead to reduced lifespan and error stops. Our "small DC fans (AF/BF series)" efficiently exhaust and cool the heat trapped inside battery panels and FA equipment control panels. They can be considered as reliable cooling parts that work in conjunction with a temperature monitoring system via CAN communication to ensure effective heat dissipation during high temperatures.
basic information
■ Key Points of Thermal Management and DX Maintenance for Lithium Batteries - Longevity through Temperature Management: Lithium-ion batteries degrade faster with continuous use in high-temperature environments, making reliable cooling cycles linked to temperature monitoring via CAN communication essential. - Exhaust in Enclosed Spaces: Airflow design that quickly dissipates heat buildup from control panels housing batteries and the enclosed bodies of AGVs is required. ■ Features of Small DC Fans (AF/BF Series) - Wide Range Heat Dissipation (AF Series): High airflow axial fan motors efficiently expel heat from the entire battery panel and control panel to the outside. - Localized Cooling (BF Series): High-pressure DC blower fans deliver pinpoint cooling air to the gaps of heat-generating inverters and battery packs. - Compatibility with DC Drive: Can be directly driven by the DC battery power supply on the equipment side, designed for long life to withstand 24-hour industrial applications.
Price information
We provide overwhelming price competitiveness by leveraging our unique global procurement network (world-standard ODM products) to significantly reduce development and implementation costs. Breaking the common belief that "mass production starts from thousands of units," we offer the same price advantages as mass production even for small-scale production runs of several dozen units, minimizing initial investment and inventory risks for companies.
