In smart power, smart water utilities and Industrial Internet of Things (IIoT) systems, industrial concentrators (data collectors/gateways) act as the communication brain. They collect data from hundreds of terminal nodes and upload it to the cloud.
These devices are usually installed in outdoor meter boxes, utility poles or non-air-conditioned industrial workshops, exposing them to extremely harsh environments. When the main power supply fluctuates or cuts off, the concentrator must rely on backup power to complete final data reporting and alarms.
Among various battery technologies, low-self-discharge nickel-metal hydride (Ni-MH) batteries have become the unsung hero of industrial backup power thanks to their extreme environmental adaptability.
Similar to automotive T-Box, industrial concentrators are often installed in enclosed, poorly ventilated spaces.
High temperature in summer: The internal temperature of outdoor metal cabinets can quickly rise to around 85℃ under intense sunlight. Ordinary lithium batteries are prone to swelling, leakage, and even thermal runaway risks at high temperatures.
Extreme cold in winter: Temperatures in northern regions often drop to -40℃. Many batteries suffer sharp performance degradation at low temperatures, leading to insufficient discharge power and failure of the concentrator to activate the communication module instantly upon power failure.
BPI wide-temperature Ni-MH batteries are specially designed for such extreme environments. Their chemical system maintains stable performance across a wide temperature range, ensuring the concentrator stays online at all times, whether in frozen northern regions or hot southern areas.
Backup batteries for industrial concentrators remain in low-power standby mode for long periods.
Long-term standby: Backup batteries may not be activated for months or even a year, but must deliver energy immediately when the main power is cut off.
Low self-discharge advantage: BPI's low-self-discharge technology ensures the battery retains sufficient power after long-term storage to support positioning and communication tasks, avoiding emergency failure caused by excessive self-discharge.
Once deployed, industrial concentrators typically require a service life of 5–10 years or longer, making frequent battery replacement extremely costly in labor.
Safety redundancy: Ni-MH batteries offer excellent thermal stability and mild failure modes, meeting the high safety redundancy requirements of industrial systems.
IATF 16949 system: BPI applies strict automotive-grade quality management systems to industrial battery production. Full-process traceability from raw material management to finished product inspection ensures consistency and long-term stability of every battery pack.
Concentrators from different manufacturers have varying internal spaces. BPI provides Ni-MH battery packs in multiple specifications, including AAA, AA, SC and more.
Mainstream solutions: Diversified combinations, mainly -cell 3.6V or 4-cell 4.8V configurations.
Personalized matching: Supports customized design based on voltage, capacity and installation space of the concentrator, delivering optimal power support on the premise of safety.
In smart industrial systems, the most critical components are often inconspicuous, yet determine the reliability of the entire factory or power grid. With exceptional stability up to 85℃ and low self-discharge, BPI Ni-MH batteries provide solid and continuous support for your communication systems in unseen places.
