Embitel Technologies International presence:

Industrial IoT solution for UPS battery monitoring | Predictive Maintenance

Embitel Technologies International presence:

• Our customer is one of the most respected & renowned suppliers of electric & automation systems for Industrial Plants

• With a strong focus on R&D and quality, over the years our customer has earned the reputation of being a trusted Tier-I supplier of high-quality electric motors and drivers, power electronics equipment, and Uninterrupted Power Supply

• However, during their latest UPS field deployment tests, a critical issue related to timely maintenance was observed.

• The customer had sourced the Valve Regulated Lead Acid (VRLA) batteries from a third-party supplier.

• This meant that, as an industrial automation supplier, our customer could not deliver the advantages of predictive maintenance (no downtime and lower cost of ownership) to its clients.

• Also, due to the absence of an IoT-based predictive monitoring system, any battery failure would have a direct impact on the performance and longevity of the UPS network.

• The customer wanted to minimize this weakness: monitoring the rate of drain of battery charge.

• They approached Embitel for an automated solution that will address the battery health monitoring system

Business Challenge

Embitel Technologies International presence:

Embitel Solution:

• Design and development of an IoT-enabled, industrial grade network of sensors for data collection and monitoring.

• Design and development of a data aggregator and storage system, wherein data can be stored either locally on the device or on an external server.

• Industrial IoT (IIoT) sensors are connected to the local monitoring unit over a wireless LAN connection to minimize the cabling cost. A backup Ethernet connection has also been designed.

• These IoT sensor modules collect the voltage and temperature information from the installed batteries of the UPS.

• The collected data is packaged and forwarded to the local monitoring unit for decision making. To monitor the rate of battery discharge and ensure predictive maintenance, the system has been designed to calculate the string current.

• Thus implementing Ohm’s Law as part of the algorithm, the IIoT monitoring and data analytics system is able to isolate the weakening batteries and notify the local administrator to take appropriate action for predictive maintenance.
