■ Three Capabilities to Solve On-Site Challenges 1. Avoiding Communication Errors Due to Severe Outdoor Temperature Changes (From Extreme Heat in Summer to Subzero Temperatures in Winter) SaFT accommodates a wide operating temperature range, including high temperatures from direct sunlight and cold temperatures in winter, achieving stable pulse output at both extremes. This minimizes the risks of "resend costs" and "on-site investigations" associated with data loss. 2. Achieving Maintenance-Free Operation Through "Long Lifespan Characteristics" and Optimizing Total Cost of Ownership (TCO) Thanks to an extremely low self-discharge rate, long-term operation is possible, reducing the frequency of battery replacements. Additionally, by minimizing maintenance after installation and reducing waste batteries, it significantly contributes to environmental burden reduction (SDGs). 3. "High Reliability" Honed in Domestic and International Infrastructure Markets In addition to a wealth of achievements in Europe, a leader in smart meters, there are already proven results in the domestic smart meter market, making it a continued choice in development sites that demand high reliability.

SaFT

[Case Study] Paris Water Authority: Optimization of Smart Meter Operations [Challenges] It was necessary to accurately understand the remaining lifespan of each meter based on the actual usage conditions of the meters installed on-site. Additionally, the traditional uniform replacement cycle could lead to discrepancies with actual usage conditions, resulting in increased costs due to excessive replacements and risks of unexpected failures. [Measures and Results] To continue data acquisition, we analyzed the batteries collected from the field to assess the condition and degradation status of the meters. - Inspection of the battery's appearance and structure (corrosion, leakage, damage, etc.) - Measurement of remaining capacity through SaFT's proprietary analysis - Verification of discharge characteristics and self-discharge - Measurement of internal battery conditions - Analysis of power consumption data based on actual usage environments From these results, we clarified factors affecting lifespan, such as temperature, installation location, and humidity. Based on this, we derived measures to optimize battery lifespan. As a result, it became possible to make planned maintenance and renewal decisions, achieving optimization in the management of meter assets. SaFT not only provides the batteries themselves but also analyzes the factors affecting lifespan and offers recommendations for optimal usage and management methods.
