High-Performance LTE Modules Enable Real-Time Urban Battery Swapping Ecosystem

As a global leader in smart energy exchange platforms for electric scooters, our client's business model relies on a dense network of "Battery Swapping Stations" deployed throughout urban streets. To provide users with a seamless "swap-and-go" experience, these stations must operate 24/7, transmitting battery exchange logs, user payment details, and Battery Management System (BMS) health data to the cloud control center in real-time.

Since most stations are located outdoors—on sidewalks, under overhangs, or at gas stations—they face two primary challenges: First, Environmental Variables: The equipment must withstand long-term exposure to high summer temperatures, humidity, and urban dust. Standard commercial communication devices often fail under such conditions. Second, Zero-Error Data Transmission: Swapping stations involve financial transactions and energy safety. Network downtime or packet loss can lead to payment failures, causing customer complaints, or prevent the monitoring of critical anomalies like battery overheating. Consequently, Client A required a communication module with high maturity, extensive coverage, and easy integration to serve as the neural hub of their energy network.

The EXM-G1A Communication Module, powered by the market-proven Qualcomm Snapdragon X12 LTE Modem, is engineered for IoT applications demanding high reliability and wide-area coverage.

• Robust LTE Cat 12 Connectivity: Supports Carrier Aggregation (CA), maintaining excellent throughput even in dense urban areas, ensuring data uploads remain uncongested during peak usage hours.

• Standard M.2 Interface: Utilizes the industry-standard M.2 form factor, offering high compatibility and ease of replacement. This significantly lowers the barrier for hardware integration and simplifies future maintenance.

• Superior Environmental Tolerance: Optimized for heat dissipation and interference resistance in outdoor settings, ensuring stable connectivity performance even within cabinets exposed to direct summer heat.

Benefits Achieved by the Client

1. Guaranteed Accuracy of Transaction and Operational Data: Leveraging the stable connectivity of the SDX-12, Client A achieved a data transmission success rate of over 99.9%. This ensures every swapping fee is calculated precisely, enhancing user trust.

2. Real-Time Remote Monitoring and FOTA: The high-speed LTE network allows the client to monitor battery inventory across thousands of stations instantly. It also enables Firmware Over-The-Air (FOTA) updates to fix software issues remotely, drastically reducing the operational costs associated with on-site engineering visits.

3. Accelerated Deployment Efficiency: The plug-and-play nature of the M.2 interface, combined with broad frequency band support, allows Client A to expand into new cities or deploy new stations without redesigning their hardware architecture, significantly shortening Time-to-Market.
