Enabling Reliable, Connected EV Charging Infrastructure at Scale
The Challenge
As electric vehicle adoption continues to accelerate worldwide, charging infrastructure providers face growing pressure to deploy networks that are reliable, scalable, and always connected. Some of that pressure comes from governments. For example, chargers funded by the U.S. National Electric Vehicle Infrastructure (NEVI) Formula Program must have an uptime of 97%.
Whether they’re public charging stations or commercial installations for fleets, operators depend on real-time visibility into charger performance, network status, and system health. Reliable connectivity is essential for remote monitoring, diagnostics, billing, software updates, and maintaining the high levels of uptime expected by drivers and charging network operators.
One leading EV charging infrastructure manufacturer faced these challenges while expanding its charging solutions across multiple international markets. The company needed to deliver charging stations capable of operating reliably in diverse deployment environments while supporting the connectivity requirements of modern charging networks.
System reliability is a critical priority and a major challenge. EV charging environments can generate significant electrical noise and often are in locations with weak or no cellular coverage. An example of the latter is U.S. government initiatives to build public EV charging stations on interstates to address the “range anxiety” that is one of the major reasons why drivers hesitate to buy an EV.
“We needed a technology partner that understood the complete charging ecosystem,” explained the customer’s Engineering Director. “Reliable connectivity, dependable system performance, and strong engineering support were all critical to our ability to scale globally.”
Compounding the challenge, the manufacturer was working to aggressive deployment schedules. The company required a partner capable of delivering not only high-quality components, but also the technical expertise, design support, and global supply chain capabilities needed to accelerate development and reduce risk.
The goal was clear: develop a charging platform capable of delivering seamless connectivity, reliable operation, simplified maintenance, and long-term scalability across multiple markets.
The Solution
To help address these requirements, the customer partnered with Taoglas, leveraging its expertise in connected infrastructure, antenna design, and power electronics to support the development of a reliable, scalable connectivity solution for EV charging stations.
The solution features the Taoglas MA8010 Raptor X, a 10-in-1 combination antenna that supports all 3G, 4G, and 5G bands between 600 MHz and 6 GHz. This wideband design maximizes installation flexibility because the antenna can connect to a wide range of operator networks. The MA8010 also supports Wi-Fi® at 2.4 and 5.8 GHz, providing another option for primary or fallback connectivity.
Its dual-band GNSS (L1/L5) delivers high-precision location and timing, which is essential for applications such as time-stamping transactions, managing assets, and helping EV drivers find the nearest charging station. The antenna’s form factor is equally important: a narrow, low-profile housing that strikes the right balance between compact size and strong performance.
The customer also chose the TMYB1-391NL transformer/common mode choke, enabling reliable wireless communications while supporting robust electrical performance throughout the charging system.
Taoglas worked closely with the customer’s engineering team throughout the development process. Technical specialists provided guidance on integration, optimization, testing, and deployment planning, helping accelerate product development and reduce implementation risk.
“Taoglas became an extension of our engineering team,” said the customer’s Product Manager. “Their responsiveness and technical expertise helped us bring our charging platform to market faster while maintaining the performance standards our customers expect.”
The Outcome
By combining advanced wireless connectivity with reliable power electronics components, the customer successfully deployed a scalable EV charging solution capable of supporting multiple applications and deployment environments.
The integration of the MA8010 Raptor X enabled dependable communications across charging networks, providing operators with the connectivity needed to monitor charger status, manage assets remotely, perform diagnostics, and maintain visibility into network performance.
This enhanced connectivity improved operational efficiency by allowing issues to be identified and addressed more quickly, reducing downtime and supporting a more reliable charging experience for end users. For fleet charging deployments, centralized monitoring and management helped streamline operations and improve oversight of charging infrastructure. Public charging networks gained greater operational transparency and improved service reliability.
“Our charging infrastructure is now positioned to support future growth with confidence,” said the customer’s Chief Technology Officer. “The combination of Taoglas technology, engineering support, and global supply capabilities has helped us deliver a more reliable and connected charging experience.”
