Key Takeaways (TL;DR)
Exicom has commenced manufacturing liquid-cooled power modules for EV chargers at its Hyderabad Smart Manufacturing Facility, marking India’s debut in producing this advanced class of power electronics for international markets. These modules are specifically designed to significantly enhance the reliability and longevity of EV charging infrastructure by mitigating thermal stress, a leading cause of component failure. Initially destined for Tritium’s DC charger portfolio in North America and Europe, the technology will subsequently be integrated into Exicom’s own Harmony DC chargers and deployed for charge point operators, fleets, and OEMs in India, leveraging the strategic acquisition of Tritium in 2024. This initiative underscores Exicom’s commitment to localized, cutting-edge manufacturing, aiming to drive technological autonomy and faster adaptation for global and domestic EV charging solutions.
India Forges Ahead in EV Charging Innovation with Exicom’s Pioneering Manufacturing
Exicom, a prominent player in the electric vehicle (EV) charging sector, has commenced the production of liquid-cooled AC and DC power modules at its state-of-the-art Hyderabad Smart Manufacturing Facility. This significant development positions Exicom as the first company in India to produce this advanced class of power electronics, specifically designed for global markets.
This strategic manufacturing move represents a substantial leap forward in the capabilities of India’s EV ecosystem, addressing critical challenges related to charger reliability and performance, particularly in high-power applications. The introduction of these liquid-cooled power modules for EV chargers is set to bolster the global supply chain for EV charging infrastructure while enhancing the resilience of fast chargers.
Addressing Thermal Challenges in EV Charging
The operational environment of EV chargers, especially fast chargers, often subjects power electronics to extreme thermal stress. This stress is a major contributor to component degradation and premature failures, impacting the overall reliability and operational lifespan of charging stations.
Reliability studies cited by Exicom indicate that approximately 60% of power electronics failures are attributable to thermal stress. Furthermore, a temperature increase of just 10°C to 15°C can effectively double a component’s failure rate, highlighting the critical need for superior thermal management solutions in modern EV charging systems.
Traditional air-cooled systems often struggle to maintain optimal internal temperatures, especially in demanding climates or during continuous high-power operation. This vulnerability leads to increased maintenance costs, reduced uptime, and a less dependable charging experience for EV users.
The Liquid Cooling Advantage: Enhanced Reliability and Longevity
Liquid cooling technology offers a compelling solution to these challenges. By circulating a specialized coolant directly through the power modules, internal temperatures can be maintained significantly lower—approximately 10°C cooler than what is typically achieved with air-cooled systems.
This consistent thermal management directly translates to enhanced reliability and extended operational longevity for EV chargers. Components operating at lower, more stable temperatures experience less stress, reducing the likelihood of premature failure and ensuring consistent performance even under heavy loads.
Anant Nahata, Exicom’s CEO and Managing Director, underscored the practical impact of this innovation. “Anyone who has stood next to a fast charger on a 45-degree afternoon knows what heat does to electronics. EV Charging is getting faster with chargers running more hours a day, and customers expect them to work every season and at every site,” Nahata stated, emphasizing the real-world benefits of robust thermal management.
Robust Design for Harsh Environments
Beyond superior cooling, the liquid-cooled power modules for EV chargers boast a fully sealed construction. This design is engineered to protect critical internal components from common environmental aggressors such as dust, moisture, and salt air, which are notorious for shortening charger life in field deployments.
The sealed architecture, combined with effective cooling, ensures continuous operation under load, maximizes power delivery within a compact footprint, and contributes to lower operating costs over the module’s lifetime. This makes the technology particularly suitable for deployment in diverse and often challenging global environments.
Global Reach and Strategic Integrations
The initial production batches of these advanced liquid-cooled power modules for EV chargers are primarily earmarked for international markets, specifically North America and Europe. They will be integrated into Tritium’s comprehensive DC charger portfolio, including the TRI-FLEX and DC-FLEX models, enhancing their performance and reliability in these key regions.
This strategic allocation is a direct result of Exicom’s acquisition of the DC fast charging company Tritium in 2024. The acquisition allowed Exicom to inherit and build upon Tritium’s established in-house liquid-cooled capabilities, refining this class of module across some of the most demanding charging environments globally.
In subsequent phases, this cutting-edge technology will be made available closer to Exicom’s own customer base in India. This includes charge point operators, large fleet owners, and original equipment manufacturers (OEMs) through Tritium’s range of DC fast chargers, which are already being deployed across the nation.
Furthermore, Exicom plans to integrate this innovative liquid-cooled architecture into its proprietary Harmony DC chargers, ensuring that its domestic product line benefits from the same advanced thermal management and reliability enhancements that are being supplied to international markets.
The Hyderabad Smart Manufacturing Facility: A Hub of Innovation
The Hyderabad plant is central to Exicom’s manufacturing strategy, representing a significant investment in advanced production capabilities. The facility is equipped with a high degree of automation, ensuring precision and efficiency in the manufacturing process.
Key features of the plant include digital traceability, which allows for meticulous tracking of each component and module throughout its lifecycle, and specialized testing protocols designed to ensure the highest standards of quality and performance for the liquid-cooled power modules for EV chargers. This facility is poised to serve both domestic and international market demands, solidifying India’s position in advanced power electronics manufacturing.
Nahata emphasized the strategic importance of localized production. “Globally, liquid cooling has become the architecture of choice for high-power charging. We are bringing this technology to India. Local manufacturing matters because we now own more of that technology ourselves. We can engineer it, improve it and adapt it faster, for our customers here and across the world,” he articulated, highlighting the benefits of greater technological autonomy and agility.
Driving the Future of EV Infrastructure
Exicom’s foray into manufacturing liquid-cooled power modules for EV chargers marks a pivotal moment for India’s role in the global EV supply chain. By introducing a technology that significantly improves the reliability and efficiency of charging infrastructure, Exicom is not only addressing current industry pain points but also future-proofing EV charging networks against the demands of faster charging and increased utilization.
This initiative aligns with the growing imperative for robust and dependable EV charging solutions worldwide. As electric vehicle adoption accelerates, the underlying infrastructure must evolve to meet the challenges of continuous high-power delivery in diverse climates and operating conditions. Exicom’s commitment to localized, advanced manufacturing underscores a broader trend towards self-reliance and technological leadership in critical sectors.
The company’s strategic integration of Tritium’s proven liquid-cooled technology, combined with its own manufacturing prowess in Hyderabad, positions Exicom as a crucial enabler for the ongoing expansion and enhancement of the global electric vehicle charging ecosystem.
