With more than three million electric vehicle (EV) chargers shipped globally and a portfolio that spans energy storage, thermal management, and digitalised power systems, Delta Electronics has positioned itself as a global leader in electrification and sustainable infrastructure.
At the heart of its energy transformation mission is Jim Chen, Vice General Manager of Delta’s Energy System Solutions Business Division, who is helping to drive innovation in megawatt charging, microgrids, and decentralised power architecture.
At e-Mobility Taiwan 2025, Jim Chen delivered a bold vision of an energy ecosystem in transition — highlighting Delta’s drive to address the growing demand for resilient, flexible, and intelligent power supply systems.
“The world’s need for microgrid systems is driven by the massive increase in electricity consumption,” he explained. “In places like the U.S. and Europe, data centre operators are already facing three-year waits to get access to new grid capacity.”
Chen outlined how AI and digital infrastructure are placing enormous strain on traditional grid systems. A single AI search, according to data from Google, consumes nearly 30 times the power of a standard internet query.
“It’s clear that we’re moving from centralised, fossil-based grids to more localised, renewable-enabled systems,” he said.
A Smarter, Greener Grid
Delta’s response is the development of high-capacity microgrids, energy storage systems (ESS), and new-generation DC architectures. These decentralised systems reduce dependency on central grids and integrate local renewable generation with intelligent power distribution and backup.
At the core of these systems are innovations such as Delta’s solid-state transformers (SSTs) and high-efficiency DC-DC converters, which allow rapid response times and bi-directional energy flows.
“We’re seeing data centres evolve into energy trading platforms. They’re not just consuming energy—they’re generating and distributing it,” Chen said.
Delta’s CFE (Carbon-Free Energy) approach goes beyond conventional ESG metrics like RE100.
“RE100 has its limitations — companies may buy green certificates without actually using green power. CFE, however, requires real-time, same-line renewable energy usage, which dramatically changes the design of energy systems,” said Chen.
From Microgrids to Megawatts
Jim Chen’s division is also pioneering megawatt charging infrastructure, a game-changing requirement for long-haul electric trucks.
“Our systems can deliver one to three megawatts of power, essential for charging large vehicles within minutes. We are already deploying these solutions in collaboration with U.S.-based EVgo and other global charging operators,” said Chen.
Delta’s solutions span from modular 50kW chargers for constrained city spaces to 261kWh energy storage cabinets occupying just 1.5 square metres. “Space and speed are key issues in e-mobility, particularly in urban areas. Our compact DC chargers can recharge a Tesla in the time it takes to watch a movie,” added a company representative during the e-Mobility showcase.
Beyond vehicles, Delta’s reach extends into two-wheelers, three-wheelers, and micromobility markets, providing everything from traction motors to swappable batteries and onboard charging systems.
“We’re nurturing an ecosystem of mobility—from scooters in Asia to autonomous vehicles in Silicon Valley,” the company explained, referencing partnerships with Amazon-backed ZOOX and other major players.
“The integration of these elements represents the future of our industry. With microgrids, renewable energy sources can be managed more efficiently, reducing transmission losses and improving reliability,” added Jim Chen. “Our role is to design systems that not only deliver high performance but are also scalable and sustainable. Our megaWatt charging products and energy storage solutions are just the beginning—we envision an interconnected network where every component works seamlessly together for a cleaner, more reliable energy future.”
Delterra: Innovation Rooted in Earth
Chen also introduced Delta’s Delterra brand—its new identity for EV and microgrid solutions. Inspired by the Latin word for Earth, Delterra reflects the company’s mission to create harmony between power and planet.
“Delterra offers scalable energy storage—from 125kW rooftop applications to gigawatt-hour utility-scale projects. Our One Design, 2M Portfolio strategy is designed for modularity and mobility,” Chen said.
This modular thinking extends to Delta’s project delivery. In the Philippines, for example, the company has deployed 16 microgrid islands using containerised ESS units. “By standardising components and integrating control systems, we can cut land use, EPC complexity, and installation time by half,” said Chen.
Global Footprint, Regional Growth
Delta’s footprint spans five continents, with 73 R&D centres and more than 12,000 engineers worldwide. In the Middle East, the company is expanding through its Dubai office and has begun deploying its charging and energy storage solutions across the Gulf region.
“Our strength lies not just in product delivery but in our ability to offer complete solutions—from solar inverters and energy storage to EV infrastructure and grid management,” explained the spokesperson. “We back this up with 24/7 remote monitoring and O&M support to ensure system uptime.”
The Delta Philosophy
Whether enabling zero-emission mobility or future-proofing the digital power grid, Delta’s work is underpinned by a long-term vision and a deep R&D investment strategy. “We invest nearly 8% of our revenues into innovation annually. It’s this commitment that allows us to stay ahead in power conversion, energy management, and automation,” said Jim Chen.
“As we move ahead, the emphasis will increasingly be on creating robust, flexible networks that can withstand disruptions and adapt to rapid changes in energy demand. We are already exploring how digital platforms and automation can optimize our supply chain and operational efficiency,” he added. “The continuous evolution of micro-electronics will play a pivotal role, especially as we incorporate smart grid technologies and predictive maintenance. The future is about integration—merging renewable energy, advanced energy storage, and intelligent power management into a unified system.”
From powering the data centres of tomorrow to charging the fleets of the future, Delta is not just riding the electrification wave — it’s helping shape the current.
“Micro-electronics might sound like a niche segment at first, suggesting something small-scale. However, the micro-electricity networks we develop at Delta are anything but small. They are designed to handle capacities spanning several hundred megawatts. This requires advanced technologies and continuously evolving products — not only to manage power but also to integrate renewable sources, energy storage, and microgrid solutions seamlessly. Essentially, we are building the electrical network of the future, which enables self-sufficient, locally controlled grids that can operate both independently and as part of larger systems.”
