Tellus Power Enters Megawatt Race with Nexus Charging System

LAS VEGAS, NV – May 04, 2026 – As the push to electrify commercial transport intensifies, Tellus Power has thrown down the gauntlet with the unveiling of its Nexus Megawatt Charging System (MCS). Announced today at the Advanced Clean Transportation (ACT) Expo, the new system is a high-power, distributed charging platform designed to tackle the immense energy demands of commercial and heavy-duty electric vehicle fleets.

The Nexus MCS, the first product under the company's new Nexus platform, boasts a formidable power output ranging from 600kW to 1.2MW. This positions Tellus Power to directly address one of the most significant hurdles in fleet electrification: the need for rapid charging that minimizes vehicle downtime.

A New Architecture for High-Power Charging

At the core of the Nexus MCS is a distributed architecture built around a centralized power cabinet that feeds multiple, smaller charging dispensers. This design allows fleet operators to manage and distribute high levels of power across several charging points in real time, a critical feature for busy logistics depots where space and time are at a premium.

By centralizing the bulky power conversion electronics, the on-site dispensers can be smaller, quieter, and more flexibly placed. This modular approach is engineered to help operators maximize the number of vehicles that can be charged simultaneously, improving site utilization and overall operational efficiency.

“As electrification scales toward autonomous and commercial light, medium and heavy-duty transport, charging infrastructure needs to deliver more power to more vehicles at the same time,” said Mike Calise, CEO of Tellus Power, in the official announcement. “We believe the Nexus Megawatt Charging System is designed to enable a single high-power DC system to distribute energy to multiple connectors, helping operators maximize site capacity and utilization.”

The system is also designed to support multiple charging standards, a crucial feature in a market with evolving technologies like the emerging MCS standard, CCS, and NACS. This flexibility aims to future-proof infrastructure investments for fleet managers.

Navigating a Competitive High-Power Landscape

Tellus Power is entering a fiercely competitive and rapidly developing market. The race to define the future of heavy-duty charging is on, with established industrial giants already staking their claims. Siemens, for instance, has been promoting its SICHARGE FLEX system, a modular platform offering up to 1.68 MW with dynamic power sharing. Similarly, ABB E-mobility's MCS1200 promises to deliver 1.2 MW of continuous power, aiming to fully charge e-trucks during a driver’s mandatory rest break.

Against these titans, Tellus Power's emphasis on a distributed architecture and system-level power management appears to be its key differentiator. While competitors also offer modularity, the Nexus platform’s focus on synchronous, real-time power allocation across multiple endpoints could provide a tangible advantage in complex, high-throughput depot environments. The challenge for Tellus will be to prove that its system can deliver superior energy efficiency and a lower total cost of ownership compared to the established players.

Solving Fleet Electrification’s Biggest Headaches

The introduction of systems like the Nexus MCS is a direct response to the significant pain points fleet operators face when transitioning to electric. The primary challenge is not always the vehicles themselves, but the immense strain they place on electrical infrastructure. Procuring an electric truck can take weeks, but securing the necessary grid upgrades to power it can take years and incur massive costs.

Unmanaged charging of a large fleet can also lead to crippling demand charges from utilities, which can make up over 80% of a DC fast charging station's operating costs and erode the economic benefits of going electric. The distributed architecture of the Nexus MCS is specifically designed to mitigate these issues. By intelligently managing power flow, the system can perform “peak-shaving,” spreading the electrical load to avoid costly spikes in demand. This dynamic load management ensures that the available grid connection is used to its maximum potential without overloading it, potentially delaying or reducing the need for expensive infrastructure upgrades.

Furthermore, this architecture helps solve the physical constraints of a busy depot. The smaller footprint of the distributed dispensers preserves valuable maneuvering space for trucks and allows for a more scalable and flexible rollout of charging infrastructure as a fleet grows.

Beyond the Charger: A 'Physical AI Economy'

Tellus Power frames the Nexus MCS not merely as a piece of hardware, but as a foundational element of what it calls the “physical AI economy.” This vision extends beyond simply charging vehicles to creating a bi-directional energy ecosystem where fleets can interact intelligently with the grid.

The company’s products aim to unify vehicle charging, battery storage, and vehicle-to-grid (V2G) capabilities. In this model, a fleet of electric trucks becomes a massive, distributed energy resource. Guided by AI algorithms, vehicles could be scheduled to charge during off-peak hours when electricity is cheapest and cleanest. More importantly, during periods of high grid demand, these same vehicles could discharge a small portion of their battery capacity back to the grid, helping to stabilize the electrical system and generating a new revenue stream for the fleet operator.

This V2G capability, powered by intelligent software, transforms a fleet from a massive energy consumer into an active participant in the energy market, enhancing grid resilience and supporting the integration of intermittent renewable energy sources like wind and solar.

A Strategic Launch at ACT Expo

Launching the Nexus MCS at the ACT Expo in Las Vegas is a calculated move. The expo is North America's largest event for clean transportation, and its 2026 edition has a distinct focus on the very technologies Tellus Power is championing: megawatt charging, digital solutions, and the application of AI in logistics. The show floor is buzzing with discussions about closing the gap between vehicle availability and grid readiness, a problem the Nexus platform purports to solve.

The announcement comes amidst a flurry of related activity, with companies like Delta Americas and New Eagle also showcasing their own megawatt-level and smart-charging solutions. This industry-wide momentum underscores the critical need for the powerful, intelligent, and scalable charging infrastructure that Tellus Power and its competitors are racing to provide. The successful electrification of heavy-duty transport hinges on their success, and the Nexus MCS marks a significant new entry in this crucial technological arena.
