key benefits

Modular Air-Cooled Power for Scalable Deployment

Maximize every kWh

Scale Power with Growth

Start with 200 kW and expand output to 1200 kW as your site grows

More Energy Delivered

Dynamic power allocation distributes more energy across every outlet

Install up to 24 Outlets

Charge up to 24 vehicles in parallel across your depot site

More Power, Less Space

High power density enables efficient integration and lower operating costs

ENGINEERING EXCELLENCE

Lower Cost per kWh Delivered¹

M-Series power cabinets improve site economics by targeting the lowest cost per kWh over the life of the site

Invest in line with demand

Output is field-upgradable from 200 to 1200 kW across three cabinets, enabling operators to align initial deployment with CAPEX and install more outlets over time. Independent scaling of cabinets and dispensers allows capacity to grow with utilization and fleet electrification – without site redesign or infrastructure replacement.

Superior power delivery

An air‑cooled power cabinet architecture with 50 kW power‑sharing granularity delivers more kWh per site per day with 20% less installed power². Up to 1.2 MW is dynamically shared across as many as 24 outlets, with reduced thermal derating to sustain high performance during periods of peak vehicle demand.

More charging capability
with less space

Delivering the highest power density in its category, M-Series cabinets concentrate megawatt power into a compact footprint of 625 kW/m². The detached dispenser architecture allows operators to install more outlets within site constraints, freeing up parking bays or depot space to increase charging capacity and revenue potential.

¹ The same installed kW delivers more kWh per session, and a smaller installed kW delivers the same kWh per hour. Both outcomes lower the cost per kWh.
² At same high site occupancy (75-100%) and same installed port number (8), at average vehicle kW demand (75-85 kW), our 800 kW system with 50 kW power sharing granularity (M800) delivers the same kWh per day as a market-typical 1000 kW with 62.5 kW power sharing granularity.

The Power Within

Next-generation power modules are developed entirely in-house for improved efficiency and long-term durability.

97 %
Conversion Efficiency

SiC semiconductors deliver up to 97% conversion efficiency and reduce energy costs by 20-40% compared to traditional silicon-based systems.
