Revolutionizing HPC with Next-Gen Power Cube

EXP600K3

As electric vehicles (EVs) continue to evolve in scale, range, and application—from passenger cars to commercial buses and heavy-duty electric trucks—the demand for ultra-fast, high-power charging (HPC) infrastructure is accelerating. Charge point operators (CPOs) and system integrators increasingly seek for power conversion solutions that combine scalability, modularity, and operational efficiency to meet dynamic site demands. To address these needs, Infypower High Power Cube provides a highly configurable, scalable, future-proof power conversion platform dedicated for diverse HPC and megawatt-scale charging installations.

This Power Cube is an air-cooled, rack-style power conversion cabinet engineered for both indoor and outdoor installations. It’s equipped with 20 standardized power module slots, delivering up to 600kW/800kW of total charging power depending on module configuration.

The Power Cube features 2 AC input channels, and 1 to 12 DC output channels, connecting up to 12 charging plugs and allowing simultaneous charging of up to 12 EVs. For megawatt scalability, two cabinets can be paralleled with a total of 1.2MW/1.6MW power converged onto a single bus, achieving MCS for heavy-duty charging applications.

Designed for durability, the Power Cube is built with full safety protections, including input contactor, input switch, output fuse, EPO, SPD, leakage protection and insulation protection. It features our patented U-shaped air duct design, and can operate from -30℃ to 70℃ (power derating 5%/°C above 50℃) with less than 65 dB noise. These features ensure reliable, low-noise operation in various outdoor environments.

Versatile Deployment Scenarios
With a rated power of 600kW/800kW, each power cabinet can feed up to 12 charging plugs simultaneously. It can either deliver full power to a single plug or distribute power dynamically among multiple outputs. The power cabinet can be deployed in both single and parallel configurations. For example, up to 2 power cabinets can be paralleled to support megawatt charging site, co-distributing energy to multiple dispensers as a whole.

Combined with customized charging dispensers, our Power Cube solution is well-suited for various high power charging (HPC) applications:
1> Highway fast charging hubs requiring ultra-fast service for long-range EVs and long-distance EV travels
2> Public or private fleet depots serving electric buses, logistics vans, and heavy-duty trucks
3> Urban charging corridors where power density and space utilization are critical

Modular & Scalable Architecture
At the heart of the Power Cube is its modular architecture, allowing site operators to right-size charging power as demand increases or changes. Power capacity can be scaled by adjusting the number of power modules to match evolving load demands, ultimately lowering upfront investment while ensuring future-proof scalability and long-term flexibility.

In addition, by utilizing different types of power modules, it can not only serve as an HPC power source, but also adapt to other use cases such as BESS, V2G, AC micro grid or DC micro grid integrations. This is made possible by our G2 power module family, which are designed with identical dimensions. This standardized approach solves AC/DC, DC/DC, and bidirectional power conversion needs, serving from EV fast charging to battery energy storage and micro grid scenarios while streamlining installation, upgrades and maintenance.

Intelligent Power Switch Matrix
A key advantage of this Power Cube is its intelligent power switch matrix, which enables dynamic power sharing among multiple outputs. At the core of this functionality is a node-based architecture, where each group of power modules forms a “node” that corresponds to a charging output. What truly distinguishes is that all nodes collaborate in real time to scale power up or down based on actual charging demand. This creates a decentralized, self-adaptive mechanism for dynamic load management with outstanding features such as:
1> Dynamic power sharing in response to real-time charging demand
2> Optimized energy utilization by deallocating unused nodes
3> Intelligent pathfinding to prioritize idle and available nodes

Combined with intelligent load balancing and site energy management system (EMS), it can optimize power distribution, especially in high-traffic or energy-constrained environments. With our intelligent power switch matrix, it helps maximize energy utilization and operation efficiency for HPC charge point operators (CPOs).

In general, our Power Cube provides a future-proof, high-performance foundation for next-generation HPC infrastructure. Its modularity, scalability, and flexibility allow HPC site operators to deliver seamless fast-charging service with higher efficiency and lower operational complexity. This Power Cube’s compact footprint and power sharing strategy make it ideal for space-constrained HPC sites, and its modular design facilitates flexible expansion as demand grows.

Whether retrofitting existing infrastructure or building new HPC stations, this solution can maximize your operational efficiency and investment flexibility
