Flexible DC Charging Stack Power Sharing System
GOHO flexible charging stack — intelligent power distribution across multiple charging terminals. Available in 360kW, 480kW, and 720kW configurations. Maximize grid utilization, reduce infrastructure cost, and optimize charging efficiency for large-scale commercial stations and fleet depots.
Scalable Power Options
Three standard configurations to match your site capacity — easily expandable as your charging demand grows.
Compact Entry Model
Ideal for small commercial stations and medium-size fleets. Supports up to 6 charging terminals with flexible power distribution.
Standard Mid-Size
Balanced capacity for growing charging networks. Powers up to 8 terminals simultaneously with intelligent load management.
High-Capacity Flagship
Maximum throughput for highway hubs and large fleet depots. Delivers shared power to up to 12 charging terminals.
One Power Pool, Many Charging Points
Instead of each charger having its own dedicated power supply, the flexible charging stack creates a shared power pool that dynamically allocates energy where it's needed most.
Intelligent Power Allocation for Maximum Efficiency
Traditional charging stations waste capacity — each charger has a fixed power rating that sits idle when no vehicle is connected. Our flexible charging stack architecture eliminates this waste by pooling all available power into a central energy bank and distributing it dynamically across multiple charging terminals.
When only a few vehicles are charging, each receives maximum power for the fastest possible charge. As more vehicles connect, the system automatically balances the load across all active ports. This means higher utilization of your grid connection, lower infrastructure cost per port, and faster average charging times compared to traditional fixed-power installations.

Why Flexible Charging Stacks Outperform Traditional Chargers
Future-proof your charging infrastructure with intelligent power sharing.
Maximize Grid Utilization
Shared power pool means your grid capacity is always fully utilized. No more idle transformers and wasted electrical infrastructure investment.
Lower Cost Per Port
Shared power electronics reduce cost per charging terminal by up to 40% compared to equivalent standalone DC chargers.
800V Platform Ready
200-1000V DC wide output supports both 400V and 800V vehicles — future-proof for next-generation high-voltage EVs.
Fully Modular & Scalable
Start with 360kW and scale up to 720kW by adding power modules. Add more terminals at any time without electrical re-engineering.
N+1 Redundancy
Hot-swappable power modules with N+1 redundancy ensure the station keeps operating even if one module requires service.
Central Management
Single point of control for the entire charging facility. Monitor, manage, and update all terminals from one central console.

Frequently Asked Questions
Common questions about flexible charging stack technology. Want a custom design? Consult our engineering team.
A flexible charging stack (also called a "split charging system" or "power sharing system") is a centralized architecture where multiple charging terminals share a common pool of power modules. Instead of each DC charger having its own dedicated power electronics, the stack houses all power conversion modules in a central cabinet and distributes DC power to lightweight terminal units. This means much higher utilization of your grid capacity — when only one car is charging, it gets maximum power; when more cars connect, power is shared intelligently. The result: faster average charging, lower cost per port, and better return on investment.
Our flexible charging stack supports up to 12 charging terminals per system. The exact number depends on your chosen power pool size and desired power-per-terminal. For example, a 360kW stack could power 6 terminals at 60kW each, or 12 terminals sharing 30kW average. A 720kW stack could deliver 60kW to 12 terminals simultaneously. Our team will help you optimize the configuration based on your expected vehicle throughput patterns and site constraints.
Flexible charging stacks typically reduce total cost of ownership by 25-40% compared to equivalent standalone DC chargers. Savings come from: shared power electronics (lower hardware cost per port), simplified electrical installation (single grid connection instead of many), smaller transformer sizing (due to diversity factor), and reduced maintenance (centralized power modules). The larger your station, the greater the savings. We can provide a detailed cost comparison for your specific project.
Absolutely — that's one of the biggest advantages. You can start with a 360kW base configuration with just a few terminals, then add more power modules and charging terminals as demand grows. The modular design means expansion is straightforward and doesn't require replacing existing equipment. This "pay as you grow" approach significantly reduces upfront investment risk while ensuring you're ready for future EV adoption growth.
Our flexible charging stack supports OCPP 1.6J and OCPP 2.0, which are the global standard protocols for charging station management systems (CSMS). This means it's compatible with virtually every major CSMS platform on the market. We also offer MQTT and REST API interfaces for custom integrations. The system supports remote monitoring, firmware over-the-air updates, dynamic load management, tariff management, and all standard OCPP features.
The system features N+1 redundancy and hot-swappable power modules. If one module develops a fault, the system automatically redistributes the load across the remaining healthy modules — the station keeps operating at slightly reduced capacity. Failed modules can be replaced quickly without powering down the entire system. Our standard warranty covers module replacement, and we offer extended service level agreements (SLAs) for mission-critical installations that guarantee response times and uptime targets.
