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.
