ODM Separated Charging Pile Supplier & Manufacturer

Next-Generation Split-Architecture Fast Charging Systems: Dynamic Matrix Power Distribution, Megawatt Depots, and Global Turnkey Engineering Solutions.

Architectural Paradigm Shift

The Engineering Logic of Separated Charging Pile Architecture

As electric commercial vehicles, heavy duty e-trucks, and 800V passenger EVs flood the global transportation network, legacy "all-in-one" standalone DC fast chargers face fatal systemic limits. The separated charging pile architecture—commonly known as split-type or distributed DC fast charging systems—decouples heavy power conversion from parking bay user dispensers.

Centralized Power Rectification

Houses silicon carbide (SiC) or IGBT conversion stacks inside a weather-isolated, sound-damped utility cabinet located up to 100 meters away from vehicle bays. Minimizes noise, thermal stress, and physical footprint near parking bays.

Dynamic Power Pooling

Replaces rigid power assignments with dynamic matrix crossbar contactor routing. Automatically shifts 20kW/30kW/40kW modular power granular increments in real time, matching individual battery acceptance curves across up to 12 charging bays.

Ergonomic Ultra-Slim User Terminals

User dispensers carry zero bulky power electronics—only metering, liquid-cooled or boost-rated cable harnesses, and human-machine interface (HMI) screens. Yields compact parking footprints with ADA and CE ergonomics.

Enterprise Procurement Economics

Global Enterprise Procurement: Capex, Opex & TCO Analysis

For Charge Point Operators (CPOs), fleet logistics yards, heavy transit depots, and energy conglomerates, evaluating separated charging pile infrastructure requires a total cost of ownership (TCO) methodology that balances substation capacity constraints, grid connection penalties, and operational lifecycles.

Upgradeability (800V/Megawatt) Complete teardown and hardware scrap required Modular swap of rectifier racks and liquid-cooled terminal cables 10-Year Lifecycle Longevity

Optimizing Megawatt-Scale Grid Tariffs

Industrial power tariffs severely penalize instantaneous peak demand spikes. Separated charging pile systems integrate integrated software governors that cap aggregate power draw under utility-negotiated ceilings while dynamically balancing output across vehicle queues, saving thousands in monthly demand penalties.

Decoupled Maintenance Lifecycle

Dispensers exposed to harsh weather, public tampering, and physical fender-benders contain zero sensitive high-frequency power boards. When mechanical repairs occur, the master power cabinet remains online, powering adjacent charging bays without interruption.

Macro Sector Deployments

Specialized Applications Across Mission-Critical Verticals

Turnkey split-architecture topologies custom-engineered to overcome grid limits and high-turnover duty cycles across heavy transit, highway corridors, port logistics, and commercial complexes.

Municipal Bus & Transit Depots

Overnight trickle-fast charging for 40 to 100 electric buses. A centralized 480kW–720kW split power matrix dispenses low, continuous 40kW power to dozens of parked vehicles simultaneously, switching to high-power 300kW boost top-ups during short driver layovers.

Heavy-Duty Logistics & Port Hubs

Class 8 commercial electric semi-trucks demand high energy throughput. Our split architecture powers dual-liquid-cooled dispensers supporting continuous 500A–600A output, delivering 300km of driving range within a mandatory 30-minute cargo transshipment window.

Highway Supercharging Plazas

Interstate rest stops face extreme utilization variance—from idle mid-day hours to massive weekend holiday queues. Separated charging pile systems allow dynamic pooling where single 800V vehicles draw maximum 360kW-480kW power while adjacent cars share remaining rectifiers.

Engineering & Tender FAQ

Frequently Asked Questions by Technical Procurement Teams

Direct technical answers addressing power matrixing, cabling distances, reliability, and customization options from our chief hardware engineers.

What is the maximum permissible distance between the power cabinet and charging dispensers?
Our standard split-type power routing topology accommodates DC bus cable runs of up to 100 meters (328 feet) with less than 0.8% voltage drop when using correctly sized copper or aluminum underground conductors (typically 185mm² or 240mm² depending on current rating). The system incorporates active cable-drop compensation algorithms within the cabinet firmware that read real-time terminal voltage feedback via CAN bus or RS-485, automatically adjusting output voltage at the rectifier terminals to ensure exact target voltage reaches the vehicle battery terminals.
How does the dynamic matrix power allocation perform when multiple EVs arrive simultaneously?
Our central controller utilizes a proprietary matrix switching algorithm with high-durability DC contactors arranged in a crossbar matrix. Power is modularized in 30kW or 40kW rectifier blocks. When a vehicle initiates charging, the BMS handshake determines the maximum instantaneous acceptance power. As the primary vehicle completes its high-current bulk phase (e.g., transitioning from 10% to 70% SOC) and battery current tapers down, the central matrix dynamically reallocates surplus 30kW/40kW modules to newly arrived vehicles within 100 milliseconds without interrupting active sessions.
Can a 480kW or 720kW master cabinet support liquid-cooled dispensers?
Yes. The master power cabinet is fully compatible with both conventional air-cooled dispensers (up to 250A continuous) and high-power liquid-cooled user dispensers (up to 500A–600A continuous). In liquid-cooled configurations, the closed-loop chiller and glycol coolant pump unit can either be housed directly inside a dedicated auxiliary compartment of the user terminal or centralized at the main power cabinet, ensuring lightweight, flexible dispenser cables that drivers of any physical strength can easily maneuver.
What level of white-label ODM customization does HizonSun provide for CPO branding?
We offer end-to-end industrial customization. This includes custom sheet-metal exterior profiles, bespoke corporate RAL powder coat finishes, laser-cut backlit corporate logos, customized cable retraction mechanisms, integrated advertising lightboxes or digital LCD screens (up to 32 inches), customized touch HMI user interfaces, custom firmware branding, and pre-integrated localized credit card payment terminals (Nayax, Ingenico, Payter) configured for your regional banking merchant providers.
How does the system ensure resilience against individual power module failures?
Our systems utilize an N+1 modular redundancy architecture. Every 30kW/40kW charging module operates on an autonomous CAN sub-bus. If an internal rectifier module encounters an over-temperature, over-voltage, or semiconductor fault, the central supervisory controller instantly isolates the faulty module within 20 milliseconds without shutting down the charging bay. The dispenser continues operating with the remaining power pool while an alert is automatically dispatched to your OCPP cloud network. Faulty modules can be hot-swapped by field technicians in under five minutes.
