Global Commercial & Industrial Status of Split-Type EV Charging
As electric commercial fleets transition from passenger-car-scale charging to multi-megawatt operational requirements, conventional standalone all-in-one charging kiosks encounter severe engineering bottlenecks. The modern charging landscape demands a decoupled architecture: centralized high-voltage rectification combined with decentralized user satellite dispensers.
Overcoming Grid Utilization Traps
Traditional standalone chargers lock dedicated power modules into individual bays. When an EV reaches its constant-voltage saturation taper (80%+ SoC), upstream module capacity is stranded. Split-type matrix architecture aggregates all rectifiers into a shared dynamic pool, dispatching kilowatt increments to other active charging bays in real-time.
Optimized Civil Footprint & Safety
Isolating the massive 10kV step-down transformer and high-capacity AC/DC power cabinet away from vehicle traffic strips away footprint restrictions at the parking stall. Slim, noise-free dispenser pedestals maximize driver accessibility while eliminating high-voltage AC cabling near public transit platforms.
Substantial CAPEX & OPEX Reduction
By eliminating individual transformer drops, duplicated internal switchgear, and multi-cabinet cooling loops, enterprise fleet operators realize up to a 34% reduction in balance-of-system (BOS) capital costs. Centralized liquid or forced-air cooling modules reduce site maintenance down to a single service bay.
Dynamic Matrix Power Pooling: Technical Topology
A modern split-type charging system separates electrical power conversion from physical dispensing. The power stack comprises an array of 30kW or 40kW wide-voltage range (150V–1000V DC) power modules, bridged to dispensers via a solid-state or contactor-switched DC crossbar matrix.
1. Central Rectifier Power Enclosure (The Core)
The centralized power container interfaces with the medium-to-low voltage AC grid (380V/400V/480V 3-phase). It houses input isolation, lightning surge arresters (Type 1+2), active power factor correction (PFC > 0.99), and modular hot-swappable converter blocks.
- Silicon Carbide (SiC) Topologies: Delivers high-frequency soft-switching with efficiency curves exceeding 96.5% under 40%–95% load profiles.
- Thermal Isolation Zones: Independent air duct channels with IP54 outdoor sealing protect sensitive control electronics from harsh ambient dust and corrosive coastal air.
- Autonomous Matrix Controller: A localized high-speed DSP microcontroller executes allocation algorithms every 10 milliseconds, adjusting DC bus bar relays to deliver custom voltage/current envelopes per vehicle BMS request.
2. Satellite Dispenser Terminals (The User Interface)
Dispensers function purely as human-machine interfaces and high-power delivery conduits. Devoid of heavy rectifiers and noisy blower fans, dispensers can be installed flush against barriers, transit curbs, or structural columns.
- Dual-Protocol Charging Guns: Configurable with natural-cooled cables (up to 250A continuous) or active liquid-cooled CCS2 / NACS cables supporting up to 600A continuous boost.
- Comprehensive User HMI: High-bright 7-inch to 10-inch sunlight-readable touchscreens, integrated ISO 14443 RFID readers, EMV POS contactless credit card terminals, and dynamic LED status ring indicators.
- Autonomous Safety Relays: Dual-channel insulation monitoring devices (IMD), residual current detectors (RCD Type B), and emergency shutdown interlocks tied directly into the master cabinet loop.

Industry Solutions: Macro-Engineering Blueprint
Tailored technical implementations across global commercial transport, municipal infrastructure, and private enterprise networks.
1. Highway Corridors & Supercharging Plazas
Highway rest stops face extreme utilization spikes followed by calm troughs. A 720kW split-type system feeding 8 to 12 charging pedestals allows ultra-fast 350kW liquid-cooled charging for high-end 800V EVs when traffic is rapid, while smoothly distributing 60kW–90kW trickle top-ups across all vehicles during holiday peak gridlocks.
2. Electric Transit Bus & Logistics Depots
Municipal bus fleets return to central yards between 22:00 and 05:00. The split-type central cabinet provides sequential overnight trickle charging (30–45kW per bus across 12 dispensers) maximizing battery cathode longevity. During daytime route turnarounds, the same system converges full 360kW–480kW power into 2 designated rapid-turn stalls.
3. Weak Grid Microgrids with BESS Coupling
In remote logistics transit stops or areas with constrained distribution feeders, the split-type power bank integrates seamlessly with 100kWh–200kWh lithium iron phosphate (LFP) energy storage units and on-site solar arrays. The system buffers off-peak generation, preventing costly utility demand surcharges.

Frequently Asked Technical Questions (FAQ)
In-depth technical guidance written by senior power electronics engineers for EPC contractors, CPOs, and fleet infrastructure procurement managers.
Our centralized system incorporates a high-speed matrix switching backplane. When an EV connects to a dispenser, it communicates its charge curve parameters and instantaneous maximum current demand via ISO 15118 or GB/T protocols. The central DSP controller dynamically groups 30kW or 40kW power converter modules to form dedicated sub-bus lines matching that exact demand. When the vehicle reaches constant-voltage taper, the matrix seamlessly decouples surplus modules and routes them to adjacent vehicles, eliminating power wastage without dropping active charging sessions.
Standard installations comfortably support cable runs up to 50–80 meters between the central power cabinet and dispenser pedestals using correctly calculated copper or aluminum DC feeder cables. With proper voltage-drop compensation circuitry embedded within our dispenser terminal controllers, distances up to 120 meters can be engineered. This flexibility allows operators to place the noisy, heavy power cabinet in an out-of-sight utility perimeter while positioning sleek dispensers right at prime parking bays.
HizonSun split-type stations are manufactured to IEC 61851-1, IEC 61851-23, IEC 61851-24, EN 61000 EMC directives, and UL 2202. Dispensers can be fitted with any combination of IEC Type 2 CCS (CCS2), North American CCS1, Tesla/NACS (SAE J3400), GB/T 20234, and CHAdeMO connectors. Furthermore, full OCPP 1.6J and OCPP 2.0.1 compliance ensures effortless integration into any third-party global billing, clearinghouse, and CPO platform.
In standalone all-in-one charging stations, an inverter failure or cooling malfunction frequently knocks the entire station out of service. In HizonSun split-type power banks, modules operate in an N+1 redundant parallel topology. If an individual 40kW module encounters an over-temperature or DC ripple fault, the system autonomously isolates that specific module, alarms the NOC cloud, and redistributes load across healthy modules. Charging operations at the satellite terminals continue uninterrupted.
Yes. Our modular power cabinets feature optional common DC bus coupling architectures. This allows on-site solar photovoltaic DC/DC converters and high-capacity Lithium Iron Phosphate (LFP) energy storage battery racks (100kWh/200kWh) to connect directly into the internal DC link. By avoiding repeated DC-to-AC and AC-to-DC conversion cycles, round-trip efficiency increases by 6%–8%, and reliance on weak local grid substations is greatly alleviated.
