Decarbonizing Global Transit Through Scale, Precision, and Modular Power Electronics
The global transition toward electrified transportation is experiencing an exponential shift from localized pilot deployments to nationwide high-power charging corridors. As battery chemistries advance toward 800V and 1000V Silicon Carbide (SiC) architectures, the demands placed on Electric Vehicle Supply Equipment (EVSE) manufacturers have surpassed conventional electrical assembly.
Operating from Kunshan, Jiangsu—China’s premier industrial engineering and electronics corridor—Suzhou HizonSun Tech Co., Ltd. stands as a benchmark high-tech manufacturer combining deep in-house power electronic research with high-volume industrialization. Our vertical supply chain integrates state-of-the-art power conversion modules, proprietary embedded firmware, smart cloud protocol compliance, and precision sheet-metal engineering.
By solving critical pain points such as high total cost of ownership (TCO), grid saturation constraints, and cross-border protocol fragmentation, we empower CPOs, highway concessionaires, bus fleet operators, and institutional EPC contractors to deploy resilient charging assets capable of 99.5%+ uptime across demanding environments.

Lowering Total Cost of Ownership (TCO) for Global Operators
Smart procurement looks beyond upfront hardware expenses. Discover how our modular engineering, high electrical efficiency, and direct factory lifecycle support maximize long-term asset profitability.
Capex Optimization
By eliminating middle-tier trading agencies and procuring directly from our Kunshan manufacturing line, institutional buyers achieve an immediate 25% to 40% capital savings per installed megawatt of charging capacity.
Minimizing Energy Parasitics
With class-leading 96.5%+ conversion efficiency and dynamic standby sleep routines, our DC charging piles dramatically curtail electrical waste, directly reducing monthly operating expenses paid to utility companies.
Hot-Swappable Maintenance
Mean Time to Repair (MTTR) is reduced to under 15 minutes. Our power converter cabinets utilize blind-mate hot-swappable sub-modules. Field technicians can isolate and replace modules without system de-energization.
Emerging Architectures Shaping Next-Gen Infrastructure
Stay ahead of industry obsolescence. HizonSun continually invests over 10% of gross revenue into cutting-edge power topologies, distributed microgrids, and bi-directional energy transfer.
Megawatt Charging System (MCS) & Liquid Cooling
Heavy commercial transport, e-buses, and electric mining haulers require megawatt-level power. HizonSun's ultra-high-power split systems support up to 720kW continuous delivery, integrating liquid-cooled terminal cables capable of 500A to 600A continuous charging without thermal throttling. Our intelligent coolant circuit actively monitors temperature, flow rate, and insulation resistance in real time.
Battery-Buffered Microgrids & Solar-Storage Coupling
Grid expansion delays often stall commercial charging projects. Our all-in-one 100kWh and 200kWh Lithium Iron Phosphate (LFP) energy storage charging piles solve this bottleneck. By buffering grid draw, shaving peak demand tariffs, and integrating directly with rooftop photovoltaic arrays, operators achieve rapid site commissioning even on fragile 30kVA transformers.

Frequently Asked Questions by Global B2B Buyers & EPCs
In-depth responses authored by our senior engineering and export compliance team to guide your project feasibility, tender submissions, and factory auditing.
What connector standards and regional vehicle compatibility do HizonSun chargers support?
HizonSun designs chargers to universal standards across all major international markets. Our production lines manufacture chargers conforming to European CCS2 and Type 2 (IEC 62196), North American CCS1, SAE J1772, and NACS (SAE J3400), Japanese CHAdeMO, and Chinese national GB/T 20234 standards.
Our multi-standard DC chargers can be ordered with mixed cable configurations (e.g., CCS2 + GB/T or CCS1 + NACS) to accommodate cross-border fleets or diverse import demographics across Southeast Asia, South America, and the Middle East.
How does HizonSun ensure communication interoperability with third-party OCPP backends?
All HizonSun smart AC wallboxes and DC fast charging stations implement native OCPP 1.6-JSON firmware and are fully architected for migration to OCPP 2.0.1. We maintain software copyrights for our proprietary embedded controller stack, which has been pre-validated against market-leading Charge Point Management Systems (CPMS) including AMPECO, Driivz, Monta, and GreenFlux.
Our units support secure remote transactions, automated firmware OTA (Over-The-Air) upgrades, remote diagnostics, smart charging load profiles, and automated reset commands, drastically reducing truck rolls and field service callouts.
What level of OEM/ODM customisation is available for corporate brands and CPOs?
As an authentic source manufacturer, we offer comprehensive white-label OEM and bespoke ODM development cycles. Our industrial design team customizes structural sheet metal, RAL powder-coat colors, branded vinyl fascias, and acrylic backlit logos.
At the electrical and software layer, we support custom screen user interfaces (UI), bespoke cable lengths up to 10 meters, integrated RFID card branding, payment POS terminal integration, and firmware-level adjustments to support proprietary private network protocols.
How does an integrated Energy Storage Charging Pile solve local grid bottlenecks?
Deploying high-power DC chargers often requires expensive utility transformer upgrades that can take 12 to 24 months to approve. Our 100kWh and 200kWh LFP Energy Storage Charging Piles overcome this obstacle by functioning as a bi-directional power reservoir.
The integrated battery system trickles energy from a low-capacity grid connection (or rooftop solar array) during periods of low activity or off-peak utility pricing. When an EV connects, the system discharges the battery in tandem with the grid to deliver ultra-fast charging (up to 160kW–240kW) without exceeding the site's contractual electrical capacity.
What is the typical production lead time and export warranty framework?
Standard AC wallbox orders ship within 10 to 15 business days. Integrated DC fast chargers (60kW to 240kW) generally require 20 to 30 calendar days depending on customization options and volume. Megawatt split-type systems and ESS charging piles carry an average lead time of 35 to 45 days.
We provide a standard 24-month comprehensive factory warranty on all EVSE hardware, with optional extensions up to 5 years. Warranty claims are serviced via our rapid spare parts dispatch network, supported by 36 global sales and service partner hubs across Europe, South America, North America, and Southeast Asia.
What electrical safety and surge protection architectures are embedded within the units?
Safety is the primary prerequisite of our engineering philosophy. Every HizonSun DC charging pile features over 15 embedded protection layers: input over-voltage, input under-voltage, output over-voltage, output short-circuit, over-current, over-temperature, reverse polarity, and emergency stop monitoring.
Furthermore, our units incorporate Type B residual current devices (RCD) capable of detecting 6mA smooth DC leakage currents, Type 2 AC/DC surge protection devices (SPD), continuous insulation impedance monitoring of the high-voltage bus, and connector temperature thermistors that throttle power output should pin temperatures exceed safe limits.
