Engineered for instant deployment across commercial real estate, highway toll concessions, and industrial corridors facing medium-voltage substation expansion delays.
Decoupling high-power DC fast charging demand from regional medium-voltage grid constraints through localized battery storage buffer systems across Hanoi, Da Nang, and Ho Chi Minh City.
The Socialist Republic of Vietnam is experiencing an unprecedented inflection point in transport electrification. Propelled by national commitments under the Power Development Plan 8 (PDP8) and the Prime Minister's Directive to transition taxi fleets, public buses, and commercial logistics to 100% green energy by 2050, demand for DC rapid charging infrastructure has outpaced EVN's (Vietnam Electricity) immediate sub-transmission transformer upgrade schedules.
Key industrial centers such as Bac Ninh, Hai Phong, Binh Duong, and Dong Nai are experiencing acute peak demand surcharges. Expanding grid capacity to support conventional 180kW to 360kW DC charging piles often demands costly 22kV transformer installations, civil approvals exceeding 9 to 14 months, and hefty peak-hour capacity penalties.
The Strategic Solution: HizonSun’s ODM Energy Storage Integrated Charging Piles integrate Tier-1 Lithium Iron Phosphate (LiFePO4 / LFP) battery energy storage systems (BESS) directly inside or adjacent to the charger cabinet. By drawing a constant, low-rate AC feed (e.g., 30kW–50kW) during off-peak hours, the integrated system discharges at up to 240kW–400kW DC during vehicle charging, eliminating demand spikes and providing true microgrid resilience against seasonal brownouts.
High-efficiency bidirectional AC/DC converter topologies, dynamic DC-bus pooling, and multi-tier battery safety systems tailored for Southeast Asia’s extreme heat and humidity.
Our integrated storage chargers utilize an innovative shared DC-bus topology. Solar PV strings (MPPT), energy storage battery racks, and dual CCS2 charging guns interface along a shared 750V–1000V DC bus. This reduces round-trip conversion losses from grid-to-battery-to-vehicle by over 7.5% compared to conventional AC-coupled solutions.
Equipped exclusively with automotive-grade prismatic LiFePO4 cells from CATL or EVE. Every cabinet includes three-level Battery Management Systems (BMS) with cell-level voltage, impedance, and multi-point temperature detection, backed by pack-level aerosol fire suppression conforming to NFPA 855 and UL 9540A testing frameworks.
Native integration with standard Charging Station Management Systems (CSMS) via OCPP 1.6J and OCPP 2.0.1. Hardware supports ISO 15118-2/20 Plug & Charge and bidirectional V2G (Vehicle-to-Grid) protocols, allowing operators to monetize fleet batteries for regional ancillary grid frequency regulation.

Combining world-class power electronic production with rapid customization workflows to satisfy Vietnamese EPC contractors and international procurement mandates.
Headquartered in Kunshan, Jiangsu Province—at the beating heart of the Yangtze River Delta high-tech electronics cluster—Suzhou HizonSun Tech Co., Ltd. controls 100% of the manufacturing and testing lifecycle. With an annual output capability surpassing 500,000 charging and energy storage units, our production lines deploy automated SMT PCB assembly, robotized laser welding for battery busbars, and 100% full-load burn-in testing chambers.
The ODM/OEM Competitive Advantage for Vietnam:
Overcoming high ambient humidity, torrential monsoon rain, and remote grid dropouts with ruggedized, battery-buffered DC fast charging architecture.
Global semiconductor and electronics manufacturers operating in Northern Vietnam require turnkey fleet decarbonization without tripping corporate factory power quotas. HizonSun BESS charging piles charge from rooftop solar panels during daytime production shifts, powering electric logistics trucks and employee shuttles during evening shift turnarounds.
Long-distance interprovincial expressways connecting Hanoi to Can Tho frequently traverse rural areas where EVN transmission lines cannot support multiple simultaneous 240kW fast charges. Battery-buffered charging piles maintain constant 180kW+ dual-gun output for tourist and passenger vehicles without requiring substation upgrades.
Marine environments require rigorous IP55/IP65 ratings, dehumidification heating strips, and C5-M multi-stage powder coatings to neutralize tropical salt-spray fog. Eco-resorts integrate 100kWh–200kWh ESS chargers with localized microgrids to provide clean, silent EV charging powered by island renewable generation.
Evaluating Capital Expenditure (CAPEX) vs. Operational Expenditure (OPEX) in emerging Asian markets through smart peak shaving and avoided grid connection upgrades.
For fleet operators and CPOs in Vietnam, the true cost of an EV charging station extends far beyond the price of the charger itself. Traditional high-power charging incurs substantial hidden costs:
BESS Integrated ROI: By shaving peaks, shifting load to off-peak tariff periods ($0.04/kWh vs $0.14/kWh), and avoiding transformer civil works, a HizonSun 100kWh/160kW integrated storage pile consistently achieves payback in 2.8 to 3.4 years in Vietnamese commercial environments.

Comprehensive engineering insights for EPC project managers, municipal operators, and EV distributors navigating Vietnam’s charging rollout.
Our systems incorporate an active power conditioning subsystem (PCS) with wide input voltage tolerance (380V ± 20%) and automatic frequency regulation (50Hz ± 2.5Hz). When the local EVN line voltage drops or sags during peak regional demand, the internal battery storage instantly injects DC power to stabilize output, shielding connected electric vehicles from damaging surges, undervoltage faults, or unexpected charging aborts.
Yes. HizonSun’s energy storage charging piles support both grid-tied peak-shaving and seamless islanding microgrid modes. In the event of a total municipal power outage, the onboard Energy Management System (EMS) activates microgrid mode within 20 milliseconds, utilizing stored LFP energy and coupled rooftop solar to maintain continuous charging operations for critical logistics and emergency fleets.
Safety is built with four redundant tiers: (1) Inherent thermal stability of LiFePO4 chemistry with zero runaway risk up to 270°C; (2) Multi-sensor cell-level telemetry measuring carbon monoxide (CO), hydrogen (H2), smoke, and thermal escalation; (3) Pack-level aerosol fire extinguishing canisters that extinguish thermal hazards in under 5 seconds; and (4) External emergency stop relays and mechanical pressure vents certified under UL 9540A and NFPA 855 guidelines.
Utilizing high-grade CATL/EVE prismatic cells coupled with our closed-loop liquid cooling system, the battery pack maintains an optimal core operating range of 25°C ± 3°C even when ambient outdoor temperatures reach 42°C with 95% relative humidity. Under standard 1C discharge/0.5C charge cycling, the cells deliver over 6,000 complete cycles to 80% State of Health (SOH), equating to 10–12 years of reliable daily peak-shaving duty.
Our systems run custom OCPP 1.6 JSON / 2.0.1 firmware that easily interfaces with Vietnamese charging operator networks, cloud backends, and telematics systems. In addition to standard RFID cards and Plug & Charge, the hardware supports outdoor 10-inch or 32-inch touchscreen interfaces capable of displaying local dynamic VietQR codes, MoMo, ZaloPay, and VNPay merchant gateways.
