ODM Electric Vehicle Recharge Stations Factory & Suppliers

As a vertically integrated manufacturer based in Kunshan, China, our ODM scope encompasses the complete engineering spectrum:

• Industrial Design & Sheet Metal Fabrication: Customized structural cabinet geometry, corrosion-resistant marine powder coatings (C5-M rated), corporate pantone brand livery, and anti-graffiti finishes.
• Electrical & Power Architecture: Bespoke modular power sizing from 20kW up to 720kW, incorporating custom contactor sequencing, integrated isolation transformers, and auxiliary power outputs (e.g., 24V DC / 230V AC service sockets).
• HMI & Payment Interfaces: Multi-lingual touchscreens from 7 inches to 32 inches, integrated POS credit card terminals (Nayax, PAX, Payter), RFID reader calibration, and custom Android/Linux UI shells.
• Firmware & Cloud Customization: Custom OCPP 1.6J and 2.0.1 extensions, customized error code tables, local fallback whitelists, and white-label mobile management applications.

Our outdoor EVSE hardware is engineered for uncompromised resilience in climates ranging from sub-zero Nordic regions (-35°C) to scorching Middle Eastern deserts (+55°C). We deploy a multi-layered environmental protection design:

• Dual-Chamber Heat Isolation: The sensitive electronic control board and communication units are hermetically sealed in an IP65 clean chamber, while the power modules reside in an isolated duct with forced-air or liquid cooling.
• Automated Internal Climate Control: Integrated low-wattage PTC heating elements prevent condensation in sub-zero or humid morning cycles, while variable-speed PWM fans modulate airflow based on internal temperature sensors.
• Corrosion Resistance: Heavy-gauge galvanized steel or aluminum alloy cabinets coated with electrostatic polyurethane powders tested against 1,000-hour salt spray exposure.

An Energy Storage Integrated Charging Station combines a high-voltage Lithium Iron Phosphate (LiFePO4) battery container (typically 100kWh or 200kWh) directly with DC fast charging power electronics. This resolves three massive enterprise pain points:

1. Overcoming Grid Capacity Bottlenecks: Sites restricted to 30kW or 50kW grid transformers can still deliver 160kW+ DC fast charging sessions by drawing peak power instantaneously from the battery buffer.
2. Eliminating Demand Charges: Commercial power tariffs often bill heavily for peak instantaneous kilowatt spikes. The onboard Battery Management System (BMS) shaves peak demand automatically.
3. Time-of-Use (TOU) Arbitrage: The system charges its internal batteries during low-cost overnight off-peak periods or harvests on-site solar PV generation, dispensing stored clean energy to vehicles during peak tariff hours.

All our smart AC wallboxes and DC charging piles feature fully compliant OCPP 1.6-JSON and OCPP 2.0.1 client stacks. We maintain proven integration track records with major global Central Management Systems (CMS) including ChargePoint, ViriCiti, AMPECO, Driivz, Greenlots, and open-source platforms like SteVe. We provide full WebSocket protocol logs, remote diagnostics profiles, over-the-air (OTA) firmware upgrade hooks, and pre-configuration of TLS client certificates directly on the factory assembly line before shipping.

Every production batch undergoes a rigorous 100% full-load quality assurance process inside our Kunshan test facility:

• Dielectric Withstand & Insulation Resistance: Automated hi-pot testing at 2,500V AC to confirm galvanic barrier safety.
• Full-Load Thermal Burn-In: Continuous 4 to 8-hour testing at rated kilowatt capacity using programmable regenerative DC electronic loads.
• Protocol Interoperability Simulation: Validation with specialized ComEngine simulators testing CAN bus (GB/T), PLC/HomePlug Green PHY (CCS1/CCS2), and PWM signaling (Type 2 / Type 1).
• Safety Interlock Verification: Validation of emergency stop latency (<20ms), insulation monitoring device (IMD) trip thresholds, and ground fault circuit interrupt (GFCI) tripping times.

Standard OEM/ODM production lead times range between 3 to 4 weeks for standard catalog configurations and 6 to 8 weeks for custom sheet metal tooling and specialized component integration. We offer standard 24 to 36-month factory warranties, extendable up to 5 years via comprehensive service-level agreements (SLAs). Our modular architecture guarantees that power modules, control boards, metering modules, and contactors are modular field-replaceable units (FRUs), backed by dedicated overseas replacement parts consignments.
