China Commercial Electric Vehicle Charging Station Factory & Suppliers

An integrated DC charging pile houses both the AC-to-DC rectification power modules and the user dispensing terminal (cables, screen, billing) within a single self-contained enclosure. Integrated systems (typically 60kW to 240kW) are ideal for sites with 2 to 4 charging bays, such as retail parking, corporate offices, or small fuel stations. In contrast, a split-type system separates the noisy, high-voltage power conversion modules into a heavy-duty central power cabinet (360kW to 720kW) installed in a utility equipment area, which then feeds 8 to 12 compact satellite dispensing posts. This split architecture eliminates acoustic noise near drivers, allows full dynamic power matrixing, reduces ground-level footprint at the parking spaces, and dramatically lowers total cost of ownership (TCO) for high-throughput transit and logistics hubs.

Our proprietary internal matrix switching matrix operates via high-reliability contactor relays or solid-state silicon switches grouped into 20kW or 30kW module channels. When an EV initiates a session via CCS2, CCS1, or GB/T, the charger communicates with the vehicle's Battery Management System (BMS) through CAN or PLC to identify pack voltage (e.g., 400V legacy vs. 800V modern) and maximum allowable current. The central controller dynamically assigns the exact number of power modules needed to satisfy that vehicle's current demand curve. If a secondary vehicle arrives at another port, the system instantly recalculates and reassigns idle modules without dropping the charging session of the primary vehicle, maximizing energy transfer efficiency.

Yes. All commercial chargers come pre-loaded with an open-architecture OCPP 1.6-JSON stack (upgradeable to OCPP 2.0.1). We have validated interoperability with leading global Central Management Systems (CMS) including Driivz, AMPECO, ChargeLab, Greenlots, and customizable open-source backends. The controller supports WebSocket connections over TLS 1.3 encryption, client certificate authentication, remote start/stop, smart charging profile schedules, and automated alert telemetry. Additionally, we provide custom JSON API endpoints for enterprise fleet dispatch systems to automate charging schedules based on vehicle departure timetables.

In many prospective commercial locations—such as highway rest areas, rural delivery depots, or older commercial complexes—the local distribution grid transformer may only supply 50kVA to 100kVA of spare capacity. Installing a dual 120kW DC fast charger would trigger mandatory grid transformer upgrades that can cost over $80,000 and take 12 to 18 months in municipal permitting. Our 100kWh or 200kWh LFP battery integrated charging pile charges slowly from the existing weak grid during idle periods or absorbs on-site rooftop solar PV. When an EV plugs in, the battery discharges alongside the grid to deliver up to 180kW DC ultra-fast bursts, bypassing utility grid upgrade bottlenecks.

Our systems incorporate multiple redundant safety circuits: input overvoltage/undervoltage protection, output reverse-polarity diodes, insulation resistance monitoring (≥500V DC leakage test before contactor engagement), emergency stop circuits, lightning surge suppression (Type 2 SPD), and overtemperature derating. Thermally, our cabinets feature isolated air channels with variable-speed PWM centrifugal blowers that modulate RPM based on internal thermal sensor matrices. For extreme environments, optional liquid-glycol cooling circuits ensure that power modules remain below 65°C even during sustained 50°C ambient desert operations.

We provide a standard 24-month manufacturer warranty with optional extension up to 5 years. For international distributors and CPOs, we ship 2% to 3% critical maintenance spares (power modules, control boards, contactors, cable assemblies) directly with the initial container batch. Standard production lead times are 15 to 25 working days for standard configurations, and 30 to 45 working days for bespoke OEM sheet metal and custom branding orders. Our 36 global service partners ensure regional technical support and expedited replacement dispatch.
