ODM At Home EV Charger Factories & Supplier

An AC wallbox (such as our 7kW–22kW EV-ONE units) acts as an intelligent control and safety switch supplying alternating current directly to the vehicle's internal On-Board Charger (OBC). The charging speed is strictly capped by the vehicle’s OBC hardware (often 7.4kW single-phase or 11kW three-phase). In contrast, a 20kW–40kW compact DC charger bypasses the OBC completely, rectifying AC utility power to high-voltage DC (200V–1000V) within the external cabinet itself. This enables vehicles with modest internal AC converters to recharge up to 3x faster, unlocking commercial-grade turnaround speeds for fleet residences, high-end private villas, and commercial vehicle operators.

Our residential hardware integrates with external Current Transformers (CT clamps) or bidirectional smart energy meters installed at the main household distribution panel. Through RS485 Modbus or encrypted local Wi-Fi, the charger samples whole-home power draw in real-time (sub-second intervals). If high-draw appliances (HVAC, heat pumps, induction cooktops) activate, the charger automatically throttles its duty cycle and pilot signal current down, preventing main breaker trips. Once household loads subside, charging current ramps back to maximum rated capacity without manual intervention.

HizonSun chargers support OCPP 1.6-J (JSON over WebSockets) and are engineered for seamless upgrade paths to OCPP 2.0.1. Hardware control boards feature dual-core ARM processors running embedded Linux, with connectivity options spanning 4G LTE-M / NB-IoT, Wi-Fi 2.4/5GHz, and 10/100 Mbps Ethernet. We offer native cloud firmware enabling remote diagnostics, dynamic tariff reception, secure Over-The-Air (OTA) firmware deployments, white-labeled smart billing algorithms, and complete API integration into third-party Charge Point Management Systems (CPMS).

Electrical safety is engineered directly into our circuit designs. Every AC and DC unit incorporates integrated Type A + 6mA DC residual current detection (compliant with IEC 62955), eliminating the expensive requirement for external Type B RCD installations. In addition, our firmware executes active PEN conductor fault detection (essential for UK and Commonwealth PME earthing setups without needing auxiliary earth rods), over-voltage, under-voltage, surge suppression (Type 2 SPD), over-temperature monitoring at all gun terminal pins, and flame-retardant UL94-V0 polycarbonate or galvanized steel enclosures.

For standard ODM brand adaptations (custom silk-screened logos, custom exterior paint/casing colors, customized UI boot screens, and branded cardboard packaging), delivery timeframes range from 3 to 4 weeks. For ground-up mechanical housing designs or proprietary cosmetic injection molds, our in-house industrial engineering team provides 3D prototypes within 10 days, production tooling within 35 days, and pre-compliance certification samples within 60 days, backed by end-to-end laboratory audit support.
