OEM Home DC Fast Charging Suppliers & Supplier

Modern passenger EVs feature battery packs exceeding 80kWh to 130kWh. Standard AC chargers rely on the vehicle's restrictive on-board charger (typically 7kW–11kW), requiring 9 to 14 hours for a full charge. A 20kW–40kW DC charger bypasses the OBC, directly feeding the high-voltage pack to achieve an 80% state of charge in 45 to 90 minutes. This creates a compelling premium offering for luxury homeowners, executive fleets, multi-EV residences, and time-constrained commercial operators.

Commercial DC charging piles produce 65 to 75 dB(A) of high-frequency acoustic noise, which is unacceptable in private residential environments. HizonSun uses Silicon Carbide (SiC) power modules operating at switching frequencies up to 100kHz, allowing significantly smaller magnetic cores and dramatically lower heat loss. Combined with an isolated sealed airflow channel and smart PWM-governed low-RPM centrifugal fans, our home DC wallboxes maintain noise emissions below 48–50 dB(A) under full load.

In three-phase regions (Europe, Australia, Asia), a 20kW charger requires a 400V AC three-phase supply drawing approximately 32A per phase, and a 30kW unit draws roughly 48A per phase. In split-phase 208V/240V markets (North America), our specialized multi-module platforms can utilize parallel 240V lines or step-up isolation transformers, or pair directly with a battery-buffered energy storage system (BESS) to supply burst DC current without tripping standard 200A residential utility drop heads.

We provide full-scope white-label manufacturing: bespoke industrial sheet metal/die-cast aluminum enclosure styling, corporate brand silkscreening and powder coating (RAL color matching), customized touchscreen graphic user interfaces (UI), tailored cable lengths and connector configurations (CCS2, CCS1, NACS, GB/T), custom CAN-bus or Modbus communication integrations, and private-label firmware pre-configured to point to your proprietary OCPP cloud management backend.

Most commercial chargers pass only EN 55011 / EN 61000-6-4 (Class A: Industrial environments). Placing an industrial charger on a residential grid can cause severe electromagnetic interference with home networks, consumer audio, and home appliances. HizonSun engineers specialized multi-stage common-mode and differential-mode line filters, complete copper shielding, and software-driven spread-spectrum switching to meet strict EN 61000-6-3 / CISPR 22 Class B residential compliance.

Yes. Our DC hardware platforms can be specified with bidirectional SiC active front end (AFE) topologies supporting DIN SPEC 70121, ISO 15118-2, and the latest ISO 15118-20 bidirectional protocols. This allows our units to reverse power flow, drawing energy from the vehicle's high-voltage battery to support home loads during peak tariff events or utility outages, governed seamlessly via OCPP 2.0.1 smart energy profiles.

For standard branded catalog models, our MOQ starts at 5 units for distributor pilot validation. For fully customized OEM projects (including bespoke exterior tooling and proprietary firmware builds), MOQ is typically 50 to 100 units depending on complexity. Standard production lead time is 3 to 4 weeks from Kunshan factory dispatch, supported by streamlined ocean container loading and DDP logistics options.

All HizonSun chargers are covered by a standard 2-year industrial warranty (extendable to 5 years). We implement a modular Field Replacement Unit (FRU) philosophy: power modules, control boards, contactors, and display screens can be swapped out within 15 minutes by any certified local electrician without decommissioning the entire unit. We provide spare part kits with every batch order and support your field engineers via our 36 global service nodes.
