The company’s mission is to deliver innovative, safe, and energy-efficient charging solutions that empower customers to embrace electric mobility while optimizing energy use and reducing costs.
The electric vehicle ecosystem operates on a matrix of international engineering standards. Electrification programs require rigorous knowledge of connector pin configurations, communication protocols, and electrical thresholds to assure safety and seamless integration with public and private utilities.
The European and global benchmark for AC charging. Supporting single-phase and three-phase power up to 22 kW, this connector features built-in signaling pins (Control Pilot and Proximity Pilot) to establish safety handshakes before current flows.
Integrating standard AC connectors with dedicated DC pins, CCS technology enables high-capacity fast charging up to 350 kW+. CCS2 is typical in Europe, whereas CCS1 remains standard across North American fleets.
Crucial for Asian and Latin American infrastructure, GB/T (Guobiao) governs physical connections and system safety protocols. In addition, the shift to NACS (SAE J3400) requires manufacturers to deliver adaptable connector configurations.
| Connector Standard | Primary Geographic Markets | Maximum Current / Voltage Specs | Communication Protocol | Ideal Application Use-Case |
|---|---|---|---|---|
| Type 2 (IEC 62196) | Europe, Australia, India, UK | 32A / 400V AC (Up to 22 kW) | PWM (Pulse Width Modulation) | Commercial office complexes & smart home integrations |
| CCS2 (Combo 2) | Europe, South America, Oceania | 500A / 1000V DC (Up to 350 kW+) | PLC (Powerline Comm. over DIN 70121 / ISO 15118) | Public highway fast-charging networks |
| GB/T (20234.2 / .3) | China, selected emerging markets | 250A / 1000V DC | 32A / 400V AC | CAN Bus (Controller Area Network) | Public municipal utility infrastructure |
| CHAdeMO | Japan, Legacy global networks | 400A / 1000V DC (Up to 400 kW) | CAN Bus protocol | Industrial site fleets and heritage utility depots |
Procuring EV infrastructure components from China, particularly from manufacturing hubs like Foshan, provides unparalleled strategic value. Our factories operate at the intersection of raw material access, precision tooling engineering, and automated assembly technology.
Our localized supply chains consolidate copper wire extrusion, raw thermoplastic polyurethane (TPU) compounding, silver-coated pin plating, and advanced PCB manufacturing in a highly localized radius. This compression results in direct cost reductions that we pass on to our B2B procurement partners.
Each design undergoes rigorous environmental chamber stress tests, including helium leak detection for IP65/IP67 integrity, mechanical cycling simulation, and high-voltage dielectric breakdown analysis. This ensures that every shipment aligns with CE, RoHS, and local regulatory criteria.
With our dedicated R&D engineering teams, we rapidly iterate on OEM/ODM requirements. Whether your system calls for custom sheet-metal designs, integrated RFID/NFC modules, or customized OCPP JSON integrations, our production lines adapt without delay.
Every deployment project demands a specialized architecture to accommodate physical limits, power availability, and commercial requirements. Walnut Charger designs systems specifically targeted to solve these challenges.
Fleet operations mandate high duty-cycle equipment. By utilizing our multi-gun DC charging piles (such as the Nancome 120kw systems) paired with dynamic load balancing, fleet managers optimize charging times during off-peak rate hours, preventing peak demand utility charges.
Public hardware must withstand vandalism, vehicle impacts, and extreme weather. Our street-side sheet metal EV charging boxes feature IK10 mechanical impact ratings and IP65 sealing, making them suitable for long-term municipal roadside deployment.
For residential parking, space and available grid current are constrained. Walnut’s ultra-slim 22kW AC wallboxes with integrated Smart App control and Dynamic Load Balancing (DLB) ensure multiple vehicles charge safely without overloading the building's electrical main.
The EV landscape is transforming. Navigating this evolution requires sourcing hardware designed for the standards of tomorrow. Key market transitions include:
Future architectures will treat vehicles as decentralized battery storage systems. Implementing ISO 15118 protocol stacks enables bidirectional energy transfer, allowing fleets and facilities to feed power back to local grids during peak pricing periods, creating a new revenue stream.
Proprietary networks lock operators into single-source vendors. Our hardware relies on open standard JSON web socket connectivity, facilitating seamless software integration with global billing systems, user authentication nodes, and cloud-based grid operators.
When sourcing commercial EV connectors and charging stations at scale, relying on low price point metrics is a major risk. Technical buyers must audit manufacturers against strict performance indicators:
High quality terminals utilize silver-plated copper alloys providing contact resistance below 0.5mΩ. Poor materials lead to heating issues, voltage drops, and premature terminal failure during continuous high-amperage usage.
Outdoor cables must use high-grade TPU (Thermoplastic Polyurethane) or TPE formulations. This ensures flexibility in sub-zero climates (-40°C) and protects against UV degradation, oil exposure, and mechanical crushing.
Robust configurations require built-in Type B RCD protection (AC 30mA + DC 6mA leak protection), over-temperature shutdown sensors inside the connector head, and over/under-voltage mitigation systems.
