High-efficiency AC and DC solutions engineered for heavy-duty operational efficiency, municipal fleets, and high-frequency commercial charging points.
The transition to emission-free transport requires more than standard public infrastructure. Logistics fleets, heavy duty trucks, bus networks, and municipal service units demand dynamic power outputs, thermal control safety matrices, and rock-solid supply chain continuity.
For fleet operations and heavy-duty vehicles, charging systems must operate continuously. From high-capacity AC systems utilized in overnight bus depots to Megawatt Charging System (MCS) protocols, our hardware architecture ensures sustained efficiency levels exceeding 96.5%, minimizing thermal loss.
Equipped with standardized OCPP 1.6J and OCPP 2.0.1 integrations, heavy duty stations link directly to central management suites. Real-time dynamic load balancing protects local sub-grids from capacity overloads while enabling secure over-the-air (OTA) updates and billing integrations.

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.
Navigating the next frontier of high-power charging, grid alignment, and silicon carbide power electronics.
By transitioning from traditional IGBT modules to Silicon Carbide (SiC) MOSFET switchgears, our current-generation power conversion modules achieve lower thermal resistance, smaller physical footprints, and a significant boost in operational efficiency across varying load cycles.
High continuous currents generate extreme heat. Next-gen heavy-duty solutions utilize closed-loop liquid cooling systems running synthetic coolants through both the power modules and the charging cable/connector plug, ensuring continuous output without derating.
Heavy-duty fleets represent immense energy storage potential. Integration of vehicle-to-grid (V2G) capabilities allows municipal trucks and school bus fleets to discharge back into the grid during peak load hours, turning capital equipment into grid-balancing assets.
Tailored systemic layouts to overcome peak power challenges, logistical bottle-necks, and complex localized compliance hurdles.
Running multi-vehicle fleets demands rigorous routing and schedule-aligned charging. Our microgrid-ready heavy-duty solutions orchestrate fleet load optimization. System schedules charge cycles based on vehicle arrival times, State-of-Charge (SoC), and real-time utility rates to minimize peak demand charges.
Eliminate dependencies on over-burdened local substations. By coupling solar photovoltaic generation plants directly with battery storage solutions (BESS) and high-power charging cabinets, logistics hubs can generate, store, and deliver green power on-site, dropping charging overheads drastically.
Municipalities require highly reliable charging infrastructure. Through rugged structural builds designed to withstand severe weather (IP55/IP65 ingress ratings, IK10 impact protection), Walnut Charger's fleet solutions ensure municipal buses and service vehicles maintain continuous route operations.
Deploying advanced robotics, digitized Quality Management Systems (QMS), and scalable component sourcing to deliver highly competitive cost-to-performance ratios.
Operating out of Foshan, China's core electrical engineering corridor, Walnut Charger manages a deeply integrated supply network. This proximity allows immediate sourcing of high-grade copper busbars, flame-retardant enclosures, customized PCBA control modules, and premium insulation components. We pass these localized cost efficiencies and logistical savings directly to our global distribution network.
By using automated testing benches, every charger undergoes dynamic load simulation, high-pot isolation diagnostics, ground integrity testing, and environmental chamber cycling. This systematic verification ensures that from container loading to end-point site activation, failure rates remain practically zero.
Navigating global electrical safety regulations and software interoperability requirements.
Our global portfolio holds certifications including CE (EN 61851-1, EN 61851-23), UKCA, CB, RoHS, and FCC. These certifications guarantee that chargers meet local electrical codes and interface smoothly with public grids without generating EMI issues.
We supply diverse connectivity hardware to match local fleet vehicles: CCS Type 1 (North America), CCS Type 2 (Europe & Global), CHAdeMO, GB/T (Asia), and the emerging MCS standard for heavy-duty electric trucks.
We offer white-label and customized software firmware setups. Our engineering teams integrate local backend management platforms via OCPP protocols, enabling custom RFID access cards, mobile app tracking, and distinct user billing solutions.
Enterprise procurement professionals and site development engineers must evaluate several factors when planning charging infrastructure updates:
Select hardware equipped with dynamic load balancing. This matches grid capacity limits and avoids costly site transformer upgrades.
Specify active liquid-cooled designs for regions with high ambient temperatures to prevent output derating during operations.
Verify that chargers support open API interfaces and OCPP 1.6J or 2.0.1 for easy integration with existing telemetry and fleet systems.
Explore our range of heavy-duty, smart wallbox, and commercial power hubs designed for maximum efficiency.
