Engineered to meet the dynamic thermal conditions and robust technical codes of Southeast Michigan's industrial corridors.
As the historic "Motor City" reinvents itself as the premier hub of American software-defined mobility and electrification, Detroit’s logistics fleets, heavy industries, commercial transit systems, and public infrastructures are facing unprecedented regulatory and economic shifts. Transitioning heavy-duty transport corridors and regional hubs to zero-emission vehicle platforms requires high-volume, reliable grid infrastructure.
Detroit’s freezing winters demand robust thermal management systems within charging hardware to ensure continuous operation without power derating. Simultaneously, compliance with native utility incentives, such as DTE Energy’s Charging Forward program and state-wide grid modernization initiatives, demands highly flexible firmware control architectures. Our hardware integrates seamlessly with these local frameworks, utilizing intelligent load shifting to lower demand charges and maximize project ROI.
By establishing factory-direct supply chains from China's premier high-tech Industry 4.0 production facilities, we supply Detroit’s procurement engineers, electrical contractors, and real estate developers with Tier-1 charging infrastructure at highly optimized capital costs.

Engineered with Silicon Carbide (SiC) modules, liquid cooling systems, and flexible communication layers.
Our proprietary matrix-allocation algorithm automatically distributes power among charging ports based on real-time vehicle demand. By splitting and combining modules, fleet depots can charge up to 4 heavy-duty trucks simultaneously without grid overloads.
For units from 360kW up to 1080kW, we utilize advanced liquid-cooled systems that support continuous high-power output up to 500A per connector. This prevents thermal throttle issues during high-ambient summers or intense fast-charging cycles.
With native support for ISO 15118 "Plug & Charge" security handshakes, our equipment offers automated billing and vehicle authentication. The bi-directional charging capabilities lay the technical foundation for future Vehicle-to-Grid (V2G) applications.
From auto manufacturing hubs to long-haul logistics corridors, we provide customized power solutions.
Engineered for high-duty cycles. Ideal for municipal transit agencies, delivery trucks, and distribution centers operating in the Detroit Metropolitan Area, supporting rapid turnaround schedules and minimizing fleet downtime.
Ultra-fast DC chargers designed for installation along prime Michigan interstate routes (I-94, I-75, and I-96). Features modular power cabinets and dual-port configurations for high throughput and reliable uptime.
Premium AC and dynamic low-power DC chargers designed for retail parking garages, executive parking areas, and multi-family residential projects, supporting local property value growth and tenant requirements.
The reliability of a commercial DC charger lies in its electronic controller. Unlike typical assemblers, Fonsencharge has independent development capabilities for the charging master control board. This allows us to supply customized PCBA controllers for global charging networks and modify operational parameters directly in the firmware.
Through our system integration partner Greenvora, we provide end-to-end energy solutions. Greenvora coordinates scientific research, product design, precise manufacturing, global sales, and ongoing technical support into a cohesive package. Whether you require customized communication firmware for proprietary fleet management software or specialized enclosure designs, our ODM capabilities deliver robust results.
This vertical control over both the hardware controller and system assembly allows us to provide long-term software support, quick bug resolutions, and secure firmware updates, satisfying strict cybersecurity standards.

Our smart factory in China operates on advanced Industry 4.0 principles, employing high-precision pick-and-place lines, automated wave soldering, optical inspection (AOI), and environmental burn-in testing chambers. By sourcing top-tier local components (such as semiconductor modules, specialized contactors, and high-frequency transformers) and integrating them under strict QA protocols, we achieve a highly competitive balance of cost and performance.
This robust supply chain helps insulate our clients from components bottlenecks, ensuring dependable manufacturing schedules. For major projects in Detroit and across North America, our factory-direct model eliminates intermediate dealer markups, offering deep cost savings that can be reinvested into project installation and site preparation.
Every single charger undergoes full-load factory testing under simulated harsh environments before crating and global shipping, minimizing field commissioning errors.
Our manufacturing headquarters holds multiple certifications including DEKRA CB, CE, ISO9001, and AAA credit ratings, complying with strict regulatory audits worldwide.
Supported by 15 software copyrights and multiple utility, design, and invention patents, ensuring that all technology supplied is legally protected and compliant.
Select from our certified product line, featuring power capacities from 20kW to 1080kW to meet varied municipal and enterprise needs.
Operating fast-charging systems in Michigan requires engineering tailored to extreme seasonal shifts. In the winter, low temperatures reduce lithium-ion battery receptivity, which requires smart pre-heating protocols from the charger. Our DC fast-charging solutions feature dynamic charging profiles that adjust power based on temperature data from the vehicle BMS, protecting battery health while maximizing transfer speeds.
Additionally, our cabinets are rated for NEMA 3R / IP55 environments, ensuring protection against freezing rain, road salt spray, and high humidity. Our electrical components meet strict overcurrent, short-circuit, overvoltage, and ground-fault protection standards, helping pass local electrical inspection and permitting processes in Wayne County and surrounding areas.
We collaborate with local engineering companies and utility providers to simplify the integration of high-power hardware with existing grid transformers.
Our smart-metering firmware simplifies data logging for commercial charging rebates and demand-response programs.
Utility demand charges are calculated using your highest electricity usage over a short period. For instance, charging multiple vehicles at high power simultaneously can create sharp demand peaks. Our chargers mitigate this via local dynamic power sharing and scheduled grid dispatch, helping operators restrict maximum power draw during peak hours and limit monthly utility fees.
Extreme cold slows down battery chemical reactions, leading to lower charge acceptance. Our chargers integrate with vehicle BMS to support safe pre-conditioning profiles. The charger cabinet itself features built-in component heating and an insulated design, keeping internal electronic controls within their standard operating temperatures and ensuring reliable performance down to -30°C.
Our systems natively support OCPP 1.6J and OCPP 2.0.1 protocols. This allows you to connect the chargers with popular network management systems (such as ChargePoint, EVconnect, or customized proprietary fleet software) via secure 4G LTE, Ethernet, or local Wi-Fi connections.
Yes. Through our specialized R&D facility at Fonsencharge, we supply customized master control boards and complete system cabinetry. We offer customized branding, specific paint colors, tailored screen interfaces, and firmware configurations to align with your corporate branding and network requirements.
