A call to hardware manufacturers.
Charging Equipment & Manufacturing
Mobile DC fast charging needs new equipment designed for real-world service. rohm is the marketplace where manufacturers, engineers, and founding teams can bring that hardware closer to the operators and customers who need it.
Battery. Power. Cooling.
Controls. Vehicle. One unit.
A mobile DC fast charger brings together energy storage, power conversion, thermal management, control electronics, cabling, enclosure, and vehicle integration — all working as one deployable product. Different providers will configure that product differently depending on service area, customer base, and operating model.
The marketplace does not prescribe one design. It rewards hardware that performs in the field and stays in service.
Vehicle & form factor
The charger, the vehicle, and the operator workflow are one product. Form factor shapes the service model.
Battery system
Chemistry, capacity, packaging, recharge path, and replacement strategy define what the unit can do per shift.
Battery management system
Cell balancing, thermal monitoring, protection logic, and fault response. The BMS turns a pack into a managed asset.
Power delivery
Vehicle-compatible DC output, safely and repeatedly, across varying architectures and conditions.
Cooling system
Thermal performance determines whether the unit lasts a shift or derates halfway through. Coolant, airflow, and weather all factor.
Connectors & cabling
Connector mix, cable reach, weight, ergonomics, and replaceability. This is handled equipment in daily use.
Controls, data & telemetry
Charging logic, diagnostics, firmware, session data, and platform connectivity. Clean telemetry makes hardware visible and dispatchable on the marketplace.
Safety & serviceability
Safe, insurable, weather-rated, inspectable, field-repairable. Compliance opens the market. Serviceability keeps you in it.
Closer to the work,
faster to improve.
Listed hardware carries a Designed-in-the-U.S. score — a single number that reflects the domestic share of parts value and domestic share of assembly. It travels with the unit on the marketplace.
The reasoning is operational. Providers need parts, repairs, support, and new units on short timelines. The closer the hardware is made to where operators are using it, the tighter everything gets. Freight. Lead times. Repair loops. The speed at which field feedback reaches engineering.
Manufacturers who improve domestic sourcing or move assembly closer to operators see their position move. Operators and customers can reward it directly. A better supply chain becomes a commercial advantage.
Better hardware,
closer to the work.
Three paths onto
the marketplace.
Direct referral
The manufacturer owns the sale. rohm surfaces the hardware and routes qualified interest directly.
Facilitated
rohm helps coordinate the conversation, the agreement, and the operator fit on the manufacturer's behalf.
Distribution support
For hardware that needs to reach providers in specific markets. rohm helps connect equipment to the operators deploying it.
The hardware side
of mobile charging.
Established manufacturers
Charging hardware already in production, looking for a commercial channel into mobile service.
Hardware startups
Early units or prototypes that need a market to design toward and demand to pull them into production.
Engineers & component teams
Battery, thermal, power electronics, controls, and enclosure teams whose work belongs inside better mobile units.
Founders entering the space
Builders who see that mobile charging needs purpose-built equipment, not just adapted fixed infrastructure.
Build the equipment.
We got the marketplace.
Operators need hardware that holds up in the field, and customers need supply they can count on. We want to hear from the teams who can build it.
