    Case: A mobile field-energy unit for battery charging racks used in large-scale agricultural drone operations. Challenge: Remote fields may lack stable high-power electricity. When several spraying drones operate together, battery transport and charging can interrupt the spraying cycle. Solution: Deploy the Door Energy MCP-A in a field service area and use the correct industrial power interface to supply manufacturer-approved multi-bay battery charging racks. Key Features: Field energy supply: Reduce battery transport to a distant fixed power source. Multi-bay support: Configure output for the number and power of simultaneous chargers. Mobile deployment: Move the trailer as spraying shifts between fields. Safe compatibility: Use approved chargers; never connect an EV plug directly to a drone battery. Duty-cycle planning: Match storage to battery count, rotation time and daily spraying hours. Impact: Create a steadier battery-rotation cycle near the field, reduce drone waiting time and support longer operating windows in remote areas.
    Case: A mobile charging unit for roadside assistance to stranded electric vehicles. Challenge: A depleted EV may be far from a fixed charging station. Conventional towing can be time-consuming and expensive when the vehicle only needs enough energy to reach a safe destination. Solution: Send a Door Energy trailer-mounted or vehicle-mounted system to the vehicle, then provide a controlled amount of energy so it can reach a safe location or fixed charging station. Key Features: Rapid response: Bring charging capability directly to the vehicle location. Flexible configuration: Choose a trailer or vehicle-mounted platform for the service model. Connector compatibility: Configure CCS1 or CCS2 for the target vehicle mix. Safe deployment: Use warning lights, cones and a defined roadside procedure. Energy planning: Plan for safe onward range rather than a routine full charge. Impact: Give recovery operators another response option when towing is unnecessary, helping stranded vehicles resume their journey sooner after a controlled energy transfer.
    Case:  An MCP-D autonomous mobile charging unit for flexible charging across parking bays. Challenge: Installing high-power electrical infrastructure at every bay is expensive, while charging demand shifts between areas and time periods. Solution: Deploy the Door Energy MCP-D with 105kWh energy storage and up to 100kW output. The unit moves within the facility and delivers energy to parked vehicles instead of reserving every charging service for a fixed charger. Key Features: Autonomous movement: Designed to navigate constrained parking environments. Task scheduling: Move between bays according to charging requests. Charging output: Provide up to 100kW charging output. Energy storage: 105kWh reduces dependence on a fixed high-power feed at every bay. Facility fit: Assess ramps, turns, pedestrian routes and the return-to-charge point. Impact: Use limited electrical capacity and parking space more effectively, especially where a large-scale distribution upgrade is difficult or demand changes throughout the day.
    Case: A mobile energy storage and charging unit for electric airport ground support equipment. Challenge: Electric baggage tractors, belt loaders and other GSE work in short, concentrated turnaround windows. Fixed chargers may be far from the active stand or temporarily unavailable. Solution: Position the Door Energy MCP-E in an approved GSE service area. Its 420kWh energy storage and multiple outputs can support compatible electric GSE according to the turnaround schedule. Key Features: Large energy reserve: 420kWh supports concentrated operating windows. Multi-equipment support: Allocate energy across compatible GSE according to priority. Mobile deployment: Reposition the unit as stands and service areas change. Dynamic power allocation: Schedule charging around vehicle priority and turnaround time. Operational safety: Keep charging separate from aircraft movement and baggage routes. Impact: Add flexible charging capacity during phased electrification, seasonal peaks, stand changes or fixed-charger maintenance, while keeping GSE closer to the operating area.
    Case: A mobile energy storage and charging unit for electric port and terminal equipment. Challenge: Charging demand for terminal tractors and service vehicles changes with vessel calls, yard activity and vehicle routes, so fixed chargers cannot cover every operating zone efficiently. Solution: Use the Door Energy MCP-E as a movable 420kWh energy buffer near current demand. Charging can be scheduled by departure time, state of charge and operational role. Key Features: Large energy reserve: 420kWh supports high-demand operating periods. Multi-vehicle charging: Schedule charging for several compatible vehicles. Flexible relocation: Move between terminal zones as operations change. Environmental adaptation: Specify corrosion protection and maintenance for coastal use. Protected deployment: Position outside traffic lanes with suitable impact protection. Impact: Support phased charging-infrastructure construction and provide supplemental capacity during temporary peaks or fixed-station outages.
    Case: A mobile battery energy storage and charging unit for electric construction machinery. Challenge: Work zones change as a project progresses, so fixed chargers cannot always reach active equipment. Site power may also be insufficient for several machines charging at the same time. Solution: Deploy the Door Energy MCP-A near excavators, loaders and site vehicles. The trailer combines 210kWh energy storage with up to 180kW DC output and can be relocated as the project moves. Key Features: High-power charging: Up to 180kW from one connector, or two 90kW outputs. Energy storage: 210kWh provides an energy buffer where grid capacity is limited. Connector options: CCS1 or CCS2 can be configured for the target fleet. Mobile deployment: The trailer can move between work zones and project phases. Site suitability: Designed for temporary sites and dispersed equipment locations. Impact: Reduce travel to distant chargers, keep equipment closer to the work area and support phased electrification without installing a permanent charger at every location.
