A: This is precisely where Nengyixing’s "Nengyu" series of mobile energy replenishment systems shines—offering plug-and-play capability without the need for fixed infrastructure:
【Need to charge heavy-duty vehicles / Rapid capacity expansion at fixed sites】
Recommended: "Mobile Charging & Storage Truck." Features a 1.935 MWh containerized energy storage system, six 160 kW charging guns, and a total output of 960 kW. It serves as a stationary storage unit to capture peak-valley price arbitrage during normal times and can be deployed to sites for capacity expansion and energy replenishment during peak periods.
【Need for temporary power supply at construction sites, events, or for emergencies】
Recommended: "Mobile Power Supply Truck." Equipped with standardized heavy-duty truck battery-swapping packs and a PCS (Power Conversion System) inverter, it delivers a stable 250–520 kW/400V AC power output. Key advantage: Batteries can be swapped for fully charged ones at any heavy-duty truck battery-swapping station—eliminating charging downtime and enabling continuous power supply.
【Need for roadside assistance / Emergency vehicle charging】
Recommended: "Mobile Charging Truck." Available in lightweight (40–80 kW; adds 50 km of range in 10 minutes) and heavy-duty (160–320 kW) versions, catering to emergency scenarios for passenger vehicles and commercial vehicles, respectively.
【Need to set up battery-swapping points at temporary sites, ports, or mines】
Recommended: "Mobile Battery-Swapping Truck." A 6x4 heavy-duty semi-tractor equipped with an intelligent battery-swapping robot and six battery slots; compatible with various battery specifications, it enables immediate swapping upon arrival—ideal for temporary operational sites lacking fixed battery-swapping stations.

A: The two serve different purposes; the right choice depends on your core requirements:
  Mobile Charging & Storage Vehicle = Integrated energy storage and charging. It features a high power output of 960kW, capable of charging multiple vehicles simultaneously. It is ideal for scenarios requiring fixed deployment at a specific site to serve multiple vehicles, such as capacity expansion at highway service areas or support for large-scale events.
  Mobile Charging Vehicle = Battery + DC-DC converter. With a total weight of only 18 tons and a power output of 40–320kW, it offers greater mobility and flexibility. It is suitable for scenarios requiring frequent movement, such as roadside assistance for new energy vehicles, emergency top-ups, and rapid charging for individual vehicles.
If you are unsure which option best suits your needs, please contact our pre-sales support team; we will recommend a solution based on your specific application scenario.

A: The mobile power supply vehicle delivers a stable 380V AC output ranging from 100kW to 500kW. Typical application scenarios include:
  Green construction sites—replacing diesel generators to power construction equipment and lighting
  Film and TV production bases—providing silent power for filming equipment and lighting
  Emergency rescue—ensuring temporary power supply following natural disasters
  Large-scale events—providing temporary power for outdoor music festivals, sporting events, and more
Unique advantage: It utilizes standardized battery packs designed for heavy-duty electric trucks, allowing for direct, full-charge swaps at any compatible heavy-duty truck battery-swapping station. In other words, provided there is a compatible station nearby, you can simply swap in a fresh battery when the power runs low—eliminating the need to wait hours for a recharge and ensuring uninterrupted power supply.
