When an electric vehicle runs low on a motorway hard shoulder, in a car park or at a remote site, the rescue team needs charging equipment that is quick to deploy, simple to connect and powerful enough to send the driver on their way. MPMC’s BCH Series offers plug-and-play mobile charging units that carry their own energy, connect to the vehicle through standard CCS2 guns and need no installation, making them a practical tool for roadside rescue and emergency charging providers.

Matching the Unit to the Rescue Task

Compact Units for Cars and Vans

The BCH-80-70 is a compact mobile charger measuring 1,460 x 780 x 1,200 mm and weighing 880 kg. It delivers 80 kW of DC charging from 70 kWh of storage through a liquid-cooled CCS2 gun rated at 260 A, with a 7 m cable that reaches vehicles parked awkwardly at the roadside, and an output range of 200 to 1,000 V for both 400 V and 800 V vehicles. It operates from -20°C to +55°C and at altitudes up to 4,000 m.

Trailer Units for Larger Vehicles and Busy Sites

For vans, light trucks or several vehicles at once, the BCH-275-200 delivers 150 kW through two 250 A CCS2 guns from 203.5 kWh of storage. It rides on a 3.5-tonne heavy-duty trailer and its plug-and-play fast output box eliminates on-site wiring, so the crew can arrive, connect and start charging in minutes.

Its 125 kW of AC output can also power lighting and equipment at an incident scene or a temporary rescue base.

Note: The table compares the two models best suited to roadside rescue; the BCH Series also includes the BCH-60-70, BCH-600-400, BCH-800-600 and BCH-500-1000.

Keeping the Service Running Between Call-Outs

Fast turnaround is essential for a rescue service. The BCH-275-200 can refill its battery from a public fast charger through its CCS2 DC input in about one hour, and the BCH-80-70 also recharges through a CCS2 DC input at up to 70 kW, so units can be topped up at a depot or on the road between assignments.

Every BCH charging model runs an EMS with 4G and OCPP 1.6, so dispatch teams can see each unit’s charge level and status remotely, and optional RFID payment supports charging services billed at the roadside. MPMC’s revenue model for the series reflects the premium value drivers place on immediate charging access when they need it most.

CCS2 is standard, and CCS1, GB/T and CHAdeMO can be specified for markets or customers that need them.

Dependable Hardware for Unpredictable Work

Rescue units travel constantly and work in all weather. Blade LFP batteries with a sandwich structure tested for fire, water immersion, collision and crushing, rated for 6,000 cycles at 90% depth of discharge and held within 6.7°C by precision thermal control, give consistent output on every call. The BCH-275-200 adds CE-certified aerosol fire protection and a sealed liquid-cooled pack.

Integrated SCADA and EMS allow full remote monitoring and command, so a control room can check battery health and plan maintenance across the whole rescue network.
