Rosenbauer International : Presents the RS 14 for Roadside Assistance

• Power generator for fast charging of broken down electric vehicles
• Continuously loadable power pack with a constant output power of 10.88 kW
• RS 14 SUPER SILENT with special enclosure for lowest noise emissions

Rosenbauer is launching a modern and simple solution for getting stranded electric vehicles back on the road quickly and reliably. It consists of a power generator from the RS 14 series and a matching quick charger, which enables mobile charging with an output power of 10.88 kW. This is equivalent to the power of modern wallboxes. After a short power boost, the batteries of the electric vehicle are recharged to the point where the journey can be continued. The simple formula for this is: 15 minutes of charging with a power generator from the RS 14 series will get an electric car at least 10 kilometers.

Without a charging assistant, electric vehicles must be transported away on the loading platform of a roadside assistance vehicle. They should not be towed, as this can damage the control electronics if the on-board system is not activated. As a rule, they are transported to the nearest charging station, where the batteries can be recharged. Or at least so far that the stranded vehicle no longer poses a danger or hindrance to other road users (removal from blind bends and tunnels, from bridges or highway sections without a service lane). A quick charging assistant directly at the breakdown location with the RS 14 (or RS 14 SUPER SILENT) and quickstarter combination, however, is faster, less complicated, and involves much less effort.

Technology for emergencies

The great advantage of this solution is that it is 100% suitable for emergencies. The Rosenbauer power generator never runs out of power. As a fire-fighting device, it is capable of withstanding continuous loads and provides constant energy for hours, which can be used, for example, as an emergency power supply in the event of a disaster and for charging several batteries in succession during roadside assistance. The power pack consists of a synchronous generator, driven by a 2-cylinder four-stroke gasoline engine, which can be supplied with fuel without interruption via an external refueling set. The power generator is also very robustly built because it has to withstand high loads and great heat in tough fire fighting operations. In addition, the RS 14 is the lightest and most compact unit in its power class (14 kVA). It can be mounted in a space-saving manner in emergency or roadside assistance vehicles, or permanently installed, transported on trailers with a custom-fit weather protection tarp and equipped with a wheel set to ensure easier handling and quick manual transport to the site of operation.

The quick charger, on the other hand, charges all current electric vehicles. It has a standardised type 2 plug on the vehicle side and a 400V/16A CEE plug on the other side for fast transmission of three-phase alternating current at 400 V, resulting in 11 kW of power for charging an electric car using all three phases. In addition, residual current monitoring is integrated to guarantee safe charging of a wide range of electric vehicles.

Elegant retrofit solution

Every fire department has vehicles in use that have a power generator on board. If this is sufficiently powerful, such as the Rosenbauer RS 14 or the RS 14 SUPER SILENT, only the quick charger is required, and you have a mobile emergency charger for broken-down electric vehicles. For towing companies and motorist clubs, the combination of power generator and quick charger is a highly recommended retrofit solution.

The quick-charging service will certainly be necessary in the future, as is clearly evident in the US. There, it is already possible to call so-called mobile chargers, which will recharge the battery for the journey to the next charging station if the electric vehicle has come to a standstill.
