Global power company Cummins is looking for ways to reduce RVers’ reliance on gasoline while enjoying all the off-grid power they need to use their camping gear and accessories for camping. Its new hybrid concept seamlessly combines battery storage and gas-powered power generation to provide power for days while reducing noise and emissions.
Just as RV manufacturers themselves have been doing for years, Cummins designed their electrical systems to store enough energy to run a variety of onboard camper equipment on or off the grid. Start with a large Lithium-Ion Leisure battery. However, Cummins added a 2.8 kW Onan QG 2800i petrol generator to keep the battery from going to zero, instead of relying solely on solar panels and a vehicle alternator charge to maintain his 6.7 kWh battery. increase.
According to Cummins, the combination provides the same amount of overall power as a 5 kW generator, but with less noise, emissions and vibration. Although the battery runs quietly, the QG 2800i is designed for efficient operation with less noise and vibration than larger generators. Comparing the spec sheets, the 2800i has a noise level of 65 dB(A) compared to 69 dB(A) for the 5.5 kW Onan QG 5500 RV generator.

The third component of the Cummins concept is a power distribution hub that manages the outputs and inputs from dual power supplies. It houses the inverter, converter and charger hardware in a compact box. The system is also solar powered and supports up to 500 watts of solar input.
Cummins has not mentioned any specific plans to bring the hybrid system to market, framing it as part of a larger study of RV power solutions aimed at propelling the market towards a net-zero future. I’m here. The concept says it complies with the 2024 California Air Resources Board (CARB) Small Off Road Engine (SORE) requirements.
The latest CARB SORE measures, approved in late 2021, allow small “off-road” engines, such as those used in leaf blowers and lawn mowers in new MY2024+ equipment sold in California, to produce zero emissions. is asked. Restrictions on portable generators, including those used in RVs, don’t have to be completely zero-emissions by 2024, but they do have to meet stricter emissions requirements than before. must meet zero emissions standards by 2028.

Cummins debuted a new hybrid power concept at the 2023 Florida RV SuperShow, which concluded on Sunday. Cleaner RV power proved to be a central theme of the show. Also, Winnebago showcased his prototype of the latest all-electric camper.
