ROYPOW, a global leader in motive power and energy storage solutions, has recently expanded its business to power specialty vehicles with innovative all-electric Auxiliary Power Unit (APU) solutions.

Specialty vehicles are designed and manufactured for efficient operation in complex or extreme conditions while reducing costs associated with idling. As urbanization accelerates and technology advances, demand for these vehicles is growing across industries like emergency rescue, environmental protection, cold chain supply, and engineering, driving the demand for effective APU solutions to meet rising power requirements on vehicles. ROYPOW provides ideal choices.

ROYPOW all-electric APU solutions include:

Automotive-grade LiFePO4 batteries support an expandable capacity of up to 40kWh, ensuring all-day cool comfort even in the scorching summer, providing both safety and comfort.
The 48V all-in-one inverter integrates the MPPT controller, charger, and inverter into one efficient unit and supports parallel working, enabling greater power for vehicle loads and efficient charging.
The DC-DC converter efficiently boosts the vehicle’s original 12V to 48V for optimal battery charging.
The 48V inverter air conditioning system supports efficient cooling and heating.
The Energy Management System (EMS) provides real-time monitoring and control.
Solar panels can enhance self-sufficiency and sustainability.

Here is a typical customer case from Texas:

After installing the ROYPOW APU system, the client powers the DC 48V air conditioner directly with lithium batteries, eliminating the need for the engine idling to drive a mechanical air conditioner. This saves approximately $1,000 to $1,500 in diesel costs each month. Additionally, by replacing the original lead-acid batteries with lithium batteries for powering electrical devices in the cabin equipment, the client no longer needs to replace lead-acid batteries every six months, saving about $1,000 every six months. Overall, the return on investment for using the ROYPOW lithium battery APU system is achieved within 6 to 8 months
