For decades, the refrigerated transport industry has relied on a standard piece of equipment: the standalone diesel generator (genset) mounted to the truck or trailer. It’s a simple, albeit noisy and inefficient, solution to a complex problem. But what if that “simple” solution is quietly costing your business a fortune?
The numbers don’t lie. The constant drone of that small diesel engine is the sound of money being burned—in fuel, in maintenance, and in eventual replacement. We’ve done the math, and the results are staggering.
It’s time for a smarter, more efficient, and vastly more profitable solution.
The Problem: The Hidden Cost of Your Refrigeration Genset
Let’s break down the typical costs of running a standard 15kW diesel genset for a refrigerated truck.
Based on industry-average data, a genset operating 10 hours a day for 250 days a year will consume around 6,600 liters of diesel. At today’s prices (e.g., $1.90/L), that’s $12,540 annually in fuel alone.
But the costs don’t stop there. These engines require constant service. Factoring in oil changes, filters, and labor, you can add another $2,000 per year in maintenance costs.
Total Annual Cost (Traditional Genset): $14,540
This is a significant operating expense for a single truck. For a fleet of ten, it’s nearly $150,000 every year, simply disappearing into fuel exhaust and engine parts.
The Solution: The Safiery Hybrid Electric System
At Safiery, we knew there had to be a better way. We’ve developed a fully integrated Hybrid Electric System that replaces the wasteful genset, leverages the power of your truck’s main engine, and slashes operating costs.
Our system is built on four key components working in perfect harmony:
-
- A High-Efficiency 400V DC Refrigeration Unit: We start with a 30%+ more efficient 400V DC Mitsubishi refrigeration system. This DC-native unit eliminates the energy-wasting conversion from AC power that plagues traditional systems.
- A 10kW Belt Motor Generator (BMG): This is the powerhouse of the system. The BMG replaces the truck’s standard alternator and generates a massive 10,000W of power, running directly from the main truck engine.
- 48V Solid State LFP Lithium Batteries: This rugged, 10,000-cycle battery bank acts as the system’s energy buffer. It stores the power generated by the BMG and delivers it smoothly to the refrigeration unit, ensuring the cold chain is never broken—even when the truck is off.
- “Scotty AI” System Brain: The Scotty AI controller is the “brains behind it all”. It intelligently manages the flow of power, drives the BMG at its peak efficiency, and communicates with the lithium battery’s BMS to optimize charging and protect the system.
How It Works: The “Secret Sauce” of Efficiency
Here is where the real magic happens. Our system doesn’t just generate power; it makes your entire truck more fuel-efficient.A truck’s engine has an optimal efficiency range (its Brake Specific Fuel Consumption, or BSFC). When cruising, the engine is often operating below this optimal point, wasting potential energy.
Our Scotty AI and BMG system detects this. It strategically “loads” the engine by using its excess torque to generate electrical energy and charge the 48V batteries. This small, additional load pushes the main engine into a far more efficient BSFC range. In one example, we see the engine efficiency improve from a poor 455 g/kWh to an excellent 320 g/kWh.
You are literally getting more from every drop of diesel you’re already burning to move the truck. Instead of running a second diesel engine (the genset) at a terrible efficiency (280 g/kWh) , you’re using your primary engine at its peak efficiency (a system BSFC of just 67 g/kWh).
The Proof: The Numbers Don’t Lie
So, what does this revolutionary efficiency mean for your bottom line?
Let’s look at the costs for the exact same truck fitted with the Safiery Hybrid Electric System.
The system’s high efficiency means it consumes a fraction of the fuel. Our calculations show an annual fuel consumption of just 700 liters. At the same $1.90/L, that’s only $1,330 per year in fuel.
And maintenance? The BMG is a brushless, IP67-rated, low-maintenance component. The solid-state batteries are rated for 10,000 cycles. We estimate the annual maintenance cost at a minimal $500.
Total Annual Cost (Safiery Hybrid System): $1,830
Annual Savings Per Truck: $12,710
Built for the Real World
This isn’t just a concept. It’s a robust, road-ready solution. The Safiery BMG is purpose-built for this task, offering 85% efficiency (hot), dual redundancy for safety, and AI auto-tuning.We’ve even engineered an intelligent recovery system. In the unlikely event the 48V battery bank is fully drained, the system uses the truck’s standard factory alternator to charge a small 24V recovery battery, which then safely wakes up the Scotty AI, starts the BMG, and brings the entire system back online—all just by starting the truck.

Stop Burning Money. Start Saving.
For every truck in your fleet still running a diesel genset, you are missing out on over $12,700 in pure profit every year.The Safiery Hybrid Electric System is more than just an upgrade. It’s a fundamental shift in how refrigerated transport is powered. It’s quieter, cleaner, far more reliable, and dramatically more profitable.
Stop feeding the genset. It’s time to invest in efficiency.
