Dead batteries, idle-fuel waste, and costly towing fees are chronic money pits for long-haul trucking. What if a single power system could eliminate all three—and pay for itself?
What Is the CARKU Truck Power System?
CARKU introduces a “1+N” Full-Scenario Energy Ecosystem that transforms trucks from fuel-consuming vehicles into clean, autonomous power hubs:
- The “1”: CBL230D-24V—a dual-purpose LiFePO4 battery providing relentless engine-cranking power alongside long-lasting cabin energy.
- The “N”: An integrated suite of parking Air Conditioner, power inverters, solar panels, and more.
Volume-tested and market-ready, CARKU turns driver rest hours into pure cost savings.
Why Does the CARKU Truck Power System Matter?
The system delivers impact across the triple bottom line: planet, people, and profit.
Environmental: Eliminates overnight engine idling, dropping CO2 emissions by ~90 kg per 10-hour rest. An 8–10 year LiFePO4 lifespan also keeps dozens of toxic lead-acid units out of landfills.
Social: A silent, engine-off cab delivers restorative sleep for drivers, while reliable morning starts prevent costly delivery delays.
Economic: Ending idle fuel burn, roadside rescue calls, and frequent battery replacements delivers a rapid, predictable ROI.
How CARKU Tested the CBL230D-24V
Want a quick overview first? [Click here to watch the operation video.]
Step 1: Read the product manual.
Before touching the truck, confirm the vehicle’s system voltage and the installation requirements in the manual.
Step 2: Connect it correctly.
Follow the manual for wiring, paying close attention to polarity and cable gauge. The CBL230D-24V is designed to replace the original lead-acid battery directly, so the truck’s existing wiring stays untouched.
Step 3: Download and pair the CARKU Battery App.
Once connected, open the app to check the battery’s charge level, voltage, and live status before running any tests.
Step 4: Test the starting function.
Start the engine and note how the battery performs, especially on a cold start.
Step 5: Test parking power.
With the engine off, run real loads such as a parking AC and a refrigerator. Record how long the battery sustains them and how the app reports the remaining charge.
Does it Work? Test Results
To verify whether the dual-purpose lithium battery delivers on its promises, we tested it across two core functions:
Function 1: Reliable Low-Temp Engine Starting
Starting a massive commercial diesel engine in sub-zero environments is the ultimate test for any heavy-duty battery. In extreme cold-weather field trials conducted in Russia, the 24V lithium battery demonstrated exceptional cold-cranking performance, successfully firing up heavy-duty diesel engines in sub-zero temperatures.

Function 2: Zero-Idle Cabin & AC Powering
Overnight climate control is usually a fleet’s biggest hidden expense. Running a parking AC by idling the diesel engine consumes roughly 34 liters of diesel over a standard 10-hour rest period. By switching to CARKU’s engine-off architecture, idle fuel consumption drops to zero.
These massive fuel savings are driven by the synergized combination of CARKU’s dual-purpose lithium battery and its high-efficiency Power Inverter:
- The Lithium Foundation:Stores abundant, long-lasting energy capable of sustaining deep discharge cycles.
- The High-Efficiency Inverter: Converts 24V DC to steady AC power with ultra-low conversion loss—ensuring maximum energy reaches your parking AC, refrigerator, and household appliances.
With the battery storing the energy, the next question is how to turn it into usable AC power, and what size inverter your air conditioner needs.
What Size Power Inverter for a Parking Air Conditioner?
The right inverter depends on your air conditioner’s running watts plus its startup surge, with 20–25% headroom. The CARKU CI2200C-24 (2200W rated) suits parking air conditioners that run up to roughly 1,800W.
Meet the CARKU power inverter CI2200C-24, built to pair with the dual-purpose lithium battery on a 24V truck system:
- 2200W rated power: Enough to run a parking air conditioner or refrigerator with the engine off, provided the load stays within rated limits.
- 24V DC input, 220V / 50Hz AC output: Matched to 24V trucks and for 220V markets.
- Bidirectional operation: Supplies AC power from the battery, and when plugged into mains power, it charges the lithium battery.
- USB ports: Includes standard USB-A and USB-C output ports (5V/3A each) for phones and other onboard electronics.
- Compact and light: 280 × 200 × 92 mm and just 2.9 kg.
