The transition to electrically powered mobile machinery is in full swing. Lithium batteries, in combination with electric drives, play a crucial role in this shift. They offer a quieter, more sustainable, and more user-friendly alternative to traditional lead-acid batteries and combustion engines. But how does this work exactly? And what advantages do these batteries bring?
How lithium batteries power ePTO Systems
A good example of lithium battery applications in mobile machinery is the electric Power Take-Off (ePTO) system. This system enables vehicle tools, such as cranes, to be powered by an electric motor.
A practical example is a truck with a hydraulic crane mounted behind the cab. Normally, the diesel engine keeps running to power the crane. This is inefficient and causes unnecessary emissions and noise. With an ePTO and a lithium battery, the crane can operate electrically, which is not only quieter but also saves fuel and reduces CO₂ emissions. The same battery pack can also be used for other electric tools, such as drills or pressure washers.
Other applications—such as pressure washers for urban cleaning, mowing boats, and garbage trucks—also benefit from battery-electric drives. Vehicles that return to a fixed charging location daily are especially suitable for electrification. But how do lithium batteries perform compared to lead-acid batteries?
Advantages over lead-acid batteries
Many companies still use traditional lead-acid batteries, but switching to lithium offers substantial advantages:
- Longer lifespan: Lead-acid batteries typically last 300 to 600 charge cycles, while lithium batteries can reach up to 2,000 cycles before their capacity drops below 80%.
- Lower maintenance: Lead-acid batteries require regular maintenance, such as refilling with demineralized water and checking acid levels. Lithium batteries are low-maintenance.
- Better performance: Lithium batteries have a higher energy density and deliver consistent power, whereas lead-acid batteries experience more performance and capacity loss with frequent discharges.
- Total Cost of Ownership (TCO): Although lithium battery systems have a higher upfront cost than comparable diesel drives, the longer lifespan, lower maintenance, and improved efficiency make them more economical in the long run.
While the practical and economic benefits are clear, safety is also an important consideration. So how safe and sustainable are lithium batteries in practice?
Lithium batteries: safe and sustainable
A common misconception about lithium batteries is that they pose a fire risk. In practice, however, batteries that are properly designed and applied are very safe. ePTO systems often use LFP (Lithium Iron Phosphate) batteries, which are known for their stability and minimal risk of thermal runaway (overheating and spontaneous combustion).
Electrification also contributes to more sustainable workplaces. Lithium batteries produce no direct emissions and reduce noise levels on site, resulting in a healthier work environment. With these safety and sustainability benefits, it’s clear that lithium batteries play a key role in the future of mobile machinery. But what does that future look like?
The future of mobile machinery: fully electric?
Stricter emission regulations and the demand for sustainable solutions are accelerating the electrification of mobile equipment. Sectors like agriculture and construction are seeing growth in hybrid and fully electric machines. For companies considering the switch, it’s important to carefully assess energy requirements and charging options.
Lithium batteries are a reliable and sustainable power source—provided they are properly maintained. With just a few simple steps, you can prevent unnecessary wear and tear.
Prevent wear and malfunctions with proper maintenance
To get the most out of your lithium battery, proper maintenance is essential. While lithium batteries require significantly less maintenance than lead-acid batteries, there are a few key best practices to help prevent wear and malfunctions.
One of the most common mistakes is storing batteries fully charged or completely discharged for long periods. Roel, battery specialist at Variodrive, advises:
“If you store a battery for an extended period without using it, it’s best to keep it at 40–50% charge and only recharge it before use. This prevents unnecessary degradation and extends battery life.”
It’s also important to perform a full charge cycle regularly—once a week to 100%, for example—to keep the battery electronics functioning optimally. Keeping the battery terminals clean is also crucial. Dust and dirt can affect performance, so regular inspection and cleaning are necessary.
By following these simple maintenance guidelines, your battery stays in top condition and the risk of malfunction is minimized. But beyond maintenance, choosing the right battery is just as important. So why choose lithium batteries from Variodrive?
