Volvo’s mini excavator and electric technology is leading the remarkable transformation in construction equipment.
Volvo’s ECR18 and ECR25 Electric models are proving that electric excavators match their diesel counterparts’ digging power while helping the environment.
These machines work actively for up to four hours per charge and excel in urban construction projects.
The ECR25 Electric weighs between 2680 to 2780 kg and dominates the electric construction equipment market. Tests show these machines work efficiently even in tough conditions.
The ECR18 Electric uses just 5.6 kWh of energy to dig a 20 metre trench. These excavators also let crews work in noise-sensitive areas without expensive fume extraction systems. Their charging speed impresses too – they reach 80 per cent capacity in just one hour, which keeps downtime low.
Rise of Volvo’s Electric Excavator range
Electric mini excavators mark a fundamental change in construction equipment design. Volvo Construction Equipment leads this change with groundbreaking engineering and eco-friendly solutions.
Volvo started its journey in electric machinery by launching its first electric compact excavators. The product line now has multiple models that serve different applications.
The ECR25 Electric, with its 20 kWh battery capacity, laid the foundations for future developments. The ECR18 Electric and EC18 Electric models expanded the lineup to give operators more choices based on their specific needs.
The electric drive system has several vital components that work together. These machines use lithium-ion batteries and dedicated electric motors instead of conventional diesel engines. The system powers the hydraulics through:
- An electric motor for hydraulic movement control
- Advanced hydraulic systems for precise operation
- Integrated power management controls
Battery technology and power management
Power management systems are a significant advancement in electric excavator technology. The machines feature sophisticated battery configurations:
The ECR25 (20kWh) has a battery capacity runtime of up to six hours, the ECR18 (16kWh) up to five hours, and the EC18 (20kWh) between three to five hours.
These machines provide flexible charging options. The built-in charger delivers 3kW power output and completes a full charge in about six hours. Projects that need faster turnaround can use optional fast off-board chargers to reach 80 per cent charge in just one hour.
The battery systems last as long as the machine’s operational life and deliver up to 2000 full charge cycles. This technology advancement will give consistent performance throughout the equipment’s service life, particularly in demanding construction environments.
ECR18 vs ECR25
The main difference between Volvo’s ECR18 and ECR25 mini excavators shows up in their specifications and capabilities. Each machine is built to tackle specific construction challenges.
The ECR18 Electric weighs between 1790-1870 kg, making it lighter than the ECR25 Electric at 2680-2780 kg.
Both models shine in urban environments with distinct performance features. The ECR25 Electric comes with an 18 kW electric motor that makes it ideal for tougher urban jobs.
Application-specific capabilities
These machines adapt well to construction projects of all sizes. The ECR18 Electric delivers:
- Up to five hours of operational time per charge
- Ultra-short tail radius for confined spaces
- Integrated 3kW on-board charger
The ECR25 Electric stands out in:
- Indoor demolition work
- Underground utility operations
- High-dust environment applications
Both models use maintenance-free lithium-ion batteries. The ECR18’s battery capacity is 16 kWh, while the ECR25 provides 20 kWh.
Quick charging keeps productivity high, and the ECR25 reaches 80 per cent charge in about 50 minutes with a 400 VAC 32A supply.
Urban construction applications
Volvo mini excavators have created new possibilities for urban construction projects that were once hard to complete. These electric machines show their value in demanding applications of all types by combining power with environmental consciousness.
- Indoor demolition and renovation
Electric excavators have changed how indoor demolition work gets done. These machines work without getting pricey fume extraction systems.
Workers breathe cleaner air and feel less tired after their shifts. These machines pack the same power as diesel ones, so there’s no drop in performance during tough demolition jobs.
- Underground utility work
The compact design of these electric excavators makes underground utility work substantially better. Their reduced tail swing barely extends past the track width, which makes them perfect for tight underground spaces.
Manufacturers have added these features to make them more durable:
- Width-protected swing frames for improved stability
- Steel track undercarriage options for demanding conditions
- Quick-coupler-ready designs for efficient attachment changes
- Noise-restricted zone operations
Electric excavators have made work in noise-sensitive areas much easier. The ECR25 Electric lets construction teams work at night in populated areas. This helps reduce traffic congestion during busy hours. The machines run so quietly that workers can communicate better and guide operators while staying at safe distances.
Performance testing methodology
Volvo’s electric mini excavators went through 6-month old rigorous testing protocols to review their performance in different operating conditions. The testing methods give a complete picture of these machines’ capabilities in real-life scenarios.
The testing framework targets three main operational scenarios: standard utility work, heavy demolition, and indoor operations.
Each machine goes through performance tests in different working conditions. Runtime measurements range from 4 to 6 hours per charge. The testing protocol has:
- Environmental temperature monitoring
- Operational load variations
- Battery performance under stress
- Charging cycle efficiency
Both ECR18 and ECR25 models follow standardised measurement criteria. A well-laid-out framework tracks key performance indicators. The main hydraulic pump flow rate stands at 58l/min.
Advanced monitoring systems track performance metrics through multiple operational cycles. The testing equipment undergoes regular calibration to maintain accuracy. The analysis framework reviews:
- Battery performance metrics:
- Charging efficiency from 0-80 per cent in 50 minutes
- Power consumption patterns
- Temperature variation effects
- Operational efficiency:
- Work cycle completion times
- Energy consumption per task
- System response rates
The testing methods follow complete safety protocols. All equipment goes through regular inspection and testing. This approach ensures reliable data collection and maintains operational safety standards. The analysis looks at both normal and quick charging scenarios. Charging times receive careful monitoring under various power supply setups.
Volvo’s electric mini excavators have showed impressive capabilities in ground applications during field testing. The results give solid proof that these machines work well in construction operations.
> Digging power and efficiency
The ECR18 Electric proves its worth in tough conditions. It dug a 20-metre trench while using just 5.6 kWh of energy. The ECR25 Electric matches diesel machines with a breakout force of 22.3 kN. This shows the move to electric power keeps performance strong.
Performance metrics show these key capabilities:
- The ECR25 Electric digs up to 2965 mm deep
- Operating weight ranges from 2680 to 2780 kg
- Sound levels stay at 74 dB at the operator’s position
> Runtime and charging cycles
Field tests confirm these machines’ operational endurance really well. The ECR18 Electric works up to five hours per charge. The ECR25 Electric runs up to four hours on a single charge.
Electric excavators’ economic benefits are clear. Operators save money on energy costs and need less maintenance.
- Energy cost savings:
Maintenance costs drop by up to 50 per cent compared to diesel options. The lithium-ion batteries last up to 2000 full charge cycles, matching the equipment’s life expectancy.
These machines offer more than just cost savings. Electric mini excavators work better in many jobs. They let crews work in noise-sensitive areas and indoor spaces without expensive ventilation systems. This flexibility and proven performance make them great options for modern construction work.
