PowerAccESS DC
PowerAccESS is Cavotec´s modular solution for powering and hybridising port cranes. Built using the latest technologies
and backed by years of engineering expertise, it delivers
reliable zero-emission power in demanding and evolving port
environments.
Its modular design enables crane manufacturers to configure
the system to their specific requirements while benefiting from a standardised, future-ready platform.
Applications
PowerAccESS is Cavotec’s modular and mobile Energy Storage System (ESS) designed to provide reliable zero-emission power for port cranes during block changes as one-to-one replacement for diesel generators. PowerAccESS can also be configured for hybrid power or full battery operation, with the ability to capture regenerated energy from the crane. Engineered for challenging and variable operating conditions, PowerAccESS ensures efficient power delivery at every port.
Our modular design allows crane manufacturers to tailor the system to their specific needs while maintaining a standardized platform – reducing costs,simplifying upgrades, and eliminating the need for expensive bespoke
Technical characteristics
PowerAccESS combines proven expertise within a single integrated design to meet the unique demands of port operations worldwide.
Modular Design
- Configurable with two enclosure sizes:
62 kWh or 124 kWh storage
124 kWh to 494 kWh storage - Configurable with multiple battery pack
sizes for the DC variant: 248 kWh,
310 kWh, 372 kWh, 434kWh or 496kWh
Sustainable Design
- Lithium Iron Phosphate (LiFePO4)
batteries for enhanced safety, stability,
and extended service life - Cells that are bolted rather than
welded, making them easier to disas
semble and recycle at the end of life,
supporting a circular economy
