Kalmar has launched a second-generation lithium-ion (Li-ion) battery solution for its electric straddle carriers, marking a significant upgrade in energy performance, safety and operational efficiency
The new Gen 2 battery is designed to deliver higher energy capacity, improved thermal stability and longer operating hours, and is now available to customers worldwide.
Developed in response to increasing demand for safer, more efficient and sustainable cargo-handling equipment, the Gen 2 battery incorporates advanced cell chemistry that extends battery lifespan and reduces replacement frequency. This results in a lower total cost of ownership for customers, while also improving lifecycle sustainability compared with previous-generation technology.
The new battery offers a nominal capacity of 533 kWh, representing a 25% increase over its predecessor, with a usable capacity of 453 kWh. This enhanced capacity enables longer operating cycles and greater flexibility in charging strategies. Operators can combine scheduled depot charging during breaks with hands-free opportunity charging during operations, supporting hot-seat usage and continuous workflows. Depending on energy consumption, electric straddle carriers equipped with the Gen 2 battery can achieve up to 10 hours of net operating time.
Alongside the battery launch, Kalmar has also commissioned a megawatt charging system (MCS) at its test facility in Tampere, Finland, supporting faster and more efficient charging for high-capacity electric equipment.
“Gen 2 represents a major step forward in terms of battery energy capacity, safety and operational lifespan. With longer operating times and improved reliability, our customers can transition to fully electric fleets without compromising performance.”
The introduction of the Gen 2 battery reinforces Kalmar’s commitment to advancing electrification and decarbonisation in port and terminal operations, supporting customers as they move toward fully electric cargo-handling fleets.
