Kalmar has introduced its new generation of lithium-ion battery packs, now available globally, for its electric straddle carrier product line. The newly released Gen 2 battery features an upgrade in nominal capacity to 533 kWh—an increase of 25 percent over Kalmar’s previous battery generation. Usable capacity for the new battery is rated at 453 kWh.

Kalmar says that the Gen 2 battery solution is designed to support demand for improved energy capacity, safety and operational efficiency in cargo handling equipment. The updated cell chemistry extends battery lifespan, which Kalmar claims will reduce replacement frequency and lower total cost of ownership. Enhanced thermal stability is also noted as part of the safety improvements.

According to Kalmar, the Gen 2 battery enables net operating times of up to 10 hours for electric straddle carriers, depending on energy consumption levels. This operating profile supports various charging strategies, including a combination of depot charging during breaks and hands-free opportunity charging during active shifts. The system allows for hot-seat operation, where equipment remains in continuous use by alternating operators.

Kalmar has also deployed a megawatt charging system at its test facility in Tampere, Finland to support development and validation of the Gen 2 battery integration.

“Gen 2 represents a major step forward in terms of battery energy capacity, safety and operational lifespan,” said Marko Hopeaharju, Head of Horizontal Transportation Solutions at Kalmar. “With longer operating times and improved reliability, our customers can transition to fully electric fleets without compromising performance.”
