Kalmar has introduced a next-generation lithium-ion (Li-ion) battery solution for its electric straddle carrier, enhancing energy capacity, thermal stability and operating time. The new Gen 2 battery is now available to customers worldwide.
Developed to meet increasing demand for safer, more efficient and more sustainable cargo-handling solutions, the Gen 2 battery features advanced cell chemistry that extends battery lifespan. This results in a lower total cost of ownership by reducing replacement needs, while also improving lifecycle sustainability.
The new battery offers a nominal capacity of 533 kWh, representing a 25% increase compared with the previous generation, and a usable capacity of 453 kWh. This additional capacity enables longer operating times and greater flexibility in charging strategies. Operators can combine depot charging during breaks with hands-free opportunity charging during shifts, supporting hot-seat operation.
Kalmar electric straddle carriers equipped with the Gen 2 battery can achieve a net operating time of up to 10 hours, depending on energy consumption and operating conditions.
In parallel with the battery launch, Kalmar has deployed a megawatt charging system (MCS) at its test facility in Tampere, Finland, supporting the development and validation of high-capacity electric solutions.
“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.”
