Echandia has been selected to deliver a new battery system for an all-electric ferry in Denmark, supplying a 3.2 MWh LTO battery system to replace the previous 4.3 MWh NMC system. The new system is designed for a 15-year lifetime and features multiple daily fast-charging cycles at high efficiency.
Echandia’s LTO (lithium-titanate oxide) technology is well-suited for high-frequency, fast-charging RoPax ferry operations, where reliability is critical. The system supports very high C-rates, enabling over 20,000 charge cycles and charging in around 25 minutes. It is an improvement of 10 minutes per charging session.
Delivered in 2019, the Danish ferry was the world’s first long-range, pure electric ferry and a symbol of zero-emission passenger transport. Now eight years old, the original battery system will be replaced due to uneven wear and reduced capacity. Scheduled operation with the new battery system will be in May 2026.
The replacement proves that upgrading earlier-generation batteries with modern systems is both technically and financially viable, offering longer lifetime, higher efficiency, and the highest standards of safety.
