ZEN LFP RAIL is Forsee Power’s modular high-energy battery platform specifically engineered for railway applications. Available in 36 kWh and 55 kWh battery packs, the range combines LFP chemistry, proprietary battery management technology and liquid thermal management to deliver safe, reliable and cost-efficient onboard energy storage.
Designed as a compact, rail-certified building block, ZEN LFP RAIL enables flexible battery architectures for catenary-free and catenary-less operations, hybrid rail applications and energy recovery, with system configurations reaching the high-voltage requirements of modern rolling stock.
High-energy batteries engineered for rail
Rail electrification requires battery systems capable of combining high energy, long operating life, stringent safety requirements and easy vehicle integration.
ZEN LFP RAIL has been specifically developed to address these challenges. Its modular architecture allows railway manufacturers and system integrators to configure the battery system according to the energy, voltage and integration requirements of each vehicle.
Based on Lithium Iron Phosphate (LFP) chemistry, the platform combines competitive cost with long cycle life and robust safety characteristics, making it particularly suited to railway applications requiring large amounts of onboard energy over extended operating periods.
- modular & scalable
- safe & reliable
- long life time
- easy integration & maintenance
Two battery formats. One scalable rail platform.
ZEN 36 LFP RAIL
The 36 kWh ZEN LFP RAIL is a compact high-energy battery pack designed for flexible integration into railway vehicles.
Its modular architecture enables several packs to be connected in series, reaching up to 324 kWh with nine packs and a nominal system voltage of 1,395 V.
With up to 6,000 cycles, the solution is designed for railway applications where long operating life and optimized Total Cost of Ownership are essential.
ZEN 55 LFP RAIL
The 55 kWh ZEN LFP RAIL provides greater energy capacity per battery pack for applications requiring large onboard energy storage systems.
Six packs connected in series provide 330 kWh of embedded energy, with a nominal voltage of 1,392 V. Multiple battery branches can then be integrated according to the total energy requirements of the vehicle.
With an energy density of 227 Wh/L and specific energy of 145 Wh/kg, ZEN 55 LFP RAIL combines high onboard energy with a compact modular architecture.
Supporting multiple rail electrification strategies
ZEN LFP RAIL can support different railway architectures, from battery-electric to hybrid vehicles. The system enables onboard energy storage for catenary-free and catenary-less operation and can store recovered energy for subsequent use.
Its scalable architecture makes the platform suitable for a broad range of rolling stock, including trains, locomotives, trams and other railway vehicles.
Safety and rail certification at the core
ZEN LFP RAIL combines the thermal stability of LFP chemistry with liquid thermal management and Forsee Power’s proprietary BMS technology. Integrated balancing, SIL2 voltage and temperature monitoring, alarms and CAN communication contribute to safe and reliable operation.
The platform is certified according to key battery and railway standards, including
- IEC 62928
- IEC 62619
- IEC 62620
- IEC 61373
- IEC 60077
- UN 38.3
