Lumikko BTMS
Battery Thermal Management System for Railway Applications

Lumikko BTMS – Custom battery thermal management for demanding railway environments

As railway applications become more electrified, battery systems require reliable and precisely controlled thermal management. Lumikko BTMS (Battery Thermal Management System) is a modular liquid cooling system that can be tailored to the technical and operational requirements of railway vehicles, onboard energy systems and project-specific electrified rail applications. Designed for demanding conditions, Lumikko BTMS helps manage battery temperatures efficiently, supports long component lifetime and enables system integration within the constraints of railway vehicle architecture.

Built on over 50 years of expertise, Lumikko designs solutions that perform reliably in the toughest conditions – whether facing heavy vibration, marine environments, or extreme temperature shifts.

A well-designed Battery Thermal Management System helps maintain battery operation within the desired temperature range, supports predictable performance and reduces unnecessary stress on battery components. Battery temperature affects performance, charging behavior, operating lifetime and system availability. In railway applications, thermal management must perform consistently across changing ambient temperatures, fluctuating loads and long operating cycles. 

Battery thermal management designed around your railway application

Every railway project is unique. Existing vehicle structures, limited installation space, interfaces, safety requirements, maintenance access and operating conditions all influence the final solution. That is why Lumikko BTMS is not a one-size-fits-all unit. It is a customizable thermal management solution that can be configured and adapted to meet the needs of specific railway applications. Whether the project involves a new electrified rail vehicle, an onboard battery system or a retrofit application, Lumikko supports customers identifying the right technical concept for reliable battery temperature control.

Adaptive heating with the use of braking energy -Tampere Tramway

Lumikko’s regenerative braking system is an innovative and environmentally friendly solution that utilises the energy generated by tram braking and stores it in an innovative brake resistor system integrated into the HVAC device. The system converts kinetic energy into electrical energy that can be used to heat the cabin or stored for later use. In this way, the system reduces the energy consumption and emissions of trams and improves passenger comfort.
