BTMS (Battery Thermal Management System)
Temperature is one of the most critical factors affecting the performance, safety, and lifetime of batteries used in railway applications.
To ensure optimal operation, batteries must be maintained within their ideal temperature range, typically between 15°C and 35°C. Operating outside this range can significantly reduce battery efficiency, accelerate cell aging, and shorten overall service life.
TELEMA BTMS is specifically designed to keep batteries within their optimal operating conditions, maximizing performance, improving energy efficiency, and extending battery lifetime—even in the most demanding railway environments.
