Precision thermal management for your batteries

Battery Thermal Management System (BTMS)

Innovative battery electric (BEV) and fuel cell electric (FCEV) vehicles require accurate management of battery temperatures to achieve essential range, performance and service life.

Providing intelligent thermal regulation, our field-proven Battery Thermal Management System (BTMS) is the solution of choice for many leading global OEMs.



Vehicle BTMS

Careful thermal regulation of temperature-sensitive batteries is critical to maximising the mileage and service life of on- and off-highway BEV and FCEV vehicles. Our third-generation (GEN3) Vehicle BTMS range includes a variety of configurations to offer constant temperature control in any chassis and any environment.


Designed specifically to meet the stringent compliance, homologation and validation requirements of the rail sector, our range of Rail BTMS solutions offers a fully compliant, easy-to-install and efficient ‘plug and play’ system that guarantees optimal battery thermal management for passenger and freight trains.

What is the GTS BTMS?

To optimise your lithium-ion batteries’ performance and service life, our BTMS uses an intelligent controller to precisely manage your vehicle’s battery, we monitor the cell temperatures and instantly respond with heating or cooling mode.

Our sophisticated GTS-designed software ensures minimal power draw while delivering maximum performance, and the system’s market-leading design and various configurations means seamless integration with your application.

The advanced BTMS for your next-generation vehicle

Your next-generation zero-emission vehicle requires a next-generation thermal management system capable of maximising your batteries’ efficiency and service life.

As pioneers in battery temperature regulation, we have been working closely with OEMs and battery suppliers across a variety of sectors to continuously enhance our BTMS range.

In series production since 2015, our solutions are now the proven system of choice for many leading global manufacturers, providing constant accurate temperature regulation in the most extreme of climates.
