Technotrans to present cybersecurity-ready BTMS at Busworld

German components supplier Technotrans announceas it will present its new battery thermal management system (BTMS) zeta.trax for on-road and off-road vehicles for the first time at this year’s Busworld in Brussels. The new system is said to be “cybersecurity-ready, fulfilling a key requirement for the type approval of new vehicle models. Thanks to its high-voltage connection, the system enables significant cost and complexity reductions for vehicle manufacturers”, in the supplier’s words.

In addition, technotrans will showcase energy-efficient cooling solutions for charging infrastructure. The company operates with passive cooling, without active compression refrigeration. Typical applications include power electronics in charging infrastructure.

In early 2025 Technotrans announced a follow-up BTMS order from e-bus manufacturer, as the first order was made public in May 2024. 

Technotrans to release new generation BTMS

Focusing on Technotrans zeta.trax BTMS, in addition to the 24-volt DC connection, it offers the option of direct connection to the high-voltage vehicle electrical system in the voltage range of 500 to 850 volts DC. This allows vehicle manufacturers to dispense with additional components for voltage conversion, resulting in reduced system complexity, installation space requirements, and overall costs, Technotrans says.

The base version of the new unit is designed for a cooling capacity of 6 kW, but can be scaled to meet higher performance requirements. Furthermore, the new cooling system is optionally available with a low global warming potential (low-GWP) refrigerant, ensuring manufacturers are well-prepared for future tightening of legal regulations.

“With our new solution, we are taking BTMS to the next level and addressing the core challenges faced by vehicle manufacturers: regulatory compliance, cost-effectiveness, and sustainability,” says Jan Kühne, Business Development Manager at technotrans. “The cybersecurity architecture provides the necessary security for new type approvals. At the same time, we have designed the system to significantly reduce integration effort and costs for our customers.”
