Thermal management specialist Technotrans will debut its new battery thermal management system (BTMS) zeta.trax at this year’s Busworld exhibition in Brussels, marking the first public presentation of the company’s latest cooling technology for EVs.
The zeta.trax system addresses key challenges facing vehicle manufacturers, including regulatory compliance requirements and cost reduction needs. A primary feature of the new system is its cybersecurity architecture, designed to meet emerging type approval requirements for new vehicle models.
The system offers both standard 24-volt DC connection and direct high-voltage connection capability, supporting voltages between 500 and 850 volts DC. This high-voltage option allows vehicle manufacturers to eliminate additional voltage conversion components, reducing system complexity, space requirements, and overall integration costs.
“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.”
The zeta.trax is designed for both on-road and off-road battery-electric applications. The base configuration provides 6 kW of cooling capacity, with scaling options available for higher performance requirements. The system can optionally use low global warming potential (low-GWP) refrigerant, positioning manufacturers to comply with anticipated future environmental regulations.
Beyond vehicle applications, Technotrans will also demonstrate cooling solutions for charging infrastructure at Busworld. These stationary systems utilize passive cooling technology without active compression refrigeration, making them more energy-efficient than conventional alternatives. The systems are designed for power electronics in various charging infrastructure applications.
The company’s focus on both mobile and stationary cooling solutions reflects the growing demand for thermal management across the electric vehicle ecosystem. As battery capacities increase and charging speeds accelerate, effective thermal management becomes increasingly critical for performance, safety, and longevity.
The zeta.trax represents Technotrans response to the evolving regulatory landscape for EVs, particularly regarding cybersecurity requirements that are becoming mandatory for type approvals in various markets. The system’s modular design and voltage flexibility aim to simplify integration for vehicle manufacturers while reducing costs and complexity in electric vehicle development.
