"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."
"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."
Technotrans will present the zeta.trax battery thermal management system (BTMS) for on-road and off-road vehicles at Busworld in Brussels. The system is cybersecurity-ready and supports a direct high-voltage DC connection (500–850 V), reducing the need for voltage conversion components and lowering system complexity, installation space and costs. The zeta.trax includes a 24 V option and a base 6 kW cooling capacity scalable to higher performance. An optional low-GWP refrigerant is available to meet tightening regulations. Technotrans also offers passive, energy-efficient cooling solutions for charging infrastructure power electronics. A follow-up BTMS order from an e-bus manufacturer was announced in early 2025.
