Technotrans, a Germany-based thermal management company, has announced a new battery thermal management system (BTMS) for battery electric on-road and off-road vehicles called zeta.trax.
The BTMS is said to have the option for a direct connection to the high-voltage vehicle electrical system in a voltage range of 500-800V DC in addition to a 24V DC connection.
With zeta.trax, vehicle manufacturers do not need extra components for voltage conversion, which the company said can lead to reduced system complexity.
The base version of the BTMS is designed for a cooling capacity of 6kW but can be scaled for higher performance requirements. The cooling system has an optional low global warming potential refrigerant. It has cyber security features and meets requirements for new type approvals of electric buses.
The company said its battery management systems operate with passive cooling, without active compression refrigeration, making them energy efficient.
Applications can include stationary solutions, such as power electronics in charging infrastructure.
“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, Technotrans. “The cyber security 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.”
