Hella reveals new subsystem for thermal management in electric vehicles

Hella announces new product for a more efficient thermal management in electric vehicles, as manufacturers are looking for ways to make the best possible use of the heat energy generated and to reduce the complexity in the coolant circuit.

“One key to successful electrification is efficient thermal management,” says Björn Twiehaus, Managing Director responsible for HELLA’s global electronics business. “With the Coolant Control Hub, we are therefore now launching an innovative subsystem that revolutionizes thermal management in the vehicle.”

Hella’s Coolant Control Hub (CCH) is based on a modular principle and, in its highest level of integration, connects three circuits with each other in the vehicle: the battery, interior electronics as well as the power electronics and electric motor circuit. “What they all have in common is a significant reduction in components, which means that logistics and overall costs for installing the vehicle can be reduced – a major advantage for manufacturers,” says Twiehaus.

Hella has implemented an advanced valve concept based on its high level of system expertise in the areas of fluidics, engines, electronics and software, as well as its interfaces with the cooling- and refrigerant system and its many years of know-how in high-performance electric pumps and actuators. The innovative 7-way valve, for which a patent is already pending, makes it possible to achieve ideal heat recovery and thus increase efficiency. In short, this helps distribute heating or cooling demand for the vehicle’s critical components as needed, resulting in improved thermal performance.
