Infineon's comprehensive thermal management portfolio for electric vehicles includes in-cabin refrigerant circuit (HVAC systems), battery cooling and heating systems, and inverter cooling systems. Additionally, we provide integrated thermal management systems, which are more commonly used by OEMs that converge on liquid-based battery cooling strategies.
Thermal management plays a crucial role in battery electric vehicles (BEV) due to the minimal heat generated by their electric motors. This poses challenges in maintaining optimal temperatures, requiring additional heating for passenger comfort at the expense of reduced range. Fast charging further drives the need for precise thermal management in electric vehicles. As many network providers offer DC fast charging stations with up to 350 kW of power, the batteries must operate within a narrow temperature window to maximize charging power.
Effective electric vehicle thermal management prevents issues like demagnetization, aging of insulation materials, decreased efficiency, and even motor burnout. It also enhances battery longevity and serves as a safety feature against thermal runaway in electric vehicles.

Optimize performance and range with EV cooling technology
Infineon’s scalable EV thermal management system solutions can be categorized in three main categories which offer full flexibility with system-dedicated products.
The cabin HVAC thermal circuit provides thermal comfort for passengers and consists of the refrigerant loop and the HVAC loop.
The inverter cooling system is crucial for maintaining the efficiency, durability, and safety of the electric motor. As the automotive industry shifts toward electrification, the challenges associated with thermal management for power electronics and electric motors increase due to the need for compact size, cost-effectiveness, reduced weight, and uncompromised performance and reliability.
Furthermore, battery cooling and heating systems are of paramount importance. Keeping the batteries cool helps increase the longevity of the cells but is also a major safety feature to prevent thermal runaway. This means that the thermal management of batteries is a key consideration for the range, performance, and safety of electric vehicles - they are cooled or heated by means of electric coolant pumps, coolant valves, cooling fans and electric/PTC heaters.
The microlearning has an application focus on auxiliary pumps and fans. It will give an overview of the application requirements of pumps and fan applications. In detail the key challenges of engine cooling fan, fuel pump, and oil pumps are shown and how those can be solved with Infineon’s highly-integrated system-on-chip solution.
