Thermal Management System, Vehicle And Method For Operating Two Cooling Circuits Of A Thermal Managment System

Patent No. EP3999367 (titled "Thermal Management System, Vehicle And Method For Operating Two Cooling Circuits Of A Thermal Managment System") was filed by Schaeffler on Jul 16, 2020. The application was issued on Sep 10, 2025.

Patent Summary

A vehicle thermal management system comprises a first cooling circuit for a battery and a second cooling circuit for an electric motor and power electronics. A multi-way valve connects these circuits in series during a first mode (first valve position) or in parallel during a second mode (second valve position). In a third mode, the multi-way valve assumes an intermediate position to enable demand-based mixing of the two coolant flows to optimize temperature control. The multi-way valve may be a 5/3-way valve fluidically connected to a radiator path and a bypass path originating from a node downstream of the electric motor. The system is operated via a method and computer program executing temperature-monitoring-based control.
