Electric vehicle thermal management

Abstract

An electric vehicle thermal management system includes a battery unit, an electric drive unit; a heat exchanger; a crossflow valve unit; and a coolant network for supplying coolant to the battery unit, the electric drive unit, the heat exchanger and the crossflow valve unit. The crossflow valve unit is configured to control coolant flow through the coolant network by, in a parallel-loop operating mode, partitioning the coolant network into two parallel network configurations, the two parallel network configurations including a first coolant circulation loop including the battery, and a second coolant circulation loop including the electric drive unit and the heat exchanger. The crossflow valve unit further includes a communication port to permit coolant flow between the first and second coolant circulation loops when there is a pressure differential between coolant flow through said first and second coolant circulation loops.
