Thermal management is the capacity to control the temperature of a system and its subsystems, such as the interior, battery, and engine of an electric vehicle. This system requires an adequate coolant flow controller to turn off the coolant flow, regulate the coolant flow, and switch between coolant circuits. This engine coolant flow valve may speed up cabin warming by first sending heat to the heat exchanger core. Additionally, it permits a decrease in coolant flow for an ideal engine temperature.
