Coolant Valves for commercial vehicles

Coolant valves for electric vehicles, fuel cell vehicles and other applications

Complex cooling architecture incorporates coolant valves within the system to regulate and zone coolant flow for electric vehicles (EVs) or fuel cell vehicles (FCVs). Coolant valves can direct coolant towards the battery when operating at high temperatures and allow for quicker heating when the battery is cold by reducing the coolant volume being heated and prioritising key components. These dynamic changes in architecture allow system priorities to be managed through the control system.

Cooling valves are essential for the cooling architecture system

Our range of cooling valves includes the 3-way proportional valve, an essential part of the cooling architecture system for EVs and FCVs. Its 3-way configuration is designed to efficiently direct high flowrate coolant to multiple pathways, such as the heat exchanger or bypass, depending on the application’s cooling requirements. Fuel cell valves are typically designed for low coolant pressure drop, ensuring the system operates at peak efficiency. The valve is CAN-controlled, further enhancing its functionality.

The shut off valve, a key part of the cooling system, opens or closes during the driving / charging cycle. Prioritising the onboard charger sub-circuit is crucial by isolating it from the main coolant loop in a charge cycle. This technique significantly reduces stress on the coolant pump and minimises energy consumption, contributing to the system’s overall efficiency. By zoning the cooling system, unnecessary flow is not sent to the driveline when stationary and charging.
