BALANCING THE ‘DOMINOS’ in EV thermal management

Excessive internal valve leakage is an inefficiency that worsens upstream system inefficiencies. Effective valve design is the solution.

Electric vehicle thermal management requires OEMs and suppliers to control many variables that potentially create excessive heat. Designing thermal-management systems (TMS) to effectively control these variables is critical to overall EV performance. Internal leakage and other coolant-valve performance criteria are among the variables affecting EV performance, most notably driving range. Valve design is fundamental to a robust, thermally efficient and leak-free system, according to engineers at Robertshaw Controls, a specialist in plastic coolant-valve innovation and TMS design.
