Thermal management plays a critical role in the performance of electric vehicles and, when harnessed with the right technology, even holds the potential to give electric vehicles more mileage per charge. But EV thermal management comes with its own challenges.
To keep up with changing flow requirements in an EV cooling system and to maintain optimal component temperatures, the cooling system ideally needs proportional control. A valve to control this proportional flow would need to feature zero hysteresis and zero steady-state power at any setpoint, include a leak-free off state, and also contain a fail-safe condition for when power is lost.
No valve featuring all of these capabilities existed until last year. In early 2019, TLX Technologies, a creator of customized electro-mechanical solenoid products, designed and introduced the Discrete Proportional Valve (DPV).
