Abstract
In one aspect, the present disclosure is directed to a method for controlling operation of an electric water pump configured to circulate a cooling fluid. The method may include detecting a startup of an electric power source associated with the electric water pump. In addition, the method may include monitoring a voltage available to the electric water pump in response to the detected startup of the power source. The method may also include providing an activation signal to the electric water pump if the monitored voltage is equal to or greater than a first threshold voltage.
