A cooling system for a hybrid vehicle comprises an indirect charge air cooler and an electro-cooler, the charge air cooler and the electro-cooler each in fluid communication with a common low temperature radiator. The cooling system comprises at least one pump for circulating fluid around the radiator and the charge air cooler and the electro-cooler, at least one fan having a variable speed motor associated with the low temperature radiator and configured to cause air to pass through the low temperature radiator, a controller and a plurality of sensors. The plurality of sensors includes a sensor for sensing the coolant fluid temperature at the outlet of the charge air cooler and a sensor for sensing the coolant fluid at the outlet of the electro-cooler. The variable speed motor of the at least one fan and the variable speed motor of the at least one pump are each connected to the controller, and the controller is configured to adjust the respective speeds of the variable speed motor of the at least one pump and the variable speed motor of the at least one fan according to the temperatures recorded by the temperature sensors and preset threshold temperatures. |
