It is input to cooling line (as shown in the arrow head part in Fig. 1), cooling medium flow process in cooling line through valve 103
The heat that middle other assembly of absorption electric automobile (the most aforesaid traction electric machine, traction motor controller etc.) distributes, then leads to
Cross radiator 104 and cooling line is realized cooling.Cooling line may be constructed loop so that cooling medium can be at cooling line
In circulate.On the other hand, radiator 104 can be utilized by Duct design to electric automobile by the way of air-cooled
Other parts and other assembly cool down.
More specifically, pump 102 is powered by battery 500, and it is controlled by vehicle control device (VCU).Vehicle control device can
To control the power of pump 102 so that pump 102 becomes the pump of power adjustable, thus the power first passing through control pump 102 adjusts
