[0035] figure 1 A flow chart of an energy management method for a pure electric vehicle provided by the present invention is shown, and the details are as follows:
[0036] In step S1, after the car is started, the vehicle controller installed on the car performs initialization processing.
[0037] Step S2, after the vehicle controller has been initialized, determine whether the driver of the vehicle is using the defrosting and defogging functions for the vehicle controller, and if so, ensure the defrosting and defogging functions If the power requirement of the high-voltage auxiliary parts is not met, go to step S3.
[0038] Step S3, judging whether the whole vehicle mode is the braking energy feedback mode; if it is the braking energy feedback mode, it is necessary to determine whether the driver's demanded braking force is greater than the maximum electric braking force, and if it is greater than the maximum electric braking force, then the driver's demand The braking for...
