step 201: detecting the residual electric quantity percentage SOC of the power battery, the capacity retention rate K of the power battery and the nominal total electric quantity Q of the power battery B The method comprises the steps of carrying out a first treatment on the surface of the Detecting residual mass M of hydrogen fuel H Hydrogen-to-electricity conversion η 1 The method comprises the steps of carrying out a first treatment on the surface of the Detecting energy consumption eta of the hybrid electric vehicle per kilometer 2 。
Wherein, the nominal total electric quantity Q of the power battery B To a known extent, Q can be obtained according to the type or configuration of the car B Is in kwh; the capacity retention rate K of the power battery is a matrix and is embodied in the form of percentage; residual mass M of Hydrogen Fuel H Is in g; hydrogen-to-electricity conversion rate eta 1 Is given in kwh/g; energy consumption eta of hybrid electric vehicle per kilometer 2 In kwh/km.
The vehicle may check the above parameters by an internal sensor, and the specific detection method is not limited in this application, and may be detected by no sensor.
