Generated energy is power battery module (2) charging, is full of until by power battery module (2) electricity, and then dynamical system controls mould
Block (4) controls fuel cell module (1) and stops power supply outward；
Wherein method for electrically includes the following steps: under electrical vehicular power
For electric vehicle after parking shutdown, powertrain control module (4) acquires the residue electricity of power battery module (2) offer in real time
Measure data:
When acquiring remaining capacity data and being less than the remaining capacity threshold value B of powertrain control module (4) inner setting, then power
System control module (4) issues control signal to Fuel Cell Control management module (14), and control fuel cell module (1) continues
Power supply outward is charged for power battery module (2), is full of until by power battery module (2) electricity, and then dynamical system controls
Module (4) controls fuel cell module (1) and stops power supply outward.
