The monitoring controller is also used to before judging whether first timer reaches the first setting time, described in judgement
Un-activation flag bit whether set；If it is, removing un-activation mark after first timer reaches third setting time
Will position exports the first level by rigid line to activate entire car controller, and continue to fill to entire car controller transmission by CAN bus
Electricity instruction；Otherwise, judge whether first timer reaches the first setting time；The third setting time is less than described the
One setting time.
8. automobile storage battery timing charging system according to claim 7, which is characterized in that the monitoring controller is
After one timer starts timing, real-time detection vehicle-state, when detecting vehicle-state is starting state or charged state, control
It makes the first timer and restarts timing.
