306, if not, waiting BMS to be waken up.
If the guard mode of BMS is unchanged and is continued above setting time threshold value, in an embodiment of the present invention, described
It is 1 minute that whether the guard bit unchanged time exceedes setting time threshold value, BMS automatically into low-speed mode, BMS for a long time at
In under low-speed mode, now, BMS is that in a dormant state, in order to fully reduce power consumption, MCU is into needing to close BMS phases before dormancy
Powered-down source and MCU pin functions are reconfigured, such as：Close amplifier power supply, voltage detecting and enable pin, the voltage closed inside MCU
Adjuster and make MCU inside FLASH power down, reduce BMS power consumptions, under park mode BMS set MCU inside automatically waken up mould
Block, for example, set a wakeup time threshold value, in an embodiment of the present invention, the BMS the wakeup time threshold value for setting as
1 second, if reaching wakeup time threshold time wakes up MCU RTC clock wake-up mechanisms once, waking up also included outside setting
Portion interrupts and wakes up, therefore, the wake-up mechanism includes two kinds：External interrupt wakeup and system are automatically wakened up.MCU is after waking up
Corresponding treatment should be done, because in the hibernation mode, being closed during the TICK counters of system, timer stops work
Make, only low speed RC oscillators are in work, so the TICK timers of system should be readjusted after being waken up under park mode
Calculated value, prevents TICK timers inaccurate, therefore, BMS timing will add the time during dormancy, can otherwise cause TICK to count
When it is inaccurate, influence system timing function.
The MCU is STM8S003F2 chips using chip.
