S5: the cell operating status of power battery is obtained, and according to the cell operating status and the absolute time meter
It calculates and obtains the lower electric time of battery.
Specifically, it by the way that time effective marker position is arranged on TBOX, is obtained when time effective marker position is 1 by TBOX
Accumulative power-on time is taken, failure is obtained by the MCU progress timing in entire car controller when time effective marker position is 0 and is added up
Power-on time, and then the lower electric time of vehicle is obtained, it remains to calculate vehicle accurately lower electricity in TBOX failure stage to realize

State the sum of difference.
In practical applications, if TBOX fails and restores in this power up: record TBOX powers on initial time T0,
Cumulative time t1 is powered on before TBOX failure, and is opened MCU clocking capability after Tbox failure and recorded MCU cumulative time △ t.When
TBOX records current time T2 after resuming work, then T0+t1+ △ t and T2 can be carried out mutual calibration, with t1 if deviation is larger
+ △ t is as the accumulative power-on time before Tbox recovery, and note t2 is the power-on time after TBOX recovery normally to electricity under this, then T
=(t1+ △ t)+t2.
If TBOX fails in this power up, restores in next power up: recording this and power on initial time
Accumulative power-on time t1 before T0, TBOX failure, and open the timely function of MCU after Tbox failure and record MCU cumulative time △ t,
Then adding up power-on time in this power up is t1+ △ t.MCU cumulative time △ t2 is continued starting after powering on next time, instantly
It is secondary to power on rear TBOX recovery and then record current time T2, and remember that adding up power-on time after TBOX restores is t2, then next time powers on
Accumulative power-on time is △ t2+t2.The total power-on time powered on twice is T=(t1+ △ t)+(△ t2+t2).
If TBOX fails in this power up, and does not restore in next power up: recording this and power on initially
Accumulative power-on time t1 before time T0, TBOX failure, and open the timely function of MCU after TBOX failure and record the MCU cumulative time
△ t1, then adding up power-on time in this power up is t1+ △ t.MCU cumulative time △ t2 is continued starting after powering on next time
Until lower electricity, and so on third time to power on the cumulative time be △ t3, n-th powers on cumulative time △ tn.Then restore in TBOX
Accumulative power-on time before is T=t1+ △ t1+ △ t2+ △ t3+ ...+△ tn.
