Whether pressure condition is forceful electric power condition adjudgement step in second of upper forceful electric power state；H. can be same in third time perceives judgment step
When meeting in the case of two Rule of judgment, judge whether current high pressure conditions are strong in the third time of upper forceful electric power state again
Electricity condition judgment step；I. on being judged as on first time in forceful electric power condition adjudgement step in the case of forceful electric power state, into putting
PDU interior humidity pre-warning signals put 1, and keep the early warning of current upper forceful electric power state and keep upper forceful electric power step；J. at second
In the case of being judged as upper forceful electric power state in upper forceful electric power condition adjudgement step, 1 is put into PDU interior humidity alarm signals are put, and
Keep the alarm of current upper forceful electric power state and keep upper forceful electric power step；K. it is judged as in third time in forceful electric power condition adjudgement step
In the case of upper forceful electric power state, 1 is put into the serious alarm signal of PDU interior humidities is put, and asks lower forceful electric power signal to put 1, and is opened
Dynamic high pressure voluntarily descends forceful electric power timing to start, and the forceful electric power in the case where voluntarily descending the forceful electric power time more than setting high pressure then PDCU voluntarily being forced
Force lower forceful electric power step；M. it is judged as on first time in forceful electric power condition adjudgement step on not in the case of forceful electric power state, enters
Put PDU interior humidity pre-warning signals and put the early warning and upper forceful electric power request step that forceful electric power is asked in 1, PDCU response externals；N.
In the case of being judged as not upper forceful electric power state in secondary upper forceful electric power condition adjudgement step, into putting PDU interior humidity alarm signals
Put the alarm that forceful electric power is asked on 1, PDCU refusals and refuse upper forceful electric power request step；O. the forceful electric power condition adjudgement step in third time
In be judged as not upper forceful electric power state in the case of, put into the serious alarm signal of PDU interior humidities is put on 1, PDCU refusals outside
The serious alarm of forceful electric power request simultaneously refuses upper forceful electric power request step；P. any one in i-th, j, k, m, n, o step is completed
After step, enter and continue to repeat the above detection senses information data read step described in a steps；In above-mentioned steps
V1 and V2 be represented as respectively：The total face vehicle body voltage V1 of high pressure and high pressure are always negative to vehicle body voltage V2；PDU implications are high pressure energy
Measure distributor；PDCU implications are high-pressure energy dispensing controller.
9. perceive the high voltage power distribution implementation method with early warning, its feature with humidity and dielectric strength according to described in claim 8
It is：Described detection senses information data read step includes PDCU high voltage power distributions controller and reads following data：Dielectric is strong
Degree auxiliary detection module, the total face vehicle body ground voltage V1 of high pressure, high pressure are always negative to vehicle body ground voltage V2, moisture sensor module
PDU internal environments humidity data and outside upper forceful electric power request instruction.
