T-BOX issues " mend electricity " request and wakes up BCM, powers on after BCM response to VCU, in detection vehicle mounted dynamic battery voltage value and other
After condition all meets, DC-DC converter is opened to charge to Vehicular accumulator cell.Charging setting time to judging ignition relay,
" mending electricity " process terminates.
It is as follows that " mending electricity " process can be described in detail by Fig. 4:
Time interval of the T-BOX according to setting, timing wake-up BCM test supply voltage, this voltage value is exactly battery electricity
This voltage value is transmitted to T-BOX simultaneously by pressure, BCM, judges whether this voltage value needs to carry out " mending electricity " operation by T-BOX, such as
Fruit does not need to carry out mending electricity, then allows TBOX to enter dormant state, if T-BOX judgement carries out mending electricity, can issue to BCM
Electricity request is mended, these information are communicated by vehicle CAN network.BCM enters " mending power mode " after receiving benefit electricity request.
BCM is powered on to vehicle, but can issue " mending electricity " information simultaneously, so that system without interaction (such as instrument, large-size screen monitors, light, air-conditioning etc.)
It does not work, while VCU starts to detect power battery situation, such as battery capacity SOC, whether power battery is in charging etc., such as really bar
Part meets, then opens DC-DC controller, so that the high pressure of power battery charges after DC-DC is depressured to Vehicular accumulator cell, at this time
VCU issues " mend electricity success " information, and BCM starts to charge timing, when setting time to after BCM shutdown vehicle supply relay,
It is simultaneously emitted by " mending electricity to complete " information, BCM enters dormant state.TBOX is opened again after receiving " mending electricity to complete " information that BCM is issued
Beginning reclocking, timing wake-up BCM detect battery voltage, act into " electricity is mended " next time.
