The working principle of all the period of time monitoring, wherein all the period of time of the present embodiment includes that vehicle is in driving states, vehicle is in parking and fills
Electricity condition and vehicle are in three kinds of storage configuration of parking:
One, driving states:
After ON gear switch 52 is closed, i.e. effectively, the battery management system 10 wakes up work to ON grades of electricity, into driving mould
The status information of collected power battery is sent to vehicle CAN by formula, battery management system 10, the Train-borne recorder 40 from
Vehicle CAN collects the status information of power battery, then by built-in wireless communication module be sent to monitor supervision platform (such as
It is sent by way of GPS).Battery management system 10 controls the second relay K2 closure simultaneously, connects the vehicle-mounted DC/DC and turns
The low-voltage supply of parallel operation 20, control the first relay K1 closure, the high pressure for connecting the vehicle-mounted DC/DC converter 20 are defeated
Enter, then sends starting message and start vehicle-mounted DC/DC converter 20, the vehicle-mounted DC/DC converter 20 will be received next automatic
After the high input voltage of power battery 30 is converted to low-tension supply, low-tension supply is provided to vehicle, and charge to the starting battery 51.
After ON gear switch 51 is closed, ON grades of electricity are invalid, and the battery management system 10 sends the report for stopping vehicle-mounted DC/DC converter 20
Text, the vehicle-mounted DC/DC converter 20 stop working, and the battery management system 10 controls the first relay K1, the second relay
Device K2 is disconnected, subsequently into standby dormant state.
Two, under charged state
For vehicle when being charged, off-board charger can export 1 A+ (12V) low pressure accessory power supply, when A+ is effective
Afterwards, the battery management system 10 wakes up work, into charge mode.Battery management system 10 is by collected power battery
Status information is sent to vehicle CAN, and the Train-borne recorder 40 collects the status information of power battery from vehicle CAN, then

The low-voltage supply of the vehicle-mounted DC/DC converter 20 is connected, control the first relay K1 closure connects the vehicle-mounted DC/
Then the high input voltage of DC converter 20 sends starting message and starts vehicle-mounted DC/DC converter 20, the vehicle-mounted DC/DC conversion
After the received high input voltage from power battery 30 is converted to low-tension supply by device 20, low-tension supply is provided to vehicle, and give
The starting battery 51 charges.After charging electricity, off-board charger stops output, and A+ is invalid, the battery management system
10 send the message for stopping vehicle-mounted DC/DC converter 20, and the vehicle-mounted DC/DC converter 20 stops working, the battery management
System 10 controls the first relay K1, the second relay K2 and disconnects, subsequently into standby dormant state.
Three, stop storage configuration
When ON gear switch 52 disconnects and is uncharged, i.e. when A+ is invalid, ON grades all invalid, built in battery management system 10
RTC circuit 11 starts timing, as the dormancy time T1 (being such as set as 1 hour) for reaching setting, wakes up 10 work of battery management system
Make, the status information of collected power battery 30 is sent to vehicle CAN by battery management system 10, and Train-borne recorder 20 is from whole
The status information that vehicle CAN collects power battery is sent to monitor supervision platform.Battery management system 10 controls the second relay K2 and closes
It closes, connects the low-voltage supply of vehicle-mounted DC/DC converter 20, control the first relay K1 closure connects vehicle-mounted DC/DC conversion
Then the high input voltage of device 20 sends starting message and starts the vehicle-mounted work of DC/DC converter 20, gives battery management system 10, vehicle
It carries recorder 20 and low-tension supply is provided, and charge to the starting battery of vehicle.When the working time T2 for reaching setting (is such as set as
5 minutes), hair stops message and stops working to vehicle-mounted DC/DC converter 20, and the first relay of control K1, the second relay K2 is disconnected
It opens, into standby dormant state, after reaching the dormancy time T1 of setting again, the battery management system 10 reawakes work
Make, recycles according to this.
Wherein, during vehicle parking storage, vehicle-mounted 20 maximum operating currenbt of DC/DC converter is 200A, is much larger than
The standby suspend mode power consumption of the battery management system 10, the vehicle-mounted DC/DC converter work 5 minutes, can fill to battery is started
Electric 16Ah, it is ensured that 10 standby suspend mode of battery management system 1 year wakes up work T2=5min, setting according to every T1=1h
Parking storage from wake-up period, vehicle launch battery capacity not only can satisfy the standby power consumption of battery management system 10 balance,
Realize all the period of time monitoring system, but also can fully ensure that the electricity of vehicle launch battery, avoid parking cars for a long time and
Caused starting battery supply feed and do not start vehicle condition.
It should be noted that in the other embodiments of invention, can be arranged according to actual needs the dormancy time and
Working time, and be not limited to the above-mentioned numerical value referred to, these schemes are also within protection scope of the present invention.
In conclusion the new-energy automobile power battery all the period of time monitoring system of the present embodiment, by the cell tube
RTC circuit 11 built in reason system 10, and timing wake-up cell tube during parking is stored is in vehicle by RTC circuit 11
Reason system 10 carries out working condition from dormant state, so that vehicle can also be normally carried out the shape of power battery during storage of stopping
State monitoring.It, can there are high-voltage loads often to connect power battery height to avoid vehicle in addition, by configuring vehicle-mounted DC/DC converter 20
It pressure bring risk and works on power always there are high-voltage load and bring security risk is asked during vehicle parking storage
Topic.Meanwhile vehicle is also solved after long term stop storage, because what vehicle launch battery supply feed had led to vehicle launch not asks
Topic.
