The on-off line operation of circuit between charger and high-tension battery, high-tension battery and DC/DC converters.
A kind of vehicle-mounted A-battery of the utility model is mended controller for electric consumption advantage and is：
The device of the utility model is the intelligent charging conversion all-in-one machine for integrating OBC and DC/DC converters, effectively
Ground reduces equipment overall volume, and realizes intelligent without darning electric control.When driving, DC/DC is used as energy conversion；And
While OBC charges to high-tension battery, DC/DC is used as intelligence benefit and supplies electricity to A-battery, prevents A-battery power shortage.This control
Strategy effectively meets client to miniaturization, integrated demand, simultaneously effective solves the problems, such as A-battery power shortage.
Automobile vendor is adapted to for device miniaturization, integrated active demand, while it is long to compensate for whole-control system well
Time loss A-battery electricity, prevents A-battery power shortage, causes the problem of the starting that cannot light a fire；To reach intelligent section
Damage, the purpose for mending electric A-battery.
Description of the drawings
Fig. 1 is that a kind of vehicle-mounted A-battery provided in the utility model embodiment mends controller for electric consumption structural schematic diagram.
Specific implementation mode
Technical solution provided by the utility model is further illustrated with reference to embodiments.
As shown in Figure 1, a kind of vehicle-mounted A-battery provided by the utility model mends controller for electric consumption, including：Battery management
System（Abbreviation BMS）, Vehicular charger（Abbreviation OBC）, intelligent controller and DC/DC converters；The Vehicular charger, intelligence
The data transmission terminal of energy controller, DC/DC converters and battery management system is sequentially communicated, the battery management system and vehicle
Data communication is realized by the CAN bus of setting between load charger；The electric energy output end and high-voltage electricity of the Vehicular charger
The electrical energy inputs in pond connect, the electrical energy inputs and electric energy output end of the DC/DC converters be separately connected high-tension battery and
A-battery, for realizing the conversion of high-low pressure electric energy, or by the electricity of intelligent controller monitoring A-battery, with control
DC/DC converters carry out A-battery to mend electricity.
Device based on above structure, as shown in Figure 1, in the present embodiment, the Vehicular charger and high-tension battery,
Contactor, the control that the contactor passes through reception battery management system are also provided between high-tension battery and DC/DC converters
Signal processed executes the on-off line operation of circuit between Vehicular charger and high-tension battery, high-tension battery and DC/DC converters.
In the present embodiment, the specific mistake that controller for electric consumption carries out charge control operation is mended using above-mentioned vehicle-mounted A-battery
Journey is divided into following two steps：
1, OBC charged states control sequential：
After charging gun grafting is errorless, alternating current AC220V accesses OBC, and OBC inside chips start, while enable signal EN1
It is uploaded to intelligent controller, intelligent controller assigns EN1-1 signals to DC/DC converters, and DC/DC converters then export BMS+
To BMS systems, BMS assigns CAN communication and instructs to OBC, driving OBC to be started signal, starts to charge to HBAT high-tension batteries.
During this, BMS and OBC carries out real time data interaction by CAN bus.
During OBC charges to HBAT high-tension batteries, intelligent controller monitors the voltage of LBAT A-batteries in real time, when
When LBAT brownouts, intelligent controller can give DC/DC converters by assigning intelligence benefit electricity instruction, realize DC/DC converters
Intelligence mends electricity LBAT functions, prevents A-battery power shortage from cannot light a fire.
2, DC/DC high-low pressures energy conversion timing sequence：
After entire car controller assigns DC/DC activation signal DCACT, DC/DC converters are activated, and DC/DC is reported to BMS
One CAN request instruction, then BMS assign a CAN grant instruction, DC/DC converters start at this time, start to realize by high pressure
The energy of battery is converted to A-battery.During this period, DC/DC converters and BMS real time interactive operations are complete by CAN bus
At.
It should be noted last that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application.To the greatest extent
Pipe is described in detail the utility model with reference to embodiment, it will be understood by those of ordinary skill in the art that, to this practicality
Novel technical solution is modified or replaced equivalently, without departure from the spirit and scope of technical solutions of the utility model,
It should all cover in the right of the utility model.
