Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, below in conjunction with the accompanying drawings to the present invention
Embodiment be described in detail.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still the present invention can be with
It is different from other manner described here using other to implement, therefore the present invention is not limited by following public specific embodiment
System.
In the present invention, it is proposed that electric control method under a kind of charger, pass through onboard charger or fast for electric car
Fast charger is the lower electric control in battery bag charging process, including：Obtain the status information of charging gun；Believe in charging gun state
When ceasing not extract, battery bag charging status information is obtained；When battery bag electricity condition information is fully charged, charger is obtained
Output current；When the output current of charger is zero, cut-out charging wake-up signal；Storage battery bag charging status information.
In the present invention, the output electricity of the status information of charging gun, battery bag charging status information and charger is passed through
Stream, judges the working condition of charging gun step by step, and records battery bag charging status information, improves to charging gun power-down state
Effectively management, avoid unexpected lower information caused by electricity from losing, improve the accuracy of battery management system strategy, and then improve whole
The reliability and security of individual battery system.
In order to be better understood from technical scheme and technique effect, below with reference to specific embodiment and flow
Schematic diagram is described in detail.
As shown in figure 1, first, in step S01, into charge mode.
When charging gun enters charge mode, charging gun is connected in mains-supplied network, and now, charger sends charging
Wake-up signal, the charging wake-up signal are level signal, are usually sent to entire car controller unit, and entire car controller unit receives
To after the charging wake-up signal, that is, think that battery bag enters charge mode, charging gun has been connected to power inlet.
Then, in step S02, the status information of charging gun is obtained.
Can be charged wake-up signal by acquisition, to obtain the status information of charging gun, when the wake-up signal that charges is effective,
The status information of charging gun is does not extract, and when the wake-up signal that charges is invalid, then the status information of charging gun is to have extracted.
When the status information of charging gun is does not extract, then continue to obtain battery bag charging status information, into step
S03。
When the status information of charging gun is has extracted, then into step S06, the storage of battery bag data is carried out, now,
The data of the battery bag of storage include the parameters such as dump energy (SOC) and/or the cell health state (SOH) of battery, the data
It can obtain and store into EEPROM by battery management unit, in order to permanently storing for data, and after a power failure, electricity
Pond administrative unit or other units still can carry out extraction and further application to the data.
Then, in step S03, battery bag charging status information is obtained.
The charging status information of battery bag can be obtained by battery management unit, the charging status information of battery bag is
Whether battery bag is fully charged, and in charging process, battery management unit persistently obtains the voltage of the battery cell in battery bag, if
The voltage of battery unit cell reaches threshold voltage, then it is assumed that battery bag has been filled with electricity, otherwise it is assumed that battery bag underfill is electric.Should
The charging status information of battery bag can be sent to by battery management unit by way of CAN communication entire car controller or other
Processor unit.
In this step, battery bag charging status information is persistently obtained, until the charging status information of battery bag is battery
Bag has been filled with electricity.
Then, in step S04, the output current of charger is obtained.
After the information that the battery bag got has been filled with electricity, continue to obtain the output current of charger, using car
When load charger is charged, the output current of onboard charger is obtained, when being charged using quick charger, is obtained fast
The output current of fast charger, when the output current of charger is zero, then it is considered that battery bag has been filled with electricity and charger
State it is normal, in this case, safe lower electric control operation can be carried out.Common, battery management unit can obtain this
The output current of charger, it can be exported by current sensor to battery management unit to obtain, battery management unit passes through
The mode of CAN communication sends the current information to entire car controller or other processor units.
Then, in step S05, cut-out charging wake-up signal.
When the output current of charger is zero, cut-out charging wake-up signal, i.e., the charging wake-up signal of charger is set
It is invalid to be set to.
Then, in step S06, storage battery bag charging status information.
Now, the battery bag data message of current state is stored, the data of the battery bag of storage include the residue electricity of battery
Measure the parameter such as (SOC) and/or cell health state (SOH), the data can be obtained by battery management unit and store to
In EEPROM, in order to permanently storing for data, and after a power failure, battery management unit or other units still can be to these
Data carry out extraction and further application.
After information stores successfully, step S43 can be traveled further into, the data message of storage is further prompted, such as
Client terminal or other control units are reported, for the further display of information, then, continue step S07, are carried out
Under it is electrically operated, i.e., after wake-up signal is arranged to invalid, carry out it is electrically operated under corresponding low-pressure control module, it is common, whole
After the wake-up signal of vehicle controller is arranged to invalid, vehicle control unit controls battery management system and/or electric machine controller etc.
Terminate to power in related low-voltage power supply part.
So far, lower electric control operation is completed.
In step S04, if the output current of the charger obtained is not zero, then it is assumed that charger output has event
Barrier, step S41 is carried out, store the defeated out of order status information of charger current, can be by output current of charger fault bit mark
Note is masked as failure, and determines whether the fault message can be repaired, and such as by the clear wrong operation of transmission system or restarts
After operation, failure vanishes, then it is assumed that fault message can be repaired, if can not repair, failure is stored, traveled further into
Step S43, the data message of storage is further subjected to fault cues, after such as reporting client terminal or other control units,
For the further prompting of fault message, such as prompted by display terminal or sound or language, so as under ensure that entirely
The integrality and accuracy of data during electric control, improve the reliability and security of whole system.
