Description
Technical field
The present invention relates to field of electronics more particularly to the electrification control methods and device of a kind of battery management system.
Background technique
New-energy automobile is the important development direction of current automobile industry, and having quite a few in new-energy automobile is to rely on
Electrically driven (operated), therefore, battery management system is the big core component on new-energy automobile, in different electric frameworks
In, the system development of battery management system has been related to the controllability of the system work of vehicle, so, battery management system institute
The function control that can be realized just seems important.
Existing electric car power-on and power-off control strategy is to pass through acquisition under the premise of existing vehicle power system architecture
Driver actions' signal such as key and pedal, and pass through the subsystems such as CAN bus, BMS (battery management system) and electric machine controller
System is communicated, and is powered on controlling vehicle high pressure, lower electricity safety.Simultaneously in upward and downward electric process, it is diagnosed to be vehicle dynamical system
High voltage fault and make respective handling rapidly.
In the prior art, vehicle powers on after VCU (entire car controller) obtains wake-up signal, passes through VCU (full-vehicle control
Device) BMS (battery management system) is waken up, after confirming BMS (battery management system) fault-free, send the instruction of high pressure preliminary filling, BMS
(battery management system) executes high pressure preliminary filling.In the control strategy of the prior art, mainly by VCU (entire car controller) to BMS
(battery management system) is controlled.Since VCU (entire car controller) needs to coordinate the movement of vehicle, and BMS (battery management system
System) it is then under relatively attached control function, therefore, in upper electric control, BMS (battery management system) is whole to be needed
The participation of VCU (entire car controller) will often occupy VCU (entire car controller), so that the processing of VCU (entire car controller) is negative
Load aggravates.The problems such as will ultimately result in the delay powered on.
Summary of the invention
The technical problem to be solved by the present invention is to BMS the problem of more control function of VCU is occupied when powering on.In order to
Solve the above problems, the invention proposes a kind of electrification control method of battery management system and device, the present invention be specifically with
What following technical solution was realized：
The first aspect of the invention proposes a kind of electrification control method of battery management system, the method includes：
Detect whether key signal IG1 is effective, and whether real-time clock waking-up is effective, if receive network message wake-up；
It reads internal non-volatile and stores historical failure, initialize, and judge whether to initialize successfully；
It reports and wakes up reason and state to vehicle network；
Judge whether there is failure；
Judge whether vehicle wake source stops working；
It obtains the high pressure that control module issues and powers on preliminary filling instruction, and execute the operation of high pressure preliminary filling, judge that high pressure preliminary filling is
It is no to complete at the appointed time；
High-voltage relay state is reported to vehicle network；
Execute electrion.
Further, key signal IG1 is effective, real-time clock waking-up is effectively and after network message wakes up effectively obtaining,
It initializes.The interface of the execution module is connected with key signal, when key signal IG1 is effective, executes mould
Block, which obtains clock wake-up and network message, execution module, can start to be initialized.
Further, when judgement is there are when failure, the grade of reporting fault juxtaposition failure.
Further, the grade of failure is judged, when fault level is low, continues power on operation, work as fault level
Gao Shi stops power on operation.
Further, the failure includes insulation fault, high-voltage interlocking failure, total voltage is abnormal, monomer voltage is abnormal and
Current signal is abnormal.
Further, when high pressure preliminary filling is not completed at the appointed time, high pressure is reported to power on time out fault.
Further, when initializing failure, initialization failure flags position is set, is carried out down electrically operated.When initialization fails
When, execution module cannot with vehicle carry out CAN communication, set initialization failure flags position, if can establish at this time communication if on
Reporting an error, it is electrically operated to miss and execute down, can not carry out in next step, user being needed to re-start power on operation if it cannot communicate.
In above-mentioned power up, when PEPS (keyless entry and activation system) or firing key send enabling signal it
Afterwards, execution module receives IG1 signal, and after obtaining IG1 signal, execution module can start to complete normal low voltage control
Partial power on operation, execution module can carry out preliminary self-test and initialization operation in this process.
After initializing successfully, fault detection module reads various interfaces and detects whether there are failure, depending on the grade of failure
Just, it determines to wipe failure and continue power on operation still to exit power on operation and report an error, if failure is higher ranked,
Stop power on operation and report an error, if the grade of failure is lower, continues power on operation.
When fault detection module determines that monomer voltage detection, total voltage detection, temperature information, insulation resistance detection etc. are all located
In normal state, standby mode can be entered, waits the request command of the closed high relay of control module.
After control module issues the instruction of closed high relay, if execution module cannot at the appointed time will be high
Potential relay closure, execution module send the unsuccessful feedback of preliminary filling to vehicle network.
After high-voltage relay is closed by execution module at the appointed time, the closed message of feedback high-voltage relay
To control module, execution module can enter corresponding electrion state.After the closure for completing high-voltage relay, that is, complete
One control flow, battery management system vehicle power on.
The second aspect of the invention proposes a kind of upper controller for electric consumption of battery management system, which is characterized in that institute
Stating device includes key signal receiving module, clock module, communication module, execution module, control module and fault detection module；
The key signal receiving module wakes up letter for obtaining clock for receiving key signal, the clock module
Number, the communication module is for obtaining network message wake-up；
The execution module is for executing initialization operation and power on operation；
The fault detection module is for detecting failure；
The control module executes the operation of high pressure preliminary filling for controlling execution module.
Further, when the key signal, clock wake-up signal and effective network message wake-up signal, execution module into
Row initialization operation.
Further, the communication module is also used to make execution module and vehicle network communication, and make execution module with
Control module communication.
After execution module initializes successfully, fault detection module carries out fault detection.Insulation fault, height is being not detected
In the case where pressing failure and current failure, control module powers on preliminary filling instruction to execution module transmission, and execution module executes high pressure
Preliminary filling operation.
