System, Communication diagnostic box, PC and mobile terminal；The battery management system is used to be managed the battery of electric automobile；
The Communication diagnostic box be a network transmission system, its networks matches with the battery management system；The PC with
And the mobile terminal has respectively the upgrade file upgraded for the battery management system；The Communication diagnostic box passes through
Multichannel CAN is connected with the battery management system；When being upgraded for the battery management system, the PC or
Upgrade file in the mobile terminal be divided into it is multiple send to the Communication diagnostic box, the Communication diagnostic box will be the plurality of
File is transmitted to the battery management system respectively by the multichannel CAN concurrent type frog.
Further, the battery management system include main frame, the main frame it is same realize Multi net voting while receiving institute
Upgrade file is stated, and can be according to the speed of the corresponding regulation and control transmission of the load of every road CAN.
Further, the Communication diagnostic box transmits the plurality of file to the electricity by five tunnel CANs respectively
Pond management system.
Further, the Communication diagnostic box is communicated by Ethernet with the PC.
Further, the Communication diagnostic box is wirelessly communicated with the mobile terminal.
Further, the mobile terminal is also wirelessly communicated with the PC；When the cell tube
During reason system malfunctions, the main frame sends fault message to the Communication diagnostic box, institute by the multichannel CAN
State Communication diagnostic box wirelessly the fault message to be sent to the mobile terminal, then the mobile terminal is logical
Cross and wirelessly the fault message is sent to the PC.
The communication system of use multichannel CAN provided by the present invention, due to the Communication diagnostic box and the battery management
Carried out data transmission using multichannel CAN between system, and then the updating speed of the battery management system is got a promotion,
The stability of upgrading is also improved while improve liter stage efficiency.
【Description of the drawings】
Fig. 1 is the module map of the communication system of use multichannel CAN provided in the embodiment of the present invention.
【Specific embodiment】
In order that the purpose of the present invention, technical scheme and Advantageous Effects become apparent from understanding, below in conjunction with accompanying drawing and
Specific embodiment, the present invention will be described in further detail.It should be appreciated that being embodied as described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
It is the module map of the communication system of use multichannel CAN provided in the embodiment of the present invention referring again to Fig. 1.It is described
Include battery management system 10, Communication diagnostic box 20, PC (Personal Computer) using the communication system 100 of multichannel CAN
Machine 30 and mobile terminal 40.The battery management system 10 is used to be managed the battery of electric automobile, its major function
Including：Battery physical parameter real-time monitoring, battery status estimation, inline diagnosis and the control of early warning, discharge and recharge and preliminary filling, equalizer line
Reason and heat management etc..Further, the battery management system 10 includes main frame 11, and the main frame 11 is used to receive upgrading journey
Preface part to the battery management system 10 upgrading.
The Communication diagnostic box 20 be a network transmission system, its network phase with the battery management system 10
Match somebody with somebody.Specifically, the Communication diagnostic box 20 is connected by multichannel CAN with the battery management system 10.In this embodiment party
In formula, the Communication diagnostic box 20 is communicated by five tunnel CANs with the battery management system 10.
Further, the Communication diagnostic box 20 is also communicated with the PC 30 and the mobile terminal respectively.
In the present embodiment, the Communication diagnostic box 20 is communicated by Ethernet with the PC 30.The Communication diagnostic box
20 are also wirelessly communicated with the mobile terminal 40.The PC 30 and the mobile terminal 40 have for
The upgrade file that the battery management system 10 is upgraded.
When being upgraded for the battery management system 10, in PC 30 described first or the mobile terminal 40
Upgrade file is divided into multiple, then sends by Ethernet or wirelessly to the Communication diagnostic box 20, the communication
Diagnosis box 20 by the plurality of file respectively by the multichannel CAN carry out concurrent type frog transmit with increase transmission speed and
Throughput, so that updating speed is guaranteed.Further, what the end of the main frame 11 was same realizes Multi net voting while connecing
The upgrade file is received, and then causes every CAN to play effect when upgrading, and can be total according to every CAN
The speed of the corresponding regulation and control transmission of load of line.In present embodiment, because the multichannel CAN is five tunnel CANs, because
This, can be divided into five parts by the upgrade file.It is appreciated that having identical in the mobile terminal 40 and the PC 30
Upgrade file, can select to be upgraded with the mobile terminal 40 or the PC 30 according to real needs.
Additionally, the mobile terminal 40 can also be communicated wirelessly with the PC 30.When the electricity
When pond management system 10 breaks down, the main frame 11 sends fault message to the Communication diagnostic by multichannel CAN
Box 20, the Communication diagnostic box 20 wirelessly sends the fault message to the mobile terminal 40, then institute
State mobile terminal 40 wirelessly the fault message to be sent to the PC 30, therefore, the attendant without
