Line mode, repair and parts exchange to electric car bring very big difficulty, while also result in the wasting of resources and security risk.
2. whole electric vehicle and its electric accessory motor are stolen, situation is serious, and it is after stolen accessory is easily renovated to trace it to its cause
Again sell and obtain sudden huge profits.
The content of the invention
Present applicant proposes the automatically controlled schemes of low cost, can be solved the above problems, are related to system:
Electric car three-wire system carrier wave 1. (B-TRI Bus) bus control system, electric car two-wire system carrier wave bus (B-PLC
Bus) control system;
2. instrument disk controller and its SOC chip (model MD80F9234) with safe encryption function
3. the battery controller with safe encryption function and its SOC chip (model MD80F9222)
4. electric machine speed regulation controller and its SOC chip (model MD80F9211) with safe encryption function
5. electric accessory motor identifies encryption system and traceability management system
The electric car assembled with this programme, electric machine speed regulation controller, the on line between instrument board, battery can be reduced to two
Root power cord (i.e. two-wire bus system) B-PLC Bus or two add one with signal wire (three-wire bus system) B-TRI with power cord
Bus has been greatly saved connecting line quantity, simplifies maintenance program, while the generation that electric accessory motor is promoted to seek unity of standard.
Meanwhile the electric accessory motor produced using this programme, the core of each accessory have one there is safety to add
The chip of close function, chip internal have independent ID number, this ID number, by producer's burning, is only provided when dispatching from the factory by producer
Special equipment could change.When dispatching from the factory, each accessory of an electric car is belonged to, possesses identical id number, such as
Vehicle Identify Number is the instrument disk controller of 9527 electric car, electric machine speed regulation controller, the ID number of the chip inside battery controller
Code is all identical.It cannot be used in the accessory of 9527 vehicle frame difference id numbers above 9527 vehicles.Or second-hand accessory returns
It returns genuine or is handled back to special service station.During the repair of second-hand accessory, the special volume that is provided first by electric car manufacturer
Journey device connects accessory by bus, reads accessory encryption ID and is shown as Quick Response Code, and cell phone application scans the Quick Response Code on programmable device,
And the server of manufacturer is uploaded to, manufacturer personnel after sale know the information of this accessory and sale path first, then exclude to steal and rob object
After product, one group of authorization code of cell phone application is handed down to, it is special that maintenance station or maintenance personal can rely on this authorization code to be provided using manufacturer
The id number of the accessory is changed with programmable device, with vehicle match to be repaired.
Car owner just may be notified that in buying car to be robbed in case of stolen and can the information that vehicle is lost be offered manufacturer, if it find that dimension
The corresponding vehicle of accessory ID number repaiied, which occurs to steal, to be robbed, and manufacturer personnel can notify car owner's relevant information as foundation of reporting a case to the security authorities immediately.
It is internal that this chip is rooted in accessory (such as battery etc.), will if chip removed, it is necessary to depth disassembles accessory
