（1）Vehicular charger can only be according to particular design output rated voltage, and this results in Vehicular charger and can only used In specific voltage platform；
（2）Existing Vehicular charger can not collect the status information of various parts in charging system, can not realize charging The automatic start-stop of machine and the defencive function to battery；
（3）Existing Vehicular charger can not detect the connection status of charging equipment and Vehicular charger, be handed over when needing to extract During current charge rifle, it can not voluntarily stop charging in time, probably due to plugging and causing the damage of personnel and equipment；
（4）Existing Vehicular charger can not realize that charging terminates isolating for rear battery high pressure and Vehicular charger.
The content of the invention
It is an object of the invention to overcome drawbacks described above, there is provided a kind of intelligence degree for electric-vehicle-mounted charger Height, realize convenient intelligent charge control method.
To achieve these goals, the present invention uses following technical scheme：
A kind of intelligent charge control method based on electric car, it is embedded on charger that there are three railway digital amount output channels The multi-functional embedded controller of digital quantity input channel all the way, charger are robbed by the detection charging of digital quantity input channel Connection status；Charger configures output voltage by digital output passage；Charger is realized logical with BMS by CAN module Letter.
Specifically, the control method comprises the following steps：
Charging connection
（1）When the charging gun of charging equipment is inserted into charger input interface, if digital quantity input channel has low level Signal inputs, then it is assumed that charging gun has connected, conversely, not connected；
Charging prepares
（2）After charging gun connection, postpone the N seconds, the AC relay and electrokinetic cell that the output end of charger passes through closure Connection, wherein, N is more than 1；
（3）Postpone the M seconds, charger is communicated by CAN module with BMS, and the maximum that BMS sends electrokinetic cell to charger is filled Electric current and charging voltage, wherein, M is more than 1；
（4）Charger sets output parameter according to the maximum charging current and charging voltage of reception；
In charging
（5）Charger detects whether the battery status of BMS transmissions and digital quantity input channel have low level input in real time；
Stop charging
（6）If BMS sends battery status abnormal information, stop charging, if situation without exception, until charging current is small In setting value, then stop charging；If detecting, digital quantity input channel inputs without low level, stops charging.
In charging process, if the operating temperature of charger is more than setting value, starts radiator fan and charger is carried out Cooling.
Compared with prior art, the beneficial effects of the present invention are：
(1) using the present invention can Intelligent adjustment Vehicular charger output parameter, expand the scope of application；
(2) start and stop of the achievable intelligentized control method Vehicular charger of the present invention, the convenience of charging and reliable is improved Property；
(3) using the present invention, after AC charging rifle is extracted, high_voltage isolation is realized, improves the security of charging this hair It is bright.
