(1) Vehicular charger can only according to particular design output rated voltage, and this just causes Vehicular charger can only be used in specific voltage platform;
(2) existing Vehicular charger cannot collect the state information of various parts in charging system, cannot realize the automatic start-stop of charger and the defencive function to battery;
(3) existing Vehicular charger cannot detect the connection status of charging device and Vehicular charger, when AC charging rifle extracted by needs, cannot stop charging in time voluntarily, may cause the damage of personnel and equipment because of warm swap;
(4) existing Vehicular charger cannot realize charging and terminate the isolation of rear battery high pressure and Vehicular charger.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide a kind of intelligence degree for electric-vehicle-mounted charger high, realize intelligent charge control method easily.
To achieve these goals, the present invention is by the following technical solutions:
Based on an intelligent charge control method for electric motor car, charger embeds the multi-functional embedded controller with three railway digital amount output channels and a railway digital amount input channel, charger detects the connection status of charging and robbing by digital quantity input channel; Charger is by digital output passage configuration output voltage; Charger realizes the communication with BMS by CAN module.
Specifically, this control method comprises the following steps:
Charging connects
(1) when the charging gun of charging device is inserted into charger input interface, if digital quantity input channel has low level signal to input, then think that charging gun connects, otherwise, do not connect;
Charging prepares
(2) after charging gun connects, postpone N second, the output of charger is connected with electrokinetic cell by closed AC relay, and wherein, N is greater than 1;
(3) postpone M second, charger is communicated with BMS by CAN module, and BMS sends maximum charging current and the charging voltage of electrokinetic cell to charger, and wherein, M is greater than 1;
(4) charger arranges output parameter according to the maximum charging current received and charging voltage;
In charging
(5) charger detect in real time BMS send battery status and digital quantity input channel whether have low level to input;
Stop charging
(6) if BMS sends battery status abnormal information, then stop charging, if situation without exception, then until charging current is less than set point, then stop charging; If detect, digital quantity input channel inputs without low level, then stop charging.
In charging process, if the working temperature of charger is greater than set point, then starts radiator fan and charger is lowered the temperature.
Compared with prior art, beneficial effect of the present invention is:
(1) adopt the present invention can the output parameter of Intelligent adjustment Vehicular charger, expand the scope of application;
(2) the present invention can realize the start and stop of intelligentized control method Vehicular charger, improves convenience and the reliability of charging;
(3) adopt the present invention, after extracting AC charging rifle, realize high_voltage isolation, improve fail safe the present invention of charging.
