Entire car controllers of the CC_OUT for waking up vehicle, the status information for the CAN collection vehicle that entire car controller passes through vehicle,
Comprehensive various information and CC_OUT signals judge whether current vehicle-state can charge or drive a vehicle, and realize driving and charging
Interlocking, is started to charge up after preventing vehicle launch, or vehicle launch in charging process, and car status information is transmitted to vehicle-mounted and filled
The control device of motor, Vehicular charger perform charging according to vehicle-state and control command.
In some embodiments of the invention, if discharge and recharge muzzle connection be charging gun when, Vehicular charger is adopted
Collect CP signals, and power network alternating current is converted to by direct current according to the control command of entire car controller and thinks that power battery pack is carried out
Charging；If the external loading of discharge and recharge muzzle connection, entire car controller order is accepted by power battery pack in Vehicular charger
Direct current be converted to alternating current and be powered for external loading；If the connection of discharge and recharge muzzle is outside Vehicular charger,
It is i.e. vehicle-to-vehicle to be powered, then Vehicular charger simulation output CP signals, i.e., similar to mobile charging stake, and by power battery pack
Direct current be converted to alternating current and supply another vehicle, realize vehicle-to-vehicle power supply control.Meanwhile the battery management system of vehicle
The charging and discharging state of electrokinetic cell can be monitored by gathering hard signal, and be sent out charged state by the CAN of vehicle
Give entire car controller.
Furthermore, it is understood that in some embodiments of the invention, under outside Vehicular charger powering mode, according to connection
Confirmation signal controls the output power stage of Vehicular charger.Specifically, Vehicular charger can mould similar to a mobile charging stake
CP signals are sent out out, realize vehicle-to-vehicle charge function, the vehicle for being equipped with the Vehicular charger can be according in charging pipette tips
The different electric discharges that different capacity level is carried out to charging vehicle of CC signals such as detection resistance value, supplement energy for it, avoid filling
Electric car on the way casts anchor because of battery electric quantity deficiency.
In some embodiments of the invention, in Vehicular charger discharge and recharge, the status information of Vehicular charger is obtained
To be prompted, for example, the failure of Vehicular charger and status information are reported into vehicular meter to carry out by CAN
Prompting, the charge status of Vehicular charger can be understood at any time.
