Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here to implement, therefore the present invention is not by the restriction of following public specific embodiment.
In the present invention, propose electric control method under a kind of charger, be lower electric control in power brick charging process for electric motor car by onboard charger or quick charger, comprise: the state information obtaining charging gun; When charging gun state information is not for extracting, obtain power brick charging status information; When power brick electricity condition information is for being full of electricity, obtain the output current of charger; When the output current of charger is zero, cut off charging wake-up signal; Storage battery bag charging status information.
In the present invention, by the output current of the state information of charging gun, power brick charging status information and charger, judge the operating state of charging gun step by step, and record power brick charging status information, improve the effective management to charging gun power-down state, the information dropout avoiding unexpected lower electricity to cause, improves the accuracy of battery management system strategy, and then improves reliability and the fail safe of whole battery system.
Technical scheme for a better understanding of the present invention and technique effect, be described in detail below with reference to specific embodiment and schematic flow sheet.
As shown in Figure 1, first, in step S01, charge mode is entered.
When charging gun enters charge mode, charging gun is connected in mains-supplied network, now, charger sends charging wake-up signal, this charging wake-up signal is level signal, is usually sent to entire car controller unit, after entire car controller unit receives this charging wake-up signal, namely think that power brick enters charge mode, charging gun is connected to power inlet.
Then, in step S02, obtain the state information of charging gun.
By obtaining charging wake-up signal, can obtain the state information of charging gun, when the wake-up signal that charges is effective, the state information of charging gun is not for extract, and when the wake-up signal that charges is invalid, then the state information of charging gun is for extract.
When the state information of charging gun is not for extracting, then continues to obtain power brick charging status information, enter step S03.
When the state information of charging gun is for extracting, then enter step S06, carry out the storage of power brick data, now, the data of power brick stored comprise the parameters such as the dump energy (SOC) of battery and/or cell health state (SOH), these data can be obtained by battery management unit and be stored in EEPROM, so that the permanent storage of data, and after a power failure, battery management unit or other unit still can carry out extraction and further application to these data.
Then, in step S03, obtain power brick charging status information.
The charging status information of power brick can be obtained by battery management unit, whether the charging status information of power brick and power brick are full of electricity, in charging process, battery management unit continues the voltage of the battery cell obtained in power brick, if the voltage of battery unit cell reaches threshold voltage, then think that power brick is full of electricity, otherwise, think that power brick underfill is electric.The charging status information of this power brick can send entire car controller or other processor unit by battery management unit to by the mode of CAN communication.
In this step, continue to obtain power brick charging status information, until the charging status information of power brick is power brick be full of electricity.
Then, in step S04, the output current of charger is obtained.
After the power brick got has been full of the information of electricity, continue the output current obtaining charger, when adopting onboard charger to charge, obtaining the output current of onboard charger, when adopting quick charger to charge, obtaining the output current of quick charger, when the output current of charger is zero, then can think that power brick has been full of electricity and the state of charger is normal, in this case, safe lower electric control operation can be carried out.Common, battery management unit can obtain the output current of this charger, can export battery management unit to obtain by current sensor, battery management unit sends this current information to entire car controller or other processor unit by the mode of CAN communication.
Then, in step S05, cut off charging wake-up signal.
When the output current of charger is zero, cut off charging wake-up signal, it is invalid that the charging wake-up signal by charger is set to.
Then, in step S06, storage battery bag charging status information.
Now, store the power brick data message of current state, the data of power brick stored comprise the parameters such as the dump energy (SOC) of battery and/or cell health state (SOH), these data can be obtained by battery management unit and be stored in EEPROM, so that the permanent storage of data, and after a power failure, battery management unit or other unit still can carry out extraction and further application to these data.
Store successfully in information, step S43 can be entered further, the data message of storage is pointed out further, as reported client terminal or other control units, for the further display of information, then, proceed step S07, carry out lower electricity operation, namely wake-up signal be set to invalid after, carry out electricity operation under corresponding low-pressure control module, common, the wake-up signal of entire car controller be set to invalid after, the relevant low-voltage power supply parts such as vehicle control unit controls battery management system and/or electric machine controller terminate power supply.
So far, lower electric control operation is completed.
In step S04, if when the output current of the charger obtained is non-vanishing, then think that charger output exists fault, carry out step S41, store the defeated out of order state information of charger current, output current of charger fault position can be masked as fault, and judge whether this fault message can be repaired further, after passing through the clear wrong operation of transmitting system or reboot operation, failure vanishes, then think that fault message can be repaired, if can not repair, then fault is stored, enter step S43 further, the data message of storage is carried out fault cues further, after reporting client terminal or other control units, for the further prompting of fault message, as pointed out by display terminal or sound or language, thus, ensure that integrality and the accuracy of data in whole lower electric control process, improve reliability and the fail safe of whole system.
Be described in detail the lower electric control method of the embodiment of the present invention above, present invention also offers the lower controller for electric consumption corresponding with said method in addition, shown in figure 2, described charger is onboard charger or quick charger, comprising:
Charging gun state information acquisition unit 100, for obtaining the state information of charging gun;
