And S230, after the vehicle is powered down, if the storage battery meets the power-up condition, starting to power up the storage battery, wherein the power-up condition comprises whether the power-down time value of the vehicle exceeds the time interval value.
In an exemplary embodiment of the present application, when the vehicle is powered down and dormant, a real-Time Clock (RTC) chip inside the BMS controller enters a timing mode, and if the accumulated timing exceeds a Time interval value, the RTC automatically sends a wake-up signal to wake up the BMS, so that when the battery completely meets a power-up condition, the battery starts to be charged up.
In an exemplary embodiment of the application, after the vehicle is powered down, if the storage battery meets the power-up condition, the method for starting to supplement the power to the storage battery comprises the steps of determining whether the voltage value of the storage battery of the vehicle is smaller than a storage battery voltage threshold value and determining whether the residual power value of the power battery of the vehicle is larger than or equal to the residual power threshold value based on the state information of the current vehicle if the power-down time value of the vehicle exceeds a time interval value after the vehicle is powered down, and starting to supplement the power to the storage battery if the residual power value of the power battery is larger than or equal to the residual power threshold value.
For example, when the vehicle is powered down and dormant, the RTC in the BMS controller enters a timing mode, if the accumulated timing exceeds a time interval value, the RTC automatically sends a wake-up signal to wake up the BMS, when the BMS detects that the BMS is self-awakened by the RTC, the BMS is initialized, if the duration is longer than 5 seconds, the current voltage value of the storage battery is detected to be smaller than a voltage threshold value (for example, smaller than 12V) of the storage battery, the residual electric quantity value of the power battery is larger than or equal to the residual electric quantity threshold value (for example, 5%), the power battery system does not inhibit the high-voltage fault, and after the intelligent low-voltage power supply is allowed by the power battery, the storage battery is started to be supplied with power.
In an exemplary embodiment of the application, if the storage battery meets the power-up condition, the method for starting to supplement power to the storage battery comprises the steps of controlling a battery management system to enter a sleep mode and waking up a corresponding controller through a network management message, wherein the controller comprises a whole vehicle controller (VCU, vehicle control unit), a direct current-direct current converter (DC-DC converter) and a vehicle networking system (T-BOX, TELEMATICS BOX), initializing the controller, and if the initialization of the controller fails, controlling a vehicle to enter the sleep mode.
For example, when the BMS wakes up the entire vehicle controller, the dc-dc converter, the internet of vehicles system, and other controllers through the network management message. If any one of the battery power supply conditions is not satisfied, the BMS judges that the battery power supply conditions are not satisfied, and the BMS directly jumps to the sleep flow. And if the controller is awakened, the direct current-direct current converter feeds back the standby working state after the initialization to the whole vehicle controller, and when the whole vehicle controller receives the standby working state of each controller, the whole vehicle controller sends an upper high voltage permission instruction to the BMS.
In an exemplary embodiment of the application, the method for supplementing the power of the storage battery of the vehicle further comprises the steps of controlling the battery management system to supplement the power of the storage battery if the controller is initialized successfully, and controlling the battery management system to enter a sleep mode if a fault condition is reached when the power of the storage battery is supplemented, wherein the fault condition comprises at least one of a high-voltage fault of the vehicle, a power-up time exceeding a preset power-up time value or a residual power value of a power battery of the vehicle being smaller than a preset residual power value of the power battery.
For example, after the BMS receives the high voltage allowing instruction sent by the vehicle controller, the BMS executes the high voltage allowing process, firstly controls the negative contactor to be attracted, secondly controls the pre-charging contactor to be attracted, and finally controls the main positive contactor to be attracted, and when all the contactors are attracted, the pre-charging contactor is disconnected, and the high voltage is completed at this time. If the high-voltage fault exists in the high-voltage power-on process of the whole vehicle or the power-on exceeds a preset power-on time value (for example, 5 seconds), the battery management system is directly controlled to enter a sleep mode, or when the direct current-direct current converter receives a BMS high-voltage power-on completion signal, the direct current-direct current converter converts the high-voltage power battery into 14.5V high-voltage power to charge a low-voltage 12V storage battery, at the moment, the BMS starts timing for 30 minutes, and after the time arrives, the BMS sends an instruction for prohibiting intelligent 12V power-on. If the BMS detects that the power battery residual electricity value is smaller than the power battery preset residual electricity value in the electricity supplementing process, the BMS directly jumps to the BMS to execute the power-down dormancy process.
In an exemplary embodiment of the application, the method for supplementing the power of the vehicle storage battery further comprises the steps of obtaining the current electric quantity information of the storage battery after the power supplementing of the storage battery is completed, and sending the electric quantity information of the storage battery to a corresponding terminal, wherein the terminal comprises at least one of a vehicle-mounted terminal and mobile electronic equipment.
For example, after the vehicle controller receives the instruction of prohibiting intelligent 12V power up from the BMS, the vehicle controller sends the instruction of permitting high voltage down to the BMS. The BMS executes a low-voltage process, firstly controls the main positive contactor to be disconnected, secondly controls the main negative contactor to be disconnected, the BMS sends a signal after the high-voltage power reduction is completed to the T-BOX, the T-BOX sends electric quantity information of the low-voltage 12V storage battery after power compensation to a corresponding terminal (for example, a mobile phone and displays the electric quantity information of the storage battery in the mobile phone APP), and a user can visually confirm whether the low-voltage 12V storage battery of the vehicle is deficient or not.
In an exemplary embodiment of the present application, after each controller of the whole vehicle enters a low-voltage standby working state, when the BMS detects that the RTC wake-up signal is invalid, the BMS executes to stop sending the network management message and then enters dormancy. And enabling controllers such as VCU, DCDC, T-BOX to enter sleep after detecting that the sleep condition of the intelligent 12V power-supplementing mode is met, and entering the next intelligent power-supplementing cycle.
In summary, the method for recharging a vehicle storage battery of the present application determines a time interval value for recharging the storage battery according to the state information of the current vehicle before powering down (the state information includes one or more of a high-voltage power-on time length value of the vehicle, an environment temperature value of the vehicle, a power battery residual electric quantity value of the vehicle and a storage battery voltage value of the vehicle), and after powering down the vehicle, if the storage battery meets a recharging condition (the recharging condition includes whether the power-down time value of the vehicle exceeds the time interval value), the recharging of the storage battery is started. Therefore, the method for supplementing electricity to the vehicle storage battery can intelligently adjust the time interval value of the battery for supplementing electricity, further effectively improve the service life attenuation problem of the storage battery, avoid the problems that the storage battery cannot timely supplement electricity and the electricity consumption of the battery is excessive due to frequent power supplementing, and meanwhile, the vehicle is not started for a long time, and a user can know the voltage of the low-voltage 12V storage battery of the vehicle and whether the vehicle is deficient or not through the mobile phone APP after the intelligent battery supplementing is finished.
