Embodiments of the present application describe a method and system for recharging a battery of a vehicle and a computer readable medium.
Fig. 1 is a schematic diagram of a charge replenishing method for a battery of a vehicle according to an embodiment of the present application.
As shown in fig. 1, the method for replenishing the charge of the battery of the vehicle comprises a step 101 of monitoring the voltage of the battery and the state information of the vehicle at a first cycle by a battery management system and including them in a first data set; step 102, acquiring state information of the vehicle from a cloud server end through a vehicle-mounted T-BOX in a second period, detecting a voltage value of the storage battery at a vehicle control unit, and including the voltage value in a second data group; 103, when the vehicle control unit judges that the first data set can be acquired, judging whether the storage battery needs to be supplemented with electric quantity according to the first data set; and step 104, when the vehicle control unit judges that the first data set can not be acquired, judging whether the storage battery needs to be supplemented with electric quantity according to the second data set.
Specifically, in step 101, the voltage of the Battery and the state information of the vehicle are monitored at a first cycle by a Battery Management System (BMS) and included in a first data set. The battery includes a lead-acid battery on a vehicle, such as a new energy automobile or an electric automobile. The storage battery obtains the supplement of electric quantity from a power battery of the vehicle, such as a lithium battery. The power battery of the vehicle can be charged through the charging pile, and the power battery can be replaced. The power supply voltage of the power battery is high, and may be, for example, hundreds of volts (V).
The accumulator can then supply the control system or the network communication system of the vehicle, and the supply voltage of the accumulator is relatively low compared with the power battery, for example 10-20 volts, or set according to the actual situation.
In step 102, state information of the vehicle is acquired from a cloud server side through an on-board T-BOX at a second period, and a voltage value of the storage battery is detected at a vehicle control unit and included in a second data set.
The vehicle-mounted T-BOX (telematics BOX) refers to a vehicle networking system or a vehicle-mounted intelligent interconnection terminal. The vehicle-mounted T-BOX can be connected with the cloud server end through a network.
In some embodiments, the status information of the vehicle includes whether the vehicle is in a running state. The second period may be greater than the first period. The state information of the vehicle monitored by the battery management system may be acquired by a Body Control Module (BCM). The first period is, for example, tens of seconds, or minutes, or hours. The second period may be a natural day (one day) and a time interval of two natural days (two days).
In step 103, when the Vehicle Control Unit (VCU) determines that the first data set can be acquired, it is determined whether the battery needs to be replenished with electric energy based on the first data set. In one embodiment, according to information included in the first data, when the vehicle is in a non-running state and the voltage of the storage battery is smaller than a set threshold value, the vehicle control unit sends an enable signal to start a charging operation of the storage battery by the direct current converter. The DC converter charges the storage battery with the electric energy of the power battery. The set threshold values are, for example, 10V, 10.5V, 11V, 11.5V, … ….
In step 104, when the vehicle control unit determines that the first data set cannot be acquired, it is determined whether the battery needs to be replenished with electric energy based on the second data set. In one embodiment, according to information included in the second data, when the vehicle is in a non-running state and the voltage of the battery is less than a set threshold, the vehicle control unit sends an enable signal to start a charging operation of the battery by the dc converter.
In some embodiments, the method for replenishing the battery of the vehicle of the present application further includes a power supply discharge operation, and the power supply exit operation includes: and when the voltage of the storage battery acquired by the vehicle control unit from the battery management system is greater than a second threshold value or the state information of the vehicle meets a set condition, sending an enabling signal and quitting the charging operation. The issued enable signal for example turns off the dc converter. The second threshold is, for example, 12V, 12.1V, 12.2V, …, 12.5V, …, or the like.
In one embodiment, the state information of the vehicle satisfies the set condition, for example, including that the vehicle is in a running state.
When the vehicle is in the running state, the storage battery is always powered by the power battery to meet the electric quantity requirement of the storage battery, and whether power supplementing operation is needed or not or quit the power supplementing operation is not needed to be judged through the control logic.
When the vehicle is in a non-running state, the storage battery can be in a slow feeding state (namely, the electric quantity contained in the storage battery is slowly reduced due to the inherent characteristic of the storage battery), and when the electric quantity of the storage battery is reduced to be below a specific value, the working voltage which can be provided by the storage battery can possibly fail to meet the requirements of starting and running of the vehicle, namely the requirements of supplying power to a control system and a network communication system of the vehicle, and can cause the vehicle to fail to start normally or to operate normally. When the running state of the vehicle changes or the voltage of the storage battery is larger than a second threshold value, an enabling signal is sent out through the vehicle control unit, and the charging operation is quitted.
Therefore, the electric quantity supplementing method of the storage battery of the vehicle can maintain the voltage of the storage battery of the vehicle at a level which can meet the starting and running conditions of the vehicle, and therefore the storage battery of the vehicle is ensured to be in a normal use state.
The present application also provides a charge replenishment system for a battery of a vehicle, the system including a Battery Management System (BMS), an on-board T-BOX, a direct current converter (DC-DC converter), and a Vehicle Control Unit (VCU).
As described above, fig. 2 is a schematic composition diagram of a charge amount supplement system for a battery of a vehicle according to an embodiment of the present application.
In some embodiments, the battery management system is configured to: the voltage of the battery (e.g., arrow (c) in fig. 2) and the state information of the vehicle are monitored at a first cycle and included in a first data group. The onboard T-BOX is configured to: the status information of the vehicle is obtained from the cloud server side at the second period (e.g., obtained from the cloud server side by arrow r in fig. 2 and transferred to vehicle control unit VCU by arrow (c)) and included in the second data set. The vehicle control unit is configured to: the voltage value of the battery is detected (for example, by the flow of signals indicated by the arrow in fig. 2) and included in the second data set. The first data set and the second data set may be stored, for example, in a Vehicle Control Unit (VCU).
The vehicle control unit is further configured to perform the following operations: when the vehicle control unit judges that the first data set can be acquired (for example, when signal flow shown by an arrow (r) and/or an arrow (r) in fig. 2 can be normally transmitted), judging whether the storage battery needs to be supplemented with electric quantity according to the first data set; and when the vehicle control unit judges that the first data set cannot be acquired, judging whether the storage battery needs to be supplemented with electric quantity according to the second data set.
In some embodiments, the second period is greater than the first period. The state information of the vehicle includes whether the vehicle is in a running state. The state information of the vehicle monitored by the battery management system may be obtained by a Body Control Module (BCM) (e.g., a signal flow shown by an arrow (r) in fig. 2).
The battery includes a lead-acid battery on a vehicle, such as a new energy automobile or an electric automobile. The storage battery obtains the supplement of electric quantity from a power battery of the vehicle, such as a lithium battery. The power battery of the vehicle can be charged through the charging pile, and the power battery can be replaced. The power supply voltage of the power battery is high, and may be, for example, hundreds of volts (V). The accumulator can then supply the control system or the network communication system of the vehicle, and the supply voltage of the accumulator is relatively low compared with the power battery, for example 10-20 volts, or set according to the actual situation.
In an embodiment, according to the information included in the first data, when the vehicle is in a non-running state and the voltage of the battery is smaller than a set threshold, the vehicle control unit sends an enable signal (for example, through a signal stream indicated by an arrow (c) in fig. 2) to start the dc converter to perform a charging operation on the battery (for example, through a signal stream indicated by an arrow (c) in fig. 2).
In some embodiments, the method for replenishing the battery of the vehicle of the present application further includes a charge exiting operation, and the charge exiting operation includes: when the voltage of the storage battery acquired by the vehicle control unit from the battery management system is greater than a second threshold value or the state information of the vehicle satisfies a set condition, an enable signal is issued to exit the charging operation (for example, by a signal flow shown by a signal ninu and a signal (r) shown in fig. 2).
The above-described relationship between the operation process of the system and the signal flow is only a schematic representation for the convenience of understanding the scheme of the present application, and is not intended to limit the present invention. The actual signal flow per arrow does not have to strictly correspond to the above procedure, and may be adjusted according to the actual system configuration.
The electric quantity supplementing system of the storage battery of the vehicle can maintain the voltage of the storage battery of the vehicle at a level which can enable the storage battery to meet starting and running conditions of the vehicle, and therefore the storage battery of the vehicle is guaranteed to be in a normal use state.
