The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The invention provides a low-voltage lithium battery static power consumption control system, a low-voltage lithium battery static power consumption control method and a vehicle, and the control system, the method and the vehicle are respectively described below.
Fig. 1 is a schematic structural diagram of an embodiment of a low-voltage lithium battery static power consumption control system according to the present invention, and as shown in fig. 1, a low-voltage lithium battery static power consumption control system 10 includes:
The vehicle multimedia 100 is configured to receive a first control signal sent by the mobile terminal 20;
A hard-wired button 200 for generating a second control signal;
The low-voltage lithium battery management module 300 is configured to receive the first control signal and/or the second control signal, and control on/off of the charge/discharge switch 30 based on the first control signal and/or the second control signal.
The charge-discharge switch 30 is connected between the low-voltage lithium battery and the load of the vehicle, when the charge-discharge switch 30 is turned off, the low-voltage lithium battery stops supplying power to the load, the vehicle has no power consumption, and when the charge-discharge switch 30 is turned on, the low-voltage lithium battery starts supplying power to the load, and the vehicle has power consumption. Thus, by means of the first control signal and the second control signal, control of the static power consumption can be achieved.
It should be noted that: the charge-discharge switch 30 may be a component of the low-voltage lithium battery management module 300, namely: the low-voltage lithium battery management module 300 has the charge/discharge switch 30 integrated therein.
The mobile terminal 20 may be a mobile phone terminal or a tablet terminal.
Compared with the prior art, the low-voltage lithium battery static power consumption control system 10 provided by the embodiment of the invention actively generates the first control signal and the second control signal through the mobile terminal 20 and the hard wire button 200, and realizes the active control of the on-off of the charge-discharge switch 30 based on the first control signal and the second control signal, namely: the active control of the static power consumption is realized, when the electric quantity of the low-voltage lithium battery is smaller than the threshold value after the vehicle is not required to be in a flameout state and the power is down, the charge-discharge switch 30 is disconnected, and a user can actively realize the purpose that the static power consumption of the low-voltage lithium battery is zero under the scene of no vehicle use, so that the energy waste is avoided.
Further, the embodiment of the invention provides two modes of the first control signal and the second control signal to control the on-off of the charge-discharge switch 30, and compared with the prior art, the control mode is more, so that the diversity and redundancy of the static power consumption control mode are improved.
To avoid operational reliability when the low-voltage lithium battery management module 300 receives both the first control signal and the second control signal, in some embodiments of the invention, the second control signal has a higher priority than the first control signal.
In other words: the low-voltage lithium battery management module 300 responds to the second control signal when the first control signal and the second control signal are received simultaneously.
According to the embodiment of the invention, the priority of the second control signal is higher than that of the first control signal, so that an emergency means can be provided, and the charge-discharge switch 30 can be opened or closed in advance.
In order to improve the intelligentization degree of the low-voltage lithium battery static power consumption control system 10, in some embodiments of the present invention, as shown in fig. 1, the low-voltage lithium battery management module 300 includes a timing unit 310 and a control unit 320, where the timing unit 310 is configured to start timing when the low-voltage lithium battery management module 300 receives the first control signal;
The control unit 320 is configured to control the charge-discharge switch 30 to be opened when the time duration is a first time duration, and control the charge-discharge switch 30 to be closed when the time duration is a second time duration.
By arranging the timing unit 310, the embodiment of the invention can automatically control the opening and closing of the charge-discharge switch 30 after receiving the first control signal, and does not need to manually participate in the control of opening and closing the two different switch states, thereby improving the intelligent degree of the low-voltage lithium battery static power consumption control system 10.
The timing unit 310 is specifically a Real-Time Clock (RTC) timer.
The specific working process of the RTC timer is as follows: converting the first time length and the second time length into how many seconds the current time is from the target time, starting timing by the RTC timer, controlling the charge-discharge switch 30 to be opened after the timing reaches the opened target time, and controlling the charge-discharge switch 30 to be closed after the timing reaches the closed target time.
It should be understood that: the first duration and the second duration may be specifically defined according to an actual application scenario.
In one embodiment, the second time period may be set to 8 hours, as the user typically does not use the vehicle at night.
In one particular embodiment, the first time period is zero, i.e.: the control unit 320 immediately controls the charge and discharge switch 30 to be turned off upon receiving the first control signal.
In another specific embodiment, considering the application scenario of temporary parking, the first duration is 1 hour, namely: the control unit 320 controls the charge and discharge switch 30 to be turned off after receiving the first control signal for 1 hour.
Further, by setting the first time length to be 1 hour, time can be provided for storage and parking monitoring of the vehicle, and safety of the vehicle is ensured.
In some embodiments of the present invention, as shown in fig. 1, the vehicle multimedia 100 includes a duration setting unit 110, and the duration setting unit 110 is configured to set a first duration and a second duration.
It should be noted that: the first duration and the second duration may also be set in the mobile terminal 20.
Since the charge/discharge switch 30 cannot be turned off during the driving process of the vehicle, in order to avoid the technical problem that the user sends the first control signal to the low-voltage lithium battery management module 300 of the driving vehicle by mistake, which results in that certain functions of the vehicle cannot be used or even cannot normally run, in some embodiments of the present invention, the vehicle multimedia 100 is further used for receiving a parking stall signal of the vehicle, and the control unit 320 is further used for receiving the parking stall signal and controlling the on/off of the charge/discharge switch 30 based on the parking stall signal and the first control signal.
According to the embodiment of the invention, the on-off of the charge-discharge switch 30 is controlled based on the parking flameout signal and the first control signal, so that the on-off control of the charge-discharge switch 30 is ensured to be carried out after the vehicle flameout, and the safety of the vehicle in running is ensured.
The flameout and parking signal refers to a signal when the vehicle is in a low-high-voltage state and the gear is in a P gear.
In some embodiments of the present invention, the hard-wired button 200 is a self-resetting button, and the second control signal includes a second off control signal for controlling the charge-discharge switch 30 to be turned off and a second on control signal for controlling the charge-discharge switch 30 to be turned on;
When the number of times the hard wire button 200 is pressed is a first preset number of times and the pressing type is a first type, the hard wire button 200 generates a second disconnection control signal;
when the number of times the hard wire button 200 is pressed is a second preset number of times and the pressing type is a second type, the hard wire button 200 generates a second on control signal.
The first preset times, the first type, the second preset times and the second type can be set according to the preference and habit of the user.
In a specific embodiment of the present invention, the first type is a short press, the first preset number of times is 3, the second type is a long press, and the second preset number of times is 1. Namely: when the charge-discharge switch 30 needs to be immediately turned off, the hard-wired button 200 is continuously pressed for 3 times; when it is required to immediately close the charge-discharge switch 30, the 10s hard-wired button 200 is pressed for a long time.
To enable transmission of the first control signal between the mobile terminal 20, the vehicle multimedia 100, and the low voltage lithium battery management module 300, in some embodiments of the present invention, as shown in fig. 1, the mobile terminal 20 includes a target CAN communication unit 21, and the vehicle multimedia 100 includes a wireless communication unit 120 and a first CAN communication unit 130; the low-voltage lithium battery management module 300 includes a second CAN communication unit 330,
The wireless communication unit 120 is configured to receive a first control signal sent by the target CAN communication unit 21 in the mobile terminal 20.
The first CAN communication unit 130 and the second CAN communication unit 330 are connected through a CAN bus, and the first CAN communication unit 130 is configured to receive the first control signal forwarded by the wireless communication unit 120 and send the first control signal to the second CAN communication unit 330.
The vehicle multimedia 100 acts as a signal forwarding intermediary to transfer signals between the mobile terminal 20 and the low voltage lithium battery management module 300.
It should be understood that: the first CAN communication unit 130 is further configured to send the duration setting unit 110 in the vehicle multimedia 100 to the second CAN communication unit 330 for setting the first duration and the second duration.
The invention also provides a method for controlling the static power consumption of the low-voltage lithium battery, which is suitable for the system 10 for controlling the static power consumption of the low-voltage lithium battery in any one of the embodiments, as shown in fig. 2, and comprises the following steps:
s201, receiving a first control signal sent by the mobile terminal 20 based on the vehicle multimedia 100;
s202, generating a second control signal based on the hard wire button 200;
S203, the low-voltage lithium battery management module 300 receives the first control signal and/or the second control signal, and controls the on-off of the charge-discharge switch 30 based on the first control signal and/or the second control signal.
In one embodiment of the invention, the method for controlling the static power consumption of the low-voltage lithium battery comprises the following steps:
The user expects that the vehicle cannot be used in a certain time period, sets the charge-discharge switch 30 to be opened for a first time period and sets the charge-discharge switch 30 to be closed for a second time period through the mobile terminal 20 or the vehicle multimedia 100;
the low-voltage lithium battery management module 300 converts the current time and the target time into the residual time and starts timing;
The low-voltage lithium battery management module 300 counts the off time, turns off the charge-discharge switch 30, and controls the static power consumption to 0;
The low-voltage lithium battery management module 300 counts to the closing time, closes the charge-discharge switch 30, and controls the static power consumption to the normal use level.
In the above-described embodiment, the user may set the opening and closing of the charge and discharge switch 30 at several minutes of the several months according to the schedule.
In one embodiment of the invention, the method for controlling the static power consumption of the low-voltage lithium battery comprises the following steps:
after the user parks and extinguishes the vehicle, the vehicle multimedia 100 detects the power state and the gear signal, determines that the vehicle is in a low-high voltage state and the gear is in a P gear, and transmits the parking signal to the low-voltage lithium battery management module 300. After the low voltage lithium battery management module 300 receives the signal, it starts the RTC timer for 1 hour. After counting 1 hour, the low-voltage lithium battery management module 300 performs the operation of turning off the charge/discharge switch 30. After 8 hours of time, the low-voltage lithium battery management module 300 performs the action of closing the charge/discharge switch 30.
The process realizes the intelligent control of the power consumption of the low-voltage lithium battery.
It should be noted that: whether the user sets timing or intelligently controls low-voltage energy consumption management, the situation of using the vehicle in advance exists. If the charge/discharge switch 30 is in the off state at this time, the user presses the hard-wired button 200 for 10 seconds, and the charge/discharge switch 30 is closed, and power supply is restored.
