Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a battery control method, a battery control device and an automobile, and aims to realize self-maintenance of a vehicle battery.
As shown in fig. 1, an embodiment of the present invention provides a method for controlling a battery, which is applied to a battery management system BMS, and includes:
s11: receiving a battery balancing instruction sent by an intelligent vehicle-mounted terminal T-box;
s12: according to the battery balancing instruction, carrying out balance judgment on the battery cell of the battery at intervals of first preset time;
s13: when the judgment result is unbalanced, judging whether the current finished automobile meets the balance condition;
s14: and when the whole vehicle meets the balance condition, performing balance control on the battery cell, and stopping the balance control until the judgment result is balance.
That is to say, after receiving the battery equalization instruction, can judge the vehicle according to the balanced condition of presetting, just carry out balanced control to electric core when the vehicle satisfies balanced condition to guarantee the safety of vehicle. When the result of the cell balance judgment is balance, the balance control is stopped in time, and the self-maintenance of the battery is completed, so that the service life of the battery is prolonged.
Optionally, the balancing, according to the battery balancing instruction, the determining, at every first preset time, of the electric core of the battery includes:
detecting the voltage of each electric core of the battery;
judging whether the absolute value of the difference value between the voltages of the battery cells is larger than a preset value or not according to the detection result;
when the absolute value of the difference value is larger than a preset value, judging that the result is unbalanced; otherwise, the judgment result is balance.
Specifically, whether unbalance appears in every electric core voltage of BMS detectable battery, if unbalance electric core appears then begin to judge whether satisfy the equilibrium condition, prepare to carry out initiative equilibrium. If the judgment result is balance, the relevant balance operation is not needed.
In more detail, the absolute value of the difference between the voltages of the battery cells may be compared with a preset value, and whether the voltages are balanced may be determined according to the comparison result. Wherein the preset value can be obtained according to specific vehicle calibration.
Optionally, the equalization condition comprises: the current SOC of the vehicle is larger than the preset electric quantity, and the whole vehicle mode of the vehicle is a parking mode and/or the current parking of the vehicle exceeds a second preset time.
It should be noted that, in the control method for a battery according to an embodiment of the present invention, an equalization condition may be set, and when the vehicle meets the equalization condition, the vehicle is allowed to perform active equalization, so as to ensure that the vehicle can perform equalization operation in a safe state. For example, after the active equalization is controlled to be started, it may be set that the SOC of the vehicle is greater than a preset electric quantity (e.g., 5%), or it may be further limited that the vehicle needs to be in a parking mode to perform the active equalization control, so as to ensure the safety of the vehicle. The whole vehicle mode can be acquired through the VCU.
In addition, considering that the battery temperature of the vehicle which is just parked does not reach the stable state yet, the vehicle can be set to wait for a certain time (namely the second preset time), and after the battery temperature and the room temperature reach the balance, the equalization operation is carried out.
That is, the equalization condition may be further limited, for example, a judgment about the time when the vehicle has been parked is set, and if the vehicle is parked for more than the set second preset time, the equalization condition is considered to be satisfied, and then the equalization operation performed on the vehicle is more effective. The second preset time can be calibrated according to the actual condition of the vehicle, and can be set to 1 hour, for example.
In the embodiment of the invention, the voltage of each battery cell of the battery is kept within a certain difference value by carrying out balance control on the battery cells; the safety of the vehicle during the balance control is ensured by setting the balance condition; the BMS can synthesize the voltage of each battery cell, and can start or stop active equalization control, thereby prolonging the service life of the battery.
As shown in fig. 2, an embodiment of the present invention further provides a battery control method, which is applied to an intelligent vehicle-mounted terminal T-box, and includes:
s21: receiving a battery maintenance instruction;
s22: according to the battery maintenance instruction, awakening the first controller every other third preset time; the first controller comprises a battery management system BMS and/or a vehicle control unit VCU;
s23: and sending a battery balancing instruction to the BMS.
Optionally, the battery maintenance instruction is sent by a vehicle central control large screen or a mobile terminal.
That is, a vehicle user may send a battery maintenance instruction to the vehicle through a vehicle central control large screen or a mobile terminal (e.g., a mobile phone), indicating that the user is willing to authorize the vehicle to perform maintenance on the battery. After receiving the battery maintenance instruction, the T-box may wake up each controller (i.e., the first controller) required for performing the balancing control at regular intervals (i.e., the third preset time), and the woken-up controllers cooperate with each other (as shown in fig. 5, which is a relationship diagram of each controller), determine whether the battery needs the balancing control, whether the balancing condition for starting the balancing control is satisfied, and control and execute the balancing operation when the balancing condition is satisfied, thereby implementing self-maintenance of the battery. The third preset time can be calibrated according to the actual condition of the vehicle, and can be set to 8 hours, for example.
Optionally, the third preset time is a continuous time of the vehicle in a parking state.
That is to say, after the user sets the vehicle through the battery maintenance instruction, the T-box wakes up the first controller, starts timing when the entire vehicle mode is the parking mode, and wakes up the first controller after each timing reaches the third preset time, so as to perform relevant judgment and operation for equalization. If the vehicle is changed from the parking mode to other modes (such as a running mode) during timing, the timing is cleared; and when the vehicle is converted into the parking mode, the T-box restarts timing.
It should be further noted that, after the user sets whether to start the battery self-maintenance on the vehicle central control large screen, the battery self-maintenance can be synchronously provided to the mobile terminal through the T-BOX; similarly, after the user sets the battery self-maintenance on or off on the mobile terminal, for example, after the battery self-maintenance is started or turned off by operating the APP installed on the mobile phone, the large screen of the vehicle central control unit can be synchronously provided through the T-BOX.
Further, the first controller may be powered by a DCDC converter after it is awakened. Among them, the DCDC converter may be a 12V inverter.
More specifically, as shown in fig. 6, it is a flowchart of a control method according to an embodiment of the present invention:

s602: the T-BOX receives a battery maintenance instruction;
s603: the T-BOX wakes up each controller every third preset time (such as 8 hours) and sends a battery balancing instruction to the BMS;
s604: after receiving the battery balancing instruction, the awakened BMS detects whether the voltage of each battery cell of the battery is unbalanced, namely, the battery cells of the battery are subjected to balancing judgment; if yes, go to S605; otherwise, executing S611;
s605: judging whether the SOC of the vehicle is larger than a preset electric quantity (such as 5%); if yes, go to S606; otherwise, executing S611;
s606: judging whether the whole vehicle mode of the vehicle is a parking mode or not; if yes, executing S607; otherwise, executing S611;
s607: judging whether the vehicle stops for a second preset time (such as 1 hour) or not until the judgment result is yes;
s608: the BMS performs balance control on the battery cell;
s609: the BMS controls the DCDC to supply power to each controller;
s610: carrying out balance judgment on the battery core of the battery; judging whether the absolute value of the difference value between the voltages of the battery cells is smaller than a preset value or not; if yes, indicating balance, executing S611; otherwise, go to S608;
