Description

TBOX chip backup battery power management method, control system and storage medium
Technical Field
The invention relates to a TBOX chip backup battery, in particular to a TBOX chip backup battery electric quantity management method, a control system and a storage medium.
Background
With the development of the car networking technology, in order to improve user experience and improve the management efficiency of the electric vehicle, when a 3-level alarm occurs on the vehicle, data about 30s before and after a fault occurrence time point should be reported. The data before the fault occurs should be transmitted in a reissue mode so as to more accurately and quickly locate the fault reason and find a solution. The functions of uploading the vehicle running information to the enterprise platform and the public platform are realized by a 4G TBOX (Telematics BOX) chip. Generally, the 4G TBOX chip is powered by a main power supply (12V small battery or DCDC), and when the 12V small battery and the DCDC cannot supply power, the backup battery supplies power. At present, the 4G TBOX chip power supply system has two modes of switching from a main power supply to a backup battery: 1. identifying whether the main power supply of the vehicle is abnormally powered down or not by means of a TBOX main control chip, and controlling to start a backup battery through software when the power down is identified; 2. and the power supply is automatically switched to a backup battery through a hardware principle. In the actual use process, the self-discharge phenomenon exists even if the backup battery does not supply power to the 4G TBOX chip in any mode. If the electric quantity of the backup battery is not managed, the backup battery has the phenomenon that the fault data cannot be sent when the electric quantity of the 12V small storage battery and the DCDC are abnormally powered down. Meanwhile, if the service life of the backup battery is not monitored, when the backup battery cannot be charged after an irreversible fault occurs, users and vehicle enterprises cannot sense the irreversible fault, and fault data cannot be successfully issued.
CN112911570A discloses a vehicle-mounted device and a calling method of the vehicle-mounted device, where the vehicle-mounted device includes a built-in backup battery for providing power to the vehicle-mounted device, a power supply unit, a bluetooth unit, and a control unit, and the control unit is configured to detect a voltage of a power supply path of a vehicle-mounted storage battery; determining that the voltage is smaller than a preset value, and controlling a power supply unit to switch a power supply of the vehicle-mounted equipment from a storage battery in the vehicle to a built-in backup battery, wherein the voltage provided by the built-in backup battery is smaller than the voltage provided by the storage battery in the vehicle; the control unit is further used for sending an emergency call instruction to the first device through the Bluetooth unit, wherein the emergency call instruction is used for indicating the first device to call the second device through a mobile communication network corresponding to the user identification identifier of the first device, and therefore standby time and conversation time of the vehicle-mounted device are improved. Needless to say, the technical solution disclosed in the above patent document is a useful attempt in the technical field.
Disclosure of Invention
In view of this, an object of the present invention is to provide a method, a control system and a storage medium for managing the power of a backup battery of a TBOX chip, which can prompt a user in time after the number of failures reaches a certain frequency, and simultaneously can maintain the power of the backup battery at a higher level, so as to ensure that the backup battery can provide power for a 4G TBOX chip for a longer time when a main power supply fails to provide power, prevent the power of the backup battery from being too low due to a self-discharge phenomenon, and prevent the failure data from being unable to be reissued due to the power of the backup battery being too low when the main power supply fails to provide power.
The invention discloses a TBOX chip backup battery power management method, which comprises the following steps:
the control system is awakened;
reading the occurrence frequency N of failure faults;
judging whether the failure fault occurrence frequency N is greater than a preset value or not, and prompting a user if the failure fault occurrence frequency N is greater than the preset value;
if the failure fault occurrence frequency N is not greater than a preset value, acquiring working condition parameters of the backup battery, wherein the working condition parameters comprise battery voltage;
when the charging condition of the backup battery is met, charging is carried out, and the charging time is recorded from zero;
in the charging process, if the charging time is not more than to and the battery voltage is not more than UO, continuing to charge;
in the charging process, if the charging time is longer than to and the battery voltage is still smaller than Ue, determining that a charging failure fault occurs; wherein UO > Ue;
in the charging process, if a charging failure fault occurs, the number of times of occurrence of the updating failure fault is N = N +1;
and judging whether the control system needs to be dormant, if so, storing the failure fault occurrence frequency N and enabling the control system to be dormant.
Through the technical scheme, the user can be reminded in time when the failure fault occurs for too many times, the electric quantity of the backup battery can be maintained at a higher level, when the battery voltage is greater than UO, the electric quantity of the backup battery can provide power for the 4G TBOX chip for a longer time when the main power supply cannot supply power, the situation that the electric quantity of the backup battery is too low due to the self-discharge phenomenon is prevented, and the situation that the fault data cannot be sent again due to the too low electric quantity of the backup voltage when the main power supply cannot supply power is prevented; meanwhile, through the technical scheme, whether the backup battery can be normally charged can be monitored in the charging process, when the battery voltage after charging for a certain time still does not reach UO, the battery electric quantity after charging still does not reach a high level, at the moment, whether the battery voltage is smaller than UO is judged, if the charging time is longer than to and the battery voltage is still smaller than UO, the battery electric quantity after charging for a certain time still does not reach the minimum required quantity for supplying power for the 4G TBOX chip is judged, the charging failure fault is determined to occur, and the occurrence frequency of the updating failure fault is N = N +1.

Through the technical scheme, when the backup battery can normally work, the accumulated failure occurrence frequency is subtracted once, and the user can be reminded after the failure occurrence frequency reaches a certain frequency (namely, failure failures occur continuously for multiple times), so that false alarm is prevented. One of the criteria for judging the normal operation of the backup battery is as follows: the electric quantity of the backup battery is maintained at a higher level within a certain charging time, the electric quantity of the backup battery can supply power for a 4G TBOX chip for a longer time, namely the charging time is not more than to and the battery voltage is more than UO; the second criterion for judging the normal operation of the backup battery is as follows: after charging for a certain time, the battery capacity can reach the minimum required capacity for supplying power to the 4G TBOX chip, namely the charging time is more than to and the battery voltage is not less than Ue.

Further, in the present invention, it is preferable that,

and if the resistance value R of the battery temperature sensor meets the condition that Rmin is not more than R and not more than Rmax, determining that the failure fault of the battery temperature sensor does not occur.
Further, in the present invention,
the step of judging whether the charging condition of the backup battery is met according to the acquired working condition parameters comprises the following steps:
if the battery temperature T meets Tmin and Tmax, and the battery voltage is not greater than UO, determining that the charging condition of the backup battery is met;
and if the battery temperature T does not meet Tmin and Tmax or the battery voltage is greater than UO, determining that the charging condition of the backup battery is not met.
If the battery temperature T is too high and the backup battery is easy to damage, through the technical scheme, whether the battery can be charged or not and whether the battery needs to be charged or not can be judged.
Further, the method also comprises the following steps:
in the charging process, if the charging time is not more than to and the battery voltage is less than Ui, charging in a constant current charging mode;
in the charging process, if the charging time is not more than to, the battery voltage is not less than Ui and the battery voltage is not more than Uo, charging in a constant current charging mode;
wherein Uo > Ui.
Further, the method also comprises the following steps:
judging whether the main power supply has a power supply condition;
if the main power supply does not have the power supply condition, the backup battery supplies power to the TBOX chip;
and if the main power supply has the power supply condition, the main power supply supplies power to the backup battery and the TBOX chip.
