Embodiment one: as shown in fig. 1, which is only one embodiment of the present utility model, an intelligent power supplementing method for a vehicle-mounted storage battery is suitable for an intelligent power supplementing system for a vehicle-mounted storage battery, wherein the system comprises an AGM storage battery, a storage battery sensor IBS, a body area controller BDM, a battery management unit BMS, a DC-DC converter and a whole vehicle controller VCU, and in the above system, the storage battery is an AGM storage battery, and the AGM storage battery is not layered compared with the conventional rich electrolyte, so as to be convenient for detecting the SOC (remaining power) thereof; the storage battery sensor IBS is arranged at the negative electrode of the AGM storage battery, and an intelligent switch is arranged between the storage battery sensor IBS and a storage battery negative electrode terminal;
the method comprises the following steps:
s1: judging whether the front cover is in an open state or not, if so, switching off the intelligent switch; otherwise, the intelligent switch is closed, and the step S2 is executed;
generally, the opening and closing signal of the front cover is obtained through the sensor, and then the sensor electrically connected to the intelligent switch is disposed at the front cover before executing step S1, so that when the front cover is opened, the sensor sends the sensing signal to the intelligent switch, and at this time, the intelligent switch turns off the negative electrode of the AGM battery, and then the battery sensor IBS cannot obtain the SOC data of the AGM battery, and the power-up operation of the AGM battery in steps S2 to S6 cannot be executed.
And when the step S1 is executed, every second preset time, the intelligent switch judges whether the front cover is in an open state, once the front cover is in the open state, the intelligent switch sends a forced shutdown instruction to the battery management unit BMS and the DC-DC converter when being disconnected, so that the electric shock danger of maintenance personnel caused by the fact that the battery management unit BMS and the DC-DC converter are supplying electricity to the AGM storage battery when the vehicle needs to be maintained and the front cover is opened can be effectively avoided, and whether the battery management unit BMS and the DC-DC converter are currently operated as the AGM storage battery to supply electricity or not is effectively prevented.
It should be noted that the sensors may be provided at the cover parts of the vehicle, which may touch the vehicle circuit, and these cover parts are considered to be the same as the front cover, and once either one of the cover parts or the front cover is opened, the intelligent switch is turned off, and the battery management part BMS and the DC-DC converter stop operating.
S2: the storage battery sensor IBS detects the SOC of the AGM storage battery every preset time interval and sends the SOC to the vehicle body domain controller BDM;
to prevent battery starvation due to excessive vehicle idle time, the battery sensor IBS acquires and sends an AGM battery SOC once every predetermined time interval (e.g., 24 hours every interval) to the body area controller BDM of the vehicle.
S3: the vehicle body domain controller BDM sends the SOC data of the AGM storage battery to the whole vehicle controller VCU through a message;
here, before executing step S3, the vehicle body domain controller BDM converts the AGM battery SOC data transmitted from the battery sensor IBS into internal signals, that is, analyzes the sensor signals transmitted from the battery sensor IBS and converts the sensor signals into data signals that can be recognized by the vehicle control unit VCU.
And when executing step S3, the vehicle body domain controller BDM sends the AGM battery SOC data to the vehicle controller VCU through a message, and wakes up the vehicle controller VCU.
S4: the vehicle controller VCU judges whether the SOC of the AGM storage battery is lower than a preset threshold value, if yes, the step S5 is executed; otherwise, not executing the operation;
before step S4 is performed, a predetermined threshold is set, and typically the predetermined threshold may be set manually, for example, 60% is set, that is, the AGM battery SOC received by the vehicle control unit VCU is lower than 0.6, and then power is applied to the AGM battery to supplement power.
S5: the whole vehicle controller VCU sends a power-on instruction to the battery management unit BMS and controls the DC-DC converter to work for supplementing power to the AGM storage battery;
after the battery management unit BMS receives the power-on instruction, the main relay for driving the AGM storage battery is closed, and at this time, the DC-DC converter can supplement power to the AGM storage battery.
S6: the VCU judges whether the whole vehicle is electrified to HV Ready; if yes, the battery management unit BMS and the DC-DC converter stop the power-on operation; otherwise, the step S5 is continued.
Here, in the process of supplementing power to the AGM battery, the battery sensor IBS still transmits the SOC information of the AGM battery at predetermined intervals to finally reach the vehicle controller VCU, and the vehicle controller VCU continuously monitors the SOC of the AGM battery until the vehicle is powered up to HV Ready, without power supplement, and the battery management unit BMS and the DC-DC converter stop working.
In addition, when step S6 is executed, during the process of powering up the whole vehicle to HV Ready, it is required to ensure that the motor is in an disabled state, if the motor is in an enabled state, that is, when the driver controls the vehicle host to issue a signal for enabling the motor to the whole vehicle controller VCU (that is, a signal for allowing feeding, only when the motor can rotate when the feeding enabling signal is valid), the power-up is stopped, and the battery management unit BMS and the DC-DC converter stop working, so as to avoid damaging the power supply when the motor rotates.
It should be noted that the battery sensor IBS needs to be used with the AGM battery at the same time, and the IBS sensor needs to be calibrated to increase the accuracy of detecting the SOC of the AGM battery, so that the accuracy of power-up detection is good; and just because the storage battery sensor IBS can directly measure AMG storage battery SOC, use storage battery SOC as intelligent power supply basis, do not regard as intelligent power supply basis through battery terminal voltage like before to can not frequently start the current journey and cause power battery electric quantity loss reduction duration.
According to the intelligent power supplementing method for the vehicle-mounted storage battery, the power supplementing detection is accurate, errors in measurement of the voltage of the storage battery end like a BMS are avoided, the SOC of the storage battery is directly used as an intelligent power supplementing basis, and the problem that the continuous voyage capability of the storage battery is reduced due to frequent power supplementing is effectively avoided; and also can prevent the electric shock hazard of maintenance personnel.

When the step S3 is executed, the vehicle body domain controller BDM sends the SOC data of the AGM storage battery to the whole vehicle controller VCU through a message through the CAN network;
similarly, when step S5 is executed, the whole vehicle controller VCU sends a power-on command to the battery management unit BMS through the CAN network, and controls the DC-DC converter to operate to supplement power to the AGM battery through the CAN network.
When step S5 is executed, the positive electrode of the DC-DC converter is connected to the positive electrode of the AGM battery, and the power is supplied.
As shown in fig. 2, the vehicle body domain controller BDM, the battery management unit BMS, and the DC-DC converter are all connected with the vehicle controller VCU through the CAN bus, without changing the vehicle connection line; the additionally arranged storage battery sensor IBS is connected with the vehicle body domain controller BDM through the LIN line, so that the characteristic that the vehicle body domain controller BDM can transmit information (an AGM storage battery SOC signal) can be effectively utilized; and the positive pole of the DC-DC converter and the positive pole of the AGM storage battery do not need to transmit signals, so that the vehicle circuit can be minimally improved through common power transmission line connection, and the cost is minimized in the whole power supplementing process.
