Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a first aspect, the embodiment of the invention provides a storage battery power supplementing method.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for supplementing power to a storage battery according to an embodiment of the present invention. As shown in fig. 1, in an embodiment, a method for supplementing power to a battery includes:
step S10, when the remote information processor T-BOX detects that the SOC value of the storage battery is smaller than a first preset value and the time difference between the current time and the last time of initiating the power supplementing request is larger than a preset time difference, the power supplementing request is sent to the VCU of the whole vehicle controller;
in this embodiment, the telematics unit T-BOX obtains the SOC value of the battery via the battery level sensor. Soc (state of charge), which is the state of charge, is used to reflect the remaining capacity of the battery, and is numerically defined as the ratio of the remaining capacity to the battery capacity, expressed as a percentage. The value range of the battery charging indicator is 0-1, when the SOC is 0, the battery is completely discharged, and when the SOC is 1, the battery is completely charged. And after the SOC value of the storage battery is obtained, comparing the SOC value of the storage battery with a first preset value. The first preset value is set according to actual needs, for example, set to 0.5. When the SOC value of the storage battery is smaller than the first preset value, whether the time difference between the current time and the last time of initiating the power supplementing request is larger than a preset time difference is judged again, wherein the preset time difference is set according to actual conditions, for example, the preset time difference is set to be 5 hours. If the SOC value of the storage battery is smaller than a first preset value and the time difference between the current time and the last time of initiating the power supplementing request is larger than the preset time difference, the T-BOX sends the power supplementing request to the gateway, so that the gateway forwards the power supplementing request to the VCU and the high-voltage power battery to wake up the VCU and the high-voltage power battery. The telematics T-BOX may perform the above-mentioned detection step every preset time period (e.g., 3 hours).
Step S20, when the VCU receives the power supplementing request, detecting whether the power supplementing condition is met;
in this embodiment, when the VCU receives the power supplement request, it needs to determine whether to enter the power supplement process according to the vehicle state.
Specifically, in an embodiment, the step of detecting whether the condition of entering the power supply is satisfied includes:
detecting whether the following conditions are met simultaneously:
condition a, no other wake-up signal is received;
the condition B is that the high-voltage power battery has no fault;
the condition C is that the SOC value of the high-voltage power battery is greater than a second preset value;
condition D, vehicle speed is zero;
and if the conditions A to D are simultaneously met, determining that the condition of entering power supply is met.
In this embodiment, when the VCU does not receive other wake-up signals and the vehicle speed is zero, it indicates that the vehicle is currently in a sleep state, and in this case, if the high-voltage power battery has no fault and the SOC value of the high-voltage power battery is greater than the second preset value, it is determined that the storage battery can be recharged by the high-voltage power battery, that is, it is determined that the condition of entering power replenishment is satisfied. After the high-voltage power battery is awakened, the fault information and the SOC value of the high-voltage power battery are fed back to the VCU.
Step S30, when the condition of entering power supply is met, the VCU controls the high-voltage power battery to supply power to the storage battery, and feeds back power supply starting state information to the T-BOX;
in the embodiment, when the condition of entering power supply is determined to be met, the VCU controls the high-voltage power battery to supply power to the storage battery, and feeds back power supply starting state information to the T-BOX.
As shown in fig. 2, fig. 2 is a schematic view of a scene of supplying power to the storage battery. As shown in fig. 2, the T-BOX acquires the SOC value of the low-voltage battery through the electric quantity sensor, and then sends a power supplement request to the vehicle control unit VCU through the Gateway (GM), and the VCU controls the high-voltage power battery BMS to supply power to the buck inverter DCDC so that the DCDC can supplement power to the low-voltage battery.
Step S40, in the power supply process, the VCU detects whether the condition of quitting power supply is met;
in this embodiment, in the power supply process, whether the condition of quitting the power supply is met or not needs to be judged according to the vehicle state.
Specifically, in an embodiment, the step of detecting whether the VCU satisfies the condition of exiting power supply includes:
the VCU detects whether any of the following conditions is satisfied:
the condition E is that the SOC value of the high-voltage power battery is smaller than or equal to a second preset value;
under the condition F, the high-voltage power battery has faults;
under the condition G, after the high-voltage power battery is electrified, the SOC value of the storage battery is not increased after a preset time;
conditional H, VCU is that no power-on request heartbeat packet sent by the T-BOX is received at a specified time;
condition I, receiving other wake-up signals;
the condition J is that the SOC value of the storage battery is larger than a third preset value;
determining that an exit power supplement condition is satisfied when any one of the conditions E to J is satisfied.
In this embodiment, when the SOC value of the high-voltage power battery is less than or equal to the second preset value, it indicates that the electric quantity of the high-voltage power battery is insufficient, and therefore the storage battery cannot be recharged by the high-voltage power battery any more, and therefore when the condition E is satisfied, it is determined that the condition for withdrawing from the recharging process is satisfied.
When the high-voltage power battery has a fault, the storage battery cannot be supplemented with electricity through the high-voltage power battery, so that when the condition F is met, the condition of quitting electricity supplementation is determined to be met.
After the high-voltage power battery is electrified, the SOC value of the storage battery is not increased after a preset time, which indicates that components such as a power supply circuit, the storage battery and the like may have faults, so that the storage battery cannot be supplied with power, and therefore when the condition G is met, the condition of quitting power supply is determined to be met. Wherein the preset time period is set according to actual needs, for example, 2 minutes.
After the T-BOX sends the power supplementing request, the power supplementing request heartbeat packet is continuously sent to the VCU, if the VCU does not receive the power supplementing request heartbeat packet sent by the T-BOX at a specified time, the situation that the communication between the T-BOX and the VCU fails is shown, and the information interaction between the T-BOX and the VCU is no longer supported, so that the storage battery can not be supplemented any more, and the condition of quitting power supplementing is determined to be met when the condition H is met.
When other wake-up signals are received, such as an alternating current charging wake-up signal, a direct current charging wake-up signal or a door state opening signal, it is determined that the user needs to operate the vehicle, and the storage battery does not need to be recharged, so that when the condition I is met, the condition of quitting recharging is determined to be met.
When the SOC value of the storage battery is larger than the third preset value, the circuit of the storage battery is enough at the moment, and the power supply does not need to be carried out on the storage battery. Therefore, when the condition J is met, the condition of quitting the power supply is determined to be met. Wherein, the third preset value is set according to actual needs, for example, set to 0.9.
And step S50, when the condition of quitting the power supply is met, the VCU controls the high-voltage power battery to stop supplying power to the storage battery, and feeds back the information of the quitting power supply state to the T-BOX.
In the embodiment, when the condition of quitting the power supply is met, the VCU controls the high-voltage power battery to stop supplying power to the storage battery, and feeds back the information of the quitting power supply state to the T-BOX.
Further, in one embodiment, step S50 includes:

in this embodiment, when the condition of quitting power supply is met by meeting any one of the conditions E to G, it is described that the storage battery cannot be supplied with power because the high-voltage power battery has low power or a fault, so that the first power supply quitting state information is fed back to the T-BOX, and the T-BOX further feeds back the first power supply quitting state information to the user terminal, so that a user at the user terminal side can know that the high-voltage power battery has low power or a fault in time and process the information in time.
When the condition H is met, the VCU controls the high-voltage power battery to stop supplying power to the storage battery, and feeds back second power supply quitting state information to the T-BOX;
in this embodiment, when the condition H is satisfied and the condition H for power supply withdrawal is satisfied, it indicates that the power supply of the battery cannot be performed because the communication between the T-BOX and the VCU has failed, and therefore the second power supply withdrawal status information is fed back to the T-BOX, so that the T-BOX further feeds back the second power supply withdrawal status information to the user terminal, so that the user at the user terminal side can know that the communication between the T-BOX and the VCU has failed in time and process the failure in time.
When the condition I is met, the VCU controls the high-voltage power battery to stop supplying power to the storage battery, and feeds back third power supply quitting state information to the T-BOX;
in this embodiment, when the condition I is satisfied and the condition of quitting power supply is satisfied, it indicates that the user needs to operate the vehicle at present, and does not need to supply power to the battery any more, and the vehicle is in a normal quitting condition, so that the third quitting power supply state information is fed back to the T-BOX, so that the T-BOX feeds back the third quitting power supply state information to the user terminal, so that the user knows that the vehicle is operated, and thus the power supply to the battery is stopped.
And when the condition J is met, the VCU controls the high-voltage power battery to stop supplying power to the storage battery, and feeds back fourth power supply quitting state information to the T-BOX.
In this embodiment, when the condition J is satisfied and the condition for withdrawing from the power supply is satisfied, it is described that the electric quantity of the storage battery is already sufficient and the storage battery does not need to be supplied with power, so that the fourth withdrawing from the power supply state information is fed back to the T-BOX, so that the T-BOX further feeds back the fourth withdrawing from the power supply state information to the user terminal, so that the user can know that the electric quantity of the storage battery is sufficient.
In the embodiment, when the telematics unit T-BOX detects that the SOC value of the storage battery is smaller than a first preset value and the time difference between the current time and the last time of initiating the power supplementing request is larger than a preset time difference, the power supplementing request is sent to the VCU of the vehicle control unit; when the VCU receives the power supplementing request, whether the power supplementing condition is met or not is detected; when the condition of entering power supply is met, the VCU controls the high-voltage power battery to supply power to the storage battery, and feeds back power supply starting state information to the T-BOX; in the power supplementing process, the VCU detects whether the condition of quitting the power supplementing is met or not; and when the condition of quitting the power supply is met, the VCU controls the high-voltage power battery to stop supplying power to the storage battery, and feeds back the quitting power supply state information to the T-BOX. Through this embodiment, when satisfying entering the condition of mending the electricity, mend the electricity for the battery, when satisfying to withdraw from the condition of mending the electricity, stop to mend the electricity for the battery, realize the nimble control to the battery mends the electricity, avoided the condition of battery feed as far as to take place.
