Abstract
Description
Technical Field

[0002] With the development of new energy vehicles, the problem of battery power loss has become more and more serious, especially when used in northern winter. The effective capacity of the battery is greatly reduced. After the vehicle has been stationary for a period of time, due to Over The Air Technology (OTA) upgrades and abnormal wake-up of the controller causing the entire vehicle control to be unable to sleep, the battery is insufficient and the vehicle cannot be started. This phenomenon frequently occurs, becoming a pain point of concern in the industry.
[0003] At this time, in order to solve the problem of insufficient battery power causing the vehicle to be unable to power on, intelligent charging technology came into being. At present, major OEMs in the industry usually wake up the vehicle regularly when the vehicle is stationary for new energy vehicles. After waking up, if the battery power is sufficient, there is no need to charge. If the battery power is insufficient, the DC / DC converter is temporarily woken up to charge the battery through the power battery, thereby reducing the risk of vehicle power feeding.
[0004] However, in the above scheme, since the user cannot perceive the usage of the vehicle battery, he can only use the method of waking up the vehicle at a fixed time to detect the battery power, thereby increasing the power consumption of the low-voltage electrical appliances of the whole vehicle and causing power waste.

[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.
[0050] The first embodiment of the present application relates to a power feeding early warning method. Figure 1 is a flow chart of a power feeding warning method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:
[0051] Step 101, when it is detected that the vehicle is powered off, the target information of the vehicle is obtained, the target information including the battery terminal voltage information and the external temperature information, the current remaining capacity of the power battery, and the power consumption of the target controller.
[0052] In the embodiment of the present invention, when the vehicle is powered off in the OFF gear, the power-off signal is identified and judged by the regional controller, and then the internal main control chip MCU of the regional controller sends the battery remaining capacity (State Of Charge, SOC) monitoring and detection requirements to the CAN bus through the (CAN with Flexible Data rate, CANFD) transceiver according to the set algorithm. After the battery management system (Battery Management System, BMS) of the power battery receives the signal, it detects its own remaining capacity SOC for the last time, and also collects the vehicle's external temperature signal on the CAN bus through the CAN FD transceiver, and obtains the vehicle's external temperature information at the moment of locking by filtering and identifying the message address. In addition, the battery terminal voltage information and the power consumption of the target controller are also obtained. Among them, the target controller refers to the controller related to charging. CAN FD can be simply regarded as an upgraded version of the traditional CAN. Compared with the CAN bus technology, the advantages of CAN FD are: supporting variable rates and supporting longer data lengths.
[0053] It should be noted that, because the embodiment of the present invention is to determine the power feeding time period of the vehicle, the vehicle target information obtained also includes: shallow sleep dark current value, deep sleep dark current value, delayed sleep power consumption of electrical appliances, battery self-discharge data and DC / DC conversion efficiency, among which dark current refers to the current that is still flowing when the car is in a stationary sleep state, also known as "static current". Because of the existence of these dark currents and the natural discharge of the battery, the vehicle will be parked for a long time, resulting in insufficient battery capacity, car power feeding, and inability to start. The stationary sleep state of the car includes: shallow sleep and deep sleep, so the vehicle target information obtained includes shallow sleep dark current value, deep sleep dark current value and battery self-discharge data. In addition, when the electrical appliance receives the sleep signal, if the user still needs to use it at this time, it will cause the electrical appliance to be delayed in sleep. The embodiment of the present invention also needs to determine the number of times the power battery charges the battery, so the conversion efficiency of the intermediate DC / DC converter is also the target information that needs to be obtained. It should be noted that the shallow sleep dark current value, deep sleep dark current value, delayed sleep power consumption of electrical appliances, battery self-discharge data and DC / DC conversion efficiency can all be obtained through preliminary experiments and calibrated, and then can be directly called when determining the vehicle power feeding time and the number of intelligent power replenishment times.
[0054] Step 102, determining the target effective capacity of the battery according to the battery terminal voltage information and the external temperature information.
[0055] The embodiment of the present invention is pre-set at different external temperatures, and after measuring the effective capacities corresponding to different battery terminal voltages, a one-to-one corresponding table is formed. Therefore, subsequently, only the battery terminal voltage information and the external temperature information need to be obtained to look up the table to obtain the corresponding target effective capacity of the battery.
[0056] It should be noted that, because the capacity of the battery is related to the discharge current and the temperature of the electrolyte, if the discharge current is too large, the amount of active substances and sulfuric acid participating in the reaction per unit time will increase. Due to the rapid consumption of sulfuric acid in the pores of the plate, the sulfuric acid outside the plate has no time to penetrate into the inside of the plate, causing the electrolyte density in the pores of the plate to drop too fast, and the terminal voltage of the battery to drop too fast, reaching the termination voltage in advance; since sulfuric acid has no time to penetrate into the inside of the plate, it is reflected on the surface of the plate, and the generated lead sulfate also adheres to the surface of the plate, hindering sulfuric acid from penetrating into the plate, then the active substances inside the plate cannot be fully utilized, and the capacity of the battery is reduced. Therefore, the smaller the terminal voltage of the battery, the smaller the corresponding effective capacity of the battery. When the electrolyte temperature is low, the viscosity will increase and the permeability will decrease, resulting in a decrease in the capacity of the battery. When the electrolyte temperature is low, the solubility and ionization of the electrolyte will also decrease, which will also aggravate the decrease in the battery capacity. However, the electrolyte temperature is not easy to measure, so the influence of temperature on the battery capacity can be determined by obtaining external temperature information.
[0057] Step 103: determine a time period for power feeding according to the target effective capacity of the battery and the power consumption of the target controller, and send a first power feeding warning.
[0058] In the embodiment of the present invention, after determining the target effective capacity of the battery, the time period for power feeding is determined based on the target effective capacity and the power consumption of the target controller. Because the power consumption of the target controller will not be a constant value, a time period is obtained. The power consumption of the target controller corresponds to the power loss of the relevant controller during the charging process evaluated by recording the charging time when charging the battery.
[0059] After determining the time period for power feeding, the first power feeding warning will be sent to TBOX via the CAN bus for the first SMS reminder. The reminder here can be a reminder of the approaching time, such as a reminder 24 hours before the power feeding time period, so as to give the user sufficient time to arrange charging for the vehicle, or it can be a warning reminder sent directly after the power feeding time period is detected after the car is dormant, and then set as a to-do message on the mobile phone to remind the user regularly, which is not specifically limited in the present invention.
[0060] Step 104, determining the number of intelligent charging times according to the current remaining capacity of the power battery.
[0061] After determining the vehicle's power feeding time period, the embodiment of the present invention will also charge the storage battery through the power battery. Because the power battery charges the storage battery based on its own current remaining capacity, the number of intelligent charging times is determined based on the current remaining capacity of the power battery. It should be noted that before determining the number of intelligent charging times of the power battery as the storage battery, it is first necessary to determine whether the power battery at this time can charge the storage battery. If it can, the number of times that the storage battery can be charged will be determined based on the current remaining capacity of the power battery. If the current remaining power of the power battery is low at this time and the storage battery can no longer be charged, the user is reminded to charge the power battery in time.
[0062] Step 105: When it is detected that the number of intelligent power replenishment times is 1, a second power feeding warning is sent.
[0063] In the embodiment of the present invention, an internal counter is set to display the remaining number of smart charging times, and the initial value of the internal counter is set to the number of smart charging times calculated in the above steps. If the number of smart charging times calculated in the above steps is N (N≥2), the initial value of the internal counter is N. Each time the smart charging is triggered, the internal counter is reduced by one. For example, after the smart charging is triggered for the first time, the value on the internal counter is N-1. After the smart charging is triggered for the second time, the value on the internal counter is N-2, and so on, until the value of the internal counter is 1, which means that there is only one smart charging time left. At this time, it is necessary to wake up TBOX again, and then send a second power feeding warning to TBOX, so that TBOX sends a text message to the car owner's mobile phone to remind him to charge as soon as possible again.
[0064] Specifically, when it is detected that the number of intelligent power supplement times is 1, before sending the second power feeding warning, it also includes:
[0065] Set the initial count of the counter according to the number of intelligent power replenishment times;
[0066] When the triggering of intelligent power replenishment is detected, the internal counter is reduced by one.
[0067] The present invention obtains the target information of the vehicle when it detects that the vehicle is powered off, wherein the target information includes the battery terminal voltage information and the external temperature information, the current remaining capacity of the power battery, and the power consumption of the target controller; determines the target effective capacity of the battery according to the battery terminal voltage information and the external temperature information; determines the time period for power feeding according to the target effective capacity of the battery and the power consumption of the target controller, and sends a first power feeding warning; determines the number of intelligent power replenishments according to the current remaining capacity of the power battery; and sends a second power feeding warning when it is detected that the number of intelligent power replenishments is 1. The present invention obtains the target information of the vehicle after the vehicle is powered off, and then determines the time period for power feeding of the vehicle according to the target information, and sends a first power feeding warning to remind the owner of the estimated power feeding time, and determines the number of intelligent power replenishments at the same time, and sends a second power feeding warning when it is detected that the number of intelligent power replenishments is 1, and reminds the owner to charge as soon as possible again. Through double reminders, the risk of power feeding of the vehicle is greatly reduced, and there is no need to wake up the vehicle regularly, which increases the power consumption of the low-voltage electrical appliances of the whole vehicle and saves electricity.
[0068] The second embodiment of the present application relates to a power feeding early warning method, Figure 2 is a flow chart showing another power feeding warning method according to an exemplary embodiment. Figure 2 As shown, the following steps are included:
[0069] Step 201, when it is detected that the vehicle is powered off, the target information of the vehicle is obtained, the target information including the battery terminal voltage information and the external temperature information, the current remaining capacity of the power battery, and the power consumption of the target controller.
[0070] It should be noted that, in the embodiment of the present invention, the above step 201 refers to the foregoing discussion and will not be repeated here.
[0071] Step 202: Collect a plurality of different external temperatures.
[0072] In the embodiment of the present invention, the target effective capacity of the battery is determined by looking up a table according to the battery terminal voltage information and the external temperature information. Therefore, the supplier performs a large number of measurements on the battery at different temperatures in the early stage, and thus collects multiple different external temperatures, such as: 25°C, 0°C, -10°C, -20°C, and -30°C.
[0073] Step 203 , measuring the effective capacity of the battery corresponding to different battery terminal voltages for a plurality of different external temperatures.
[0074] In the embodiment of the present invention, the battery supplier conducts a large number of measurements on the battery at different temperatures, obtains the effective capacity corresponding to different terminal voltages at different temperatures, and forms a one-to-one corresponding table, which is convenient for subsequent acquisition of the battery terminal voltage information and the external temperature information, and then the table can be looked up to determine the target effective capacity of the battery. Among them, at the same temperature, different battery terminal voltages correspond to different effective capacities of the battery, and the same battery terminal voltage at different temperatures corresponds to different effective capacities of the battery, so the external temperature, the battery terminal voltage and the measured effective capacity of the battery must be uniquely matched.
[0075] In addition, during the measurement process, attention should be paid to the effect of the floating voltage on the battery terminal voltage, and through a large amount of measured data, the floating pressure coefficient of the battery under full charge state is integrated. Among them, the floating pressure is called the floating charge voltage, which refers to the voltage maintained by the battery after it is fully charged, and the capacity is maintained by compensating for the self-discharge of the battery. The voltage can be kept constant throughout the operation of the battery (for example, in a car battery), or the voltage can be maintained at a specific charging stage of the charger. The appropriate floating voltage will vary greatly with the changes in the battery's chemistry and structure and the ambient temperature.
[0076] Step 204, determining the target effective capacity of the battery according to the battery terminal voltage information and the external temperature information.
[0077] The logic algorithm inside the regional controller of the embodiment of the present invention obtains the battery terminal voltage information by scanning through the AD digital-to-analog conversion interface according to the table lookup method, obtains the external temperature information according to the external temperature sensor, and obtains the corresponding battery target effective capacity according to the temperature range.
[0078] Step 205: determine a time period for power feeding according to the target effective capacity of the battery and the power consumption of the target controller, and send a first power feeding warning.
[0079] In the embodiment of the present invention, the battery supplier charges the battery within the agreed range at 25°C, 0°C, -10°C, -20°C, and -30°C, and records the charging time and inputs it to the OEM. The purpose of this time is to estimate the charging time of each intelligent power replenishment, and then evaluate the power loss of the relevant target controller during the charging process, so as to accurately evaluate the battery feeding time. The specific steps include:
[0080] Obtaining the charging time for battery charging to be completed for a plurality of different external temperatures;
[0081] The power consumption of the target controller is determined based on the charging time.
[0082] Therefore, the power loss of the target controller has corresponding values at different temperatures, and these can be directly obtained by looking up the table without measuring again. The first power feeding warning sent can be presented in various ways such as voice, text, picture, video, etc., and the present invention does not make specific limitations here.
[0083] Step 206, determining the number of intelligent charging times according to the current remaining capacity of the power battery.
[0084] Step 207: When it is detected that the number of intelligent power replenishment times is 1, a second power feeding warning is sent.
[0085] It should be noted that, in the embodiment of the present invention, the above steps 206 to 207 refer to the foregoing discussion and will not be repeated here.
[0086] A third embodiment of the present application relates to a power feeding early warning method. Figure 3 yes Figure 1 The flowchart of step 104 in a power feeding warning method according to an exemplary embodiment is shown as follows. Figure 3 As shown, the following steps are included:
[0087] Step 301, obtaining the minimum remaining capacity of the power battery.
[0088] The embodiment of the present invention determines the number of intelligent charging times according to the current remaining capacity of the power battery, but the power battery does not charge the storage battery indefinitely, because the power battery also needs to provide a power source for the vehicle. If the power battery fails to feed power, the vehicle will be unable to drive and there is a risk of breaking down. Therefore, a charging threshold is set for the power battery, that is, the minimum remaining capacity of the power battery.
[0089] Step 302 : Generate the available discharge capacity of the power battery according to the current remaining capacity of the power battery and the minimum remaining capacity of the power battery.
[0090] In the embodiment of the present invention, after determining the minimum charging threshold for the power battery, that is, the minimum remaining capacity of the power battery, the available discharge capacity of the power battery is generated according to the current remaining capacity of the power battery and the minimum remaining capacity of the power battery. For example, the current remaining capacity of the power battery is SOC1, and the minimum remaining capacity of the power battery is SOC2. If SOC1 is greater than SOC2, the available discharge capacity of the power battery can be generated as SOC1-SOC2.
[0091] Step 303, obtaining the minimum protection power and the charging termination power of the battery.
[0092] In the embodiment of the present invention, the storage battery is recharged by the power battery. At this time, it is necessary to determine the initial time and the end time of the recharge, which can be determined by the minimum protection power of the battery and the termination power of the recharge. Among them, the minimum protection power of the battery is the lowest power without damage to the battery. As the starting threshold of the recharge of the battery, it means that when the battery power is lower than the minimum protection power, the battery needs to be charged.
[0093] Step 304: Generate a target charging capacity of the battery according to the minimum protection capacity and the charging termination capacity.
[0094] In the embodiment of the present invention, the minimum protection power and the charging termination power are two thresholds for battery charging. One is the starting threshold for charging, which is set to P1, and the other is the termination threshold for charging, which is set to P2. At this time, the target charging power of the battery is P2-P1.
[0095] Step 305 , determining the number of intelligent charging times according to the available discharge capacity of the power battery and the target charging capacity of the storage battery.
[0096] In the embodiment of the present invention, after determining the available discharge capacity of the power battery and the target charging capacity of the storage battery, the number of intelligent charging times can be determined. It should be noted that this number of intelligent charging times is calculated in the current dormant state. If the subsequent vehicle is started and then goes into dormancy again, a new number of intelligent charging times needs to be recalculated.
[0097] A fourth embodiment of the present application relates to a power feeding warning device, Figure 4 is a block diagram of a power feeding warning device according to an exemplary embodiment. Figure 4 As shown, the following steps are included:

Through double reminders, the risk of power feeding of the vehicle is greatly reduced, and there is no need to wake up the vehicle regularly, which increases the power consumption of the low-voltage electrical appliances of the whole vehicle and saves electricity.
