[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, other existing embodiments obtained by ordinary technicians in the field without creative work should all fall within the scope of protection of the present application.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a schematic diagram of a control system for power battery charging provided according to an embodiment of the present application, such as Figure 1 As shown, the control system for power battery charging includes: a charging control network and a peripheral input control network, wherein the charging control network includes: a vehicle control unit (VCU) 1, a battery management system (BMS) 2, an engine controller (EMS) 3, a motor controller (MCU) 4, and a network harness (CAN1) 5 connected to the controller, and the peripheral input control network includes: a gateway (GW) 6, a vehicle remote terminal (T-BOX) 7, an air conditioning controller (AC) 8, a mobile phone application (APP) 9, an external temperature sensor 10, a signal line between the external temperature sensor and the AC 11, a GW connected to the VCU network harness (CAN2) 12, a GW connected to the AC network harness (CAN3) 13, and a GW connected to the T-BOX network harness (CAN4) 14. Figure 2 is a flow chart of a control method for power battery charging according to an embodiment of the present application, and the method is applied in Figure 1 In the control system of the power battery charging shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0032] Step S201, obtaining a target power value, a target temperature value and a target time value, wherein the target power value is used to indicate the current power of the power battery in the hybrid electric vehicle, the target temperature value is used to indicate the current temperature of the environment in which the power battery is located, and the target time value is used to indicate the sleep time of the hybrid electric vehicle.

[0033] For example, the external temperature sensor 10 transmits the signal to the AC through the signal line 11; after processing the temperature sensor signal, the AC obtains the ambient temperature TEMPat (the target temperature value mentioned above, that is, the current temperature of the environment in which the power battery is located), and the AC sends the signal TEMPat to the GW through CAN3; the GW sends the signal TEMPat to the VCU through CAN2. The BMS sends the power battery power SOCat (the target power value mentioned above, that is, the current power of the power battery) in real time through CAN1, and the VCU receives SOCat in real time. Then the sleep time of the hybrid vehicle is obtained. In addition, it should be noted that the above-mentioned external temperature sensor can also use other sensors to provide corresponding signals, and the above-mentioned path for obtaining the ambient temperature TEMPat and battery power SOCat signals can also change according to different network architectures.

[0034] Step S202 : determining whether to trigger a power replenishment request based on the target power value, the target temperature value and the target time value, wherein the power replenishment request is used to request power replenishment for the power battery.

[0035] For example, based on the current temperature of the power battery environment, the current power level and the sleep time of the hybrid vehicle, it is determined whether the vehicle remote terminal (T-BOX) sends a power battery recharging request to the user's mobile phone application (APP).

[0036] Step S203, after determining that the charging request is triggered, receiving a response result returned by the user to the charging request, and determining whether to charge the power battery according to the response result.

[0037] For example, if the vehicle-mounted remote terminal (T-BOX) sends a power battery recharging request to the user's mobile phone application (APP), it can receive the response result returned by the user for the recharging request, and then determine whether to recharge the power battery based on the result returned by the user.

[0038] Through the above steps S201 to S203, it is determined whether to trigger a power replenishment request based on the current power level of the power battery in the hybrid vehicle, the current temperature of the environment and the sleep time of the hybrid vehicle. After the power replenishment request is triggered, a response result returned by the user for the power replenishment request is received, and then it is determined whether to replenish the power battery based on the response result. Therefore, when the power level of the power battery in the hybrid vehicle is low and the temperature of the environment is low, a suitable time can be selected to charge the power battery so that the power battery will not be depleted, thereby achieving the effect of ensuring the normal use of the vehicle.

[0039] In order to accurately trigger the power replenishment request, in the power battery power replenishment control method provided in the embodiment of the present application, it is also possible to determine whether to trigger the power replenishment request through the following steps: determining a control flag based on a target power value and a target temperature value, wherein the control flag is used to control whether to recharge the power battery; and determining whether to trigger the power replenishment request based on the control flag and the target time value.

[0040] For example, the control flag may be a charging control flag. The charging control flag is determined to be 0 or 1 according to the current power of the power battery and the current temperature of the environment in which the power battery is located. Then, according to the determined charging control flag and the sleep time of the hybrid electric vehicle, it is determined whether the vehicle remote terminal (T-BOX) sends a power battery charging request to the user's mobile phone application (APP).

[0041] In summary, whether to trigger a power replenishment request can be determined quickly and accurately by obtaining the power replenishment control flag according to the current power level of the power battery and the current temperature of the environment and the sleep time of the hybrid electric vehicle.

[0042] In order to determine the control flag, in the control method for power battery charging provided in the embodiment of the present application, the control flag can also be determined by the following steps: if the target power value is less than the first preset threshold value, and the target temperature value is less than the second preset threshold value, then the control flag is determined to be the first preset flag; if the target power value is not less than the first preset threshold value, or the target temperature value is not less than the second preset threshold value, then the control flag is determined to be the second preset flag.

[0043] For example, when the ambient temperature TEMPat is lower than the threshold TEMPa and the SOCat is lower than the threshold SOCa, the supplementary power control flag additioncharge is set to 1; when the ambient temperature TEMPat is higher than the threshold TEMPa or the SOCat is higher than the threshold SOCa, the supplementary power control flag additioncharge is set to 0. The VCU sends the supplementary power control flag additioncharge to the GW in real time through CAN2, and the GW sends the signal additioncharge to the T-BOX through CAN4, and the T-BOX records and stores the additioncharge signal value.

[0044] Through the above solution, the power replenishment control flag can be accurately determined.

[0045] In order to accurately trigger the power replenishment request, in the power battery power replenishment control method provided in the embodiment of the present application, it can also be determined whether the power replenishment request is triggered through the following steps: if the control flag is the first preset flag or the second preset flag, and the target time value is greater than the third preset threshold, the power replenishment request is triggered; if the control flag is the first preset flag, and the target time value is not greater than the third preset threshold and greater than the fourth preset threshold, the power replenishment request is triggered, wherein the third preset threshold is greater than the fourth preset threshold.

[0046] For example, if the target time value is greater than the third preset threshold, it means that the hybrid vehicle is in a long-term parking state, rather than a short-term dormant state, and if the target time value is not greater than the third preset threshold and greater than the fourth preset threshold, it means that the hybrid vehicle is in a short-term dormant state, rather than a long-term parking state. Therefore, after the vehicle is in a dormant state, T-BOX starts timing, and when the time T is greater than the threshold Ta (the fourth preset threshold mentioned above), if the vehicle is not started and the additioncharge control flag value is 1, T-BOX sends a power battery addition request to the mobile phone APP. When the vehicle is parked for a long time, that is, when the time T is greater than the threshold Tb (the third preset threshold mentioned above), regardless of whether the additioncharge control flag value is 1 or 0 at this time, T-BOX will send a power battery addition request to the mobile phone APP.

[0047] Through the above solution, the power replenishment request can be accurately triggered according to the power replenishment control flag and the sleep time of the hybrid electric vehicle.

[0048] In order to accurately recharge the power battery, in the control method for recharging the power battery provided in the embodiment of the present application, it can also be determined through the following steps whether to recharge the power battery: if the response result indicates confirmation that the power battery is recharged, the power battery is recharged; if the response result indicates confirmation that the power battery is not recharged, the power battery is not recharged, and a first time value is obtained, wherein the first time value is used to indicate the time during which the hybrid vehicle is not started after the recharging request is triggered; if the response result indicates prohibition of recharging the power battery, the power battery is not recharged, and the recharging request is no longer triggered.

[0049] For example, after the user agrees, T-BOX wakes up GW through CAN4 and sends a request signal to allow power replenishment to GW, GW wakes up VCU through CAN2 and sends a request signal to allow power replenishment to VCU, VCU wakes up BMS, MCU, EMS through CAN1, and each controller coordinates the engine, generator, and power battery to charge. Moreover, when SOCat is higher than the threshold SOCb, power generation is stopped and the system enters a dormant state, and the above steps of obtaining the current power of the power battery and the current temperature of the environment in which the power battery is located, as well as the above steps of determining the control flag are simultaneously executed. If the user does not agree to power battery replenishment, the duration of the interval after the power replenishment request is sent but the vehicle is not started is determined. If a response result indicating that the user prohibits battery replenishment control is received, T-BOX will no longer send a power battery replenishment request to the mobile phone APP.

[0050] Through the above scheme, it is possible to accurately determine whether to recharge the power battery based on the user's response to the recharging request. At the same time, by actively and timely recharging, the battery aging problem caused by long-term parking of the vehicle can be reduced. That is, in the absence of dedicated charging equipment, the life of the power battery can be extended to avoid inconvenience to the user.

[0051] In order to ensure that the power battery is not depleted, in the power battery replenishment control method provided in the embodiment of the present application, after obtaining the first time value, the following steps can also be used to ensure that the power battery is not depleted: if the first time value is greater than the fifth preset threshold, the replenishment request is re-triggered; if the first time value is not greater than the fifth preset threshold, the current power value of the power battery and the current temperature value of the environment in which the power battery is located are re-obtained.

[0052] For example, if the user does not agree to recharge the power battery and does not start the vehicle after an interval of Tc (the fifth preset threshold value mentioned above), T-BOX continues to send a recharge request to the user. If the user starts the vehicle within Tc, the above steps of obtaining the current power of the power battery and the current temperature of the environment where the power battery is located are started again.

[0053] Through the above solution, it can be ensured that the power battery is not depleted, thereby extending the life of the power battery and avoiding inconvenience to the user.

[0054] In order to ensure the safety of hybrid vehicles, in the control method for power battery charging provided in the embodiment of the present application, the safety of hybrid vehicles can also be ensured by the following steps: during the process of charging the power battery, if a target fault is detected, a fault reminder message is triggered and the power battery charging is stopped.

[0055] For example, if a fault occurs during the charging of the power battery, the T-BOX notifies the user of the fault and stops charging the power battery. At the same time, the T-BOX will no longer send a charging request to the user before the next vehicle start.

[0056] Through the above solution, the safety of the hybrid vehicle can be guaranteed, and at the same time, the components in the hybrid vehicle can be prevented from being damaged.

[0057] Figure 3 is a flow chart of an optional power battery charging control method provided in an embodiment of the present application, such as Figure 3 As shown, the optional power battery charging control method includes the following steps: obtaining the ambient temperature TEMPat and the battery charge SOCat signal to determine whether charging is needed; when the ambient temperature TEMPat is lower than the threshold TEMPa and the SOCat is lower than the threshold SOCa, the charging control flag additioncharge is set to 1; when the ambient temperature TEMPat is higher than the threshold TEMPa or the SOCat is higher than the threshold SOCa, the charging control flag additioncharge is set to 0; when the time T is greater than the threshold Ta, if the vehicle is not started and the charging control flag additioncharge value is 1, T-BOX sends a power battery charging request to the mobile phone APP; if the vehicle is parked for a long time, When the time T is greater than the threshold Tb, T-BOX sends a power battery recharging request to the mobile phone APP; after receiving the user's consent to the recharging control request, the power battery is recharged. When the SOCat is higher than the threshold SOCb, the power generation is stopped and the system enters a sleep state; if a fault occurs during recharging, the recharging request will no longer be sent to the user before the next vehicle start; if the user does not agree to recharge the power battery and the vehicle is still not started after an interval of Tc, T-BOX continues to send recharging requests to the user; if the user starts the vehicle within Tc time, the system starts again from the steps of obtaining the ambient temperature TEMPat and the battery power SOCat signal; if the user prohibits battery recharging control, T-BOX will no longer send a power battery recharging request to the mobile phone APP.

[0058] In summary, the control method for power battery charging provided in the embodiment of the present application is applied in a hybrid electric vehicle, by obtaining a target power value, a target temperature value and a target time value, wherein the target power value is used to indicate the current power of the power battery in the hybrid electric vehicle, the target temperature value is used to indicate the current temperature of the environment in which the power battery is located, and the target time value is used to indicate the sleep time of the hybrid electric vehicle; based on the target power value, the target temperature value and the target time value, it is determined whether to trigger a charging request, wherein the charging request is used to request charging of the power battery; after determining that the charging request is triggered, a response result returned by the user for the charging request is received, and based on the response result, it is determined whether to charge the power battery, thereby solving the problem in the related art that when the power of the power battery in the hybrid electric vehicle is low and the temperature of the environment in which it is located is low, it is difficult to choose a suitable time to charge the power battery, resulting in power battery depletion and affecting the normal use of the vehicle. By determining whether to trigger a power replenishment request based on the current power level of the power battery in the hybrid vehicle, the current temperature of the environment, and the sleep time of the hybrid vehicle, and after the power replenishment request is triggered, receiving a response result returned by the user for the power replenishment request, and then determining whether to replenish the power battery based on the response result, when the power level of the power battery in the hybrid vehicle is low and the temperature of the environment in which it is located is low, a suitable time can be selected to charge the power battery so that the power battery will not be depleted, thereby achieving the effect of ensuring the normal use of the vehicle.

[0059] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
