[0034] This embodiment provides a method for replenishing energy for the above-mentioned vehicle. Figure 2 is a flow chart of a vehicle energy replenishment method according to one embodiment of the present invention. Figure 2 As shown, the process includes the following steps: Step S1: Collect the output power of the solar panel and the operating condition information of the vehicle, wherein the operating condition information includes at least one of the following: power-on status information and power-off status information. Step S2: When it is determined that the output power of the solar panel meets the power supply conditions, the solar panel charges the low-voltage battery, and compares the power of the low-voltage battery with the preset power value to obtain a comparison result. Step S3: Generate a control instruction set based on the comparison result and the operating condition information, and the control instruction set is used to control the low-voltage battery to execute an energy replenishment strategy, wherein the energy replenishment strategy includes at least one of the following: a strategy for powering low-voltage electrical equipment, a strategy for powering high-voltage electrical equipment, a strategy for charging the power battery, and a strategy for charging the vehicle-mounted battery.

[0035] In an embodiment of the present application, according to the working condition of the vehicle and the output power of the solar panel, the solar panel is controlled to charge the low-voltage battery, and then according to the power status of the low-voltage battery, the low-voltage battery is controlled to replenish energy for low-voltage electrical equipment, high-voltage electrical equipment, power batteries, and on-board batteries. The above-mentioned energy replenishment method and energy replenishment system enable the solar panel to provide electrical energy to the vehicle's power consumption system to the maximum extent, saving the vehicle's own energy consumption and improving the vehicle's driving range. At the same time, in the process of storing the electrical energy of the solar panel in the low-voltage battery, there is no need to wake up the control components of the vehicle, which further reduces the energy loss of the solar panel and enables the power of the solar panel to be maximized.

[0036] In step S3, a control instruction set is generated based on the comparison result and the operating condition information, including: when the vehicle is in a power-off state, determining whether the power level of the low-voltage battery is greater than or equal to the first calibration value. If so, a first target instruction in the control instruction set is generated, and the first target instruction is used to control the low-voltage battery to execute a first target strategy, wherein the first target strategy includes at least one of the following: a strategy for charging the vehicle battery, and a strategy for charging the power battery. The first calibration value is freely set according to actual needs, and generally, the first target instruction in the control instruction set is generated when the power level of the low-voltage battery reaches a full state or is close to a full state.

[0037] In the above steps, the vehicle is in a power-off state, and the vehicle's low-voltage electrical equipment and high-voltage electrical equipment have no power demand. When the low-voltage battery is fully charged or nearly fully charged, in order to fully utilize the electrical energy in the solar panels, the electrical energy is further stored in the vehicle battery and the power battery through the low-voltage battery.

[0038] In step S3, a control instruction set is generated based on the comparison result and the working condition information, including: when it is determined that the vehicle is in a power-off state and the power of the low-voltage battery is greater than or equal to the first calibration value, it is determined whether the power of the vehicle-mounted battery is greater than or equal to the second calibration value. If so, a second target instruction in the control instruction set is generated, and the second target instruction is used to control the low-voltage battery to execute a strategy for charging the power battery. Among them, the second calibration value is freely set according to actual needs. Generally, when the power of the vehicle-mounted battery reaches a full state, the second target instruction in the control instruction set is generated.

[0039] In the above steps, the low-voltage battery and the vehicle battery are not the same battery. When the vehicle is powered off, the vehicle's low-voltage and high-voltage electrical equipment have no power demand. When charging the power battery, some controllers need to be woken up, which will cause a certain amount of low-voltage power loss. When charging the vehicle battery, there is no need to wake up the controller, and there is basically no low-voltage power loss. After the vehicle battery is fully charged, the power battery is charged according to the power status of the low-voltage battery. When the power battery is not fully charged or not charged, the power of the solar panel is maximized.

[0040] In step S3, a control instruction set is generated based on the comparison result and the operating condition information, including: when the vehicle is in the powered-on state, judging whether the power of the low-voltage battery is greater than or equal to the third calibration value; if so, judging whether the low-voltage electrical equipment is in the working state. If so, a third target instruction in the control instruction set is generated, and the third target instruction is used to control the low-voltage battery to execute the second target strategy, wherein the second target strategy includes at least one of the following: a strategy for supplying power to the low-voltage electrical equipment, and a strategy for charging the vehicle-mounted battery. Among them, the third calibration value is freely set according to actual needs, and generally the third target instruction in the control instruction set is generated when the power of the low-voltage battery reaches a full state or is close to a full state.

[0041] In the above steps, the vehicle is powered on, and both the low-voltage and high-voltage electrical equipment of the vehicle have power requirements. When the low-voltage battery supplies power to the low-voltage electrical equipment, there is no need for voltage transformation, no voltage transformation loss, and the power in the solar panel can be maximized. In the process of supplying power to the low-voltage electrical equipment, the remaining power is stored in the vehicle battery.

[0042] In step S3, a control instruction set is generated based on the comparison result and the operating condition information, including: when it is determined that the vehicle is in a powered-on state and the power of the low-voltage battery is greater than or equal to the third calibration value, whether the power of the vehicle-mounted battery is greater than or equal to the fourth calibration value. If yes, determine whether the high-voltage electrical equipment is in working condition. If not, generate the fourth target instruction in the control instruction set, and the fourth target instruction is used to control the low-voltage battery to execute the strategy of charging the power battery. Among them, the fourth calibration value is freely set according to actual needs. Generally, when the power of the vehicle-mounted battery reaches a full state, the fourth target instruction in the control instruction set is generated.

[0043] In the above steps, the vehicle is powered on, and the low-voltage battery first supplies power to the low-voltage electrical equipment and the on-board battery. When the on-board battery is fully charged, it means that there is still residual power in the solar panel. If the high-voltage electrical equipment is not in operation, the residual power in the solar panel is stored in the power battery through the low-voltage battery.

[0044] In step S3, a control instruction set is generated based on the comparison result and the working condition information, including: when it is determined that the vehicle is in a powered-on state and the power of the low-voltage battery is greater than or equal to the third calibration value, it is determined whether the power of the vehicle-mounted battery is greater than or equal to the fourth calibration value. If so, it is determined whether the high-voltage electrical equipment is in a working state. If so, a fifth target instruction in the control instruction set is generated, and the fifth target instruction is used to control the low-voltage battery to execute a strategy for supplying power to the high-voltage electrical equipment.

[0045] In the above steps, the vehicle is powered on, and the low-voltage battery first supplies power to the low-voltage electrical equipment and the on-board battery. When the on-board battery is fully charged, it means that there is still residual power in the solar panel. If the high-voltage electrical equipment is in operation, the residual power in the solar panel supplies power to the high-voltage electrical equipment through the low-voltage battery. Since some controllers need to be awakened to charge the power battery, there is a low-voltage power loss.

[0046] This embodiment provides a vehicle energy replenishment system. Figure 3 is a schematic diagram of the structure of an energy replenishment system according to one optional embodiment of the present invention, such as Figure 3 As shown, the energy replenishment system includes: a solar panel, a low-voltage battery, a solar controller and a low-voltage control unit.
