[0031] In order to make the purposes, characteristics and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] Figure 1 An implementation flow diagram of a vehicle charging method according to an embodiment of the present application is shown;

[0033] Referring to Figure 1 According to a first aspect of an embodiment of the present application, a vehicle charging method is provided, the method comprising: operation 101, obtaining a charging request corresponding to a specified vehicle; operation 102, determining a safe charging current according to a battery safe temperature of the specified vehicle; operation 103, controlling a multi-mode power supply group to perform charging processing on the specified vehicle at the safe charging current; wherein the multi-mode power supply group comprises a first charging device and a second charging device.

[0034] A vehicle charging method provided by an embodiment of the present application takes the battery safe temperature corresponding to the specified vehicle as the basis to control the first charging device and the second charging device to perform charging processing on the specified vehicle according to the battery safe temperature, and improves the charging power through the double charging mode of the first charging device and the second charging device, thereby improving the charging efficiency of the vehicle. The first charging device and the second charging device can come from the same or different energy sources, providing a channel for the comprehensive utilization of multiple energy sources.

[0035] In operation 101 of the method, the method can be applied to a vehicle charging system, and the charging system is used to control the first charging device and the second charging device. When a user has a charging demand for a specified vehicle, the charging port of the specified vehicle is connected to the charging port of the charging system, and the charging system obtains a charging request corresponding to the specified vehicle through the operation instruction of the user. According to the settings, the specific user operations include but are not limited to card swiping, two-dimensional code scanning, account login, etc.

[0036] In operation 102 of the method, the charging system can determine the battery safe temperature corresponding to the specified vehicle according to the user request to determine the safe charging current. It can be understood that different vehicles will be configured with different batteries, and correspondingly, according to the characteristics of different batteries, the corresponding battery safe temperature will also be different during the charging process. Based on this, the method can determine the safe charging current according to the battery safe temperature, so as to control the charging current not to exceed the safe charging temperature, and ensure the stability during the charging process.

[0037] In one implementation scenario, the charging request of the method can carry the battery safety temperature, so that the charging system determines the battery safety temperature according to the charging request, and then determines the safe charging current; in another implementation scenario, the charging request of the method can carry the battery model corresponding to the specified vehicle, and correspondingly, the storage module of the charging system stores a data table corresponding to the battery model and the battery safety temperature, and the charging pile can find the battery safety temperature corresponding to the specified vehicle according to the data table, and then determine the charging safety temperature. The storage module can be a local storage module or a cloud storage module. When the storage module is a cloud storage module, the method updates the data table in real time through the cloud, and timely inputs the new battery model, battery version and corresponding safe charging current on the market, so that the charging system can accurately determine the battery safety temperature corresponding to the specified vehicle. During the charging process, the battery real-time temperature does not exceed the charging safety temperature during the charging of the specified vehicle by the safe charging current, so as to ensure the safety of the charging process.

[0038] In operation 103 of the method, according to the determined safe charging current, the multi-mode power supply group is controlled, specifically, the safe charging current can be distributed to multiple charging devices, and the specified vehicle is charged simultaneously through the multiple charging devices. The multi-mode power supply group at least includes a first charging device and a second charging device, that is, the charging device of the method can be two or more. According to the need, the method can distribute the safe charging current by current division, proportional division according to the remaining capacity of the charging device, setting charging priority, etc.

[0039] In one implementation, operation 101, determining the safe charging current according to the battery safety temperature of the specified vehicle, includes: then, determining the battery real-time temperature of the specified vehicle; determining the safe charging current according to the battery real-time temperature and the battery safety temperature.

[0040] The method can set temperature sensors at the charging port of the charging system and the charging port of the specified vehicle, and during the charging process, the battery real-time temperature of the specified vehicle is determined by calculating the temperature of the charging port. In another implementation scenario, the method provides a temperature sensor for detecting the battery temperature in the specified vehicle, and during the charging process, the charging system is communicatively connected with the battery management system of the specified vehicle to receive the battery real-time temperature from the specified vehicle, so as to achieve the purpose of determining the safe charging current according to the battery real-time temperature and the battery safety temperature. Specifically, the battery safety temperature of the method is used to represent the highest temperature that can be reached under the safe state of the battery, and the battery real-time temperature refers to the current temperature of the battery. By the battery real-time temperature and the battery safety temperature, the safety difference of the battery reaching the battery safety temperature can be known, and then the corresponding safe charging current is determined by using the safety difference.

[0041] In an embodiment, operation 101, determining the safe charging current according to the battery safe temperature of the specified vehicle, comprises: firstly, determining the current power of the specified vehicle; then, determining the target power according to the current power; and then, determining the safe charging current according to the target power and the battery safe temperature.

[0042] It can be understood that, during the charging process of the battery, the temperature of the battery will rise with the charging current. Generally, the greater the current, the faster the temperature rises. The relationship between the charging current and the temperature rising rate can also be stored in the storage module of the charging system through a data table formed by the relationship between the charging current and the temperature rising rate.

[0043] The method can determine the safe difference according to the real-time temperature of the battery and the safe charging current, and determine the charging power required for charging according to the current power and the target power of the specified vehicle. By using the safe difference and the charging power, the temperature rising rate that the battery can withstand when charging from the current power to the target charging power can be calculated, and then the safe charging current can be determined through the data table of the relationship between the charging current and the temperature rising rate.

[0044] In an embodiment, operation 103, controlling the multi-mode power supply group to charge the specified vehicle with the safe charging current, comprises: firstly, distributing the safe charging current to determine the first charging current corresponding to the first charging device and the second charging current corresponding to the second charging device; then, controlling the first charging device to charge the specified vehicle with the first charging current; and controlling the second charging device to charge the specified vehicle with the second charging current.

[0045] In a specific implementation scenario, the current distribution manner of the method can be 1:1 distribution of the current according to the number of charging devices. For example, when the safe charging current is a, the charging current of the first charging device is a / 2 and the charging current of the second charging device is a / 2 in the case of two charging devices. The first charging device and the second charging device are controlled to charge the specified vehicle with a / 2 current respectively.

[0046] In an embodiment, distributing the safe charging current to determine the first charging current corresponding to the first charging device and the second charging current corresponding to the second charging device, comprises: firstly, determining the first energy storage power of the first charging device; then, determining the first charging power corresponding to the first charging device and the second charging power corresponding to the second charging device according to the target power and the first energy storage power; and then, determining the first charging current corresponding to the first charging device and the second charging current corresponding to the second charging device according to the safe charging current, the first charging power and the second charging power.

[0047] In another implementation scenario, the current distribution manner of the method can also proportionally distribute the current according to the energy storage amount of the charging device, wherein the energy storage amount refers to the remaining amount of the charging device. For example, the remaining amount of the first charging device is 2d, the remaining amount of the second charging device is d, and the design maximum storage amount of the first charging device and the second charging device is the same. When the safe charging current is determined to be a, the charging current allocated to the first charging device is 2a / 3, and the charging current of the second charging device is a / 3.

[0048] The method can also use other ways to distribute the safe charging current. It can be understood that in the above operation, the first charging device is controlled to charge the specified vehicle at the first charging current, and the second charging device is controlled to charge the specified vehicle at the second charging current, which are simultaneous charging operations.

[0049] In an implementation manner, the safe charging current is distributed to determine the first charging current corresponding to the first charging device and the second charging current corresponding to the second charging device, which includes: distributing the safe charging current according to a preset distribution ratio to determine the first charging current corresponding to the first charging device and the second charging current corresponding to the second charging device.

[0050] In another implementation scenario, the current distribution manner of the method can be preset according to the actual situation of the charging device for each charging device. For example, there are two charging devices, the design maximum storage amount of the first charging device is 2b, and the maximum current it can output is 2c, the design maximum storage amount of the second charging device is b, and the maximum current it can output is c, and the method can preset the charging current ratio of the first charging device and the second charging device to be 2:1. When the safe charging current is determined to be a, the charging current allocated to the first charging device is 2a / 3, and the charging current of the second charging device is a / 3.

[0051] In an implementation manner, after the operation 103 of controlling the multi-mode power supply group to charge the specified vehicle at the safe charging current, the method further includes: first, determining the corresponding temperature change rate according to the real-time temperature of the battery of the specified vehicle; then, when the temperature change rate exceeds the temperature rate threshold, controlling the first charging device and / or the second charging device to stop charging the specified vehicle.

[0052] In the process of controlling the multi-mode power supply group to charge the specified vehicle at the safe charging current, the method also monitors the real-time temperature of the battery of the specified vehicle in real time through the temperature sensor, and determines the corresponding temperature change rate by calculation. When the temperature change rate exceeds the temperature rate threshold, the first charging device and / or the second charging device is controlled to stop charging the specified vehicle to ensure charging safety.

[0053] The temperature rate threshold value can be a preset threshold value, or can be determined according to the temperature rate that the battery can withstand when charging from the current charge to the target charge. Specifically, the temperature rate that the battery can withstand when charging from the current charge to the target charge can be determined as the temperature rate threshold value. In this way, the temperature rate threshold value can be flexibly adjusted according to the battery characteristics and the battery temperature, and the charging safety is further ensured.

[0054] It should be noted that in another implementation, the method can directly monitor the real-time temperature of the battery of the specified vehicle, compare the real-time temperature of the battery with the battery safety temperature, and stop charging the specified vehicle when the real-time temperature of the battery exceeds the battery safety temperature.

[0055] In another implementation, the method can determine the corresponding battery temperature threshold value by integrating the temperature rate of the battery and the battery safety temperature, and stop charging the specified vehicle when the real-time temperature of the battery of the specified vehicle exceeds the battery temperature threshold value.

[0056] Specifically, the method can determine the charging device to stop charging according to the rate exceeding amount of the real-time temperature rate exceeding the temperature rate threshold value. For example, if the rate exceeding amount does not exceed a first value of the temperature rate threshold value, the first charging device or the second charging device can be controlled to stop charging the specified vehicle, wherein the first charging device or the second charging device can be preset in advance. If the rate exceeding amount does not exceed a second value of the temperature rate threshold value, the first charging device and the second charging device can be controlled to stop charging the specified vehicle. The first value is less than the second value, for example, the first value can be 5%, and the second value can be 10%.

[0057] In an implementation, the first charging device is a solar charging device. After obtaining the charging request corresponding to the specified vehicle in operation 101, the method further includes: if the solar charging device is in a charging mode, switching the solar charging device to a discharging mode.

[0058] The solar charging device is a device that converts solar energy into electrical energy. After converting solar energy into electrical energy, the electrical energy is stored in a storage battery. The storage battery can be any form of storage device, mainly composed of a solar light pool, a storage battery, and a voltage regulating element. It has the characteristics of green environmental protection. By switching the solar charging device from the charging mode to the discharging mode, the charging demand of the specified vehicle by the solar charging device is realized.

[0059] In an implementation, after the multi-mode power supply group completes charging the specified vehicle, the method further includes: first, switching the solar charging device to a charging mode; then, controlling the second charging device to charge the solar charging device; and then, controlling the solar panel to charge the solar charging device.

[0060] Correspondingly, after completing charging the specified vehicle, the method uses the second charging device and the solar panel to simultaneously charge the solar charging device, so as to ensure that the solar charging device can quickly store electricity and meet the charging demand of the next user. The second charging device can be connected to the power grid, so as to obtain power supply from the power grid.

[0061] To facilitate further understanding of the above implementation, a specific implementation scenario is provided below for description.

[0062] The vehicle charging method provided by the embodiment of the application is applied to a charging system, and the charging system includes a solar charger and a charging pile connected to a power grid. The solar charger includes a solar panel, the solar panel is configured to collect solar energy, the solar energy is converted into electric energy by the solar charger, and the electric energy is input into an energy storage battery. An interface is arranged on the energy storage battery and connected to a vehicle battery system, and the energy storage battery is configured to discharge electric energy to the vehicle.

[0063] When a user needs to perform fast charging, the battery charging port is connected to the charging interface of the energy storage battery, a card swiping operation is performed on the charging pile, and a double charging mode is selected.

[0064] After the charging system receives a charging request corresponding to the double charging mode, it is determined whether the charging interface and the battery are connected to correct positions. If it is determined that the charging interface and the battery are connected to correct positions, the double charging mode is entered.

[0065] Then, the charging system switches the solar charger from a charging mode to a discharging mode, collects a current electric quantity value in the energy storage battery through a communication connection with the solar charger, and determines a real-time battery temperature, a current battery electric quantity and a battery safety temperature of the vehicle battery through communication with a battery management system (BMS).

[0066] Subsequently, the charging system determines a total electric quantity required for charging, a corresponding total charging current and a temperature rate threshold value according to the real-time battery temperature, the current battery electric quantity and the battery safety temperature.

[0067] Then, the charging system allocates the total charging current to the charging pile and the energy storage battery according to the current electric quantity value of the energy storage battery, and controls the charging pile and the energy storage battery to charge the battery according to the allocated charging current.

[0068] During the charging process, the charging system monitors the real-time temperature of the vehicle-mounted battery through the BMS, determines the real-time heating rate of the vehicle-mounted battery according to the real-time temperature of the battery, and controls the charging pile and / or the energy storage battery to stop charging the battery when the real-time heating rate exceeds the temperature rate threshold.

[0069] After the charging is completed, the charging system switches the solar charger from the discharging mode to the charging mode, so that the solar panel continues to absorb solar energy and converts the solar energy into electrical energy and stores it in the energy storage battery. When the remaining power of the power grid is large and the charging pile is not connected to the vehicle, the charging pile can continue to charge the energy storage battery to store the excess power. In addition, according to the user's demand, the mode switching between single charging and double charging can also be selected; for example, in the case of large pressure of the power grid, the connection between the charging pile and the energy storage battery is disconnected, and the charging is completed by the energy storage battery. The method provided in the application combines solar charging and double charging mode, and can flexibly switch the working mode under various working conditions to improve the charging efficiency.
