In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
First, a charge and discharge management system suitable for the present application is described. Fig. 1 is a schematic structural diagram of a charge and discharge management system according to an embodiment of the present application. The charge/discharge management system 10 shown in fig. 1 includes: charging system module 200, discharging system module 300, and thermal management module 400. Wherein, the liquid crystal display device comprises a liquid crystal display device,
the charging system module 200 is used for performing charging management on a vehicle. Specifically, for example, a charge-discharge management system (which may also be referred to as a vehicle reservation energy management system) collects vehicle management information of a vehicle, which is information related to the vehicle, which may include, but is not limited to, any one or a combination of more of the following: the current remaining capacity of the vehicle (e.g., a State of Charge (SOC) value for reflecting the remaining capacity of the battery), the battery temperature, the passenger compartment temperature, grid electricity rate information, and user vehicle demands (e.g., reservation vehicle information), etc. The charging system module 200 may determine that the Vehicle management information meets the preset charging condition, and if the Vehicle management information meets the preset charging condition, perform charging processing from the corresponding power Grid to the Vehicle (G2V).

Specific operation of the charging system module 200, the discharging system module 300, and the thermal management module 400 according to the embodiments of the present application will be described in detail below, and will not be described in detail herein.
Secondly, the charge and discharge management method provided by the application is introduced. Fig. 2 is a schematic flow chart of a charge and discharge management method based on internet of vehicles according to an embodiment of the present application. The method as shown in fig. 2 comprises the following implementation steps:
and S201, after detecting that the vehicle is inserted into the charging pile, acquiring vehicle management information, wherein the vehicle management information at least comprises the current residual electric quantity of the vehicle.
According to the application, after the vehicle parking is detected and the charging pile is inserted, the function of a charging and discharging management system of the vehicle can be started, and then the charging and discharging management system is utilized to collect vehicle management information. The vehicle management information includes, but is not limited to, at least one of: the current remaining capacity of the vehicle, the battery temperature, the passenger cabin temperature, the grid electricity price information, the reserved vehicle information or other vehicle information and the like.
Alternatively, the reserved vehicle information may be reserved vehicle use requirement information that is filled by a user (vehicle owner) through a remote application APP, which may specifically include, but is not limited to, the following information: a vehicle start time, a vehicle end time, a predicted vehicle duration, or other information, etc.
And S202, if the vehicle management information meets a preset discharging condition, discharging the vehicle to a power grid V2G.
The application can judge whether the vehicle management information meets the preset discharge condition of the vehicle, and if so, the vehicle is subjected to V2G discharge treatment; if not, the method can continue to judge whether the preset charging condition is met or directly end the process. The preset discharging condition is a condition which is configured by a system or a user in a self-defining way and is used for judging the discharging of the vehicle.
In one embodiment, the preset discharge condition is: the current residual electric quantity of the vehicle is larger than or equal to a first preset electric quantity (the residual electric quantity of the vehicle is more or sufficient), the distance between the vehicle starting time indicated by the reserved vehicle information and the current time of the system is longer than or equal to a first preset duration (namely, the current distance is longer than the current distance, the vehicle is not used for emergency), and the current electricity price indicated by the grid electricity price information is smaller than or equal to a first preset electricity price (the current electricity price is lower).
The first preset electric quantity, the first preset duration and the first preset electricity price are all set by a system in a self-defined mode or experience values set by a user according to experience, for example, the first preset electric quantity is 50% of the full electric quantity of a vehicle, the first preset duration is 4 hours, and the first preset electricity price is 0.8 angle/degree.
In other words, when the vehicle management information is judged to simultaneously meet three sub-conditions in the preset discharging conditions, the V2G discharging function can be started, and the electric quantity of the vehicle battery is transmitted to the power grid through the charging pile to be discharged, so that a high electric charge spread is earned, and the maximization of benefits is realized.
And S203, if the vehicle management information meets the preset charging condition, carrying out charging processing from the power grid to the vehicle G2V on the vehicle. Wherein the preset charging condition and the preset discharging condition are both preset conditions related to the vehicle management information.
The application can judge whether the vehicle management information meets the preset charging condition of the vehicle, and if so, G2V charging treatment is carried out on the vehicle; if not, the method can continue to judge whether the preset discharge condition is met or directly end the process. The preset charging conditions are conditions which are configured by a system or a user in a user-defined mode and used for judging vehicle charging.
In one embodiment, the preset charging conditions are: the current remaining power of the vehicle is less than or equal to a second preset power (the remaining power of the vehicle is less), and the current electricity price indicated by the grid electricity price information is less than or equal to a second preset electricity price (the current electricity price is lower). That is, the current remaining power of the vehicle is smaller, and the current electricity price in the power grid is lower, so that the G2V charging process can be allowed to be performed on the vehicle, so as to save or reduce the charging cost of the vehicle. The second preset electric quantity and the second preset electric price are set by a system or a user in a self-defining way, and the second preset electric quantity and the first preset electric quantity can be the same or different; the second preset electricity price and the first preset electricity price may be the same or different, and the application is not limited.
In yet another specific embodiment, the preset charging condition is: the current remaining power of the vehicle is smaller than or equal to a second preset power (the remaining power of the vehicle is smaller), and the distance duration between the vehicle starting time indicated by the reserved vehicle information and the current time of the system is smaller than or equal to the full charge duration (the current distance duration is too short for the vehicle to take an urgent vehicle). When the preset charging condition is judged to be met, G2V charging treatment is needed to be carried out on the vehicle immediately no matter whether the current electricity price in the power grid is high or low, so that user experience of a subsequent vehicle is ensured, and influence on the cruising ability of the vehicle is reduced.
The electric quantity full-charge duration is a duration which is calculated according to the current residual electric quantity of the vehicle and is required to be spent for fully charging the vehicle battery. That is, the present application may calculate the charge full duration of the vehicle battery according to the current remaining charge of the vehicle, and the specific calculation is as shown in the following formula (1):
wherein T is c For a charge full period (also referred to as charge remaining period), A is the current remaining charge or capacity of the vehicle, I is the current charge current, I m A is a pre-stored current which is close to and smaller than I and is pre-stored 1 And a 2 Is constant and a 1 And a 2 The sum is 1.
In an alternative embodiment, the current remaining capacity of the vehicle is smaller than or equal to a second preset capacity (the remaining capacity of the vehicle is smaller), at this time, if it is determined that the distance between the vehicle start time indicated by the reserved vehicle information and the current time of the system is longer than the full charge time (the current distance is longer than the time of the vehicle and no urgent vehicle is involved), and the current electricity price indicated by the grid electricity price information is greater than or equal to a second preset price (the current electricity price is too high), that is, the vehicle management information meets the preset maintenance condition, the present application can maintain the current state of the vehicle, prohibit the charging or discharging process of the vehicle, that is, at this time, perform the charging-free and discharging process of the vehicle.
Further optionally, according to the grid electricity price information, the vehicle starting time indicated by the reserved vehicle information and the full charge duration, a proper optimal charging time is selected before the vehicle starting time to perform G2V charging treatment on the vehicle so as not to influence the continuous voyage use of the following vehicle.
In an optional embodiment, when the distance duration between the vehicle start time indicated by the reserved vehicle information and the current time of the system is detected to be smaller than or equal to the second preset duration (namely, the current distance duration is too short), the thermal management system of the vehicle can be started, and the charging pile is used for supplying power to the vehicle to perform corresponding temperature control processing. The second preset duration is set by a system or a user in a self-defining manner, and is smaller than the first preset duration, for example, the second preset duration is 30 minutes (min) or the like.
In particular, after the vehicle starts the thermal management system, temperature information of the battery temperature and/or the passenger cabin temperature can be collected, and then the temperatures can be controlled. For example, when it is determined that the battery temperature and/or the passenger compartment temperature is greater than or equal to the corresponding first preset temperature (e.g., 25 ℃) and the temperature is too high, the battery temperature and/or the passenger compartment temperature may be subjected to a cooling process, such as controlling the operation of an electric compressor, reducing the battery temperature and/or the passenger compartment temperature to an optimal suitable temperature by using cooling water in the engine, and the like. On the contrary, when the battery temperature and/or the passenger compartment temperature are/is determined to be less than or equal to the corresponding second preset temperature (for example, 0 ℃) and the indicated temperature is too low, the battery temperature and/or the passenger compartment temperature can be subjected to temperature raising treatment, for example, heating by using a vehicle TTC thermistor or the like to enable the battery temperature and/or the passenger compartment temperature to be heated to be within an optimal temperature range or the like.
The charging pile has the functions of supporting linkage, reservation and V2G discharging, and can respond to the charging and discharging use requirements of vehicles at any time. Steps S202 and S203 according to the present application do not specify the execution sequence, and for example, step S203 may be executed first and then step S202 may be executed, which is not limited to the present application.
By implementing the application, the electric off-peak charge can be intelligently carried out on the vehicle based on the collected information such as the current residual electric quantity of the vehicle, the temperature of the battery, the temperature of the passenger cabin, the electric grid electricity price information or the reserved vehicle information, so that the vehicle charge cost is minimized, and the peak wave discharge is realized to maximize the electric charge income. The battery and the passenger cabin are heated or cooled by the electric quantity of the charging pile before the running, so that the influence of the whole vehicle on endurance is reduced, and the performance and the comfort of the vehicle can be improved. Meanwhile, the problems that in the prior art, the charging peak period is easy to cause, the power grid resources are not reasonably utilized, the reverse power supply of the vehicle is not considered and the like are solved.
