step S401: first camping related information and battery reservation information input by a first user are received.

The first camping related information comprises the arrival time, the ending time and the activity place of the first user, the battery reservation information comprises the number and the model number of target batteries, and the target batteries are batteries of the electric trolley reserved for use by the first user in a target time period.

In an actual scene, if one electric trolley is reserved and rented by a plurality of users, and the reserved and rented time period of each user is different, the first user rents the electric trolley for the users after the electric trolley is used by the plurality of users. In the embodiment of the application, the first user is a user who uses the electric trolley in a first batch in a camping peak period.

The target time period is the first time period for reserving to use the electric trolley.

The first camping related information and the battery reservation information may be sent to a cloud server after the first user accesses an APP or a webpage through a mobile terminal and fills in information content.

The battery reservation information may represent, to some extent, the number of other camping appliances carried by the first user, and in brief, the greater the number of target batteries in the battery reservation information, the greater the battery capacity, the higher the power consumption requirement that the user may have during camping, and the more likely the other power consuming appliances are carried.

Step S402: and estimating the first electric quantity of the first user in the target time period according to the first camping related information.

The first electricity quantity comprises the electricity consumption of the electric trolley in the target time period.

The target time period may be determined according to the first camping related information, if the time for the first user to reach the campsite is Saturday 8:00, the ending time, namely ending camping activities, leaving campsite for 18:00, the target time period is Saturday 8:00-18:00.

Optionally, the electricity consumption of the electric trolley in the target time period is the electricity required by the electric trolley to normally drive and run in the target time period.

Because the electric trolley has the charge and discharge functions, the first electric quantity of the first user in the target time period has other electric quantities for electric appliances electrically connected with the socket of the electric trolley besides the normal driving running electric quantity of the electric trolley in the target time period, so that in order to accurately estimate the first electric quantity of the first user in the target time period, in an alternative implementation mode, firstly, weather information of an activity place in the first camping related information is determined; the weather information can be determined by weather information issued by an weather table;

Further, determining a first additional power consumption according to the weather information, wherein the first additional power consumption is used for representing the power quantity possibly consumed by the first user for driving by using the electric trolley during camping;

specifically, the weather information includes a windy weather, a snowy weather, a sunny weather, and the like, wherein the windy weather corresponds to a wind speed level, the snowy weather includes a corresponding rainfall level and a snowfall level, and it is noted that, because the electric trolley is mainly used for supplying power in a camp on the windy weather and the snowy weather and is rarely used for transporting goods on the windy weather and the snowy weather, the first additional power consumption is lower on the windy weather and the rainy weather, and the first additional power consumption is higher on the sunny weather;

Therefore, according to the statistics of the electric quantity consumed by the electric trolley due to driving running under different days acquired by the cloud server, determining first additional electric consumption corresponding to different weather information respectively, wherein the first additional electric consumption can be an average value of the electric quantity consumed by the electric trolley under the same weather, or can be an average value of the electric quantity consumed by the electric trolley under the same weather and the same corresponding level, for example, if the weather information of the camping place in the target time period is six-level high-wind weather, determining an average value of the electric quantity consumed by the electric trolley under the history of the high-wind weather of the six-level air, and taking the average value as the estimated first additional electric consumption of the reserved electric trolley of the first user;

secondly, determining second extra power consumption according to the wattage and the number of other electric appliances carried by camping input by the first user;

Optionally, the other electrical appliances comprise a desk lamp, an electric gas stove, a charger, a flashlight, a mosquito-repellent lamp and a mobile air conditioner;

Specifically, according to the time length of using the other electric appliances by the tourists in different time periods in different seasons, the time length of using the other electric appliances by the first user can be estimated, because in camping activities in different seasons, the electric appliances carried by the user can be different in different time periods in the day, but the electric appliances carried by the user can be different in the same season or the same time period in the day, for example, mosquito-repellent lamps, fans or mobile air conditioners are generally carried by the tourists camping in summer, table lamps or flashlights are generally carried by the tourists camping at night, and therefore, the time length of using the other electric appliances by the first user can be estimated according to the time length of using the other electric appliances carried by the other tourists in a certain time period in a certain season, and further, the second additional power consumption amount and the power consumption amount carried by camping input by the first user and the time length of using the other electric appliances are determined;

Finally, estimating the first electric quantity of the first user in the target time period according to the first additional electric quantity and the second additional electric quantity, and optionally, the first electric quantity of the first user in the target time period is the sum of the first additional electric quantity and the second additional electric quantity.

Step S403: it is determined that there is a second user reserving use of the electric dolly for another period of time after the target period of time.

The second user rents the first user for the next batch of users using the electric trolley after using the electric trolley, and the target time period for renting the first user for the electric trolley is Saturday 8:00-18:00, the second user reserves the time of using the electric trolley as other time periods after the target time period, and the other time periods are sunday 8:00-18:00, during which no other users lease the electric trolley, determining that the second user reserves to use the electric trolley in other time periods after the target time period.

The definition of the first user and the second user is determined according to the sequence of the time period of the same electric trolley, and the electric trolley is assumed to be reserved for use by the second user on day 8:00-18: and 00, if other users rent the electric trolley, the second user and the other users can reuse the method after the first user uses the electric trolley, and in the process, the second user is the first user, and the other users are new second users.

Step S404: and estimating second electricity consumption of the second user in the other time periods according to the second camping related information input by the second user.

The process of estimating the second electricity consumption of the second user in the other time period is similar to the process of estimating the first electricity consumption of the first user in the target time period, and the electricity consumption of the electric trolley in the other time period can be determined through weather information of an active place in the second camping related information, and the electricity consumption of other electric appliances carried by camping input by the second user is determined through the wattage and the number of the other electric appliances; and finally, estimating the second electricity consumption of the second user in other time periods according to the electricity consumption of the electric trolley for driving in other time periods and the electricity consumption of other electric appliances.

Step S405: generating an energy supplementing strategy according to the battery reservation information, the first camping related information, the second camping related information, the first electric quantity of the first user in the target time period and the second electric quantity of the second user in the other time periods so as to meet the electric demands of the first user in the target time period and the second user in the other time periods.

Because the photovoltaic energy storage system is arranged in the camping camp in the embodiment of the application, the accurate grasp of the charging time is needed for charging the electric trolley through the photovoltaic energy storage system, the normal use of the electric trolley reserved by the first user and the second user is avoided, and the accurate control of the charging quantity is needed, so that the problem of energy waste caused by excessive charging is avoided, when the first user and the second user rent and rent the electric trolley again without other users, namely, when the camping peak period is ended, the electric energy of the battery is naturally lost during the period waiting for the beginning of the next camping peak period, and in an optional implementation process, the specific implementation process is as follows:

if the current electric quantity of the target battery can exceed the sum of the first electric quantity of the first user in the target time period and the second electric quantity of the second user in the other time periods, determining whether the current electric quantity of the target battery can meet the electricity requirements of the first user and the second user;

Under the condition that the target battery can only meet the electricity demand of the first user, determining first energy supplementing time according to the arrival time in the first camping related information, wherein the first energy supplementing time is the time from the current time point to the time point when the first user arrives at the campsite and meets the electricity generation condition of a photovoltaic energy storage system; the first energy replenishment time is illustrated below, if the first user arrives at the campsite for Saturday 8:00, the ending time, namely ending camping activities, leaving campsite for 18:00, current time point is friday morning 8:00, friday morning 8:00 to Saturday morning 8:00 is the time that the target battery can be charged;

The application needs to charge the target battery through the photovoltaic energy storage system, but if the electric energy stored by the storage battery module in the photovoltaic energy storage system is not needed, the electric energy directly generated by the photovoltaic power generation module in the photovoltaic energy storage system is needed to charge, so the time from the current time point to the time point when the first user arrives at the campsite and meeting the power generation condition of the photovoltaic energy storage system is determined as the first energy supplementing time, during which the target battery, namely the electric trolley, can be charged through the photovoltaic power generation module of the photovoltaic energy storage system, the power generation condition mainly comprises illumination condition, and the power generation condition of the photovoltaic energy storage system is calculated to be met when the light intensity reaches a certain intensity, therefore, the first energy supplementing time is the time from the current time point to the time point when the first user arrives at the campsite and the light intensity reaches a certain intensity, and can be understood;
