And judging whether the port occupation information and the current energy storage electric quantity meet the preset charging condition, and acquiring the charging type of the charging output port meeting the preset charging condition as a target charging type according to the judging result.
Specifically, the preset charging conditions are conditions for judging and screening the charging output ports of each charging type. If the charging type includes a charging output port satisfying a preset charging condition, the charging output port in the charging type is indicated to be available for normal use, that is, the charging type is determined to be the target charging type. If the charging type does not include the charging output port meeting the preset charging condition, the charging output port in the charging type cannot be used. For example, the charging type may be direct current overcharge, direct current rapid charge, alternating current charge. Configuration information of the charging output port corresponding to each charging type is shown in table 1.
TABLE 1
The specific steps for determining the target charging type include: determining that the charging type with the number of the vacant ports being greater than zero is an alternative charging type according to the port occupation information; the spare port is the unoccupied charging output port; determining judging conditions matched with each alternative charging type in the preset charging conditions; judging whether the current energy storage electric quantity and the total power of the alternating current input meet the judging conditions corresponding to the alternative charging types or not; and determining the charging type to which the charging output port meeting the judging condition corresponds as a target charging type.
And determining that the charging type with the number of the vacant ports larger than zero is an alternative charging type according to the port occupation information, namely judging whether unoccupied charging output ports contained in each charging type are larger than zero according to the port occupation information, and determining that the charging type is the alternative charging type if unoccupied charging output ports are contained in the charging type.
Determining the judging conditions matched with each alternative charging type in the preset charging conditions, wherein the preset charging conditions comprise a plurality of judging conditions, and then the judging conditions matched with the alternative charging types can be obtained from the preset charging conditions.
And judging whether the current energy storage current meets the judging condition corresponding to the alternative charging type according to the determined judging condition, thereby obtaining a judging result. And acquiring the alternative charging type corresponding to the charging output port meeting the judgment condition as the target charging type according to the judgment result.
In a specific embodiment, the determining the judging condition matched with each alternative charging type in the preset charging conditions includes: calculating the electric quantity requirement value corresponding to each alternative charging type according to the charge completion degree corresponding to the occupied port in the port occupation information; acquiring pre-consumption electric quantity corresponding to each alternative charging type from the preset charging conditions; and adding the electric quantity required value of each alternative charging type and the pre-consumed electric quantity and configuring the judgment condition matched with each alternative charging type.
Specifically, the occupied charging output port is an occupied port, and the charging completion degree corresponding to each occupied port can be obtained, and the charging completion degree corresponding to each occupied port is the completion degree value of the rechargeable battery in the new energy electric automobile electrically connected with the occupied port. The electric quantity demand value corresponding to each alternative charging type can be calculated according to the charging completion degree corresponding to the occupied port, and specifically, the electric quantity demand value is the electric quantity information which is expected to be consumed when the new energy electric automobile corresponding to the occupied port is charged.
The direct current fast charging and direct current over charging both need to consume the electric quantity of the energy storage battery assembled in the charging station, and the alternating current charging is directly carried out through alternating current commercial power without consuming the electric quantity of the energy storage battery. For the charging type of ac charging, the pre-consumed power is a product value of the number of occupied ports corresponding to the charging type and the charging power, for example, the number of occupied ports corresponding to the charging type of ac charging is 10, the ac output power of each port is 7kW, and the corresponding pre-consumed power is 70kW.
For direct current fast charge or direct current overcharge, the battery power to be consumed corresponding to each occupying port can be obtained through calculation according to the following formula (1):
Wherein d is a charging type coefficient, and specific numerical values of different charging types d are different; for example, the power consumption is more in the direct current overcharging process, the value of d is configured to be higher, the power consumption is smaller in the direct current rapid charging process, and the value of d is configured to be lower. For example, d has a value corresponding to the dc fast charge of 0.42 and a value corresponding to the dc overcharge of 0.48. And R is the charge completion degree corresponding to a certain occupied port, the value range of R is [0,1], R is the calculated battery power to be consumed corresponding to the occupied port, and the value range of R is [0,1].
After the electric quantity of the battery to be consumed of each occupying port in the same charging type is calculated, the electric quantity of the battery to be consumed of each occupying port in the same charging type is overlapped, so that an electric quantity requirement value corresponding to the charging type is obtained.
Further, determining the pre-consumed power corresponding to each of the alternative charging types in the preset charging condition, if R in the formula (1) is set to "0" (it is assumed that the extreme case is that no electric energy is stored in the rechargeable battery to be charged), the obtained power R of the battery to be consumed is the power of the energy storage battery to be consumed when the rechargeable battery corresponding to the charging requirement input by the user is fully charged. In a more specific embodiment, the initial completion degree input by the user in the charging requirement can also be obtained, and the value of r corresponding to the calculated pre-consumption power is not necessarily "0", that is, the corresponding pre-consumption power can be more accurately determined according to the actual power of the rechargeable battery that needs to be charged.
And adding the electric quantity required value of each alternative charging type and the pre-consumed electric quantity and configuring the electric quantity required value and the pre-consumed electric quantity as the judging condition matched with each alternative charging type. For example, for the charging type of ac charging, the pre-consumed electric power is that the ac output power is newly increased by 7kW, and the 7kW is added to the calculated electric power demand value to obtain the corresponding judgment condition. And aiming at two charging types of direct current quick charging and direct current super charging, superposing the calculated electric quantity requirement value and the corresponding pre-consumed electric quantity, and configuring the electric quantity requirement value and the corresponding pre-consumed electric quantity as corresponding alternative charging types.
Further, if the alternative charging type is direct current fast charging or direct current super charging, judging whether the current energy storage current is not smaller than an electric quantity accumulated value set in the corresponding judging condition; if the alternative charging type is alternating current charging, judging whether the total power input by alternating current is not smaller than the electric quantity accumulated value set in the corresponding judging condition, wherein the total power input by alternating current is the total power value input by commercial power. Through the judging process, whether the current energy storage electric quantity and the total power input by alternating current meet the judging conditions corresponding to the alternative charging types or not can be judged.
Further, charging payment prices corresponding to the target charging types are obtained according to the electricity price information corresponding to the current time. Further, corresponding electricity price information can be obtained according to the current time, and charging payment prices corresponding to each target charging type can be obtained according to the electricity price information and the current time. After the charging payment prices corresponding to the target charging types are obtained, the charging payment prices can be sent to the client for the user to select.
In a specific embodiment, step S130 includes the sub-steps of: acquiring charging cost corresponding to each target charging type according to the electricity price information corresponding to the current time; acquiring charging service costs of each target charging type according to the service period corresponding to the current time and the charging loss corresponding to each target charging type; and superposing the charging service cost and the charging cost corresponding to each target charging type to obtain a corresponding charging payment price.
Specifically, the charging cost corresponding to each target charging type can be obtained according to the electricity price information corresponding to the current time. Firstly, corresponding peak-valley time periods are determined according to the current time, and corresponding current commercial power price is determined according to the peak-valley time periods. Generally, the electricity price distinguishes the price of the commercial power of peak sections (07:00-11:00 and 19:00-23:00), the price of the commercial power of valley sections (23:00-7:00) and the price of the commercial power of flat sections (11:00-19:00), and the corresponding commercial power prices of different time periods are different. For example, when the current time is 9:15, the peak-valley period of the electricity consumption correspondingly determined is a peak section, and the commercial electricity price (commercial electricity consumption) of the peak section is further determined to be 1.2 yuan/kW.h.
The obtained commercial power price is the charging cost corresponding to each target charging type, and the charging costs of different charging types determined at the same time are the same. Further, according to the current time and the charging loss of different charging types, the charging service cost corresponding to each target charging type can be determined. And superposing the charging service cost and the charging cost corresponding to each target charging type to obtain a corresponding charging payment price.
In a specific embodiment, the obtaining, according to the service period corresponding to the current time and the charging loss corresponding to each target charging type, the charging service cost corresponding to each target charging type includes: acquiring a cost coefficient value corresponding to a service period matched with the current time; obtaining loss coefficient values of the charging loss corresponding to the target charging types; and calculating the cost coefficient value and the loss coefficient value according to a preset service cost coefficient calculation formula to obtain the charging service cost.
Different service periods correspond to different service costs, different charging types correspond to different charging losses, and then the corresponding service periods can be determined according to the current time. For example, the service period can be divided into a low peak service period, a flat peak service period, a peak no-sunlight service period, and a peak sunlight service period, wherein the time interval corresponding to the low peak service period is [21:01-7:00], and the time interval corresponding to the peak sunlight service period is [7:01-11:00], [16:31-18:00]; the time interval of the peak sunlight-free service period is [18:01-21:00], the time interval of the peak service period is [11:01-16:30], the corresponding service period can be determined according to the time interval of the current period, and the cost coefficient of the corresponding service period is obtained. For example, the cost coefficient corresponding to the low peak service period is "0.15", the cost coefficient corresponding to the flat peak service period is "0.3", the cost coefficient of the peak no-sunlight service period is "0.6", and the cost coefficient of the peak sunlight service period is "0.5" (the energy storage battery configured in the charging station is charged by the photovoltaic power generation, and the corresponding service cost is lower).
Further, the loss coefficient value corresponding to the target charging type is obtained, the loss of the electric energy in the charging process is different from the different charging types, and the higher the charging speed is, the heating value is correspondingly increased, and the loss rate of the electric energy is also higher.

And acquiring a group of battery charging and discharging data which is pre-stored and matched with the initial detection information, and acquiring corresponding detection charging parameters by combining the initial detection information and the battery charging and discharging data. For example, multiplying the highest voltage of the battery cells by the number of series connections of the battery cells to obtain the maximum allowable charge voltage of the battery pack; the number of the single-cell series-connected battery packs is multiplied by the single-way maximum current, so that the maximum allowable current of the battery packs is obtained.

The State of charge detection information may include SOH information (State of Health), SOP detection information, and temperature detection information.

The method comprises the steps of charging the constant current to a preset capacity ratio, and then charging the constant current to a constant voltage until the constant current is full. If constant current charging is always adopted, the polarization of the battery core is increased, so that the battery can reach the cut-off voltage quickly, and the battery electric quantity is not fully charged at this time, so that the charging efficiency of the battery can be improved by adopting the charging strategy, and the battery is fully charged.

Further, it is determined whether each of the values included in the charge state detection information is within a defined range corresponding to each of the values in the constraint condition, that is, whether each of the values is not greater than the corresponding constraint value in the constraint condition. If all the numerical values are in the corresponding limiting ranges, judging that the charging state detection information meets the limiting conditions; if at least one numerical value is not in the corresponding limiting range, the state of charge detection information is judged to not meet the limiting condition.
