The charging control system in the embodiment of the invention comprises an energy presetting module 2, an energy calculating module 3, an electric quantity calculating module 4, an electric quantity-energy management system 5 and a charging center 6, and the connection relation and the function of each module are respectively explained in the following contents. The charging control system also comprises other signal acquisition modules in battery charging and the like, and the signal acquisition modules are not shown in fig. 2 because the direct connection with the charging control system is not generated, and the battery is marked as 1 in fig. 2.
The first step of the control method of the embodiment of the invention comprises the steps of presetting the charging electric energy corresponding to each unit of electric quantity to form a first charging curve; dividing the factory electricity charge according to each unit of electricity, obtaining a first electricity-electricity curve according to the divided each unit of electricity and the first charging curve, and storing the first electricity-electricity curve; the first charging curve is obtained according to an offline charging and discharging process of the battery or the first time of experimental discharging detection of the same type of battery, and the relation curve can be obtained.
Here, the energy presetting module 2 presets the charging electric energy corresponding to each unit of electric quantity to form a first charging curve, the energy presetting module 2 transmits the first charging curve to the electric quantity-electric energy management module 5, the electric quantity-electric energy management module 5 divides the factory electric charge quantity according to each unit of electric quantity, and a first electric quantity-electric energy curve is obtained and stored according to the divided each unit of electric quantity and the first charging curve;
secondly, calculating charging electric energy corresponding to each unit of electric quantity charged into the battery in real time in the charging process of the battery, obtaining a second electric quantity-electric energy curve according to each unit of electric quantity and the corresponding charging electric energy, and storing the curve;
the total electric quantity of the battery is set into a plurality of unit electric quantity units according to a set metering unit and is sequentially arranged, and each unit electric quantity corresponding to the factory electric charge is arranged before each unit electric quantity corresponding to the charged electric charge.
Here, the first and second charge-power curves may be curves according to the same or different variation trends.
The electric quantity-electric energy management module 5 sets the total electric quantity of the battery to be a plurality of electric quantity units of unit size, which are sequentially arranged, and the plurality of electric quantity units of unit size are set according to the rule of input first and output second.
The electric quantity-electric energy management module 5 records the electric quantity units of each unit and the corresponding charging electric energy in a one-to-one correspondence manner according to the obtained factory electric charge quantity and electric energy data and the electric quantity and the energy data of the battery in the charging process, and each unit of electric quantity corresponding to the factory electric charge quantity is arranged before each unit of electric quantity corresponding to the charging electric quantity. For example, the total charge of the battery is modeled as a unit-size unit of charge that meets the first-in last-out rule, denoted Qi, i as 1,2,3 … …, m. The charging power corresponding to each electric quantity unit is different and is marked as Ei, i is 1,2,3 … …, n.

Thus, after the battery is charged, the quantity-energy management module 5 sequentially records the quantity-energy relationships (Q1, E1), (Q2, E2), (Q3, E3) … … (Qm, Em) into the queue.
Then, during the discharging process of the battery, the discharged amount is recorded, and here, the electric quantity during the discharging process of the battery is calculated by the electric quantity calculation module 4, in this embodiment, the unit electric quantity units in the battery are arranged to be discharged and used in sequence according to the reverse sequence of the charging sequence, so that each unit electric quantity corresponding to the factory electric charge is arranged to be used after each unit electric quantity corresponding to the charged electric quantity.

According to the process, the electric energy corresponding to the factory electric charge is obtained by presetting the factory electric charge, the factory electric charge and the charged electric charge are placed according to the set rule, and the discharge electric energy corresponding to the factory electric charge can be obtained according to the discharge set rule in the charging process, so that accurate consumption amount can be obtained.
Finally, it should be noted that, in the next charging process, each unit of electric energy obtained by charging is arranged after each unit of electric energy corresponding to the remaining electric energy after the last discharge of the factory electric charge. For example, the factory charge amount accounts for 20% of the total charge capacity of the battery, the first charging is supplemented by 80% to full charge, in the first discharging process, 90% of the total charge capacity of the battery is used for discharging, according to the discharging rule of the application, it can be considered that 10% of the factory charge amount still remains, then in the next charging process, 90% of the total charge capacity of the battery needs to be supplemented to full charge, and the steps are sequentially circulated until the factory charge amount is consumed, and if the factory charge amount is consumed, then 100% of the total charge capacity needs to be supplemented to full charge in the charging process.
In the case of a rechargeable battery of an electric vehicle, errors accumulated in metering, self-discharge of the battery, and self-degradation of the battery during use may cause a problem in that the electric energy recorded by the electric energy-energy management system is used up, but the battery is still discharging, and therefore, inaccurate calculation of electric energy of the battery due to the errors and the like needs to be compensated and corrected.
In the embodiment of the present application, the method for controlling battery discharge charging further includes the steps of,
setting a preset range value of the battery charge quantity of the battery leaving a factory, and obtaining energy corresponding to the preset range value of the battery charge quantity according to the first charging curve; and calculating the average value of all the energies corresponding to the preset range value, wherein the preset range value is generally set to be 0-M% of the battery charge of the battery factory, and M can be 10, 15 or 20. However, as will be understood by those skilled in the art, the predetermined range value may be selected according to actual conditions, and the metering error is usually within 10%, so that the predetermined range value may be set to 0-10% or 0-20% of the battery charge of the battery from which the battery leaves the factory.
When the battery runs and discharges, and when the charge quantity stored in the battery is discharged and the battery is still discharged, the average value of all the energy corresponding to the preset range value is adopted to compensate the charging electric energy actually consumed by the battery, specifically, the average value of all the energy corresponding to the preset range value and the charging electric energy actually consumed by the battery are adopted to carry out superposition calculation, namely, the electric energy obtained by calculation of the average value and the charging electric energy actually consumed by the battery are superposed, and the electric charge is calculated according to the superposed electric energy, so that the calculation inaccuracy caused by factors such as errors can be compensated, and the accuracy of the charging calculation of the battery can be further improved.
It will be understood by those skilled in the art that, in the embodiment of the present invention, the calculation of the amount of electricity or the electric energy may be performed by calculating the charging electric energy consumed by the battery during the charging process and the instantaneous current from the instantaneous voltage of the battery in the current operating state (e.g. during the charging process or the discharging process), and calculating the amount of electricity obtained by the battery during the charging process, etc., which is a conventional technology and will not be described in detail herein.
