Description

Electric automobile direct current charging system and charging control method thereof
Technical Field
The invention relates to the technical field of electric automobile charging, in particular to an electric automobile direct current charging system and a charging control method thereof.
Background
At present, the energy sources of the traditional fuel automobiles mainly depend on petroleum, and the environment is seriously polluted by the shortage of petroleum and the tail gas discharged by the fuel, so that people are increasingly urgent to research new green vehicles. As a green transportation tool, the electric automobile has remarkable energy-saving effect, greatly improves the comprehensive energy utilization rate, has zero emission of tail gas and remarkable environmental benefit, and is widely used.
The power of the electric automobile comes from a power battery, and the low charging speed and short endurance mileage of the power battery are key factors for restricting the large-scale popularization of the electric automobile. In view of the slow development of the energy density of the power battery, the adoption of high-current rapid charging can be used as a key condition for popularizing the electric automobile in the current stage. However, the current carrying capacity of the charging gun line is limited by the hardware condition of the charging gun line, so that the single-gun charging cannot meet the trend of high-current rapid charging.
At present, many manufacturers adopt a multi-gun charging mode to realize high-current quick charging, and the adopted charging control method is that each charging gun outputs an average current to meet the BMS (battery management system) request current value, for example, when two charging guns are adopted to charge a power battery, if the power battery request current is 500A, the two charging guns respectively output 250A current.
Although the control method can meet the requirement of high-current quick charge, the line loss of the charging guns is too high, and the cost is increased, for example, when two charging guns are adopted to charge the same power battery, if the maximum current carrying capacity of each charging gun is assumed to be 250A, and if the current required by charging the power battery is 500A, the two charging guns need to output 250A of current respectively; when the current required by the charging of the power battery is changed into 200A according to the current battery parameters (SOC, battery temperature, single voltage and the like), two charging guns are required to output 100A current respectively, and at the moment, the power battery requirement can be met by only outputting one charging gun, and the two charging guns are not required to be used at the same time, so that excessive loss is caused.
The output current of the charging gun is provided by the charging modules in the charger, and the maximum output capacity of each charging module is the same, if the maximum output current of each charging module is 20A, 13 charging modules are needed when the charging gun needs to output the charging current of 250A, wherein 12 charging modules all provide the current of 20A, and the other charging module provides the current of 10A. At present, all charging modules in the charger are adjustable in output, and if each charging module can output 0 to 20A of current, the control logic is complex, the stable output of the charging module is affected, the accuracy of the output current of the charging gun is easy to cause, and the error is large.

Further, if the maximum output current of the adjustable charging module and the rated output current of each rated charging module are both L, the number n of the rated charging modules selected according to the formula n×l is less than or equal to B < (n+1) ×l, and the current value output by the adjustable charging module is B-n×l.
