When the power system is in a peak value state, when the switching control unit monitors that the power battery in a single battery compartment discharges to reach 10% of electric quantity and the two battery compartments release 20% of electric quantity of the power battery in total, the switching control unit cuts off the power supply of the battery compartments to the charging pile, and the charging pile is switched into a power grid for supplying power. In addition, in the flat time period or the valley time period of the power grid, the charging power of the charging pile module is reduced to be lower than 80% of the rated charging power, and the power batteries in the two groups of battery bins are properly arranged to perform shallow charging and shallow discharging in turn (the charging and discharging amount is controlled to be within 10% of the total electric quantity). Thus, the utility model discloses the utilization fills the characteristics of electric pile distributed layout, will trade power battery storehouse for the electric power site and fill electric pile and carry out organic combination, it is big to have solved the centralized electric power site land used scale of trading of overall arrangement on the one hand, once invest in too big problem, on the other hand, make the battery in the power battery storehouse can realize shallowly filling shallow discharge through switching control unit, the full electric maintenance function of idle time, and make the electric wire netting, battery energy has obtained better optimization, the battery storehouse in addition, the switching access of filling electric pile has reduced the impact of large capacity charge load to the electric wire netting, help improving local electric wire netting load characteristic. Finally, charging and battery replacement are organically unified, battery replacement can be realized at a charging point, and the power utilization state can be set according to the peak value, normal time and valley time periods of the power grid, so that the problem of power grid settlement is solved, the energy utilization state can be optimized, and the power utilization cost is greatly reduced.
The utility model can be further embodied as
The switching control unit is installed in the convergence module.
This facilitates the common implementation in the electrical part and the control part.
When power battery storehouse is two, these two power battery storehouses are located the both sides of filling electric pile respectively.
Considering to fill electric pile self and taking up an area of the problem, the power battery storehouse that combines does not exceed 2, from the requirement of charging and discharging, 1-2 power battery storehouse is enough with fill the organic interaction of carrying out the charge-discharge between electric pile, the electric wire netting.
To sum up, the utility model provides a fill electric pile device based on fill, trade the bimodulus, will trade electric power battery storehouse for the net point and the electric pile that fills of the net point of charging and carry out organic combination, realized filling, trade the distributed layout of electricity, be favorable to promoting user experience, it is big to have solved the centralized electric power net point land used scale of trading of overall arrangement, the problem of once investing in too big, the battery in the electric power battery storehouse can realize shallowly filling and has put, the full power dimension of idle time is supported the function, and make the electric wire netting, battery energy has obtained better optimization, battery storehouse in addition, the switching access of filling electric pile has reduced the impact of large capacity charge load to the electric wire netting, help improving local electric wire netting load characteristic, the electric wire netting settlement problem has been solved promptly, also can optimize the energy consumption state simultaneously, the power consumption.
