An embodiment of the utility model provides a fill power supply system who trades power station, this fill power supply system who trades power station can be used to charge or change electric automobile's battery package. Fig. 1 is a block diagram of a power supply system of a charging and replacing power station according to an embodiment of the present invention. As shown in fig. 1, the power supply system of the charging and replacing power station includes a battery management module 10, an electricity meter 20, and an electrical load 30. The electricity load 30 is electrically connected to the power grid 200 and the battery management module 10 through the electricity meter 20; the electricity load 30 is used for consuming the electric energy provided by the power grid 200 and/or the battery management module 10; the electricity meter 20 is used for displaying electricity quantity information according to the electric energy consumed by the electric load 30; the battery management module 10 includes an energy management unit 11 and a charge-discharge machine 12; the energy management unit 44 is electrically connected to the charge and discharge machine 12; the energy management unit 11 is configured to collect the electric quantity information displayed by the electric meter 20, start the charging and discharging machine 12 according to the electric quantity information to control the idle battery pack 310 to discharge, and provide the discharging electric energy of the idle battery pack 310 to the electric load 30; the discharge power of the idle battery pack 310 is less than or equal to the power information displayed by the power meter 30.
Specifically, the charging and replacing power station can provide services of charging and replacing a battery pack for the electric vehicle, and the electric load 30 in the power supply system of the charging and replacing power station may include, for example, a charger for charging the battery pack in the electric vehicle and/or a replacing channel for assisting the electric vehicle to replace the battery pack. When the charger charges the battery pack of the electric vehicle and/or the electric vehicle is replaced in the battery replacement channel, corresponding electric energy needs to be consumed. There are usually many battery packs in the charging and replacing station for replacing the electric vehicle, and when there are fewer electric vehicles needing to replace the battery packs, there are a lot of idle battery packs 310. At this time, the energy management unit 11 in the battery management module 10 can collect the electric quantity information displayed by the electric meter 20 to obtain the total electric energy required by the current electric load 30; the energy management unit 11 controls the charging and discharging machine 12 to start, the charging and discharging machine 12 controls the idle battery pack 310 to discharge, and the discharging electric energy of the idle battery pack 310 is less than or equal to the total electric energy required by the electric load 30, so as to prevent the charging and discharging machine 12 from controlling the idle battery pack 310 to discharge more discharging electric energy and less total electric energy required by the electric load 30, which causes the discharging electric energy of the idle battery pack 310 to have surplus, so that the discharging electric energy flows to the power grid 200, thereby generating unnecessary waste and increasing the operation cost of the charging and discharging station; meanwhile, since the discharge electric energy of the idle battery pack 310 is usually direct current, and when the direct current flows back to the power grid 300, a certain damage is caused to the power grid 300, the discharge electric energy of the idle battery pack 310 is controlled to be smaller than the electric energy required by the power load 30, so that the power utilization safety can be improved, and the charge and discharge station can operate safely and stably.

The electric energy required by the electric load 30 may be, for example, the current IL and the power PL required by the electric load 30, and the discharge electric energy of the idle battery pack 310 may also be the current IM and the power PM of the electric energy discharged by the idle battery pack. Wherein IL is more than or equal to IM, PL is more than or equal to PM.
Furthermore, in the embodiment of the utility model provides an in, idle battery package can be for filling trade the battery package that is not used in the power station at present, perhaps for filling trade the battery package that need carry out the maintenance of discharging in the power station. So, when maintaining the battery package through discharging, can provide its electric energy of discharging to the power consumption load, prevent that the electric energy is extravagant, and then improve the electric energy availability factor who fills and trade the power station to and reduce the running cost who fills and trade the power station.

Specifically, the power grid 200 can convert, transmit and distribute electric energy to provide electric energy for electric equipment, so as to meet the needs of life and production. In general, electricity consumption equipment is more in operation in daytime, and electricity consumption is more, so that more electric energy is needed to meet the electricity consumption requirement; and the electricity consumption equipment that runs is less when evening, and the power consumption is less, therefore less electric energy can satisfy user's demand. The electric energy utilization is unbalanced due to the limitation of the operation time of the electric equipment, and the national power grid divides the electric energy transmitted and distributed by the power grid 200 into peak power and valley power. The electric energy used in the peak period of electricity utilization is peak electricity, and the unit price is higher; the electric energy used in the electricity consumption valley period is valley electricity, and the unit price is lower. At this time, during the valley power, the unit price of the electric energy provided by the power grid 200 is low, and the energy management unit 11 may start the charge and discharge machine 12 to charge all the idle battery packs 310 in the current charging and replacing power station, so as to improve the utilization rate of the electric energy transmitted in the power grid 200 during the valley power; at peak power, the unit price of the power provided by the power grid 200 is high, and the energy management unit 11 may start the charge and discharge machine 12 to control the idle battery pack 310 to discharge, so as to reduce the use of the power transmitted by the power grid 200.

The preset electric quantity may be, for example, 90% of the total electric quantity of the idle battery pack 310, that is, when the remaining electric quantity of the idle battery pack 310 is less than 90% of the total electric quantity, the charge and discharge machine 12 may charge the idle battery pack 310, so that when the idle battery pack 310 needs to be replaced as a replacement battery pack with a battery pack in an electric vehicle, it can be ensured that the idle battery pack 310 has sufficient electric quantity.
