Description

TECHNICAL FIELD

[0002] With the development of renewable energy technologies, photovoltaic power generation, wind power generation and hydroelectric power generation technologies have been widely applied in the global range. However, a single type of power generation method is often limited by environmental factors and is difficult to achieve the best effect in various environments. In addition, the popularity of electric vehicles and other electric devices has led to a sharp increase in the demand for charging infrastructure.

[0003] The power transmission method of the traditional power distribution network is to use a power distribution transformer to increase the voltage at the power plant end, use high-voltage lines to transmit power to the power consumption location, and then use a transformer to reduce the voltage. Due to the resistance in the line, power loss will occur on the line resistance during power transmission. In order to save energy and reduce power transmission loss, the distribution of circuits in remote areas will be reduced, which leads to a relative lack of power supply in remote areas. With the increasing distribution of electric vehicles and other electric devices in remote areas, a large number of charging piles need to be equipped. However, when electric vehicles are charging, it will have a great impact on power consumption in remote areas. In order to reduce the impact of electric vehicle charging on power consumption in remote areas, the number of charging piles must be reduced. Therefore, the problem of electric vehicle charging is becoming increasingly serious. In the prior art, energy storage batteries are used to store energy during the low power consumption period of electric vehicles, and the energy storage batteries are used to supply power to electric vehicles during the peak power consumption period. However, due to the loss of the battery, after the energy storage battery is used for a certain period of time, the ability of the energy storage battery pack to supply power to the electric vehicle will be greatly reduced, and only a large number of energy storage battery packs can be maintained, which leads to the stop of the operation of the charging station.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] Example 1:

[0045] See also Figure 1 As shown, the present invention discloses a modular power storage and charging control method, comprising the following steps:

[0046] S10. Determine whether there is an energy storage battery pack that needs to be replaced.

[0047] S11. If yes, determine whether the energy storage battery pack is an energy storage battery pack in use. S111. If yes, assign the energy storage battery pack from the in-use battery pack to the battery pack to be replaced, and update the stored power information of the in-use battery pack in the energy storage module; S112. If no, assign the energy storage battery pack from the to-be-used battery pack to the to-be-replaced battery pack, and update the stored power of the to-be-used battery pack;

[0048] If no, proceed to the next step;

[0049] S20 obtains the energy storage module storage capacity information, and uses the control module to calculate the subsequent chargeable capacity of the charging module;

[0050] S30. Determine whether the current storage capacity of the energy storage module meets the subsequent charging demand,

[0051] S31. If not, the charging module is called to charge, and the process returns to step S20.

[0052] S32. If yes, the process ends.

[0053] In this embodiment, there are in-use energy storage battery packs, standby battery packs, and replacement battery packs. Each of the in-use energy storage battery packs, standby battery packs, and replacement battery packs is composed of a plurality of battery elements connected in series to form a battery pack assembly, and a plurality of battery pack assemblies are connected in parallel to form the in-use energy storage battery packs, standby battery packs, and replacement battery packs. Each battery pack assembly is connected to a multi-stage switch, which is used to switch the damaged battery pack assembly in the in-use energy storage battery pack to the replacement battery pack, switch the damaged battery pack assembly in the standby battery pack to the replacement battery pack and / or the replacement battery pack, and switch the battery pack assembly in the replacement battery pack to the standby battery pack.

[0054] In addition, the ratio of the battery discharge capacity to the battery charging capacity η 实际 The battery itself is greatly affected by its own loss. The total energy storage capacity of the energy storage battery needs to be calculated in combination with the environmental temperature, battery aging, and power conversion efficiency. Therefore, replacing the battery pack whose power conversion efficiency is greatly affected by the battery loss that is too serious is beneficial to the accurate control of the storage capacity information of the energy storage module in the subsequent application, and at the same time, it is convenient to determine whether the current storage capacity of the energy storage module meets the subsequent charging demand.

[0055] In some embodiments, the method further includes obtaining the battery loss information of all energy storage battery packs in the energy storage module, and the specific steps are as follows:

[0056] Based on the battery rated capacity C 额定 , the actual capacity C 实际 of the battery, the battery loss P 损 of all energy storage battery packs in the energy storage module is obtained.

[0057] In some embodiments, the method further includes the following steps:

[0058] Based on the battery state H and the depth of discharge D, the state of charge S is obtained.

[0059] In this embodiment, the formula for the battery dischargeable capacity is:

[0060]

[0061] where S is the ratio of the dischargeable capacity to the rated capacity, C r is the capacity released when fully discharged, and C 额定is the rated capacity;

[0062] The battery state formula is:

[0063]

[0064] wherein H is the battery state, C max is the maximum releasable capacity of the battery, C 额定 is the rated capacity;

[0065] The discharge depth formula is:

[0066]

[0067] wherein D is the discharge depth, C r is the capacity released when fully discharged, C 额定 is the rated capacity;

[0072] wherein D(t0) is the discharge depth in the initial state, ΔD is the discharge depth change in the working period, and D(t) is the discharge depth at time t.

[0073] Combined with S(t) = H(t) - D(t) (6);

[0074] wherein D(t) is the discharge depth at time t, H(t) is the battery state at time t, and S(t) is the state of charge at time t.

[0075] It can be known that, in the discharging mode, the discharge depth D accumulatively consumes the charge, and in the charging mode, the discharge depth D decreases with the accumulated charge entering the battery, and the state of charge S can be estimated by subtracting the discharge depth D from the battery state H.

[0076] In addition, the battery loss formula is:

[0077]

[0078] wherein C 额定 is the rated capacity, C实际 H is the actual capacity of the battery, P 损 P is the loss of the battery;

[0079] In combination with the battery state H and the loss P 损 of the battery, the loss of the battery can be known.

[0083] In some embodiments, the specific steps of "allocating the storage battery pack from the in-use battery pack to the battery pack to be replaced, and updating the storage capacity information of the in-use battery pack in the storage module" are as follows:

[0084] According to the total capacity of the in-use battery pack before the battery pack marked as damaged is disconnected, the capacity of the battery pack marked as damaged, and the total capacity of the in-use battery pack after the battery pack marked as damaged is disconnected, the actual total capacity of the in-use battery pack after the battery pack marked as damaged is disconnected is obtained.

[0085] The specific steps of obtaining the "capacity of the battery pack marked as damaged" are as follows:

[0086] Among the plurality of in-use battery packs in parallel, the battery pack marked as damaged is disconnected from the in-use battery pack circuit and connected to the capacity detector circuit to obtain the capacity of the battery pack marked as damaged.

[0087] In some embodiments, the specific steps of "allocating the storage battery pack from the standby battery pack to the battery pack to be replaced, and updating the storage capacity of the standby battery pack" are as follows:

[0089] The specific steps of obtaining the "capacity of the battery pack marked as damaged" are as follows:

[0090] In parallel, the battery group marked as a damaged state is disconnected by the to-be-used battery group circuit, connected to the power detector, and the power of the battery group marked as a damaged state is obtained.

[0091] In some embodiments, the "calculating the subsequent chargeable amount of the charging module by the control module" specifically includes the following steps:

[0092] According to the sunshine duration in the weather website, the actual received light data of the solar panel in the corresponding period, and the time synchronization system, the subsequent solar power generation amount of the solar power generation module is obtained.

[0093] According to the wind speed and direction in the weather website, the actual power generation data of the wind turbine in the corresponding period, and the time synchronization system, the subsequent wind power generation amount of the wind turbine is obtained.
