Technical Field

The present invention relates to the technical field of electric vehicle charging and battery replacement, and in particular to a battery replacement station, a charging control method, an electronic device and a computer storage medium.

Background technique

The existing methods of charging electric vehicles are divided into battery replacement and direct charging. The number of battery replacement vehicles and direct charging vehicles in different regions is different and will continue to change. The charging demand of the two types of electric vehicles in different time periods also changes continuously. In particular, the cost of building new charging equipment such as high-power charging piles is too high, but the demand is unstable. Whether it is a battery swap station or a charging pile, there will be a phenomenon of charging equipment being in short supply or being idle, resulting in waste or tension of charging resources.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the defects in the prior art that the cost of building new charging equipment alone is too high but the demand is unstable, resulting in waste or shortage of charging resources, and to provide a battery swap station, a charging control method, an electronic device and a computer storage medium.

The present invention solves the above technical problems through the following technical solutions:

The present invention provides a battery swap station, which includes a power supply system, a first charging device and a second charging device, wherein the first charging device and the second charging device are electrically connected to the power supply system respectively, the first charging device is used to charge the battery swap in the battery swap station, and the second charging device is used to charge the electric vehicle. Preferably, the first charging device includes a bidirectional charging module; the power supply system charges the battery swap through the bidirectional charging module; and/or the battery swap battery discharges to the power supply system through the bidirectional charging module. This scheme is based on setting a first charging device and a second charging device in the battery swap station, the first charging device is used to charge the battery swap in the battery swap station, and the second charging device is used to charge the electric vehicle. The battery swap of the battery swap vehicle and the charging of the direct charging vehicle can be completed at the battery swap station. The charging resources of the battery swap station are distributed between the first charging device and the second charging device, which alleviates the waste or shortage of charging resources. No matter what kind of vehicle the owner drives, he can replenish electricity at the battery swap station, which improves the owner's experience. Furthermore, the battery swap battery and the power supply system are connected through a two-way charging module, so that the battery swap battery can switch between the charging state and the discharging state according to the actual power consumption, making full use of the characteristics of the battery swap battery. When the charging demand exceeds the output power of the power supply system, the battery swap battery can switch to the discharging state. The battery swap battery is incorporated into the power supply system through the two-way charging module, which not only improves the output power of the power supply system, but also reduces the charging demand of the battery swap battery, so that the second charging device can work normally; when the charging demand is less than the output power of the power supply system, the battery swap battery continues to charge, and the charging resources are reasonably allocated to prevent idleness and waste of charging resources.

Preferably, the power supply system includes a transformer, and a rated power of the transformer is less than the sum of maximum output powers of the first charging device and the second charging device.

This solution allocates the charging resources of the battery swap station so that the transformer in the power supply system does not need to meet the sum of the maximum power of the first charging device and the second charging device used simultaneously, thereby reducing the requirements for transformer specifications, reducing the construction and maintenance costs of the battery swap station, and avoiding idleness and waste of charging resources.

Preferably, there are multiple bidirectional charging modules, and each bidirectional charging module is electrically connected to one battery replacement battery;

When the sum of the expected output powers of the first charging device and the second charging device is greater than the rated power of the transformer, part or all of the battery-swap batteries discharge to the power supply system through the bidirectional charging module.

This solution accurately determines whether part or all of the swap batteries discharge into the power system through the bidirectional charging module based on the expected output power, thereby improving the charging efficiency.

Preferably, the battery replacement battery that discharges to the power system through the bidirectional charging module is a target battery whose SOC (State of Charge) value is within a preset SOC range.

This solution uses the SOC value of the battery swap battery to screen out the battery swap batteries that need to be switched to the discharge state, and selects batteries with appropriate SOC values for discharge to avoid affecting the reserve of the battery swap batteries. It can also prevent battery swap batteries with too low SOC values from being over-discharged and causing battery loss.

Preferably, the second charging device is a charging pile, and the power of the charging pile is greater than 200 kW (kilowatts).

This solution sets up high-power charging piles in the battery swap station. The high-power charging piles can reuse the charging resources in the battery swap station, thereby achieving high-speed charging of direct-charging vehicles at a lower cost, expanding the functional scope of the battery swap station and improving the user experience.

Preferably, the second charging device is a wireless charging device.

In this solution, the second charging device is configured as a wireless charging device, which is easy and safe to use, avoids the risk of sparks and electric shock, has no dust accumulation and contact loss, no mechanical wear and does not require corresponding maintenance, and can adapt to a variety of harsh environments and weather.

The present invention further provides a charging control method, which is applied to the battery swap station as described above, and includes:

configuring the first charging device and/or the power system according to the output requirement so that the second charging device meets the output requirement;

Preferably, the output requirement includes an expected output power.

The power supply system includes a transformer, and the first charging device includes a bidirectional charging module;

The step of configuring the first charging device and/or the power supply system according to the output requirement includes:

determining whether the sum of the estimated output powers of the first charging device and the second charging device exceeds the rated power of the transformer;

When the sum of the expected output powers of the first charging device and the second charging device exceeds the rated power of the transformer, the battery replacement batteries corresponding to some or all of the bidirectional charging modules are controlled to discharge into the power supply system.

This solution is based on the installation of a first charging device and a second charging device in the battery swap station. The first charging device is used to charge the battery in the battery swap station. Battery charging, the second charging device is used to charge electric vehicles. Both the battery swapping of battery swapping vehicles and the charging of direct charging vehicles can be completed at the battery swapping station. The charging resources of the battery swapping station are distributed between the first charging device and the second charging device, which alleviates the waste or shortage of charging resources and ensures that the second charging device can reach the expected output power, thereby ensuring the charging time of the directly charged vehicle and improving the charging experience of the direct charging vehicle owner. At the same time, no matter what kind of vehicle the owner drives, he can replenish electricity at the battery swapping station. Furthermore, based on the judgment that the sum of the expected output power of the first charging device and the second charging device exceeds the rated power of the transformer, the battery swapping batteries corresponding to some or all of the bidirectional charging modules are controlled to discharge to the power supply system, which not only increases the output power of the power supply system, but also reduces the charging demand of the battery swapping battery to meet the normal operation of the second charging device, so that the transformer in the power supply system does not need to meet the sum of the maximum power of the first charging device and the second charging device used at the same time, reducing the requirements for the transformer specifications.

Preferably, the power supply system includes a battery replacement battery and/or an energy storage battery, and the steps of configuring the first charging device and/or the power supply system according to the output demand include:

Control the battery replacement battery and/or the energy storage battery to supply power to the second charging device.

In this solution, the second charging device may be powered by a battery replacement battery in a battery replacement station used to replace batteries in battery replacement vehicles, or a storage battery used for power regulation, thereby ensuring the power supply of the second charging device.

Preferably, the step of controlling some or all of the battery replacement batteries corresponding to the bidirectional charging modules to discharge to the power supply system includes:

Obtaining a power difference between the sum of the predicted output powers and the rated power of the transformer;

The number of replacement batteries to be discharged into the power system and the discharge power are determined based on the power difference.

This solution accurately determines the number of swap batteries to be discharged into the power system and the discharge power based on the power difference between the sum of the expected output power and the rated power of the transformer, thus avoiding the waste of charging resources.

Preferably, the step of controlling some or all of the battery replacement batteries corresponding to the bidirectional charging modules to discharge to the power supply system includes:

This solution uses the SOC value of the battery swap battery to screen out the battery swap batteries that need to be switched to the discharge state, and selects batteries with appropriate SOC values for discharge to avoid affecting the reserve of the battery swap batteries. It can also prevent battery swap batteries with too low SOC values from being over-discharged and causing battery loss.

Preferably, the first charging device further includes a unidirectional charging module, and the power supply system supplies power to the battery replacement battery or the second charging device through the unidirectional charging module; the battery replacement battery electrically connected to the bidirectional charging module is a first battery replacement battery, and the battery replacement battery electrically connected to the unidirectional charging module is a second battery replacement battery;

The method further comprises:

Control the SOC value of the first battery-exchange battery to be higher than the SOC value of the second battery-exchange battery.

This solution is based on controlling the SOC value of the first battery exchange battery to be higher than the SOC value of the second battery exchange battery, thereby ensuring sufficient discharge capacity to supply the second charging device. It can also prevent the battery exchange battery with a too low SOC value from being in an over-discharge state and causing battery loss.

Preferably, the step of configuring the first charging device and/or the power supply system according to the output requirement further includes:

Detailed ways

The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

Example 1

Please refer to Figure 1, which is a first structural diagram of the battery swap station in this embodiment. Specifically, the battery swap station includes a power system 3, a first charging device 1 and a second charging device 2. The first charging device 1 and the second charging device 2 are electrically connected to the power system 3 respectively. The first charging device 1 is used to charge the battery swap in the battery swap station, and the second charging device 2 is used to charge the electric vehicle.

In an optional embodiment, the power supply system 3 includes a transformer 4, and the rated power of the transformer 4 is less than the sum of the maximum output powers of the first charging device 1 and the second charging device 2. Specifically, the user's electricity demand is not constant, but constantly changing. The charging demand is usually relatively stable, but there will be peak demand during certain periods. Although increasing the rated power of the transformer 4 will improve the charging efficiency during peak power consumption, it will lead to higher construction and maintenance costs, and the proportion of time periods at peak power consumption is not large, and most of the time periods will lead to idleness and waste of charging resources. Therefore, in practical applications, the requirements for the specifications of the transformer 4 can be reduced, and the rated power of the transformer 4 does not need to be greater than or equal to the sum of the maximum output powers of the first charging device 1 and the second charging device 2.

Please refer to Figure 2, which is a second structural diagram of the battery swap station in this embodiment. Specifically, in an optional implementation, the first charging device 1 includes a bidirectional charging module 11; the power system 3 charges the battery swap 5 through the bidirectional charging module 11; the battery swap 5 discharges to the power system 3 through the bidirectional charging module 11. The battery swap battery and the power system are connected through a bidirectional charging module, so that the battery swap battery can switch between the charging state and the discharging state according to the actual power consumption, making full use of the characteristics of the battery swap battery. When the charging demand exceeds the output power of the power system, the battery swap battery can be switched to the discharging state. The battery swap battery is incorporated into the power system through the bidirectional charging module, which not only increases the output power of the power system, but also reduces the charging demand of the battery swap battery, so that the second charging device can work normally; when the charging demand is less than the output power of the power system, the battery swap battery continues to charge, thereby rationally allocating the charging resources to prevent the idleness and waste of charging resources.

In an optional embodiment, there are multiple bidirectional charging modules 11, and each bidirectional charging module 11 is electrically connected to a battery exchange battery 5; when the sum of the expected output powers of the first charging device 1 and the second charging device 2 is greater than the rated power of the transformer, part or all of the battery exchange batteries 5 discharge to the power supply system 3 through the bidirectional charging module 11. Specifically, the expected output powers of the first charging device 1 and the second charging device 2 are obtained according to the operation conditions of the first charging device 1 and the second charging device 2, and then it is determined whether the sum of the expected output powers of the first charging device 1 and the second charging device 2 is greater than the rated power of the transformer. If it is determined to be yes, the state of part or all of the battery exchange batteries is switched, and the battery exchange batteries are discharged to the power supply system 3 through the bidirectional charging module to increase the total output power of the power supply system 3.

In an optional embodiment, the battery replacement battery that discharges to the power supply system 3 through the bidirectional charging module is a target battery whose SOC value is within a preset SOC range. Specifically, the battery replacement battery that is switched to the discharge state can be screened out by the SOC value of the battery replacement battery. For example, the selection of the preset SOC range can be specifically determined according to the battery replacement SOC standard to avoid affecting the reserve of the battery replacement battery. For example, if the battery replacement SOC standard is 95%, that is, the battery charged to more than 95% can be replaced for the battery replacement vehicle. In this case, a battery replacement battery with an SOC value greater than 95% can be selected for discharge and discharged to 95%; or a battery replacement battery with a large difference between the SOC value and the battery replacement SOC standard can be selected, such as a battery replacement battery with an SOC value less than 60%, to avoid causing the battery that is quickly charged to the battery replacement SOC standard to be discharged and affect the reserve of the battery replacement battery. At the same time, the lower limit value of the preset SOC range can also be set to prevent the battery replacement battery with a too low SOC value from being in an over-discharged state and causing battery loss, such as selecting a battery replacement battery with an SOC value greater than 30% for discharge. That is, in a preferred embodiment, a battery replacement battery with an SOC value greater than the battery replacement SOC standard and an SOC value between 30% and 60% can be selected for discharge.

Please refer to Figure 3, which is a third structural diagram of the battery swap station in this embodiment. Specifically, in another optional implementation, the first charging device 1 includes a selection module 12 and a unidirectional charging module 13, and the selection module 12 is electrically connected to the battery swap battery 5 and the second charging device 2 respectively.

Among them, when the selection module 12 is in the first state, the power system 3 charges the battery swap 5 through the unidirectional charging module 13; when the selection module 12 is in the second state, the power system 3 supplies power to the second charging device 2 through the unidirectional charging module 13. Specifically, for a battery swap station where the existing charging device is only equipped with a unidirectional charging module 13, an additional configuration selection module 12 can be configured. The selection module 12 and the unidirectional charging module 13 constitute the first charging device 1, and are electrically connected to the second charging device 2, so that the selection module 12 can select whether the power system 3 provides power to the first charging device 1 or to the second charging device 2.

In an optional embodiment, there are multiple one-way charging modules 13, each of which is connected to a battery replacement module. when the second charging device 2 is working, part or all of the unidirectional charging module supplies power to the second charging device 2.

In an optional embodiment, the selection module 12 includes a plurality of bus contactors; a preset number of unidirectional charging modules 13 are connected in parallel to the second charging device 2 through the bus contactors. Specifically, the bus contactor has a simple and stable structure, and can effectively realize the selection and switching control of the output of the unidirectional charging module 13. The bus contactor and the unidirectional charging module 13 constitute the first charging device 1, and are electrically connected to the second charging device 2. The bus contactor can select whether the power supply system 3 provides power to the first charging device 1 or to the second charging device 2.

In an optional embodiment, the second charging device 2 is a charging pile, and the power of the charging pile is greater than 200kW. Specifically, a charging pile with a power greater than 200kW is a high-power charging pile, which greatly improves the user's charging experience. However, during the entire battery charging process, usually only the section with a lower battery SOC value requires high-power charging, which has the defects of high cost and low demand. By configuring the high-power charging pile together with the first charging device for battery charging at the battery swap station, the high-power charging pile can reuse the charging resources in the battery swap station, thereby achieving high-speed charging of direct-charging vehicles at a lower cost, avoiding idleness and waste of charging resources, expanding the functional scope of the battery swap station, and improving the user experience.

In an optional embodiment, the second charging device is a wireless charging device. Specifically, the second charging device can be configured as a wireless charging device, which is not electrically connected to the electric vehicle through a wire, and does not require plugging and unplugging of charging connectors. It is easy and safe to use, avoids the risk of sparks and electric shock, and has no dust accumulation and contact loss, no mechanical wear and tear, and does not require corresponding maintenance, and is adaptable to a variety of harsh environments and weather.

In an optional embodiment, the battery swap station includes a battery swap point, and the electric vehicle is charged at the battery swap point through the second charging device 2. Specifically, the second charging device 2 in the battery swap station can be arranged near the battery swap point, and the battery swap vehicle and the direct charging vehicle share the same position, saving space in the battery swap station.

In another optional embodiment, the battery swap station includes a charging position, and the electric vehicle is charged at the charging position through the second charging device 2. Specifically, the battery swap position and the charging position can be separately set in the battery swap station to avoid mutual influence between the battery swap vehicle and the direct charging vehicle, thereby improving the efficiency and safety of the battery swap station.

In an optional embodiment, the battery swap station includes a plurality of battery swap points, and the plurality of battery swap points are arranged in an array parallel to or perpendicular to the driving direction. Please refer to Figure 4, which is a fourth structural schematic diagram of the battery swap station in this embodiment. As shown in Figure 4, this embodiment provides an array-type battery swap station, which includes a plurality of battery swap points 100, each of which is respectively configured with a second charging device 2, and the battery swap points 100 and the second charging device 2 are sequentially arranged perpendicular to the driving direction; by increasing the battery swap stations, more vehicles can be accommodated for battery swapping at the same time. Preferably, the second charging device 2 is arranged on one side of the battery swap point 100 perpendicular to the driving direction. The array-type battery swap station includes a first array unit 910 formed by two second charging devices 2 arranged opposite to each other perpendicular to the driving direction, and two vehicle loading platforms 100 are located between the two second charging devices 2;

Preferably, in the driving direction, a plurality of first array units 910 arranged in parallel form an array-type battery swap station; the first array units 910 are arranged in parallel along the driving direction with a regular layout, the vehicle battery swap process is more orderly, and more battery swap stations are provided, which can provide battery swap services for more vehicles.

Preferably, a spare lane 700 is provided between the vehicle loading platforms 100 of the two oppositely arranged second charging devices 2 in a direction perpendicular to the driving direction; in this embodiment, by providing the spare lane 700, sufficient space can be provided for vehicle passage, which is beneficial to the vehicle. Passing and waiting, the battery replacement of the vehicle in front will not affect the passage of the vehicle behind, improving the user experience.

Please refer to Figure 5, which is a fifth structural diagram of the battery swap station in this embodiment. As shown in Figure 5, this embodiment provides an array-type battery swap station, which can greatly save space through staggered arrangement, has a compact layout, and can set up more battery swap stations in a limited space. In addition, the vehicles parked on the vehicle loading platforms arranged front and back along the driving direction do not interfere with each other, and the vehicles pass smoothly.

In an optional embodiment, the electric vehicle on at least one battery swapping point can be charged by the corresponding second charging device 2. In a battery swapping station including multiple battery swapping points, one or more of the battery swapping points can be reused as charging points without setting up additional charging points, which improves the space utilization of the battery swapping station, and the workstations of battery swapping vehicles and direct charging vehicles can also be flexibly selected to avoid mutual influence.

The battery swap station of this embodiment is provided with a first charging device and a second charging device in the battery swap station. The first charging device is used to charge the battery swapping battery in the battery swap station, and the second charging device is used to charge the electric vehicle. Both the battery swapping of the battery swapping vehicle and the charging of the direct charging vehicle can be completed at the battery swap station. The charging resources of the battery swap station are distributed between the first charging device and the second charging device, which alleviates the waste or shortage of charging resources. At the same time, no matter what kind of vehicle the owner drives, he can replenish electricity at the battery swap station, which improves the owner's experience.

Example 2

Please refer to Figure 6, which is a first flow chart of the charging control method in this embodiment. Specifically, the charging control method is applied to the battery swap station in Example 1, and the charging control method includes:

S101, obtaining an output requirement of a second charging device;

S102: Configure the first charging device and/or the power system according to the output requirement so that the second charging device meets the output requirement.

Please refer to Fig. 7, which is a second flow chart of the charging control method in this embodiment. Specifically, preferably, the output demand includes the expected output power.

In an optional implementation, the second charging device is a charging pile, and the power of the charging pile is greater than 200 kW.

In an optional embodiment, the power supply system includes a battery replacement battery and/or an energy storage battery, and step S102 includes:

Control the battery replacement battery and/or energy storage battery to supply power to the second charging device.

Specifically, the second charging device may be powered by a battery replacement battery in a battery replacement station used to replace battery replacement vehicles, or a storage battery used for power regulation, thereby ensuring the power supply of the second charging device.

In an optional implementation, the power supply system includes a transformer, and the first charging device includes a bidirectional charging module; step S102 includes:

S1021. Determine whether the sum of the estimated output powers of the first charging device and the second charging device exceeds the rated power of the transformer;

S1022. When the sum of the predicted output powers of the first charging device and the second charging device exceeds the rated power of the transformer, control the battery replacement batteries corresponding to some or all of the two-way charging modules to discharge to the power supply system. Specifically, the user's electricity demand is not constant, but constantly changing. The charging demand is usually relatively stable, but there will be peak demand during certain periods. Although increasing the rated power of the transformer will improve the charging efficiency during peak power consumption, it will lead to higher construction and maintenance costs, and the proportion of time periods at peak power consumption is not large, and most of the time periods will lead to idleness and waste of charging resources. Therefore, in actual applications, the rated power of the transformer does not need to be greater than or equal to the sum of the maximum output powers of the first charging device and the second charging device, which reduces the requirements for the transformer specifications. When it is determined that the sum of the predicted output powers of the first charging device and the second charging device exceeds the rated power of the transformer, control some or all of the two-way charging modules. The corresponding battery swap discharges to the power supply system, which not only increases the output power of the power supply system, but also reduces the charging demand of the battery swap to meet the normal operation of the second charging device.

In an optional implementation, step S1022 includes:

S10221. Filter out the target battery to be discharged to the power system from the battery swapping batteries according to the preset SOC range. Specifically, the battery swapping batteries to be switched to the discharge state can be filtered out by the SOC value of the battery swapping batteries. For example, a battery swapping battery with an SOC value greater than 75% can be selected to be switched to the discharge state, which can prevent the battery swapping battery with a too low SOC value from being in an over-discharged state and causing battery loss.

In an optional implementation, step S1022 includes:

S10222. Obtain a power difference between the sum of the estimated output powers and the rated power of the transformer;

S10223. Determine the number of battery swap batteries and the discharge power to be discharged into the power system according to the power difference. Specifically, the number of battery swap batteries and the discharge power to be discharged into the power system are accurately determined according to the power difference between the sum of the expected output power and the rated power of the transformer, so as to reasonably configure the battery swap batteries to be discharged and avoid wasting charging resources.

In an optional embodiment, the first charging device further includes a unidirectional charging module, and the power system supplies power to the battery replacement battery or the second charging device through the unidirectional charging module; the battery replacement battery electrically connected to the bidirectional charging module is the first battery replacement battery, and the battery replacement battery electrically connected to the unidirectional charging module is the second battery replacement battery;

The method also includes:

Control the SOC value of the first battery exchange battery to be higher than the SOC value of the second battery exchange battery. Specifically, the first battery exchange battery can be discharged through the bidirectional charging module, and the second battery exchange battery cannot be discharged through the unidirectional charging module. Therefore, the SOC value of the first battery exchange battery is controlled to be higher than the SOC value of the second battery exchange battery, thereby ensuring sufficient discharge capacity to supply the second charging device, and preventing the battery exchange battery with a too low SOC value from being in an over-discharged state and causing battery loss.

In an optional implementation, step S102 further includes:

S1023. Reduce the charging power of the second battery-exchange battery or stop charging the second battery-exchange battery.

Specifically, for the second battery-exchange battery that cannot be discharged, the output power of the battery-exchange station can also be reduced by reducing the charging power or stopping charging to ensure the normal operation of the second charging equipment.

Please refer to Figure 8, which is the third flow chart of the charging control method in this embodiment. Specifically, in an optional implementation, the power system includes a transformer, and the first charging device includes a selection module and a unidirectional charging module. When the selection module is in a first state, the power system charges the battery replacement battery through the unidirectional charging module; when the selection module is in a second state, the power system supplies power to the second charging device through the unidirectional charging module; step S102 includes:

S1024. When the second charging device is working, the control selection module is switched to the second state. Specifically, for a battery swap station where the existing charging device is only equipped with a one-way charging module, a configuration selection module can be added. The selection module and the one-way charging module constitute a first charging device and are electrically connected to the second charging device, so that the selection module can select whether the power system provides power to the first charging device or to the second charging device. When the second charging device is working, the control selection module is switched to the second state.

The charging control method of this embodiment, by distributing the charging resources of the battery swap station between the first charging device and the second charging device in the above-mentioned battery swap station, alleviates the waste or shortage of charging resources, and ensures that the second charging device can reach the expected output power, thereby ensuring the charging time of the direct charging vehicle and improving the charging experience of the direct charging vehicle owner. Charging of direct-charging vehicles can be completed at the battery swap station. No matter what type of vehicle the owner drives, he can replenish electricity at the battery swap station, which improves the owner's user experience.
