Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a method, device and system for life cycle management of an electric vehicle battery pack. Background Art

[0002] With the clarification of the national carbon emission policy, the national and local governments have gradually increased the promotion of green energy vehicles. Major automobile manufacturers have also responded positively, gradually reducing the proportion of fuel vehicles in production and gradually transforming to produce new energy vehicles. At present, the mature new energy vehicle solution is electric vehicles, which use electricity as kinetic energy. In order to reduce the charging time of electric vehicles and solve the installation and use problems of charging piles, you can directly use a fully charged battery pack to replace a low-power battery pack to improve the user experience of electric vehicles. However, the mainstream battery leasing solutions on the market still have certain unreasonable aspects. For example, old batteries may be used to replace new batteries for newer vehicles, which is not cost-effective for lightly used vehicle owners, affecting the owner's experience and thus affecting the development of the electric vehicle industry. Summary of the invention

[0003] The problem solved by the present invention is to make the battery replacement strategy more reasonable and more in line with the needs of most customers, especially to improve the usage experience of light users.

[0004] In order to solve the above problems, the present invention provides a life cycle management method for an electric vehicle battery pack, which is applied to a battery swap station, comprising:

[0005] Obtaining a network access request from a user terminal, sending the network access request to a battery swap platform, allocating a battery pack to an electric vehicle matching the user terminal according to a usage agreement, and sending first battery information of the battery pack to the battery swap platform, wherein the battery swap platform is adapted to sign the usage agreement with the user terminal according to the network access request;

[0006] Acquire the battery replacement request of the user terminal and the second battery information of the battery pack, and when the first battery information and the second battery information simultaneously meet the battery replacement conditions, allocate a new battery pack for the electric vehicle according to the battery replacement request, and send the second battery information to the battery replacement platform, wherein the battery replacement platform is suitable for determining the user's power usage during the battery replacement and the real-time battery health of the battery pack according to the first battery information and the second battery information;

[0007] When the first battery information meets the scrapping condition, the battery pack used by the electric vehicle is recycled.

[0008] The life cycle management method of the electric vehicle battery pack described in the present invention determines the user's power usage during the battery replacement based on the first battery information when the user accesses the network and the second battery information when the user replaces the battery. Therefore, the user's power usage during the battery replacement can be used as the basis for charging, and charges are made according to the actual usage of the battery pack. At the same time, the cumulative power usage can be determined based on the user's power usage, and then the real-time battery health can be calculated based on the battery life cycle, so that the battery replacement strategy is more reasonable and more in line with the needs of most customers, especially effectively improving the experience of light users using the battery replacement service.

[0009] Optionally, when the first battery information and the second battery information meet the battery replacement condition, allocating a new battery pack to the electric vehicle according to the battery replacement request includes:

[0010] Obtain a judgment result of the battery swap platform on whether the first battery information meets the battery swap conditions, and determine whether to allocate a new battery pack for the electric vehicle based on the judgment result, wherein the battery swap platform is suitable for determining the battery health based on the first battery information, and judging whether the first battery information meets the battery swap conditions based on the difference between the battery health and a preset health.

[0011] The life cycle management method of the electric vehicle battery pack described in the present invention determines the battery health based on the first battery information stored in the battery replacement platform and then judges whether the battery replacement conditions are met. When the battery pack reaches the scrap standard, the battery replacement service is rejected, effectively ensuring the user's driving safety and usage experience.

[0012] Optionally, when the first battery information and the second battery information meet the battery replacement condition, allocating a new battery pack to the electric vehicle according to the battery replacement request further includes:

[0018] The user's power usage and the real-time battery health of the battery pack sent by the power exchange platform are obtained and displayed on the station display screen, wherein the method for the power exchange platform to determine the user's power usage and the real-time battery health of the battery pack includes:

[0019] When the battery pack is normally replaced, the power used by the user is determined as the difference in power of the battery pack;

[0020] When the battery pack is in an over-discharge state, the user's power usage is determined as the product of the difference in the battery pack power and the over-discharge calculation coefficient;

[0021] When the battery pack is in an overdue state, the power usage of the user is determined as the difference in the power of the battery packs, and the real-time battery health of the battery pack is determined as the difference between the battery health corresponding to the first battery information and the loss health, wherein the loss health is equal to the product of the battery replacement interval and the loss coefficient.

[0022] The life cycle management method of the electric vehicle battery pack described in the present invention determines the real-time battery health by accumulating the amount of electricity used, avoids unreasonable user behavior, and guides users to use the battery correctly, which is conducive to fully realizing the value of the battery and thus improving the user experience.

[0023] Optionally, the first battery information includes battery capacity; when the first battery information meets the scrapping condition, recycling the battery pack used by the electric vehicle at this time includes: when the battery capacity is lower than a preset ratio, determining that the first battery information meets the scrapping condition.

[0024] The life cycle management method of the electric vehicle battery pack described in the present invention determines whether the first battery information meets the scrapping condition according to the battery capacity and the size of the preset ratio, thereby preventing the battery with substandard performance from being used continuously.

[0025] Optionally, the life cycle management method of the electric vehicle battery pack also includes: obtaining a renewal request or a recycling request from the user terminal and sending it to the battery swap platform, wherein the battery swap platform is suitable for signing a new usage agreement with the user terminal based on the renewal request, and the battery swap platform is also suitable for determining the residual value of the battery pack used by the electric vehicle at this time based on the recycling request.

[0026] The life cycle management method of the electric vehicle battery pack described in the present invention, by obtaining the renewal request or recycling request of the user terminal and sending it to the battery replacement platform to complete the signing of a new usage agreement or the recycling of the battery pack, is conducive to increasing the user's options and thus improving the user experience.

[0027] Optionally, the life cycle management method of the electric vehicle battery pack also includes: when the real-time battery health meets the pre-scrap condition, obtaining the reminder information sent by the battery replacement platform and displaying it on the station display screen.

[0028] The life cycle management method of the electric vehicle battery pack described in the present invention ensures the continuity of the battery life cycle and effectively guarantees the user's driving safety and usage experience by setting a setting that when the real-time battery health meets the pre-scrap conditions, the reminder information sent by the battery replacement platform is obtained and displayed on the station-side display screen.

[0029] The present invention also provides a life cycle management device for an electric vehicle battery pack, which is applied to a battery swap station, comprising:

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a life cycle management method for an electric vehicle battery pack, which is applied to a battery swap station, comprising:

[0040] Obtaining a network access request from a user terminal, sending the network access request to a battery swap platform, allocating a battery pack to an electric vehicle matching the user terminal according to a usage agreement, and sending first battery information of the battery pack to the battery swap platform, wherein the battery swap platform is adapted to sign the usage agreement with the user terminal according to the network access request;

[0041] Acquire the battery replacement request of the user terminal and the second battery information of the battery pack, and when the first battery information and the second battery information simultaneously meet the battery replacement conditions, allocate a new battery pack for the electric vehicle according to the battery replacement request, and send the second battery information to the battery replacement platform, wherein the battery replacement platform is suitable for determining the power usage of the user during the battery replacement and the real-time battery health of the battery pack according to the first battery information and the second battery information;

[0042] When the first battery information meets the scrapping condition, the battery pack used by the electric vehicle is recycled.

[0043] Specifically, in this embodiment, the life cycle management method of the electric vehicle battery pack applied to the battery swap station includes: the battery swap station obtains the network access request of the user terminal, that is, the car owner purchases the battery service through the user terminal, the battery swap station sends the network access request to the battery swap platform, the battery swap platform is suitable for signing a usage agreement with the user terminal according to the network access request and sending it to the user terminal and the battery swap station, the battery swap station allocates the battery pack to the electric vehicle matching the user terminal according to the signed usage agreement, and sends the first battery information of the battery pack to the user data storage system of the battery swap platform.

[0044] The battery swap station obtains the battery swap request from the user terminal, that is, when the car owner uses the battery swap service, he uploads the battery swap request to the battery swap station and the battery swap platform through the user terminal. The battery swap platform obtains the user's battery health information, that is, the stored battery health, based on the first battery information stored in the user data storage system (if it is the first battery swap, the first battery information refers to the information stored when the battery pack is initially allocated; if it is not the first battery swap, the first battery information refers to the information stored after the last battery swap). If the battery pack reaches the scrap standard, the battery swap service will be rejected, and the car owner can choose to scrap and recycle it, or choose to renew the agreement with the platform and continue the battery swap service. If the battery pack does not reach the scrap standard, the battery swap station receives the battery pack previously used by the electric vehicle, and obtains the second battery information of the battery pack and sends it to the battery swap platform. The battery swap platform determines the user's power usage during this battery swap (for example, the power used between the user's access to the network and the first battery swap) and the real-time battery health of the battery pack based on the first battery information and the second battery information.

[0045] When the first battery information meets the scrapping conditions, in order to ensure the driving safety of users, the battery health condition meets the scrapping conditions, and the battery swap station can no longer provide battery swap services and recycle the battery pack used by the electric vehicle at this time. Subsequent battery swap platforms support paid recycling, and can also exchange for new batteries at a discount and renew the contract.

[0046] The following is an introduction to the relationship between the battery life cycle and the accumulated power storage.

[0047] Batteries produced by current battery technology have a certain life cycle. Under normal use, the life of the battery is closely related to the number of cycles, usage time, average charge and discharge power, charge and discharge depth, battery storage and operating temperature.

[0048] The storage capacity of a battery at different stages of its life cycle is different. When the storage capacity approaches or reaches a set critical point, it can be considered scrapped. The life of the battery can be converted into the storage capacity of the entire life cycle based on the number of charge and discharge times. Similarly, the corresponding node in the life cycle of the battery can also be calculated based on the cumulative storage capacity of the battery. This embodiment calculates the health of the battery pack owned by the same car owner when using the battery swap platform based on the cumulative power used, and uses the corresponding power calculation method to avoid unreasonable user behavior, guide users to use the battery correctly, and provide users with a fair, reasonable, safe and efficient user experience.

[0049] The existing mainstream battery rental plans all adopt a fixed fee, that is, the charging amount is used as the basis for charging. At the same time, the old battery may be used to replace the new battery of the newer vehicle. This is extremely uneconomical for light users (generally refers to users who do not often drive electric vehicles). Therefore, this embodiment charges according to the actual usage of the battery pack, which effectively improves the experience of light users in using the battery replacement service.

[0050] Combination Figure 2 As shown in the figure, the battery life cycle with the user terminal (such as a mobile phone) as the main body is described as follows: (1) The car owner purchases the battery service and signs a battery purchase agreement with the battery swap platform. (2) When the car owner uses the battery swap service, the battery swap platform matches a battery with the same health status based on the car owner's battery information. The user's battery pack usage is obtained, and the amount of power swapped is calculated and accumulated. (3) When the car owner's battery is about to be scrapped, the battery swap platform reminds the user to purchase a battery pack. In order to ensure the user's driving safety, when the battery health reaches the point of being scrapped, the battery swap service will no longer be provided. The battery swap platform supports paid recycling, and can also replace the battery at a discount and renew the contract. (4) When the car owner wants to withdraw from the agreement during use, the battery swap station can calculate the residual value of the battery based on the battery health status for paid recycling.

[0051] Combination Figure 3 As shown, the battery replacement steps are described as follows: (1) The car owner searches for a battery replacement station through the terminal application, parks the car at the designated location, and clicks on the battery replacement. (2) The battery replacement platform queries the car owner's information and obtains the user's battery health information. (3) If the battery reaches the scrap standard, the battery replacement service will be rejected. The car owner can choose to scrap and recycle it, or choose to renew the agreement with the platform to continue the battery replacement service. (4) If the battery does not reach the scrap standard, the battery replacement station receives the car owner's battery and obtains the battery information. If the battery information does not match the car owner's historical stored information, the battery replacement will be rejected. On the premise that the battery information matches, the car owner's battery pack with the same battery health is matched, and the power of the replaced battery pack is detected, and the information is passed to the battery replacement platform. (5) The battery replacement platform calculates the user's power according to the battery and user information uploaded by the battery replacement station according to the set rules, accumulates it to the total power consumption of the corresponding user, and stores the corresponding data.

[0052] In this embodiment, the user's power usage during the battery replacement is determined based on the first battery information when the user joins the network and the second battery information when the user replaces the battery. Therefore, the user's power usage during the battery replacement can be used as a basis for charging, and charges are made according to the actual usage of the battery pack. At the same time, the cumulative power usage can be determined based on the user's power usage, and then the real-time battery health can be calculated based on the battery life cycle, making the battery replacement strategy more reasonable and more in line with the needs of most customers, especially effectively improving the experience of light users using the battery replacement service.

[0053] Optionally, when the first battery information and the second battery information meet the battery replacement condition, allocating a new battery pack to the electric vehicle according to the battery replacement request includes:

[0054] Obtain a judgment result of the battery swap platform on whether the first battery information meets the battery swap conditions, and determine whether to allocate a new battery pack for the electric vehicle based on the judgment result, wherein the battery swap platform is suitable for determining the battery health based on the first battery information, and judging whether the first battery information meets the battery swap conditions based on the difference between the battery health and a preset health.

[0055] Specifically, in this embodiment, when the car owner uses the battery swap service, he uploads the battery swap request to the battery swap station and the battery swap platform through the user terminal. The battery swap platform obtains the user's battery health information, that is, the stored battery health, based on the first battery information stored in the user data storage system. If the battery pack reaches the scrap standard, it does not meet the battery swap conditions, and the battery swap service is rejected. The car owner can choose to scrap and recycle, or choose to renew the agreement with the platform and continue the battery swap service. If the battery pack does not reach the scrap standard, the battery swap station receives the battery pack previously used by the electric vehicle.

[0056] In this embodiment, the battery health is determined based on the first battery information stored in the battery exchange platform to determine whether the battery exchange conditions are met. When the battery pack reaches the scrap standard, the battery exchange service is refused, effectively ensuring the user's driving safety and usage experience.

[0057] Optionally, when the first battery information and the second battery information meet the battery replacement condition, allocating a new battery pack to the electric vehicle according to the battery replacement request further includes:

[0058] The first battery information and the second battery information are compared. If the first battery information and the second battery information match, a new battery pack is allocated to the electric vehicle. If the first battery information and the second battery information do not match, the battery replacement request is rejected.

[0059] Specifically, in this embodiment, since the batteries between different battery replacement platforms are not universal, it is necessary to compare the first battery information of the battery pack (which is the owner's historical storage information relative to the second battery information) and the second battery information. If they match, it means that the battery pack is the previous battery pack, and a new battery pack can be allocated to the electric vehicle. If they do not match, the battery replacement request is rejected to prevent accidents caused by incompatible battery pack charging.

[0060] In this embodiment, the first battery information and the second battery information of the battery pack are compared to prevent accidents caused by incompatibility when the battery swap station charges battery packs belonging to other battery swap platforms, thereby improving the safety of the battery swap station and the battery pack.

[0061] Optionally, when the first battery information and the second battery information match, the new battery pack having the same battery health as that in the first battery information is allocated to the electric vehicle.

[0062] Specifically, in this embodiment, when the first battery information and the second battery information match, a new battery pack with the same battery health as in the first battery information is allocated to the electric vehicle. Since the battery swap platform needs to reduce the time consumed by users when charging and swapping batteries by replacing battery packs, it is necessary to allocate a new battery pack with the same battery health as in the first battery information to the electric vehicle to ensure the continuity of the battery life cycle, effectively ensuring the user's driving safety and usage experience.

[0063] In this embodiment, by allocating a new battery pack with the same battery health as that in the first battery information to the electric vehicle, the continuity of the battery life cycle is ensured, thereby effectively guaranteeing the user's driving safety and usage experience.

[0064] Optionally, the first battery information and the second battery information both include battery pack power; after sending the second battery information to the battery replacement platform, the life cycle management method of the electric vehicle battery pack further includes:

[0065] The user's power usage and the real-time battery health of the battery pack sent by the power exchange platform are obtained and displayed on the station display screen, wherein the method for the power exchange platform to determine the user's power usage and the real-time battery health of the battery pack includes:

[0066] When the battery pack is normally replaced, the power used by the user is determined as the difference in power of the battery pack;

[0067] When the battery pack is in an over-discharge state, the user's power usage is determined as the product of the difference in the battery pack power and the over-discharge calculation coefficient;

[0068] When the battery pack is in an overdue state, the power usage of the user is determined as the difference in the power of the battery packs, and the real-time battery health of the battery pack is determined as the difference between the battery health corresponding to the first battery information and the loss health, wherein the loss health is equal to the product of the battery replacement interval and the loss coefficient.

[0069] Specifically, in this embodiment, an example is given to illustrate the calculation of the user's cumulative power according to actual usage. It is assumed that the battery pack capacity is a, the battery health is b, the battery replacement interval exceeds c days, the battery replacement overtime loss coefficient is δ, the over-discharge calculation coefficient is β, the owner's used power is d, the owner's used battery pack power is e, and the battery replacement interval is f. The explanation is as follows:

[0070] Case 1: Normal battery replacement, the amount of electricity used in this battery replacement is ae:

[0071] Case 2: The battery is in an over-discharge state when it is replaced. The amount of electricity for this replacement is (ae)*β

[0072] Case 3: The time since the user's last battery replacement is too long, and exceeds the longest interval specified in the agreement (more than c days). In this case, the battery health at the time of the battery replacement is bf*δ (f*δ is the loss health), the battery power replaced is ae, and the used power d can be calculated through the battery health and accumulated for this power.

[0073] In this embodiment, the real-time battery health is determined by accumulating the amount of power used, thereby avoiding unreasonable user behavior and guiding users to use the battery correctly, which is conducive to fully utilizing the battery value and thus improving the user experience.

[0074] Optionally, the first battery information includes battery capacity; when the first battery information meets the scrapping condition, recycling the battery pack used by the electric vehicle at this time includes: when the battery capacity is lower than a preset ratio, determining that the first battery information meets the scrapping condition.

[0075] Specifically, in this embodiment, whether the first battery information meets the scrapping condition is determined based on the battery capacity. Generally, the preset ratio can be 60% to 80%. Taking 70% as an example, generally, when the battery capacity is above 70%, the battery performance is still relatively stable, but when the battery capacity drops below 70%, the battery performance will decay rapidly. Therefore, the battery capacity dropping below 70% is set as the scrapping condition to prevent batteries that do not meet the performance standards from being used continuously.

[0076] In this embodiment, whether the first battery information meets the scrapping condition is determined according to the battery capacity and the preset ratio, so as to prevent the battery with substandard performance from being used continuously.

[0077] Optionally, the life cycle management method of the electric vehicle battery pack also includes: obtaining a renewal request or a recycling request from the user terminal and sending it to the battery swap platform, wherein the battery swap platform is suitable for signing a new usage agreement with the user terminal based on the renewal request, and the battery swap platform is also suitable for determining the residual value of the battery pack used by the electric vehicle at this time based on the recycling request.

[0078] Specifically, in this embodiment, if the battery pack reaches the scrap standard, the battery swap service will be rejected, and the owner can choose to scrap and recycle it, or choose to renew the agreement with the platform and continue the battery swap service. Here, the owner sends a renewal request or a recycling request to the battery swap station through the user terminal. The battery swap station forwards the request to the battery swap platform and signs a new usage agreement with the user terminal according to the renewal request, or determines the residual value of the battery pack used by the electric vehicle at this time according to the recycling request.

[0079] In this embodiment, by obtaining the renewal request or recycling request of the user terminal and sending it to the battery exchange platform to complete the signing of a new usage agreement or the recycling of the battery pack, it is helpful to increase the user's options and thus improve the user experience.

[0080] Optionally, the life cycle management method of the electric vehicle battery pack also includes: when the real-time battery health meets the pre-scrap condition, obtaining the reminder information sent by the battery replacement platform and displaying it on the station display screen.

[0081] Specifically, in this embodiment, when the owner's battery is about to be scrapped, the battery swap platform will send a reminder message to the display screen of the battery swap station and the user terminal display, reminding the user to purchase a battery pack. In order to ensure the user's driving safety, when the battery health condition reaches the scrap state, the battery swap service will no longer be provided. The battery swap platform supports paid recycling, and can also be discounted for replacement and contract renewal.

[0082] In this embodiment, when the real-time battery health meets the pre-scrapping conditions, the reminder information sent by the battery swap platform is obtained and displayed on the station display screen, thereby ensuring the continuity of the battery life cycle and effectively ensuring the user's driving safety and usage experience.

[0083] Another embodiment of the present invention provides a life cycle management device for an electric vehicle battery pack, which is applied to a battery swap station, comprising:

[0084] A network access module, used to obtain a network access request from a user terminal, send the network access request to a battery swap platform, allocate a battery pack to an electric vehicle matching the user terminal according to a usage agreement, and send first battery information of the battery pack to the battery swap platform, wherein the battery swap platform is suitable for signing the usage agreement with the user terminal according to the network access request;
