In addition, the central processing unit 50 is the user terminal 60 when the life capacity of the installed battery 20 is within the range of 20% to 30% or less than 20% of the total capacity of the battery through the battery status information detection unit 30. It can transmit a message that cannot be charged, exchanged, or rented a battery, or a message recommending the disposal of the battery.

Here, if the life capacity of the battery is within the range of 20% to 30%, the aging level of the battery is marked as 5 and transmitted to the user terminal 60, and if the life capacity of the battery is less than 20%, the aging level is marked as 6. It transmits to the user terminal 60.

That is, in the case of the installed battery 20 of the old level 5 and 6, it means the limit value for free charging, exchange, and sharing of the battery, and it is carried out at a charging density of 0.1 to 1.0 C-rate even if the battery is charged at a low speed if necessary. When charging or discharging, the battery should have a rest time of 6 to 24 hours, and in particular, it is recommended to maintain the SOC of the battery to be less than 95% to 99% of the total charging capacity of the battery.

In particular, when the battery life capacity received from the battery status information sensing device 30 is less than 20% of the total capacity of the battery, the central processing unit 50 may enable only the use of an incompletely charged battery. .

For reference, as the battery ages older, the separator separating the positive or negative electrode of the battery wears out, causing a short circuit or swelling in which the lattice structure of the negative electrode that stores lithium ions in the battery expands or collapses. The probability of occurrence of the phenomenon increases. This phenomenon occurs in large-capacity batteries as well as small-capacity batteries.

As described above, if appropriate measures are not applied according to the battery age, not only the capacity of the battery is deteriorated, but also serious ignition may occur. Therefore, the age limit of the battery must be set and managed in advance.

On the other hand, the battery sharing system 100 according to an embodiment of the present invention can be exchanged with the installed battery 20 of the electric transportation device 10 and the battery held by the charging station, the exchange station, and the rental station. For reference, one or more charging stations, exchange stations, and rental stations are set to have at least two spares of batteries, and it is recommended that the charging capacity of the batteries held at charging stations, exchange stations and rental stations be maintained at least 90% of the total capacity of the battery. According to this recommendation, it is possible to bring the battery to the specified potential difference range, thus preventing the battery from being overcharged in advance.

The central processing unit 50 uses the battery status information sensing device 30 to provide the user terminal 60 with the installed battery ( 20) exchange and sharing restriction message, and a message recommending disposal of the battery, and in particular, a message recommending that the charging capacity of the battery be kept below 95% to 99% are transmitted.

Referring to FIG. 3, the central processing unit 50 provides the battery state information sensing device 30 with a compensation standard for wear and tear when exchanging the battery of the electric transportation device 10 and the battery held at the charging station, exchange station, and rental station. Accordingly, it may be provided to change every hour according to the battery life capacity of the electric transport device 10 measured in real time.

Here, the central processing unit 50 may compare the life capacity of the installed battery 20 received in real time with a predetermined battery use criterion and transmit the received battery use recommendation message to the user terminal 60.

On the other hand, when the battery of the electric transportation device and the battery held by the charging station, the exchange station, and the rental station are exchanged, a wear and tear maintenance fee is incurred. The wear and tear maintenance charge refers to a cost incurred when the battery of the electric transport device and the battery held by the charging station, exchange station, and rental station are exchanged according to the battery age information of the electric transport device 10. More specifically, the wear and tear maintenance charge is the sum of the cost of compensation for the reduced battery life by using the battery for limited battery life, plus the cost of electricity and service used to charge the battery.

With reference to FIGS. 3 and 4, a wear and tear maintenance charge incurred when a battery and a charging station of an electric transportation device according to the battery age information, and a battery held by an exchange station and a rental station are exchanged will be described.

Here, the wear and tear maintenance charge is a cost (cost) that is determined according to the compensation standard and the billing standard, which is generated when the battery of the electric transportation device is exchanged with the owned battery.

First, referring to FIG. 3, the wear maintenance charge compensation standard is established by the central processing unit 50. The wear maintenance charge compensation standard is classified according to the age information of the installed battery 20 of the electric transportation device 10, that is, the age level.

Here, when the battery life capacity is 71% to 100% of the total capacity of the battery, the aging level of the battery is 1, in the case of 51% to 70%, the aging level of the battery is 2, and in the case of 41% to 50% In this case, the age level of the battery is defined as 3, and when the age of the battery is less than 40% or the age of the battery is more than 5 years, the age level of the battery is defined as 4.

Here, the year of the battery is set to 5 years, but the preset year of the battery may be changed according to the environment in which the battery is used, and the like, but is not limited thereto.

At this time, the central processing unit 50 determines the compensation standard for wear and tear generated when the battery 20 of the electric transportation device 10 and the battery held at the charging station, exchange station, and rental station are exchanged from the battery status information sensing device 30 in real time. Refer to the received battery status information. At this time, the wear maintenance fee compensation standard is set as the sum of the compensation cost due to the loss of battery life capacity of the electric transportation device, the compensation cost due to the year-old loss of the battery, the compensation cost according to the number of times of use of the battery, and the battery information sharing service cost.

In other words, the abrasion maintenance fee compensation standard is the compensation cost for the loss of battery life capacity, the compensation cost for the loss of battery age, the compensation cost for the number of times of battery use, and the battery information sharing service cost, respectively, depending on the battery life capacity of the electric transport device. It can be set individually and is charged to the user as the sum of their costs.

That is, the wear maintenance fee compensation standard is to compensate for the consumption (or loss) of the life capacity (SOH) of the battery as the user uses the battery held at the charging station, the exchange station, and the rental station.

For example, if the life capacity of the battery held by charging stations, exchanges, and rental stations is 100% and the life capacity of the battery is 99% after sharing and rental, the number of battery users who share and rent the owned battery will decrease by 1%. Financial compensation is provided to companies such as charging stations, exchange stations and rental stations for the life capacity. Accordingly, the charging station, the exchange station, and the rental station can make up for the consumption of the life capacity of the shared and rented battery.

As shown in FIG. 3, when the aging level of the battery is 1, the compensation cost due to the loss of the life capacity of the battery is about 0 to 5.1%, 5 to 10.1%, 10 to 15.1%, 15 to 20.1% of the battery cost. , 20 ~ 25.1%, 25 ~ 30.1%, which can be differentially set according to the battery life capacity, and the compensation cost due to battery year loss is about 0 ~ 0.5%, 0.6 ~ 1.0%, 1.1 ~ 1.5% of the battery year , 1.6 to 2.0%, 2.0 to 2.5%, and 2.6 to 3.0% can be set differently.

In addition, when the aging level of the battery is 1, the compensation cost based on the number of times the battery is used is a margin of up to 1% of the battery cost when charging 0 to 100 times, a margin of up to 2% of the battery cost when charging 201 to 400 times, and 401 to 600 times. When recharging, it can be differentially set at a maximum margin of 3% of the battery cost, and the cost of using the battery information sharing service can be set at a 1% margin compared to the maximum owned battery.

For example, when the installed battery 20 and the owned battery are exchanged, the compensation criterion for the wear and tear maintenance charge is, when the battery age level is 1 and the battery life capacity is 80%, 25% of the cost of the owned battery + electric transportation device It can be calculated as the sum of 2.5% of the cost of the battery of the vehicle + up to 3% of the cost of the battery of the electric vehicle + a margin of 1% of the cost of the battery held.

Here, when the aging level of the installed battery 20 is 4, the central processing unit 50 uses the user terminal 60 to limit the charging capacity of the installed battery 20, a message that recommends disposal of the battery, and a message that the battery cannot be shared. Can be transmitted. For reference, it is desirable to recommend disposal of batteries and non-shareable batteries to be used only by the user's own electric transportation device, or to perform a detailed inspection of the battery.

For reference, in the case of exchanging the installed battery 20 of the electric transportation device 10 with the battery held by the charging station, exchange station, and rental station in the battery sharing system 100, compensation for wear and tear maintenance fees according to the age information of the battery and aging level As for the standard, a wear and tear maintenance fee is calculated according to the age information and aging level of each battery, and the difference can be offset. In addition, the difference between the wear and tear maintenance charge may be paid to the side of the installed battery 20 and the retained battery, which is not at a high level of aging.

On the other hand, referring to FIG. 4, the abrasion maintenance fee claim standard is also established by the central processing unit 50, similar to the above-described wear maintenance fee compensation standard. Here, the wear maintenance charge compensation standard is classified according to the battery age level calculated by the battery age information of the electric transport device 10.

When the battery life capacity is 71% to 100% of the total capacity of the battery, the aging level of the battery is 1, and in the case of 51% to 70%, the aging level of the battery is 2. In addition, when the battery life capacity is 41% to 50% of the total capacity of the battery, the aging level of the battery is 3, in the case of 31% to 40%, the aging level of the battery is 4, and in the case of 20% to 30% The battery age level is set to 5. Moreover, if the battery life capacity is less than 20% of the total capacity of the battery or the battery is more than 5 years old, the age level of the battery is defined as 6.

The central processing unit 50 provides the stored battery to the user in a fully charged state when the installed battery 20 and the reserved battery are exchanged.

At this time, the criteria for claiming the wear and tear maintenance charge generated when the exchange is made refer to the battery status information received from the battery status information detection device, and the compensation cost due to the loss of battery life capacity, the electricity or service cost used to charge the retained battery, and the battery information. It can be set as the sum of the cost of shared services.

In this way, as the standards for claiming wear and tear maintenance charges are established, companies such as charging stations, exchange stations, and rental stations can make profits through services such as charging, exchanging, sharing, and lending their own batteries.

As shown in Fig. 4, when the battery age level is 2, the compensation cost according to the life capacity of the battery may be set at a maximum of 90% of the battery price compared to the life capacity loss, and the electricity cost or service cost used for charging is In the case of providing a battery that is fully charged with electricity/exchange/delivery costs, it can be set at a maximum of 2.5% of the battery price, and the battery information sharing service cost can be set at a maximum margin of 2.5% of the price of the battery of the electric transport device 10. have.

For example, if the battery life capacity is 35% and the battery aging level is 4, the criterion for charging the wear and tear maintenance charge is up to 85% of the battery price relative to the loss of life capacity of the battery + the price of the battery when a fully charged battery is provided. It can be set as the sum of up to 2.5% of the price plus a maximum of 2.5% margin of the battery's price.

For reference, in the case of exchanging the installed battery 20 and the owned battery in the battery sharing system 100, the wear and tear maintenance charge according to the age information and age level of the battery is determined according to the age information and age level of each battery. And the difference can be offset. In addition, the difference between the wear and tear maintenance charge may be paid to the side of the battery of the electric transportation device 10 and the battery that has a low aging level.

Meanwhile, referring to FIGS. 5 and 6, the battery sharing system 100 according to an exemplary embodiment of the present invention provides a user's Criteria for claiming indemnity may be established.

In other words, the central processing unit 50 determines the user's compensation charge based on the battery usage in case of damage to the replaced battery in the process of exchanging the installed battery 20 and the battery held at the charging station, exchange station, and rental station. It can be set according to the level of damage to the battery and the rate of damage to the battery.

First, as shown in FIG. 5, the user's compensation cost claim standard may vary according to the level of damage to the battery according to the level of the full room and the level of damage to the battery according to the full room ratio, and the user's full room level can be largely set in four categories according to the full room ratio. .

For example, the user's full room level 1 may be determined as a case where the user's full room ratio falls between 0% and 10%. When the user's room level is 1, the battery damage level includes damage to the battery such as the battery completely discharged according to the battery age information or the discharge of the battery whose cause is unknown.

User-wide level 2 can be determined as a case where the user's full-room ratio falls between 11% and 30%. When the user's fault level is 2, the battery damage level includes damage to the battery due to overspeed and stressful use of the electric transport device, or damage to the battery due to an accident with an error rate of less than 50%.

User-wide level 3 can be determined when the user's full-room ratio is between 31% and 40%. When the user's fault level is 3, the damage level includes damage to the battery due to an accident with an error rate of 50% or more.

User-wide room level 4 can be determined as a case where the user's full-room ratio is 41% or more. When the user's room level is 4, the level of damage to the battery is to deliberately disassemble and damage the battery, sell or dispose of the battery in an illegal/unauthorized condition, or use the battery subordinated to a charging station, exchange or rental station personally, or , Loss and theft of batteries due to false exchange and sharing of batteries of electric transportation devices.

As shown in FIG. 6, the user's fault is determined according to the user's fault level according to the battery usage in the user's compensation cost claim criteria, and compensation for the user according to the determined user's fault or not is requested.

For example, if a simple defect corresponding to the level 1 general fault occurs in the battery, if it is determined that a simple defect has occurred due to the incomplete behavior of the battery, the user may claim compensation of 1% to 10% of the price of the owned battery. If it is determined that the cause of the defect is in an impossible discharge state, the user can claim compensation of 5% to 10% of the price of the existing battery.

In addition, if the user's fault corresponding to the level 3 of the fault occurs in the battery, if it is determined that the fault was caused by more than 50% of the fault, the user can claim compensation up to 50% of the price of the existing battery. have.

For reference, the ratio of the compensation amount charged to the user in the user compensation cost claim standard may vary, but is not limited thereto.

On the other hand, when it is determined that the installed battery 20 is old or has a defective battery, charging, exchange, rental, and sharing of the installed battery 20 may be possible if the user additionally bears a cost.

Even if a defect does not occur in the installed battery 20, the charging station, the exchange station, and the rental station may refuse to exchange the battery, or the charging station, the exchange station, the rental station and the user with a history of visiting previously may be charged for battery compensation.

In addition, ownership of the installed battery 20 lies in the charging station, the exchange station and the rental station. However, when the battery is subordinate to the battery sharing system 100, the battery sharing system 100 has a certain stake.

On the other hand, in relation to the battery sharing system 100, all responsibility for the use and management of the battery is basically at the charging station, exchange station, and rental station that hold the battery, but the battery sharing system 100 has a stake as much as the dependent battery. If so, the responsibilities can be divided among users, charging stations, exchange stations and rental stations.

In addition, if the battery user in the battery sharing system 100, or at a charging station, exchange station, rental station, etc., does not tell or hide in advance about the deliberate performance degradation or damage of the owned battery, the user is responsible for all defects in the owned battery. An exception can be made from the liability to reimburse up to 50% of the price.

As described above, the battery sharing system 100 according to an embodiment of the present invention may exchange or lease and share the owned batteries between individuals and companies such as charging stations, exchange stations, and rental stations, or exchange batteries between companies and companies. Or, you can rent and share, and you can exchange, rent and share batteries between individuals and individuals.

First, referring to FIG. 7, a method of charging, exchanging, sharing, and lending a battery between individuals and companies will be briefly described.

First, in the method of sharing a battery between an individual and a company (S100), the battery status information of the battery 20 installed in the electric transportation device 10 is detected in real time through the battery status information detection device 30 (S110).

In this case, the battery status information detected in real time by the battery status information sensing device 30 may be transmitted to the central processing unit 50 in real time and stored.

Then, it is determined whether the battery 20 installed in the electric transportation device 10 is discharged (S120).

If it is determined that the installed battery 20 is in a discharged state, it is determined whether the recommended charging process stored in the central processing unit 50 in a preset state is possible (S130).

When the recommended charging process of the installed battery 20 can be performed, the battery can be charged or exchanged as necessary through a company such as a charging station, an exchange station, or a rental station, so that the vehicle can be operated normally (S132).

Conversely, when the recommended charging process of the installed battery 20 cannot be performed, the location of the charging station or exchange station designated as the user terminal 60 may be alerted to the driver in real time.

Here, the recommended charging process of the battery refers to a process of charging the battery at a normal speed without performing fast charging to the battery.

For example, in the case of simply performing a battery exchange service, the battery needs a fast charging process. On the other hand, in the case of sharing or lending a battery, the charging station, exchange station, rental station, etc. often have their own battery, so there is no need to perform a fast charging process when sharing and lending the battery.

In general, this is because, when high-speed charging is frequently performed during the charging process of the battery, the life of the battery is drastically reduced.

Accordingly, when a user of the installed battery 20 desires a service for sharing and lending a battery, it is not possible to attempt fast charging other than a charging process recommended by companies such as charging stations, exchange stations, and rental stations.

At this time, it is determined whether the user can move the electric transportation device 10 to a designated charging station or exchange station (S140).

When the electric transportation device 10 can be moved to a designated charging station or exchange station, the charging process and exchange service of the battery are normally performed (S142). When the battery charging or replacement is completed, the information on the normal operation and operation of the electric transport device 10 is recorded in the central processing unit 50, and the recorded operation information of the electric transport device 10 is recorded in the electric transport device 10. ) Is delivered to all subordinated companies as well as to users subordinated to that company.

At this time, if the user who uses the electric transportation device 10 is in a situation where the installed battery 20 cannot be replaced, the user may install the battery 20 at home or through a company such as another charging station, exchange station, rental station, etc. Performs self-charging.

On the other hand, only when the user does not self-charge the installed battery 20, the battery usage cost must be paid to the company according to the year information or usage of the battery.

On the other hand, when the electric transportation device 10 cannot go to the designated charging station, exchange station, and rental station, it is determined whether there is a problem other than discharge of the installed battery 20 (S150).

In other words, the electric transportation device 10 connected to the central processing unit 50 can self-diagnose or automatically determine whether or not other problems other than discharge of the battery as well as the status information of the installed battery 20 can be transmitted. have.

If it is determined that there is no problem other than battery discharge, it is determined whether the installed battery 20 of the electric transportation device 10 is compatible with the company's own battery, and external exchange of the installed battery is performed through a company other than the designated company. It can also be implemented (S142). In this case, when the battery is externally exchanged through a call from another company, the central processing unit 10 may charge the user an additional fee in addition to the reserved battery usage fee.

At this time, if it is determined that there is a problem other than the discharge of the battery, it is determined whether the user is at fault (S160).

First, if it is determined that other problems other than battery discharge have occurred due to the user's negligence, a penalty amount determined by the company is charged to the user.

Conversely, if the cause of the problem other than battery discharge is not the user's fault, a penalty determined by the company is imposed, and the battery is reused and replaced after the compatibility status of the installed battery and the owned battery is normalized. Through the electric transportation device 10 to be able to operate normally (S132).

For reference, when the user's fault is determined through the battery status information transmitted in real time to the central processing unit 50 according to a predetermined criterion while the electric transportation device 10 is running, compensation for the battery in which the problem occurs, and Compensation may be processed according to predetermined criteria. At this time, the user must pay the penalty amount recommended by the company.

First, with reference to FIG. 8, a brief description will be given of a battery charging, exchange, sharing, and rental service method (S200) between a company and a company in the battery sharing system 100 according to an embodiment of the present invention.

First, when the electric transportation device 10 enters a new company, the battery status information detection device 30 recognizes the battery 20 of the electric transportation device 10 that entered the company, and the battery recognized in real time. Detects status information, life, defect or year information of (210).

At this time, it is determined whether or not there is a defect in the battery other than the discharge or discharge of the installed battery 20 by using the battery status information detection device 30 (S220).

If it is determined that there are no defects other than discharge of the battery, the manufacturing date and year information of the installed battery is determined (S226).

In the central processing unit 50, a new company that has determined the manufacturing date and year information of the installed battery 20 transmits the exchange fact and information of the installed battery 20 to the existing company. For reference, the fact of exchange of the installed battery 20 and information may be automatically transmitted through the central processing unit 50.

If the user does not want to exchange batteries between companies, the charging process may be performed by other companies. In this case, the user pays the battery charging cost to another company, and the addition of the battery age and usage information generated by charging may be stored in the central processing unit 50 in real time.

Here, it is determined whether the new company and the existing company intend to exchange the battery (S230). At this time, essential information such as usage information, manufacturing year, year, etc. of the batteries exchanged with each other is shared without falsehood. Legal action may be taken if false information is intentionally shared with respect to batteries intended to be exchanged with each other. For this reason, existing companies are given the right to refuse to exchange between companies regardless of the condition of the battery being exchanged.

On the other hand, if mutual agreement is reached between the companies, compensation is provided according to the manufacturing year, month, usage, and year of the battery. For example, when calculated from the manufacturing year and month of the battery, a company that exchanges a battery with a relatively small battery life according to the remaining life capacity of the battery may be compensated according to a compensation standard predetermined by the central processing unit 50. . These contents can be applied to all companies in the process of exchanging batteries between companies.

Then, after checking whether the electric transport device 10 is operating normally, the operation of the electric transport device is performed (S250).

On the other hand, if the mutual agreement between the companies is not achieved, the user is confirmed to charge the battery through another external company (S232).

If the user agrees to charge the battery through an external company, the battery is charged through an external company.

In this process, the cost incurred by battery replacement is paid to an external company (S236).

Here, if the user does not agree to charge the battery through an external company, the battery can be exchanged through an existing company. In other words, the battery sharing system 100 calls an existing company to perform external exchange of the battery, and the cost for calling the company and replacing the battery may be set to the user.

On the other hand, when a defect occurs in a battery that has been replaced during a charging process through an external company, it is tracked as the time when the battery defect occurs. In this process, it is determined whether the user's fault is caused by the battery defect while automatically checking and checking how the electric transportation device 10 has been operated (S234).

If it is determined that it is not the user's fault, the external company can exchange a new battery for a defective battery, and the external company can claim compensation for the replacement of the battery from the existing company.

In this case, the external company may additionally charge a separate fee to the existing company. In particular, the battery sharing system 100 provides information related to an external company by calculating the profit or loss of a defective battery, and the external company may claim the corresponding compensation to the existing company.

After the user exchanges the battery usage information after replacing the installed battery 20, the user checks whether the electric transportation device 10 is operating normally, and then performs the operation.

In addition, with reference to FIG. 9, a brief description will be given of a method (S300) of exchanging batteries or rental and sharing services between individuals and individuals.

First, the state information of the battery 20 installed in the electric transport device 10 is detected in real time through the battery state information sensing device 30 (S310).

At this time, it is desirable to recognize all the states of the individual batteries 20 participating in the battery exchange.

Then, through the central processing unit 50, the individual's intention to exchange and share the battery is determined.

At this time, if it is determined that the individual is willing to exchange and share the battery, a subordinate company of the battery to be exchanged by the individual is identified (S320).

Here, if a subordinate company of the battery to be shared is identified, it is possible to determine whether individual batteries are compatible.

When it is determined that the company to which the individual battery is dependent is the same, the information of the battery is transmitted to the central processing unit 20 (S322).

If it is determined that the companies to which the individual batteries depend are not the same, it is determined whether or not the battery to be exchanged is discharged and discharged through the battery status information sensing device 30 (S330).

At this time, if it is determined that the battery to be replaced has no defects other than discharge, status information including the manufacturing year, year, and information of the battery to be exchanged or shared is determined (S332).

If, among the batteries of other companies to which the central processing unit 50 is not subordinated, information on the manufacturing date and year of the battery is identified, actual information on the exchange and sharing of the battery is transmitted to each other to exchange and share the battery. The doctor is determined (S334).

However, only when a license agreement for simplifying the exchange and sharing of batteries has been concluded between certain companies, the determination of the intention to exchange the battery may be automatically processed by the central processing unit 50. In this case, it is possible to charge a certain service cost according to the degree of battery exchange by the individual user who exchanges the battery, and it is limited to a designated place where battery exchange can be stably performed.

On the other hand, when a battery exchange of a non-subordinate company is authorized by each company, a battery with a relatively low life may be rented according to the first calculated battery's manufacturing year, usage, and year information. In that case, the user may pay an amount equal to the difference through compensation between companies.

For reference, at least one company may have the right to refuse to exchange and share batteries for other companies that are not subordinated. When the exchange of batteries between companies is rejected by the central processing unit 50, the exchange/sharing of batteries between individuals is prohibited (S350).

In this case, only charged batteries can be provided from existing companies. Then, the user may be charged an additional charge including external replacement of the battery from the existing company, and the step of exchanging usage information after external replacement of the battery is performed.

On the other hand, when the battery to be exchanged/shared has a problem other than discharge, it is tracked to the point in time when the problem of the battery occurred, and whether or not the user's fault occurred (S340).

Here, if it is determined that the problem of the battery is not the user's fault, the existing company is called through the central processing unit 50 to receive and receive a replacement battery (S342).

In principle, the replacement battery delivered by the called existing company should be replaced with a fully charged battery. Accordingly, the central processing unit 50 may charge the user a total sum of the battery charging cost + transportation cost due to external exchange + labor cost due to delivery.

Conversely, if it is determined that the problem of the battery is caused by the user's fault, exchange/sharing of batteries between individuals is prohibited through the central processing unit 50 (S350).

A user who is prohibited from exchanging and sharing batteries between individuals may claim compensation between the individual and the company (S360). At this time, penalties are set differently depending on whether the battery is defective, but the problem of compensation with the company can be handled in real time by an automated server (not shown) and is mediated by the battery sharing system 100.

As long as the problem of compensation between the individual and the company is normally terminated, a fully charged battery can be exchanged or rented from an existing company. For reference, when the compensation processing is delayed in the battery sharing system 100, the compensation problem may be solved later through a record stored in the central processing unit 50.

It checks whether the electric transport device 10 operates normally and performs normal operation (S370).

By the above configuration and the method according to the configuration, the battery sharing system 100 according to an embodiment of the present invention charges, exchanges, rents and shares batteries between individuals and companies, between companies and companies, and between individuals and individuals. In this way, it is possible to maximize the operating efficiency of the electric transportation device 10.

In particular, as it takes a long time to charge the battery of the electric transport device 10, the performance of the battery due to rapid charging is deteriorated, and the limitation of mobility of the electric transport device for charging the battery and waste due to the rest process are reduced. There is an effect that can be.

As described above, in one embodiment of the present invention, specific matters such as specific components, etc., and limited embodiments and drawings have been described, but this is provided only to aid in a more general understanding of the present invention. It is not limited, and various modifications and variations are possible from these descriptions by those of ordinary skill in the field to which the present invention pertains. Accordingly, the spirit of the present invention is limited to the described embodiments and should not be defined, and all things equivalent or equivalent to the claims as well as the claims to be described later belong to the scope of the inventive concept.
