[0008] In order to make the above and other objects, features and advantages of the present invention more clearly and easily understood, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0009] 1 shows a battery exchange system 10 that is applied to supply batteries to electric vehicles, household appliances, industrial equipment, etc. For example, as shown in FIG. 1, the battery exchange system 10 includes nine exchange slots with batteries (indexes 0 to 8).

[0010] As shown in the embodiment of Figure 2, the battery exchange system 20 includes a control component 21, a power component 22, a detection component 23, an interface component 24, a plurality of slots 25, and an emergency power source 26, wherein the control component 21 is electrically connected to the power component 22, the detection component 23, the interface component 24, the slots 25, and the emergency power source 26, and the power component 22 is electrically connected to the detection component 23, the interface component 24, the slots 25, and / or the emergency power source 26, and each slot 25 can accommodate one or more batteries B, and the slots 25 may further include a component with an adsorption or stopper function for controlling the slot 25 to lock or unlock the battery B based on a signal transmitted from the control component 21.

[0011] 2 , the control component 21 includes a controller, a processor, an internal memory, and a hard disk, which can cooperate to execute operations required for the battery exchange process according to a predetermined logic or program. For example, the processor is electrically connected to the controller, the internal memory, and the hard disk, the controller controls the electronic modules in the power component 22, the detection component 23, and the interface component 24, the hard disk stores program code and / or related data, and the internal memory stores dynamic and / or static data. The processor in the control component 21 executes instructions to perform the method described in the present invention. In other embodiments, the desired functions can be implemented using modules appropriate for the battery exchange system 20 based on different design concepts. For example, the method described in the present invention can be implemented by an application-specific integrated circuit (ASIC) configured with built-in logic circuits (such as a state machine) that execute functions corresponding to the instructions.

[0012] As shown in the embodiment of Figure 2, the power components 22 include a relay, a charger, a power supply module, a breaker, etc., and the relay, charger, power supply module, and breaker are electrically connected to each other in an appropriate manner to convert AC power from a commercial power source into DC power or to supply DC power to battery B. For example, the power components 22 are electrically connected to the control components 21 and the interface components 24, and the control components 21 are arranged to control the power components 22 to charge at least one of the multiple batteries B in the slots 25.

[0013] The detection component 23 is for detecting at least one physical quantity. For example, the detection component 23 may include one or more sensors for detecting information such as temperature, water level, image, smoke, and fire. The detected information may be transmitted to the control component 21 via wired and / or wireless communication. The control component 21 may then perform a corresponding control flow or provide battery-related information based on the different information. For example, the temperature sensor is used to detect battery temperature information, and the control component 21 may determine whether each battery is usable or not based on the battery temperature information to prevent users from acquiring batteries that may overheat due to charging or malfunction. The water level sensor is used to provide water level detection data for the control component 21 to determine whether the location of the device is flooded or not. The image sensor detects images of the device's surroundings or during use, for use by the control component 21 for safety monitoring purposes. The smoke sensor provides smoke detection data for the control component 21 to determine whether the environment where the device is located is in a fire or smoke state. The fire sensor provides fire detection data for the control component 21 to determine whether the environment where the device is located is in a fire or smoke state.

[0014] The interface components 24 are electrically connected to the control components 21 and the power components 22 and may include modules such as a touch screen, a keyboard, an audio / video input / output device, and an audio / light pointing device for sending and receiving information required by the user to perform the battery replacement process. For example, the touch screen of the interactive interface can display battery information and be used by the user to select different options, the audio / light pointing device can assist the user in replacing the battery, the audio / video input device can be used to receive user instructions, the audio / video output device can be used to provide system-related information to the user, and the emergency power supply 26 can store power in advance to supply DC power to the battery replacement system 20 and / or battery B in the event of a power outage.

[0015] 3 has nine slots. In this embodiment, the electric vehicle user needs to exchange two batteries from the battery exchange system 30, and the battery exchange system 30 is configured to exchange two batteries from the battery group. TIFF2025121396000002.tif55 (where n is the total number of batteries in the battery exchange system 30, and m is the target number of battery exchange requests) can be supplied in whole or in part. For example, if there are batteries in all nine slots of the battery exchange system 30, n is equal to 9, the number of batteries to be exchanged, m, is equal to 2, and the battery group combinations that can be supplied by the battery exchange system 30 are 36 sets of dual battery indexes: (0,1), (0,2), (0,3), (0,4), (0,5), (0,6), (0,7), (0,8), (0,9), (10), (11), (12), (13), (14), (15), (16), (17), (18), (19), (20), (21), (22), (23), (24), (25), (26), (27), (28), (29), (30), (31), (32), (33), (34), (35), (36), (37), (38), (39), (40), (41), (42), (43), (44), (45), (46), (47), (48), (49), (50), (51), (52), (53), (54), (55), (55), (55), (56), (57), (58), (59), (60), (61), (62), (63), (64), (65), (66), (67), (68), (69), (70), (71), (72), (73), (74), (75), (76), (77), (78), (79), (80), (81), (82), (83), (84), (85), (86), (87), (88), (89), (90 ,2), (1,3), (1,4), (1,5), (1,6), (1,7), (1,8), (2,3), (2,4), (2,5), (2,6), (2,7), (2,8), (3,4), (3,5), (3,6), (3,7), (3,8), (4,5), (4,6), (4,7), (4,8), (5,6), (5,7), (5,8), (6,7), (6,8) and (7,8).

[0016] As shown in FIG. 3 , the battery exchange system 30 can further select an optimal candidate set by sorting all available battery groups based on conditions such as battery characteristic parameters and weighting factors. The battery exchange system 30 can select three battery characteristic parameters from “battery status,” “battery type,” “battery location,” “electrical quantity characteristics (charge state),” and “battery health” as comparison criteria. Furthermore, each battery characteristic parameter may be a value, a code, or a data format derived therefrom associated with a weighting factor. In this embodiment, the battery status is used to indicate whether the batteries in the battery group are exchangeable. The battery type is used to indicate whether the batteries in the battery group include the same type (e.g., version) of batteries. The battery location is used to indicate the numerical value of the distance between multiple batteries in the battery group, for example, by calculating the coordinate index of the batteries in the group to determine whether the distance between the batteries in the group is relatively small. The electrical quantity characteristics are used to indicate the state of charge of the batteries in the battery group, for example, whether the difference or average value of the state of charge of the batteries in the battery group is relatively large or small. The battery health is used to indicate the value of the health status of the batteries in this battery group, for example, by calculating two parameters (e.g., percentages) of the degree of health of the batteries in this battery group to determine whether the health status of the batteries in this battery group is good.

[0017] 3, the battery exchange system 30 can sort the 36 battery groups based on conditions such as the above characteristic parameters and associated weighting factors. An example of sorting is shown in FIG. 4, where the sorting results in the battery exchange system 30 are (2,3), (6,7), (0,7), (2,5), (0,5), (0,6), (0,7), (0,8), (1,2), etc., in descending order, with the most desirable battery group being (2,3). The battery exchange system 30 can display the battery group (2,3) in the interface component 24 as a replaceable battery group for the user.

[0018] 2 and 3, the battery exchange system 30 includes nine slots 25, and the battery exchange system 30 measures the battery B in each slot 25 using modules such as the detection component 23 to obtain battery characteristic parameters. The control component 21 uses the five characteristic parameters to select an optimal battery group (including two batteries) from among the four battery groups. In this embodiment, the weighting factors associated with the five characteristic parameters, "battery status," "battery type," "battery location," "electrical quantity characteristics," and "battery health," are 0.5, 0.25, 0.08, 0.09, and 0.08, respectively, and the sum of the weighting factors is 1. The battery group index of the first battery group is (0,7), and the values of the five characteristic parameters, including battery status, battery type, battery location (the distance of the battery in the battery exchange system), electrical quantity characteristics, and battery health, are 1, 1, 0.1, 0.5, and 0.7, respectively. The battery group index of the second battery group is (2,3), and the values of its five characteristic parameters, such as battery status, battery type, battery location, electrical quantity characteristics, and battery health, are 1, 1, 1, 1, and 0.8, respectively. The battery group index of the third battery group is (2,5), and the values of its five characteristic parameters, such as battery status, battery type, battery location, electrical quantity characteristics, and battery health, are 0, 0, 0.8, 0.8, and 0.8, respectively. The battery group index of the fourth battery group is (6,7), and the values of its five characteristic parameters, such as battery status, battery type, battery location, electrical quantity characteristics, and battery health, are 1, 1, 1, 0.75, and 1, respectively. The control component 21 can add the products of the characteristic parameters of the four battery groups and the associated weighting coefficients, and generate four scores based on the calculation results, for example, by rounding the calculation results to three decimal places as scores, such that the score of the first set of characteristic parameters is 0.859, the score of the second set of characteristic parameters is 0.984, the score of the third set of characteristic parameters is 0.2, and the score of the fourth set of characteristic parameters is 0.978.The control component 21 sorts the four scores in descending order. For example, the sorting results may be that the score of the second set of characteristic parameters is 0.984, the score of the fourth set of characteristic parameters is 0.978, the score of the first set of characteristic parameters is 0.859, and the score of the third set of characteristic parameters is 0.2. Because the score of the second set of characteristic parameters is the highest, the second set of battery groups is determined as the battery groups with the best scores in this example. In other embodiments, the battery exchange system 30 may use an appropriate algorithm (e.g., bubble sort) to directly select the battery group with the best score without sorting the battery groups. In other embodiments, the battery exchange system 30 may also use another appropriate algorithm to select battery groups. For example, the battery exchange system 30 may select one or more battery groups with a score higher than a preset score.

[0019] In some embodiments, the target number of battery exchange requests is equal to 2 (it may be a number greater than 2, but 2 is used as an example here), and the formula by which the control component 21 calculates the score for the battery group based on the five weighting factors is: S N =A N *W1 N +B N *W2 N +C N *W3 N +D N *W4 N +E N *W5 N is. (In the formula, S N is the score of the Nth battery group, where N is a positive integer. N is the battery status parameter of the Nth battery group, and the battery status parameter indicates whether two batteries in the Nth battery group can be replaced. B N is the battery type parameter of the Nth battery group, and the battery type parameter indicates whether two batteries in the Nth battery group have the same battery type. Nis the electrical quantity parameter of the Nth battery group, and the electrical quantity parameter indicates the difference in the state of charge of two batteries in the Nth battery group. D N is the battery health parameter of the Nth battery group, and the battery health parameter indicates the difference in battery health between two batteries in the Nth battery group. E N is a battery location parameter of the Nth battery group, and the battery location parameter indicates the interval between two batteries in the Nth battery group. N is 0.5, W2 N is 0.25, W3 N is 0.09, W4 N is 0.08, W5 N (is equal to 0.08.) This allows the battery to be selected based on the weighting coefficients of features related to the battery's borrowability status, version type, relative location, electrical quantity characteristics, and health status, and allows the battery to be selected using many battery features, thereby improving situations such as poor energy efficiency, short battery life, and inconvenient battery handling, and effectively reducing the user's poor experience and the adverse effects on the battery.

[0020] In one embodiment, if there are two or more battery groups with the same highest score, the battery exchange system 30 can randomly select one of the groups with the highest score to supply to the customer.

[0021] The battery exchange system 30 may also use other appropriate algorithms to select battery groups with the same score. In another embodiment, if there are two or more battery groups with the same highest score, the battery exchange system 30 may compare battery characteristic parameters, such as "electrical quantity characteristics," "battery health," and "battery location," in that order until only one battery group can be determined as the optimal battery group. For example, the control component 21 of the battery exchange system 30 may first calculate the total electrical quantity (e.g., expressed as a percentage) of the batteries in each of the two or more battery groups with the same score, and determine the battery group with the largest total electrical quantity characteristics as the optimal battery group. If the total electrical quantity of two or more battery groups is equal, the control component 21 may further calculate the total battery health (e.g., expressed as a percentage) of the batteries in the battery groups with the same total electrical quantity characteristics, and determine the battery group with the largest total battery health as the optimal battery group. If the sums of the battery health degrees of two or more battery groups are equal, the control component 21 further calculates the difference between the coordinate indexes of the battery locations of the battery groups with the same sums of the battery health degrees, and determines the battery group with the smallest difference between the coordinate indexes of the battery locations (shortest sum of intervals) of the battery groups with the same sums of the battery health degrees as the optimum battery group. In other embodiments, the order of comparing battery characteristic parameters such as electrical quantity characteristics, battery health degrees, and battery locations can be changed based on different design concepts.

[0022] In the example shown in FIG. 6 , with reference to FIGS. 2 and 3 , the battery exchange system 30 includes nine slots, and the battery exchange system 30 measures battery B in slot 25 using a module such as the detection component 23 to obtain battery characteristic parameters. The control component 21 selects two batteries from four battery groups using the four characteristic parameters. In this example, the weighting factors associated with the four characteristic parameters, “battery status,” “battery type,” “electrical quantity characteristics,” and “battery health,” are 0.5, 0.25, 0.15, and 0.1, respectively, and the sum of the weighting factors is 1. The battery group index of the first battery group is (0,7), and the values of the four characteristic parameters, “battery status,” “battery type,” “electrical quantity characteristics,” and “battery health,” are 1, 1, 0.5, and 0.7, respectively. The battery group index of the second battery group is (2,3), and the values of the four characteristic parameters, “battery status,” “battery type,” “electrical quantity characteristics,” and “battery health,” are 1, 1, 1, and 0.8, respectively. The battery group index of the third battery group is (2,5), and the values of the four characteristic parameters, i.e., battery status, battery type, electrical quantity characteristics, and battery health, are 0, 0, 0.8, and 0.8, respectively. The battery group index of the fourth battery group is (6,7), and the values of the four characteristic parameters, i.e., battery status, battery type, electrical quantity characteristics, and battery health, are 1, 1, 0.75, and 1, respectively. Then, the control component 21 can add the products of the four sets of battery characteristic parameters and the associated weighting coefficients to generate four scores for the four battery groups based on the calculation results, for example, the score of the first set of characteristic parameters is 0.895, the score of the second set of characteristic parameters is 0.98, the score of the third set of characteristic parameters is 0.2, and the score of the fourth set of characteristic parameters is 0.9625. Then, the control component 21 further sorts the four scores in descending order, and, for example, the sorting results are that the score of the second set of feature parameters is 0.98, the score of the fourth set of feature parameters is 0.9625, the score of the first set of feature parameters is 0.895, and the score of the third set of feature parameters is 0.2.Therefore, the control component 21 selects the second battery group with the highest score as the optimal battery group in this example. In another embodiment, without requiring a sorting process, the battery exchange system can further select the optimal battery group as the optimal battery group to supply to the user.

[0023] In some embodiments, the target number of battery exchange requests is equal to 2 (may be a number greater than 2, but 2 is used as an example here), and the formula by which the control component 21 calculates the score for each of the plurality of battery groups based on the four weighting factors is: S N =A N *W1 N +B N *W2 N +C N *W3 N +D N *W4 N is. (In the formula, S N is the score of the Nth battery group among the multiple battery groups, where N is a positive integer. N is the battery status parameter of the Nth battery group, and the battery status parameter indicates whether two batteries in the Nth battery group can be replaced. B N is the battery type parameter of the Nth battery group, and the battery type parameter indicates whether two batteries in the Nth battery group have the same battery type. N is the electrical quantity parameter of the Nth battery group, and the electrical quantity parameter indicates the difference in the state of charge of two batteries in the Nth battery group. D N is a battery health parameter of the Nth battery group, and the battery health parameter indicates the difference in battery health between two batteries in the Nth battery group. N is 0.5, W2 N is 0.25, W3 N is 0.15, W4 Nis equal to 0.1.) This allows the battery to be selected based on the weighting coefficients of the features related to the battery's borrowability status, version type, electrical quantity characteristics, and health, and the battery can be selected using appropriate battery features, thereby improving situations such as poor energy efficiency and short battery life, and effectively improving the user's poor experience and the adverse effects on the battery.

[0024] 6, if two or more battery groups have the same highest score, the battery exchange system may randomly select the battery group with the best score. In the above-described embodiment, the control component 21 may determine the best score as the highest score, but in other embodiments, the control component 21 may determine the best score as a low score or a score close to the target value.

[0025] The battery exchange system may perform other sorting processes, comparing the "electrical quantity characteristics" and "battery health" in this order, until only one battery group is determined as the optimal battery group. For example, first, the sum of the electrical quantities (e.g., expressed as a percentage) of the two batteries in each of two or more battery groups is calculated, and the battery group with the largest sum of the electrical quantity characteristics among the two or more battery groups is determined as the optimal battery group. If the sums of the electrical quantities of the two batteries in each of the two or more battery groups are equal, the sum of the battery health (e.g., expressed as a percentage) of the two batteries in each of the two or more battery groups is further calculated, and the battery group with the largest sum of one or more battery health values among the two or more battery groups is determined as the optimal battery group. In other embodiments, the order of comparing characteristic parameters such as the electrical quantity characteristics and battery health may be changed based on different design concepts.

[0026] In some embodiments, the control component 21 of the battery exchange system is further configured to cause the processor to execute instructions to: in response to two or more battery groups among the plurality of battery groups having the same highest score, select a battery group whose two batteries have the highest state-of-charge total score to supply the target number of batteries from the battery groups having the same highest score, and in response to two or more battery groups among the plurality of battery groups having the same highest state-of-charge total score, select a battery group whose two batteries have the highest battery health total score to supply the target number of batteries from the battery groups having the same highest state-of-charge total score. This allows for the selection of a more appropriate battery group based on conditions such as state-of-charge and health when the scores are the same, compared to a random selection method.

[0027] In the example shown in FIG. 7 , referring to FIGS. 2 and 3 , the battery exchange system 30 includes nine slots 25, and selects two batteries from four battery groups using three characteristic parameters. In this example, the weighting factors associated with the three characteristic parameters, “battery status,” “battery type,” and “electrical quantity characteristics,” are 0.5, 0.25, and 0.25, respectively, and the sum of the weighting factors is 1. The battery group index of the first battery group is (0,7), and the values of the three characteristic parameters, “battery status,” “battery type,” and “electrical quantity characteristics,” are 1, 1, and 0.6, respectively. The battery group index of the second battery group is (2,3), and the values of the three characteristic parameters, “battery status,” “battery type,” and “electrical quantity characteristics,” are 1, 1, and 0.8, respectively. The battery group index of the third battery group is (2,5), and the values of the three characteristic parameters, “battery status,” “battery type,” and “electrical quantity characteristics,” are 1, 0, and 0.8, respectively. The battery group index of the fourth battery group is (6,7), and the values of the three feature parameters, which are the battery state, battery type, and electrical quantity characteristics, are 0, 0, and 0.75, respectively. Then, the products of the four sets of feature parameters and the associated weighting coefficients are summed, and four scores are generated based on the calculation results. For example, the score of the first set of feature parameters is 0.9, the score of the second set of feature parameters is 0.95, the score of the third set of feature parameters is 0.95, and the score of the fourth set of feature parameters is 0.1875. The four scores are then further sorted in descending order. For example, the sorted results are 0.95 for the second set of feature parameters, 0.95 for the third set of feature parameters, 0.9 for the first set of feature parameters, and 0.1875 for the fourth set of feature parameters. Finally, because the scores of the second and third sets of feature parameters are the highest, one of the second and third battery groups is selected, and in this example, it is determined as the battery group with the optimal score. In another embodiment, the battery exchange system can select the battery group with the best score as the best battery group and provide it to the user.

[0028] In some embodiments, the target number of battery exchange requests is equal to 2 (may be a number greater than 2, but 2 is used as an example here), and the formula by which the control component 21 calculates the score for each of the plurality of battery groups based on the three weighting factors is: S N =A N *W1 N +B N *W2 N +C N *W3 N is. (In the formula, S N is the score of the Nth battery group among the multiple battery groups, where N is a positive integer. N is the battery status parameter of the Nth battery group, and the battery status parameter indicates whether two batteries in the Nth battery group can be replaced. B N is the battery type parameter of the Nth battery group, and the battery type parameter indicates whether two batteries in the Nth battery group have the same battery type. N is an electrical quantity parameter of the Nth battery group, and the electrical quantity parameter indicates the difference in the charging state of two batteries in the Nth battery group.) This allows a battery to be selected based on the weight coefficient of features related to the battery's borrowable state, version type, and electrical quantity characteristics, and a battery can be selected using fewer battery features, improving situations such as reduced energy efficiency and effectively reducing the user's poor experience and the adverse effects on the battery.

[0029] As shown in FIG. 7, the two sets of highest scores are the same (i.e., in this example, the scores of the second and third battery groups are 0.95 each), and in one embodiment, the battery exchange system can randomly select the second or third battery group as the battery group with the best score.

[0030] The battery exchange system can perform other sorting processes to compare the "electrical characteristics" until only one battery group from the second battery group and the third battery group is determined as the optimal battery group. For example, the sum (e.g., expressed as a percentage) of the electrical characteristics of the two batteries in the second battery group, 184 (=94+90), is greater than the sum of the electrical characteristics of the two batteries in the third battery group, 180 (=92+88). Finally, the second battery group is determined as the battery group with the optimal score.

[0031] In some embodiments, the control component of the battery exchange system is further configured to cause the processor to execute instructions to perform the step of, in response to two or more battery groups of the plurality of battery groups having the same highest score, selecting, from the battery groups having the same highest score, a battery group in which the two batteries have the highest total state-of-charge score to supply the target number of batteries, thereby enabling selection of a more appropriate battery group based on state-of-charge compared to a random selection method when the scores are the same.

[0032] 8 shows an embodiment of a battery supply method 80 of the battery exchange system 30. Referring to FIGS. 2 and 3, in the battery supply method 80, in step S0, the battery exchange system 30 receives a battery exchange request via the interface component 24, and the target number of the battery exchange request may be a system default value, or may be a target number (e.g., at least two) input by a user and received by the interface component 24. In step S1, the control component 21 groups the batteries B in the slots 25 based on the target number, for example, based on the number n of all or part of the batteries in the slots 25 and the target number m. TIFF2025121396000003.tif55 battery group combinations, each combination including a target number of batteries. In step S3, the control component 21 scores the battery groups based on the battery characteristic parameters and corresponding weighting factors, for example, calculates a score for each combination based on the multiple battery characteristic parameters and associated weighting factors. In step S5, a battery group is selected based on the scoring results, for example, the control component 21 selects a battery group with an optimal score from the multiple battery groups based on the scoring.

[0033] A large value for the feature parameter "battery condition" indicates that all batteries in the battery group are replaceable. A large value for the feature parameter "battery type" indicates that all batteries in the battery group are the same type (version). The feature parameter "battery position (distance between batteries)" indicates that the distance between battery groups in the battery swap system is relatively large or relatively small. The larger the feature parameter "electrical quantity characteristics," the higher the average electrical quantity characteristics of the battery group and the smaller the difference in electrical quantity characteristics (e.g., standard deviation) between batteries. The larger the feature parameter "battery health," the higher the battery health within the battery group.

[0034] The characteristic parameter "battery status" can determine a value based on "battery authentication," "battery and slot status," "battery voltage," and "battery exchange system status." For example, "battery authentication" indicates whether the battery is an authenticated battery. "battery and slot status" indicates whether there is an error in the battery and slot. "battery voltage" indicates whether the battery voltage is greater than a default threshold. "battery exchange system status" indicates whether there is any error related to the exchange operation in the battery exchange system.

[0035] The characteristic parameter "battery status" can further determine a value based on one or more of "battery health," "battery life," "battery temperature and time," and "false safety action mark." For example, "battery health" is for indicating whether the battery health is greater than a preset threshold. "battery life" is for indicating whether the battery is about to expire. "battery temperature and time" is for indicating whether the battery temperature is between a high temperature threshold and a low temperature threshold, and whether the return time is longer than a preset threshold. "false safety action mark" is for indicating whether an error mark with a logical value of "TRUE" exists.

[0036] The characteristic parameters may be binary values (e.g., 0 or 1) to indicate a binary state, such as interchangeability or type (version), of all batteries in the battery group. In other examples, each characteristic parameter may be a value ranging between 0 and 1 to indicate a degree of a particular characteristic, such as physical distance, electrical difference, or normalized state of health, of two batteries in the battery group. In other examples, the characteristic parameters may be other suitable positive or negative values.

[0037] The battery exchange system and battery supply method according to the above embodiment of the present invention divides the batteries in the battery exchange system into multiple battery groups based on a target number, calculates multiple scores for the multiple battery groups based on multiple weighting coefficients and multiple characteristic parameters, and selects an optimal battery group with an optimal score from the multiple battery groups based on the multiple scores to supply the target number of batteries. This makes it possible to supply the target number of batteries by easily selecting an appropriate battery group by comprehensively considering various battery conditions, and effectively alleviates the negative effects on batteries that are caused by supplying batteries based on the selected battery group, such as a poor user experience, reduced energy efficiency, shortened battery life, and inconvenient battery handling, rather than by selecting different batteries one after another.

[0038] Although the present invention has been disclosed by way of preferred embodiments, those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore the scope of protection of the present invention shall be governed by the contents defined in the appended claims.
