[0024] Example 1

[0025] According to an embodiment of the present invention, a method for replacing the battery of a vehicle in a battery swapping station is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0026] Figure 1 This is a flowchart of a method for replacing a vehicle battery at a battery swapping station according to an embodiment of the present invention. The method may include the following steps:

[0027] Step S101: Obtain the number of vehicles with batteries to be replaced at the battery swapping station and the replacement time required for the vehicle's battery to be replaced.

[0028] In the technical solution provided by step S101 of the present invention, the number of vehicles with batteries to be replaced in the battery swapping station can be the number of vehicles queuing in the battery swapping station, and the replacement time required to replace the battery of a vehicle can be the estimated battery swapping time of a single vehicle. By using a visual recognition system, the number of vehicles queuing in the battery swapping station can be identified, and by using a battery swapping time monitoring system, the estimated battery swapping time of a single vehicle can be calculated, thereby obtaining the number of vehicles with batteries to be replaced in the battery swapping station and the replacement time required to replace the battery of a vehicle.

[0029] Optionally, a visual recognition system and a battery swapping time monitoring system can be installed in the smart battery swapping station. The visual recognition system can be used to identify the number of vehicles queuing in the battery swapping station and feed back the identified number of vehicles queuing to the application platform. The battery swapping time monitoring system can be used to monitor the time when the vehicle starts swapping the battery and the time when the vehicle finishes swapping the battery, and thereby calculate the time required for the vehicle to complete the battery swapping.

[0030] Step S102: Based on the number of vehicles and the replacement time, determine the waiting time required to replace the battery of the vehicle that is the last to have its battery replaced.

[0031] In the technical solution provided by step S102 of the present invention, the waiting time required for replacing the battery of the last vehicle among multiple vehicles can be the total time for queuing to replace the battery.

[0032] Optionally, after obtaining the number of vehicles with batteries to be replaced at the battery swapping station and the replacement time required for replacing the batteries of the vehicles, the waiting time required for replacing the battery of the last vehicle among the multiple vehicles can be determined based on the number of vehicles and the replacement time. For example, the total waiting time for battery swapping can be determined based on the number of vehicles queuing at the battery swapping station and the estimated completion time of battery swapping for a single vehicle.

[0033] Optionally, the number of vehicles can be represented by N, the replacement time can be represented by T, and the waiting time can be represented by ΣN*T. This is only an example and is not specifically limited.

[0034] Step S103: Based on the waiting time, determine the battery replacement strategy for multiple vehicles at the battery swapping station.

[0035] In the technical solution provided by step S103 of the present invention, the battery replacement strategy for multiple vehicles in the battery swapping station can be a charging reference strategy determined based on queuing information.

[0036] Optionally, after determining the waiting time required to replace the battery of the last vehicle to have its battery replaced based on the number of vehicles and the replacement time, a battery replacement strategy for multiple vehicles at the battery swapping station can be determined by judging the relationship between the waiting time and a time threshold. For example, a charging reference strategy can be determined by judging the relationship between the waiting time and the time threshold. This is only an example and is not specifically limited.

[0037] Optionally, the battery swapping strategy for multiple vehicles at a battery swapping station can be used to adjust the charging rate, adjust the upper limit of charging capacity, and replenish electrical energy.

[0038] Step S104: Replace the batteries in multiple vehicles based on the replacement strategy.

[0039] In the technical solution provided by step S104 of the present invention, after determining the battery replacement strategy for multiple vehicles in the battery swapping station based on the waiting time, the batteries of multiple vehicles can be replaced separately according to the determined replacement strategy. For example, according to the current charging reference strategy, the batteries of the vehicles queuing in the battery swapping station can be replaced separately.

[0040] Optionally, if the determined replacement strategy is the first replacement strategy, the charging rate is increased, the upper limit of charging capacity is reduced, and additional energy is added. In this case, the batteries of the vehicles queuing at the battery swapping station are replaced respectively. If the determined replacement strategy is the second replacement strategy, the charging rate is increased, the upper limit of charging capacity is reduced, and additional energy is added. In this case, the batteries of the vehicles queuing at the battery swapping station are replaced respectively. If the determined replacement strategy is the third replacement strategy, the standard charging rate and the upper limit of charging capacity are maintained. In this case, the batteries of the vehicles queuing at the battery swapping station are replaced respectively. If the determined replacement strategy is the fourth replacement strategy, the charging rate is reduced and the upper limit of charging capacity is maintained. In this case, the batteries of the vehicles queuing at the battery swapping station are replaced respectively.

[0041] In steps S101 to S104 of this application, the number of vehicles with batteries to be replaced in the battery swapping station and the replacement time required for replacing the batteries of the vehicles are obtained. The product between the number of vehicles and the replacement time is obtained, thereby determining the waiting time required for replacing the battery of the last vehicle among the multiple vehicles. By judging the relationship between the waiting time and the time threshold, the replacement strategy for replacing the batteries of multiple vehicles in the battery swapping station is determined. According to the determined replacement strategy, the batteries of multiple vehicles are replaced respectively, thereby achieving the purpose of changing the charging strategy in real time. This solves the technical problem of difficulty in quickly swapping batteries for vehicles under various operating conditions and achieves the technical effect of quickly swapping batteries for vehicles under various operating conditions.

[0042] The method described in this embodiment will be further described below.

[0043] As an optional embodiment, step S102, based on the number of multiple vehicles and the replacement time, determines the waiting time required to replace the battery of the vehicle that is last to have its battery replaced among the multiple vehicles, including: obtaining the product between the number of multiple vehicles and the replacement time; and determining the product as the waiting time.

[0044] In this embodiment, after obtaining the number of vehicles with batteries to be replaced in the battery swapping station and the replacement time required for replacing the batteries of the vehicles, the number of vehicles and the replacement time are multiplied, and the product between the number of vehicles and the replacement time is obtained. The product between the number of vehicles and the replacement time is determined as the waiting time required for the last vehicle to have its battery replaced. Here, the number of vehicles can be represented by N, the replacement time can be represented by T, and the waiting time can be represented by ΣN*T. This is only an example and is not specifically limited.

[0045] Optionally, the product of the number of vehicles queuing in the battery swapping station and the estimated battery swapping time of a single vehicle is calculated, and the product between the number of vehicles queuing in the battery swapping station and the estimated battery swapping time of a single vehicle is obtained. The product between the number of vehicles queuing in the battery swapping station and the estimated battery swapping time of a single vehicle is determined as the current total queuing battery swapping time.

[0046] As an optional embodiment, step S103, based on the waiting time, determines a battery replacement strategy for multiple vehicles at the battery swapping station, including: determining a first replacement strategy in response to the waiting time exceeding a first time threshold; determining a second replacement strategy in response to the waiting time exceeding a second time threshold but not exceeding the first time threshold; determining a third replacement strategy in response to the waiting time exceeding a third time threshold but not exceeding the second time threshold; and determining a fourth replacement strategy in response to the waiting time not exceeding the third time threshold.

[0047] In this embodiment, the first duration threshold can be 40 minutes, and the first replacement strategy can be used to represent increasing the charging rate of the battery, reducing the upper limit of the charging capacity, and replenishing the battery. The second duration threshold can be 20 minutes, and the second replacement strategy can be used to represent increasing the charging rate of the battery, reducing the upper limit of the charging capacity, and replenishing the battery. The third duration threshold can be 10 minutes, and the third replacement strategy can be used to represent maintaining the standard charging rate of the battery and maintaining the upper limit of the charging capacity. The fourth replacement strategy can be used to represent reducing the charging rate of the battery and maintaining the upper limit of the charging capacity. These are only examples and are not specifically limited.

[0048] Optionally, after determining the waiting time required to replace the battery of the last vehicle to have its battery replaced based on the number of vehicles and the replacement time, a replacement strategy for replacing batteries of multiple vehicles at the battery swapping station can be determined by judging the relationship between the waiting time and the time threshold. If the waiting time exceeds the first time threshold, the replacement strategy is determined as the first replacement strategy, and the charging rate is increased, the upper limit of the charging capacity is reduced, and the charging capacity is supplemented. If the waiting time exceeds the second time threshold but does not exceed the first time threshold, the replacement strategy is determined as the second replacement strategy, and the charging rate is increased, the upper limit of the charging capacity is reduced, and the charging capacity is supplemented. If the waiting time exceeds the third time threshold but does not exceed the second time threshold, the replacement strategy is determined as the third replacement strategy, and the standard charging rate and the upper limit of the charging capacity are maintained. If the waiting time does not exceed the third time threshold, the replacement strategy is determined as the fourth replacement strategy, and the charging rate is reduced and the upper limit of the charging capacity is maintained.

[0049] Optionally, if the first time threshold is 40 minutes, the second time threshold is 20 minutes, and the third time threshold is 10 minutes, and the waiting time is 45 minutes, then the waiting time exceeds the first time threshold, the replacement strategy is determined to be the first replacement strategy, and the charging rate is increased, the upper limit of the charging capacity is reduced, and the power is replenished; if the waiting time is 30 minutes, then the waiting time exceeds the second time threshold but does not exceed the first time threshold, the replacement strategy is determined to be the second replacement strategy, and the charging rate is increased, the upper limit of the charging capacity is reduced, and the power is replenished; if the waiting time is 15 minutes, then the waiting time exceeds the third time threshold but does not exceed the second time threshold, the replacement strategy is determined to be the third replacement strategy, and the standard charging rate and the upper limit of the charging capacity are maintained; if the waiting time is 8 minutes, then the waiting time does not exceed the third time threshold, the replacement strategy is determined to be the fourth replacement strategy, and the charging rate is reduced and the upper limit of the charging capacity is maintained.

[0050] As an optional embodiment, in step S103, while determining the battery replacement strategy for multiple vehicles at the battery swapping station based on the waiting time, the method further includes: detecting the current environment of the battery swapping station and obtaining the detection result; in response to the detection result indicating that the weather level of the current environment has reached the weather level threshold, activating the hot air blower in the battery swapping station, and determining the sum of the time for defreezing by the hot air blower and the replacement time as the replacement time required for replacing the vehicle battery in the current environment; in response to the detection result indicating that the weather level of the current environment has not reached the weather level threshold, disabling the hot air blower.

[0051] In this embodiment, the detection results can be used to characterize whether the current weather level has reached the weather level threshold. The weather level can be used to indicate the severity of the current weather. For example, the detection results can be used to indicate whether rain or snow has occurred in the current environment. The hot air blower can be used to heat the air and blow it towards the connection between the vehicle and the backup energy storage battery to prevent the battery swapping mechanism from jamming due to freezing rain or other reasons. The battery swapping mechanism may include plugs, sockets and / or guide rails, etc. This is only an example and is not specifically limited.

[0052] Optionally, while determining the battery replacement strategy for multiple vehicles at the battery swapping station based on the waiting time, the current environment of the battery swapping station is detected, and the detection results are analyzed. If the detection result indicates that the weather level of the current environment has reached the weather level threshold, the hot air blower in the battery swapping station is activated to heat the air and blow it towards the connection between the vehicle and the backup energy storage battery. The sum of the time taken to thaw the ice through the hot air blower and the replacement time is determined as the replacement time required to replace the vehicle battery under the current environment. If the detection result indicates that the weather level of the current environment has not reached the weather level threshold, the hot air blower is disabled, and there is no need to heat the air.

[0053] Optionally, an environmental monitoring device can be used to monitor the current environment of the battery swapping station and obtain the monitoring results. The environmental monitoring device may include temperature sensors, rain sensors, and rain and snow sensors, etc. This is only an example and is not specifically limited.

[0054] As an optional embodiment, before obtaining the number of vehicles with batteries to be replaced in the battery swapping station and the replacement time required to replace the batteries of the vehicles in step S101, the method further includes: detecting the number of vehicles and the replacement time in response to battery replacement requests sent by other vehicles besides the vehicles with batteries to be replaced in the battery swapping station.

[0055] In this embodiment, before obtaining the number of vehicles with batteries to be replaced at the battery swapping station and the replacement time required for each vehicle's battery, if other vehicles besides those with batteries to be replaced at the battery swapping station find that their own battery is low, then the vehicle sends a battery replacement request on the application. The battery swapping station can then receive the battery replacement request sent by the vehicle through the application signal receiving system. In response to the battery replacement request sent by the vehicle, the battery swapping station detects the number of vehicles and the replacement time through the data detection system.

[0056] Optionally, the data detection system can communicate with the vision recognition system and the battery swapping time monitoring system. When the data detection system is used at the battery swapping station, it can send control commands to the vision recognition system and the battery swapping time monitoring system to control the vision recognition system to identify the number of vehicles with batteries to be replaced at the battery swapping station and to control the battery swapping time monitoring system to calculate the replacement time required to replace the batteries of the vehicles.

[0057] As an optional embodiment, in step S102, after determining the waiting time required to replace the battery of the vehicle that will have its battery replaced last among the multiple vehicles based on the number of vehicles and the replacement time, the method further includes: sending the waiting time to the application.

[0058] In this embodiment, after determining the waiting time required to replace the battery of the vehicle that will have its battery replaced last among the multiple vehicles based on the number of vehicles and the replacement time, the waiting time required to replace the battery of the vehicle that will have its battery replaced last among the multiple vehicles is sent to the application terminal, so that other vehicles that need to replace their batteries can view the waiting time required to replace the battery at the battery swapping station in real time on the application terminal.

[0059] Optionally, the application can be a mobile application (APP) or an in-vehicle APP. The application can communicate with the battery swapping station. For example, the battery swapping station can send the waiting time to the application through a visual recognition system. The application can then receive the waiting time sent by the battery swapping station and determine whether to send a battery replacement request to the battery swapping station based on the waiting time.

[0060] This embodiment obtains the number of vehicles with batteries to be replaced in the battery swapping station and the replacement time required to replace the batteries of the vehicles. It obtains the product between the number of vehicles and the replacement time, thereby determining the waiting time required to replace the battery of the last vehicle among the multiple vehicles. By judging the relationship between the waiting time and the time threshold, it determines the replacement strategy for replacing the batteries of multiple vehicles in the battery swapping station. According to the determined replacement strategy, the batteries of multiple vehicles are replaced respectively, thereby solving the technical problem of difficulty in quickly swapping batteries for vehicles under various operating conditions, and achieving the technical effect of quickly swapping batteries for vehicles under various operating conditions.

[0061] Example 2

[0062] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0063] Current battery swapping stations typically employ a fixed charging strategy for replacing batteries in vehicles. However, this fixed strategy cannot adapt to the number of vehicles queuing at the station, making it difficult to alleviate the excessive charging pressure during peak swapping periods. This results in the technical challenge of enabling rapid battery swapping for vehicles under various operating conditions. Therefore, a new method for battery swapping at stations is needed to ensure rapid battery swapping for vehicles under diverse operating conditions.

[0064] One related technology discloses an electric vehicle battery swapping method, comprising: a user sending a battery swapping reservation request for the electric vehicle to a battery swapping station; the battery swapping station sending a battery swapping request to the electric vehicle based on the received reservation request; the electric vehicle outputting a battery swapping process interface based on the battery swapping request and disabling the electric vehicle's high-voltage charging function; acquiring the electric vehicle's battery swapping information and sending the information to the battery swapping station; the battery swapping station performing a battery swapping operation on the electric vehicle's power battery based on the information; and sending a battery swapping completion message to the electric vehicle when the operation is complete. However, this electric vehicle battery swapping method only outputs a battery swapping process interface based on the battery swapping request and disables the electric vehicle's high-voltage charging function. It cannot adjust the charging strategy in real time according to the number of vehicles queuing at the battery swapping station, thus making it difficult to guarantee rapid battery swapping for vehicles under various operating conditions.

[0065] However, this invention proposes a method for replacing batteries at an intelligent battery swapping station. By employing different scheduling strategies under different queuing conditions, the method swaps batteries for vehicles queuing at the station, achieving the goal of real-time changes in charging strategies. This solves the technical problem of difficulty in rapidly swapping batteries for vehicles under various operating conditions and realizes the technical effect of rapidly swapping batteries for vehicles under various operating conditions.

[0066] Figure 2 This is a schematic diagram of a smart charging dispatching battery swapping station system according to an embodiment of the present invention, as shown below. Figure 2As shown, the intelligent charging and dispatching battery swapping station system may include: an energy storage and photovoltaic device 201, a backup energy storage battery 202, a battery swapping station 203, adjustable chargers 2041 to 204n, a temperature-controlled battery charging chamber 2051 to 205n, an automatic battery swapping platform 206, a visual recognition system 207, and an APP signal receiving system 208. The energy storage and photovoltaic device 201 can be used to convert solar energy into backup energy and charge and discharge the energy storage device according to peak and off-peak electricity prices. The adjustable chargers 2041 to 204n can be used for… The appropriate charging mode is adopted according to the different types and conditions of the backup energy storage battery 202. The temperature equalization battery charging compartments 2051 to 205n can be used to control the temperature and quickly restore the replaced backup energy storage battery 202. The automatic battery swapping platform 206 can be used to complete the automatic plugging and unplugging operation between the vehicle and the backup energy storage battery 202. The vision recognition system 207 can be used to identify the number of vehicles in the queue and feed it back to the platform. The APP signal receiving system 208 can be used to receive the battery swapping reservation request sent by the user through the mobile APP.

[0067] Optionally, the smart charging dispatching battery swapping station system may also include a hot air blower, which can be used to heat the air and blow it towards the connection between the vehicle and the backup energy storage battery, thereby preventing the battery swapping mechanism from jamming due to freezing rain or other reasons.

[0068] Optionally, after detecting that a vehicle requiring battery swapping has entered the automatic battery swapping platform, the hot air blower is activated, and the temperature and airflow of the hot air blower are adjusted according to the ambient temperature to blow hot air toward the battery swapping mechanism where the vehicle connects to the backup energy storage battery, such as blowing it toward the plug, socket, and / or rail, to maintain a suitable temperature and dryness. After the battery swapping is completed, the hot air blower is turned off, and the vehicle is disconnected from the backup energy storage battery, allowing the vehicle to leave the automatic battery swapping platform.

[0069] Optionally, the connection method of this intelligent charging dispatching battery swapping station system can be achieved in the following way: The battery swapping station is equipped with multiple uniformly heated battery charging compartments, each equipped with an adjustable charger. Each compartment can freely load and unload batteries via an automatic battery swapping platform. The automatic battery swapping platform is matched with a vehicle chassis, and a hot air blower is provided for the battery swapping mechanism. On the battery swapping access road of the station, a visual recognition system can monitor the queuing situation of vehicles, count the number of vehicles in the queue, and transmit the statistical data back to the station. The station is equipped with a Tbox signal and APP signal receiving system, as well as energy storage and photovoltaic devices.

[0070] Optionally, the following steps can be performed using energy storage and photovoltaic devices: Step 1: During the day, solar energy is converted into electrical energy using photovoltaic panels, and the electrical energy is either stored in the energy storage device or directly transmitted to the grid according to the grid's demand and price; Step 2: At night or on rainy days, the electrical energy in the energy storage device is used to charge the replaced backup energy storage battery, or cheap electricity is purchased from the grid during off-peak hours to charge the replaced backup energy storage battery, thereby effectively improving the energy utilization rate and economic benefits of the smart battery swapping station.

[0071] Optionally, during peak battery swapping periods or peak pricing periods, the electrical energy stored in the energy storage device can be used to provide services for vehicles that need battery swapping, thereby effectively improving the energy utilization rate and economic benefits of smart battery swapping stations.

[0072] Optionally, the swapped battery can be charged by using multiple separate temperature-equalizing battery charging compartments and adjustable chargers. The swapped-out spare energy storage battery is sent into the temperature-equalizing battery charging compartment and its current remaining capacity and temperature are detected. Each temperature-equalizing battery charging compartment can adjust its temperature state according to the battery temperature so that the battery can quickly recover to the optimal charging temperature. The adjustable charger can use different currents to charge the battery according to the strategy.

[0073] Optionally, based on the remaining capacity and temperature of the backup battery, a suitable temperature control mode is selected, such as a cooling mode, a heating mode, or a constant temperature mode. After reaching the optimal charging temperature, the backup energy storage battery is connected to the adjustable charger, and a suitable charging mode is selected based on the type and state of the backup energy storage battery, such as a constant current mode, a constant voltage mode, or a pulse mode. After charging is completed, the backup energy storage battery is disconnected from the adjustable charger and removed from the temperature-controlled battery charging compartment, awaiting replacement in the vehicle.

[0074] Figure 3 This is a flowchart of a user-side battery swapping method according to an embodiment of the present invention, such as... Figure 3 As shown, the battery swapping method at the user end may include the following steps:

[0075] Step S301: Enter the battery swap request in the APP.

[0076] After entering the battery swap request in the APP, the user proceeds to step S302, where the APP provides feedback on the current queuing time of each battery swap station, and the user goes to the target battery swap station according to their needs.

[0077] The app displays the current queue times for each battery swapping station. After the user goes to the target battery swapping station according to their needs, they proceed to step S303, confirm arrival at the battery swapping station, click to confirm battery swapping, and join the queue.

[0078] After confirming arrival at the battery swapping station, clicking to confirm the battery swap, and joining the queue, proceed to step S304, where you can confirm the battery's charging status (State of Charge, or SOC) on the app.

[0079] After confirming the SOC on the APP, proceed to step S305, wait and complete the battery swap.

[0080] Optionally, the SOC can be confirmed on the APP through the following steps: depending on the queuing situation at the battery swapping station, the station will send the SOC selection to the user. If the battery swapping time is long, the user will be asked to choose whether to fully charge. If full charging is chosen, the queuing time will be long. If other SOCs are needed, the user can submit them on the APP as required.

[0081] Figure 4 This is a flowchart of a battery swapping method at a battery swapping station according to an embodiment of the present invention, such as... Figure 4 As shown, the battery swapping method at this battery swapping station may include the following steps:

[0082] Step S401: Analyze the number of vehicles in the queue based on visual recognition.

[0083] After analyzing the number of vehicles in the queue based on visual recognition, step S402 is entered. Based on the number of vehicles in the queue N and the battery swapping time per vehicle T, the total queuing time ΣN*T is calculated (that is, the queuing time of the last vehicle is ΣN*T), and the total queuing time is sent to the user's APP.

[0084] After sending the total queuing time to the user's APP, proceed to step S403, select the appropriate charging strategy based on the total queuing time, and start the backup power supply according to the charging strategy.

[0085] After activating the backup power supply according to the charging strategy, proceed to step S404 to determine whether the user needs to activate the heater. If the user needs to activate the heater, proceed to steps S405 and S406 to activate the heater and include the time for the heater to defrost in the battery swapping time T. Swap the battery for the vehicle as needed and continue repeating the above steps. If the user does not need to activate the heater, proceed to step S406 to swap the battery for the vehicle as needed and continue repeating the above steps.

[0086] Optionally, an applicable charging strategy can be selected based on the total queuing time, where the charging strategy can be as shown in Table 1 below:

[0087] Table 1. Charging Allocation Reference Strategy

[0088] Current total battery swapping queue time ΣN*T Standard charging rate Charging SOC External power supply Extreme queue time ≥40 minutes 1.2C 80％ External power supply Long queue of ≥20 minutes 1.1C 90％ External power supply Queuing is required for ≥10 minutes 1.0C 100％ No energy replenishment <10 minutes is normal 0.8C 100％ No energy replenishment

[0089] Optionally, by adjusting the charging rate, the SOC threshold for charging completion, and the external power replenishment status, the relationship between vehicle queuing and replenishment can be satisfied, achieving an optimal balance between battery swapping users, the power grid, and the battery swapping station. If there are many vehicles in the queue (T>10min), the battery swapping station can prioritize providing services to vehicles that need urgent battery swapping and lower the SOC threshold for charging completion (e.g., from 100% to 85%), and notify the user via the app. If the user agrees, the battery swap can be completed quickly. If the user needs a fully charged battery, the user can choose not to agree and continue waiting in the queue. If there are few vehicles in the queue (T<10min), the battery swapping station can provide balanced services to all vehicles, and the SOC threshold for charging completion is 100%.

[0090] In this embodiment, the battery swapping station system is constructed by setting up energy storage and photovoltaic devices, backup energy storage batteries, battery swapping stations, adjustable chargers, temperature-controlled battery charging chambers, automatic battery swapping platforms, visual recognition systems, and APP signal receiving systems. At the same time, the battery swapping station system can match a charging strategy suitable for the current situation based on the current total queuing time, and notify the user of information such as the charging completion SOC threshold under the charging strategy through the APP. This solves the technical problem of difficulty in quickly swapping batteries for vehicles under various operating conditions, and achieves the technical effect of quickly swapping batteries for vehicles under various operating conditions.
