[0046] Example 1

[0047] Figure 1 This is a flowchart of a vehicle battery switching test method according to Embodiment 1 of the present invention. This embodiment is applicable to the switching of battery packs in autonomous vehicles. The method can be executed by a vehicle battery switching test device, which can be implemented in hardware and / or software and can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0048] The technical solution of this embodiment can be executed by a terminal device. This embodiment can be applied to autonomous vehicles. Since fast battery swapping is used in autonomous vehicles and enables switching of battery packs during driving, it is necessary to ensure the vehicle's continuous and stable operation within a set period. Therefore, the stability of its battery switching requires long-term and thorough testing to improve product performance.

[0049] S110, a test scenario for configuring autonomous vehicles.

[0050] The test scenario includes a vehicle controller, a charge / discharge test cabinet, and at least two battery packs. The vehicle controller, as the vehicle's controller, is used to demonstrate the vehicle's control during testing. The charge / discharge cabinet serves as a load during battery discharge and a charger during charging. The charge / discharge test cabinet demonstrates the charge / discharge power characteristics under various operating conditions. In this embodiment, the autonomous vehicle is equipped with at least two battery packs. Simulating the vehicle's connection method, the batteries are connected, with low-voltage connections for power supply and control, and high-voltage connections for the load. In this embodiment, at least two battery packs can be placed in a high-low temperature chamber, thus configuring the test scenario for the autonomous vehicle.

[0051] In this embodiment, optionally, at least two battery packs may include a running battery pack and at least one spare battery pack, and the running battery pack and at least one spare battery pack are connected in parallel and then connected to the charge-discharge test cabinet.

[0052] Specifically, in this embodiment, multiple batteries can be placed in a laboratory incubator. The positive and negative terminals of the batteries are led out using wire harnesses, and wire harnesses of the same polarity are connected in parallel. Then, the positive terminal of the parallel wire harness is connected to the positive terminal of the charge-discharge test cabinet, and the negative terminal is connected to the negative terminal of the charge-discharge test cabinet.

[0053] This embodiment can connect the vehicle controller, charging and discharging test cabinet, and at least two battery packs to configure a test scenario for autonomous vehicles, so as to test the switching of battery packs.

[0054] In this embodiment, optionally, configuring the test scenario for the autonomous vehicle includes: connecting the wake-up power supply of the vehicle controller to the experimental power supply; controlling the vehicle to collect the charging and discharging power characteristics of the battery pack under various operating conditions; and inputting the charging and discharging power characteristics into the charging and discharging test cabinet to configure the test scenario for each operating condition.

[0055] The wake-up power supply for the vehicle controller can be used to wake up the vehicle controller. In this embodiment, the wake-up power supply for the vehicle controller can be connected to an experimental power supply so that the experimental power supply can wake up the vehicle controller. For example, in this embodiment, the positive and negative terminals of the wake-up power supply for the vehicle controller can be led out and connected to the positive and negative terminals of a 12V DC power supply in the laboratory.

[0056] In this embodiment, at least two battery packs are placed in a laboratory incubator. The CAN-H and CAN-L communication signals of the battery packs are led out using wiring harnesses, and harnesses with the same signal are connected in parallel to the CAN-H and CAN-L pins of the vehicle controller. In this embodiment, the positive terminal of the internal controller wake-up power supply of each battery pack can be connected to the high-level output pin of the vehicle controller. When the battery needs to be woken up, the vehicle controller outputs a high level to wake up the internal controller of that battery, thereby controlling the charging and discharging of the battery pack. For example, in this embodiment, at least two battery packs can be placed in a laboratory incubator, and the negative terminals of the internal controller wake-up power supplies of all battery packs can be connected in parallel to the negative terminal of a 12V DC power supply in the laboratory. This embodiment simulates various operating load conditions in the laboratory, reducing the environmental requirements for battery testing.

[0057] In this embodiment, the optional operating conditions include uphill operating conditions, downhill operating conditions, wet and slippery road surface operating conditions, rapid acceleration operating conditions, emergency braking operating conditions, continuous high-speed operating conditions, and continuous limp operating conditions.

[0058] This embodiment can also control the vehicle to collect the charging and discharging power characteristics of the battery pack under various operating conditions, including uphill, downhill, slippery road, rapid acceleration, emergency braking, continuous high-speed, and continuous limp-walking. Specifically, in this embodiment, the charging and discharging power characteristics are input into the charging and discharging test cabinet by recording the charging and discharging power characteristic curves of the vehicle under different operating conditions and then programming these characteristics into the cabinet. In this embodiment, it can be set that after the charging and discharging test cabinet is turned on and the program is entered, the power curves for each operating condition are executed sequentially in a loop. The loop period can also be set according to experimental requirements. Through this setting, the battery can simulate the charging and discharging power characteristics under various operating conditions, and multiple operating conditions and scenarios can be cycled, thus providing valuable reference for developing different operating strategies for the vehicle.

[0059] In this embodiment, the vehicle controller's wake-up power supply is connected to the experimental power supply to control the vehicle to collect the charging and discharging power characteristics of the battery pack under various operating conditions. The collected charging and discharging power characteristics under various operating conditions are then input into the charging and discharging test cabinet through software programming to configure the test scenarios for each operating condition.

[0060] In this embodiment, the charging and discharging power characteristics under various operating conditions can be collected to record the charging and discharging power characteristics of the vehicle under different operating conditions. These characteristics can then be input into the charging and discharging test cabinet to configure test scenarios under different operating conditions, making the test data more accurate.

[0061] S120. Based on the received operating condition cycle command, test the current battery pack in the test scenario to obtain the test information of the current battery pack.

[0062] The operating condition cycle command can be understood as an instruction that executes various operating conditions cyclically. Test information can include battery pack charging and discharging information, as well as test data such as the current battery status.

[0063] In this embodiment, the current battery pack can be tested in a pre-configured test scenario using the received operating condition cycle command to obtain test data such as the charging and discharging information of the current battery pack and the current state information of the battery.

[0064] Specifically, in this embodiment, based on the received operating condition cycle command, the charge and discharge test cabinet can be used as a load when the battery pack is discharging and a charger when it is charging. Based on the public cycle command, the charging and discharging power characteristics under each operating condition are output in a cycle. By connecting the low-voltage control terminal of the battery pack to the vehicle controller, the current battery pack charging and discharging information and the current battery status information can be collected.

[0065] This embodiment can start the charging and discharging test cabinet and the vehicle controller power supply, use a computer to connect to the CAN transceiver, send the command to enter the working condition cycle to the communication CAN network of the vehicle controller, and control the charging and discharging cabinet to enter the charging and discharging power simulation program of different scenarios through the human-machine interaction display screen of the charging and discharging cabinet.

[0066] Furthermore, in this embodiment, a program can be preset in the vehicle controller. When the command to enter the operating cycle is received, the vehicle controller wakes up one of the battery packs and sends a command to discharge the battery. Then, the vehicle controller wakes up the other battery and sends a command to switch the battery pack. The switching cycle between batteries can be set according to the experimental requirements. In this embodiment, by controlling the cycle period of the operating cycle command, the frequency of switching the battery pack under different test scenarios can also be realized.

[0067] S130, Generate switching instructions based on test information.

[0068] The switching command carries information about the target battery pack. The switching command can be understood as switching the battery pack. In this embodiment, the current battery pack can be switched to the target battery pack using the switching command. The switching command can be generated based on the remaining capacity of the vehicle and the battery's operating status information.

[0069] In this embodiment, the battery pack switching command can be generated by collecting the battery pack test information, and multiple battery packs can be switched without interrupting the high voltage.

[0070] S140. Switch from the current battery pack to the target battery pack according to the switching command.

[0071] The target battery pack can be determined based on the real-time detected status of the battery pack. In this embodiment, the current battery pack can be switched to the target battery pack according to a switching command generated from the test command.

[0072] S150. Take the target battery pack as the new current battery pack and return to execute the operation of testing the current battery pack in the test scenario based on the received operating condition cycle instruction until the test end condition is met, and obtain test information of at least two battery packs.

[0073] The test termination condition can be a pre-set condition; for example, in this embodiment, the test termination condition can be set to a test duration of 24 hours. In this embodiment, the test termination condition can be set according to actual needs. In this embodiment, the switched target battery pack can be used as the new current battery pack, and the operation of testing the current battery pack in the test scenario based on the received operating condition cycle instruction can be returned until the test termination condition is met, so as to obtain test information of at least two battery packs.

[0074] Specifically, the vehicle controller in this embodiment can collect various experimental parameters of the battery pack in real time, such as current, remaining capacity, temperature difference, differential pressure, auxiliary component temperature, cell temperature rise, load power, ambient temperature, and ambient temperature change rate. Then, based on the built-in algorithm (the algorithm can refer to GB / T38031, GB / T36276, GB / T31467), it calculates various battery performance evaluation indicators such as energy efficiency, energy retention rate, energy recovery rate, battery internal resistance, and cycle life under different operating conditions and environments, and directly sends out the test information.

[0075] The technical solution of this invention involves configuring a test scenario for an autonomous vehicle. The test scenario includes a vehicle controller, a charging / discharging test cabinet, and at least two battery packs. Based on received operating condition cycle instructions, the current battery pack is tested within the test scenario to obtain test information. A switching instruction is generated based on the test information. The current battery pack is switched to a target battery pack according to the switching instruction. The target battery pack is then used as the new current battery pack, and the process of testing the current battery pack within the test scenario based on the received operating condition cycle instructions is repeated until the test termination condition is met, thus obtaining test information for at least two battery packs. This technical solution can obtain test data under various operating conditions, compress the test cycle, and improve the accuracy of the test data.

[0076] Example 2

[0077] Figure 2This is a flowchart of a vehicle battery switching test method according to Embodiment 2 of the present invention. This embodiment is an optimization based on the above embodiment. Specifically, the optimization includes: configuring a test scenario for an autonomous vehicle, including: acquiring a temperature range and / or humidity range; configuring a test scenario with set operating conditions based on the temperature range and / or humidity range. Figure 2 As shown, the method includes:

[0078] S210, Obtain the temperature range and / or humidity range.

[0079] The temperature range can be preset. In this embodiment, a preset temperature range or humidity range can be obtained, or a preset temperature range and humidity range can be obtained.

[0080] S220, configure test scenarios based on temperature range and / or humidity range.

[0081] The set working conditions can be pre-defined working condition test scenarios.

[0082] In this embodiment, test scenarios with set operating conditions can be configured based on the acquired temperature and / or humidity ranges. Specifically, in this embodiment, the temperature of the chamber can be set to cycle within a certain range at a certain period, thereby enabling the testing of battery pack switching under different seasons and different operating conditions.

[0083] In this embodiment, the humidity of the temperature chamber can be set to cycle within a certain range and periodically, thereby enabling the testing of battery pack switching under different temperature and operating conditions in inland or coastal cities. This embodiment can also input temperature variation patterns into the high and low temperature chamber based on the seasonal temperature changes in different usage regions, thus enabling the testing of battery output performance at different temperatures and providing reference data for the vehicle's driving range, operating conditions, and environment.

[0084] This embodiment allows the battery to be cycled in the laboratory to simulate the temperatures of spring, summer, autumn and winter, enabling the battery to be tested for operating temperatures throughout the year in the laboratory. This reduces the difficulty of testing, improves the accuracy of test results, and provides more precise data support for battery cycle life.

[0085] S230. Based on the received operating condition cycle command, test the current battery pack in the test scenario to obtain the test information of the current battery pack.

[0086] S240, Generate switching instructions based on test information.

[0087] The switching command carries information about the target battery pack.

[0088] In this embodiment, optionally, generating a switching instruction based on test information includes: if the test information includes that the remaining power of the current battery pack is less than a set threshold or that the current battery pack is faulty, then determining the target battery pack and generating a switching instruction based on the information of the target battery pack.

[0089] The threshold value can be preset. In this embodiment, the threshold value can be set according to actual needs. For example, the threshold value in this embodiment can be 6% of the total battery pack volume.

[0090] In this embodiment, a target battery pack can be determined based on the remaining charge or operating status of the current battery pack in the test information. Then, a switching command is generated based on the information of the determined target battery pack, facilitating the switching of the current battery pack. Specifically, if the remaining charge of the current battery pack is less than a set threshold or the current battery pack is faulty, a target battery pack can be determined based on at least one backup battery pack, and a switching command is generated based on the information of the target battery pack. This configuration allows for unmanned, automated battery testing within a set timeframe in the laboratory, improving battery testing efficiency, reducing the impact of uncontrollable factors on test results during real-vehicle road testing, and better ensuring test consistency and the accuracy of test data.

[0091] In this embodiment, optionally, determining the target battery pack includes: obtaining the remaining power of the untested battery packs; and selecting the untested battery pack with the smallest remaining power as the target battery pack.

[0092] In this context, "untested battery packs" can be understood as battery packs that have not yet been tested, excluding the one currently being tested. In this embodiment, the remaining power of the untested battery packs can be obtained, and the battery pack with the lowest remaining power is selected as the target battery pack. For example, this embodiment can detect the status information of the battery packs in real time. If one untested battery pack has 100% remaining power and another has 80% remaining power, then the untested battery pack with 80% remaining power is selected as the target battery pack. This configuration allows for priority testing of battery packs with low remaining power, facilitating centralized charging by staff.

[0093] Furthermore, this embodiment can also classify charging methods according to conventional chargers and input the charging patterns of different methods (e.g., constant current, constant voltage, constant power, pulse, and three-stage methods) into the charging cabinet to test the charging adaptability of the fast-swap battery. This ensures that the vehicle can adapt to various local charging methods when operating on regular roads or in different regions, and tests the charging stability and adaptability of the fast-swap battery. This embodiment enables the battery to simulate various charging methods in the laboratory, record charging data in real time for calculation and synchronous analysis, and generate test results synchronously when the test ends.

[0094] In this embodiment, the vehicle controller can control multiple battery packs to continuously switch between each other at a certain output power or at a certain cycle. Combined with a high-low temperature chamber and a charging / discharging cabinet, it can simulate the frequent switching of battery packs in different seasons and operating conditions of autonomous vehicles to verify reliability. This ensures the coverage and sufficiency of battery testing, reduces dependence on environment, manpower, and facilities, and enables efficient simulation of the stability and reliability of this special electrical architecture of autonomous vehicle battery switching under various operating conditions in the laboratory. Furthermore, it supports the synchronous processing and analysis of all test data, displaying test results through a human-machine interface screen in the laboratory, reducing labor costs and ensuring the accuracy of test data analysis.

[0095] S250: Switch from the current battery pack to the target battery pack according to the switching command.

[0096] S260. Take the target battery pack as the new current battery pack and return to execute the operation of testing the current battery pack in the test scenario based on the received operating condition cycle instruction until the test end condition is met, and obtain test information of at least two battery packs.

[0097] The technical solution of this invention involves: acquiring a temperature range and / or humidity range; configuring a test scenario with set operating conditions based on the temperature and / or humidity range; testing the current battery pack in the test scenario based on received operating condition cycle instructions to obtain test information for the current battery pack; generating a switching instruction based on the test information; switching from the current battery pack to a target battery pack according to the switching instruction; using the target battery pack as the new current battery pack; and returning to execute the operation of testing the current battery pack in the test scenario based on received operating condition cycle instructions until the test termination condition is met, thereby obtaining test information for at least two battery packs. This technical solution can obtain test data under various operating conditions, compress the test cycle, and improve the accuracy of the test data.
