[0044] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0045] A method for starting a hybrid vehicle comprises: obtaining battery pack information of the hybrid vehicle; obtaining a mapping relationship between the battery pack of the hybrid vehicle and temperature from the battery pack information; judging the starting risk of the hybrid vehicle based on the mapping relationship and the current remaining power of the battery pack; if the hybrid vehicle has a starting risk, starting the engine of the hybrid vehicle and charging the battery pack after starting, so as to start the hybrid vehicle in a low temperature environment.

[0046] See also Figure 1 , Figure 1 A schematic diagram of a process flow of a hybrid vehicle starting method provided in an embodiment of the present application. The specific process flow of the hybrid vehicle starting method may be as follows:

[0047] 101. Obtain the battery pack information of the hybrid vehicle.

[0048] Battery pack information refers to the detailed status and parameters of the battery pack in a hybrid or electric vehicle. This information is crucial to the Battery Management System (BMS) because it helps the BMS monitor, control and optimize the performance and life of the battery.

[0049] Among them, the battery pack information usually includes: battery type, number of battery cells, voltage and current, state of charge, health status and temperature. The battery type refers to the type of battery used in the battery pack, such as lithium-ion battery, nickel-metal hydride battery, etc. The number of battery cells refers to the number of battery cells or battery modules contained in the battery pack. The state of charge refers to the percentage of the current remaining power of the battery pack and is one of the most important parameters in the battery management system. The health status reflects the aging degree and performance degradation of the battery.

[0050] 102. Obtain a mapping relationship between a battery pack and temperature of a hybrid vehicle from battery pack information.

[0051] In hybrid electric vehicles, the mapping relationship between the battery pack and temperature is crucial for the battery management system (BMS). The mapping relationship refers to the relationship between the state of charge (SOC) and temperature of the battery pack of the hybrid electric vehicle. This mapping relationship is preset by collecting data through experimental tests. For example, data can be collected through experimental tests, including charging and discharging tests on the battery pack under different temperature conditions, recording battery parameters such as voltage, current, temperature and SOC, and analyzing the collected data to determine the performance of the battery at different temperatures. Based on the experimental data, a mapping model is established that can describe the relationship between the SOC (State of Charge) and temperature of the battery pack (i.e., the mapping relationship). This model can be linear or nonlinear, depending on the characteristics of the data. Then, the accuracy of the mapping model is verified through additional tests. The verified mapping model is integrated into the BMS. In this way, the BMS can use this model to predict the SOC of the battery at a specific temperature, thereby better managing the battery charging and discharging process.

[0052] Optionally, in some embodiments of the present application, before the step of “obtaining a mapping relationship between a battery pack of a hybrid vehicle and temperature from the battery pack information”, the following may also be specifically included:

[0053] Obtain the short-term peak power of each cell in the battery pack at different temperatures;

[0054] According to the minimum starting power corresponding to the hybrid vehicle and the short-term peak power of each battery cell at different temperatures, a mapping relationship between the battery pack of the hybrid vehicle and the temperature is established;

[0055] The mapping relationship is stored in the battery pack information corresponding to the battery pack.

[0056] For example, specifically, through experimental testing, the short-term peak power data of the battery pack at different temperatures is collected. This usually involves charging and discharging the battery pack in a controlled environment and recording the peak power performance under different temperature conditions. According to the design requirements of the hybrid vehicle, the minimum starting power required for the engine to start is determined. Using the collected data, a mapping relationship is established between the short-term peak power of each cell in the battery pack at different temperatures and the minimum starting power of the hybrid vehicle to determine whether the battery pack can provide sufficient power to start the engine at different temperatures. The established mapping relationship is stored in the battery pack information to ensure that this information can be accessed before the hybrid vehicle is started.

[0057] 103. Based on the mapping relationship and the current remaining power of the battery pack, determine the starting risk of the hybrid vehicle.

[0058] For example, the BMS monitors the SOC and temperature of the battery pack in real time. For example, if the current SOC is 30% and the battery pack temperature is -5°C, the BMS then queries the corresponding short-term peak power in the mapping table based on the current SOC and temperature. As the query results show, under the conditions of 30% SOC and -5°C, the short-term peak power of the battery pack is 2.5kW. The BMS compares the queried short-term peak power with the minimum starting power required for the hybrid vehicle. For example, the minimum starting power requirement of the vehicle is 3kW; if the queried short-term peak power (2.5kW) is lower than the required minimum starting power (3kW), the BMS will assess that there is a starting risk, and then execute step 104.

[0059] Optionally, in some embodiments of the present application, the step of “determining the starting risk of the hybrid vehicle based on the mapping relationship and the current remaining power of the battery pack” may specifically include:

[0060] According to the mapping relationship, determine the starting temperature corresponding to the current remaining power of the battery pack;

[0061] The starting risk of the hybrid vehicle is determined based on the starting temperature and the actual temperature of the battery pack.

[0062] First, the BMS determines the starting temperature corresponding to the current remaining power of the battery pack based on the mapping relationship. At the same time, it obtains the current actual temperature of the battery from the battery pack information. Finally, the starting temperature and the current actual temperature of the battery pack can be compared to determine the starting risk of the hybrid vehicle.

[0063] Optionally, in some embodiments of the present application, the step of “determining the starting temperature corresponding to the current remaining power of the battery pack according to the mapping relationship” may specifically include:

[0064] After a preset time interval, obtaining the highest voltage and the lowest voltage of a single cell of the battery pack;

[0065] Based on the maximum voltage and the minimum voltage of the single cell, the starting temperature corresponding to the current remaining power of the battery pack is determined.

[0066] The lowest cell voltage refers to the voltage value of the battery cell with the lowest voltage among all the battery cells in the battery pack, and the highest cell voltage refers to the voltage value of the battery cell with the highest voltage among all the battery cells in the battery pack.

[0067] For example, specifically, the maximum cell voltage and the minimum cell voltage of the battery pack are obtained after a preset time interval. According to the maximum cell voltage and the minimum cell voltage, the voltage distribution of the battery pack in the current state. Then, using the voltage data (i.e., the maximum cell voltage and the minimum cell voltage), the current SOC of the battery pack is estimated through the voltage-SOC (State of Charge) mapping table. The voltage-SOC (State of Charge) mapping table is established based on battery characteristics and historical data, and is used to convert voltage into an estimated value of SOC. Finally, based on the queried SOC and the current temperature of the battery pack, determine whether the battery pack can provide sufficient power to start the engine.

[0068] Optionally, in some embodiments of the present application, the step of “determining the starting risk of the hybrid vehicle based on the starting temperature and the current actual temperature of the battery pack” may specifically include:

[0069] If the actual temperature of the battery pack is lower than the starting temperature, it is determined that the hybrid vehicle has a starting risk;

[0070] If the current actual temperature of the battery pack is higher than the starting temperature, it is determined that there is no starting risk for the hybrid vehicle.

[0071] For example, specifically, the lowest temperature at which the battery pack can provide sufficient starting power at the current SOC, that is, the starting temperature, is determined based on the current SOC (State of Charge) of the battery pack and the pre-established SOC-temperature-power mapping table. At the same time, the actual temperature of the battery pack in real time is obtained. If the actual temperature of the battery pack is lower than the starting temperature, this means that at the current SOC, the battery may not be able to provide enough power to start the engine, so there is a starting risk. If the actual temperature of the battery pack is higher than the starting temperature, this means that the battery should be able to provide enough power to start the engine at the current SOC, so there is no starting risk.

[0072] Optionally, in some embodiments of the present application, the step of “if the current actual temperature of the battery pack is higher than the starting temperature, determining that the hybrid vehicle does not have a starting risk” may specifically include:

[0073] Trigger to enter the dormant state;

[0074] After a preset time interval, the dormant state is released, and the process returns to the step of determining the starting risk of the hybrid vehicle based on the mapping relationship and the current remaining power of the battery pack.

[0075] For example, in the case where it is determined that there is no risk of starting, the sleep state is triggered to save energy. After a preset time interval, the BMS will terminate the sleep state, and then the detection involves checking the status of the vehicle, such as whether the driver's start signal or other wake-up signal is received. After the sleep state is terminated, the BMS will re-execute the step of determining the start risk of the hybrid vehicle based on the mapping relationship and the current remaining power of the battery pack.

[0076] 104. If there is a risk of starting the hybrid vehicle, start the engine of the hybrid vehicle and charge the battery pack after starting so as to start the hybrid vehicle in a low temperature environment.

[0077] For example, if there is a risk of starting a hybrid vehicle, the BMS will send a signal to the vehicle controller to request to start the engine, which can provide additional energy for the battery pack. The electricity generated by the engine is used to charge the battery pack through the charging system, increasing the battery's SOC and ensuring that the battery has enough energy to support the vehicle's start and operation.

[0078] Optionally, in some embodiments of the present application, the step of “if there is a risk of starting the hybrid vehicle, starting the engine of the hybrid vehicle, and charging the battery pack after starting, so as to start the hybrid vehicle in a low temperature environment” may specifically include:

[0079] If there is a risk of starting the hybrid vehicle, a charging request is sent to a controller of the hybrid vehicle, so that the controller starts the engine of the hybrid vehicle after receiving the charging request, and charges the battery pack after starting;

[0080] When the battery pack is charged to a preset state, a power-off request is sent to the controller to start the hybrid vehicle in a low-temperature environment.

[0081] If it is determined that there is a risk of starting, a charging request will be sent to the controller of the hybrid vehicle. After receiving the charging request, the controller of the hybrid vehicle will start the engine. After the engine is started, it will drive the generator to generate electricity to charge the battery pack. The generated electricity is used to charge the battery pack through the charging system to increase the battery's SOC and ensure that the battery has enough energy to support the starting and operation of the vehicle. During the charging process, the status of the battery pack continues to be monitored, including voltage, current, temperature, etc., to ensure that the charging process is safe and efficient. When the SOC or voltage of the battery pack reaches the preset starting level, a power-off request is sent to the controller to indicate that the battery pack has been charged to the preset state and the vehicle is ready to be started.

[0082] The embodiment of the present application provides a method for starting a hybrid vehicle. After obtaining the battery pack information of the hybrid vehicle, the mapping relationship between the battery pack of the hybrid vehicle and the temperature is obtained from the battery pack information. Then, based on the mapping relationship and the current remaining power of the battery pack, the starting risk of the hybrid vehicle is judged. If the hybrid vehicle has a starting risk, the engine of the hybrid vehicle is started, and the battery pack is charged after starting, so as to start the hybrid vehicle in a low temperature environment. The starting scheme of the hybrid vehicle provided by the present application, at low temperatures, based on the mapping relationship between the battery pack of the hybrid vehicle and the temperature and the current remaining power of the battery pack, the starting risk of the hybrid vehicle is judged. If the hybrid vehicle has a starting risk, the engine of the hybrid vehicle is started, and the battery pack is charged after starting, thereby increasing the available capacity of the battery and reducing the risk that the engine of the hybrid vehicle cannot be started at low temperatures.

[0087] When there is a risk of starting the hybrid vehicle, the power control unit 203 controls the engine 201 to start so as to charge the battery pack 202 .

[0088] The embodiment of the present application provides a hybrid vehicle starting system, in which the power control unit 203 transmits information with the battery management system built into the battery pack 202 through a message, and the battery management system built into the battery pack 202 can judge the starting risk of the hybrid vehicle based on the mapping relationship between the battery pack of the hybrid vehicle and the temperature and the current remaining power of the battery pack 202. When the hybrid vehicle has a starting risk, the power control unit 203 controls the engine 201 to start to charge the battery pack 202. The hybrid vehicle starting scheme provided by the present application judges the starting risk of the hybrid vehicle based on the mapping relationship between the battery pack of the hybrid vehicle and the temperature and the current remaining power of the battery pack at low temperatures. If the hybrid vehicle has a starting risk, the engine of the hybrid vehicle is started, and the battery pack is charged after starting, thereby increasing the available capacity of the battery and reducing the risk that the engine of the hybrid vehicle cannot be started at low temperatures.
