[0032] like Figure 1 As shown, the method includes steps S110 to S160.

[0033] S110, the battery pack temperature measurement system and the cabin temperature measurement system respectively monitor the temperature of the battery pack and the cabin in the intelligent control system in real time to obtain the battery pack temperature and the cabin temperature.

[0034] In this embodiment, during the operation of the new energy vehicle, the battery pack and the cabin are respectively provided with independent battery pack temperature measurement systems and cabin temperature measurement systems; wherein, the battery pack temperature measurement system and the cabin temperature measurement system both include temperature sensors; the battery pack temperature measurement system obtains the battery pack temperature by monitoring the battery pack; the cabin temperature measurement system obtains the cabin temperature by monitoring the temperature in the cabin, and then uses the battery pack temperature and the cabin temperature to facilitate subsequent calculation of excess heat of the battery pack and excess heat of the cabin.

[0035] In one embodiment, after obtaining the battery pack temperature and the cabin temperature, the method further includes:

[0036] If the controller determines that the battery pack temperature monitored by the battery pack temperature measurement system is less than the first preset temperature threshold, the controller controls the battery pack to enter a dormant state; and / or

[0037] If the controller determines that the cabin temperature monitored by the cabin temperature measurement system is less than the second preset temperature threshold, the controller controls the cabin to enter a dormant state.

[0038] In this embodiment, in order to reduce the power consumption of the battery pack and the cabin, after obtaining the battery pack temperature and the cabin temperature, the battery pack temperature measurement system determines whether the battery pack temperature is greater than a first preset temperature threshold, and at the same time, the cabin temperature measurement system determines whether the cabin temperature is greater than a second preset temperature threshold. If the controller determines that the battery pack temperature monitored by the battery pack temperature measurement system is less than the first preset temperature threshold, the battery pack is controlled to enter a dormant state; and / or if the controller determines that the cabin temperature monitored by the cabin temperature measurement system is less than the second preset temperature threshold, the cabin is controlled to enter a dormant state, thereby effectively protecting the battery and the cabin by controlling the entry into the dormant mode to prevent damage due to excessive use, thereby extending the service life of the battery and the cabin.

[0039] S120. If the controller determines that the battery pack temperature monitored by the battery pack temperature measurement system is greater than a first preset temperature threshold and / or the cabin temperature monitored by the cabin temperature measurement system is greater than a second preset temperature threshold, it generates a first control signal and / or a second control signal, and sends the first control signal to the battery pack heat exchange device and / or sends the second control signal to the cabin heat exchange device.

[0040] In this embodiment, the ideal operating temperature of the battery pack in the new energy vehicle is generally within 35°C, and the cabin is usually maintained at 20-25°C to meet the passenger comfort requirements. Therefore, after the battery pack temperature measurement system and the cabin temperature measurement system respectively monitor the battery pack temperature and the cabin temperature, the battery pack temperature measurement system determines whether the battery pack temperature is greater than a first preset temperature threshold, and at the same time, the cabin temperature measurement system determines whether the cabin temperature is greater than a second preset temperature threshold; wherein, the first preset temperature threshold is preferably 35°C in this embodiment; if the controller determines that the battery pack temperature monitored by the battery pack temperature measurement system is greater than When the cabin temperature is greater than the second preset temperature threshold at the first preset temperature threshold and / or the cabin temperature monitored by the cabin temperature measurement system, a first control signal and / or a second control signal is generated, and the first control signal is sent to the battery pack heat exchange device and / or the second control signal is sent to the cabin heat exchange device, so that the battery pack heat exchange device can subsequently convert the excess heat of the battery pack temperature greater than the first preset temperature threshold into energy according to the first control signal, and / or the cabin heat exchange device can convert the excess heat of the cabin greater than the second preset temperature threshold into energy according to the second control signal.

[0041] S130. When the battery pack heat exchange device receives the first control signal, it converts the first heat to be converted of the battery pack based on a first conversion strategy corresponding to the first control signal and stores it in the energy storage battery.

[0042] In this embodiment, in order to achieve energy conversion, the battery pack heat exchange device starts working when receiving the first control signal, and converts the first heat to be converted of the battery pack based on the first conversion strategy corresponding to the first control signal and stores it in the energy storage battery, wherein the first heat to be converted is the excess heat corresponding to the battery pack temperature exceeding the first preset temperature threshold; therefore, this embodiment, while achieving energy conversion, stores the electric energy after the energy conversion of the first heat to be converted into the energy storage battery, so that the electric energy stored in the energy storage battery can be used later according to actual needs.

[0043] In one embodiment, the first conversion strategy corresponding to the first control signal is used to convert the first heat to be converted of the battery pack and store it in the energy storage battery, including:

[0044] The battery pack heat exchange device obtains the battery pack temperature, the first preset temperature threshold, the mass of the battery pack and the specific heat capacity of the battery cells in the battery pack;

[0045] The battery pack heat exchange device determines the first heat to be converted based on the battery pack temperature, the first preset temperature threshold, the mass of the battery pack and the specific heat capacity of the battery cells in the battery pack;

[0046] The battery pack heat exchange device converts the first heat to be converted into first target electric energy, and stores the first target electric energy in the energy storage battery.

[0047] In this embodiment, in order to calculate the first target electric energy, the battery pack heat exchange device obtains the battery pack temperature, the first preset temperature threshold, the mass of the battery pack and the specific heat capacity of the battery cells in the battery pack based on the first conversion strategy corresponding to the first control signal, and calculates the battery pack temperature, the first preset temperature threshold, the mass of the battery pack and the specific heat capacity of the battery cells in the battery pack through the following formula to obtain the first heat to be converted of the battery pack; wherein the formula is Q1=c1m1△T1, Q1 represents the first heat to be converted, c1 represents the specific heat capacity of the battery cell, m1 represents the mass of the battery pack, and △T1 represents the temperature difference between the battery pack temperature and the first preset temperature threshold. In addition, after determining the first heat to be converted, the battery pack heat exchange device converts the first heat to be converted into the first target electric energy and charges it into the energy storage battery for storage.

[0048] In one embodiment, after the first conversion strategy corresponding to the first control signal is used to convert the first heat to be converted of the battery pack and stores it in the energy storage battery, the method further includes:

[0049] The controller obtains a pre-stored historical first target electric energy set and a historical first heat set to be converted corresponding to the battery pack; wherein each historical first target electric energy in the historical first target electric energy set corresponds to each historical first heat set to be converted;

[0050] The controller performs a division operation on each historical first target electric energy and the corresponding historical first heat to be converted to obtain each first conversion rate;

[0051] The controller performs a mean operation on each first conversion rate to obtain a first target conversion rate.

[0052] In this embodiment, in order to measure the conversion efficiency and abnormal aging state of the battery pack heat exchange device, the controller in this embodiment obtains the pre-stored historical first target electric energy set and the historical first heat set to be converted corresponding to the battery pack; wherein each first target electric energy in the historical first target electric energy set corresponds to each first heat to be converted in the historical first heat set to be converted; and each first target electric energy and the first heat to be converted corresponding to each first target electric energy are divided to obtain each first conversion rate; and each first conversion rate is averaged to obtain the first target conversion rate. In addition, after obtaining the first target conversion rate, it specifically includes: the controller obtains the current first target electric energy and the current first heat to be converted; the first target electric energy is divided by the first heat to be converted to obtain the second conversion rate; and the controller judges the size of the second conversion rate and the first target conversion rate. If it is determined that the second conversion rate is less than the first target conversion rate, it means that the conversion efficiency of the battery pack heat exchange device is low and it is in an abnormal aging state, and generates a first abnormal prompt information to prompt the user to take measures such as timely replacement.

[0053] S140. When the cabin heat exchange device receives the second control signal, the cabin heat exchange device performs energy conversion on the second heat to be converted in the cabin based on a second conversion strategy corresponding to the second control signal and stores the energy in the energy storage battery.

[0054] In this embodiment, in order to realize the energy conversion of the cabin heat exchange device, the cabin heat exchange device starts to work when receiving the second control signal, and converts the second heat to be converted in the cabin based on the second conversion strategy corresponding to the second control signal and stores it in the energy storage battery, wherein the second heat to be converted is the excess heat corresponding to the cabin temperature exceeding the second preset temperature threshold; therefore, this embodiment stores the electric energy after the energy conversion of the second heat to be converted in the energy storage battery while realizing energy conversion, so that the electric energy stored in the energy storage battery can be used later according to actual needs.

[0055] In a further embodiment, the converting the second heat to be converted of the cabin into energy based on the second conversion strategy corresponding to the second control signal and storing it in the energy storage battery includes:

[0056] The cabin heat exchange device acquires the cabin temperature, the second preset temperature threshold, the mass of the air in the cabin, and the specific heat capacity of the air in the cabin;

[0057] The cabin heat exchange device determines a second amount of heat to be converted in the cabin based on the cabin temperature, the second preset temperature threshold, the mass of the air in the cabin, and the specific heat capacity of the air in the cabin;

[0058] The cabin heat exchange device converts the second to-be-converted heat of the cabin into second target electric energy, and stores the second target electric energy in the energy storage battery.

[0059] In this embodiment, in order to calculate the second target electric energy, the cabin heat exchange device obtains the cabin temperature, the second preset temperature threshold, the mass of the air in the cabin and the specific heat capacity of the air in the cabin based on the second conversion strategy corresponding to the second control signal, and calculates the cabin temperature, the second preset temperature threshold, the mass of the air in the cabin and the specific heat capacity of the air in the cabin by the following formula to obtain the second heat to be converted in the cabin; wherein the formula is Q2=c2m2△T2, Q2 represents the second heat to be converted, c2 represents the specific heat capacity of the air in the cabin, m2 represents the mass of the air in the cabin, and △T2 represents the temperature difference between the cabin temperature and the second preset temperature threshold. In addition, after determining the second heat to be converted, the cabin heat exchange device converts the second heat to be converted in the cabin into the second target electric energy, and charges it to the energy storage battery for storage.

[0060] In another embodiment, after the second conversion strategy corresponding to the second control signal is used to convert the second heat to be converted in the passenger cabin and stores it in the energy storage battery, the method includes:

[0061] The controller acquires a pre-stored historical second target electric energy set and a historical second heat set to be converted corresponding to the cabin; wherein each historical second target electric energy in the historical second target electric energy set corresponds one-to-one to each historical second heat set to be converted;

[0062] The controller performs a division operation on each historical second target electric energy and the corresponding historical second heat to be converted to obtain each third conversion rate;

[0063] The controller performs a mean operation on each third conversion rate to obtain a second target conversion rate.

[0064] In this embodiment, in order to measure the conversion efficiency and abnormal aging state of the cabin heat exchange device, the controller in this embodiment first obtains the pre-stored historical second target electric energy and the historical second heat to be converted corresponding to the cabin; wherein each historical second target electric energy in the historical second target electric energy set corresponds to each historical second heat to be converted in the historical second heat to be converted set; and divides each second target electric energy and the corresponding second heat to be converted to obtain each third conversion rate; and averages each third conversion rate to obtain the second target conversion rate. In addition, after obtaining the second target conversion rate, it specifically includes: the controller obtains the second target electric energy and the second heat to be converted; and divides the second target electric energy and the second heat to be converted to obtain the fourth conversion rate; and then the controller judges the size of the fourth conversion rate and the second target conversion rate. If it is determined that the fourth conversion rate is less than the second target conversion rate, it means that the cabin heat exchange device has a low conversion efficiency and is in an abnormal aging state, and generates a third abnormal prompt information to prompt the user to take measures such as timely replacement.

[0065] S150: When it is determined that the energy storage battery is in a fully charged state, the total power of the battery pack is detected to obtain a detection result.

[0066] In this embodiment, since the energy storage battery itself has logical judgment capability, after the energy storage battery stores the first target electric energy corresponding to the first heat to be converted and the second target electric energy corresponding to the first heat to be converted, the energy storage battery judges the electric energy stored in itself. When it is determined that it is in a fully charged state, the energy storage battery further detects the total power of the battery pack to obtain a detection result including the power status of the battery pack; and when it is determined that the energy storage battery is in a state to be fully charged, the charging operation continues until the energy storage battery is fully charged.

[0067] In one embodiment, after obtaining the detection result, the method further includes:

[0068] If the energy storage battery determines that the detection result is that the total power is less than the preset power threshold, there is no need to charge the battery pack.

[0069] In this embodiment, after obtaining the detection result, if the energy storage battery determines that the detection result is that the total power of the battery pack is less than the first preset power value, there is no need to charge the battery pack, and the first target electrical energy after the first heat energy to be converted of the battery pack and the second target electrical energy after the second heat energy to be converted of the cabin continue to be stored in the energy storage battery for emergency standby in emergency situations.

[0070] S160: If the energy storage battery determines that the detection result is that the total power is greater than the first preset power value, the battery pack is charged until the total power meets the second preset power value.

[0071] In this embodiment, after obtaining the detection result, if the energy storage battery determines that the detection result is that the total power of the battery pack is greater than the first preset power value, the electric energy of the energy storage battery is transferred to the battery pack to charge the battery pack until the total power of the battery pack meets the second preset power value, thereby increasing the total cruising range of the vehicle; wherein the first preset power value is the total power of the battery pack multiplied by a preset power ratio; the preset power ratio is preferably 5% in this embodiment; for example: if the total power of the battery pack is 50mA·h, then the first preset power value is 2.5mA·h.

[0072] In one embodiment, the intelligent control system further includes a monitoring module, the monitoring module is connected to the energy storage battery, and the method further includes:

[0073] The monitoring module collects the temperature of the energy storage battery in real time, obtains the temperature of the energy storage battery, and sends the temperature of the energy storage battery to the controller;

[0074] If the controller determines that the temperature of the energy storage battery is greater than a preset safety threshold, it generates second abnormal prompt information; wherein the second abnormal prompt information is used to prompt that the energy storage battery is in an overheated state.

[0075] In this embodiment, in order to effectively manage the temperature of the energy storage battery to ensure that the energy storage battery works normally within an appropriate temperature range, the intelligent control system also includes a monitoring module, which is connected to the energy storage battery; wherein, during the charging and discharging process of the energy storage battery, the monitoring module collects the operating temperature of the energy storage battery in real time to obtain the energy storage battery temperature, and sends the energy storage battery temperature to the controller; after receiving the energy storage battery temperature, if the controller determines that the energy storage battery temperature is greater than a preset safety threshold, it indicates that the current energy storage battery temperature has risen abnormally, and a second abnormal prompt information is generated at this time, so that relevant staff can take corresponding heat dissipation or cooling measures in time to avoid safety risks caused by overheating of the energy storage battery. ‌

[0076] It can be seen from the above technical solutions that the present invention converts the excess heat generated by the battery pack and the passenger compartment into electrical energy and charges the battery pack to increase the vehicle's endurance, and reduces the heat generated by the battery pack and the passenger compartment.

In addition, after determining the second heat to be converted, the cabin heat exchange device converts the second heat to be converted in the cabin into the second target electric energy, and charges it to the energy storage battery for storage.

[0105] In another embodiment, after the second conversion strategy corresponding to the second control signal is used to convert the second heat to be converted in the cabin 130 and stores it in the energy storage battery 180, the method includes:

[0106] The controller 100 is used to obtain a pre-stored historical second target electric energy set and a historical second heat set to be converted corresponding to the cabin 130; wherein each historical second target electric energy in the historical second target electric energy set corresponds to each historical second heat set to be converted;

[0110] The energy storage battery 180 is used to detect the total power of the battery pack 120 to obtain a detection result when it is determined that the energy storage battery 180 is in a fully charged state.

[0111] In this embodiment, since the energy storage battery itself has logical judgment capability, after the energy storage battery stores the first target electric energy corresponding to the first heat to be converted and the second target electric energy corresponding to the first heat to be converted, the energy storage battery judges the electric energy stored in itself. When it is determined that it is in a fully charged state, the energy storage battery further detects the total power of the battery pack to obtain a detection result including the power status of the battery pack; and when it is determined that the energy storage battery is in a state to be fully charged, the charging operation continues until the energy storage battery is fully charged.

[0120] In this embodiment, in order to effectively manage the temperature of the energy storage battery to ensure that the energy storage battery works normally within an appropriate temperature range, the intelligent control system also includes a monitoring module, which is connected to the energy storage battery; wherein, during the charging and discharging process of the energy storage battery, the monitoring module collects the working temperature of the energy storage battery in real time to obtain the temperature of the energy storage battery, and sends the temperature of the energy storage battery to the controller; after receiving the temperature of the energy storage battery, if the controller determines that the temperature of the energy storage battery is greater than a preset safety threshold, it indicates that the current temperature of the energy storage battery is abnormally increased, and at this time, a second abnormal prompt information is generated, so that relevant staff can take corresponding heat dissipation or cooling measures in time to avoid safety risks caused by overheating of the energy storage battery.
