All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, more and more new energy automobiles begin to enter the lives of people. The pure electric vehicle is powered by the battery, does not generate waste gas, and is more environment-friendly compared with the vehicle using the traditional fuel. However, there are some disadvantages in battery power supply, the charging speed of the battery is greatly influenced by the ambient temperature, and the charging speed of the battery is slower under the condition of lower ambient temperature.
In the related art, the battery heating function is started during the parking charging to increase the battery temperature and accelerate the charging speed, but the battery heating process also takes time, and overall, the charging takes longer time.
Based on this, the application provides a method for preheating for battery, preheats the battery before the vehicle arrives and fills electric pile, reduces the latency in the charging process, reduces to charge consuming time when improving charging speed, further improves charge efficiency.
Fig. 1 is a schematic diagram of an application scenario provided by the present application, where a vehicle 101 currently located at a is ready to go to a charging station B where a charging pile 102 is located for charging, and during a driving process, the battery is heated, and after the vehicle reaches the charging station B, the vehicle is directly charged, and after the charging is completed, the vehicle leaves. In the whole process, the time for heating the battery and the driving time are the same time, the time is not additionally occupied, but the battery temperature is improved due to the fact that the battery is heated, the charging speed of the charging pile 102 is increased, the charging time is correspondingly reduced, and the whole charging efficiency is improved.
Example one
Fig. 2 is a flowchart of a method for heating a battery of a vehicle according to an embodiment of the present disclosure, and as shown in fig. 2, the method of the present embodiment may include:
s201, a charging instruction is obtained, and the charging instruction comprises position information of a charging pile.
The obtained charging instruction contains the position information of the charging pile, and can indicate the position of the charging pile to be visited.
In some specific implementation manners, a charging instruction sent by the intelligent terminal may be obtained, for example, the user sends the charging instruction through terminal equipment such as a smart phone after starting a vehicle; in other specific implementation manners, the charging instruction sent by the vehicle-mounted computer may be obtained, for example, the charging instruction is sent by the vehicle-mounted computer after the user finds that the remaining battery capacity is low in the driving process, or the charging instruction is automatically sent by the vehicle-mounted computer after the vehicle-mounted computer receives the prompt that the remaining battery capacity of the battery management system is low.
S202, acquiring the current temperature of the battery.
And S203, if the current temperature is lower than the preset temperature, heating the battery on the way of the vehicle running from the current position to the position of the charging pile.
Only when the current temperature of the battery is lower than the preset temperature, the battery needs to be heated, so that the current temperature is acquired and compared with the preset temperature. The preset temperature is a set value, and the value of the preset temperature can be selected to be within the optimal charging temperature range of the battery. The optimum charging temperature of the battery, here means that the charging rate of the battery is the highest at this temperature. The determination mode of the optimal charging temperature can be obtained by directly consulting relevant data or performing relevant experiments. The heating process may heat the battery at some fixed rate.
According to the method provided by the embodiment, when the charging instruction is obtained and the current temperature of the battery is detected to be lower than the preset temperature, the battery is heated on the way when the vehicle drives to the charging pile, so that the temperature of the battery is increased when the vehicle reaches the charging pile, and the battery is not required to be heated by spending too much time when the vehicle reaches the charging pile, so that the charging rate is increased, the charging time is reduced, and the charging efficiency is improved.
Before the battery is heated, the current remaining capacity of the battery can be acquired. Accordingly, one possible implementation manner of the above S203 may be: when the current temperature is lower than the preset temperature and the current residual capacity is larger than or equal to the preset capacity, the battery is heated on the way that the vehicle runs from the current position to the position of the charging pile.
The premise of heating the battery is to ensure that the vehicle can normally run to the charging pile. The preset electric quantity can be a fixed value, the current residual electric quantity of the vehicle is larger than the preset electric quantity, the battery can provide energy for the heating process, and the battery is heated at the moment.
Example two
Fig. 3 is a flowchart of a method for heating a battery of a vehicle according to a second embodiment of the present disclosure, and as shown in fig. 3, the method of the present embodiment may include:
s301, a charging instruction is obtained, and the charging instruction comprises position information of the charging pile.
And S302, acquiring the current temperature of the battery.
In this embodiment, the specific implementation process of steps S301 to S302 may refer to the related description of the embodiment shown in fig. 2, and is not described herein again.
And S303, if the current temperature is lower than the preset temperature, acquiring the current running speed and the position information of the current position of the vehicle.
S304, obtaining the heating rate of the battery according to the position information of the charging pile, the position information of the current position, the current temperature, the preset temperature and the current running speed.
S305, heating the battery according to the heating rate on the way of the vehicle from the current position to the position of the charging pile.
The heating rate can be obtained by the temperature and the heating time that need to heat, and the temperature that needs to heat can be obtained by current temperature and preset temperature, and the heating time can be decided by the travel time and obtains, like this, acquires the positional information of current speed and current position, and the positional information, the current temperature of combining again and filling electric pile, preset temperature can obtain the heating rate, heats the battery according to this heating rate again.
According to the method provided by the embodiment, the current driving speed and the current position information are obtained, the position information of the charging pile is combined, the current temperature and the preset temperature are obtained, the heating rate is obtained, then the battery is heated according to the obtained heating rate, so that when a vehicle arrives at the charging pile, the temperature of the battery can reach or approach the optimal charging temperature, the heating time of the battery when the vehicle arrives at the charging pile is reduced, even the battery can be directly charged without reheating, the charging time is reduced while the charging speed is increased, and the charging efficiency is further improved.
One possible implementation manner of the above S304 may be: determining the driving distance of the vehicle according to the position information of the charging pile and the position information of the current position; determining the running time of the vehicle according to the running distance and the current running speed; determining the temperature to be heated according to the temperature difference between the current temperature and the preset temperature; and determining the heating rate according to the temperature difference and the running time.
For example, fig. 4 is a schematic view of another application scenario provided in the present application. The vehicle 101 is currently located at the position C, runs to the position D where the charging pile 102 is located at the speed V of 40km/h, and after receiving a charging instruction, detects that the current battery temperature is 8 ℃ and the preset temperature is 26 ℃ to prepare for starting to heat the battery. And determining that the running distance L from the C to the D is 10km through navigation data, determining that the running time is 15 minutes by dividing the running distance by the running speed V, determining that the temperature difference is 18 ℃ by subtracting the current temperature from the preset temperature, and obtaining a value of 1.2 ℃/min by dividing the temperature difference by the running time.
In an actual driving environment, the current driving speed may not be maintained all the time under the influence of road conditions, so that the obtained driving time is an estimated value, and the heating rate calculated based on the driving time is also an estimated value, so that a value 1.2 ℃/min obtained by dividing the temperature difference by the driving time is directly used as the heating rate, the battery is heated according to the heating rate of 1.2 ℃/min, or the heating rate can be determined according to a value 1.2 ℃/min obtained by dividing the temperature difference by the driving time and a preset value, wherein the heating rate can be the sum or the product of the 1.2 ℃/min and the preset value, and then the battery is heated according to the heating rate, so as to ensure that the battery is heated to be more than or equal to the preset temperature within the driving time as much as possible.
And when the current temperature of the battery is greater than or equal to the preset temperature and/or the current residual electric quantity of the battery is less than the preset electric quantity, stopping heating the battery.
For example, after heating is started, the current temperature value of the battery may be obtained in real time and compared with the preset temperature, and if the current temperature of the battery is greater than or equal to the preset temperature, which indicates that the battery heating is completed, the battery heating is stopped, so as to save energy. The current residual capacity of the battery can be acquired in real time after the heating is started, the current residual capacity of the battery is compared with the preset capacity, the battery is stopped being heated when the current residual capacity of the battery is smaller than the preset capacity which indicates that the battery does not have redundant energy for heating, and the vehicle can normally reach the charging pile. And after heating is started, the current temperature value and the current residual capacity of the battery are simultaneously acquired, and when either one of the current temperature value and the current residual capacity of the battery meets the conditions, the battery is stopped being heated.
The preset electric quantity can be larger than the electric quantity required to be consumed from the current position to the position of the charging pile, and can also be larger than or equal to the sum of the electric quantity required to be consumed from the current position to the position of the charging pile and the electric quantity required to be consumed for increasing the current temperature to the preset temperature.
