And 103, controlling the electric scooter to charge or discharge the battery according to the control instruction.
The control instruction in this embodiment is used to control the electric scooter to charge or discharge the battery, where the control instruction includes control parameters of battery charging, such as charging current, discharging current, charging upper limit, charging time, starting charging and stopping charging, and the like, so that dynamic management of battery charging and discharging is performed by adjusting the control instruction based on the acquired data, thereby improving safety protection of battery charging and discharging, and increasing service life and service cycle of the battery.
In the control method for charging and discharging the battery, under the condition that the electric quantity of the electric scooter is monitored to be lower than a threshold value and/or a charging and discharging instruction is received, state information of the battery of the electric scooter is acquired, the control instruction is determined according to the state information and/or the historical use record of the battery, the electric scooter is controlled to charge or discharge the battery according to the control instruction, and dynamic management is carried out on charging and discharging of the battery by acquiring battery state data and dynamically matching charging behaviors and habits of a user in the application so as to improve charging and discharging safety protection of the battery and increase service life and service cycle of the battery.
Based on the previous embodiment, this embodiment provides another method for controlling charging and discharging of a battery, and fig. 2 is a schematic flow diagram of another method for controlling charging and discharging of a battery according to the embodiment of the present application.
As shown in fig. 2, the method may include the steps of:
Specifically, reference may be made to the related description in the previous embodiment, and the principle is the same, which is not described again in this embodiment.
In this embodiment, a server is taken as an example for explanation. As shown in fig. 3, the cloud server obtains the state information of the battery of the electric scooter, and the state information is used for representing one or more combinations of the remaining capacity, the driving range, the battery temperature, the ambient temperature and the geographical location of the battery of the electric scooter.
In step 202, a control command is determined according to the state information and/or the historical usage record of the battery.
In this embodiment, according to different scenarios, based on the acquired data, a corresponding control instruction may be generated, where the control instruction includes a corresponding control parameter, which is described in detail below.
In an implementation manner of this embodiment, the cloud server obtains a historical usage record of the battery of the electric scooter, and determines the control instruction according to the historical usage record, which is described below with respect to different scenarios.
In a scenario of this embodiment, according to the historical usage record, if it is determined that the charging number of the battery is the first charging, it is determined that the charging mode in the control parameter of the control instruction is the constant current.
In another scenario of this embodiment, if it is determined that the number of times of charging the battery is greater than the threshold number of times or the total driving range is greater than the threshold range, the charging upper limit capacity in the control parameter of the control command is determined to be a set proportion of the rated capacity of the battery, and/or the discharging current in the control parameter of the control command is determined to be a first set proportion of the rated current according to the historical usage record.
For example, the service life of the battery may be longer, for example, 5 years or 10 years, wherein each charging of the battery is recorded, and the service life may be determined according to the record of the charging times or according to the driving mileage. Since the charging and discharging of the battery have an upper usage limit, the number of charging and discharging of the battery is usually 800-1000, and when the charging and discharging cycle limit is reached, overcharge is performed, which is likely to cause a safety accident, therefore, when it is determined that the number of charging of the battery is greater than the threshold number, or the total driving range is greater than the threshold range, the upper charging limit electric quantity in the control parameter of the control instruction is determined to be a set proportion of the rated electric quantity of the battery, for example, set to be 25% of the rated electric quantity of the battery, for example, the rated electric quantity is 20Ah, and set to be 5 Ah. Alternatively, the discharge current may be set to a first set proportion of the rated current, for example, 50%, to achieve discharge without a large current, improving the usage rate.
In another scenario of this embodiment, the remaining capacity before charging and the remaining capacity after charging in each usage record are queried according to the historical usage records, and if the remaining capacity before charging is greater than the first threshold and the number of usage records whose remaining capacity after charging is greater than the second threshold is greater than the number threshold, the upper limit charging capacity in the control parameter of the control instruction is determined to be the second set proportion of the rated capacity.
For example, the user is usually accustomed to use at a low usage rate, and the user usually starts charging when the remaining battery capacity is 80%, and stops charging when the remaining battery capacity increases to 95% after charging. The charging habit enables the battery to be fully charged, but the discharging amount is small when the battery is used, and then the battery is continuously charged. Therefore, when the number of times of occurrence of the charging condition in each usage record is queried to be an excess threshold number of times, for example, 20 times, according to the obtained historical usage record, the upper charging limit electric quantity in the control parameter of the control instruction is determined to be 85% of the rated electric quantity, so that safety protection of battery charging is realized through dynamic adjustment, and the service life of the battery is prolonged.
As another implementation manner, the cloud server may further determine a control instruction according to the acquired state information of the current battery, and the following description is provided for different scenarios.
In one scenario, the state information includes an ambient temperature, and the cloud server determines, according to the ambient temperature in the acquired state information, that the ambient temperature is less than a lower temperature limit, or greater than an upper temperature limit, that is, the ambient temperature is lower or higher, and the ambient temperature is relatively severe, and then determines that the initial discharge current in the control parameter of the control instruction is a third set proportion of the rated current, for example, 50%.
In the use process of the battery, for example, when the battery starts to discharge, if the external environment temperature is low or high, in this embodiment, the environment temperature is low, and if the environment temperature is lower than-10 degrees or 20 degrees, at a low temperature, if the initial discharge current is large, the battery is easily damaged by high-power discharge, so that the initial discharge current needs to be limited to reduce the loss of the battery, the limitation of the discharge current by determining the environment temperature is realized, the safety protection of the battery discharge is realized, and the service life and the service cycle of the battery are increased.
In one implementation of the present application, at the initial stage of the battery starting to discharge, the external temperature is low, the initial discharge current needs to be reduced, and as the battery temperature gradually increases along with the discharge, the discharge current may be gradually increased, specifically, in the case that the battery temperature is adjusted to be within the set temperature interval, the discharge current in the control parameter of the control command is adjusted, so that the discharge current gradually increases until the rated current is reached, so as to improve the discharge efficiency.
As another implementation manner, the cloud server determines the control instruction according to the acquired current state information of the battery and the historical usage record of the battery.
For example, in one scenario, according to the acquired state information of the battery, it is determined that the current ambient temperature is less than the lower temperature limit, and meanwhile, the acquired historical usage record of the battery indicates that the number of times of charging the battery is greater than the threshold number of times, then it is determined that the upper charging limit electric quantity in the control parameters of the control instruction is a set proportion of the rated electric quantity of the battery, and the discharging electric quantity is controlled to be a fourth set proportion of the rated current, where the fourth set proportion is less than the first set proportion and less than the third set proportion.
It should be understood that, in this scenario, the battery life cycle is about to end while in a low-temperature environment, and therefore, the set upper charging limit capacity may be smaller than the set ratio.
It should be noted that, for other scenes according to the state information and the historical usage record of the battery, description is not repeated in this embodiment, and in various scenes, charging and discharging of the battery are protected by dynamic adjustment based on the acquired data, so as to increase the service life.
And step 203, controlling the electric scooter to charge or discharge the battery according to the control instruction.
And then, controlling the electric scooter to charge or discharge the battery according to the control instruction determined by the data acquired by the cloud server, so as to dynamically adjust the charging or discharging parameters through the acquired data, so as to perform safety protection on the charging and discharging of the battery, and improve the service life of the battery.
And step 204, inquiring weather and building information according to the geographic position in the state information. And step 205, controlling the electric scooter to stop executing the control command when the weather meets the set weather condition and the building information indicates the weather, or controlling the electric scooter to stop executing the control command after delaying the set time length, and/or controlling the electric scooter to stop executing the control command in response to the remote control operation of the user, or controlling the electric scooter to stop executing the control command after delaying the set time length.
In this embodiment, the positioning device is arranged on the electric scooter, the geographical position of the electric scooter can be determined according to the positioning device, whether the electric scooter is in an open air environment or not and a corresponding weather condition are inquired and determined according to the geographical position of the electric scooter, and if the weather is rainy weather and the building indication is in the open air condition, the electric scooter is automatically controlled to stop executing the control command, or the electric scooter is controlled to stop executing the control command after a set time length is delayed; and/or, in response to the remote control operation of a user, controlling the electric scooter to stop executing the control command, or delaying the set time length and then controlling the electric scooter to stop executing the control command, so that the damage of a charging circuit caused by charging in rainy days is prevented, and the service life of the battery is prolonged.
It should be noted that, by delaying the set time period and controlling the electric scooter to stop executing the control command, the arc discharge effect caused by sudden stop of charging of the electric scooter during heavy current charging can be avoided, the damage to the rechargeable battery can be avoided, and the safety of battery charging can be improved.
And step 206, generating a use record of the current charging or discharging according to one or more combinations of the state information of the battery before the current charging, the state information after the charging, the state information before the discharging and the state information after the discharging and the control parameters carried in the control command adopted by the current charging or discharging.
In this embodiment, a usage record of the current charging or discharging may be generated according to one or more combinations of the state information of the battery before the current charging, the state information after the charging, the state information before the discharging, and the state information after the discharging, and the control parameter carried in the control instruction adopted by the current charging or discharging, and stored in the historical usage record in the cloud, so as to update the historical data, so that when the charging or discharging is required next time, the dynamic adjustment of the charging or discharging may be performed according to the latest multiple historical records, so as to improve the service life and the service cycle of the battery.
In the method for controlling charging and discharging of the battery, under the condition that the electric quantity of the electric scooter is monitored to be lower than a threshold value and/or a charging and discharging instruction is received, state information of the battery of the electric scooter is obtained, the control instruction is determined according to the state information and/or the historical use record of the battery, and the electric scooter is controlled to charge or discharge the battery according to the control instruction.
