Fig. 1 is a schematic diagram of one application scenario of a charging method according to some embodiments of the present disclosure.
As shown in fig. 1, when the battery power of the automated guided vehicle 101 is smaller than the set power value, the automated guided vehicle may be autonomously parked on the charging device 103. At this time, the automated guided vehicle 101 may transmit the electric quantity information to the charging server 102. After receiving the electric quantity information of the automated guided vehicle 101, the charging server 102 obtains the temperature information of the surrounding environment through a device such as a temperature sensor. Then, the charging server 102 matches the power information and the temperature information with preset conditions. The preset conditions are used for checking whether the electric quantity information and the temperature information respectively meet the charging conditions and the temperature conditions. Wherein, the charging condition may be: the battery capacity is 1% -50%; the temperature conditions may be: the ambient temperature is between 0 ℃ and 30 ℃. When the electric quantity information and the temperature information match with the preset conditions, it is indicated that the battery of the automated guided vehicle 101 can be charged. The charging server 102 may calculate charging current information according to the power information and the temperature information, and generate a charging instruction corresponding to the charging current information. The charging instruction is for instructing the charging device 103 to perform a charging operation on the battery of the automated guided vehicle 101. Therefore, the charging current information can be calculated aiming at the ambient temperature, so that the charging efficiency of the battery is improved and the loss of the battery is reduced when the battery is charged according to the charging current information. Wherein the charging efficiency can be represented by the amount of charge per unit time.
It should be understood that the number of unmanned vehicles 101, charging servers 102, and charging devices 103 in fig. 1 is merely illustrative. There may be any number of unmanned vehicles 101, charging servers 102, and charging devices 103, as desired for implementation.
With continued reference to fig. 2, fig. 2 illustrates a flow 200 of some embodiments of a charging method according to the present disclosure. The charging method is applied to the unmanned carrier and comprises the following steps of:
step 201, in response to detecting a charging request signal of the unmanned carrier, acquiring electric quantity information and temperature information of a battery of the unmanned carrier.
In some embodiments, the executing body of the charging method (e.g., the charging server 102 shown in fig. 1) may acquire the power information and the temperature information through a wired connection or a wireless connection. It should be noted that the wireless connection may include, but is not limited to, 3G/4G/5G connection, wiFi connection, bluetooth connection, wiMAX connection, zigbee connection, UWB (Ultra Wide Band) connection, and other now known or later developed wireless connection.
When the automated guided vehicle 101 detects that the battery power is less than the set power after completing the task, it may autonomously dock on the charging device 103 and send a charging request signal and power information to the execution body. The charge information may be percentage data of the battery capacity. When the execution body detects the charge request signal, the electric quantity information of the automated guided vehicle 101 and the temperature information of the battery may be acquired. Wherein the temperature information may be used to characterize the ambient temperature at which the battery is charged. The temperature information may be the current ambient temperature detected by the sensor of the automated guided vehicle itself, or the current ambient temperature detected by the charging device 103. Thus, the accuracy and the effectiveness of calculating the charging current information are ensured.
And 202, calculating charging current information according to the electric quantity information and the temperature information in response to the electric quantity information and the temperature information meeting preset conditions.
In some embodiments, the execution subject may match the acquired power information and temperature information with preset conditions. When the matching is successful, the battery can be charged; when the match is unsuccessful, an alert signal may be issued. The matching method may be that the charge information and the temperature information satisfy a charge condition and a temperature condition, respectively. Or respectively selecting corresponding weight values according to the values of the electric quantity information and the temperature information, and comparing the sum of the two weight values with the set weight value to further determine whether the charging condition is met. For example, the charging conditions may be: the battery capacity is 1% -50%; the temperature conditions may be: the ambient temperature is between 0 ℃ and 30 ℃. Alternatively, the charging conditions may be: the weight value of the battery capacity is 0.5 when the battery capacity is 1% -50%; weight value at 50% -80% is 0.2; the weight value at 80% -100% is 0. The temperature conditions may be: the weight value of the environment temperature is 0.5 when the temperature is between 0 and 30 ℃, and the weight value is 0.1 when the temperature is between 30 and 50 ℃; the weight value is 0 when the temperature is more than 50 ℃; the weight value is 0.1 at the temperature of-20 ℃ to 0 ℃; the weight value at less than-20 degrees celsius is 0. The set weight value may be a sum of a weight value of the battery capacity and a weight value of the ambient temperature greater than 0.8. After the matching is successful, the executing body can calculate charging current information according to the electric quantity information and the temperature information. The execution body may acquire the battery capacity and then take a set percentage of the battery capacity as a value of the charging current. For example, the battery capacity is 200 amp hours. The set percentage may be 10%, and the charging current information may be 10 amps.
Step 203, generating a charging instruction corresponding to the automated guided vehicle based on the charging current information.
In some embodiments, after determining the charging current information, the executing body may generate the charging instruction based on the charging current information. The execution body may transmit a charging instruction to the charging device 103. After receiving the charging instruction, the charging device 103 charges the battery of the automated guided vehicle 101 according to the charging current information included in the charging instruction.
The charging current information is obtained through the charging method of some embodiments of the present disclosure, so that the charging efficiency of the battery is improved. Specifically, the reason why the charging efficiency of the battery is not high is that: the effect of temperature on the battery charging process is not considered during charging. Based on this, the charging method of some embodiments of the present disclosure first matches, when a charging request signal of the automated guided vehicle is detected, electric quantity information and temperature information of a battery of the automated guided vehicle with charging conditions, wherein the temperature information is used to characterize an ambient temperature when the battery is charged. And when the matching is successful, calculating charging current information according to the electric quantity information and the temperature information. That is, the charging current information considers the influence of the ambient temperature at the time of charging, thereby contributing to the improvement of the charging efficiency of the battery. Also because the charging current information considers ambient temperature for the charging process has reduced the loss to unmanned carrier's battery, is favorable to improving unmanned carrier's battery life.
With continued reference to fig. 3, fig. 3 illustrates a flow 300 of some embodiments of a charging method according to the present disclosure. The charging method comprises the following steps:
step 301, in response to detecting a charging request signal of the unmanned carrier, acquiring electric quantity information and temperature information of a battery of the unmanned carrier.
The content of step 301 is the same as that of step 201, and will not be described in detail here.
In step 302, in response to the electric quantity information meeting the charging condition, and the temperature information meeting the first temperature condition, a charging current calculating operation is performed.
When the electric quantity information meets the charging condition and the temperature information meets the first temperature condition, the execution main body can directly perform the operation of calculating the charging current. Wherein, the charging condition can be that the electric quantity information is 1% -50% of the battery capacity; the first temperature condition may be an ambient temperature in the range of 0 degrees celsius to 30 degrees celsius. At this time, the execution subject can directly pass the charge current through the power information and the temperature information.
In some alternative implementations of some embodiments, the calculating the charging current operation may include the steps of:
the first step is to calculate a first difference between the electric quantity information and an electric quantity threshold value corresponding to the charging condition, and calculate a second difference between the temperature information and a first temperature threshold value corresponding to the first temperature condition.
In order to improve the charging efficiency of the battery, the charging current may be increased. For this purpose, the execution subject may first calculate a first difference of the electric quantity information and the electric quantity threshold value corresponding to the above-described charging condition, and a second difference of the temperature information and the first temperature threshold value corresponding to the above-described first temperature condition.
And a second step of calculating first charging current information according to the electric quantity information in response to the first difference value being greater than or equal to a second difference value, or else, calculating second charging current information according to the temperature information.
The first difference and the second difference are determined by corresponding power thresholds and first temperature thresholds. The charge threshold may be 50% and the first temperature threshold may be 30 degrees celsius. The larger the difference, the larger the corresponding charging current may be. In order to increase the charging current, one of the two differences, which is the larger difference, may be selected as the reference. When the first difference is greater than or equal to the second difference, the first charging current information may be calculated according to the electric quantity information. Otherwise, calculating second charging current information according to the temperature information.
In some optional implementations of some embodiments, the calculating the first charging current information according to the power information may include: and calculating first charging current information based on a third difference value between the full power information of the battery and the power information.
The executing body may calculate a third difference between the full charge information of the battery and the charge information, and then calculate the first charging current information according to the third difference. For example, the power information is 10%, and the third difference is 100% minus 10% and is equal to 90%. At this time, the execution body may set the product of the rated maximum current of the battery and 90% as the first charging current information.
In some optional implementations of some embodiments, the calculating the first charging current information based on the third difference between the full power information and the power information of the battery may include: and determining an electric quantity weight coefficient matched with the third difference value, and calculating first charging current information based on the electric quantity weight coefficient.
The execution body may further match the electric quantity weight coefficient according to the third difference value, and then set the product of the rated maximum current of the battery and the electric quantity weight coefficient as the first charging current information. For example, when the third difference is 1% -30%, the charge weight coefficient may be 0.5; when the third difference is 30% -60%, the electric quantity weight coefficient can be 0.8; when the third difference is 60% -100%, the electric quantity weight coefficient can be 1.
In some optional implementations of some embodiments, the calculating the second charging current information according to the temperature information may include: and calculating second charging current information based on a fourth difference value between the first temperature threshold value and the temperature information.
The execution body may calculate a fourth difference between the first temperature threshold and the temperature information, and then calculate the second charging current information according to the fourth difference. For example, the first temperature threshold is 30 degrees celsius, the temperature information is 10 degrees celsius, and the fourth difference is 30 degrees celsius minus 10 degrees celsius and is equal to 20 degrees celsius. At this time, the execution body may calculate a temperature ratio of the fourth difference value to 30 degrees celsius, and set a product of the rated maximum current of the battery and the temperature ratio as the second charging current information.
In some optional implementations of some embodiments, the calculating the second charging current information based on the fourth difference between the first temperature threshold and the temperature information may include: and determining a temperature weight coefficient matched with the third difference value, and calculating second charging current information based on the temperature weight coefficient.
The execution body may further match the temperature weight coefficient according to the fourth difference value, and then set the product of the rated maximum current of the battery and the temperature weight coefficient as the second charging current information. For example, when the fourth difference is between 20 degrees celsius and 30 degrees celsius, the charge weight coefficient may be 0.5; when the fourth difference is between 10 ℃ and 20 ℃, the electric quantity weight coefficient can be 0.8; when the fourth difference is less than 10 degrees celsius, the charge weight coefficient may be 1.
And 303, performing a heating operation on the battery in response to the electric quantity information meeting the charging condition and the temperature information meeting the second temperature condition.
When the electric quantity information meets the charging condition, the temperature information meets the second temperature condition, which indicates that the battery needs to be charged, but the environment temperature corresponding to the temperature information is too low. At this time, in order to improve the battery charging efficiency, the battery may be first subjected to a heating operation. The heating operation may be performed by a temperature control device. The temperature control device may be a heat patch or the like. In practice, the temperature control device may or may not be in direct contact with the battery. When not in direct contact, the temperature control device can adjust the ambient temperature of the battery.
Step 304, in response to the temperature information of the battery after the heating operation satisfying the first temperature condition, performing the operation of calculating the charging current.
When the temperature information of the battery satisfies the first temperature condition after the heating operation, it is indicated that the charging may have a higher charging efficiency at this time. And (3) charging current, and performing the operation of calculating the charging current.
And step 305, performing a cooling operation on the battery in response to the electric quantity information meeting the charging condition and the temperature information meeting a third temperature condition.
When the temperature information meets the third temperature condition, the temperature information indicates that the temperature of the rhizoma polygonati is too high. At this time, in order to improve the battery charging efficiency, the battery may be first subjected to a cooling operation. The cooling operation can be realized by a temperature control device. The temperature control device may be a condensation plate or the like. In practice, the temperature control device may or may not be in direct contact with the battery. When not in direct contact, the temperature control device can adjust the ambient temperature of the battery.
And 306, performing the operation of calculating the charging current in response to the temperature information of the battery after the cooling operation meeting the first temperature condition.

Step 307, generating a charging instruction corresponding to the automated guided vehicle based on the charging current information.
The content of step 307 is the same as that of step 203 and will not be described in detail here.
With further reference to fig. 4, a flow 400 of further embodiments of a charging method is shown. The process 400 of the charging method includes the steps of:
step 401, in response to detecting a charging request signal of the unmanned carrier, acquiring electric quantity information and temperature information of a battery of the unmanned carrier.
And step 402, in response to the electric quantity information and the temperature information meeting preset conditions, calculating charging current information according to the electric quantity information and the temperature information.
Step 403, generating a charging instruction corresponding to the automated guided vehicle based on the charging current information.
The contents of steps 401 to 403 are the same as those of steps 201 to 203, and will not be described here again.
