Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of a battery output power control method of the present invention, applied to a controller connected to a battery input, the method includes the steps of: s1, before the battery is connected to a load and is conducted, acquiring the output voltage of the battery and a plurality of working voltage intervals corresponding to the load, and acquiring a plurality of working current values corresponding to the working voltage intervals; specifically, the working process of the battery work is to control the output of the battery to the load through the controller. Before the controller controls the conduction of the battery and the load, the output voltage of the battery at the moment is acquired, namely the output voltage of the battery without the load is acquired. It can be generally understood that when the battery is not loaded, the corresponding output voltage is the maximum output voltage that the battery can normally output. And the working voltage interval corresponding to the load is obtained according to the load, the load can work under different voltages generally, and the corresponding working current values of the load can also be different under different working voltages due to the requirement of the output power of the load.
S2, confirming the working voltage interval corresponding to the outputable voltage to obtain a corresponding working current value as a target current value; and confirming the working current value corresponding to the load by taking the output voltage as the working voltage according to the output voltage of the battery, and taking the working current value as a target current value.
S3, when the battery is connected with a load and is conducted, setting the output current of the battery as an initial current value, wherein the initial current value is smaller than any working current value; specifically, at the instant when the battery is controlled to be in conduction with the load, the output current of the battery, which is the output current to the load, may be set at the same time. The output current, i.e. the starting current value, is a comparatively small value, i.e. smaller than an arbitrary operating current value. It can be understood that when the battery is connected to the load and turned on, because the output current of the battery to the resistor is limited to be very small, the initial voltage of the battery at this time is approximately the corresponding voltage when the battery is not connected to the load, that is, the output voltage of the battery.
And S4, adjusting the output current of the battery to the target current value according to a first preset step. Specifically, the output current of the battery is gradually increased according to a certain step until the target current value is reached, and by means of gradually increasing the output current, the situation that the load does not work and the circuit is abnormal due to the fact that the output voltage of the battery is too low and the load fails to be powered because of overlarge impact current can be avoided.
As shown in fig. 2, in an embodiment, the battery output power control method further includes: s5, acquiring the lowest voltage threshold of the battery according to the power supply of the controller; s6, acquiring real-time output voltage of the battery in the load conduction working process, comparing the real-time output voltage with the lowest voltage threshold, executing a step S71 when the real-time output voltage is equal to the lowest voltage threshold, executing a step S72 when the real-time output voltage is smaller than the lowest voltage threshold, and executing a step S73 when the real-time output voltage is larger than the lowest voltage threshold; s71, controlling the output current of the battery to be the target current value, and executing the step S6; s72, reducing the output current of the battery, and executing the step S6; s73, increasing the output current of the battery, and performing the step S6. Specifically, during operation, the battery's ability to output voltage is gradually reduced due to its power consumption. In general, in a circuit, a controller can work normally, and the circuit is considered to be normal, and the controller characteristic of the circuit can obtain the lowest power supply for control, namely the lowest voltage threshold of a corresponding battery. And in the process that the battery supplies power to the load, detecting the output voltage of the battery in real time, and controlling the battery to work at the current voltage when the real-time output voltage is equal to the minimum voltage threshold value so as to ensure that the controller can work normally. When the real-time output voltage is lower than the minimum voltage threshold, the fact that the battery is abnormal in power supply is indicated, and a circuit is affected, and at the moment, the voltage of the battery can be increased in a mode of reducing the output current of the battery to a load, so that the normal work of the circuit is guaranteed. When the real-time output voltage is larger than the minimum voltage threshold value, the real-time output voltage can increase the current in order to increase the output power of the battery to the load, and meanwhile, the real-time output voltage is ensured to gradually approach the minimum voltage threshold value.
In one embodiment, in the step S72, the reducing the output current of the battery includes:
and decreasing the output current of the battery according to a second preset step. Specifically, the process of reducing the output current of the battery may be gradually reduced in a certain step.
In one embodiment, in the step S73, the increasing the output current of the battery includes:
and increasing the output current of the battery according to a third preset step, wherein the third preset step is smaller than the second preset step. Specifically, the process of increasing the output current of the battery may be gradually increased in a certain step, wherein the increasing speed is slow relative to the decreasing speed. I.e. the third predetermined step is smaller than the second predetermined step. In one specific example, the controller detects the voltage every 50ms, and decreases current 20MA each time if the detected voltage value is below the threshold value, so that the voltage increases, and increases current 10MA each time if it is above the threshold value, until the voltage approximates the threshold value. It will also be appreciated that the threshold is a range, such as a threshold range of 3V to 3.2V, below which the current starts to decrease and above which the current increases at 3.2V.
In an embodiment, in the step S1, the acquiring the outputable voltage of the battery and a plurality of operating voltage intervals corresponding to the load includes: acquiring an upper limit voltage value and a lower limit voltage value of the load; setting a voltage range larger than the upper limit voltage value as a first voltage interval, and setting a voltage range smaller than the lower limit voltage value as a second voltage interval; dividing the upper limit voltage value and the lower limit voltage value according to a fourth preset step to obtain a plurality of third voltage intervals; the obtaining of the plurality of working current values corresponding to the plurality of working voltage intervals includes: the working current value corresponding to the first voltage interval is an upper limit current value corresponding to the load when the load is at the upper limit voltage value; the working current value corresponding to the second voltage interval is a lower limit current value corresponding to the load when the load is at the lower limit voltage value; and the working current values corresponding to the third voltage intervals are a plurality of working current values corresponding to the load when the load works in the third voltage intervals. Specifically, for the division of the operating voltage interval and the operating current value of the load, when the output voltage of the battery is higher than the upper limit voltage value of the load, the current of the battery does not increase with the increase of the voltage, and when the output voltage of the battery is lower than the lower limit voltage value of the load, the current of the battery does not decrease with the decrease of the voltage. Only in the normal working range of the load, the input voltage and the corresponding current of the load can change along with the change, and the division of the working voltage interval and the corresponding of the working current are carried out by taking the change as a standard.
In one embodiment, the battery output power control method of the present invention further includes: before increasing the output current of the battery, determining whether the current value meets the target current value, if not, executing the step S73; and if so, controlling the output current of the battery to be the target current value. That is, in increasing the output current of the battery, when its current value has satisfied the target current value, even if the voltage value is still higher than the minimum threshold value, it will no longer adjust the current value, and output directly in accordance with the present current value and the present output voltage.
In one embodiment, the battery output power control method of the present invention further includes: before reducing the output current of the battery, whether the output current of the battery is lower than any working current value is determined, if not, the step S72 is executed, and if yes, the power supply of the battery to the load is cut off. That is, in the process of reducing the current output, after the current is reduced, the output voltage of the load is still not increased, and when the current is reduced to be lower than the current at which the load can work, the power supply of the battery to the load is cut off. At this time, the battery power cannot work normally, and the battery needs to be replaced.
In an embodiment, the fourth preset step of the division of the operating voltage interval is 0.1V. If the battery output is more than 4.4V, the corresponding working current is 700mA, the corresponding working current is 600mA, the corresponding working current is 500mA, the corresponding working current is 200mA, the corresponding working current is 500mA, the corresponding working current is … …, and the corresponding working current is less than 3.6V.
In one embodiment, said first preset step controlling the supply of power from the battery to the load is 10mA during the start-up of the supply of power. For example, the current to the load is increased from 10mA, 20mA … … in order until the target current value is reached.
As shown in fig. 3, a battery output power control apparatus according to the present invention is connected to a battery and operated by the battery, and includes: the first execution unit 110 is configured to, before the battery is connected to a load and turned on, obtain an outputable voltage of the battery and a plurality of working voltage intervals corresponding to the load, and obtain a plurality of working current values corresponding to the plurality of working voltage intervals; the second execution unit 120 is configured to confirm the working voltage interval corresponding to the outputable voltage, so as to obtain a corresponding working current value as a target current value; a third executing unit 130, configured to set an output current of the battery as an initial current value when the battery is connected to a load and turned on, where the initial current value is smaller than any of the working current values; and a fourth executing unit 140, configured to adjust the output current of the battery to the corresponding working current value according to a first preset step. Specifically, the working process of the battery work is controlled through the device. Before controlling the conduction of the battery and the load, the output voltage of the battery at the moment is acquired, namely the output voltage of the battery without the load is acquired. It can be generally understood that when the battery is not loaded, the corresponding output voltage is the maximum output voltage that the battery can normally output. And the working voltage interval corresponding to the load is obtained according to the load, the load can work under different voltages generally, and the corresponding working current values of the load can also be different under different working voltages due to the requirement of the output power of the load. And confirming the working current value corresponding to the load by taking the output voltage as the working voltage according to the output voltage of the battery, and taking the working current value as a target current value. At the instant of controlling the conduction of the battery and the load, the output current of the battery, which is the output current to the load, may be set at the same time. The output current, i.e. the starting current value, is a comparatively small value, i.e. smaller than an arbitrary operating current value. It can be understood that when the battery is connected to the load and turned on, because the output current of the battery to the resistor is limited to be very small, the initial voltage of the battery at this time is approximately the corresponding voltage when the battery is not connected to the load, that is, the output voltage of the battery. The output current of the battery is gradually increased according to certain steps until the target current value is reached, and the method for gradually increasing the output current can avoid that the load does not work and the circuit is abnormal because the output voltage of the battery is too low due to overlarge impact current and the power supply failure to the load. Meanwhile, the output voltage and the current of the battery are set according to the relation between the working voltage of the load and the corresponding working current, so that the output power of the battery to the load is the maximum.

Specifically, during operation, the battery's ability to output voltage is gradually reduced due to its power consumption. In a general circuit, the circuit is considered to be normal if the control device can work normally, and the lowest power supply of the control device, namely the lowest voltage threshold of the corresponding battery, can be obtained. And in the process that the battery supplies power to the load, detecting the output voltage of the battery in real time, and controlling the battery to work at the current voltage when the real-time output voltage is equal to the minimum voltage threshold value so as to ensure that the control device can work normally. When the real-time output voltage is lower than the minimum voltage threshold, the fact that the battery is abnormal in power supply is indicated, and a circuit is affected, and at the moment, the voltage of the battery can be increased in a mode of reducing the output current of the battery to a load, so that the normal work of the circuit is guaranteed. When the real-time output voltage is larger than the minimum voltage threshold value, the real-time output voltage can increase the current in order to increase the output power of the battery to the load, and meanwhile, the real-time output voltage is ensured to gradually approach the minimum voltage threshold value.
