In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
For the battery module, it includes a plurality of parallelly connected, but hot plug's battery, is charging to the battery module through the charger (including UPS (Uninterruptible Power Supply, uninterrupted power source), charging stake etc.), and when the battery module can suddenly increase battery quantity, the output current of charger can increase rapidly to guarantee that the constant voltage charges to the battery module. The output current increases rapidly in a short time, and the switching device in the charger can bear larger anti-peak stress and current stress, thereby affecting the service life of the charger equipment, which is not considered in the prior art. The embodiment of the invention provides a charging control device and power supply equipment for solving the problems.
Fig. 1 is a schematic structural diagram of a charging control device according to an embodiment of the present invention. As shown in fig. 1, a charging control device may include an acquisition module 10, a threshold module 11, a clipping module 12, and a control module 13.
The collection module 10 is configured to collect a current charging current value of the charging circuit 20 for charging the external load 30, and send the current charging current value to the threshold module 11.
The threshold module 11 is configured to add the current charging current value to a preset increment to obtain a current threshold value, and send the current threshold value to the clipping module 12.
The limiting module 12 is configured to determine an adjustment value according to the target charging current value and the current threshold value, and send the adjustment value to the control module 13; when the target charging current value is not equal to the current threshold value, the adjustment value is the smaller one of the target charging current value and the current threshold value; when the target charging current value is equal to the current threshold value, the adjustment value is the target charging current value.
The control module 13 is used for controlling the charging current of the charging circuit 20 for charging the external load 30 to adjust to the adjustment value.
Optionally, the charging control device provided by the embodiment of the invention is used for controlling the charging circuit so as to charge the external load by the charging circuit. The collection module 10 may be a collection circuit or a current sensor, etc., and collect the current value of the output end of the charging circuit 20 as the current charging current value, or collect the current value of the input end of the external load 20 as the current charging current value, and the specific collection position may be selected according to the actual requirement.
Optionally, the current threshold value is obtained by adding the current charging current value to a preset increment, and in general, the preset increment may be preset in the threshold module, and may be a fixed value or a dynamically adjusted variable quantity. The current charging current value is changed all the time, and when the current charging current value is changed, the current threshold value is also changed. That is, the current threshold value provided by the embodiment of the invention can be changed in real time according to the current charging current value.
Alternatively, when the target charging current value is not equal to the current threshold value, it indicates that the charging current output by the charging line 20 is still rising, and the adjustment value is the smaller of the target charging current value and the current threshold value; when the target charging current value is equal to the current threshold value, it indicates that the charging current output by the charging line 20 is not substantially changed, and the adjustment value is the target charging current value.
The working principle of the charge control device provided by the embodiment of the invention is as follows:
First, the acquisition module 10 acquires a current charging current value and transmits the current charging current value to the threshold module 11. Next, the threshold module 11 adds the current value to a preset increment to obtain a current threshold value, and sends the current threshold value to the clipping module 12. Again, the clipping module 12 compares the target charging current value with the current threshold value, determines an adjustment value, and sends the adjustment value to the control module 13. Finally, the control module 13 controls the charging current of the charging line for charging the external load to be adjusted to the adjustment value. The current threshold value is updated after the current charging current value is acquired by the acquisition module every time, and the increasing trend of the charging current is delayed by continuously updating the current threshold value, so that the charging to the external load is reliable.
The embodiment of the invention collects the current charging current value of the charging circuit for charging the external load through the collection module and sends the current charging current value to the threshold module; the threshold module adds the current charging current value with a preset increment to obtain a current threshold value, and sends the current threshold value to the amplitude limiting module; the amplitude limiting module determines an adjustment value according to the target charging current value and the current threshold value and sends the adjustment value to the control module; when the target charging current value is not equal to the current threshold value, the adjustment value is the smaller one of the target charging current value and the current threshold value; when the target charging current value is equal to the current threshold value, the adjustment value is the target charging current value; the control module controls the charging current of the charging circuit for charging the external load to adjust to the adjustment value. The increasing trend of the charging current of the charging circuit is limited by different thresholds, so that the service life of devices in the charging circuit can be prolonged, and the reliability of charging to external loads can be improved.

The output value of the voltage outer loop can be used as the current given value of the current inner loop.
