Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] When the monitoring unit only controls the output voltage of the rectifier module, even if the load current keeps changing, due to the characteristics of the constant voltage source of the rectifier module, the voltage output from the rectifier module to the battery will basically not change, so the charging current of the battery will not change. Change. Based on the above analysis, the embodiment of the present invention proposes that when the actual charging current is greater than the preset charging current limit point, the output voltage of the rectifier module is adjusted downward step by step, so that the actual charging current infinitely approaches the preset charging current. The set charging current limit point ensures that the charging current can reach the current limit value quickly and accuratel...

Abstract

The invention relates to a battery current management method and a battery current management device. The method comprises the steps that: whether an actual charging current is higher than a preset charging current limit point is determined; and when the actual charging current is higher than the preset charging current limit point, a rectifier module output voltage is regulated with a variable step size successive downward adjustment manner according to the difference between the actual charging current and the preset charging current limit point, such that the actual charging current approaches the preset charging current limit point. The invention also provides a battery current management device. With the method and the device provided by the invention, charging current change caused by load fluctuations during a battery charging process can be avoided, such that charging effect can be ensured, and storage battery service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of communication power supplies, in particular to a battery current management method and device. Background technique [0002] In a communication power supply system, it is usually necessary to charge the battery. The charging of the existing communication power battery is generally completed by a rectification module, which can complete the AC-DC conversion, and output an appropriate charging current according to the control of the monitoring unit to charge the battery. In practical applications, the traditional battery current management scheme is based on the way that the monitoring unit limits the current of the rectifier module. The most important feature of the current limiting method is to immediately adjust the output current limiting point of the rectifier module when it is detected that the charging current of the battery exceeds or falls below the current limiting point. Since the current outpu...
