Abstract

The invention provides a boost type battery charging management system and a control method thereof. The system comprises a boost converting circuit and a charging control circuit, wherein the boost converting circuit receives direct current input voltage, boots the direct current input voltage to obtain an output signal in a converting mode, and the output signal charges a battery. The charging control circuit is connected with an output end of the boost converting circuit, when voltage of the battery is smaller than first threshold voltage, the charging control circuit adjusts the output signal to maintain charging current of the battery is trickle current, and when the voltage of the battery is larger than the first threshold voltage, the output signal directly charges the battery, and the first threshold voltage is larger than the direct current input voltage.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a boost-type battery charging management system and a control method thereof. Background technique [0002] At present, the common battery charging management system is mainly based on the step-down topology. Its input terminal is powered by a power adapter, and the output terminal is connected to a single-cell or multiple-cell battery. Gradually becoming the mainstream USB power supply system in the market, its power supply voltage is generally rated at 5V, and the mainstream single-cell lithium battery can use the step-down topology to realize single-cell charging. However, as the power of consumer portable devices increases, the demand for multi-cell lithium batteries becomes more and more obvious. Therefore, the boost topology is gradually used in battery management systems with multiple lithium batteries connected in series. Corresponding comparisons are urgently needed. Matur...
