Abstract

The invention discloses a battery charging power system. The battery charging power system comprises a direct current power source, a battery module and a charging management module, wherein the charging management module comprises an input protection unit, a soft start switch unit, a DC/DC (direct-current/direct-current) conversion unit and a battery in-situ detection unit; the input protection unit is connected between the direct current power source and the soft start switch; the battery in-situ detection unit is connected with the battery module and a first control terminal of the soft start switch unit to send a first control signal to the soft start switch unit, and the soft start switch unit starts up or shuts off the DC/DC conversion unit according to the first control signal. Compared with the prior art, the charging management module comprises the input protection unit and the battery in-situ detection unit, and the input protection unit can protect the direct current power source, so that safety and reliability of the charging process are improved; the battery in-situ detection unit can detect the in-situ state of the battery module and shut off the DC/DC conversion unit when the battery module is not in the position, and accordingly, energy waste is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of battery management, and more specifically relates to a battery charging power supply system. Background technique [0002] At present, whether it is digital control or analog control, the charging of the battery is composed of two independent parts: one is the DC power supply, which provides DC energy for charging the battery (the battery can only be charged with DC energy); the other is the DC power supply for the battery. Carry out the management and protection part of charging. The generation of DC power generally includes AC / DC high-frequency switching power supply, linear power supply, solar energy and other DC power supplies, among which high-frequency switching power supply is the main method to provide DC power supply for battery charging. [0003] The Chinese Patent No. 200720076436.4 and the patent application titled "Charging Management Control Circuit for Battery Chargers" disclose a ...
