Abstract

The invention discloses a control system for lithium battery power management, and relates to the field of lithium battery control, and the system comprises a voltage input module which is used for externally connecting voltage and supplying power to a battery power supply module and a time delay module; the battery power supply module is used for charging the battery; receiving the battery voltage information, and adjusting the voltage output to the battery according to the battery voltage; the battery module is used for a battery to store electric energy; compared with the prior art, the system has the beneficial effects that the output voltage of the battery power supply module is adjusted through the feedback module, the output voltage of the battery power supply module is relatively large at the beginning, and the charging voltage is reduced along with the increase of the battery voltage, so that a quick charging effect is constructed; whether battery charging is abnormal or not is detected through the time delay module and the charging fault detection module, the battery power supply module is adjusted to perform constant-voltage charging when charging is abnormal, and the battery charging effect is guaranteed.

Description

technical field [0001] The invention relates to the field of lithium battery control, in particular to a control system for lithium battery power management. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and uses non-aqueous electrolyte solution to store electrical energy. [0003] The current lithium battery charging and discharging control system on the market lacks an abnormality handling circuit for the battery charging circuit, so that when the charging circuit fails, the battery is often not fully charged, and users tend to think that the battery is faulty, resulting in misunderstandings and needs to be improved. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a control system for lithium battery power management, so as to solve the above-mentioned problems in the background art. [0005] To achieve the above object, the present ...
