Abstract

The invention relates to an intelligent adaptive charge management device for a lithium polymer storage battery and a control system thereof. The intelligent adaptive charge management device mainly comprises a programmable charge control chip, a storage battery, a temperature acquisition module, a battery parameter model base and the like. During charging and discharging, the programmable charge control chip detects the data, such as the current, voltage, temperature and the like, of the storage battery in real time, and transmits the data to a charge management control unit therein to acquire an output signal through calculation; the output signal is compared with a pre-stored standard value in the battery parameter model base; the comparison result is transmitted to the charge management control unit to acquire the corresponding charging current and voltage values through calculation; and a charge control module is started to perform charge management on the storage battery so as to fulfill the aim of adaptive charging, completely overcome the overcharging phenomenon and radically avoid thermal runaway. The charge management device not only overcomes the defect that the conventional charger has a single charging mode, but also enables a nickel-cadmium battery charging device and a lithium ion battery charging device to be used universally.

Description

technical field [0001] The present invention relates to a charging management device and control system for a lithium polymer battery, in particular to a portable device such as a notebook computer, a pocket video recorder, a digital camera, etc. , communication, military and other industries) intelligent adaptive charging management device and control system for lithium polymer batteries required. Background technique [0002] With the increasing miniaturization, weight reduction and high performance of portable devices and their increasing popularity, the market for lithium-ion secondary batteries as power sources is spreading rapidly. Currently, the mainstream of secondary batteries is lithium ion secondary batteries. [0003] The advantages of lithium-ion secondary batteries are safe use, long cycle life, light weight, small size, high specific energy, and no pollution. Compared with the past secondary batteries (nickel-cadmium batteries, nickel-hydrogen batteries), it ...
