Abstract

The invention belongs to the field of a battery charge-discharge control technology and in particular provides a module controller of a lithium ion battery pack. The module controller comprises a power supply circuit, a micro controller unit (MCU), a charge-discharge control circuit, a current detection circuit, a temperature detection circuit and a light-emitting diode (LED) display circuit. The charge-discharge control circuit comprises a charge control unit and a discharge control unit, wherein the charge control unit and the discharge control unit are controlled to realize the charge-discharge selection of the lithium ion battery pack through the MCU; and the current detection circuit is used for detecting a bus bar current of the lithium ion battery pack. The module controller provided by the invention can detect voltage, current and temperature of the lithium ion battery pack in the charge-discharge process, guarantee the lithium ion battery pack to charge and discharge reasonably, and does not appear the phenomenon of damaging the battery life caused by overvoltage, overcurrent, short circuit, over-temperature and the like, so that the battery can work durably and effectively.

Description

technical field [0001] The invention belongs to the technical field of battery charging and discharging control, and in particular relates to a module controller of a lithium-ion battery pack. Background technique [0002] As an energy storage element, the battery pack can be charged and discharged for multiple cycles, providing an important energy supply for the use of electrical, electronic and other equipment. To complete the charge and discharge control of the battery pack, a special control module is needed to realize it. Traditional battery packs are mainly nickel-cadmium battery packs and nickel-hydrogen battery packs. The charging method usually adopts a multi-stage constant current charging method: that is, first charge with a large current, then switch to a small current charge, and finally switch to a trickle charge; The discharge is controlled by a discharge regulator. This charging and discharging method has the following problems: the control circuit used in ...
