Abstract

The invention discloses an LED (light emitting diode) emergency lamp battery management device and method thereof. The LED emergency lamp battery management device comprises a level amplification and conversion unit and a remote control unit and is characterized by also comprising a sampling and balancing unit, a microcontroller CPU (central processing unit), a low-voltage self-cut unit, a charger and a work mode control unit. The device integrates the functions of battery monitoring and balancing, battery charge / discharge protection, multi-work mode switching, remote control and the like, and can perform effective monitoring and charge / discharge management and control on the battery pack of the emergency lamp so as to avoid over charge and over discharge of the battery, reduce the attenuation speed of the battery performance, prolong the service life of the battery and further improve the safety and reliability of the emergency lamp.

Description

technical field [0001] The invention relates to the field of automatic control, and relates to an LED emergency light battery management device and a method thereof. Background technique [0002] At present, with the widespread application of lithium-ion batteries, nickel-metal hydride batteries, and nickel-zinc batteries in emergency lights, the safety and reliability, service life and efficiency of backup battery packs have a crucial impact on the performance of emergency lights. In the existing emergency lights, because the power supply battery is in an uncertain cyclic working state such as charging, shelving, and discharging for a long time, the life of the single battery and the stability of the power supply are relatively greatly affected. [0003] Existing emergency light products generally can only work in the emergency mode, that is, start to work when the 220V AC power supply stops. This single working mode limits the scope of application of emergency lights. Th...
