资料介绍

在智能手机与LED手电筒等电子产品中,均需对锂离子电池进行充电,针对锂离子电池充电器进行了软件和硬件的设计。软件是基于单片机8051F020程序设计,实现了电池失效的筛选、充电速度快、充电电压电流稳定、充电锂离子电池多规格的自动识别、充电结束自动关闭输出,充电过程具有过温保护,输出过压欠压保护,输入输出反接保护等功能,并能实时监测和显示充电状态。硬件上的AC/DC是通过TOP234控制的反激电路实现,充电电流监测是通过LT6106实现,过温保护是通过温度开关KSD-01F组成的电路实现,输出过压欠压保护是通过瞬态抑制二极管P6KE6.8CA和P6KE12以及三极管2SC945组成的电路实现,输入输出反接保护是通过凌特LTC4357芯片组成的电路实现,针对电网电压电流浪涌采用热敏电阻NTC16D-11进行抑制,确保AC/DC输入电压稳定。该款充电器对不同规格的锂离子电池智能充电具有高效,安全、稳定、智能可靠的特点。

In this paper,the software and hardware of lithium-ion battery charger are software is based on 8051F020 MCU program realizes screening of battery failure,fast charging speed,stable charging voltage and current,automatic identification of multi-specifications of charged lithium-ion batteries,automatic closing of output after charging,and functions of over-temperature protection,over-voltage and under-voltage protection of output and input-output reverse connection protection during charging,as well as real-time monitoring and displaying of charging on hardware is realized by flyback circuit controlled by TOP234,charging current monitoring is realized by LT6106,overtemperature protection is realized by circuit composed of temperature switch KSD-01F,output overvoltage and input and output backconnection protection is realized by circuit composed of Lingte LTC4357 circuit realizes that the thermistor NTC16D-11 is used to suppress the voltage and current surge in the power grid to ensure the stability of AC/DC input voltage.
