文档介绍：数字式智能充电器
摘要
随着生活中越来越多的人使用移动电子设备,各种各样的充电电池也应运而生;对于不同的充电电池,我们需要选择不同类型的的充电器,但充电器的性能却不能满足充电电池的充电需求;在硬件电路和软件设计方面还存在许多功能上的不足。面对目前市场上不同类型充电器功能上的不完善,结合各种充电电池的实际需求;设计了一种数字式智能充电器。
数字式智能充电器可以给端电压为 ~、镍氢电池和锂电池进行充放电,同时还可以给小容量且低压的密封铅酸蓄电池进行充电。本设计使用AVR单片机对充电电池实行数字化智能充电控制,实时监控电池在充电时的及时充电电压和及时充电电流,使充电过程按理想的充电曲线进行,同时为了更合理的使用电池,数字式智能充电器中还加入了对电池的放电模块,对不同类型的电池进行放电以至于可以延长电池的使用寿命;充电器使用了电压控制、温度控制、PID恒流控制,以便达到既能保护电池,还可以使电池充满的效果,实现了数字式智能化充放电。

INTELLIGENT DIGITAL CHARGER
ABSTRACT
As more and more people are using mobile devices for life, all kinds of rechargeable batteries also arises at the historic moment; For different rechargeable battery, we need to choose different types of chargers, but charger performance cannot meet the demand of rechargeable battery charge; There are many in the hardware circuit and software design function. Faced with different types of chargers on the market at present the function of the imperfect, combined with the actual needs of all kinds of rechargeable batteries; We design a digital intelligent charger.
Intelligent digital charger can give a voltage of V ~ V nickel-cadmium batteries, nickel metal hydride batteries and lithium battery charge and discharge, at the same time also can give small capacity and low voltage battery recharged. This design use AVR single chip puter to control charging rechargeable batteries for digital intelligent, real-time monitoring of battery during charging charging voltage and charging current in time in time, the charging process, according to the ideal charging curve in order to more reasonable use of the battery at the same time, digital intelligent charger also joined in the discharge of battery module, for different types of battery discharge that can prolong the service life of the battery; Charger uses the voltage control, temperature control, PID constant current control, in order to achieve both can protect the battery, you can also make the battery effect, realized
