1、word毕业设计论文外文文献 题 目：智能型充电器的电源和显示的设计院 系： 自动控制系 专 业： 工业自动化 姓 名： 指导老师： 填表日期： 2022年12日 .wordThe design of the lithium battery chargerIntroductionAccording to the size, weight and energy storage advantages of lithium ion rechargeable battery is being used in many applications. These batteries have been co

2、nsidered for the application of the preferred battery in portable computer, displacing NiMH and NiCad batteries, and cellular phones are quickly become the second major lithium battery market. The reason is obvious. Lithium ion batteries offer many advantages to the end consumer. In portable compute

3、rs, lithium ion batteries in the same conditions and the size and weight of cases than NiCad and NiMH can provide more lasting power. The same advantages are true for cellular phones. A phone can be made smaller and lighter if using Li ion batteries so without sacrificing battery life. When the lith

4、ium ion battery costs down, even more applications will This will change to a lighter and smaller technology. As consumers continue to demand the convenience, indicating that the market trend of recharging a continual growth in all the cells. According to the market data show that approximately abou

5、t two hundred million batteries will be lithium ion to be shipped in 1997 when compared with 600 million NiMH batteries. However, it is important to note that the electric core electric core three NiMH equivalent to a lithium ion when packaged into a battery pack. Therefore, the actual volume of the

6、 two is very close to the same year also marked the first.1997 yearli ion battery type used in the majority of portable computers, displacing NiMH for the top spot. The data show that in 1997 the European and Japanese batteries market showed a shift to lithium Ion in the application of the majority

7、of phones. Lithium ion batteries is an exciting battery technology must be to a high degree of attention. To understand these new batteries, this design guide explains these principles, the charging requirements and circuits to meet these needs.With the advent of handheld appliances more and more, t

8、he high performance, small size, light weight of the battery charger is also increasing demand. Continued progress in battery technology also requires charging algorithm more complex to achieve rapid and safe charging. Therefore need to be monitored more precisely on the charging process to shorten

9、the charging time. The maximum capacity of the battery, and to prevent damage to the battery.AVR is a step ahead in the competition, proved to be perfect the next generation charger control chip.Atmel AVR microprocessor is currently on the market can provide Flash with single, 8 of the most efficien

10、t RISC EEPROM and 10 ADC microprocessors. Since the program memory for Flash therefore, you can not like MASK ROM, there are several software versions of several models on the stock.Flash can be programmed before delivery, or after the PCB mount through ISP For programming, allowing the software upd
