摘要
针对物流行业中使用的RFID手持机功耗较大,需要大容量锂电池供电的情况,本文设计了RFID手持机锂电池快速充电电路。本文分为两部分,第一部分为根据RFID手持机的功耗需求,设计出了将单节锂电池的电压升压到5V供手持机工作的DC-DC变换电路;第二部分设计出适用于2000mAh以上锂电池充电的充电电路。实验数据表明该电路是有效的。
The Handheld RFID Reader used in logistic industry always need single high volume Lithium battery as the power supplier. Based on the power need of the handheld RFID Reader, a rapid charge circuit was put forwarded. The paper has two parts, one is a step-up DC-DC convert circuit, which was used to raise the voltage of a single lithium battery to 5V, the second parts is a power charge circuit for a single lithium battery with the volume larger than 2000mAh. The experimental results of the circuit designed show that the circuit is effective.
