铅酸电池智能充电器设计
摘要
铅酸蓄电池在直接供电和备用供电等场合获得了比较广泛的应用。为了更加有效合理的对铅酸蓄电池充电的作用,所以在给蓄电池充电的过程中,应合适的给电池充电,从而减少充电时对电池的损害。达到保护电池,维持电池的使用寿命。由于蓄电池在充电时的温度是变化的,所以在设计充电器时应把温度考虑到充电的因素当中。对充电过程的进一步精确控制。本文中铅酸蓄电池充电器主要用到的芯片UC3909,介绍了UC3909控制智能充电器的工作原理,分析了电池充电时的各种状态,具体解决方案,做到对电池的伤害最小,并设计了应用于铅酸电池硬件控制电路,监控电路的设计方案,对UC3909,HT46R23等芯片做了简单介绍,并且还对蓄电池充电器系统硬件电路的设计做了较为明确的说明和具体的软件编程。另外,本文还对电池的充电电压和电池温度的监控流程进行了初步设想,从而实现充电器的智能化。对蓄电池在充电时起到了一定的保护作用,基本上解决了充电时的电能浪费和能源浪费的问题。为今后的减排节能起到了一定作用。

Intelligent lead-acid battery charger design
ABSTRACT
Lead-acid battery in direct power supply and backup power supply has been widely used. In order to more effective and reasonable, the function of lead-acid battery charging so on battery charging process, should be suitable for the battery, and thus to minimize damage to the battery when charging. To protect the battery, to maintain the service life of batteries. Due to the temperature of the battery when charging is changing, so in the design of the charger should be the temperature when considering the factors of charging. Further precise control of the charging process. The chip UC3909 lead-acid battery charger is mainly used in this paper, introduces the working principle of intelligent charger UC3909, analyzes several kinds of battery charging status, the specific solutions, to achieve the minimum damage to the battery, and designs the hardware control circuit used in lead-acid battery, the control circuit design, to UC3909 HT46R23 chip made simple introduction, but also on the battery charger system clear instructions to the hardware circuit design and software programming in detail. In addition, this article also for charging voltage of the battery and battery temperature monitoring process has carried on the preliminary conception, so as to realize the intelligent of the charger. For the protection of the battery when charging have played a role, basically solved the charging electric energy waste and energy waste problem. Play
