动力电池化成工艺的节能型自动充放电系统设计

Design of An Energy-saving and Automatic Charging & Discharging System for Formation Process of Power Batteries

针对传统的电阻放电式动力电池化成方法,设计了一种基于电池对充化成的节能型自动充放电系统。该系统以dsPIC5015单片机为控制核心,构建了1个较智能的软硬件平台,通过Boost升压整流电路,将需要放电的电池进行升压整流,再向需要充电的电池充电,从而充分利用电池放电的电能。实验证明该系统的能量利用率可达到72%以上,相对于电阻放电模式有效地降低了电能损耗,同时实现了系统工作自动化,极大地减轻了操作人员的工作压力,具有很好的应用前景。

Different from the traditional way of using resistors to format batteries, an energy-saving and automatic charging and discharging system is designedon basis of formatting each other. With a dsPICS015 microcontroller as the control kernel, the system builds an intelligent hardware and software platform. It uses a boost circuit to charge the battery from another that needs to be discharged, which make a full use of the electrical energy. The experiments prove that the energy utilization of the system can reach more than 72%. Compared with the resistance-discharging mode, this system can reduce power consumption effectively and realize automation of the work to drop working pressure of operators, so it has a wide foreground of application.
